Grief! It has been too long! I have focused my energy to helping a friend get her work done for her thesis. It is now time for my stuff. I have a paper to finish, but it is getting there...

Fred, my old pal, loves to keep me company but I don't offer him any excitement up here in my small library nook.... but then again, he only has just so much energy for excitement. Do we, as mammals, have the energy when we get older but just can't get to it? Is it that our cells don't have the stuff to make the mitochondria to get us moving?

Sleep is good. My grandfather loved his dreams. He would wake from a dream laughing and then tried to explain the joke to my grandmother - who he had awakened from a sound sleep herself.... Somehow, the joke was not as funny in wake time. My grandmother would pat my grandfather and tell him to go get the punch-line again and re-tell it in the morning.... and then fall back to sleep.

Sleep. Cats are so good at it. Somehow even in Fred's advanced age, he can get into positions I wish I could. They drool when they sleep just like people.... Why, I am not surprised...

It has been exceptionally hot here. So, hot that Fred has had a hard time finding a good spot to sleep. He will find a spot, flop down, close his eyes - and you can tell by his ears that he is not happy... He will move to a new spot. There is a lot of agitation going on. Sometimes you can see it in the twitching back of a cat... they seem to be bothered by itchy things, too....

Mouse, his buddy, was so upset by the heat he thought perhaps the bathroom sink would be nice. He curled up there for a while - even tolerated the drip, and that was funny to watch - but he got the sink warm and so had to jump down and find yet another spot.... The endless search for a cool spot to lie down and sleep.

Sleep, Ernestine, my leopard tortoise, has a young male friend (also a leopard tortoise) courtesy of the Vet. His name is Jack. Jack has long legs and is shaped more like a football and is a very friendly guy. He loves Mouse the cat, but Mouse the cat does not trust a long-legged-variegated-mobile-rock heading like a beeline to him across the lawn..... EEEK!

Jack loves anything that is black and white or grey and white.... just like him. Ernestine stumps about eating grass and dropped fruit from the trees. then she takes naps.... under bushes where the soil is cool. And, jack goes to find her. He is young and doesn't know what to do with Ernestine. He understands she is something he should explore but he is confused. He tends to climb up the rocks and bushes around her. I will find him hung up dangling from branches just above her. I put him down next to her and in the afternoon I find them face to face or shoulder to shoulder tucked inside and asleep.

I have been wanting to write about my thoughts and findings on the connections between the simple molecules that form when organisms die to the molecules organisms make (while alive) to attract, distract, and manipulate each other... but today is Memorial Day. And I feel the need to add my voice to the roar that is building to this farce....



Memorial Day and Bush's War

How can anyone say that in defending the WAR we are defending our troops?

Our troops are living breathing human beings.

War is an act and it is not a living breathing life.

War is an action that we choose.

War does not breath air.

War does not feel.

War does not bleed and die.

War, however, is fed and supplied and it spreads.

War does not build houses or plant crops or cure diseases.

War does not change diapers or feed the poor.

War is what is in essence what is the worst that human beings do.

War is what is draped by those who promote and propagate it in ill fitting descriptions of necessity and patriotism and for our common good.

War not only kills those who fight but those who don't.

War is what scours the earth of human beings and of other life as well.

War does not stop when it ends.

War only stops when it never begins.

Chemosensory is essential for survival for life. Pheromones are chemicals that an organism releases externally to send information to another organism.... Some of these chemicals have been identified from animals such as moths and humans. Two interesting components to this story are about how animals find food plants and mates, and how plants hijack this trait for their own needs.

...So we find that the siphoned water from the pot that has mostly cattails causes lots of algae to grow and the pot with bulrushes mixed with the pot with no plants has little alga growth in comparison...


The mozzies loves the pot with the algal growth! Though the two pots have many mosquito larvae, the one with lots of algae has more that are ready to emerge! There are lots of places to hide or lots of food to eat?

But just look at the pattern of algae that floated to the bottom....

We know now that the water from the pots had lots of colloidal molecules or NOM or natural organic matter which, through electrostatic conditions, attracted to the metals that we spiked in the pots.... It kept the toxic metals suspended in the water column caused the change in the flagellate populations and may have killed the fish and dragonflies... . But look at the pattern of the algae on the bottom of the pot.... you are now looking at what the colloids looked like.... Last week they were floating in the water but now they are like curtains that have been cut from their curtain rods.... The colloids are like humic molecules with multiple spots which things (not so nice things) attach .... metals - PAHs - plasticizers, hormones.... This is the stuff that makes our water systems go bad. This is the stuff made of carbon molecules (dead things make these floating ghosts of carbon) which pick up the bad stuff we let flow down our roads into our rivers... and stream and oceans...

When did this tiger from Pit 91 of La Brea Tar Pits run? When the L.A. River ran through the Wilshire Miracle Mile passing by the Art Museum. This little ferocious beast fed upon flies, ants and such next to some other extrodinary animals which roamed the Los Angeles Basin.

It may have died before people came to the Americas. But, it ran in the muds of the L. A. River when mammoths and saber toothed tigers plunged into sticky tar and died. Camels and horses and condors and sloths... lions bigger then their African counter parts, died in the asphalt leaving their bones for us to marvel.

Chris Nagano determined this tiger thorax (amazing!!!) and one other tiger part in 1980.... Roy Snelling (hymenopterist) did the other two.... only four Cicindela parts at the museum for now .... just one C. oregona and two C. hemorrhagica and one unknown tiger.

Well, all of my mosquitoes have died... in both containers. It was just a small look into the pesticide issue.

But, was it only the pesticide?

We put herbicide and Tylenol and anti-psychotic drugs and mercury and zinc and PAHs ... Then a scum and a slick formed and cyano-bacteria bloomed and fungus formed on the dead mats...

Because all of the fish and insects died in all of the pots, then, two weeks later, mosquitoes laid their eggs and larvae hatched. We really needed to take a look at tolerances and toxicity.... But, we did not have all the time and, oh, that awful stuff... money, to conduct yet another study.... We are still processing all of the other samples.... leaves and stems and roots and water and soil and algae and fish and dragonflies .....

So, ...to just to watch the development of the mosquitoes from the pots... I scooped out enough for two batches (one collected two days after the first).... I realized I did not have enough egg cases, but I would note development and time and conditions and the final result - no matter what happened.

I did not mix the water between the two containers and when evaporation lowed the levels, I re-filled to the original mark with drinking water. Each plastic covered (screened) container had one good egg mass. The first container had very little water about one and a half centimeters deep (cottage cheese container).... The second one had three centimeters of water (same type of container and lid).

Within the first day I had mozzies in the first container. Two days later, the mosquitoes in the second container emerged. Four days after that the second container with the most water, all larvae died.

Looking closer at the differences between the two containers, I noticed that there was a lot of fungal growth on the dragonfly tests (skin left over from emerging larvae) in the second container. The leaves left in the first did not have this fungal growth (both samples came from the same pot). The strands of fungus were long, dark, and almost black, and needle like.

The first container with the first group of mozzies, had clumps of green on the bottom - see the picture. The second container was murky but had either ciliates or flagellates swimming. The first container also had the same types of protozoa but the water was clear. .....Mozzies, for all of their bad rap, filter water of protozoa and algae, so this made sense... but what happened to the second container?

One would think the container with the most water (the second one) would be more successful! Both containers were exposed to some light so that algae could grow. The first container's second batch of mozzies (four times bigger then the first group before they died) fed on the bodies of their brothers and sisters and algae.... The larvae in the second patch only developed to the size of the first batch and then died....

My friend found a paper that described a similar study of a wetland habitat where after adding metals to the water, a bloom of flagellates occurred..... As I recall in marine systems,.... some ocean dinoflagellates can become toxic when stressed. Also, in the marine environment, diatom blooms occur near the outflows from city sewage and urban runoff. Diatoms when stressed (pH changes, exposure to lead and other toxic metals) and deprived of normal river runoff - iron (this is a limiting factor for life in the ocean phytoplankton) - release domoic acid which is neurotoxic to vertebrates. I don't know what kind of flagellates are in our experimental freshwater system, but one wonders....


It's really all about balance isn't it.

poisonous scum

Down splashes the water! streaking down the street! swiveling around tires and slipping around oily stains! Leaves collect in pitching masses. Flotillas of cigarette butts gurgle and boil with human spit-um and dog, bird, and unknown animal shit and vomit. Parts of decaying animals lurking in the dark street drains, swallow the incoming waters and mix it all up with the pesticides and herbicides skimmed from silly urban "gardens."


Sunlight kills many of the floating micro-organisms hacked up from diseased lungs and sickly bowels. But enough of the organisms attach to the coffee cups and plastic bags that cram the storm drains that rush to the sea.

This is just a picture of some water in a plastic pot that used to be clear.
It used to be free of horrors.
There used to be mosquito fish (which ate the mosquitoes) and damsel and dragon flies (which ate the fish and mosquito larva and adults).

Then we poured pesticides and other PAHs and plasticizers and mercury and lead and zinc and Tylenol and estrogen and drugs that prevent psychotic episodes in people - all the stuff that run down our streets into the sea and lakes and rivers and streams.

First the fish died. Then the dragon flies died. Then the algae and cyano-bacteria pulled up from the soil which covered floor of the pots. There were greasy globules of oily substances that kept things floating in suspension, There grew a skin of a sort that slowly rotated in the changing temperatures of the day. The water never settled out. Then the fungus grew. Bubbling thick masses of black and pink burped musty puffs of spores. You can smell the fungus for many meters from the pots.

Then one day, floating on the top were many mosquito eggs. The larvae hatched. They wiggled to the surface to sucked in their first gulp of fresh air.

They ate the algae and shed their skins of chitin and toxins.
Then another batch emerged.

The first batch died then the second ate the dead of the first. Little round heads of mosquito larvae bob at the bottom of the pots. With each new batch of mosquito larvae, the water cleared. With each new batch of mosquito larvae, they became more and more tolerant of the pesticides and other toxins that might kill them. Finally, the adults emerge from their pupas, ready to mate ... hauling out their shoulders from the slick surface. Masses of flies dancing in the pools of dwindling sunlight. ... and then the females, ready to take their first blood meal so they can lay the next generation of mosquito - able to tolerate the insecticides that killed its predecessors....

Just the mocking bird and I. One can ponder ephemeral life .... my own and others. How silly it is to think we live forever. How frightening to think that we could be stuck in a 'heaven' of our own design.... strumming a harp or using up virgins.... floating toward some light... both of which sound like hell ... long sleep isn't so bad.

I can almost see people purposefully crushing the life of the entire planet .... every time I watch a television show or listen to a radio program they are selling car after car after car .... I can watch images of melting mountains of ice at poles with each new line of vehicle ... the deep ocean currents changing directions as the trucks roll by tearing out trees and planting lawns ...

The cold water sinks, and salt water is heavier and has a lower freezing point. Deep ocean water, is at or below freezing but is liquid from the its salinity and great pressure. The ocean waters are never still, they move and change latitudes and longitudes and pour around the contours of the sea floor and continental shelves. The surface temperatures are warmed at the equator. The winds and the currents pump the air and water like a heart from the pull of the moon, the temperature changes of the seasons, and by the changes of night and day. The deep earth vents, and the cold, melted freshwater from land further churn the oceans. Our over use of fossil fuels, the burning and destruction of forests, mountains of trash and manure, loss of green forested land for cement are all contributing to the change of CO2/N over O2....

There were a few other times when our planet went through such changes in a short period of time. The first great death happened when the first organisms to photosynthesize created so much oxygen it killed the methane breathers... Then there was another great death when atmospheric oxygen plummeted from 21% to less then 12 % in only 20 million years. Land vertebrates at sea level had the same amount of oxygen as if they were at present day 9,200 foot mountain ... The Late Permian Early Triassic saw 90 % of the ocean organisms die and 75 % of the land plants and animals die. What a horrible death it must have been for not only did the oxygen vanish, but CO2 increased and with it temperatures. The earth became a steamy hot box with not much to breath...

In the end, after hours. days, years of work, you must publish. Then after that, you hope that what you have done will be of use to those who come after you to do similar or related work. The tedium of much of the everyday stuff is like any other job, but perhaps more like the tedium of art.

The initial idea of a painting is exciting. Then the sketches begin. So many of the sketches that you produce are not up to the ideas that you think you have done in the past... doubts creep in... but that is all part of the fight. With a blank canvas, hope is renewed but then so are the new worries. For most of the painting, you hate it. Love returns only near the end where you just can't get enough of the brush strokes, the colors, the shapes. Damn!

I have been submerged in two very engrossing projects ... one that is testing the efficiency of wetlands in taking up pollutants (pesticides, PAHs, metals, drugs) by isolating the two major wetland plants and the soils from a source in the man made wetlands of Sweetwater Reservoir... and the other is sampling the runoff water from the parts of the Los Angeles Basin which feeds the Ballona Wetlands. Both studies can finish with many useful concepts and discoveries. They are both very labor intensive, and even with the simplest tools for collection, filtration, oxygen, sampling, and other thoughtful considerations of protecting and stabilizing pollution constituents after capture, there is just not enough people, time or money.

Liters and liters of water must be collected in hopes to capture the tiniest amount of some chemicals. The water must be prepared for storage, and then carefully kept from light. Many times the tiniest amounts, perhaps in parts per million (even trillion), can have dire effects on those (people and other animals) who drink or swim in the water. Then to isolate and find those compounds which have been shown to produce adverse affects, the equipment for finding them must be calibrated (and sensitive) to those amounts. Then the number of times the water must be collected (or for any other scientific study... the number samples ) must be high enough to demonstrate a trend - in other words - to have significance.

I can't explain how I feel about the weather. I should be very relieved about the rain. It is cold here in Pasadena - around 37 degrees F... and in Oklahoma it is 80 degrees F. But I worry about the possibility of too much water in a short time when the mountains' trees and shrubs have not had enough time to re-grow from past fires. The plants hold back the mud. The trees absorb the water. The native plants can handle the heat from the fire which the introduced weeds from urban development cannot .... so ..... what to do.

We had a hail storm this afternoon. Not as robust as a month ago where the stones were the size of marbles.

I have gone up to the mountain to take pictures of the hillsides to document the present conditions. If we continue to have lots of rain we may have mud slides. This could be very bad.

The mountains' geology and composition of sediments from ancient rivers (which created the San Gabriel Mountains) make a very porous and rocky (some rocks are quite huge) sludge when mixed with a great deal of water from rain and snow. Months after last years storms, waterfalls ran until late summer. The cold weather, this year, has brought the snow level to around 1300 feet above sea level in some parts. Last year's storms had in some parts of the mountains, 20 inches of rain! If something like that happens this season, even with all of the dredging of the bottom of the San Gabriel Dam by the County, we could have floods.

With so many housing developments at and near the mouth of the river the City of Azusa and others take chances with peoples' lives. Why do Cities allow development so close to the moth's of Rivers? .... so close to open oceans? .... so close to? ...... City Governments need to take more of an active role in the protection of their citizens.....

I learned just recently that the same area during World War II was a site of a nerve gas manufacturing site developed to deter the Nazis( "if you drop anything on us we will give you double" ).... A person who lived in the area during that time described the situation. His father was a policeman at that time and when an incident within the plant occurred, releasing nerve gas into the area, his father went back in to save his buddies.... the three of them survived.... The person who recounted the story said his father was a large man who carried one man over his shoulder and dragged the other by the scuff of his neck - shirt - to safety

What other things have happened at the mouth of the San Gabriel River?

Originally uploaded by tardigrade.
... so, two days ago I was writing about my spider study at Mugu when I thought I heard a parrot 'gacking' outside my window. In Pasadena parrots fly in flocks east and west a couple of times a day. Some times I find a few flocks in trees near Old town Pasadena. And, I have heard that some flocks find the fruit of kaypoc trees

delicious...

I have had some sort of animal eat large holes in my oranges last year, and my pomegranates this year.... I thought it might be rats or birds like the blue jays.... but perhaps not. A flock of parrots flew by on Monday and then I heard a lone parrot next door.

The mocking birds were not too happy. You see, they "own" the tea tree"

and will follow me about as close as five feet away. When the parrot decided that the tea tree was a nice place to sit they chased it up into the liquidamber.



Well, it squaked and carried on until I hung my head outside (it was 92 degrees one Monday!!!!). "Yack!"I yelled, and then it listened. Back and forth I would make some horrible noise and the bird would return a scream. My neighbors already think I am nuts so I have no qualms about hanging out my window and acting like a fool.

Well, it is much cooler today and tonight, so, tomorrow I will put some seeds on the roof and see if it will come to the window.

It looks like a canary parrot, Brotogeris versicolurus chiriri

I had one that I bought from Sears long ago. I felt particularly alone one day and decided to visit the local pet store. Out in the back, with the potted plants, people were yelling and screaming, "It's over here!" "NO! NO! OUCH!!!" and then "DAM BIRD!" and"Can we kill it?!" Three adults with nets and ladders could not catch this feisty bird. For some reason I liked it. "I called up to them, "I'll take it!"

Well, that rallied the troops and they finally caught it after another half an hour. They were very happy to sell the monster to me at a greatly reduced price. He came home with me and was called, ''L'oiseau"

I found my new friend to like grapes. L'oiseau was not very big for a parrot, he was about 8 inches. I have seen large parrots consume grapes and I found that birds have a special capacity for eating them. The large parrots can eat up to 12 grapes before one of them is dejected out the other end. I found L'oiseau was a four grape parrot; one, two, three, four, five/poop, six/poop, seven/poop.... etc.

L'oiseau lived with me for 8 years. It was an adult when I bought him so I really don't know how old he was when I got him. I had a friend take care of him when I went on trips. He would try to be nice to him and L'oiseau would lure my friend to put his fingers in the cage just a bit too close and, "OUCH! IT'S PARROT POT PIE IF YOU ARE NOT CAREFUL!"

In the dead of winter, it was 82 degrees F... the sky was a beautiful blue without a cloud in sight. There was a soft off shore breeze perhaps 2-3 knots... if that... just to get the few tigers (who were out today) to fly more then five feet.

Up in the upper marsh of Mugu the pans were fairly slicked down from the rains from a month ago... was it a month? No! Strange weather!... The Halictidae burrows were mostly covered over by a thin crust of salt. This allowed the few tigers that were adults to come out to play. A few ladybird beetles flew here and there.

The Lycosidae snuck out from the safety of the Salicornia sp. and Frankenia sp. on the pannes and tried to blend with the back ground - they stood over cracks in the soil - to hide from the Pompilidae who were out hunting for fat spiders for their rookeries. My large (body 2 cm, legs 1.5 cm each) female, caught in September, lets me pet her legs - softly with a toothpick (their bite can become necrotic) and has not taken much food lately. She may be ready to mate.... in which case her wolf spider brothers and sisters in Mugu are in the same condition. A scary time for these creatures - ready do mating displays but, also a special time for the spider wasps, too.

The sun is very important to animals that cannot create the warmth they need for high energy tasks like foraging for food, hunting, mating, running from danger. Tigers bask in the sun so that they can become the fierce hunters we know and love. It is also a way to be able to escape their predators... like me or birds or spiders. Warming in the sun may also play a part in how well they out maneuver the fast flies that they eat, and may determine their rank the inter and intra species hierarchy, too.

The salt pannes are warm in the sun and the tigers find this very enjoyable. I found this Cicindela senilis frosti basking, turning this side and then the other side to the sun... then again turning its backside to the sun... a full rotation.

Most C. s. frosti caught and pinned in the Los Angeles Natural History Museum and the Santa Barbara Museum are grey with off white markings. The C. s. frosti that I have caught at Mugu come in grey, green, blue, and reddish colors. this one has it all. green, red here and there, and grey. Beautiful.

I feed him tiny crickets, flies, and occasional meal worm and cat food. He digs in the sand when it is cold and runs about when warm. He has a few hypopyl mites, one on his left eye.

California seems to be the land of Paradise to so many. Enough to make the streets and the highways hard to transverse even to go to a market .... and many things must be purchased in shopping malls which very quickly become like a backed-up sewer pipe. This is only one problem of 'Paradise' the other problem is getting things like water to so many people in a naturally dry environment.

Los Angeles was really several towns that grew together via the rails. There was a town at the beach, Santa Monica (still there), which was connected to a light rail which ran down San Vincenty and Santa Monica Boulevard from Downtown Los Angeles. Downtown was THE metropolis and was connected by rail to the Harbor, south, and then, east, out to the city of San Bernardino (my grandfather and his mother moved our here when his father died in Arizona - the town used to be called by the LA locals, "San Berdoo."). The cost of living got out of hand for the everyday citizens, and the City Fathers of LA needed more tax money (at that time the corruption issue in LA was blatant and outrageous) and so people began the ubiquitous suburbs that now choke the entire area.

The movie industry came here because we were so lawless (and immoral .... think about that as you watch the television today). And, just as WWII wound down, and not to ignore some other issues (see the movie Chinatown or watch my documentary - click on it to the right, it's free) folks from various backgrounds (many were either poor farmers or inmates from other state prisons) build the San Fernando Valley.

One has to understand that the San Fernando Valley, historically, was a swamp in some areas, and so today when it rains, the freeway fills with water. Before the homes were build (and all the good workers were taken back from hence they came - I met someone whose father was on one of the teams from jail in Utah) the area was farmland. My grandmother came to LA as a small child by railroad, to be with her grandmother who lived in the Adams District. My grandmother said she could smell the orange blossoms miles before she could see them by train. Fact is, Los Angeles and the surrounding counties have been giving up farming land to houses and such... even as I write this. But, one problem remains - water.

During the early fifties, the AAA and GM got together to get Los Angeles to give up their light rails for freeways and cars (their campaign was to get rid of the ugly electric wires for the clean electric cars that transversed the city so we could see the blue sky - but by 1960 smog eliminated that!!!). GM also invested in land in the Santa Monica Mountains and other areas to create more developments that needed more cars and freeways to get anywhere. And the three sources of water for all of Southern California; Owen's Valley, Sacramento River and the Colorado River, are all coming to their own 'tipping point' with the increases of the human population, climate change, and the need to pour concrete over everything.

There are many little details that go into this story, but I had to give a taste of things because as I drove through yet another area (Agora Hills in Ventura County, one of the fastest growing counties in the basin) that is being torn up for mini-mansions and such. I find stuff like this and I just can't believe it.

These people have just invested in a multi-million dollar home with automatic this and that... and yet no one is home ....in ALL of the possible definitions. It was chilly the last few nights, and the area can go below freezing, but these people have to have a perfect lawn. Icicles a foot long formed on the trees and the grass and the street and the sidewalk - !!!! everything where the sprinklers poured water, there was ice....!!!! sign.... And what didn't soak the lawn, or froze on the plants and cement, melted in the morning sun and ran down the drain out to the ocean.... only to be seen again in a few years, perhaps.... if we get enough rain.... or snow in the Sierra Nevada's a few hundred miles from here... or the Grand Canyon a thousand miles from here...

Testing the water in streams, rivers, lakes, and other water bodies has become quite an effort. Runoff, trash, illegal dumping point source pollution from industry damage our drinking water.

What these UCLA students are setting up is a prototype mechanized water tester.... It tests pH, DO, Nitrogen and Phosphorous. It also is a spectrophotometer that can identify the absorbence of the major components in the water.... identifying the algae populations by their chlorophyl.

Can you imagine automated water testers throughout California making sure the water is up to standard and the information broadcast to a main station somewhere....? sort of like wiretapping water before you tap the tapable tap.

It is amazing how many water ways in California are filled with trash and peoples' clothes. This particular stream in Ventura County is no exception. Last spring after the water receded from one of our most recent big storms, the up-rooted trees were filled with the branches of downed trees and festooned with trash, underwear, and t-shirts. Why?

Even after months past the big storm, this stream had been found to have a very high intestinal bacteria count. The main source of water of the stream was actually from a water treatment plant which must meet Federal Standards of water quality including low bacterial counts. So, why is this stream in such a bad way?

Well, If the underwear is any indication we may have an answer. Many water courses in Southern California have homeless people living along the banks. The intestinal bacteria... even though the upstream plant is releasing properly treated effluent, may come from the people who find shelter along the water courses.
