tackling the Hegel problem on drugs

Hand reads...
As I write this, the La Selva experience is far away, mentally and geographically. I obsess over Garage Band, and my new found power (not ability, metal is all about power) to be done with artistic collaboration and create Plasmodium, a solo band composed of four bass guitars. My notebook is full of bass tabs. I have finally resolved to learn to play Black Sabbath's Iron Man. I am writing some fantasy. My wife and I make hot chocolate. I have rediscovered tea. I must remember that I lecture in a few moments. My world is frozen, urban, and dormant. This is not bad, just very far away.
The blurry frog is Dendrobates pumilo. They are very abundant at La Selva. My guide the first day described them as "happy" because it was raining so consistently, and they were mating.
The blurry flower is a banana plant, volunteer, a pest in Costa Rica. The Trigona bees are a very common species, whatever they are, and are robbing it of nectar. This species never really reproduces sexually, as far as I know, so this is a case of bees robbing a structure which is superfluous to the plant itself.
The bridge crosses the Rio Puerto Viejo, and divides the two halves of the La Selva compound. To get to the rainforest from lunch, or from where most people sleep, a person crosses it. It wobbles magnificently as foot traffic passes.
Super Liquorea Cisneros is along the highway to San Jose. A lot of Costa Rica looks just like that...logged, tropical, and with a strange aesthetic that has its own internal logic.
Thursday.
Lycaenidae. A messy howler monkey. A cricket nursing its brood. (I looked this one up, the genus was Anurogryllus, one of the few crickets that provides parental care. This genus is widely distributed in the Caribbean and Central America...the particular species was one of the flightless ones. It nursed a very large brood of nymphs under a rock, one of the only rocks I turned over while I was there). A great tinamou, the bees are attempting to rebuild their nest.
I was very excited about the discovery of a Trigona colony at Cuerva, the curve in the path to my cabin. Workers of a second species, black, possibly a halictid and possibly another Trigona, were entering and exiting all morning, unmolested. It looked like a case of commensalism. I shared my ideas with the staff here, prematurely. In the afternoon, guards of the more common, yellow species, were giving the intruders hell. Much repair was being done in and about the entrance tube. Still, it is a fine nest, inside a Naustitermes colony, and the process of sharing my completely erroneous idea brought me back to the gazebo in the botanical garden. I don't know how I missed it earlier, but nest boxes hang beneath its roof, three of the four are full of stingless bees. I stayed for a while, watching a cloud of workers of the common, small, species hover aloft in the sun as foragers returned from pollen runs. There was as second species, black, larger, building no nest-entrance tubes, and more sullen. Their guards sat motionless...all business. It had an interesting pronotal shield. I have no idea as to the identity of these two species, or the large banana-raider, or the medium-sized brown species in the fallen nest. I am not collecting specimens on this trip. They might not all be Trigona, even.
I saw my first snake this morning, after Lil'Hateful chastized me by email about being careless about walking about in the dark. It was small, brown, immature, probably about 14 inches long, and might have been elaphid. It looked like a dark brown garter snake. Could have been anything though, even a colubrid.
An impressive basilisk. Green Honeycreepers. Clay colored robin, woordcreepers, orioles, parasitoids. Going to miss this place.
Friday-12/21
Amegillia foragers at mid-tree stratum in morning, nests in banks, keystone pollinator, Trypoxylon present, another story here, is politum or leucotarsae (this species was the subject of my doctoral dissertation. The story is that politum, and the nests looked like politum nests, is not supposed to occur there. It was not T. monteverdeii, as far as I could tell, which is supposed to occur there). Was sad earlier, woke for birds.
Hand reads
Wren, white tail, woodpecker, mantis, striped anole, doves, unafraid bird (a black headed trogon), striped wren, a halictid, ground doves, other hummingbird, varigated squirrel, kingfisher, parrots, etc.

The Hippie was Eaten Alive Where He Meditated
There was a man who came here once, a hippie, who took to meditating in the forest. He was damn good at it, meditation that is. He sat on the wrong log, I guess, and the army ants found him. Within minutes, they reduced him to a skeleton. Earlier today, I think I saw his femur.
I stopped to take a piss in the river, and before I knew it, a Candiaru catfish was swimming up the stream of urine. Fuck. Somewhere out there, there are cannibals.
The plants above are growing on the corrugated tin roof of an "entrance" to a trail. I do not know how long they have taken to grow that size.
Maybe not. But I did something stupid today. Inspired by Jack Kerouac's rantings in Dharma Bums, I sat down on the trail and closed my eyes, listening. I wasn't exactly asleep, but close enough, and suddenly, there was Dimebag Darrel in my head, telling me I was an idiot. I opened my eyes. There were bullet ant foragers everywhere. I hadn't noticed them. Fucking hippie.
All day, I saw those whiptails. Also, slender anoles, and at least one ground anlole. Yesterday's lemur anole was not in the guidebook, presumably because it is a canopy species that should never have been on the ground in the first place. Birds' nest fungi, pale-billed wookdpeckers, making an awful racket.
My Trigona colony has finally posted a perimeter of workers around the entrance to their fallen home. I do not know whether they are capable of abandoning it by swarm, like Apis, or not.
So much of the tropical ecology I have been reading, for years, has turned out to be correct. This trip has been an astounding exercise in seeing things firsthand. The leaf litter is thin, and beneath it, red clay. Thin soil horizons and rapid decomposition everywhere, just like the textbooks teach. Light gaps full of regrowth. A surprisingly open canopy, however, not the midnight dark of Amazonia. Hurricanes, I hear, or read, fell the tall trees frequently enough so that regrowth is perpetual. Flowering is idiosyncratic, irregular, and intensely particular to the plant in question, as is fruiting. This also, I read in books. Termites really do construct tunnels over their foraging columns, and, also true, there are a great many leafcutter ants. With this maddening diversity comes a certain lack of abundance. I have seen a few parasitoids, but never more than one representative of a species. The biomass of a single common species of Trigona (I have that black one in mind, whatever it is) is probably greater than the combined biomass of all the Braconids out there, all fifty thousand of them. Trigona are so common that, drinking coffee in the morning, they land on my knee and investigate.
There are so many medium-sized leguminaceous trees here. I wonder if the productivity is actually as high as they say it is. If this is the case, the standing crop biomass does not represent it at all. Not exactly surprising, true. What seems to happen is that everything grows abundantly, and either falls over, is thrown to the ground by monkeys, or just kinda breaks off and disappears somewhere. These trees are built like Ikea furniture.

Tiene Jungle Rot
Already, it starts. Not just my feet, either. It has found my butt crack. It won't kill me. The Colorado Desert had this for me as well. My feet look like dead white jellyfish. It was wet boots that did it. Wet boots, and I sat on a wet bench this morning. Now, I need Tinactin spray desperately, and there is not a Walgreens for two thousand miles.
Today's catch was a huge clearwing butterfly. Amegilla sp. nesting in earthen banks. What little literature that exists on tropical pollinators seems to indicate that those bees are disproportionately important for allele flow because they trapline, rather than going straight home with their load and putting it to good use immediately Small butterflies, nymphalids, perhaps, defending a light gap in the old-growth rainforest. A distant view of a howler monkey. Many, many whiptails, all exuberant in the first real day of sun. The real sight was an tayra, I think. A fearsome weasel the size of a bobcat. It stood down the path from me, a little surprised.

A Strange Array of Unknowns
Tuesday, January 8, 2008
Some day, the trail will be the same, but the world will be different.....
The iguanas here are lazy. They lord over us from treetops, having nothing to do all day but digest fig leaves. The millipedes have sex all day. This occurs, day after day, nonstop. They bats do not know they are in imminent danger of extinction. They get right up in a person's face, regardless of any resemblance to Ozzy Osbourne. Poor vision. I did not bring any Slayer to see if it attracts them. Early experiments in California suggested this was the case.
I cannot get enough of walking through dark forests, stopping periodically to turn off my flashlight and loose myself in strange thoughts. The rain came down so thick that when I turned the light back on, there was a reflective sheet of water hiding me from the world. Better to use the moonlight to see on days like this. The fuzzy boundary between this world and the next blurs a great deal. One day, the trail will be the same, but the world will be different.
Parts of this place recall a dream I had, years ago, about Nepal, a place I have never visited elsewise. In my dream, which was so real I could hear monsoon rain clink thunderously against corrugated metal roofs, it was mostly dark and wet like this.
The best I can gather from repeatedly replaying the animations on geology websites, Central America was an island arc in the Pacific, off the coast of California, about 25 million years ago.
The cocos plate seems to have crammed them into their current position. Woe to the extinct South American megafauna. Strange Isthmus.

Lluvia mucho ahora
Monday Afternoon
Why doesn’t it rain indoors here? It seems like it should. The rain has rendered it obvious, now, at this soaking moment, that the Book of Genesis was written by desert nomads who simply could not comprehend large amounts of rain. Forty days and forty nights of continuous rain would produce what? Destruction?
No indeed.
Toucans.
Two species of the birds, and also, a rainforest full of toxic plants.
The logic is irrefutable. As hard as it rains, the water runs downhill. It goes somewhere else, down river and waterfall, past iguana and through gorge after gorge, taking every soluble nutrient with it. The nutrients are all locked in the plant life, just as I have been teaching every year.
Even if it pooled up, at a rate of eight inches a day/night, that would give 320 inches of freshwater. That depth of water would not inundate the globe unless the sphere were as flat as
Toxic trees, yes. These include various species of Virola tree, the dark red resin of which is full of DMT. Two species of toucan; the keel-billed Ramphastos sulfuratus, and the chestnut-mandibled Ramphastos swainsonii.
Dendrobatiid frogs (the red one, Dendrobates pumilio) calling restlessly for mates, the guide said that the rain made them “happy”, and affirmed that the tadpoles are indeed transported to bromeliads in the canopy. It seemed a crazy notion to me before. It makes sense now. There are bromeliads everywhere. A great Curasssow, idly strolling the pavement in the morning, a strange forest turkey called a crested guan, a coven of black Trigona bees robbing a banana flower, gold-headed tanagers, scarlet rumped tanagers, collared peccaries, bats sleeping in the shade of a wilted Heliconia leaf. The mouse-sized creatures had cut the veins to produce a rain-shade for themselves. Philodendron vines everywhere, strangler figs, the Mayan tree of god, the Ceiba, reaching between this world and the next.
Feral cocoa, leafcutter ants everywhere, lemur anoles, some gymopthalmid lizard, clearwing butterflies, Heliconia butterflies, owl butterflies, and a few things so strange I am wondering if they were real. That is the unmistakable impression I got, this morning, over coffee, looking at the birds. The gold hooded tanager, the green honeycreeper, and the scarlet-rumped tanager looked cartooney to my eye.
In fact, for the first time in several years, I do not need drugs. Perhaps they would be nice, after all. I have a feeling that any random tea made from that wall of green out there would either send me to my grave or have me sitting at the right hand of Aztec Elvis.
Bullet ants, Paraponera sp., unnamed ants and spiders, walking palms, mealy parrots, agoutis, howler monkeys, and mushrooms to mention except that some were ghost white doileys and others resembled little brown baseball bats.
An old stoner trick-If the washing machine is full, or too expensive-dry the clothes instead. Most of the unpleasant volatiles escape in the air. In fact, one washer was full, and the other accepts only alien currency. As I write this, lukewarm laundry cools on the bed. I stare at a pastiche of second-growth whatnot near the river. This morning, the guide told me that part of La Selva, near the Rio Puerto Viejo, used to be a Cocoa Plantation. Fungal disease wiped out the crop, year after year, taking most of
Birds and lizards nest alongside each other amid the clay banks of the trail. Like Vegas, the forest does not sleep, making me pause to budget my energy. I am about to go out alone.
Holy Christ! More cool birds. And another two, nearly sideswiping my head from behind as they flew by. The animals here seem either totally oblivious to humans (mating millipedes, Trigona) or nonchalantly curious. None of them look like they have ever seen a rifle. Or a jaguar.
More. What will my brain retain, and what will regress into that dark velvet land I visit as I sleep?
