Everything is Related, Of and Part of the Whole: Beyond Inheritance, Our Ever-Mutating Cells and a New Understanding of Health and the Economics of Life

Leave a reply

 

One of my most current reads and the book that prompted this posting.When Darwin wrote “Origin of the Species” in 1859, he clarified and developed ideas that had been kicking around by those studying natural history and the origin of life, even the possibility of it’s evolution. Lamarck, von Humboldt, Darwin’s own grandfather, Haeckel and others had been speculating, arguing about certain pathways to ‘now’, but without having done that much serious research into life’s intricate relationships. There’s were less bold challenges or conceived theories. Christian orthodoxy shaped the thinking of the time, and opposing it, well that wasn’t done. Creation was pronounced a one time event, that all life forms that existed, had from the beginning by the grace and workings of God. But Darwin, himself a devout Christian, and Alfred Russel Wallace, did do the research, did examine the relationships in depth, adding their insights, the idea of ‘natural selection’, a process that ‘sorts’ through the accumulations of adaptations across a community and populations, ‘selecting’ those that give them a competitive advantage. These, over time would produce progeny at higher rates and would come to dominate a population and species. Since then one question led to another, as is the way of science. Where do these adaptations, these mutations, come from? How frequent are they? Aren’t our chromosomes ‘protected’ from this random degradation and mutation? Are mutations truly random? What drives them? Evolution ‘shows’ that over Earth’s 4.5 billion years, life has evolved towards greater complexity, organisms innovating new structures, variations and with it an increase in the sheer bulk of life, as more species create and fill more niches. Life on life. This can’t then be an entirely random event. Wouldn’t a truly random process result in no net ‘gain’? Wouldn’t it be a 50:50 proposition? One step forward, one step back? What is going on in this mutating?

Roxanne Khamsi, in “Beyond Inheritance”, takes the reader on a guided tour of our rapidly evolving understanding of the mutation of our cells and what it means. Mutation is an essential fact of life, one central to natural selection and the ongoing health of every living individual, and, perhaps our demise. Mutation, however, is commonly understood to be a negative, a degradation of the ideal held in our chromosomes. What’s going on here? Is it necessary or is it bad?
Mutation, it turns out, is pervasive. Every species, every tissue every cell and cell type is subject to it. We’re not talking about what occurs in ‘germ cells’, our egg and sperm,  those all important passers on of our genetic code. There are 30-40 trillion cells, in a mature human body, depending on our size, colonized by a like number of bacterial cells. These cells too, as they are going through a continuous process of metabolizing, internal and external maintenance, repairing and replacing themselves, are much more prone to mutation in this endless process of living. Some human brain cells are thought to survive over the course of our entire lives, but all of the rest, are being replaced at widely varying rates. Those epithelial cells of our intestinal lining are replaced every 3-4 days; we replace around 170,000,000,000, 170 billion red blood cells in our bodies, EVERYDAY. Every single cell replaced in our body, requires that the cell replicate its DNA, the two sets of chromosomes each containing 3.1 billion base pairs, the rungs in the helically shaped ladder of DNA’s structure. 3.1 billion base pairs, each consisting of a specific four ‘letter’ group of Adenine (A), Thymine (T), Guanine (G), and Cytosine (C), a 4 digit quarternary code….Perfect replication of each cell, billions and trillions of times over our lives…‘mistakes’, mutations happen. Organisms, cells, are not machines. We have this idea that machines can perfectly produce products endlessly, but that is wrong. Our continuous ‘cloning’ of our cells is far more precise a process. As the bumper sticker once so popular used to say, Shit happens…and the numbers within a complex, multi-celled animal such as ourselves, are astronomical. Mutations happen. We get stressed, sick, exposed to toxic substances, free radicals, physical trauma, various types of radiation, we age, become sedentary, our systems slow, we slow…as the necessary processes of life go on, within bodies and cells. Most must replicate themselves perfectly over our lives. Nevertheless, given the numbers, mutations accumulate. Some of these enable our continued ‘good’ health, some are benign, while others become ‘negative’ change agents, altering the operation and conditions within us, in what can be very harmful ways.

Dry Canyon Drought May 26: What’s Happening and What’s Our Role

Leave a reply

Taken May 17. Spare, limited growth, looking more like July than May. Dominated by the Gray, Ericameria nauseous and Green Rabbitbrushes, Chrysothamnos viscidiflorus..

We all know its been a drier and warmer than average Spring. In town people are often exclaiming about how wonderful its been, but in the Canyon the combination of dryness and unseasonable warmth are showing, if you know how and where to look. Dry Canyon has already taken on that ‘sere’ look, the soil and plants drying prematurely, annuals, the survivors that they are, seemingly knowingly rushing through their life cycles flowering at an earlier and shorter stage. The difference this year is subtle or maybe even unnoticed by many visitors. Whether you see it or not depends upon how many of the plants you know, where they should be and their ‘phenology’…what? Their growth schedule. Every plant species operates on its own internal ‘calendar’ when their seeds germinate, when those perennial growers ‘wake up’ and initiate spring growth, how they progress through the season, when they form their flower buds (and yes, grasses do flower, they just do so with flowers we don’t recognize, without petals, having other structures0, when their ‘fruits’ and seeds ripen.

Tree Planting Problems at Dry Canyon Village

Leave a reply

The reversion on this competing leader threatens to dominate the canopy if not removed. The planting appears good, straight trunk, well staked. It is always what is below ground, that is not readilly visible, that’s critical.

When I was still working for the city of Portland Parks, one of my jobs, for a number of years, was to do design reviews and construction inspection on big capital Parks projects being built from scratch downtown including South Waterfront, Caruthers, Jamison Square, Director’s Square,Tanner Springs and The Fields. I’d attend meetings with our project managers and the landscape architects, charged with assessing the appropriateness of their plant choices given their requirements, the site conditions, our capacity to provide the necessary maintenance over time, whether their combination presented conflicts, without commenting on the aesthetic of their designs, which was considered outside my expertise. Sometimes I was asked to do the same for projects in other areas. I’d visit the project sites regularly to observe prep work, planting and follow-up care, suggesting changes to the contractor and writing up my report. The architects generally approved, or rejected, the plant stock coming into a job, accepting or rejecting substitutions. It was my job to make sure that plants were properly cared for on site before planting, the prep appropriate, that they were planted properly and cared for over the first year of establishment.

The Nutrient Cycling Role of Fire in Central Oregon’s Arid Landscapes

Leave a reply

A Juniper like this one, growing out on BLM land around Cline Buttes, attains this squat and sturdy stature only after hundreds of years. Growing as they do on shallow, raised rocky areas, not only do they grow slowly, but there tendency is to caliper up. In irrigated pastures, these grow overly fast, spindly and upright. Look at that taper!

Ecologists will regularly claim that fire plays an essential role in the life and dynamics of the Juniper woodland, our sagebrush steppe and the grasslands of our arid and semi-arid plant communities, that without it, the landscape will deteriorate. Okay, but what does that mean? How can fire actually lead to a landscape’s improved vitality and diversity? What does fire actually do and what happens when it is eliminated? The short answer is that fire, in burning the collected fuels on the ground, breaks them down and returns them in nutrient form to the soil and the cycle of life. It provides the space necessary for a healthy and diverse landscape. To get there requires more thinking.

First some essential definitions and clarifications are needed: what are these ‘types’ of landscapes that together can be found in the arid reaches of Central Oregon; all landscapes are dynamic, evolving, changing over time according to the forces in effect on them, they are not static or fixed; what is meant by arid and semi-arid; fire, what is it, what is actually occurring when something ‘burns’; what is going on at a molecular level when an arid landscape burns; if this is so necessary, what fulfills this role in wetter landscapes; what’s the relationship between fire, rot and digestion; how, and does it, serve the nutrient availability and the necessities of organic growth. In understanding these basic parts we can better understand the self-renewing CYCLE of life as an ongoing process and how disruptions to it negatively influence its capacity to continue.

On Wilding and the Return of Nature: Thoughts on an Idea

Leave a reply

Talk of environmental crises is everywhere, climate change, mass species extinctions, losses of critical habitat, the privatization of once public resources and landscapes (and their subsequent ‘pillaging’ by corporate entities), critically dropping aquifers, what a chaotic climate may mean for world agriculture and our food supply, a world beset by an increasing rate of diseases and diminishing efficacy of the tools we have to combat and treat them….it is daunting and depressing. At the same time, generally barely mentioned in mainstream media, are notices of studies and ideas of what we can do to not just lessen these problems, quite a few of which are being implemented, but to repair the organic and global systems, whose faltering is leading to these increasing problems and potential catastrophes. To make head way on these is going to require a much more concerted effort by most of us. What, many are asking, can we do to usher in a return to a healthier, better functioning, world…before any looming system ‘course corrections’ do the ‘work’ themselves, eliminating the human problem, that ’we’ have collectively become. 

Isabella Tree’s, “Wilding: the Return of Nature to a British Farm”, which prompted this post, supports an approach in which mankind takes on a more responsive and respectful, while simultaneously, a less active role, in the management of the landscape. A ‘less active role’ because what she’s describing requires that we step back, relinquish some control, and allow the powers of nature to heal itself, stepping in where, when and how we must when those ‘forces’, diminished to the point where they are ineffectual, need the support…but no more. She calls for us to trust that our own evolved status is a product of the natural world, a potent nature with the inherent capacities and tendencies, to create, balance and heal, in like proportion to what it ‘takes’ and consumes; that we reclaim our ‘membership’, our historical relationship with this place and all of the life with which we share it. We are active agents of change and must, to the same extent, do the necessary work to heal those wounds, we’ve inflicted upon it through our economic demands and  industrial power. Her story here is one of a shared fate and a faith in life, which is illustrated time and again as she and her husband, Charlie Burrell, work to understand the land and life they are beginning to re-envision, more as curious students than confident ‘experts’. The process quickly becomes one of open discovery as they attempt to understand the health of the place they previously managed as a farm, with the economic expectations of a modern world that has itself become disengaged from life, seeing it narrowly in economic terms that had long ago been separated from ecological reality, limits. and the richness of a place.

Crossings: How Road Ecology is Shaping the Future of Our Planet, My Thoughts on Goldfarb’s Book

Leave a reply

Had I not read Ben Goldfarb’s 2018 book, “Eager”, I probably wouldn’t have picked this one up. Why would I want to read an entire book on ‘roadkill’? But I trusted him. And so I read it. 

I found his writing here crisp and engaging, like his other work, but I was still hesitant and did my reading in fits and starts. I’ve read several books lately about impending environmental crises and I didn’t really have the energy to do another, but I did finish it and found it a worthwhile and satisfying experience. Amongst these earlier books was Slaght’s, “Tiger’s Between Empires” which returned repeatedly to the problem of how devastating even the relatively little travelled roads of Russia’s remote Primorye Province are for its endangered population of Amur Tigers. In the world of ecology, roads routinely bring death to the wildlife they literally impact, as well as because of the discontinuities they create in the landscape, physical and chemical changes they visit upon the animal’s environment and the surrounding biotic communities. This is about the wholesale implementation of a technology ‘alien’ to the animal world, that purports to meet the ‘needs’ of humans while making little allowance for the uncounted species that reside alongside them.

Is a River Alive? On the Rights of Nature, an Adventure Story and a Shifting of the Dominant Paradigm

Leave a reply

Being a horticulturist, a student of ecology, evolution and all of the usual life science topics, my reading list is long with books I find and others recommended to me by friends. This most recent is one of the latter, “Is a River Alive?”, by British writer Robert MacFarlane. I hadn’t read any of his other books and my friend John thought I’d enjoy it…I did. I listened to it and, as it was read by MacFarlane himself, he added a bit of rhythm and emotion in his reading that would not have been there were I reading it in book form. This is particularly significant as you read the more emotionally driven sections, which, in this format, the ‘Canadian’ section, turns out to be a rollicking, adrenaline laced adventure story. 

While focusing on rivers, this is a book about the rights of nature, legal and otherwise. Why, does the growing community of such thinkers and activists, seem to think nature, in all of its forms, from fungi to mountains, rivers to oceans, the grandest to the most minuscule living species, deserve rights comparable to we humans? What makes them so special? MacFarlane and his compatriots, would turn that around, instead asking what makes we humans so special as to deserve that which we deny literally all others? Their only value, in how they serve us….The rights of nature proponents do not argue simply for their own favorite species or place, many of those so advocating, and protesting, come from thousands of years old indigenous traditions, peoples who have always recognized the links between all living things and those places and forces which permit and support them. And this isn’t because they are simple, backwards, savages or naive. Such thinking is not born out of the heads of green patriots, earth firsters and narrowly focused academics. This is a movement based on memory, connection, of those living in relationship with, in which respect for all things comes first, a world in which life is a gift, to be treasured…all lives, all species, all places, it is a remembering that no one individual, species or place is so special that any and all others may be sacrificed for its needs, its demands, its hungers.

Tigers Between Empires

Leave a reply

Three years ago I read Jonathan Slaght’s book, “Owl’s of the Eastern Ice’, a book that takes the reader into the inhospitable wilds of Russia’s Primorye Krai, the province immediately north of the Korean Peninsula, its multiple mountain ranges pushing up against the Sea of Japan. With a latitude the same as Oregon and Washington, its winters are far more severe. The book guides you through the mountains and snow, along with the researchers and conservationists, both Russian and American, studying the Blakiston’s Fish Owl, the world’s largest owl, and as the name implies, one that hunts fish in the region’s streams

.

I’ve just finished Slaght’s second book, “Tigers Between Empires: the Improbable Return of Great Cats to the Forests of Russia and China”. Set in the same rugged country, Slaght takes the reader along on a 30 year effort of study and conservation of the Amur Tiger, previously called the Siberian, a region they don’t exist in. You go with them tracking, setting snares next to scent trees, around kills the tigers are still feeding on, and narrow game trails the tigers prowl, as the researchers learn and refine their capture techniques along the way, sometimes at great danger to themselves as they attempt to capture one of the 200-500 pound cats. No one had ever done this before. Snaring, anesthetizing, weighing, measuring, assessing their health and attaching radio transmitter collars so the can track them across their ranges.

Nature’s Ghosts, Sophie Yeo’s Look into Ecology, the Loss of Species and Habitat, in a World that is more than mud, leaves and atoms.

Leave a reply

 

An ecological study tends to start with a particular species, a place or biotic community and then goes on to define it in terms of its relationships with its various members and the place itself, with its physical conditions. Sophie Yeo, the author of, “Nature’s Ghosts: the world we lost and how to bring it back”, does that, but where most of the books I’ve read take a narrower view and focus on a particular species or place, Yeo takes a both ‘local’ and a more global view as well as one that goes back deeply in time. Hers is not a book limited strictly to ecology as we generally understand it, because she is interested in it as a tool, a tool for reclaiming what has been lost, the ‘Ghosts’ of her title.

As a horticulturist, who took care of landscapes, this book has strong appeal, because not only does it look at life and all of its integral relationships, she includes us, the humans, who so often set ourselves separate in the rarified and an exceptional world of our own making. This is also a critique of this decision in which she writes to show us where and how we belong in this world, how we once were very much a part, how we behaved as a ‘keystone’ species, actors in a landscape, shapers, ‘creators’, and how now, as consumers/destroyers, because of our self ascribed position as superior beings, we became removed and exceptional, a threat to the our other community members, as we changed the world into one that allowed them less and less space. It’s a tall order, what she sets out to do here, but I think she largely succeeds and she does so in a way, with language that is almost lyrical, beautiful at times, and like a ‘bad’ scientist, introduces herself into her story, along with the emotion and clarity that being a new mother can give one’s self.  Continue reading →

Redmond’s Dry Canyon Firewise Management Plan, a Critique and Call to Action

Leave a reply

Those who follow such things know that I’ve been involved in the preservation and enhancement of Redmond’s Dry Canyon, joining with others to form the Friends of North Dry Canyon Natural Area as an advocacy group, working to educate the public about its qualities and fragility, while also providing ‘boots on the ground’ with clean up projects and the control of threatening Invasive plants. Most recently we’ve been supporting other groups and participating with a guided naturalist walk, a bat walk and a recent Botany and Birds, walk with the High Desert Chapter of the Oregon Native Plant Society and Queer as Flock, a bird watcher’s group. We’ve been advocating for better signage, a trails management plan and for increased efforts to control the illegal use of electric and gas powered motorcycles in the Canyon. Additionally we have be doing the Juniper survey work for the City, to help create a plant data base linked with the City’s GIS program to aid them/us in the development of an effective management plan for Dry Canyon. We’ve only been recently notified, along with the rest of the public, that the City has a new Dry Canyon Firewise Management Plan (a PDF is linked below), which we were assured included participation by foresters, local natural resource and conservation groups…yet, somehow, they’ve produced a one dimensional plan with the singular priority of eliminating the chances of a catastrophic fire, while ignoring virtually all other priorities!!!!
