On Biology, Ecology, Evolution: Health as a Product of an Engaged Life Aided by Science

Biology, the ‘life sciences’, botany, evolution, cell biology, ecology, health and disease, plant communities, our relationship as humans with each other, geology and the life around us, are all topics that interest me. My most recent reading choices have focused on embryology and an organism’s capacity to maintain homeostasis, what is meant by ‘health’. Earlier I focused on the big question of ‘What is life?’ I’m an integrator, an intuitor, an assembler of conceptual puzzles. For me understanding is the goal and that usually involves understanding the ‘pieces’ of the puzzle and fitting them together into coherent wholes. That’s what I do when I select books and read. While my fiction choices are relatively wide and varied, when it comes to this question, I am far more focused, purposeful. I am not overly concerned with being correct in terms of conventional thought or even regarding that which is accepted as being scientifically correct. I’m looking for what makes ‘sense’. I ‘test’ what I read.

Science is conservative and rightly so. It works to define a foundation from which we may build on. Many, if not all scientific advances, came at the expense and pain of researchers who reach beyond the established to address the problems that accepted theory has revealed as the process advances. Egos and careers can get crushed. Arguably, every significant advance in science began as a controversial idea. Over time, with repeated experimentation, advances in technologies that enable scientists to address questions not previously possible, new insights and ways to ask the ‘question’, the new gains support, or alternatively, is revealed to be ‘wrong’. In this process other questions arise, that move us toward a more complete ‘truth’, a truth that enlightening and revealing, can never be the ultimate answer. What preceded it was not necessarily ‘wrong’, but more likely incomplete, unable to fully explain the world as our understanding of it itself changes. Science becomes a process of understanding at an ever finer scale. What once served, still does, but in a coarser grained way. Occasionally, it demands a radical rethink of our basic understanding of reality. Continue reading

Holodiscus microphyllus, Rock Spiarea in Dry Canyon

Another less common slope dweller is Holodiscus microphyllus, or Bush Ocean Spray, a deceiving name, or Rock Spiarea, which is also somewhat confusing. Confusing because Spiarea is the genus name for an entirely different genera of shrubs. So I call it simply Holodiscus. ( Botanical names can be confounding to the uninitiated. I’m not a big user of mnemonics, but I still remember first learning this plant’s close relative, Holodiscus bicolor, and the phrase immediately came to mind, ‘Holy Discus, Batman!” I know, silly, but I doubt I will ever forget that plant.)

This typically occurs on the eastern flank of the Cascades and in the mountains of SE Oregon. The common name, ‘rock’, suggests its preferred sites. I’ve not seen one in Dry Canyon bottomland. It seems most common below the east rim north of the Maple Bridge. Continue reading

That Gray Stuff? It’s All Sagebrush…Nope

Part of the Dry Canyon plant series

Everybody knows Juniper and I suspect that a lot of people who think they know Sagebrush, that ubiquitous gray shrub you see everywhere, may be confusing it with other plants, blurring all ‘gray’ shrubs into one. Now this may not seem to be a big deal, but if you are trying to manage a landscape with these in them or trying to create a landscape which reflects the local plant communities, then it becomes much more important that you know what you have so that you can evaluate your landscape’s condition and decide upon what you may need to do, or stop doing, to meet your goals.

The Cut Leaf Thelypody in Dry Canyon

[Plants of the Dry Canyon Natural Area – This will be the start of a new series focused on the plants of Redmond’s Dry Canyon. I’m creating them to be posted for ‘local’ consumption on the Friends of North Dry Canyon Natural Area. It’s a City Park including about 166 acres at the north end of Dry Canyon Park which the City has identified as a Natural Preserve. The group works as an advocate with the City, on public education and helping with on the ground work projects. I’ll identify each such post here.]

As you walk the trails below the canyon rims you will be seeing these growing scattered and in bunches. This is the Cut Leaf Thelypody, Thelypodium lacinatum. These are common where ever there’s a bit of soil between the rocks on the slopes below the rims growing amongst the tumble of massive basalt. I’ve seen these elsewhere growing in other eastside Oregon canyons with similar conditions.
These are members of the Mustard family, prolific seed producers and quite competitive. Another plant that, at least so far, doesn’t venture out into the canyon’s bottomland.
Elegant when it first starts flowering, like so many native annuals and perennials, these start declining while they proceed through their flowering season detracting from their appearance. What do I mean…each spent flower, begins to form its narrow, linear, Mustard seed capsule, quickly maturing its tiny seed and then drying, twisting and browning, while the inflorescence continues to bloom out towards its terminal end. A little messy, yes, but characteristic of these plants. We humans are relatively intolerant of such decline in our garden plants and so generally refuse them admission. Under the local wild conditions, as dry as they are, species tend to either be early flowering, when soil moisture is still most available or those like this that begin to decline before the show is over. Summer drought is a ‘cruel’ taskmaster. There are exceptions to this rule but….

The Serviceberry: Abundance and Reciprocity in the Natural World, A Review

Robin Wall Kimmerer is a botanist, ecologist, a teacher and a member of the Potawatomi people of the Great Lakes region, from whom she learned her people’s particular world view, one once common amongst many indigenous peoples and in stark contrast to that of our present day dominant culture, which has lead us to powerfully shape our our world today. Her three popular books, “Gathering Moss”, “Braiding Sweetgrass” and her latest, “The Serviceberry”, present to the reader a glimpse into the natural world as seen from this ‘alternative’ world view. All three are enlightening reads and not overly technical. They are ‘invitations’ to see the world from a different perspective. The latest is the smallest, a book barely over 100 pages, with large type and in a small page format…a quick read, unless you pause to give what she presents some additional thought. The best, and the one I read first, is “Braiding Sweetgrass”.  Continue reading

Dry Canyon Proposal: the need for change in maintenance, use and planning

[The following is a piece I wrote and sent to our local Parks staff, its advisory citizens committee, mayor and city manager…I got little back in response. I’ve developed a relationship with one of the city arborists and the park’s planner as well as have met several active neighbors interested in protecting Dry Canyon’s natural areas, several of whom have natural resources backgrounds with agencies. The City has no natural resource or botanical staff. There is no formalized friends group, nor is their an outreach and public education program that addresses these problems and the role of residents in their solution. Signage is minimal and inadequate. Their horticultural expertise would also seem quite limited. This is understandable as the City’s population has grown very rapidly in recent years. The need for such programs and an increase in expertise on staff will only increase as Redmond’s population continues to grow.]

 

Redmond’s Dry Canyon looking south from the west rim on the Maple Street Bridge. The area in the immediate foreground burned this last summer.

A typical view at the base of a section of relatively unbroken rim on the east side.

The canyon floor is variable, but as this pic shows, a solid layer of hardened lava underlies what soil is here, either blown in or washed in, a limiting factor of what can grow here. Rabbitbrush is a common and ubiquitous native pioneer.

Match of the canyon floor is recovering from pasture use. These areas have relatively deep soils and are still transitioning with many weedy mustards, annual grasses like Cheat and planted grasses like Crested Wheat and Annual Barley. Native Bluebunch Wheat is scattered as are other natives. Gray Rabbitbrush, a native seral species has moved into much of it, but the weeds are dominant. Sagebrush and Bitterbrush are more at the edges and lower rim areas.

This section of bottomland, former pasture, probably burned not that long ago, has quite a colony of Rabbitbrush coming along, all it would appear of even age, suggesting a fire. Rabbitbrush are early colonizers and ‘prepare’ the way for natives to follow. This is just north of the Maple Bridge.

This area, maybe 5 acres, burned in July. It will be interesting to see what comes back and what the City may plant??? Fire kills Sagebrush and Juniper, while it seems to favor Cheatgrass. So far, April ’24, nothing has been replanted. The window for seeding is closed. Rabbitbrush can survive a burn. This site is unfenced, with very fragile soils and we’ve already observed new bike trails in it.

My wife and I are both recent returnees to Central Oregon having both grown up here. We are also frequent walkers in Dry Canyon, a place I spent many hours in playing and exploring as a kid in the 60’s. Redmond has changed a lot over the intervening years…change that continues apace as it grows. I’m not going to whine about the ‘good old days’ and things lost. Much of the change I welcome or at least accept (We did move back!), but population growth, in addition to bringing along economic vitality and stability, new and enriching opportunities and a more diverse community, increases the ‘pressures’ on the naturally limited assets that largely define the place and attract residents. I’m speaking here of the natural landscape, its features and the opportunities which it affords us for recreation and quiet enjoyment. Realtors were once fond of saying that no one is making new land, as a prompt for buying…it is a fixed and limited quantity. This limitation has profound implications for a growing population. We have far more people today ‘enjoying’ a limited, and increasingly over utilized landscape. Continue reading

The Way of the Cell: Molecules, Organisms and the Order of Life – A Review (Read This Book if any of the Life Sciences are of even remote interest to you)

I’m an integrator, a contextual learner and a big picture kind of guy. I am willing to ‘slog’ through the details, the analyses of experts, to understand what is going on, when the details help me understand, in this case, the operation or ‘life’ of the whole organism. What are the processes, how do they influence one another and how does that result in the condition we recognize as the dynamic, animated phenomenon of living. Franklin Harold, a professor emeritus in biochemistry at Colorado State University when he wrote, “The Way of the Cell: Molecules, Organisms and the Order of Life”, in 2003, has produced the ‘best’, and most comprehensible, review I’ve found of the life in the cell, to date. This book does not require an advanced degree to follow. It requires an interest in biology. A botanist, horticulturist or even avid gardener pursuing a more thorough understanding of what life is and what is occurring within the plants and animals around will find much that is accessible to them here. This book is not a slog. It is readable and readily comprehensible, though for those with less of a science background, a little more challenging, but hey, nothing ventured, nothing gained. The jargon he uses I would say is necessary. Science can be very precise in how it views its subject, necessarily so, because meaning becomes lost when the precision of language is too generalized. I’m adding it to my own library. I include some extensive quotes here to give you a sense of his style and philosophy. I also gleaned much from these particular passages. In school I endured too many professors and lecturers who seemed more interested in impressing their students with their own brilliance, and our inferiority, and came to relish those who were true teachers, who were able to impart to their students, there own love and fascination with their topic. Harold is one of these. He set out to write a book that would reach out to the reader making his topic more accessible, more comprehensible and thus widen the circle of understanding…and he has succeeded.

The cell, scientists would agree, is the smallest fully functional unit of an organism, any organism. It is the basic structural unit that has been joined together to create larger, more complex organisms. If you attempt to reduce it any further, divide it into its component parts, which science typically does in its process of reduction to understand it in its parts, it loses functionality and dies. Single celled organisms, bacteria, archae, and the larger single celled eukaryotic organisms, like amoebas, comprise the majority of living species on earth, by both number of species and by sheer mass. They are as complete as any single organism, like ourselves, a Redwood or Blue Whale, can be. Whether a single celled organism or a massive multi celled organism made up of several billions of many thousand ‘types’ of different specialized cells, almost all cells are capable of all of their essential functions, as long as they are supplied with proper nutrients and flows of energy. Cells, as Harold describes them, are highly coordinated ‘societies’ comprised of many millions of individual proteins, enzymes, lipids and ions, with various forms of RNA, bound within a protective, limiting and self-regulating membrane, often with other internal membranes, which protect and allow other more specialized functions within the cell…and DNA, or in the cases of some bacteria, RNA, which contain the ‘code’ which prescribes the organism. It is within the cell membrane where the particular mixes of their constituent parts are held in dynamic flux, where the ‘work’ of living occurs. Within what was once described as a ‘soup’ of chemicals, suspended within a virtual sea of water, the cell conducts the ‘business’ of life. Today we understand that within a single cell water molecules far out number any other substance. Cells possess a complex internal structure, a cytoskeleton, grown from proteins, that is integral to the transport of metabolites, the regulation of its thousands of internal processes, the structure of the cell itself and essential to its ability to respond and move. The actions within the cell are largely self-regulating, influenced, certainly, by outside, and internal energy gradients. The various reactions influence the rate of other reactions in a complex system of feedback loops, with a ‘logic’ often compared to that utilized by a computer. Processes are chemical, electrical and ‘mechanical’ as one reaction induces a conformational change, a change in ‘shape’, of a particular protein or enzyme, which directly influences what it can do. These changes in ‘shape’ act as effective ‘switches’ within the cell, switches operating amongst thousands of other such switches, creating an intricate system of feedback loops which regulate just what the next step will be. Only functions tend not to be linear. They can be extremely complex, with a redundancy that also allows the cell to vary internally widely, while maintaining itself, overall, in a relatively stable state. Its internal complexity then accounts for its responsiveness and adaptability. It imparts a degree of flexibility, of adaptability to a system within the cell. All of this going on at a molecular level that plays out, with powerful effect, at the organismic level. Continue reading

Every Life is on Fire: How Thermodynamics Explains the Origins of Living Things–A Review…and a Deeper Look Into the ‘Fire’ of Life..

This is a book about ‘life’, that which animates particular organic structures, organisms, while other, non-living, ‘structures’ remain fixed, but for the physical and chemical forces which wear them down. From our human perspective, this sets ourselves, and all other living things, apart from the inert, nonliving, matter that comprises our world and the universe. England, as a physicist, sees the world of nature and all matter within it, differently than most of us. Science has demonstrated that the universe tends to operates under consistent ‘laws’. Organisms, while a special ‘class’ of matter, are still ‘of’ matter, composed of the same atoms, only joined together in complex macromolecules not found outside of organisms, created wholly within organisms. They are a ‘family’ of complex, shared, organic structures. This complexity of structure goes to determining their functionality. Function increases and diversifies as complexity increases. Capacities are expanded with the flow of energy through them, an effective and sustaining agent in their ‘being’ and evolution. England’s view is consistent with the many other physicists who have looked into life and view it as an inevitable outcome of the processes, energies and materials that comprise Earth’s particular corner of the universe. Earth appears to be a relatively rare occurrence, but it is extremely doubtful that it is a singular one. The ‘ability’ of energy to organize and structure matter is universal. Given the particular mix of ‘ingredients’ and energies here on Earth, matter has come together over the course of over 4 billion years to form life as we know it, because it could, and whatever is possible/probable tends to happen with a degree of frequency. Particular patterns precede those to follow, not necessarily determining them, but increasing the likelihood that they will. The flow of energy through matter tends to ‘favor’ a range of outcomes. Those outcomes tend to favor the next, building from one ‘success’ to the next.


These patterns and energy flows occur at subatomic to molecular levels, well below our ability to observe and measure them. We can only directly observe the ‘results’. The underlying patterns are not generally obvious to us.  Our perceptions are shaped by our the physical limitations of our sense organs and our beliefs about the world. We tend to ‘see’ what we expect to see, not necessarily what is there. We shape our perceived world into the commonly shared story that has been passed on to us, a very human story. Our particular indoctrination, our educations, all go toward determining what we see, how we interpret it, and then taking our experience, we use it to reinforce that understanding. In a sense we ‘choose’ and make our reality. From the moment we each open our mouths or put word to page, we do this. Our language and knowledge limit us. It requires that we distill our perceptions, our experiences and our understanding into a comprehensible form. We are all at a ‘remove’ in this sense, apart from the world in which we live, although we are intimately immersed in it. And that is the source of much of our difficulty, for like fish swimming in a stream, we are ‘of’ this place, a part trying to understand its extended self, our boundaries, self-imposed, insistent upon our individuality and our misunderstanding of what that means in a world that fully integrated and interwoven.

As ‘western’ people we tend to see ourselves as separate from it. Independent agents. When in actuality, we can never be so. To be so independent, separate, would negate that which is essential to our lives, the flux and flow of energies through us, as parts of a larger, complex and whole system. England looks into this question of what life is by taking our modern and still developing theories of ‘thermodynamics’, our study of energy and the way that it ‘works’ on the stuff of the universe, on matter, as his way into this ‘story’. Energy is transformative. Matter, is arguably, a particular expression of energy. One can be translated into the other.


England is a theoretical physicist. You will not find in this book a detailed explanation of the living organism or description of the flow of energy through one. That is within the purview of the cell biologist, the biochemist, the quantum biologist. Thermodynamics, and his understanding of dissipative adaptation are larger concepts that can give us a framework for understanding the bigger picture of an almost unfathomably complex topic. England joins with those today who would argue that any living organism is not so much a thing as it is a process, in a state of continuous change, a process which both follows a probable, understandable, path, and is itself a part of the larger/longer process of evolution, of becoming, building on itself and life’s many patterns, as it moves ahead through time toward something unknowable to us. We exist from moment to moment, a ‘response’. Fall out of that moment and we are dead. Through us, the flux and flow of matter and energy, drive an organism, along a path, a path that follows one of a particular and massive set of more or less likely probabilities, each which influences what will follow, within a universe of definable ‘law’. Here England gives us an intellectual framework for understanding the processes at play in this process of living. Living organisms are conductors of a continuous flow of energy through themselves, from outside and back, after it has degraded. This flow of energy acts in very particular ways on the molecules, cells, tissues and organs of an organism…until it no longer can. An organism, is in a sense, a conductor, a channel through which energy flows from a higher, more available state, to a lower, less available state. Energy drives them, permits them and enables them, so that they are in this sense ‘self’ sustaining…as long as the energy flows and the organism can maintain the integrity of its structure at all levels.


The following is an extensive quote from his book: Every Life is on Fire: How Thermodynamics Explains the Origins of Living Organisms, pp. 113-116.


“…a plant—for example—has to be thought of as holding steady on a steep [energy] hillside in a constant state of free fall. Much like the chemicals in a battery powering a flashlight, many molecules in a plant are constantly undergoing reactions that convert them into other, lower-energy forms. At the same time, randomizing thermal fluctuations are taking the specially ordered components of each cell that have been assembled in a particular fashion and wreaking havoc with them, either through chemical damage or via larger-scale physical rearrangements. In permanent darkness, a plant is therefore on a slow road to death, for dying in physical terms is nothing more than sliding downhill in a variety of chemical and physical ways. Of course, plants can survive just fine for a while in the dark, but not forever. [Animals, for the most part exist in a much more precarious balance requiring much higher energy flows for a given mass.] Eventually, the twin tendencies to lower energy and higher disorder that are required by the fall to thermal equilibrium will win out, and the pile of matter that was originally a live organism will start to look less and less like one.

Musella lasiocarpa: An Adaptable, Smaller Banana for Warm to Mild Temperate Gardens

I’ve been growing Musella in a larger pot as well. It performs much as it does in the ground reaching similar size, getting along with comparatively little water. This plant suffered no leaf scorch even during our record breaking streak of 108º, 110º and 116º in late June ’21. It was protected in shade in the afternoon. Here it sits on the deck next to my Musa accuminata ‘Zebrina’, a Malaysian tropical, which did suffer a lot of marginal leaf burn, losing several of its softer, newer, leaves, even with daily watering of its pot during the hottest stretch (It quickly recovered after the temps settled down.).

Musella lasiocarpa may be the most easily recognized of the 48 species within the small but economically important Banana family, Musaceae. It is distinguished from all others by its small size, its congested, quickly tapering pseudo-stem, which is nearly bulbous at its base, its leaf blades extending upward from its relatively long petioles, shaped much like the traditional blades of Aleut kayak paddles and its unique flowering structure. Like all bananas the pseudo-stem is made up of tightly clasping, channeled, petioles, and its inflorescence which resembles a golden lotus flower in bud, with tightly held yellow to orange bracts having very little separation from one to the next, shielding its later emerging flowers tightly held beneath.  The shape of this plant and its texture lies somewhere between the more commonly grown ,and proven, hardy members of its Order Zingiberales, the Hedychium spp. and both Musa Basjoo and Musa sikkimensis, which often fill a role in providing many mild to cool temperate gardens with their ‘tropicalesque’ characteristics. If your garden resides in climatically colder areas than those experienced by topical plants in the wild, then any of these may succeed as permanent contributors to a tropical ‘feel’ in your garden. Of course you can also choose to grow true tropical and subtropical species if you are committed to the necessary protections they will require over your cold season. Continue reading

“Entangled Life: How Fungi Make our Worlds, Change our Minds & Shape our Futures”: A Review

Sheldrake, Melvin, “Entangled Life: How Fungi Make our Worlds, Change our Minds & Shape our Futures”, Random House, 2020.

I have spent most of my life outside amongst, growing, observing or studying plants and yet, every page here has caused me to take at least a moment to reconsider the life I’ve been so involved with. Everything here underscores what I’ve read and learned elsewhere, sometimes casting it in an entirely different ‘light’. While we learn to think of organisms as discrete individuals, fungi, a class of organism separate from the bacteria, plants, animals, even viruses which I’ve been examining, are impossible to consider on their own without looking into their vital relationships with the other forms of life.  While all organisms depend in many ways, great and small, upon other organisms for their support and sustenance, fungi are nearly impossible to imagine separately, their ‘bodies’ being literally intertwined in and around those of others.

Relatively early in the book, Sheldrake describes the difference between fungi and animals in this way, animals put food into their own bodies, fungi put their bodies in their food, digesting what they require by secreting acids and then drawing the broken down nutrients back into their mycelial bodies and transporting them to where needed. Continue reading
