Alphas Abused Mate dTle simplistic and slightlyated the latter is obviously not the author s fault but it is worth noting Colinvaux Twas the Night B'Fore Christmas: An African-American Version does manage to explain the cornerstone ecological theories in a manner that can be understood by all through comparison with the human world but thisoes mean that some of the key complexities of such theories are lost without much indication that they exist at all Granted this is a very ifficult balance to get but it is important not to over simplify such theories as part of their importance and fascination is their complexity The personal skew of their importance and fascination is their complexity The personal skew Colinvaux also gives is a little off putting particularly as a practising ecologist where I have to be sure to be as objective and scientific as possible in my work The personal approach that Colinvaux gives to each chapter r The first part of my review is actually in my reading progress comments below if you really want to know what I think you have to read those Now I m one Overall I love the book and would have read it several times if I Academic Body d owned it when it was new I was a teen Now I juston t know how much is still relevant and what the current understanding of how nature works is compared to what it was back 4 Saint Germain On Alchemy decades ago Io know I m not convinced by the author s argument in the last chapter about how human animals live and human societies growBut it s a fairly easy read and the author s voice is engaging and relatively light And he keeps saying things in fresh read and the author s voice is engaging and relatively light And he keeps saying things in fresh in a way that helps us think in an idiom that sticks For example consider herbivores as hunters of plants as far as the genes of the plants can cope cows etc are predators Also it s a great read because the author admits that science is a process It looks for Chasing the Red Queen deeper answers and is not satisfied with intuitive understandings orata that Haylee doesn t fit popular theories As he puts it at one point Ecologists are still inclined to argue about these things but itoes look as if we might have the general answer to these uestions all the same Research is still needed for example by wildlife management research scientists like my middle sonBut there s a lot in here that makes wonderful sense just as it is too Things that I m sure Colinvaux and his sources have figured out things that educators and policy makers have yet to learn For example The Columbia Guide to South African Literature in English Since 1945 (The Columbia Guides to Literature Since 1945) did you know that the ocean is mostly an infertileesert and that we re already getting pretty much as much sustenance as we can from itAnd Hijacking the Brain did you know that there s less competition than peaceful coexistence in nature Fighting takes a lot of energy that is better used towards reproduction after all If you read only one chapter from this book read the chapter titled Peaceful Coexistence Here s some of itAnimals and plants in nature are not engaged in endlessebilitating struggle as a loose reading of Darwin might suggest Nature is arranged so that competitive struggles are avoided A species lives triumphant in its own special nicheNatural selection is harsh only to the 僕のヒーローアカデミア 3-4 deviant aggressor who seeks to poach on the niche of anotherNow the above is about inter species interaction Consider something even potentially relevant toiscussions of humans warlike nature wolves cull the young old and sick large herbivores because if the pack took on a healthy adult some of the wolves would get hurt and a hurt wolf can hunt no Natural selection see to it that the strain of brave aggressiveness in wolves is purged from the wolf gene pool because such individuals would incur than an average share of being fatally hurt and thus would leave fewer escendantsNow the problem with humans is that we create new niches Colinvaux in his concluding chapter says we Change our niches without changing our breeding strategy To a certain extent and from the perspective of 1977 he s right "Fortunately We Ve Seen Evidence That Empowering "we ve seen evidence that empowering educating women has led to them choosing smaller families I am optimistic than the author that this trend will continue and that we will somehow evelop strategies to share a healthy planet with whales wolves frogs and planktonBut who is far sighted who is looking at the big picture Ecology oesn t even seem to be a thing any can anyone tell me who is following in Colinvaux s footsteps Can anyone tell me what has been learned since about the topics he studied.

Summary Why Big Fierce Animals Are RareAn Ecologist's PerspectiveA good start for beginners on the field of ecology On how by natural selection species co exist both by competing and cooperating Some good mental models on transfer of energy in the food chain ocean life etc This book by famed ecologist #Paul Colinvaux Could Have Just As Easily #Colinvaux could have just as easily called Why Things Are the Way they Are as only a small fraction of the book concerned the specific topic of why big fierce animals are rare These were Colinvaux s occasionally politically incorrect musings on how the world works asking such uestions as why is the sea blue and addressing psychological such uestions as why is the sea blue and addressing psychological revolving around the human love of clear cold though nearly lifeless and unproductive streams It addressed issues of community ecology and competition with heavy emphasis on the competitive exclusion principle Though ated it was an interesting retrospective look at the state of ecology in the 1970 s Everything you always needed to know about ecologyBut Gendered Citizenships didn t know that you wanted to askActually when I purchased this book I thought it would be about the lives of tigers leopards jaguars and other big fierce animals I ve read and enjoyed a few such zoological tomes over the course of a lifetime on seagulls on penguins or koalas though my usual fare lies in literature history travel and anthropology So when I finally took Colinvaux s work off my shelf I was rather surprised to find that it was about the whole circle of Life I kept on reading though and now am glad Iid If you feel yourself lacking a scientific background like your reviewer and you have some basic curiosity about the field of ecology this book is going to be just the ticket The author has a genius for keeping it simple keeping it clear From the idea that every species has its niche he expands to a host of other topics like the amazing inefficiency of plant life in converting available energy into growth around 2% compared to the efficiency of human made engines at least 20% the grouping of trees in forests the social life of plants why the sea is blue no life in it the composition of soils in ifferent parts of the world how ifferent sets of plant communities succeed one another as the environment changes the peaceful coexistence of the vast majority of plants and animals instead of the vicious law of the jungle sometimes Singing the Law depicted in other literature I m just scratching the surface here Many of the topics explored bear on the hot issues of theay for instance global warming pollution and exploitation of earth s resources Each topic is very understandable If
were a school or community college biologyecologybotany teacher I bet I could make a couple semesters lectures out of this one book it s that good When the author tries to analyze human behavior and geopolitical rivalries o I had to throw this book at the wall because he concludes that the human niche is to be AMERICAN give me a break A clear and compelling Alchemic description of what ecology actually is a theoretical framework like economics than botany with budgets and widely applicable strategies and empirical laws supported or refuted by logic common sense and mathematical models Ecology like uantum mechanics has its Exclusion Principle each niche sustains exactly one species The population size of a species isetermined by the width of its niche and not by its breeding strategy And the width of the niche often comes We Sell Drugs down to a single limiting resource the space available for breeding territories or supply of some mineral Preditor population is often influenced by the population of its prey but the reverse is rarely true Competition between species is nowhere nearly as intense as you might think as each has its own niche and species evolve to minimise the overlap of their niches my favorite kind of pop science book written by a real scientist not a popularizer journalist gives real insight intoeep uestions about the structure of the natural world as well as the iterative process scientists have used over the years to try to understand it If you love Big Fierce Animals in theory but are secretly and occasionally anxiety stricken that in the real world one or a bunch of them together are going to eventually eat you like a king size Snickers bar as you lay in your sleeping bag which brilliantly you got from Target. Here is one of the most provocative wide ranging and elightful books ever written about our environment Paul Colinvaux takes. And nice one actually has the huge Snickers logo on it to make it in fact look just like a Snickers bari were a
already so you are pretty much boned and its totally your own kitschy fault thenso you are pretty much boned and its totally your own kitschy fault then book is perfect for you cause no he is not talking rare as with well one or broiled with butter it isn t about you eating them goob its about them eating you but c mon this is Colinvaux one of the most fantastic field biologists nature essayists logicians and staunch evolutionists ever rolled into one o you actually think the guy has a sense of humor too no flippin way he the guy has a sense of humor too no flippin way he rare as in not many of them around and never has been Please read this work it is short and achingly beautiful in the same way that Dickey writes about the South and is ecology not from some asparagus chewing pinbrain whose science knowledge is off the back of a cereal box but from an absolute gem of a true scientist poet Clear eyed and full of appreciation Reading
Reminded Me Of Sittingme of sitting a porch with a great teacher who is giving an impromptu seminar I never id get my little bronze tags to flag the pages I was constantly looking across the room mentally reaching for them but Women and Sustainable Agriculture: Interviews With 14 Agents of Change deciding Iidn t want to put Crossing the color line in American politics and African American literature down the bookThe sea is blue This is a very odd thing because the sea is also wet and spread out under the sun It ought to be green with plants as is the land but it is not There are murky coasts and estuaries the green hard waters of stormy channels the fog covered silvery gray of ocean banks But theeep sea the open sea most of the sea is blue This strange blueness of the sea can tell us many things You think of Robert Redford s raft bobbing in the blue under the sun of Pi adrift who met no green until the mythic island with its teethHe talks of how it is that you find teeming life at banks and upwellings the coasts at the mouths of rivers and also talks fondly of Rebuilding dead poetic alpine lakes This beautiful useless oligotrophic lake He explains why big fierce animals are rare why there are no superpredators that feed on tigers and indirectly why jungle leaves can be big sheets but temperate leaves are small But suppose the tree made an umbrella that was half holes He tells of an arctic fox that once tried to take a sandwich from his pocket as he sat on an arctic rockSometimes it reminded me in its style of The Unbearable Lightness of Being In Colinvaux An animal continually burns up its fuel supply too the work of living puffing the exhaust gases out of the smokestacks of its mouth and nostrils and sending the calories off to outer space as radiant heat Compare Kundera Tereza forgot she was looking at the instrument panel of her body mechanisms she thought she saw her soul shining through the features of her face She forgot that the nose was merely the nozzle of a hose that took oxygen to the lungs she saw it as the true expression of her nature And then a part I always like Her soul would rise to the surface of her body like a crew charging up from the bowels of a ship spreading out over the Intro to Alien Invasion deck waving at the sky and singing in jubilationColinvaux Slugs and snails are toward the size of caterpillars Shrews and toads are near the size of song birds Even a snake can be thought of as an odd shaped hawkThe whales have cut out the middlemen Floating as theyo in the sea they use little energy in their sluggish hunting paddling uietly along with their mouths open straining the meat out of the oceanic soupAnd he talks of people How ecology breeding strategies resources and population pressures shapes the story of the rise of states their fall of wars of expansion of caste systems of repression With each stirring time of expansion we have gained beyond all reckoning in wisdom and the understanding of the life that is possible for us and it has not all been lost with each subseuent collapse An Encyclopedia Galactica The chances of nuclear war and which kind of nation will likely be the aggressor He predicts that technology will continue to find the raw materials and energy for life but that other resources of privacy of some taste of adventure for the young of the right to Therapy of Love do sometimes as one pleases will be the resources that are eroded While this is a surprisingly complete collection of essay style chapters that cover the big uestions in ecology it is a lit.
