Book Fact Friday – Lady Beetles

From chapter 11 of Garden Insects of North America:

Most lady beetles lay between 5 and 30 orange-yellow eggs at a time. They are distinctive, but may sometimes resemble those of leaf beetles. Eggs are laid near colonies of insects to provide food for the larvae.

Garden Insects of North America by Whitney Cranshaw

Garden Insects of North America is the most comprehensive and user-friendly guide to the common insects and mites affecting yard and garden plants in North America. In a manner no previous book has come close to achieving, through full-color photos and concise, clear, scientifically accurate text, it describes the vast majority of species associated with shade trees and shrubs, turfgrass, flowers and ornamental plants, vegetables, and fruits—1,420 of them, including crickets, katydids, fruit flies, mealybugs, moths, maggots, borers, aphids, ants, bees, and many, many more. For particularly abundant bugs adept at damaging garden plants, management tips are also included. Covering all of the continental United States and Canada, this is the definitive one-volume resource for amateur gardeners, insect lovers, and professional entomologists alike.

To ease identification, the book is organized by plant area affected (e.g., foliage, flowers, stems) and within that, by taxa. Close to a third of the species are primarily leaf chewers, with about the same number of sap suckers. Multiple photos of various life stages and typical plant symptoms are included for key species. The text, on the facing page, provides basic information on host plants, characteristic damage caused to plants, distribution, life history, habits, and, where necessary, how to keep “pests” in check–in short, the essentials to better understanding, appreciating, and tolerating these creatures.

Whether managing, studying, or simply observing insects, identification is the first step–and this book is the key. With it in hand, the marvelous microcosm right outside the house finally comes fully into view.

• Describes more than 1,400 species–twice as many as in any other field guide
• Full-color photos for most species–more than five times the number in most comparable guides
• Up-to-date pest management tips
• Organized by plant area affected and by taxa for easy identification
• Covers the continental United States and Canada
• Provides species level treatment of all insects and mites important to gardens
• Illustrates all life stages of key garden insects and commonly associated plant injuries
• Concise, clear, scientifically accurate text
• Comprehensive and user-friendly

#MammothMonday: PUP’s pups sound off on How to Clone a Mammoth

The idea of cloning a mammoth, the science of which is explored in evolutionary biologist and “ancient DNA expert” Beth Shapiro’s new book, How to Clone a Mammoth, is the subject of considerable debate. One can only imagine what the animal kingdom would think of such an undertaking, but wonder no more. PUP staffers were feeling “punny” enough to ask their best friends:

 

Chester reads shapiro

Chester can’t get past “ice age bones”.

 

Buddy reads shapiro

Buddy thinks passenger pigeons would be so much more civilized… and fun to chase.

 

Tux reads shapiro

Tux always wanted to be an evolutionary biologist…

 

Stella reads Shapiro

Stella thinks 240 pages on a glorified elephant is a little excessive. Take her for a walk.

 

Murphy reads shapiro

A mammoth weighs how much?! Don’t worry, Murphy. The tundra is a long way from New Jersey.

 

Glad we got that out of our systems. Check out a series of original videos on cloning from How to Clone a Mammoth author Beth Shapiro here.

In today’s #MammothMonday exclusive video, Beth Shapiro, author of How to Clone a Mammoth: The Science of De-extinction, raises big questions about cloning technology and explains how she feels this controversial technology should be used.

You can also listen to Shapiro’s interview on NPR from this past weekend, where she discussed the motivations for bringing back an extinct species, along with some of the specific risks involved with releasing genetically engineered elephants into the wild.

#MammothMonday: How Does the Science of De-Extinction Work?

02aVerso_shapiro_plate blog

Happy #MammothMonday! Today, Beth Shapiro clarifies the science of de-extinction. As she explains, if scientists possess a tiny bit of living tissue from a species that has gone extinct recently, they can bring back that animal through traditional means. However, if the species has been extinct for millions of years and there is no living tissue, the process of bringing the animal back to life is far more difficult. Beth had a terrific piece in the Chronicle of Higher Education recently that offers much more info, and geneticists have been sounding off on the discussion as well. Check out today’s original video:

Just days ago, scientists were finally successful in sequencing the full mammoth genome. Beth Shapiro, author of How to Clone a Mammoth offered commentary on this exciting and ethically controversial achievement. According to the BBC News, “A US team is already attempting to study the animals’ characteristics by inserting mammoth genes into elephant stem cells.”

For today’s #MammothMonday, Beth Shapiro expresses her doubts and concerns about bringing back the passenger pigeon, pointing out the unique difficulties involved in cloning a bird. Learn more about Shapiro’s reasoning in the video below.

Math Drives Careers: Author Louis Gross

Gross jacketLouis Gross, distinguished professor in the departments of ecology, evolutionary biology, and mathematics at the University of Tennessee, is the author, along with Erin Bodine and Suzanne Lenhart, of Mathematics for the Life Sciences. For our third installment in the Math Awareness Month series, Gross writes on the role mathematics and rational consideration have played in his career, and in his relationship with his wife, a poet.

Math as a Career-builder and Relationship-broker

My wife is a poet. We approach most any issue with very different perspectives. In an art gallery, she sees a painting from an emotional level, while I focus on the methods the artist used to create the piece. As with any long-term relationship, after many years together we have learned to appreciate the other’s viewpoint and while I would never claim to be a poet, I have helped her on occasion to try out different phrasings of lines to bring out the music. In the reverse situation, the searching questions she asks me about the natural world (do deer really lose their antlers every year – isn’t this horribly wasteful?) force me to consider ways to explain complex scientific ideas in metaphor. As the way I approach science is heavily quantitative, with much of my formal education being in mathematics, this is particularly difficult without resorting to ways of thought that to me are second nature.

The challenges in explaining how quantitative approaches are critical to science, and that science advances in part through better and better ways to apply mathematics to the responses of systems we observe around us, arise throughout education, but are particularly difficult for those without a strong quantitative bent. An example may be helpful. One of the central approaches in science is building and using models – these can be physical ones such as model airplanes, they can be model systems such as an aquarium or they can be phrased in mathematics or computer code. The process of building models and the theories that ultimately arise from collections of models, is painstaking and iterative. Yet each of us build and apply models all the time. Think of the last time you entered a supermarket or a large store with multiple checkout-lines. How did you decide what line to choose? Was it based on how many customers were in each line, how many items they had to purchase, or whether they were paying with a check or credit card? Did you take account of your previous experience with that check-out clerk if you had it, or your experience with using self-checkout at that store? Was the criterion you used some aspect of ease of use, or how quickly you would get through the line? Or was it something else such as how cute the clerk was?

As the check-out line example illustrates, your decision about what is “best” for you depends on many factors, some of which might be quite personal. Yet somehow, store managers need to decide how many clerks are needed at each time and how to allocate their effort between check-out lines and their other possible responsibilities such as stocking shelves. Managers who are better able to meet the needs of customers, so they don’t get disgusted with long lines and decide not to return to that store, while restraining the costs of operation, will likely be rewarded. There is an entire field, heavily mathematical, that has been developed to better manage this situation. The jargon term is “queuing models” after the more typically British term for a waiting line. There is even a formal mathematical way of thinking about “bad luck” in this situation, e.g. choosing a line that results in a much longer time to be checked out than a different line would have.

While knowing that the math exists to help decide on optimal allocation of employee effort in a store will not help you in your decision, the approach of considering options, deciding upon your criteria and taking data (e.g. observations of the length of each line) to guide your decision is one that might serve you well independent of your career. This is one reason why many “self-help” methods involve making lists. Such lists assist you in deciding what factors (in math we call these variables) matter to you, how to weight the importance of each factor (we call these parameters in modeling) and what your objective might be (costs and benefits in an economic sense). This process of rational consideration of alternative options may assist you in many aspects of everyday life, including not just minor decisions of what check-out line to go into, but major ones such as what kind of car or home to purchase, what field to major in and even who to marry! While I can’t claim to have followed a formal mathematical approach in deciding on the latter, I have found it helpful throughout my marriage to use an informal approach to decision making. I encourage you to do so as well.

#MammothMonday: What to Bring Back?

How to Clone a Mammoth

Welcome to another #MammothMonday. Beth Shapiro, author of How to Clone a Mammoth, was recently called by Brian Switek of National Geographic, “the perfect guide to the ongoing discussion about de-extinction.” Today, she continues in that role, answering the question, “What to Bring Back?” In this fascinating video, Beth discusses the thinking behind the decision to bring back a large mammal as opposed to passenger pigeons.

What do you think about the debate around cloning mammoths?

Presenting the New Trailer for Beth Shapiro’s “How to Clone a Mammoth”

Should we clone extinct animals? Evolutionary biologist and “ancient DNA” researcher Beth Shapiro’s highly anticipated How to Clone a Mammoth: The Science of De-Extinction takes apart an idea that not so long ago seemed more fiction than science. Now, several teams of researchers are working to reconstruct the mammoth genome. How to Clone a Mammoth is making its debut with an array of coverage, including a feature in yesterday’s Sunday Times. From the article:

What excites some scientists, and disturbs others, is that the genome could one day become a template to recreate real mammoths — or something like them.
In her new book, How To Clone a Mammoth, Beth Shapiro of the University of California, an expert on ancient DNA, said: “If we really want to bring mammoths back to life, then we’re in luck, as far as DNA preservation goes. Some mammoths lived in places where their bones and carcasses were buried in permafrost, like being stuck in a freezer for 30,000-plus years.
“It’s in pretty shoddy condition, so hard to piece together, but if we sort through these tiny pieces, finding where they fit along the elephant genome, then we can slowly build a lot of the mammoth genome.”

We are delighted to share the book’s wonderful new trailer:

 

Q&A with Ian Morris, author of Foragers, Farmers, and Fossil Fuels: How Human Values Evolve

Princeton University Press recently had the opportunity to talk with Ian Morris about his new book, Foragers, Farmers, and Fossil Fuels: How Human Values Evolve.

Foragers, Farmers, and Fossil Fuels

In your book you look at the evolution of human values over tens of thousands of years. Can you briefly say why and how values change? Isn’t morality universal and unchanging?

The answer to the last part of this question is easy: yes and no. I say yes because in one sense, morality certainly is universal and unchanging. Our human values are the outcome of millions of years of evolution. Animals that were born with genes that predisposed them to value fairness, love, honor, decency, and a host of related virtues tended to flourish, while animals that did not value fairness, etc., tended not to flourish. As a result, a disposition toward these prosocial attitudes spread through the gene pool, and almost all humans share these same core values. The reason I also say no, though, is because the ways people have interpreted fairness, etc., have varied wildly through time. Few historians dispute this; but fewer still have seen that what causes values to change is not the deep thoughts of philosophers but the most basic force of all–energy. As humanity has moved from foraging through farming to fossil-fuel use, we have found that different levels of energy capture call for different kinds of social organization, and that these different kinds of organization favor very different interpretations of human values. To foragers, fairness often means that everyone should receive equal shares of food, respect, and other good things, but to people in farming society, fairness often means that people should receive very different shares, because they are felt to deserve different shares. Men deserve more than women, the rich deserve more than the poor, the free deserve more than the enslaved, and so on through too many categories to count. Foragers and farmers feel the ways they do not because the former are all saints and the latter all sinners, but because it would be almost impossible to run a foraging society like a feudal monarchy and almost impossible to run a farming society as a band of equals. Foragers who lean toward equality and farmers who lean toward hierarchy itend to outperform and replace foragers and farmers who do not. In our own age of fossil fuels, values have continued to mutate. We tend to believe that fairness means that everyone should receive somewhat equal–but not too equal–shares of food, respect, and other good things. Anthropologists who spend time in foraging or farming societies often feel as if they have stepped into alien worlds, where values are upside-down; and people from most periods in the past would have felt exactly the same way about us.

In our current Fossil Fuel age of values, you argue that violence and inequality have diminished greatly from past periods. That seems very counter-intuitive. Can you elaborate?

A lot of people today are nostalgic for a simpler, vanished, preindustrial world, and there are ways in which they are right to be so; but not if they value peace, prosperity, or (on the whole) equality. Across the last fifty years, social scientists have accumulated data that allow us to measure wealth, inequality, and rates of violence in the past. The results are surprising–so much so that they can seem, as you suggest, counterintuitive. Foraging societies tended to be quite equal in wealth, if only because almost everyone was desperately poor (by one calculation, the average income was the equivalent of about $1.10 per day). They also tended to be very violent (by many calculations, more than 10 percent of foragers died violently). Farming societies tended to be less violent than foraging societies (5 percent rates of violent death were probably not uncommon) and not quite so poor (average incomes above $2.00 per day were common); but they were also massively unequal, regularly having tiny elites that owned thousands of times more than the ordinary peasant Fossil fuel societies, by contrast, are the safest and richest the world has ever seen, and are also more equal than all but the simplest foraging groups. Globally, the average person earns $25 per day and stands a 0.7 percent chance of dying violently, and in some countries progressive taxation has pushed income inequality down close to levels not seen since the simplest foraging societies (even if it is now again on the rise). In every era before AD 1800, life expectancy at birth averaged less than 25 years; now it is 63 years. Despite all the things we might not like about our own age, it would have seemed like a magical kingdom to people in the past.

What are some of the ways our values might change as we move away from a reliance on fossil fuels?

No one knows what the future will bring, but there are plenty of signs that we are rapidly moving beyond fossil fuels. I argue in this book that changes in the amount of energy humans harvest from the world pushes them into new kinds of organizations which in turn favor different interpretations of core human values; if this is right, we might expect the 21st century to see the biggest and profoundest transformation in values in history. The industrial revolution released a flood of energy in the 19th and 20th centuries, which favored societies that evolved toward democracy, rule of law, peace, freedom, and gender equality; the big question is whether the 21st century will see these trends going even further, or whether it will see them going into reverse. The answer, I suggest, is that it all depends. There are signs that in the short term–roughly the next generation–we will see increasing inequality and increasing acceptance that such inequality is right, along with increasing instability and violence. In the medium term–the next two or three generations–we may see the values of the fossil-fuel age go into overdrive; but in the longer term–say the next century or so–the transformations may become so massive that it no longer makes much sense to speak of human values at all, because what it means to be a human being might change more in the next 100 years than it has done in the previous 100,000.
