SquaMates Ep. 9: The Herpetologist's Guide to the Galaxy

Herein, we applied the Sinervo et al. (2010) physiological model to predict the local extinction risk of three species of lizard from Patagonia. Sinervo wondered whether the French phenomenon of extinction would be seen in other parts of the world. Between 2006 and 2008, he and a team of scientists surveyed 48 species of the Sceloporus lizard at 200 sites in Mexico — populations for which they already had data going back to 1975, when the sites were first surveyed. 1996-03-21 · MANY species exhibit colour polymorphisms associated with alternative male reproductive strategies, including territorial males and 'sneaker males' that behave and look like females1–3. The Here, we compare recent and historical surveys for 48 Mexican lizard species at 200 sites. Since 1975, 12% of local populations have gone extinct.

Sinervo lizard

Females lay multiple clutches at monthly intervals ranging from April to August. Both males and females have home ranges and hatchling dispersal is limited (Doughty & Sinervo… 2010-05-13 2019-07-31 2021-03-24 In addition, Sinervo has assembled a global team of herpetologists to monitor lizard habitats on every continent. They will determine how much of an effect global warming is having on lizard populations, and they’ll try to predict when a population might go extinct. Barry Sinervo crosses the world every summer to go on a lizard quest. The herpetologist at the University of California, Santa Cruz, travels to the lowlands in countries such as Finland, France 1996-03-21 Sinervo wondered whether the French phenomenon of extinction would be seen in other parts of the world.

Sinervo began focusing his attention on lizard extinctions after he noticed an obvious trend during his field work in France. He identified an unsettling pattern of lizard extinctions with French researchers, Jean Clobert and Benoit Heulin, while they were surveying some of their well-documented populations. Sinervo’s frequent research collaborator Donald Miles, a fellow lizard expert and professor at Ohio University, remembers a “small but dedicated” group of ecologists and biologists sounding the alarm about climate change around the time he started working with Sinervo in 1993. Sinervo described the male lizard strategies as analogous to a game of rock, paper, scissors.

Spatial scale and temporal component of selection in side

Sinervo also led an international team of biologists in a survey of lizard populations worldwide that found an alarming pattern of population extinctions connected to climate change. Those findings, published in Science in 2010, led Sinervo to focus increasingly on the issue of climate change. Sinervo began focusing his attention on lizard extinctions after he noticed an obvious trend during his field work in France. He identified an unsettling pattern of lizard extinctions with French researchers, Jean Clobert and Benoit Heulin, while they were surveying some of their well-documented populations. Five percent of lizard species already have gone extinct, Sinervo said, and his team projects that if the planet continues to heat up at current rates, 20 percent of all lizard species could go Recently published in the prestigious academic journal PLOS One, Friedman and Sinervo report their findings from studying the 26 generations of the side-blotched lizard, a reptile common on the Pacific Coast of North America known for their distinct, polymorphic mating habit. The science of strategic at play Sinervo’s frequent research collaborator Donald Miles, a fellow lizard expert and professor at Ohio University, remembers a “small but dedicated” group of ecologists and biologists sounding the alarm about climate change around the time he started working with Sinervo in 1993. Larger lizard species, such as collared, leopard, and spiny lizards, and roadrunners are the main predators.

Male U. stansburiana exhibit three different mating strategies whose competitive dynamics are the first known example of a biological rock-paper-scissors game (Sinervo and Lively 1996). Sinervo, a lizard ecologist by training, hadn’t thought much about extinctions until he spent a summer surveying European common lizards in the south of France in 2003. That August, a deadly heat wave swept Europe, killing more than 30,000 people. As temperatures climbed well past 100°F in Paris, Sinervo knew how to adapt. When selection acts on social or behavioral traits, the fitness of an individual depends on the phenotypes of its competitors. Here, we describe methods and statistical inference for measuring natural selection in small social groups. We measured selection on throat color alleles that arises from mi … Commemorating the loss of "Dr.

“The technique should work for any sort of plant or animal (and maybe for human societies) where fitness has a strategic component, that is, where fitness of any behavior depends on frequency of other behaviors,” says Friedman about the What's more, Sinervo says, “Lizards that give live births, including those with really neat social behaviors, are five times more likely to go extinct from climate warming than egg-laying species." Standing in his lab, Sinervo holds up a tiny piece of PVC piping, spray-painted grey. Experimental manipulations of side-blotched lizards indicate that pleiotropy is an important component of correlational selection on side-blotched lizard morphs (Sinervo, 2000; Sinervo et al In that year, Barry Sinervo of the University of California, Santa Cruz and Curt Lively of Indiana University, Bloomington, published their new study of this lizard in California. Their main interest was to understand how and why males of this species exist in three different throat colours – orange, yellow and blue. It is predicted that climate change will cause species extinctions and distributional shifts in coming decades, but data to validate these predictions are relatively scarce. Here, we compare recent and historical surveys for 48 Mexican lizard species at 200 sites.
