Putting a number on it: Maned wolf survival rates
by DeLene Beeland in Wild Muse
How can you conserve a large carnivore when you don’t know how many of them exist? It’s a difficult task, and so a few scientists at the Jaguar Conservation Fund opted to put a number on their target population… only it’s not jaguars they were trying to pinpoint, it was the lesser known maned wolf. [...]... Read more »

Bedeviled Tasmanian devils
by DeLene Beeland in Wild Muse
Wild Muse just perused the latest issue of Conservation Biology and went foraging for substantive research to post about… Hold on tight because we are going to Tasmania. To the Forestier peninsula in southeastern Tasmania, to be exact – where Tasmanian devils are pinned down by a catastrophic disease. Unfortunately, it will not be all fun [...]... Read more »

Stayin' Alive
by Iddo Friedberg in Byte Size Biology
A small primate which was classified as endangered by the IUCN sixty years ago, and is endemic to Sri Lanka. It was seen only four times since 1937, and was thought to be extinct as it was not observed between 1939 and 2002. Living in the forest, the main cause for its endangerment is habitat destruction — logging, etc. Today, the Zoological Society of London published the first pictures in a long time of this little eusive fella. They also captured it briefly, and measured it before rel........ Read more »

Only thirty years ago, tens of millions of White-rumped Vultures, Gyps bengalensis,
were flying the skies of Asia. They are now classified as Critically Endangered.

My sea turtle hazard is worse than your sea turtle hazard
by Scott A. in Thriving Oceans
My sea turtle hazard is worse than your sea turtle hazard. Of course. Sounds logical. And more importantly it falls within that quirky social dynamic called HUMAN NATURE. But the results of bias within the scientific community is an interesting topic; especially when you add the sea turtle variable and the number of threats [...]... Read more »

Will Climate Change Alter Sea Turtle Populations to the Point of Extinction?
by Scott A. in Thriving Oceans
Our planet is an intriguing concoction of variables that meld together for successes spanning the organization of life (species, populations, communities, and ecosystems). It is literally an evolutionary process that is ecologically driven. And as a genotypic sex determined species, we seem to have an inherent fascination with the mysterious adaptive significance of environmental sex [...]... Read more »

Copepod Power
by Kelsey in Mauka to Makai
It’s human nature to think of the big bad animals that eat other animals as powerful and the animals that get eaten as wimpy. Of course, humans are often wrong (see “clusterf**kery”). Copepods get eaten by lots of animals—even by critters like jellyfish and right whales, which are known for their lack of speed—but they’re [...]... Read more »

Rump-Shaking Red-Eyed Treefrogs
by Kelsey in Mauka to Makai
Ensuring paternity is not easy for male red-eyed treefrogs. At night, males perch themselves on the branches of saplings and make a sound called a “chack.” Each male hopes that a female will find his chack to be the sexiest chack of all—if she can even distinguish his chack from those of the other males. [...]... Read more »

Bycatch Claims Sea Turtles By the Millions

It’s an article packed full of potential contention as it speaks to a variety of issues involving fisheries management. So thank God we are dealing with a charismatic marine species or we just may be contemplating their extinction. But then again, perhaps we are doing just that since all 7 species of marine turtles are [...]... Read more »

Killing Sharks: Is Ocean Science Compatible with Ocean Conservation?

I’ll be perfectly honest…I’ve been sitting on this essay from Conservation Biology for the last week or so as I mulled over my approach on breaching this topic.

Ass-Dragging Caterpillars Evolved from Bullies

Suppose you’re a caterpillar. You’ve just built yourself a nice home by sewing leaves together with silk and then some jackass invades your turf. How do you defend your home?

History of land use determines threat and rarity in mangrove tree species
by Jeremy in Voltage Gate
A new study from PLoS ONE was published last week assessing the threat to mangrove tree species around the world based on IUCN Red List data. At first glance the paper might seem to be just another bleak walk through the anthropogenic dismantling of a fragile biome, but there are some excellent issues presented regarding our relationship between the land and its inhabitants and the interconnectedness of rarity and threat level....

Polar Bear: Evolved

A recent study reports that grizzly bears are encroaching on polar bear habitat in northern Manitoba. That could be a bad thing—or it could just be a thing.

Demonstrating synergy between functional groups: Burrowing mammals and megaherbivores
by Jeremy in Voltage Gate
Davidson et al. published another study a few weeks ago in Ecology further exploring the relationships between black-tailed prairie dogs and their much maligned neighbors, Bos taurus, cattle. Prairie dogs have been generally regarded as a danger to cattle by ranchers and removed through poisoning or other means. Overgrazing can lead to desertification, further threatening these animals. But that's a relatively new trend in a long and complex history of interaction between prairie dogs and m........ Read more »

Shouldering: Penis Extraction in Rove Beetles
by Kelsey in Mauka to Makai
I don’t “have a thing” for critters with remarkable genitalia. (I swear.) But, while researching barnacle sex, I came across a paper about a male beetle with an intromittant organ (penis) so long and flexible that he has to sling it over his shoulder to keep it safe. Clearly, I couldn’t keep such information to [...]... Read more »

Finding a home for jaguars
A jaguar (Panthera onca). From Flickr user Prosper 973.
One year ago this week Macho B was euthanized. He had been captured in mid-February of 2009, the only known jaguar living inside the United States, but after he was caught and fitted with a radio collar his health quickly deteriorated. When he nearly stopped moving he was recaptured, taken to the Phoenix zoo, and put to sleep when it was discovered that he was suffering from irreparable kidney failure.
At first it seemed as if his ca........ Read more »
