Alabama Beach Mouse (Peromyscus polionotus ammobates)

The photographer writes;
The Alabama beach mouse ekes out a living on a 14-mile stretch of the state's Fort Morgan Peninsula, where its dune habitat is fragmented by construction and lit up at night. Habitat saved under the Endangered Species Act (ESA) prevented these nocturnal mice from going the way of the dodo.

The photographer writes;
They survived the Ice Age, but condors barely held out against Homo sapiens. Many of these scavengers were shot or poisoned by fragments of lead left behind by hunters. In 1985 just nine wild birds remained. Captive breeding and reduced use of lead ammunition have brought the species back.

Ocelot, Leopardus pardalis.

The photographer writes;
Wild ocelots are gone from all U.S. states except Texas, driven out by human development. The elusive cats still roam the wilds of Central and South America, but there's little reliable data on their true numbers.

Gopher Tortoise (Gopherus polyphemus).

The photographer writes;
Gopher tortoises in the southeastern U.S. often end up as roadkill. Invasive fire ants and armadillos also prey on their eggs and young, while urban expansion, land conversion for pine plantations, and fire mismanagement degrade tortoise habitat, pushing these reptiles closer to the edge.

The Palos Verdes Blue butterfly is a small endangered butterfly native to the Palos Verdes Peninsula in southwest Los Angeles County, California. As its distribution has been proven to be limited to one single site it has one of the best claims to being the world's rarest…

The photographer writes;
Slipping into extinction almost unnoticed, the Dusky Seaside Sparrow, Ammodramus maritimus nigrescens -- found mainly on Florida's Merritt Island -- declined from roughly 3,000 pairs to none as its salt marsh habitat was sprayed with DDT and taken over for…

Linepithema flavescens, last seen in 1934
Linepithema flavescens, a small yellow ant from Haiti, is one of the species I re-described as part of my Ph.D. dissertation. All we know about this ant, apart from the brief notes on the specimen labels, is the external appearance of a few workers. Queens and males haven't been collected. No one has studied its ecology or behavior. The few existing museum specimens- gathered from two different field sites- may be too valuable to attempt DNA extraction.
A 1934 collection is the last time anyone has ever seen L. flavescens. As the natural…

"... species such as the house sparrow, snipe, starling, lapwing and corn bunting have been listed as birds of European concern, but these species have been declining in the United Kingdom's countryside for decades." Mark Avery, 2004.
A total of 9934 bird species were assessed for threatened species status by 2004; 1213 species were at risk of global extinction. In Indonesia 121 bird species were at risk of local extinction; in Brazil, 120 species. On average, over 18 bird species were at risk of local extinction per territory. […

grrlscientist | November 10, 2008tags: pets, cutest kitten in the world, streaming video
This video is a 5 minute amateur documentary about Hawai'i's endangered birds and the causes of their decline. The filmographer writes; "This was somewhat a difficult topic and we suffered from a lack of suitable footage of native birds as most endangered birds are not seen regularly as they used to be decades ago. Could have done better for sure, in fact if I had the chance I'd do it over for the sake of sharing the issues of the human impact on island birds." I think this is a great start for a conservation filmographer! [5:14]

For scientists, naturalists and birders, islands are the most amazing places on earth because their evolutionary legacy has provided them with their own fascinating flora and fauna that are found nowhere else in the world. But because humans also like to live on islands, along with their pets and crop plants, islands are a conservation nightmare, and certainly, the Hawai'ian islands are no exception. In Alvin Powell's book, The Race to Save…

I had the most fascinating telephone discussion with Bonnie Zimmermann, Vice President of the Indonesian Parrot Project, about the recent reported rediscovery of several individuals of the rarest cockatoo in the world.

You have to save the world (and I assume you also want to). You are the only one who can do so, and to do so, you have to destroy one or the other:

bleimanb | October 6, 2008Scientists in England working with an international conservation group have compiled a sample list which will be used much like the Dow Jones Industrial Average to track the overall status of endangered and threatened species in the world.

Every once in awhile, I read a paper that surprises me. Today, I read one of those papers, and it surprised me because it analyzes a phenomenon that is so obvious that I wonder why no one ever thought of studying it in a systematic and rigorous way before. I am referring to a paper that was just published by a team of…
