Wildlife corridors sometimes help invasive species spread, UF research finds
In a classic example of the law of unintended consequences, new University of Florida research suggests that wildlife corridors – strips of natural land created to reconnect habitats separated by agriculture or human activities -- can sometimes encourage the spread of invasive species such as one type of fire ant. The findings are particularly important in Florida, where invasive species are a vexing problem. The Sunshine State plays host to animals such as Cuban tree frogs, green iguanas and feral hogs. In 2013, the Florida Fish and Wildlife Conservation Commission even sponsored a Burmese python hunting challenge. The discovery also comes as a team of explorers prepares to embark this fall on its second 1,000-mile expedition to raise support for the Florida Wildlife Corridor. The organization’s goal is to create a corridor stretching from Everglades National Park to the Okefenokee National Wildlife Refuge in Georgia. http://www.esajournals.org/doi/abs/10.1890/14-0169.1 [more...]

Celebrate the continued excellence of Michelle Mack and her recent paper in Nature
Thermokarst lakes formed across vast regions of Siberia and Alaska during the last deglaciation and are thought to be a net source of atmospheric methane and carbon dioxide during the Holocene epoch1. However, the same thermokarst lakes can also sequester carbon5, and it remains uncertain whether carbon uptake by thermokarst lakes can offset their greenhouse gas emissions. Here we use field observations of Siberian permafrost exposures, radiocarbon dating and spatial analyses to quantify Holocene carbon stocks and fluxes in lake sediments overlying thawed Pleistocene-aged permafrost. We find that carbon accumulation in deep thermokarst-lake sediments since the last deglaciation is about 1.6 times larger than the mass of Pleistocene-aged permafrost carbon released as greenhouse gases when the lakes first formed. .
