WELCOME TO THE CFZ BLOG NETWORK: COME AND JOIN THE FUN

Half a century ago, Belgian Zoologist Bernard Heuvelmans first codified cryptozoology in his book On the Track of Unknown Animals.

The Centre for Fortean Zoology (CFZ) are still on the track, and have been since 1992. But as if chasing unknown animals wasn't enough, we are involved in education, conservation, and good old-fashioned natural history! We already have three journals, the largest cryptozoological publishing house in the world, CFZtv, and the largest cryptozoological conference in the English-speaking world, but in January 2009 someone suggested that we started a daily online magazine! The CFZ bloggo is a collaborative effort by a coalition of members, friends, and supporters of the CFZ, and covers all the subjects with which we deal, with a smattering of music, high strangeness and surreal humour to make up the mix.

It is edited by CFZ Director Jon Downes, and subbed by the lovely Lizzy Bitakara'mire (formerly Clancy), scourge of improper syntax. The daily newsblog is edited by Corinna Downes, head administratrix of the CFZ, and the indexing is done by Lee Canty and Kathy Imbriani. There is regular news from the CFZ Mystery Cat study group, and regular fortean bird news from 'The Watcher of the Skies'. Regular bloggers include Dr Karl Shuker, Dale Drinnon, Richard Muirhead and Richard Freeman.The CFZ bloggo is updated daily, and there's nothing quite like it anywhere else. Come and join us...

CAN INVASIVE BURMESE PYTHONS INHABIT TEMPERATE REGIONS OF THE SOUTHEASTERN UNITED STATES?

CAN INVASIVE BURMESE PYTHONS INHABIT TEMPERATE REGIONS OF THE SOUTHEASTERN UNITED STATES?

Michael E. Dorcas, John D. Willson & J. Whitfield Gibbons

2011. Biological Invasions 13: 793-802

Abstract: Understanding potential for range expansion is critical when evaluating the risk posed by invasive species. Burmese Pythons (Python molurus bivittatus) are established in southern Florida and pose a significant threat to native ecosystems. Recent studies indicate that climate suitable for the species P. molurus exists throughout much of the southern United States. We examined survivorship, thermal biology, and behavior of Burmese Pythons from South Florida in a semi-natural enclosure in South Carolina, where winters are appreciably cooler than in Florida, but within the predicted region of suitable climate. All pythons acclimated to the enclosure, but most died after failing to seek appropriate refugia during sub-freezing weather. The remaining snakes used refugia but died during an unusually cold period in January 2010. Although all snakes died during the study, most survived extended periods at temperatures below those typical of southern Florida and none exhibited obvious signs of disease. Our study represents a first step in evaluating the results of climate matching models and we address factors that may affect range expansion in this invasive species.
