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 C, 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...

RISK ASSESSMENT OF POTENTIAL INVASIVENESS OF EXOTIC REPTILES

RISK ASSESSMENT OF POTENTIAL INVASIVENESS OF EXOTIC REPTILES
IMPORTED TO SOUTH FLORIDA

Ikuko Fujisaki, Kristen M. Hart, Frank J. Mazzotti, Kenneth G. Rice, Skip Snow & Michael Rochford

2010. Biological Invasions 12: 2585-2596

Abstract: The recent explosion of exotic reptiles in south Florida requires effective management strategies. The objective of this study is to bring knowledge of ecological correlates and quantitative modeling methods into management by providing the foundation for a screening procedure that will identify potentially invasive species and assess adverse impacts associated with these species. We considered 17 variables and, based on model selection procedures, we identified the following significant predictors of establishment success: taxonomic order, maximum temperature match between a species' native range and Florida, animal sale price, and manageability (defined as a species' maintenance cost, aggressiveness, proneness to escape, and venomousness). Applying the models to predict establishment success of 33 reptiles that were most frequently imported through Miami and St. Petersburg ports from 2000 to 2005 and two additional reptiles of concern in Florida, we identified ei!
ght lizards and four snakes as potentially successful invaders. We further assessed adverse impacts associated with potential invaders, should they become established, by identifying species that are (1) dangerous to humans, (2) dangerous to the ecosystem (upper trophic-level predators), and (3) rapidly spreading. Controlling exotic reptiles can be expensive and labor intensive once they are established. Information on which species are potential invaders based on screening procedures and what impacts these species might cause will be a valuable contribution to the development of proactive management strategies.
