FORT scientists, Dr. Sara Oyler-McCance, Jennifer Fike, Dr. Bob Reed and others recently published an article entitled,"Environmental DNA (eDNA) Sampling Improves Occurrence and Detection Estimates of Invasive Burmese Pythons" in the journal PloS ONE. Giant constrictor snakes pose a threat to native species and the ecological restoration of the Florida Everglades.
Research Wildlife Biologist, Dr. Bob Reed, was recently interviewed by Retro Report, which publishes essays and documentary videos that re-examine leading stories. His comments and emphasis on the continuing lack of effective prevention contributed to the April 5, 2015 New York Times story on the unwanted snake species, the Burmese python (Python bivittatus), that is disrupting the ecosystem balance in the Florida Everglades.
A new study provides the first empirical evidence that Burmese pythons (Python bivittatus) caused reductions in marsh rabbit populations in Everglades National Park, after researchers had discovered Burmese pythons ate 77 percent of radio-tracked marsh rabbits. A new publication by the University of Florida and the U.S.
Dr. Bob Reed was interviewed by CBS News for a featured story, "Burmese pythons are taking over the Everglades," which was published on March 19, 2015 shortly after the release of a cooperative study with U.S.
Invasive species have become one of the greatest environmental challenges of the 21st century in economic, environmental, and human health costs. In fact, invasive species cost an estimated $120 billion per year in the United States. The Invasive Species Science Branch at the Fort Collins Science Center provides research and technical assistance relating to management concerns for invasive species, including understanding how these species are introduced, identifying areas vulnerable to invas
Michelle McEachern (FORT) spoke with Yael Herman at OurNationalParks.US on December 4, 2014 regarding an article about Argentine tegus in southern Florida. They discussed why scientists and land managers are concerned about Argentine tegus, how tegus arrived in southern Florida, if tegus pose the same threat as the Burmese python, how to control Argentine tegus, and whether Argentine tegus pose a threat to humans. A publication date for this article is unknown.
The Weather Channel's Secrets of the Earth "Animal Invaders": FORT Invasive Species Scientists Highlighted
"Secrets of the Earth: Animal Invaders" debuted Monday, December 1, at 7:00 p.m. MST on The Weather Channel. The show covered invasive animals in America from Burmese pythons in the Everglades to snake-like fish in the Potomac and killer bees in Texas. A lack of predators is helping these invasive species to take control in certain areas.
FORT's Bob Reed was recently interviewed by Amy Grisdale for an article on Burmese Pythons in the Everglades. The article was published in issue 14 of World of Animals Magazine. The Burmese python, one of the largest snakes in the world, is native to south-east Asia, but in recent years many have made themselves at home in the Everglades after escaping from captivity or even having been released by unknowing pet owners.
Burmese Pythons are one of the largest snakes in the world and a mainstay of the pet trade resulting in the establishment of an invasive population in South Florida. Researching the invasive population has lead scientists to learn more about the biology of this species. A recent capture of a relatively small sized pregnant female in Florida suggests that P. molurus may mature more rapidly than otherwise thought, in the wild. Typical growth rates in Florida or Asia are undoubtedly slower.
A new publication has been released by FORT scientists about invasive Burmese pythons. Burmese pythons (Python molurus bivittatus) are now established across a large area of southern Florida, USA, including all of Everglades National Park. The presence of these large-bodied snakes in the continental United States has attracted intense media attention, including regular reference to the possibility of these snakes preying on humans.

A new USGS podcast features FORT scientist and co-author Robert Reed discussing the results of a recent scientific paper published in the Proceedings of the National Academy of Sciences describing the apparent effects of Burmese python predation on mid-sized mammals in Everglades National Park.
A new Web feature describes FORT zoologist Gordon Rodda's illustrious 25-year career researching the ecology and impacts of invasive snake species and developing means of control and containment. Dr. Rodda has been intimately involved in what have proven to be two of the biggest reptile-invasion problems in the U.S. and its territories: the brown treesnake on Guam, and giant constrictor snakes in south Florida.
Burmese pythons appear to be having a marked effect on some prey populations in South Florida, according to a paper published online 30 January 2012 in the Proceedings of the National Academy of Sciences. The research conducted by USGS, NPS, and university scientists shows a strong correlation between abundance of pythons in an area and precipitous declines in certain mid-sized mammal populations, such as marsh rabbits and raccoons.
A new paper by USGS scientists Gordon Rodda, Catherine Jarnevich, and Robert Reed describes the challenges in using certain models to produce climate-matching maps that forecast where invasive animals could potentially become established, with an emphasis on Burmese pythons. Currently, Burmese pythons are established in southern Florida. The new paper, published Feb.
Right now in Florida, non-native, giant constrictor snakes—pythons, anacondas, and the boa constrictor—are being found in the wild, and two species have established several breeding populations. The snakes pose a considerable resource management challenge for agencies charged with preserving native ecosystems and species.
In recent years, media and other reports of non-native, giant constrictor snakes found in both wild and urbanized areas of southern Florida is alarming. Several snake species are known to be breeding and appear to be spreading northward. The Fort Collins Science Center, National Park Service, U.S. Fish and Wildlife Service, and other cooperators are collaborating on research and testing intervention methods to understand and control these novel predators.
The U.S. Department of the Interior recently recognized FORT Research Zoologist Thomas J.

Drs.
Invasive Burmese pythons could find comfortable climatic conditions in roughly one third of the United States according to new "climate maps" developed by FORT scientists. Although other factors such as type of food available and suitable shelter also play a role, Burmese pythons and other giant constrictor snakes have shown themselves to be highly adaptable to new environments.
Invasive species of plants, animals, diseases, and pathogens are estimated to cause more than $137 billion annually in damage to Americans in economic, ecological, and human health costs. Invasive species are best managed by preventing their establishment in the first place or by halting their spread to unaffected areas. But how? The USGS, NASA, and Colorado State University have teamed up to develop a tool to map invasive species and predict where they could be headed.
The cryptic and nocturnal habits of bats render it difficult to assess trends in the status of their populations. To meet this challenge, USGS biologists Mike Bogan and Tom O'Shea hosted an expert workshop to examine the topic of monitoring the status of bat populations. The proceedings are contained in a newly released report, “Monitoring Trends in Bat Populations of the United States and Territories: Problems and Prospects,” Information and Technology Report USGS/BRD/ITR—2003-003.
Over 22 million of the current 34 million acres of the USDA’s Conservation Reserve Program (CRP) contracts will expire in 2007 and 2008. With that rapidly approaching reality in mind, the USDA Farm Service Agency and the U.S. Geological Survey's Fort Collins Science Center sponsored a national conference June 6-8 in Fort Collins, Colorado, on the future of the Conservation Reserve Program.
The National Wildlife Refuge System Improvement Act of 1997 requires that all U.S. Fish and Wildlife Service National Wildlife Refuges develop Comprehensive Conservation Plans (CCPs) to guide refuge management over the next 15 years. One of the FWS’s specific needs was improving the science component of these plans.
The Conservation Reserve Program remains the largest environmental program administered by the U.S. Department of Agriculture, with enrollment exceeding 34 million acres nationwide. Because improvement in program performance is an important goal of CRP administrators, participants' input on how the program is working "on the ground" is an important factor in its evaluation.
These days, natural resource management is as much about effective human relations as it is about sound science. But many land, water, and resource managers struggle with the social components of their work. To address this need, the U.S. Fish and Wildlife Service's (FWS) National Conservation Training Center (NCTC) sponsored a course in Basic Natural Resource Negotiation May 7-9 in Fort Pierce, Florida.
During November 11-16, USGS scientists Jim Sartoris, Joan Thullen, and Larry Barber will present a paper entitled "Effect of hemi-marsh reconfiguration on nitrogen transformations in a southern California treatment wetland" at the Seventh International Conference on Wetland Systems for Water Pollution Control in Lake Buena Vista, Florida.
