Robin Warne, Ph.D., a vertebrate physiological ecologist from the Department of Zoology at Southern Illinois University (SIU) at Carbondale, will present on the importance of gut microbiota for larval frogs. His seminar is scheduled for 4-5 p.m. Thursday, September 5, in 210 Moulton Hall as part of the School of Biological Sciences’ seminar series. Everyone is welcome and encouraged to attend.

Critical developmental windows can have profound effects on animal phenotypes, and exposure to varying factors during these periods influence the function and health of animals over lifetimes. Research in Warne’s lab at SIU explores the factors and determinants that shape critical developmental and disease windows in amphibians, including environmental stressors, neuroendocrine function, and gut microbiota.

This seminar will explore recent work demonstrating how hatching constitutes a critical window for establishment of a gut microbiome in larval frogs. Furthermore, variation in gut bacterial diversity during early larval stages determines long-term development, growth, and metabolic patterns, as well as influences susceptibility to pathogenic ranavirus infection—an emerging disease of ectothermic vertebrates. In amphibians, development rates and disease susceptibility are directly related, because allocation trade-offs between developmental physiology and immunity determine critical disease windows in larval amphibians. Specifically, late larval and metamorphic life stages constitute a critical disease window, when amphibians exhibit high vulnerability to ranavirus and other pathogens, however, rapid metamorphosis is an escape from ranavirus induced mortality.

Building upon these findings, we are developing and advancing approaches to modulate gut microbiomes and the metabolites they produce in order to affect target outcomes in wildlife and human physiology, health, and disease.

corso dog :: Article Creator Woman Hospitalized After Attack By 2 Dogs At Same Edmonton Home Where Boy Died: Lawyer UPDATE: On April 15, 2024, the City of Edmonton provided an update on the fatal attack. It said that prior to the deadly incident on April 1, "the city had no lawful basis to remove the dogs from the home." The city added that "all prior complaints about the dogs involved in this incident were investigated thoroughly and appropriate action was taken in accordance with the applicable legislation." The city also said a review found that its staff "acted appropriately in accordance with our standard practices and in compliance with the relevant legal constraints given the nature of past complaints and reports." A woman was hospitalized after being attacked in February by two large Cane Corso dogs at the same home where an 11-year-old boy was killed last week, the woman's lawyer told Global News. "I...

Colombian conservationist Ivan Lozano has hit on a brilliantly promising strategy to protect his country’s rare and endangered amphibians. His plan: Flood the market with them. Lozano is not hunting rare frogs in Colombia’s Andean forests. He is raising them himself and selling them at prices designed to undercut poachers and smugglers. If he can raise the frogs cheaply enough, and in large enough numbers, he might manage to drive down the market price to the point that poachers no longer find it worthwhile to harvest and smuggle the creatures onto the black markets. Lozano told The Associated Press that his company also encourages collectors to breed their own frogs. Picture yourself as a poacher. If the government toughens the legal penalties and steps up enforcement, you will shrug your shoulders; legal risks are a basic cost of doing business. Since the demand for your product already exists among foreign collectors and other buyers, tougher enforcement merely reduces supply a...

Burn scars, winter storms threaten rare and endangered species in San Gabriel Mountains - The Bakersfield Californian

LOS ANGELES — Up until a few weeks ago, the West Fork of the San Gabriel River was one of the most abundant wildlife habitats in Los Angeles County, a secluded and rugged area defined by its steep peaks, lush canyons and mixture of rare and endangered species. Recently however, a team of federal biologists and forest rangers was aghast when it visited the stream following the Bobcat fire, which has burned more than 115,000 acres in the heart of the San Gabriel Mountains National Monument. Terrain that once resembled a High Sierra granite gorge now looked like ground zero after a nuclear explosion, and the usually clean mountain air was sharp with the stench of smoke. Particularly unsettling were the bare and ashen slopes that were now primed to dissolve under pounding winter storms. A heavy mudslide, experts said, could reverse decades of conservation efforts by inundating the last outposts for such federally protected species as the Santa Ana sucker fish and Southern California m...
