Can chytridiomycosis be treated? In captive amphibians, chytridiomycosis can be successfully treated with antifungal medications and by disinfection of contaminated enclosures (Pessier and Mendelson, 2010). A variety of different antifungal medications have been described for the treatment of chytridiomycosis, however, one of the most common methods was developed at the Smithsonian National Zoo and uses a series of baths in the drug itraconazole (Nichols and Lamirande, 2000). Itraconazole baths have been used successfully in rescue operations that capture wild amphibians from populations that are experiencing deaths to chytridiomycosis (Gagliardo et al., 2008). Other potential treatment methods include the use of elevated body temperature and paradoxically, the antibiotic chloramphenicol. Treatment is not always 100% successful and not all amphibians tolerate treatment very well, therefore chytridiomycosis should always be treated with the advice of a veterinarian. Unfortunately, there are no good methods for the treatment of wild animals in the natural environment. It is very difficult or impossible to get enough of the antifungal medications into the environment to be able to successfully rid infected frogs of Bd. In the future it may be possible to treat some amphibians in the wild in order to reduce the intensity of infection to a less lethal level with the hope that animals could survive with a mild Bd infection (Briggs et al., 2010; Vrendenberg et al., 2010). Another promising area of research is looking at the possibility of introducing symbiotic bacteria that inhibit the growth of Bd into wild amphibian populations (Harris et al., 2009). So far, there is no evidence that a vaccine for chytridiomycosis could be effective for controlling the disease in wild populations (Stice and Briggs, 2010).

Why Frogs? Why Tuesday? - Houghton Mifflin Harcourt

David Wiesner’s Caldecott Medal Acceptance Speech for Tuesday

Why it should happen: Butch Jones has been building toward this. Out of the ashes of Lane Kiffin and Derek Dooley, Tennessee won five, then seven, then nine games in Jones’ first three seasons. And last year’s four losses were all of the painfully close variety – Oklahoma, Alabama, Florida and Arkansas beat the Vols by a combined 17 points. With 19 starters back, including multiple stars on both sides, it’s time to close the deal.

It’s a successful season if: The Wildcats win six games and reach their first bowl game since 2010. After consecutive 2-10 seasons, back-to-back 5-7 records would feel more like progress had Kentucky not collapsed from 5-1 and 4-1 starts the last two years. Breaking through to the postseason is now a must.

Why would you want to boil a frog? | Successful Workplace

At least as often as people ask me where I came up with the idea for the book, they want to know, "Why Tuesday?" When I decided to punctuate the story with the times of the day, it became clear that the mysterious element had to do with the particular day of the week when these strange things happened. So I tried to decide what the funniest day of the week was. I immediately discounted the weekend; Saturday and Sunday had too many connotations, as did Friday. Monday was next to go, being the first day of the work week, which left Tuesday, Wednesday, and Thursday. Wednesday’s spelling had always bothered me, so it was out. Thursday was all right, but the more I said "T-u-e-s-d-a-y," the more I like the "ooze" quality it had. It seemed to go with frogs.

Service biologists are working with our partners to monitor current spotted frog populations to assess population trends and distribution, and also improve and create habitat throughout the Great Basin to prevent the frog’s further decline. For example, our Reno Field Office in Nevada had a 10 year Conservation Agreement and Strategy for the Toiyabe Mountains and Northeast populations of Columbia spotted frogs, to coordinate monitoring and implement conservation measures to alleviate stressors to the species. Through implementation of the Conservation Agreement and Strategy, 36 ponds were created in central Nevada and all ponds have documented occupancy with 77 percent having breeding activity. And in Idaho, a Candidate Conservation Agreement with Assurances was completed to improve breeding, foraging, dispersal, hibernating habitat, and migration corridors for Columbia spotted frogs at Sam Noble Springs while allowing continued livestock use on these state lands. In addition, 41 ponds were constructed or enhanced on private lands in Idaho to increase breeding habitat and connectivity between existing populations. The recently completed a Comprehensive Conservation Plan which includes numerous activities aimed at improving aquatic health on the refuge, including 6 goals that will directly benefit Columbia spotted frogs. , and habitat improvement projects are occurring or are planned throughout the entire range of the , which are increasing our knowledge of life history characteristics, population fluctuations, effectiveness of habitat improvement projects, genetics, and stressors to the species. Research on Ozark hellbender reproductive health
The federally endangered is a large salamander that spends its life in clear, cool spring-fed streams, under large rocks or in crevices. Drastic declines have occurred in populations of the Ozark hellbender since the 1970s, and experts are still working to understand reasons for the salamander's decline. One of the tools we are working on with our partners to increase the population of hellbenders in a .
One factor potentially contributing to hellbender population decline is . Endocrine disrupting compounds, which have been shown to alter normal reproductive development in various aquatic species, have been detected in streams occupied by Ozark hellbenders. Although concentrations of these compounds were lower than EPA standards to protect aquatic life, biologists questioned whether the presence of these or other undetected compounds might be interfering with successful fertilization of eggs.
To address this question, our Columbia Missouri Ecological Services Field Office collaborated with the Missouri Department of Conservation to assess the sperm health of wild Ozark hellbenders. Since 2010, Service biologists have captured Ozark hellbenders during the breeding season and assessed the rates of motility (percentage of moving cells), viability (percentage of live cells), and concentration of sperm samples.
Preliminary results indicate that Ozark hellbenders are producing healthy sperm, with viability and motility rates approaching 100 percent in some instances. In addition, males used in the breeding program at the Saint Louis Zoo have been assessed and also appear to have healthy sperm. Although exact causes behind Ozark hellbender declines continue to remain unclear, these results certainly bode well for captive breeding efforts and for natural reproduction in the wild.

Crawfish frog research and restoration
in southeastern Indiana and its partners are working to understand the habitat requirements and breeding preference of crawfish frogs, a species that is rapidly declining throughout much of its range. While not federally listed as endangered or threatened, this species is susceptible to drastic population declines due habitat loss and habitat alterations. This frog requires a combination of grassland habitat, ephemeral breeding wetlands, and crayfish burrows, which limit the number and location of reestablishment sites.
