Effects of canopy cover on the landscape epidemiology of an amphibian chytrid fungus
… pathogen of amphibians that causes the disease chytridiomycosis and is one of the major contributors to recent population declines of amphibians. The prevalence of Bd should vary spatially across landscapes because survival of the pathogen is influenced by environmental variables. In particular, …

Prevalence assessment of the amphibian chytrid fungus Batrachochytrium dendrobatidis across two habitat types in East Tennessee
In light of the biodiversity crisis facing amphibian populations globally, studies investigating the pathogenic amphibian fungus Batrachochytrium dendrobatidis (Bd) are a foremost priority for biologists. Understanding effects of habitat variation on Bd prevalence is important for identifying …

Measuring and modeling the effects of temperature on the amphibian chytrid fungus and assessing amphibian skin bacterial communities
… efforts. One example of this is the amphibian chytrid fungus, Batrachochytrium dendrobatidis (Bd), which causes the disease chytridiomycosis and has been linked to amphibian populations declines worldwide. There have been numerous attempts to mitigate the effects of Bd on amphibians, all with …

Impact of Chytrid fungus pathogen on the skin microbiome of frogs in northern Idaho and Turnbull National Wildlife Refuge, Washington
… are under threat from the infectious disease chytridiomycosis, which is caused by the chytrid fungus Batrachochytrium dendrobatidis (Bd). Bd is associated with the population declines of an estimated 501 species, 90 of which are presumed or confirmed extinct, making this the greatest …

Movements of adult western toads, Bufo boreas, in a managed forest landscape and the incidence of a disease in southwestern British Columbia
… is any evidence of the infectious disease, the chytrid fungus (Batrachochytrium dendrobatidis), in this species in British Columbia. I used radio-telemetry to follow daily movement patterns of 23 adult male toads in a fragmented landscape near Vancouver, BC, composed of forest patches and small, …

Eukaryotic Parasites of Toxic and Bloom-forming Diatoms: Molecular insights in their diversity and physiology
… identification of a transatlantic distributed chytrid infecting the spring bloom-dominating diatom Skeletonema, advocating for a high ecological relevance for this parasite. Finally we characterised a stable cultivated pathosystem involving the freshwater diatom Asterionella formosa and a …

Natural History and Conservation of Bolitoglossine Salamanders in Central Panama
… ground-level habitats within the study site. A chytrid fungus, Batrachochytrium dendrobatidis, was detected on B. biseriata and O. parvipes but I did not observe any mortality resulting from infection. Oedipina at the site were detected mainly on wet nights. Oedipina complex and B. biseriata …

Composition, Distribution, and Conservation of the Herpetofauna of Santa Barbara Mountain, Honduras
… found, and determining if the amphibian disease chytridiomycosis is present and in which locations. A community education objective, which included training local people as field assistants, was also pursued as a means to promote conservation of amphibians and reptiles and Santa Barbara National …

Evaluating efficacy of anti-Batrachochytrium dendrobatidis probiotic treatment on Pacific Chorus Frogs (Pseudacris regilla) at current and modeled climate change temperatures
… due to a variety of threats, including the chytrid fungal pathogen, Batrachochytrium dendrobatidis (Bd), the causative agent of the disease chytridiomycosis. Climate change and other stressors can have complicated interactions with amphibian disease. Some amphibian populations are less …

State-wide assessment of status, predicted distribution, and landscape-level habitat suitability of amphibians and reptiles in Montana
… assessment of the distribution of the pathogenic chytrid fungus (<i>Batrachochytrium dendrobatidis</i>) (Bd) was undertaken using PCR-based detection in skin swabs or tissue samples. Bd was found across Montana in 6 of the 9 species tested at a variety of elevations, habitats, and distances from …

Opportunities and Constraints of Sierra Nevada Meadow Restoration for the Mountain Yellow-Legged Frog Species Complex
… may also promote MYLF persistence with the chytrid fungus via warm expansive aquatic habitat that reduces zoospore density and production, disincentivizes transmission through aggregations and overwintering, and promotes overall MYLF fitness. These results indicate that increased species …

Life history implications of the mother's choice for a larval habitat. Niche choice and niche conformance in the fire salamander, Salamandra salamandra
… and emerging infectious diseases such as chytridiomycosis caused by the chytrid fungus *Batrachochytrium salamandrivorans* (*Bsal*). In the European fire salamander (*Salamandra salamandra*), this fungus has led to numerous population collapses and thus, conservation efforts have increased …

The Animal-fungi Hybrid Cell Cycle of the Zoosporic Fungus Spizellomyces punctatus - a New Model to Understand Evolution of Eukaryotic Cell Cycle Control
<p>The cell cycle is arguably one of the most conserved regulatory networks within Eukaryotes. Despite the animals and fungi are sibling “kingdoms” within the Opisthokont supergroup, the core transcription factors that control commitment to cell division (E2F and SBF, respectively) and their …
