One paper (Jani et al. 2021) describes how infection of mountain yellow-legged frogs by the amphibian chytrid fungus causes long-term changes to the community of bacteria inhabiting the frogs’ skin (“microbiome”). Given the myriad roles played by the microbiome, including those related to immunity, changes to its structure could have additional impacts on frogs. The second paper (Joseph and Knapp 2021) shows how using the results of visual encounter surveys in analysis of mark-recapture data can improve estimates of population size. Links to the full text of both papers is available on the Publications page.
Exciting news: we just pushed the Sierra Lakes Inventory Project data set to the Environmental Data Initiative data portal! Roland Knapp ran the SLIP project from 1995-2002 and collected data on >8,000 Sierra Nevada water bodies. We owe Claire Pavelka our gratitude for making this data publication a reality. Claire was a fellow with the Environmental Data Initiative summer data science fellowship program in 2020.
