1821por Ringler, Eva, Pašukonis, Andrius, Fitch, W. Tecumseh, Huber, Ludwig, Hödl, Walter, Ringler, Max“…Contrary to the view of amphibian parental care as being stereotypical and fixed, these results demonstrate behavioral flexibility as an adaptive response to environmental and social uncertainty. …”

1828por Kaiser, Kristine, Devito, Julia, Jones, Caitlin G., Marentes, Adam, Perez, Rachel, Umeh, Lisa, Weickum, Regina M., McGovern, Kathryn E., Wilson, Emma H., Saltzman, Wendy“…Amphibian populations are declining globally. The potential contribution of glucocorticoid hormones to these declines has received little attention, but chronic elevation of glucocorticoids has been linked to a suite of negative outcomes across vertebrate taxa. …”

This approach involves in situ filtering of large volumes of water followed by amplification and sequencing of a short discriminative fragment from the 12S rDNA mitochondrial gene. …”

Despite similar evidence of population extinction in European fish populations and the associated risk of food aquaculture due to the emerging rosette agent Sphaerothecum destruens, an emerging infectious eukaryotic intracellular pathogen on the fungal–animal boundary, our understanding of current threats remained limited. …”
