Invasive carps are ecologically and economically problematic fish species in many large river basins in the United States and pose a threat to aquatic ecosystems throughout much of North America. Four species of invasive carps: black carp (Mylopharyngodon piceus), grass carp (Ctenopharyngodon idella), silver carp (Hypophthalmichthys molitrix) and bighead carp...
Effects of diet and provisioning behavior on chick growth in Adélie Penguins (Pygoscelis adeliae)
Scott Jennings, Katie M. Dugger, Grant Ballard, David G. Ainley
2021, Waterbirds (44) 55-67
When provisioning chicks, parents trade-off their time, energy, and other resources to maximize reproductive success. As parents adjust investment to maximize their fitness, impacts on offspring growth can occur. We investigated provisioning and chick growth of Adélie Penguins (Pygoscelis adeliae) at one of the...

Laetitia Plaisance, Kenan O. Matterson, Katharina Fabricius, Sergei V. Drovetski, Christoph F. J. Meyer, Nancy Knowlton
2021, PLoS ONE (16)
Small cryptic invertebrates (the cryptofauna) are extremely abundant, ecologically important, and species rich on coral reefs. Ongoing ocean acidification is likely to have both direct effects on the biology of these organisms, as well as indirect effects through cascading impacts on their habitats and trophic relationships. Naturally acidified habitats have...

Life-history attributes of Arctic-breeding birds drive uneven responses to environmental variability across different phases of the reproductive cycle
Daniel R. Ruthrauff, Vijay P. Patil, Jerry W. Hupp, David H. Ward
2021, Ecology and Evolution (11) 18514-18530
Animals exhibit varied life-history traits that reflect adaptive responses to their environments. For Arctic-breeding birds, traits related to diet, egg nutrient allocation, clutch size, and chick growth are predicted to be under increasing selection pressure due to rapid climate change and increasing environmental variability across high-latitude...
