Evolutionary Adaptation Of Marine Zooplankton To Global Change, Hans Dam
Evolutionary Adaptation Of Marine Zooplankton To Global Change, Hans Dam
Hans G. Dam
Predicting the response of the biota to global change remains a formidable endeavor. Zooplankton face challenges related to global warming, ocean acidification, the proliferation of toxic algal blooms, and increasing pollution, eutrophication, and hypoxia. They can respond to these changes by phenotypic plasticity or genetic adaptation. Using the concept of the evolution of reaction norms, I address how adaptive responses can be unequivocally discerned from phenotypic plasticity. To date, relatively few zooplankton studies have been designed for such a purpose. As case studies, I review the evidence for zooplankton adaptation to toxic algal blooms, hypoxia, and climate change. Predicting the …
Basking Behavior Of Emydid Turtles (Chysemys Picta Marginata, Graptemys Geographica, And Trachemys Scripta Elegans) In An Urban Landscape, W. Peterman, Travis Ryan
Basking Behavior Of Emydid Turtles (Chysemys Picta Marginata, Graptemys Geographica, And Trachemys Scripta Elegans) In An Urban Landscape, W. Peterman, Travis Ryan
Travis J. Ryan
Basking is common in emydid turtles and is generally accepted to be in thermoregulatory behavior. In 2004, we quantified and described the basking behavior of turtles in the Central Canal of Indianapolis. This canal system runs through an urban landscape that is dominated by fragmented woodlots, residential areas. and commercial areas. We observed that basking turtles exhibited variable basking behavior. with spatial and temporal shins in basking behavior from east-facing banks in the morning to west-facing banks in the afternoon. Turtles in the Central Canal are subject to frequent disturbance, which altered basking behavior. Many turtles forewent aerial basking on …
