Juvenile ribbontail stingrays, Taeniura lymma (Forsskål, 1775) of the tropical West Pacific inhabit mangal and seagrass nurseries that often experience rapid and extreme increases in water temperature. We hypothesized that juvenile rays possess a thermal strategy similar to other hyperthermic specialists, in which fish prefer high temperatures, are always(More)
Thermal acclimation responses in sheepshead minnow Cyprinodon variegatus were quantified by transfer and reciprocal transfer of fish between 11.1° and 18.2°C, between 18.2° and 25.7°C, or between 25.7° and 32.8°C. Changes in thermal acclimation status were assessed by posttransfer time series determinations of thermal tolerance (i.e., critical thermal(More)
Atlantic stingrays, Dasyatis sabina, are common residents of shallow-water seagrass habitats that experience natural cycles of severe hypoxia during summer months. We hypothesized that stingrays exposed to hypoxic episodes would improve their hypoxia tolerance by increasing branchial surface area and altering blood oxygen-carrying capacity. To this end, we(More)
The Sacramento splittail (Pogonichthys macrolepidotus) is a minnow endemic to the highly modified San Francisco Estuary of California, USA and its associated rivers and tributaries. This species is composed of two genetically distinct populations, which, according to field observations and otolith strontium signatures, show largely allopatric distribution(More)
