Diamondback terrapin resource use in a seagrass-dominated coastal bay varies by life stage Diamondback terrapin resource use in a seagrass-dominated coastal bay varies by life stage
Diamondback terrapins, hereafter referred to as terrapins, are the only estuarine turtle species native to North America. However, terrapins are also occasionally found in marine habitats, such as seagrass beds, and yet little is known about how they use those marine habitats. We sampled epidermis from terrapins (Malaclemys terrapin macrospilota) inhabiting a seagrass-dominated coastal...
Human perturbations to mercury in global rivers Human perturbations to mercury in global rivers
Mercury compounds are potent neurotoxins that pose threats to human health, primarily through fish consumption. Rivers, critical for drinking water and food supply, have seen rapid increases in mercury concentrations and export to coastal margins since the Industrial Revolution (~1850). However, patterns of these changes remain understudied, limiting assessments of environmental policies...
Elevated CO2 enables brackish marsh transgression into freshwater forested wetlands while stimulating CH4 emissions Elevated CO2 enables brackish marsh transgression into freshwater forested wetlands while stimulating CH4 emissions
Wetlands are significant carbon (C) sinks and are expected to promote greater C assimilation as atmospheric CO2 concentrations rise. However, the fate of C with environmental change along fresh-to-oligohaline wetland transitions is not well understood. We established an ex-situ mesocosm experiment to mimic future elevated atmospheric CO2 concentrations (eCO2, 720 ppm) versus current (380...
