The distribution and mitochondrial genotype of the hydroid is correlated with its pelagic substrate type in the tropical and subtropical western Atlantic Ocean.

The pelagic brown macroalga supports rich biological communities in the tropical and subtropical Atlantic region, including a variety of epiphytic invertebrates that grow on the itself. The thecate hydroid is commonly found growing on some, but not all, forms. In this study, we examined the relationship between and its pelagic substrate across a broad geographic area over the course of 4 years (2015-2018).

Fitter frogs from polluted ponds: The complex impacts of human-altered environments.

Human-modified habitats rarely yield outcomes that are aligned with conservation ideals. Landscapes that are subdivided by roads are no exception, precipitating negative impacts on populations due to fragmentation, pollution, and road kill. Although many populations in human-modified habitats show evidence for local adaptation, rarely does environmental change yield outright benefits for populations of conservation interest.
