PFAS from a Discrete‐Event Terrestrial Source Migrates with Groundwater to Intertidal Seepages

Groundwater, EarlyView.
PFAS is conveyed to the coastal intertidal zone from sources across the terrestrial landscape. Discharge of PFAS into the coastal ecosystem is complicated in space and time by the ongoing bi‐directional exchange of terrestrial groundwater and ocean water driven by tidal pumping within discharge areas.

A new South American darter (Crenuchidae: Characidium) from rivers draining the Northeastern Mata Atlantica Freshwater Ecoregion, Brazil: morphological and molecular evidence

Journal of Fish Biology, EarlyView.
Abstract Characidium tupi, a new species from rivers draining the southern portion of the Northeastern Mata Atlantica Freshwater Ecoregion, is described. The new species can be distinguished from all congeners by its colour pattern, including 7–14 dark bars enlarged and more conspicuous on their ventralmost portion, resulting in a longitudinal series ...
