Differences in early developmental rate and yolk conversion efficiency in offspring of trout with alternative life histories [PDF]

, 2016
Partial migration, in which some individuals of a population migrate while other individuals remain resident, is generally associated with ontogenetic shifts to better feeding areas or as a response to environmental instability, but its underlying ...

Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

River Research and Applications, EarlyView.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

Multistressor Interaction of Perfluorooctane Sulfonate (PFOS) and Temperature in Two Estuarine Fish Species, Red Drum (Sciaenops ocellatus) and Sheepshead Minnow (Cyprinodon variegatus)

Environmental Toxicology, EarlyView.
ABSTRACT Perfluorooctane sulfonate (PFOS), a perfluoroalkyl substance (PFAS), is characterized by a long, fluorinated carbon chain which makes it ideal for oil‐ and water‐repellent products but detrimental for the environment, where it persists and accumulates in organisms.

Environmental Contaminant Accumulation in Freshwater Turtles Inhabiting Three Rivers of the Permian Basin, New Mexico, USA

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater turtles are valuable sentinels of aquatic systems due to their long lifespans and resilience in environments impacted by contaminants. The Permian Basin, dominated by the oil and gas sector, spans western Texas and southeastern New Mexico, USA, including the Pecos River and its tributaries, the Delaware and Black Rivers.
