Sex‐Specific Atlantic Salmon Upstream Passage and Fallback at a Natural Cascade After Dam Removal

Fisheries Management and Ecology, EarlyView.
ABSTRACT In the Boquet River (NY, USA) a low‐head dam set above a ~200‐m bedrock cascade was removed in 2015. We used radio‐telemetry to assess landlocked Atlantic salmon passage at the remaining cascade (2020, 2022). Across years, 52% of males (13/25) attempted cascade passage whereas females made no discernable attempts (0/11).

The Zooplankton International Geospatial dataset: A global repository of spatiotemporal freshwater zooplankton community composition data from lakes and reservoirs to support ecological research

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Zooplankton transfer substantial energy in aquatic food webs and are used as indicators of environmental change. Syntheses of zooplankton community dynamics globally require datasets that span a wide range of environmental gradients; however, these datasets are limited due to methodological differences across programs, taxonomic ...

Interplay of Ser273 Phosphorylation and K268 and K293 Acetylation in PPARγ: Implications for PPARγ Activation

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 9, Page 1597-1609, September 2026.
ABSTRACT Post‐translational modifications (PTMs) play a critical role in regulating the transcriptional activity of PPARγ, a nuclear receptor central to glucose and lipid homeostasis. Among these, lysine acetylation at K268 and K293 and phosphorylation at S273 are particularly relevant to insulin sensitivity.
