Handgrip and Acute Hemodynamic Responses During Cyclic Exercise: Randomized Clinical Trial. [PDF]

J Clin Hypertens (Greenwich)
ABSTRACT During exercise, fine hemodynamic adjustments are essential to ensure adequate energy supply. Although cyclic treadmill exercise has been widely studied, isometric exercise with Handgrip (HG) has gained relevance in conditioning and rehabilitation contexts, yet data on the acute hemodynamic effects of combining these modalities remain scarce ...

Community-driven variations in snow algae color modulate snow albedo reduction. [PDF]

New Phytol
Summary Snow algae blooms visibly alter snow color and surface energy balance, yet the biological basis of this variability remains unclear. We investigated how pigment composition and community structure shape the optical properties of snow algae blooms of distinct colors – red, orange, and green – co‐occurring within the same snowfield in Glacier ...

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).

Environmental Justice in the Brazilian Coastal Food Systems: Policies, Institutions, and Knowledges on Small‐Scale Fishers and Energy Development

World Food Policy, Volume 12, Issue 2, November 2026.
ABSTRACT This study explores environmental justice issues in coastal food systems, focusing on conflicts between small‐scale fisheries and the energy sector due to differing goals in managing food and energy sources. It does so by examining the interdependence between institutions, policies, and different types of knowledge; key elements in building ...
