Climate‐driven alterations in sea‐ice dynamics and shifting fishing activity are reshaping ecosystems across the Arctic and Antarctic, yet conservation‐relevant information for chondrichthyans (sharks, rays, and chimaeras) remains limited. We present the first assessment of Important Shark and Ray Areas (ISRAs) across Polar Waters, integrating species distributions, extinction risk, critical habitat evidence, spatial protectio...
Anadromous Arctic char ( Salvelinus alpinus ) and northern form Dolly Varden ( Salvelinus malma malma ) are highly valued by Indigenous communities in northern Canada. Rapid, ongoing environmental changes are affecting populations of both of these iteroparous species, and understanding variability in life‐history tactics is essential for assessment of current and future impacts. The Coppermine River, Nunavut, provides a unique...
Neural bottlenecks: axon count, distribution, and conduction in the Manduca sexta neck connectiveNARA Subscribed
Large flying insects precisely control fast maneuvers, a demanding task made more difficult by the limitation that all information between the brain and body is transmitted through a single transmission line, the neck connective. Despite this neuroanatomical structure constraining both the amount and timing of all information between the brain and body, little is known about how severe these bottlenecks are. We sought to under...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
