The Asia region harbors exceptional chondrichthyan (shark, ray, and chimaera) diversity but faces intense fishing pressure. The Important Shark and Ray Areas (ISRA) process provides a collaborative, evidence-based framework to identify critical habitats and inform spatial management. We assessed ISRAs across the Bay of Bengal, Southeast Asia, and the Northwest Pacific to characterize their extent, ecological significance, and...

Rationale The impact of cannabis use patterns on pain perception during abstinence remains unclear. Objectives This study examined whether cannabis use frequency and weekly delta-9-tetrahydrocannabinol (THC) exposure are associated with pain perception and circulating cannabinoid levels during biochemically verified brief abstinence. Methods Healthy adults ( N = 75; 29 females, 46 males; ages 21–55) reporting past-month cannab...

The combined effects of multiple pressures pose critical threats to marine ecosystems. As an initial spatial assessment of cumulative pressures in the Skagerrak, we mapped where multiple pressures coincided with sensitive habitats and species, combining recent spatial data sets on 20 pressures and 39 habitats and species. The spatial data were linked with sensitivity weights obtained with a novel partly data-driven method. We...

Complex landscapes are challenging to study because both the higher level contextual and interacting lower level mechanistic processes underpinning their ecological characteristics occur simultaneously. However, food‐web structures can provide process insight in such landscapes by identifying these processes in specific contexts. Here, we used stable isotopes to identify spatially separate resources and infer resource flows un...

Expansion of extractive industries to deep‐sea environments will lead to increased stresses on seafloor ecosystems. We examined changes in environmental parameters following direct and indirect experimental benthic disturbance using a modified plough on the Chatham Rise (∼450 m water depth), Aotearoa/New Zealand. Measurements included sediment community oxygen consumption (SCOC), nutrient fluxes, macro‐infauna community compos...

Growing global demand for deep‐sea resources may lead to increased pressure on benthic ecosystems. Here we examined changes in meiofaunal communities following an in situ physical disturbance experiment. A significant change in meiofaunal community structure in surface (0‐1 cm) and subsurface (1‐5 cm) sediments was observed immediately following the disturbance at both the directly and indirectly disturbed sites and adjacent p...

With the possibility of deep‐sea mining of mineral resources occurring, it is necessary to understand potential impacts on benthic communities. Previous simulated mining experiments revealed direct benthic impacts; however, indirect impacts of sedimentation are not well understood. A disturbance experiment was conducted on Chatham Rise, New Zealand, to assess the resilience of benthic communities to sedimentation that could re...

The cherry barb (Puntius titteya) is a staple of the ornamental aquaculture industry, with an estimated 60,000 individuals produced monthly in Florida, USA. On a commercial scale, small improvements in efficiency may yield considerable economic and operational benefits. This study investigated first-feeding protocols aimed at reducing the use of live Artemia spp. nauplii by evaluating microdiets (MDs) top-dressed with feed att...
