Length‐Based Spawning Potential Ratio Assessment of Key Species From a Remote Recreational Fishery at Diego Garcia, Indian OceanNARA Subscribed
Recreational fisheries in remote regions often operate under limited regulation and data availability, presenting challenges for sustainable management. Diego Garcia, located within the Chagos Marine Protected Area, hosts a unique recreational reef fishery embedded within a highly protected environment. We assessed the stock status of five key species— Lutjanus bohar , L. gibbus , L. monostigma , Caranx melampygus , and Variol...
Diversity and functional group composition drive biogeographic patterns in marine biogenic structural complexityNARA Subscribed
Biogenic structural complexity is a key driver of biodiversity and ecosystem functioning, yet its ecological and environmental determinants remain poorly understood across broad biogeographic scales. Here, we conducted standardized 90‐day field experiments at 16 coastal sites, spanning a 41‐degree latitudinal gradient, using naturally assembled marine fouling communities on settlement panels. We measured rugosity as our metric...
Aims Biocrusts are common in arid ecosystems and perform critical ecosystem services. However, how abiotic (soil stability and aspect) and biotic factors (plant species canopies) interact to influence their community composition remains unclear. This study explores whether different plant species host distinct biocrust communities beneath their canopies, and whether these effects vary with slope aspect and soil stability acros...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
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...
Soil property controls on plasticiser, antioxidant and UV absorber additive degradation across a global soil gradientNARA Subscribed
Additives in agricultural plastics can leach into the surrounding soil during use or improper disposal. Their subsequent degradation rates directly regulate whether they persist and accumulate to levels with ecotoxicological effects or are rendered benign. However, which soil properties primarily regulate the degradation of additives remains unclear (e.g. soil carbon, pH, available nutrients, microbial biomass and community st...
We formally describe the association of fishes and anthozoans in epipelagic waters, extending this relationship to beyond the benthos. In situ observations and photographs of Aluterus schoepfii , Ariomma regulus , Caranx cf. latus and Brama spp. swimming alongside or holding larval tube anemones (Cerianthidae and Arachnactidae) and larval zoanthids (Sphenopidae) were made during blackwater SCUBA dives off Palm Beach, Florida,...
Evidence for successive breaching events by basking sharks Cetorhinus maximus (Lamniformes: Cetorhinidae)NARA Subscribed
Basking sharks were recorded breaching frequently off the coast of Co Clare, Ireland. The frequency and time between breaching events were analysed to determine any patterns in this behaviour. A total of 93 breaches of basking sharks were recorded over a 3-day period in September 2020. The mean number of breaches per hour, during a total observation period of 515 min, ranged from 6.0 to 15.3 with a mean ± SD of 9.2 ± 4.3 breac...
Whole Genome Sequencing Reveals How Plasticity and Genetic Differentiation Underlie Sympatric Morphs of Arctic CharrNARA Subscribed
Salmonids have a remarkable ability to form sympatric morphs after postglacial colonisation of freshwater lakes. These morphs often differ in morphology, feeding and spawning behaviour. Here, we explored the genetic basis of morph differentiation in Arctic charr ( n = 283) by first establishing a high‐quality reference genome and then using this in whole genome sequencing of distinct morphs present in two Norwegian and two Ice...
