Genetic studies have differentiated three subspecies of humpback whales: Megaptera novaeangliae novaeangliae in the North Atlantic, M. n. australis in the Southern Hemisphere and M. n. kuzira in the North Pacific. However, these analyses did not include samples from the Arabian Sea humpback whale population (ASHW). Historic, behavioural, and previously published genetic data suggested that ASHWs are a discrete, isolated and re...
Mercury (Hg), and specifically methylmercury (MeHg), is a contaminant of global concern to humans and wildlife, but there is still limited understanding of its effects on many taxa. Amphibians are closely associated with water, where Hg is converted to MeHg, and high concentrations of MeHg can reduce survival of amphibians in the wild. However, limited non-lethal proxies exist for estimating MeHg bioaccumulation in amphibian l...
Nutrient Enrichment Increases Grassland Biomass Sensitivity to Interannual Precipitation VariationNARA Subscribed
Primary production underpins much of ecosystem functioning and is often limited by nutrient and water availability. Ongoing global increases in nutrient inputs and interannual precipitation variability are thus likely to impact primary production, with unclear consequences for interannual variability in plant biomass. We used data from 35 grasslands in the Nutrient Network coordinated fertilization experiment to test if nutrie...
Conservation implications of low contemporary connectivity along the Mid‐Atlantic Ridge in hydrothermal vent gastropodsNARA Subscribed
Polymetallic sulfide deposits produced at hydrothermal vent fields are targets for mining exploitation along the Mid‐Atlantic Ridge, threatening the functioning and resilience of vent ecosystems that provide multiple ecosystem services. Knowledge about connectivity between vents will inform conservation practices. The present‐day genetic structure and demographic history of the two vent‐dwelling gastropod species, Lepetodrilus...
Constraining eruption timing and duration at Taranaki volcano, New Zealand, using Late Holocene stalagmitesNARA Subscribed
Robust hazard assessment at dormant stratovolcanoes requires high-resolution eruption chronologies, yet these are often limited by incomplete proximal deposits and poorly constrained ages. Speleothems can preserve tephra particles and volcanogenic trace element signals datable using high-precision 230 Th/U chronologies. However, accurate eruption timings are affected by transfer delays of volcanogenic signals in distal cave sy...
Macrourid species constitute the main bycatch in Southern Ocean toothfish longline fisheries. We report the first confirmed record of Whitson's grenadier, Macrourus whitsoni , in the South Georgia toothfish fishery. Mitochondrial cox1 DNA barcoding confirmed its presence in bycatch samples collected around South Georgia and the northern South Sandwich Islands, with approximately 1% divergence from its congener, M. caml . Haplo...
Individual Trees Respond to 40 Years of Climate Change Through Leaf Functional Trait AcclimationNARA Subscribed
Forests are vital for regulating climate and sustaining biodiversity, but climate change threatens their ability to do so, especially in the tropics. Our knowledge of how tropical forests and their constituent trees will respond to changes in climate is largely based on functional trait studies; however, few previous studies have investigated trait changes within individual tropical trees across decades, limiting our ability t...
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...
