Downscaling with AI reveals the large role of internal variability in fine-scale projections of climate extremesNARA Subscribed
The computational cost of dynamical downscaling limits ensemble sizes in regional downscaling efforts. We present a generative-AI approach to greatly expand the scope of such downscaling, enabling fine-scale future changes to be characterised including rare extremes that cannot be addressed by traditional approaches. We test this approach for New Zealand, where heterogenous regional climate effects are anticipated. End-of-cent...
Aim We aim to reconstruct the phylogeographical history of Musa acuminata subsp. banksii across New Guinea and Australia and to test whether its occurrence in Australia results from ancient natural dispersal or recent human‐mediated translocation. Location New Guinea and northern Australia (Sahul Shelf). Taxon M. acuminata subsp. banksii (F.Muell.) N.W.Simmonds (Musaceae). Methods We generated genome‐wide single nucleotide pol...
Anthropogenic Effects, Not Climatic Factors, Are Correlated With Holocene Population Expansion of an Insular Bee FaunaNARA Subscribed
Aim Remote island systems with small landmasses and reliable estimates of human occupancy can be ideal models to disentangle the roles of global climatic changes and local human occupation on biota. Here, we explored this with demographic reconstructions of native, ground‐nesting bees with non‐specialised floral visitation habits to infer changes in effective population size ( N e ). Location Viti Levu, Fiji, South West Pacifi...
Understanding how marine species tolerate ocean acidification (OA) is critical for predicting biological responses to ocean change, as well as impacts on the ecosystems and industries that rely upon them. Snow crab ( Chionoecetes opilio ) are both a major fishery resource in the Bering Sea and an important component of high-latitude marine food webs. Experimental work suggests that snow crab are relatively tolerant of OA, but...
We report the first live in situ observations of the iconic goblin shark ( Mitsukurina owstoni ) on a seamount near Jarvis Island in 2019 and on the slope of the Tonga Trench in 2024. Past observations are restricted to specimens hauled to the surface, resulting in limited knowledge of this species' ecology. These observations extend its known geographic and depth range considerably, and extend the depth range of lamniform sha...
