We present outcomes from our 17th horizon scan of issues potentially impacting global biodiversity conservation in the next decade. Issues are novel, or represent a significant step-change in impact, and […]
Radiocarbon-dated fossils indicate woolly mammoths were extirpated from mainland Beringia around 13 000 years ago. However, environmental DNA in permafrost suggests small “cryptic“ populations survived into the Holocene. Resolving this discrepancy […]
Surface warming in the polar regions has important consequences for the stability of the lowest layers of the atmosphere and for atmospheric vertical movement. Here, using ERA5 reanalysis data and […]
Microorganisms often occur in association with macroalgae, with the term “phycosphere” referring to the seaweed surface where they may be present. Phycosphere represents a poorly explored niche of marine diversity, […]
Understanding how deleterious mutations affect fitness is central to evolutionary and conservation biology. However, most empirical studies rely on inbreeding as a proxy for the mutation load, overlooking the substantial […]
Conserving marine species effectively requires spatially and temporally explicit knowledge of their abundance and distribution for assessing potential impacts (e.g., from fishery bycatch, anthropogenic sound, ship strikes) over different spatial […]
1. Amid increasing anthropogenic pressures on ecosystems, standardised biodiversity monitoring is critical for assessing biodiversity change. Marine hard-bottom habitats, though ubiquitous and biodiverse, present challenges for biodiversity monitoring due to […]
Pumice rafts derived from submarine eruptions can remain afloat for months or even years, traveling thousands of kilometers on ocean currents. These natural phenomena disperse marine organisms and provide important […]
Antarctic sea ice showed a profound, step-wise reduction around 2016-2017, but the scarcity of modern time series means that we know very little about how Southern Ocean biota have responded. […]
As top predators, leopard seals (Hydrurga leptonyx) have a key role in Southern Ocean ecosystems. For example, this species has driven the local collapse of Antarctic fur seals (Arctocephalus gazella) […]
Background: Pelagic seabirds forage over vast areas, and their movements and diet provide valuable insights into environmental conditions that are otherwise difficult to observe. Snow petrels Pagodroma nivea forage largely […]
The surface texture of bird eggshells differs remarkably between species and is thought to play a substantial role in providing physical and microbial protection for the developing embryo. We used […]
