The projected risk of plant invasions on the peri‐Antarctic islands under climate change

Ecography, EarlyView.
The peri‐Antarctic islands have largely been shielded from alien plant species due to low human pressure, limited introduction pathways, and local harsh climates. However, climate change is expected to lower these barriers. We assess the vulnerability of 12 peri‐Antarctic islands to invasion by 2220 plant species invasive in at least one region of the ...

Cryptic diversity in smooth-shelled mussels on Southern Ocean islands: connectivity, hybridisation and a marine invasion

Frontiers in Zoology, 2019
Background Large numbers of endemic species inhabit subantarctic continental coasts and islands that are characterised by highly variable environmental conditions.

Phylogenetic structure of conifers in regional floras in relation to climate and environmental heterogeneity worldwide

Ecography, EarlyView.
Despite having only about 670 species worldwide, conifers are one of the ecologically and economically most important plant groups. They have a rich fossil record and previous studies have shown that their current diversity is the result of past radiations, extinction, and dispersal events, restricting many genera to either the Northern or Southern ...

Mesospheric Ozone Depletion during 2004–2024 as a Function of Solar Proton Events Intensity

Atmosphere
Solar proton events (SPEs) affect the Earth’s atmosphere, causing additional ionization in the high-latitude mesosphere and stratosphere. Ionization rates from such solar proton events maximize in the stratosphere, but the formation of ozone-depleting ...

A global latitudinal decline in breeding site fidelity emerges from a single biome

Ecography, EarlyView.
Species that breed in multiple years can either return to the same location to reproduce between seasons or disperse to a different location. Previous studies have shown that breeding site fidelity varies with species‐ and individual‐specific traits, but much of the observed variation remains unexplained.

Human pressure, habitat heterogeneity and species traits jointly determine the level of dark diversity in coastal fish communities

Ecography, EarlyView.
Understanding how anthropogenic pressures and environmental gradients shape coastal fish communities is a central question in biogeography and marine conservation. Yet, the set of species expected to occur at a site given ecological conditions but being absent – the so‐called dark diversity – has received far less attention than observed species, even ...
