Ecosphere, 2016 In the Southern Ocean, wide‐ranging predators offer the opportunity to quantify how animals respond to differences in the environment because their behavior and population trends are an integrated signal of prevailing conditions within multiple marine ...

Oikos, EarlyView.Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

The influence of multiple stressors on the spatial distribution of corals
People and Nature, EarlyView.Abstract Coral reef ecosystems are widely threatened by global change, yet the cumulative impacts of multiple interacting stressors remain difficult to quantify over space and time. We evaluate how long‐term artisanal fishing effort, blast fishing, human population density and marine protected areas (MPAs) interact with biophysical and seascape ...

The impact of Arctic sea‐ice loss on winter weather in the British Isles
Quarterly Journal of the Royal Meteorological Society, EarlyView.Arctic sea‐ice loss shifts the North Atlantic jet and storm track equatorward, and results in a more negative North Atlantic Oscillation and more positive East Atlantic and Scandinavian patterns. Strong extratropical cyclones weaken and become less frequent for the British Isles, but there is model disagreement for precipitation, surface winds, and ...

Can tropical cyclones exist near the Equator?
Quarterly Journal of the Royal Meteorological Society, EarlyView.Schematic showing how a developed TC responds to reduced Coriolis parameter (f). Zero‐f lowers inertial stability and increases agradient force, enhancing radial inflow at lower levels. Stronger inflow deepens the inflow layer and promotes convergence, intensifying convection and downdrafts in outer rainbands.

A regional implementation of a mixed finite‐element, semi‐implicit dynamical core
Quarterly Journal of the Royal Meteorological Society, EarlyView.A regional version of a new dynamical core with an iterated semi‐implicit time discretisation and mixed finite‐element spatial discretisation is described. This involves modifying the mixed‐system and Helmholtz‐preconditioner equations to use lateral boundary condition (LBC) data specified by a driving model.

On the β$$ \beta $$‐effect in the baroclinic instability of a continuously stratified atmosphere
Quarterly Journal of the Royal Meteorological Society, EarlyView.We solve the quasi‐geostrophic equation numerically to analyze baroclinic instability in a continuously stratified atmosphere. On the β$$ \beta $$‐plane, deviations from classical models alter instability growth rates and modal structures, leading to the emergence of unstable lobes and a stable region at very large wavelengths.

Quarterly Journal of the Royal Meteorological Society, EarlyView.We present a compatible finite‐element discretisation of a general formulation of moist shallow‐water equations, with the aim of providing a simple model to advance understanding of physics–dynamics coupling. We detail set‐ups and show three moist shallow‐water test cases in four different model formulations. The results demonstrate differences between
