Proximity to seabird colonies and water availability shape moss distributions in Antarctica Open
Understanding species distributions across Antarctica is crucial for biodiversity conservation under climate change, but continental‐scale analyses of key terrestrial species remain scarce. Here, we modelled distributions of 28 moss specie…

Accounting for the influence of dissimilarity gradients on community uniqueness Open
Compositional uniqueness has become increasingly relevant for understanding how local communities contribute to regional biodiversity. The most widely used metric is the Local Contribution to Beta Diversity (LCBD), which is typically regre…

Disturbance provides limited respite for native fish against invaders Open
Understanding how flow-related disturbance regimes influence species interactions is critical for conserving threatened species in freshwater ecosystems, where both the alteration of these regimes and the invasion of non-native species pos…

Asymmetric sharing of generalist pathogens between exotic and native plants correlates with exotic impact in communities Open
As exotic plants invade into a new range, they can escape from specialist enemies. However, they may support generalist enemies, including both native and introduced fungal pathogens, which creates the potential for spillover and apparent …

Factors influencing haulout behaviour of non-breeding weddell seals (Leptonychotes weddellii) at Cape Royds, Antarctica Open
The Weddell seal ( Leptonychotes weddellii ) is a fast-ice obligate species that plays an important role as both predator and prey within the high-latitude, coastal Southern Ocean. Weddell seals are affected by pressures of marine resource…

Understanding temporal variability across trophic levels and spatial scales in freshwater ecosystems Open
A tenet of ecology is that temporal variability in ecological structure and processes tends to decrease with increasing spatial scales (from locales to regions) and levels of biological organization (from populations to communities). Howev…

Climate change impacts on Aotearoa New Zealand: a horizon scan approach Open
Many of the implications of climate change for Aotearoa (New Zealand) remain unclear. To identify so-far unseen or understudied threats and opportunities related to climate change we applied a horizon-scanning process. First, we collated 1…

A metasystem approach to designing environmental flows Open
Accelerating the design and implementation of environmental flows (e-flows) is essential to curb the rapid, ongoing loss of freshwater biodiversity and the benefits it provides to people. However, the effectiveness of e-flow programs may b…

Diversity–stability relationships across organism groups and ecosystem types become decoupled across spatial scales Open
The relationship between biodiversity and stability, or its inverse, temporal variability, is multidimensional and complex. Temporal variability in aggregate properties, like total biomass or abundance, is typically lower in communities wi…
