Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Native habitat affinities predict fish invasions with post‐invasion habitat shifts

Journal of Animal Ecology, EarlyView.
Initial invasion success is gated by native pre‐adaptations, but post‐invasion establishment is characterized by habitat shifts. We demonstrate that forecasting risk based solely on native niches severely underestimates future ecological impacts, and we provide an empirically validated watchlist of future invaders.

Genomic Content in Avian Haemosporidian Parasites Suggests Co‐Regulation of Apicoplast and Mitochondrial Nucleoids

Integrative Zoology, EarlyView.
Apicoplast genomic content and mitochondrial genomic content were found to be strongly correlated (rho = 0.93) for infections going from low to high. Apicoplast and mitochondrial genomic content were deemed as more predictive factors of parasitemia for different infection intensities.

Drivers of Mouse Plagues: Exceptional Rainfall Following Prolonged Drought Triggers Mouse Plagues in Southeastern Australia

Integrative Zoology, EarlyView.
This study identified a specific sequence of an extended drought followed by exceptional rainfall as a necessary precursor for mouse plagues in southeastern Australia. Long‐term rainfall anomalies interact with ecological processes to reset population dynamics, creating conditions that support rapid mouse population growth following periods of ...

Forecasting ecological trajectories from ecological dynamic regimes to improve resilience analysis

Methods in Ecology and Evolution, EarlyView.
Abstract The ecological dynamic regime (EDR) framework was recently proposed as an alternative to equilibrium‐based approaches for assessing ecological resilience in empirical systems, explicitly incorporating dynamic regimes as a reference for assessing the system's deviation during disturbances.

The superposition method for the reconstruction of food webs

Methods in Ecology and Evolution, EarlyView.
Abstract Understanding trophic positions is essential for analysing complex food webs. While calculating these positions can be straightforward when feeding relationships and their proportions are known, determining diet coefficients traditionally requires substantial time and effort.
