How to reduce sampling error in species population monitoring: from theory to methods

Ecography, EarlyView.
Progress towards national and international targets to halt and reverse declines in species' abundances will be assessed using multispecies indicators (MSIs). A distinction must be drawn between two MSIs. One is the ideal, but unobserved, MSI that would have been measured had all species and sites within the scope of the target been sampled.

Increase in plant productivity in the tundra in Sweden is not related to increasing presence of warm‐adapted vascular plant species

Ecography, EarlyView.
Over the past decades, Arctic and alpine biomes have warmed faster than the global average. Substantial vegetation changes have been reported as a response to this warming, including increased productivity and the spread of warm‐adapted (thermophilic) species that are less resistant to grazing pressure into higher latitudes and altitudes.

Latitudinal effect on the structure of snake–prey interaction networks is mediated by snake species richness

Ecography, EarlyView.
Despite the growing number of studies on trophic networks in recent decades, there are still important gaps in our understanding of how these networks are structured across broad environmental gradients. These gaps are even greater in some groups of terrestrial vertebrates, such as snakes, requiring a cohesive synthesis of their broader trophic ...

Climate‐driven resource availability drives medium‐ and broad‐scale temporal changes in owl–prey interactions over 24 years in a semi‐arid ecosystem

Ecography, EarlyView.
Predator–prey interactions are vital to ecosystem functioning but may be disrupted by climate change. We investigated a food‐web network involving three owl species over 24 years in a semi‐arid ecosystem at Bosque Fray Jorge National Park, Chile.

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.

Global distribution of avian plumage coloration and patterning: the relative influence of climate, ecology, and sexual selection

Ecography, EarlyView.
Animal coloration exhibits substantial biogeographic variation, reflecting complex adaptations to both abiotic and biotic environments. Although the evolutionary mechanisms underlying avian plumage coloration have been widely studied, geographic variation in plumage patterning has received far less attention.

Rising, falling, stalling: complex biodiversity trajectories in English rivers

Ecography, EarlyView.
Freshwater ecosystems face intense anthropogenic pressures. Yet in parts of Europe, including the UK, studies have documented widespread increases in macroinvertebrate diversity following investments to improve water quality. More recent analyses, however, suggest that these gains have slowed, plateaued, or even reversed. Despite increasing recognition

Continental scale metagenomics reveals Microcystis‐induced synchrony among aquatic taxa is exacerbated by trophic cascades

Ecography, EarlyView.
Harmful Microcystis proliferation severely threatens aquatic ecosystems globally, but its impacts on food‐web stability remain poorly understood. Here, we analyzed 1309 metagenomic samples from freshwater ecosystems across China to investigate how Microcystis abundance affects synchrony among taxa in multi‐trophic food webs (from bacteriophages to ...
