On the tip of the tongue: natural history observations that transformed shorebird ecology
A new field of shorebird feeding ecology has been opened, stemming directly from natural history observations of previously overlooked morphological and behavioral features. We describe how the pieces of this puzzle were assembled to reveal a fascinating

Measuring Bird Morphology From Field Photographs
We evaluated a digital photography approach based on the pinhole camera model to estimate bird morphometric traits from single images, testing its accuracy under controlled conditions and across 37 species photographed in the field. Photographic measurements showed strong agreement with museum and database‐derived traits (ρ = 0.82–0.95), with wing and ...

The management of avian populations at risk requires accurate estimates of vital rates across age and sex classes to effectively identify the most vulnerable demographic and support conservation actions. In the endangered Red Knot (Calidris canutus rufa),

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

Assessing the risk of an aquaculture development on shorebirds using a Bayesian belief model
One of the largest Ramsar-designated wetlands in New Zealand is located at Miranda, in the Hauraki Gulf, at the head of a large sheltered embayment (the Firth of Thames).

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 ...

Various animal species worldwide use artificial environments for reproduction, a suitable alternative to dwindling native habitats. An artificial lake system established in the core zone of the Al Marmoom Desert Conservation Reserve, Dubai, United Arab ...

Biodiversity and bird welfare in evaluation of tourism impact and sustainability in arid environment
Abstract Nature‐based tourism is rapidly expanding in arid regions, raising concerns about its long‐term sustainability and potential impacts on biodiversity. However, empirical evidence evaluating its effects on both species diversity and animal welfare remains limited.

Demographic Histories and Genome-Wide Patterns of Divergence in Incipient Species of Shorebirds
Understanding how incipient species are maintained with gene flow is a fundamental question in evolutionary biology. Whole genome sequencing of multiple individuals holds great potential to illustrate patterns of genomic differentiation as well as the ...
