Cooperative breeding behaviors in the Hawaiian Stilt (Himantopus mexicanus knudseni)
Ecology and Evolution, 2021 Cooperative breeding, which is commonly characterized by nonbreeding individuals that assist others with reproduction, is common in avian species. However, few accounts have been reported in Charadriiformes, particularly island‐nesting species.

Different demographic drivers of recovery in two adjacent populations of a long‐lived bird of prey
Oikos, EarlyView.Understanding the demographic mechanisms underlying population decline or recovery is critical for conservation and management, yet similar population trends may arise from very different underlying processes. Comparing populations of vulnerable species groups like long‐lived raptors in different environments can reveal how species respond to change ...

Factors influencing long-term and seasonal waterbird abundance and composition at two adjacent lakes in Zimbabwe [PDF]
, 2012 The spatial and temporal structures of waterbird communities are dynamic and complex with many driving factors. We used long-term waterbird census data at two lakes in Zimbabwe to explore the ecological and anthropogenic drivers of waterbird community ...

Diversity and Distributions: A journal of biological invasions and biodiversity, 2021 Understanding how biotic communities are spatially distributed is essential for biodiversity conservation in human‐modified landscapes. The large‐scale subsidence wetlands generated by underground coal mining in China have been increasingly used by large

River Research and Applications, EarlyView.ABSTRACT Terminal basins provide unique aquatic environments that are often highly sensitive to streamflow contributions, making them a focal point for environmental water management. However, the water needs for terminal lake, wetland, and river ecosystems, and how they relate, remain a fundamental knowledge gap that constrains our ability to ...

Big Bird: A global dataset of birds in drone imagery annotated to species level
Remote Sensing in Ecology and Conservation, EarlyView.Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

Effects of Waterbird Herbivory on Dominant Perennial Herb Carex thunbergii in Shengjin Lake [PDF]
, 2022 Abundant food resources in riparian zones provide efficient foraging sites for waterbirds. Herbivory is a key ecosystem process that has widely recognized effects on primary production and vegetation structure and composition.
