Waterbird nest survival derived from drone surveys

open access: yesJournal of Field Ornithology
Drone surveys provide accurate estimates of nest abundance and survival for ground-nesting waterbird species, but drones have not been used to estimate survival for waterbirds nesting in a canopied swamp habitat. We compared nest survival of Snowy Egret (

Fusion or Confusion? Assessing the Impact of Visible‐Thermal Image Fusion for Automated Wildlife Detection

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study evaluates the performances of synchronous aerial visible (VIS) and thermal infrared (TIR) imagery for detecting great blue heron (Ardea herodias) nests and individuals using a YOLO11n model. VIS and TIR images were automatically aligned using deep learning, and both early and late fusion approaches were tested.

Factors influencing long-term and seasonal waterbird abundance and composition at two adjacent lakes in Zimbabwe [PDF]

open access: yes, 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 ...

Remote Sensing‐Based Identification of Habitat Loss for Herbivorous Waterbirds Driven by Wetland Inundation Alterations

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We present a deep learning framework integrating remote sensing and SHAP interpretation to map 22‐year habitat dynamics of herbivorous waterbirds in Dongting Lake. Results show nearly 50% habitat loss, driven primarily by hydrological recession timing rather than static inundation extent.

Mediterranean waterbird functional diversity and traits

open access: yes, 2018
These are three datasets. Div.alfa.csv describes functional diversity indexes for wintering and breeding waterbird communities on 11 Mediterranean wetlands from 1990 to 2017.

Spatial scales matter in designing buffer zones for coastal protected areas along the East Asian-Australasian Flyway

open access: yesGlobal Ecology and Conservation
Coastal protected areas are increasingly threatened by urbanization, posing significant risks to wetland biodiversity. Consequently, the recognition of buffer zones as essential for reducing anthropogenic impacts on protected areas has grown.

Cotton Farming Pesticides Affect Ileal Microbiota Activity and Expression of Virulome but Not Resistome or Metabolic Pathways in a Sedentary Wild Passerine

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The increased use of agrochemicals to enhance crop production has had detrimental environmental effects including implication in the sharp decline of North American farmland‐breeding birds. Here, using a combination of deep shotgun metatranscriptomics and pesticide exposure data, we sought to assess whether exposure to cotton (Gossypium spp ...

Multi-scale factors revealed contrasting impacts on Waterbird composition and Beta diversity across wetlands in an Afrotropical landscape

open access: yesGlobal Ecology and Conservation
Global loss and human-induced degradation of wetlands are presumed to impact waterbirds. To understand how human activities and habitat features drive waterbird species composition, there is need to understand beta-diversity and its components of ...

Estimating crippling loss from hunting with multistate models: a case study on northern bobwhites

open access: yesWildlife Biology, EarlyView.
Hunting as a recreational pursuit provides an important ecosystem service worldwide. Harvest management plays a vital role in regulating wildlife take to ensure long‐term population sustainability and meet value‐based objectives (e.g. hunter satisfaction). However, managers rarely have complete control or observability of harvest mortality.

Factors influencing wintering turfgrass field use in Atlantic brant

open access: yesWildlife Biology, EarlyView.
Atlantic brant Branta bernicla hrota increasingly use turfgrass fields, such as baseball fields and golf courses, throughout their wintering range. Most studies have focused on their primary food source, submerged aquatic vegetation, while studies of other goose species worldwide have examined field use in different contexts, including agricultural ...
