BIRDIE: A data pipeline to inform wetland and waterbird conservation at multiple scales

Frontiers in Ecology and Evolution, 2023
IntroductionEfforts to collect ecological data have intensified over the last decade. This is especially true for freshwater habitats, which are among the most impacted by human activity and yet lagging behind in terms of data availability.

Piscivore water bird diversity at freshwater tributaries of Zambezi River, Namibia

Koedoe: African Protected Area Conservation and Science
Piscivorous waterbirds enhance wetlands’ diversity and have been seen as bio-indicators of ecological conditions within ecosystems. In addition to their ecological contribution, to wetlands functions and ecosystem services, these birds have been reported

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years. [PDF]

Conserv Biol
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Duck Orbivirus and Egg Production: A Newly Identified Duck Orbivirus Is the Etiological Agent of Egg Production Decline in Chinese Breeder Ducks

Animal Research and One Health, EarlyView.
Field samples from breeder duck farms with egg‐production decline were subjected to viral detection, genome sequencing, and virus isolation. Experimental infection demonstrated that duck orbivirus (DORV) causes a significant and persistent reduction in egg production in breeder ducks.

Constructing Synthesizable Evaluations of Technical Interventions to Reduce Wildlife‐Caused Agricultural Losses 构建易用于证据整合的野生动物致农业损失缓解措施成效评估

Integrative Conservation, EarlyView.
A framework with eight key components to assess the effectiveness of technical measures to reduce wildlife‐caused agriculture loss. ABSTRACT Technical interventions to reduce wildlife‐caused agricultural losses (e.g., crops, livestock, and fisheries) are essential for human‐wildlife coexistence.

Seasonal and geographical variation in resident waterbird populations along the Paraguay River

El Hornero, 1996
I conducted 47 censuses of resident waterbirds at the Bahía de Asunción, a shallow "bay" of the Paraguay River, from October 1987 to October 1989. I also conducted four shipboard censuses of waterbirds along 859 km of the Paraguay River between Asunción

Recovery of great blue herons (Ardea herodias) within the Chesapeake Bay

The Journal of Wildlife Management, EarlyView.
We surveyed great blue herons throughout the tidal reach of the Chesapeake Bay in 2013 and mapped 423 colonies supporting 15,094 pairs. The population has increased more than four‐fold since the mid‐1970s. Colony size has declined. Invasion of colonies by bald eagles may be driving a change in spatial structure.

Waterbirds as Bioindicators of Environmental Conditions [PDF]

, 2012
We give examples of how waterbirds can be valuable indicators of changes in aquatic systems. Eutrophication is a widespread problem that can increase the food supply for some birds and hence increase their population size (e.g.

Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.
