Ecosystem services provided by waterbirds

Biological Reviews, 2013
ABSTRACT Ecosystem services are ecosystem processes that directly or indirectly benefit human well‐being. There has been much recent literature identifying different services and the communities and species that provide them. This is a vital first step towards management and maintenance of these services.

Exploring sources of uncertainty in the estimate of waterfowl harvest in the United Kingdom

Wildlife Biology, EarlyView.
There is an urgent need to gather data on harvest rates of waterbirds in Europe to assess the sustainability of hunting. Estimates of total waterbird harvest in the United Kingdom (UK) and the relative harvest of different huntable species come from two separate surveys, the Value of Shooting (PACEC 2014) and National Gamebag Census (NGC), and these ...

Vegetation and inundation characteristics of waterbird breeding sites in the Murray–Darling Basin, Australia [PDF]

Context. The Murray–Darling Basin serves as a crucial habitat for aggregating waterbirds; however, decades of large-scale regulation of rivers and water resources have adversely affected waterbird breeding in the Basin. Aims.

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

Global 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 ...

Patterns of inter- and intraspecific nest dispersion in colonies of gulls and grebes based on drone imagery

Journal of Field Ornithology, 2022
Colonial nesting of both single and mixed-species assemblages is common across avian taxa. Coloniality may provide fitness advantages such as reduced nest predation through predator swamping, early warning of predators, or nest stability, or could simply

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

Wildlife 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.

Population trends and community composition of migratory waterbirds in three emerging wetlands of global significance in southwestern Bengal, India

Journal of Threatened Taxa, 2016
We studied the diversity, abundance and population trends in three flourishing wetlands of southern Bengal over 16 years.  These wetlands constituted a major shift from the present scenario of overall wetland deterioration, including monotonous declines ...

Availability bias and responsive movement during ground‐based wildlife surveys revealed by concurrent thermal drone surveys

Wildlife Biology, EarlyView.
Methods to estimate abundance from unmarked populations of animals are widely used because of their efficiency and presumed accuracy. These methods account for imperfect detection by comparing observed data against the assumed distribution of the entire population.
