The costs of extra‐pair behaviours in birds

Biological Reviews, EarlyView.
ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.

Impacts of reclamation and aquaculture on the wintering waterbird assemblage at a floodplain lakeshore based on multidimensional diversity

Global Ecology and Conservation
The floodplain lakeshores have pronounced hydrological and topographical gradients, high habitat heterogeneity, and abundant food sources, providing suitable habitats for wintering and stopping waterbirds.

Influence of land use change on the waterbird community of Sihwa Lake, Republic of Korea

Avian Research, 2020
Background Land use and development alter mudflat and wetland habitat availability, although mudflats and wetlands provide important stopover habitats for shorebirds during the spring and autumn migrations and support communities of ducks and geese ...

Comparing autumn duck use of intensely managed wetlands in Michigan using a novel approach

The Journal of Wildlife Management, EarlyView.
Camera traps, a relatively novel method for assessing waterfowl use of wetlands, show ducks in southeastern Michigan are influenced by hunting disturbance, vegetation type, season progression, and diel period. Abstract Socioeconomic value derived from duck hunting has contributed to autumn habitat use becoming a particular focus for the natural ...

The Association of Pregnancy and Scurvy in Indigenous Women and Their Children From the Late Holocene in California (USA)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Limited evidence of nutritional deficiencies has been identified in bioarchaeological studies of Native California populations, although isotopic and ethnohistoric research provides evidence of regional, seasonal, and cultural variability in food shortages.

Effects of flyway-wide weather conditions and breeding habitat on the breeding abundance of migratory boreal waterbirds [PDF]

, 2017
Anthropogenic habitat loss and climate change are among the major threats to biodiversity. Bioclimatic zones such as the boreal and arctic regions are undergoing rapid environmental change, which will likely trigger changes in wildlife communities ...

From the brink of extinction to regulation: northern Europe's white‐tailed eagles now face density dependence and climate constraints after rapid population growth

Oikos, EarlyView.
Population growth reflects the combined influence of regulation and density‐independent factors operating through demographic processes. Under exceptional circumstances (e.g. populations recovering from near‐extinction), growth may initially be weakly regulated but typically slows as negative density dependence (NDD) sets in.
