Provision of artificial shelter on beaches is associated with improved shorebird fledging success

open access: yes, 2011
Artificial chick shelters might improve productivity of beach-nesting birds threatened by anthropogenic disturbance. We investigated the efficacy of three different chick shelter designs against four criteria: accessibility to chicks over time, thermal ...

Review of terrestrial temporarily conserved areas in Canada, the United States, and Mexico

open access: yesConservation Biology, Volume 38, Issue 1, February 2024.
Abstract The establishment of protected areas is a cornerstone of conservation, but permanent protection could be inefficient or even impossible in some situations. We synthesized the literature on temporarily conserved areas (TCAs) across Canada, the United States, and Mexico.

Apparent survival of snowy plovers varies across years and between sexes in coastal Northern California [PDF]

open access: yes, 2020
Adult survival is one of the most influential vital rates affecting population growth of iteroparous organisms. Survival often varies annually due to environmental stochasticity.

Age-Related Survival and Behavior of Snowy Plover Chicks [PDF]

open access: yes, 2007
Precocial young often experience high mortality prior to achieving flight, especially in the first days after hatching. We quantified relationships between chick age, survival, behavior, and response to natural and anthropogenic danger for the threatened

Estimating Trends of Common Raven Populations in North America, 1966–2018 [PDF]

open access: yes, 2021
Over the last half century, common raven (Corvus corax; raven) populations have increased in abundance across much of North America. Ravens are generalist predators known to depredate the eggs and young of several sensitive species.

Synthesis of Nest Predation Impacts of Common Ravens on Sensitive Avian Species [PDF]

open access: yes, 2021
Decades of mounting scientific evidence have revealed that common raven (Corvus corax; raven) population numbers have been increasing across nearly all regions of their geographic range in North America.

Snowy Plover Activity in the Central Platte River Valley in May 2019 [PDF]

open access: yes, 2020
During five of eight site visits between 14 and 27 May 2019 we detected up to four Snowy Plovers (Charadrius nivosus nivosus) in the Central Platte River Valley (CPRV) near Mormon Island, Hall County, Nebraska, and recorded their behavior using an ...

Physiological, morphological and behavioural responses of self-feeding precocial chicks copying with contrasting levels of water salinity during development [PDF]

open access: yes, 2016
Combined physiological and behavioural responses to salt loads during development have rarely been studied in air-breathing vertebrates able to inhabit hypersaline habitats, but they may be of particular importance in understanding, for example, the ...

Regional evolutionary distinctiveness and endangerment as a means of prioritizing protection of endangered species [PDF]

open access: yes, 2015
Conservation is costly, and choices must be made about where to best allocate limited resources. I propose a regional evolutionary diversity and endangerment (RED-E) approach to prioritization of endangered species.
