Shorebirds display great variation in mating systems and breed in dynamic environments that are increasingly subject to human threats worldwide. In order to adequately assess productivity and demography of shorebird populations, it is important to understand factors that influence patterns of parental care and reproductive success. The Black Oystercatcher (Haematopus...
Studies examining the effects of human disturbance on avian parental behavior and reproductive
success are fundamental to bird conservation. However, many such studies fail to also consider the influence of
natural threats, a variable environment, and parental roles. Our work examines interactive relationships of cyclical
(time of day, tide, temperature,...
Each community of scientists brings with it a set of values. Many of the urgent problems facing our planet require interdisciplinary science teams, but these teams often hold values that conflict. The Toolbox Dialogue Initiative (TDI) offers templates and guidance designed to help interdisciplinary teams of scientists recognize and address...
Red Crossbills (Fringillidae: Loxia curvirostra), irruptive finches which feed on conifer seeds, have long presented an evolutionary conundrum. Variable morphology and vocalizations in the species can be classified into several flight call types, which may be discrete lineages. The key conifer hypothesis suggests that each type diverged by specializing on...
Resident bull trout (Salvelinus confluentus) may be particularly vulnerable to human related disturbance, however very few studies have focused on resident bull trout populations. The abundance of bull trout is one measure of the strength and potential for persistence of a population. Habitat characteristics may influence resident bull trout abundance...
Development research and policy aim to improve household welfare by improving access to assets and economic opportunities (Besley & Burgess 2000; Deininger et al. 2003). In rural and agrarian contexts, these goals may be achieved by well-functioning markets for outputs, inputs, off-farm work, and credit. The status of these markets...
The marine and freshwater fishery resources of West Africa are some of the most productive in the world, and hold vast potential to provide economic prosperity and food security for the developing nations of that region. Nevertheless, the realized social benefits from fishery resources to West African nations have fallen...
