Ivory poachers and poison: drivers of Africa's declining vulture populations

Year of publication
2015

Four species of African vultures have been recategorized as Critically Endangered, and two as Endangered, on the IUCN Red List. Their declining status is attributed partly to the impacts of widespread poisoning. Prior to poisoning of vultures was mostly associated with illegal predator control by livestock farmers, in which vultures were typically unintended victims.

Another Continental Vulture Crisis: Africa’s Vultures Collapsing toward Extinction

Year of publication
2015

Vultures provide critical ecosystem services, yet populations of many species have collapsed worldwide. We present the first estimates of a 30-year Pan- African vulture decline, confirming that declines have occurred on a scale broadly comparable with those seen in Asia, where the ecological, economic, and human costs are already documented.

Linking Conservation, Equity and Poverty Alleviation

Year of publication
2014

Biodiversity conservation that contributes towards poverty alleviation is a priority under the 2011–2020 Strategic Plan for the Convention for Biological Diversity (CBD). Protected areas are important for CBD signatories to deliver this objective and the 10th Conference of Parties encouraged members to ‘support initiatives on the role of protected areas in poverty alleviation’ (Decision X31)

Latitudinal variation in day length and working day length has a confounding effect when comparing nest attentiveness in tropical and temperate species

Year of publication
2014

During incubation, tropical passerines have been shown to have lower levels of nest attentiveness than their counterparts at north temperate latitudes, spending a higher percentage of daylight time off the nest. This difference has been interpreted as evidence of parental restraint; tropical birds allocate more time to daily self-maintenance, perhaps preserving their higher annual survival rates
