At the tipping point: Can biodiversity and rural livelihoods endure uncontrolle...

Our commentary explores the increase in cashew cultivation across West Africa, drawing attention to its impacts on biodiversity and livelihoods. We summarize the issue regionally, then showcase Guinea-Bissau, where we unravel the dynamics between cashew expansion, habitat and biodiversity loss, and livelihoods. Finally, we propose concrete policy measures encompassing strengthened conservation, sustainable land...

Not in wilderness: African vulture strongholds remain in areas with high human ...

Vultures constitute an important functional group in many ecosystems, providing crucial ecosystem services both in natural and humanized environments. These scavengers are facing massive declines worldwide, but in several African countries virtually nothing is known on populations' status and threats, hampering the development of adequate conservation strategies. In Guinea-Bissau, globally important populations...

Ecology and behaviour of Palm-nut Vultures Gypohierax angolensis in the Bijagós...

Populations of many vulture species have undergone substantial declines. In Africa, 82% are threatened and although research on vultures has increased, the biology and ecology of several species is still poorly known. The Palm-nut Vulture Gypohierax angolensis has peculiar ecological characteristics, feeding on palm fruits, associated with the aquatic environment and taking a wide variety of prey. It has been o...

Nest-site characteristics and aspects of the breeding biology of the endangered...

Timneh Parrots Psittacus timneh are endemic to the moist forests of West Africa. Concerns over rapid declines in populations due to overharvesting for the pet trade and forest loss prompted the species’ categorisation as Endangered on the IUCN Red List of Threatened Species in 2016. Despite these threats, few data exist on their biology in the wild, impeding the development of effective conservation initiatives...

Status of birds of prey in Guinea-Bissau: First assessment based on road surveys

Several studies have reported marked declines in populations of birds of prey across the African continent, including West Africa. However, there are still regions of which virtually nothing is known, as is the case for Guinea-Bissau. Because birds of prey play important roles in ecosystems and several species are threatened, it is important to establish baseline knowledge on their status. This is the first stu...
