Impacts of land-use change on bat functional diversity with implications for resilience of West African agroecosystems

Cecilia Montauban, Adam J.M. Devenish, Ivana Budinski, Nathaniel N. D. Annorbah et autres

Agricultural expansion is a major driver of global biodiversity loss, reshaping species assemblages and disrupting ecological functions essential for ecosystem resilience. These effects are most pronounced in tropical forests yet remain poorly understood for many taxa, including bats that provide key ecosystem …

Assessing distribution, abundance and impacts of trade and habitat change in western populations of African grey parrot (psittacus erithacus)

Nathaniel N. D. Annorbah

In Ghana, many large avian frugivores face very serious threats, including habitat loss, hunting, and capture for the pet trade. However, basic ecological information is lacking for most species including the heavily-traded Grey Parrot Psittacus erithacus. The aim of my PhD was …

Shifting baselines increase the risk of misinterpreting biodiversity trends

Ariane Dellavalle, Adam J. M. Devenish, Crinan Jarrett, Nathaniel N. D. Annorbah et autres

Ecological studies quantifying the impact of land‐use change on biodiversity may be sensitive to the choice of reference points – or baselines – particularly when sampling across human land‐use gradients and other space‐for‐time comparisons. Much depends on whether the chosen baseline has …

Extreme migratory connectivity and apparent mirroring of non-breeding grounds conditions in a severely declining breeding population of an Afro-Palearctic migratory bird

Máire Kirkland, Nathaniel N. D. Annorbah, Lee J. Barber, J. H. Black et autres

Understanding the distribution of breeding populations of migratory animals in the non-breeding period (migratory connectivity) is important for understanding their response to environmental change. High connectivity (low non-breeding population dispersion) may lower resilience to climate change and increase vulnerability to habitat loss …

Abundance and Breeding Ecology of Critically Endangered Vultures in Mole National Park, Ghana

Sandra Goded, Nathaniel N. D. Annorbah, Olivier Boissier, Kristen M. Rosamond et autres

Los buitres están entre las especies más amenazadas en África, con varias especies en peligro crítico de extinción que sobreviven principalmente o sólo en áreas protegidas. Las disminuciones de buitres del oeste de África están correlacionadas con pérdidas pronunciadas de hábitat natural …

Conservation status and threats to lovebirds: knowledge gaps and research priorities

Sascha Dueker, Sandi Willows‐Munro, Michael R. Perrin, YILMA DELLELEGN ABEBE et autres

Lovebirds (genus Agapornis of family Psittaculidae) are a group of small, colourful parrot species endemic to sub-Saharan Africa and Madagascar, two-thirds of which are considered to have declining populations. Effective conservation efforts are hampered by a lack of information, particularly for species …

AVONET: morphological, ecological and geographical data for all birds

Joseph A. Tobias, Catherine Sheard, Alex L. Pigot, Adam J. M. Devenish et autres

Functional traits offer a rich quantitative framework for developing and testing theories in evolutionary biology, ecology and ecosystem science. However, the potential of functional traits to drive theoretical advances and refine models of global change can only be fully realised when species-level …
