Pollinator decline, driven primarily by habitat degradation, has the potential to reduce the quantity and quality of pollinator-dependent crops produced across the world. Vitellaria paradoxa , a socio-economically important tree which grows across th

Publikováno v: Ibis. 160:805-815
Populations of long-distance migrant birds are declining but it is unknown what role land cover change in non-breeding areas may be playing in this process. Using compositional analysis, we assessed habitat selection by one such migrant, the Wood War

Publikováno v: Bird Study. 63:459-469
Capsule: Wood Warblers Phylloscopus sibilatrix showed significant selection for tree species and woodland characteristics at staging and wintering sites in sub-Saharan Africa. Aims: To investigate home range size, habitat and tree species selection o
