Locomotor, ecological and phylogenetic drivers of skeletal proportions in frogs
Journal of Anatomy, Volume 243, Issue 3, Page 404-420, September 2023., 2023 This study investigates the link between skeletal anatomy and locomotor mode, habitat type and evolution in frogs, shedding new light on how functional demands impact morphology. Sacral expansion is the strongest driver of morphological variation. Locomotor mode has a more significant impact on morphology than habitat type and phylogenetic history ...

Savanna vegetation increase triggers freshwater community shifts
Global Change Biology, Volume 28, Issue 23, Page 7023-7037, December 2022., 2022 Large mammalian herbivores inhabiting savanna landscapes are known to shape adjacent freshwater bodies, which are used by a wide variety of species during reproduction. Following a period of intensified poaching in Comoé National Park, Ivory Coast, we quantified major vegetation increase in small temporary ponds, which resulted in significant ...

International Journal of Zoology, Volume 2012, Issue 1, 2012., 2012 Anurans from the rainforest (Okomu National Park) and derived savanna (Agbede) locations in Nigeria were investigated for their role either as intermediate or paratenic hosts of helminth infections. A total of 269 anuran specimens (157 from the Okomu National Park and 112 from Agbede) were examined.
