Locomotor, ecological and phylogenetic drivers of skeletal proportions in frogs. [PDF]
J Anat, 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 ...

La Terre et La Vie, Revue d'Histoire naturelle, 1978 The populations of two frogs, Ptychadena maccarthyensis and P. oxyrhynchus, were studied over a four-year period in the Lamto savanna (Ivory Coast), where the climate is characterized by a dry season lasting from December to February, and a rainy season from March to November. P. oxyrhynchus breeds from February to May, while P.

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 ...
