Ecomechanical measures of performance such as bite force may function as an indirect measure of niche. This study proposes that allometric changes in performance may contribute to niche separation, especially in a group where the specific mechanism(s) remains unclear. We surveyed the bite force and morphology of 5 wild caught, sympatric skink species in the Kimberley region of Western Australia. Skinks were collected from trapline fences, weighed, photographed, and maximum bite force was measured with a piezoresistive force sensor. Morphological metrics were derived from photographs of the dorsum. Normalized morphological traits indicate interspecific variability in form, particularly in forelimb length, …

Nineteen species of ptyctimous mites were found in 20 samples collected in Cameroon: 15 samples from the Southwest region, near the ocean, and 5 samples from the Northwest region, inland. Two new species: Euphthiracarus (Pocsia) inaequatus sp. n. and Steganacarus (Rhacaplacarus) alius sp. n. are described and figured. Six species are new to Cameroon. The so far unknown instars of Mesoplophora (Mesoplophora) invisitata Niedbala, 1983: larva, proto-, deuto-, and tritonymph are described. The deutonymph and tritonymph of M. (M.) invisitata are compared with the corresponding stages of the related species. The tritonymph of the species of both subgenera, Mesoplophora and …
