Inter-seasonal and inter-habitat variations in the diet of the African fire skink, Lygosoma fernandi, from southern Nigeria
No full textThe inter-habitat and inter-seasonal variations in the taxonomic diet composition of the African fire skink, Lygosoma fernandi, one of the largest Scincidae of the Afrotropical regions, were studied by analysis of excrements collected from live individuals that were captured in some areas of the Niger Delta region, southern Nigeria. 22 prey types, mostly arthropods, were found in the diet of this species, with significant differences in prey composition between seasons. Isopoda and Coleoptera dominated in the dietary samples, with very few prey types exclusive of one habitat type and/or season (e. g. Formicidae in dry forest in both seasons and lizards in swamp forest in wet season). Overall, no difference between forest types and seasons was found as for diversity and evenness indices except for that prey diversity was higher in feces collected in the dry forest in dry season, whereas dominance and evenness did not show any significant variation across forest types

Aspects of the ecology of the tortoise Kinixys nogueyi (Lataste, 1886) in Togo and Nigeria (West Africa)
No full textIn this study, the sex ratio, habitat use, and diet of free-ranging Kinixys nogueyi are examined. Sex ratio and habitat use were examined in Togo and Nigeria (West Africa), and food habits only in Nigeria. Sex ratios were equal in both populations. Tortoises had clear habitat preferences in both countries, and the Nigerian population exhibited seasonal but not inter-sexual differences in habitat selection. The present study demonstrated that this species inhabits not only Guinea savannahs and relatively wet savannahs, as already reported in the literature, but also rainforest patches and hilly forests, especially in Togo. Food remains in the feces of Nigerian specimens belonged to plants and fungi as well as to animals, with inter-seasonal but not inter-sexual differences in dietary composition. In particular, there was a significant shift from a diet based mostly on animal food in the dry season towards a mainly vegetarian diet in the wet season

Who does bask longer? A comparison between elapid and viperid snakes in the field and in experimental conditions
No full textTemperature profoundly influences the biology of ectotherm organisms, for example reptiles, which mostly regulate their body temperature behaviorally by shuttling between heat sources and sinks. The thermal quality of the environment directly affects the amount of time that a reptile takes to keep the body temperature within the optimal range. The foraging strategy of reptiles is often correlated to the thermoregulatory strategies. Depending on their foraging strategy, carnivorous reptiles can be high-energy consumers (active foragers) or low-energy consumers (ambush foragers). Our study allowed to get insights into basking versus non-basking behaviors of (i) snakes belonging to two different families (eight viperids and four elapids) with contrasted life-styles by either field or captive observations, (ii) free-ranging snakes (n = 3245) inhabiting contrasted habitats (forest versus savannah), and (iii) captive snakes (n = 4) outside the feeding activity and during digestion phase. We observed a tendency to spend more time in thermoregulation in the viperids than in the elapids and this pattern were consistent between field and experimental observations. We suggest that the higher basking activity of viperids is correlated to their predominantly nocturnal and ambush habits compared to the diurnal and active-foraging habits of the elapids. We also observed an effect of the thermal environmental quality with the savannah species tending to bask less than forest species. As for postprandial termophily, viperids showed a longer postprandial basking time than elapids even if all the snakes in the captivity sample were fed identically in terms of prey type and relative prey mass. Conservation insights related to the observed pattern are also provided
