Small mammal community demography and reproductive seasonality under protection, pastoralism and agriculture in the Serengeti Ecosystem, Tanzania

We examined population demography and reproductive seasonality among small mammals under protection, pastoralism and agriculture in the Serengeti Ecosystem in 2017 and 2018. We trapped small mammals to quantify variation in the proportions of actively breeding individuals, juvenile recruitment and adult sex ratio across land use types and seasons. Breeding peaked in the wet season, reflecting a corresponding underlying...

Sampling techniques for the optimal measurements of macromycetes diversity in the Soudano-Guinean ecozone (West Africa)

Fungi range among the most important organisms in the world thanks to their ecological roles in the ecosystems and their socio-economic importance for human beings. Still, the global fungal species richness is full of uncertainties as evidenced by various estimates. Estimating fungal species richness and diversity is raising many questions related to the sampling effort (in space and time). This study aims to determine...
