Macrofungal diversity in Yangambi Biosphere reserve and Yoko reserve rainforests of the Democratic Republic of the Congo
Detecting and understanding patterns in the distribution of taxa is a fundamental element in implementing biodiversity conservation. Regarding fungi, understanding how functional diversity varies with forest types helps to define their niche and allows predicting the impact of forest degradation on communities of macrofungi. It also allows better understanding of the way in which they realize their ecological function...

Moderate communitarianism is different: A Response to J. O. Famakinwa and B. Matolino
Moderate communitarianism is a thesis introduced into African philosophical literature by the Akan philosopher Kwame Gyekye. He suggests that this thesis better accounts for the Akan and, to some extent, African social set-up than what he calls radical communitarianism (a thesis which he attributes especially to John Mbiti and Ifeanyi Menkiti). However, Gyekye is criticised by J. O. Famakinwa and B. Matolino for...
