Elliptic problem involving non-local boundary conditions

Noureddine Igbida and Soma Safimba

In this paper, we study existence and uniqueness of a solution for a nonlinear elliptic problem subject to nonlocal boundary condition. Moreover, we prove the equivalence between this kind of problem and nonlinear problem with very large diffusion around the boundary.

Impact of human activities on the reproduction of Hooded Vultures Necrosyrtes monachus in Burkina Faso

Clément Daboné, Ralph Buij, Adama Oueda, Jacques Boko Adjakpa, Wendengoudi Guenda & Peter DM Weesie

During the last decades, the critically endangered Hooded Vulture Necrosyrtes monachus has strongly declined across its African range. Although direct persecution has been suggested as a major cause of this decline, little is known about the impact of humans on reproductive output in West Africa. We studied the impact of human activities on th(...)
