Relationship between Survival Rate of Avian Artificial Nests and Forest Vegetation Structure Along a Tropical Altitudinal Gradient on Mount Cameroon

Popis výsledku v původním jazyce

Nest predation is assumed to be an important factor driving avian life histories. Altitudinal gradients offer valuable study systems to investigate how avian nest predation risk varies between bird populations. In this study, a hypothesis postulating anincrease in avian nest survival rate with elevation as a result of decreasing predation pressure was experimentally tested along an altitudinal gradient (300-2250 m) in West-Central Africa. Three types of artificial nests (cup-shrub, cup-ground and bare-ground) were used along the altitudinal gradient. Overall, elevation had no effect on the daily survival rate (DSR) of the artificial nests. However, there was a significant elevation-nest type interaction. Daily survival rate for cup-shrub nests decreased significantly with elevation, but for cup-ground and bareground nests, elevation had no significant effect. We tested the effects of the same vegetation parameters (tree density, herb and shrub layer coverage, and canopy openness) on t
