ScLi5- Identify the purpоse оf intrоduction in scientific pаpers This is the introduction of Hаbitаt fragmentation reduces nest survival in an Afrotropical bird community in a biodiversity hotspot. The authors of this paper wanted to determine if habitat fragmentation had an effect on nest survival in African birds. "1. Reduced nest survivorship, due to elevated rates of nest predation, has long been hypothesized as an important contributory factor to population declines and local extinctions of birds in fragmented tropical landscapes (1, 2). Habitat fragmentation results in a reduction in area, an increase in remnant isolation, the creation of edge, and an alteration in the habitat structure of the remnants, all of which may contribute either directly or indirectly to changes in avian nest survival (3–6). Given that nearly two thirds of all bird species are endemic to the tropics (7, 8) and that moist tropical forests are being lost worldwide at a rate of 0.52% annually (9), understanding the impact of habitat fragmentation on the demography of tropical birds is clearly important for avian conservation. 2. However, because of the difficulty of finding large numbers of well-hidden nests in tropical forests (10, 11), rigorously assessing the impact of habitat fragmentation on avian nest survivorship has been challenging. Previous studies comparing avian nest survivorship between fragmented and intact forest in the tropics have either used artificial nests and eggs (12, 13), which unfortunately often poorly mimic the fate of real nests and eggs (14–16); or if real nests have been found, have lumped species together in the analysis because of small sample sizes (17), which can be misleading because nest survivorship can vary locally among tropical bird species (18–21). Similarly, the few studies in the tropics that have examined edge effects on nest survival using real nests and eggs have been either single-species studies (22) or have pooled nests across species (17). Thus, our understanding of the influence of landscape structure and nest location on avian nest survival across tropical bird communities is quite limited."
