Effects of forestry practices on vegetation structure and bird community of Kibale National Park, Uganda
I examined the lingering effects of past timber management practices on the vegetation structure and bird community of Kibale National Park, Uganda. I compared four forest treatments: unlogged native forest (UL), two that were selectively logged at low (LL) and high (HL) intensities in the 1960s, and a conifer plantation (PL). Forest-dependent birds were best represented at UL. LL was similar t...
متن کاملEffect of Vegetation Structure on Bird Vocalizations
In preparing for my presentation, I was recommended several review articles from compilations on bird vocalizations. I based much of my presentation on this particular review. It is a bizarre combination of a little bit of ethology and a good many predictions on how environmental features should influence the evolution of characteristics of bird song such as frequency, amplitude, modulatory emp...

متن کاملNegative Effects of an Introduced Bird Species on Growth and Survival in a Native Bird Community
Exploitative competition is a major determinant of community structure in natural assemblages [1, 2], but, introduced species are rarely competitors that lead to extinction of native species [3, 4]. Here we document strong community-wide competition from the Japanese white-eye (Zosterops japonicus) on native Hawaiian passerine birds. Introduced in 1929 [5], white-eye successfully invaded old-gr...
متن کاملBird community specialization, bird conservation and disturbance: the role of wildfires.
1. Although niche theory predicts that disturbance should favour generalist species, the community-level implications of this pattern have been sparsely analysed. Here, we test the hypothesis that disturbance favours generalist species within communities, analysing effects of wildfires in bird communities in a Mediterranean climate area as a case study. 2. We use bird occurrence data in more th...
