Abstract:

Anthropogenic disturbance regimes in areas that were once large continuous habitats have been major drivers of habitat fragmentation and loss which in turn form the largest worldwide threat to biodiversity. Studies suggest that functional trait based approaches provide better understanding of fragmentation effects on ecological processes in human- modified landscapes. However, research on these thematic areas is limited in many tropical regions, such as Ethiopia. In the second chapter of this thesis, I evaluated sensitivity of bird communities and functional groups to fragmentation processes i

Abstract:

Although protected areas have been used as principal conservation tools, most of them are suffering from human-induced threats. Consequently, a good understanding of such human-driven threats on biodiversity and identifying early warning systems for habitat change in protected areas is necessary for effective conservation of natural resources. To examine the impact of human disturbance on avifaunal assemblages and to assess the potential application of birds as bioindicators of forest health monitoring in the Afromontane forest of the Bale Mountains of Ethiopia, I recorded birds and habitat va

Abstract:

Worldwide degradation and conversion of tropical forests affects many species and their provided ecosystem services. Among them are birds, responsible for pollination, seed dispersal, pest control and scavenging. This study, conducted in southwest Ethiopia, compares species composition and bird functional diversity between forest and homegardens close to and far from forest, both in terms of species numbers and bird abundances. Point counts and mist netting were used to obtain data. While the former method detected more species, abundance data from the latter revealed patterns not observed by

Abstract:

Within the steppe-like western slope of the Peruvian Andes forest patches (dry cloud forests) occur from Ecuador to 13°S. Eight localities were studied between Huamba (4°41'S) and Zárate (11°55'S). A total of 145 bird species or 152 taxa (species and well marked subspecies) were recorded. The general distribution of the taxa supports the formerly discussed hypothesis that the majority of species arrived and colonised the western slopes from the north, but also suggests that eastern elements arrived to the western slopes south of the Porculla Pass (5°51'S), that some taxa evolved on the western

Densities of shrubs, saplings, trees, and snags, canopy and ground cover, and foliage volume were the structural variables most influenced by thinning. Populations of shrub/understory birds were higher in thinned stands than unthinned stands. Canopy-dwelling species showed variable population responses to thinning.

Abstract:

Prolific oak regeneration occurred over past centuries from anthropogenic cutting, grazing, and fire, and has declined over the past century due to decreased disturbance. Mesophication within closed-canopy forests of the eastern deciduous region has resulted. Oaks are a keystone species and provide abundant resources for forest wildlife; the ability of late-successional tree species to provide similar resources is relatively understudied. To determine the importance of oak-hickory stands for forest birds, we examined two habitat-selection hypotheses that influence avian abundance and distribut

However, brown creepers (Certhia americana) and hermit thrushes (Cattarus guttatus) were low in abundance or absent in 2 of the minimum stands, yet were common in all other stands. Both species preferred cool, moist microenvironments for nesting and/or foraging; conditions that appeared lacking in the more xeric

Abstract:

The widespread threat of species extinctions caused by the destruction and degradation of tropical primary forest (PF) could potentially be mitigated by the expansion of regenerating secondary forest (SF). However, the conservation value of SF remains controversial, and is dependent on many site- and landscape-scale factors, such as habitat age and isolation. The aim of this thesis was to assess the role that SF can play in conserving forest bird communities in central Panama. We study a chronosequence of SF aged 20 – 120-years-old, with sites either isolated from or connected to extensive PF.

Globally, forest birds are under pressure, from agriculture and urban development fragmenting the landscape.

Furthermore, prescribed burning is applied to the landscape in attempts to not only ameliorate the impacts from bushfire, but as part of a ‘pyrodiversity begets biodiversity’ protocol.

Abstract:

The forest avian community of the Ray Roberts Greenbelt (Denton Co., Texas) was characterized for two years using point count station sampling, from fall 1998 to summer 2000. Richness data for both breeding seasons were correlated with two-spatial metrics: width of the riparian forest and distance to the nearest edge. There were significant correlations between forest interior species richness and both spatial metrics, for both breeding seasons. Based on these data, a minimum riparian forest width threshold of 400-meters is suggested to provide habitat for forest interior species, which have l
