Habitat effects on behaviour and ecology of forest generalist birds

点击翻译按钮获取中文摘要

Human land use has the potential to impact the structure of habitats. Following logging, regeneration of forests occurs either through natural re-growth or intentional planting, yet these young forests often lack many of the resources found in mature forests. Such alteration of the landscape may provide relatively poor habitat to birds and other species that settle here. Further, regenerating forests often differ considerably in tree species from those originally logged. These 'mosaics' of habitat types often abut one another, creating abrupt zones of contact between species that typically occupy different forests. This can lead to cross-species matings (hybridization) between normally habitat-isolated species. Despite this potential impact, we often overlook how human land use affects the quality of the habitat and the induced interactions this can create among generalist bird species.
