Habitat effects on behaviour and ecology of forest generalist birds

人类土地利用有可能影响生境的结构。 伐木后，森林的再生要么通过自然再生长，要么通过有意种植，但这些年轻的森林往往缺乏成熟森林中的许多资源。 这种景观的改变可能会为在这里定居的鸟类和其他物种提供相对较差的栖息地。 此外，再生森林的树种往往与原来砍伐的树种有很大不同。 这些栖息地类型的“马赛克”通常彼此邻接，在通常占据不同森林的物种之间形成突然的接触区。 这可能导致通常栖息地隔离物种之间的跨物种交配（杂交）。 尽管有这种潜在的影响，我们往往忽视了人类土地利用如何影响栖息地的质量和诱导的相互作用，这可以创造通才鸟类。

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.
