| Tóm tắt: | Insects present conservationists with a very different set of challenges in
comparison with more popular groups such as vertebrate animals and vascular
plants. These are a consequence of several aspects of their life histories
that make them especially vulnerable to the types of environmental changes
currently being experienced across many temperate regions (McLean, 1990;
Kirby, 1992; UK Biodiversity Group, 1999). Many insects have highly specialized
habitat (and often microhabitat) requirements that are further complicated by
the fact that the discrete stages in the life cycle often require radically different
resources. Most insects have comparatively short life cycles (often annual
or more frequent) with no dormant stage in which they can escape adverse
conditions, so that these habitat requirements have to be met without interruption.
Finally, many species are incapable of dispersing more than trivial
distances, or are behaviourally reluctant to do so, resulting in their complex
habitat requirements having to be met within relatively small areas and an
increased sensitivity to habitat fragmentation. Thus, maintenance of habitat
quality, continuity, heterogeneity and connectedness are recurrent themes in
insect conservation biology. |
