- describing the RANGE of effective spatial scales of birds and butterflies individually, and explaining the probable reasons leading to difference in Ch.3.
- focusing on the common spatial scale, i.e. the suitable scale, which describes comprehensive biodiversity in Ch.4. The suitable scale should be included in effective scales.
This idea is based on my abstract.
The suitable spatial scale(s) is
very important to conduct comprehensive rural landscape research and planning
projects for biodiversity. Therefore, this study aims to use cross-species
biodiversity to define the explanatory power of different spatial scales, and
discuss the effect at the suitable scale(s).
Since both birds and butterflies
are representative to describe rural biodiversity, this study uses
cross-species birds and butterflies as indicator groups of species to examine
the effect of landscape structure, indicated with landscape structure metrics,
at different spatial scale, which is delimited according to birds and
butterflies life range.
This study finds that the
suitable spatial scales for describing comprehensive biodiversity disagree with
the ones for discussing the effect of the most significant land cover types. In
particular, although the scale with extent 100 m and grain size 10 m seems suitable
to meanwhile give consideration to bird and butterfly, the most critical land
cover type, woodland, has more significant correlation with indicators of biodiversity
at larger extent (i.e. 200 or 250 m). These findings effectively help building
a specific spatial scale system for protecting or improving biodiversity in
rural landscape. Furthermore, this study also provides an approach to solve the
spatial issue in landscape research and planning.
