- Abstract
- Understanding the influence of surrounding landscape structure on local habitat quality is necessary to
complement the modelling of empirical relationships between habitat quality and species distribution
patterns. Traditional models explain patterns of bi
odiversity as a function of 'habitat amount in the
landscape', irrespective of spatially
-
explicit variation in habitat fragmentation or habitat quality, implicitly
ignoring the interdependence between spatial components of land
-
use change. The contrasting
hypothesis
-
that local habitat units are not interchangeable because their habitat attributes are dependent on
variation in surrounding habitat structure at both patch and landscape levels
-
was tested using a
hierarchical causal modelling approach
. S
uch
models are observation
-
intensive, so we generated fine
-
grained measures of habitat patch internal heterogeneities (proxies for habitat quality) from very high
resolution Earth Observation images over multiple spatial extents. The results demonstrate the ca
usal
dependence of local habitat quality on surrounding patch and landscape context, and indicate that the
influence of landscape pattern on habitat structure can be mediated by the cross
-
level dependencies
between landscape and patch attributes. From the
spatial context dependence of habitat quality, we
conclude that a substantial degree of
interdependence among habitat effects
is likely to be the norm
in
determining the
ecological consequences of habitat fragmentation. (literal)
