The reliability of a composite biodiversity indicator in predicting bird species richness at different spatial scales

摘要: Abstract Several biodiversity features can be linked to landscape heterogeneity, that, in turn, informative for management and conservation purposes. Usually, the more is complex increases. Biodiversity indicators a useful tool assess status, function of heterogeneity. In this study, we developed indicator, based on Shannon diversity index built from distribution maps protected species. With such an approach, seek evaluate feasibility using combination target species as surrogate assessing status whole bird community. Our approach was spread over multiple spatial scales, determine which most informative. We selected four by European regulation generated presence-absence map modelling. We, therefore, used FRAGSTATS metric calculate overlapped maps, at two scales (500 m 1000 m). Then, relationships with community assessed through generalised least square models, scale 4 ha, 9 ha 25 ha. Results showed that higher rate variability explained indicator 1000 m scale. Indeed, 9 ha. addition, pattern emerged about between richness, worth further research. study demonstrates usefulness assessment become clear only certain scales. they highly predictive community, planning. Moreover, their use optimize monitoring conservation, focusing small number noteworthy
