Temporal variation in habitat quality shapes the distribution-abundance relationship in waterbirds at landscape scale
Original language description
The distribution-abundance relationship (DAR) is a well-established macroecological pattern, where more locally abundant species are also more widespread across landscapes. However, it is not clear whether this relationship is temporally invariant, or how destabilization may manifest. Here, we examine the DAR at the landscape level in a unique but overlooked model system, that is, a waterbird assemblage inhabiting fishponds within the Tř eboň sko Basin Biosphere Reserve, Czechia. Using 12 years of biannual census data across 134 intensively managed fishponds, collected in May and July, we describe variation in the slope of the DAR, expressed as the association between bird density and fishpond occupancy. We then tested for the role of environmental parameters and bird traits in determining the relationship's shape, utilizing general multivariate regression and a model-averaging technique. Overall, we corroborated an expected positive DAR for waterbirds, and we present, for the first time, a consistent seasonal weakening of the interspecific DAR. We posit that this decline in the relationship's slope is a result of the deterioration and homogenization of habitat quality later in the summer, which resulted in a large deficit of suitable fishponds as populations increased.
