Ecological predictors of the endangered Spirlin (Alburnoides bipunctatus)
Original language description
The distribution of aquatic species results from the complex interplay of biotic and abiotic variables, anthropogenic impacts, and scale effects. Using the results of a large-scale fish monitoring survey, we fitted a spatially-explicit Bayesian model to compare a series of a priori models for predicting the occurrence of the Spirlin (Alburnoides bipunctatus), a small freshwater cyprinid fish of conservation concern. The best-fitting model identified an important effect of river basin, flow disruption, and the number of other fish taxa as predictors. Among major river basins, sampling locations in the Vistula Basin were the most likely to support Spirlin, a possible outcome of postglacial colonisation events and less anthropogenic habitat change. The negative association between flow disruption, comprising engineering schemes for flow regulation, river fragmentation caused by obstacles such as dams, and changes to flow due to water abstraction, reflected the Spirlin's requirements for relatively pristine ecological conditions, including flow heterogeneity and access to coarse substrates for spawning. Similarly, a positive association between the occurrence of Spirlin and fish species richness demonstrates the association of this species with aquatic habitats of high ecological integrity. These findings implicate river fragmentation and changes to flow regime as predictors of river habitat integrity and lend support to the proposition that the Spirlin can function as an indicator species for the monitoring and maintenance of the ecological health of river habitats across Europe. Model predictions also point towards the removal of measures that disrupt river flow, combined with restoration of a coarse benthic substrate, as approaches to mitigate declines in populations of Spirlin across Europe.
