Bird species co-occurrence patterns in an Alpine environment supports the stress gradient hypothesis
<p>Understanding the relative contribution of different biotic interactions in shaping species assemblages constitutes a major goal in community ecology and consequently, multiple methods aimed at inferring the nature of these associations have emerged during the last decade. In this framework, the stress-gradient hypothesis (SGH) predicts that prevalent biotic interactions shift from competition to facilitation as abiotic stress increases (and productivity decreases). This hypothesis originally raised by plant ecologists has been barely applied to faunal communities. Here, we take advantage of 20 years of abundance data to investigate pairwise patterns in species co-occurrence in Alpine bird communities inhabiting two contrasting habitat types; forests (high-productivity) and mountain grasslands (low-productivity). We also integrate functional data with presence-absence and quantitative matrices in order to detect the signature of processes driving community assembly and test for limiting similarity. We employed a Bayesian approach, probabilistic pairwise association tests and joint Species Distribution Models; all methods revealed a higher frequency of positive interactions in mountain grasslands in agreement with what the SGH predicts. Both the frequency of positive and negative interactions remained moderately stable over the study period in both habitat types. There was no significant relationship between the degree of co-occurrence of species pairs and their functional distance in either habitat. However, when we only considered those combinations of species whose co-occurrence pattern deviated from that expected at random, we found that co-existing species are functionally more similar than those pairs that show segregated patterns in the forest assemblages. Such a relationship may arise via selective social information use and other processes including microhabitat preferences. Overall, our findings suggest that interspecific competition does not seem to be a major force driving the structure of bird assemblages in this mountain region.</p>

Abiotic factors influence species co‐occurrence patterns of lake fishes
<p>This dataset contains the identity of the lakes used for the analyses performed in the paper: Cordero, R., & Jackson, D. (2021). Abiotic factors influence species co‐occurrence patterns of lake fishes. <i>Journal of Animal Ecology</i>. doi:10.1111/1365-2656.13587".</p> <p>This study analyzed the effect of habitat size (i.e., lake area and depth) on the pattern of co-occurrence of multiple fish species in lakes from two different regions, western and central, in Ontario, Canada.</p> <p>The main results of this study were that area and depth showed a significant influence across all the species co-occurrence patterns, in both regions. However, when analyzing groups of species involved in biotic interactions like predator-prey or species sharing similar habitat requirements, we found significant results only for lake area in the central region, which suggests a context-dependency on factors linked with region.</p> <p>Our results demonstrate the effect of environmental variables on species co-occurrence patterns, but the divergent results obtained between geographic regions suggest that such patterns are context-dependent. This study emphasizes the importance of considering abiotic factors in null models of species co-occurrence to obtain reliable and detailed information about the association patterns between species.</p>
