Description
Summary:Disentangling empirically the many processes affecting spatial population synchrony is a challenge in population ecology. Two processes that could have major effects on the spatial synchrony of wild population dynamics are density dependence and variation in environmental conditions like temperature. Understanding these effects is crucial for predicting the effects of climate change on local and regional population dynamics. We quantified the direct contribution of local temperature and density dependence to spatial synchrony in the population dynamics of nine fish species inhabiting the Barents Sea. First, we estimated the degree to which the annual spatial autocorrelations in density are influenced by temperature. Second, we estimated and mapped the local effects of temperature and strength of density dependence on annual changes in density. Finally, we measured the relative effects of temperature and density dependence on the spatial synchrony in changes in density. Temperature influenced the annual ... : Funding provided by: Norges Forskningsråd Crossref Funder Registry ID: http://dx.doi.org/10.13039/501100005416 Award Number: 223257Funding provided by: Norges Forskningsråd Crossref Funder Registry ID: http://dx.doi.org/10.13039/501100005416 Award Number: 244647 ...
