: Species range expansion constrains the ecological niches of resident butterflies
نویسندگان
چکیده
• Changes in community composition resulting from climate change entail modifications of biotic interactions and reshape local species distributions. Such changes are currently occurring in nettle-feeding butterflies in Sweden where Araschnia levana has recently expanded its range northward and is now likely to interact with the resident species (Aglais urticae and Aglais io). Butterfly occurrence data collected over years and across regions enabled us to investigate how a recent range expansion of A. levana may have a↵ected the environmental niche of

متن کاملEcological Niche Transferability Using Invasive Species as a Case Study
Species distribution modeling is widely applied to predict invasive species distributions and species range shifts under climate change. Accurate predictions depend upon meeting the assumption that ecological niches are conserved, i.e., spatially or temporally transferable. Here we present a multi-taxon comparative analysis of niche conservatism using biological invasion events well documented ...
متن کاملDivergence and ontogenetic coupling of larval behaviour and thermal reaction norms in three closely related butterflies.
Genetic trade-offs such as between generalist-specialist strategies can be masked by changes in compensatory processes involving energy allocation and acquisition which regulation depends on the state of the individual and its ecological surroundings. Failure to account for such state dependence may thus lead to misconceptions about the trade-off structure and nature of constraints governing re...
متن کاملInvestigation of rain fed perennial range plant instead of annual species for ecological control of soil erosion
One of the most important waysto decrease surface evorsion and increase forgie production is cultration of When we cultivate corns and we have not any good yields we can change the corn species with perennial range species. It causes to decrease surface erosion and increase forage production. The goal of this study is assessing of unsuccessful reasons in forage rain fed cultivation of Onobrychi...
متن کاملComparing range evolution in two western Plethodon salamanders: glacial refugia, competition, ecological niches, and spatial sorting
Methods We used genetic, environmental and morphological data to test hypotheses that explain this range difference. Genetic data were used to explore range expansion dynamics and population structure. Species distributional models were used to compare current niches to mid-Holocene and Pleistocene distributions. Morphological data were used to assess phenotypic differences between the species ...
