Global urban environmental change drives adaptation in white clover
Santangelo, James S.; Ness, Rob W.; Cohan, Beata; Fitzpatrick, Connor R.; Innes, Simon G.; Koch, Sophie; Miles, Lindsay S.; Munim, SamreenMade available in DSpace on 2022-04-28T19:52:06Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-03-18; Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also...
Global urban environmental change drives adaptation in white clover
Santangelo, James S.; Ness, Rob W.; Cohan, Beata; Fitzpatrick, Connor R.; Innes, Simon G.; Koch, Sophie; Miles, Lindsay S.; Munim, SamreenUrbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6,169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defence that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines i...
Climate mediates the effects of disturbance on ant assemblage structure
Gibb, Heloise; Sanders, Nathan J.; Dunn, Robert R.; Watson, Simon J.; Photakis, Manoli; Abril, Sílvia; Andersen, Alan N.; Angulo, Elena; Armbrecht, IngeMany studies have focused on the impacts of climate change on biological assemblages, yet little is known about howclimate interacts with other major anthropogenic influences on biodiversity, such as habitat disturbance. Using a unique global database of 1128 local ant assemblages, we examined whether climate mediates the effects of habitat disturbance on assemblage structure at a global scale. Species richness...
Drivers of future alien species impacts: an expert‐based assessment
Essl, Franz; Lenzner, Bernd; Bacher, Sven; Bailey, Sarah; Capinha, César; Daehler, Curtis; Dullinger, Stefan; Genovesi, Piero; Hui, CangUnderstanding the likely future impacts of biological invasions is crucial yet highly challenging given the multiple relevant environmental, socio-economic and societal contexts and drivers. In the absence of quantitative models, methods based on expert knowledge are the best option for assessing future invasion trajectories. Here, we present an expert assessment of the drivers of potential alien species impact...
A global database of ant species abundances
Gibb, Heloise; Dunn, Rob R.; Sanders, Nathan J.; Grossman, Blair F.; Photakis, Manoli; Silva, Rogerio R.Quais forças estruturam as assembleias ecológicas? Uma limitação importante para insights gerais sobre estrutura de assemblage é a disponibilidade de dados que são coletados em um pequeno espaço grãos (assembléias locais) e uma grande extensão espacial (cobertura global). Aqui, apresentamos publicado e dados não publicados de 51, 388 registros de abundância e ocorrência de formigas de mais de 2.693 espécies e 7...
Coefficient shifts in geographical ecology: an empirical evaluation of spatial ...
Bini, L. Mauricio; Diniz-Filho, J. Alexandre F.; Rangel, Thiago F. L. V. B.; Akre, Thomas S. B.; Albaladejo, Rafael G.; Albuquerque, Fabio S.A major focus of geographical ecology and macro ecology is to understand the causes of spatially structured ecological patterns. However, achieving this understanding can be complicated when using multiple regressions, because the relative importance of explanatory variables, as measured by regression coefficients, can shift depending on whether spatially explicit or non-spatial modelling is used. However, the ...
