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...

Maruyama, Pietro Kiyoshi; Vizentin-Bugoni, Jeferson; Sonne, Jesper; Martín González, Ana M.; Schleuning, Matthias; Araujo, Andréa Cardoso deAim: To investigate the role of alien plants in mutualistic plant-hummingbird networks, assessing the importance of species traits, floral abundance and insularity on alien plant integration. Location: Mainland and insular Americas. Methods: We used species-level network indices to assess the role of alien plants in 21 quantitative plant-hummingbird networks where alien plants occur. We then evaluated whether p...
High proportion of smaller ranged hummingbird species coincides with ecological...
Sonne, Jesper; Martín González, Ana M.; Maruyama, Pietro Kiyoshi; Sandel, Brody S.; Vizentin-Bugoni, Jeferson; Schleuning, Matthias; Abrahamczyk, StefanEcological communities that experience stable climate conditions have been speculated to preserve more specialized interspecific associations and have higher proportions of smaller ranged species (SRS). Thus, areas with disproportionally large numbers of SRS are expected to coincide geographically with a high degree of community-level ecological specialization, but this suggestion remains poorly supported with ...
On the Hyperbox – Hyperplane Intersection Problem
Lara, Carlos; Flores, Juan J.; Calderon, FelixFinding the intersection between a hyperbox and a hyperplane can be computationally expensive specially for high dimensional problems. Naive algorithms have an exponential complexity. A border node is a node (in the graph induced by the hyperbox) at or next to the intersection of the hyperbox and the hyperplane. The algorithm proposed in this paper implements a systematic way to efficiently generate border node...
