A systematic map of studies testing the relationship between temperature and an...
Dougherty, Liam R.; Frost, Fay; Maenpaa, Maarit I.; Rowe, Melissah; Cole, Benjamin J.; Vasudeva, Ramakrishnan; Pottier, Patrice; Schultner, EvaExposure to extreme temperatures can negatively affect animal reproduction, by disrupting the ability of individuals to produce any offspring (fertility), or the number of offspring produced by fertile individuals (fecundity). This has important ecological consequences, because reproduction is the ultimate measure of population fitness: a reduction in reproductive output lowers the population growth rate and in...
Systematic approaches to assessing high-temperature limits to fertility in animals
Bretman, Amanda; Fricke, Claudia; Baur, Julian; Berger, David; Breedveld, Merel C; Dierick, Diego; Canal Domenech, Berta; Drobniak, Szymon MCritical thermal limits (CTLs) gauge the physiological impact of temperature on survival or critical biological function, aiding predictions of species range shifts and climatic resilience. Two recent Drosophila species studies, using similar approaches to determine temperatures that induce sterility (thermal fertility limits [TFLs]), reveal that TFLs are often lower than CTLs and that TFLs better predict both ...
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...
International scientists formulate a roadmap for insect conservation and recovery
Harvey, Jeffrey A.; Heinen, Robin; Armbrecht, Inge; Basset, Yves; Baxter-Gilbert, James H.; Bezemer, T. Martijn; Böhm, Monika; Bommarco, RiccardoA growing number of studies are providing evidence that a suite of anthropogenic stressors — habitat loss and fragmentation, pollution, invasive species, climate change and overharvesting — are seriously reducing insect and other invertebrate abundance, diversity and biomass across the biosphere. These declines affect all functional groups: herbivores, detritivores, parasitoids, predators and pollinators. Insec...
