An experimentally introduced population of Brassica rapa (Brassicaceae), 1. Phenotypic selection over three years following colonization of a novel environment / Michael Sekor in Plant Ecology and Evolution, vol. 151, n°2 (Année 2018)
[article]
Titre : An experimentally introduced population of Brassica rapa (Brassicaceae), 1. Phenotypic selection over three years following colonization of a novel environment Type de document : Livre Auteurs : Michael Sekor, Auteur ; Steven Franks, Auteur Année de publication : 2018 Article en page(s) : pp. 209-218 Langues : Anglais Mots-clés : Natural selection plants phenotypic selection morphology flowering time Brassica rapa ecological genetics introduction d'espèce Aster model Résumé : "The results suggest that selection is dynamic and can fluctuate over time. Thus multi-year assessments of selection are useful for predicting evolutionary responses, particularly in the early stages of colonization of a novel environment."

Rapid evolution of phenotypic traits Type de document : Livre Auteurs : Michael Sekor, Auteur ; Steven Franks, Auteur Année de publication : 2018 Article en page(s) : pp. 293-302 Langues : Anglais Mots-clés : Rapid evolution plants resurrection approach morphology flowering time Brassica rapa experimental introduction introduction d'espèce Résumé : "This study found rapid evolution of several morphological and phenological traits, including smaller plant size and shorter time to flowering, following introduction, confirming that evolution can rapidly occur during the early stages of colonization. Many traits evolved in the opposite direction predicted from phenotypic selection analysis, which suggests that the resurrection approach can reveal unanticipated evolutionary changes and can be very useful for studying contemporary evolution."

Titre : Old concepts, new challenges: adapting landscape-scale conservation to the twenty-first century Type de document : Livre Auteurs : Lynda Donaldson, Auteur ; Robert J. Wilson, Auteur ; Ilya Maclean, Auteur Année de publication : 2017 Article en page(s) : pp. 527–552 Langues : Anglais Mots-clés : beta-diversity insects arthropods plants conservation management trait Résumé : "Landscape-scale approaches to conservation stem largely from the classic ideas of reserve design: encouraging bigger and more sites, enhancing connectivity among sites, and improving habitat quality. Trade-offs are imposed between these four strategies by the limited resources and opportunities available for conservation programmes, including the establishment and management of protected areas, and wildlife-friendly farming and forestry. Although debate regarding trade-offs between the size, number, connectivity and quality of protected areas was prevalent in the 1970–1990s, the implications of the same trade-offs for ongoing conservation responses to threats from accelerating environmental change have rarely been addressed. Here, we reassess the implications of reserve design theory for landscape-scale conservation, and present a blueprint to help practitioners to prioritise among the four strategies. We consider the new perspectives placed on landscape-scale conservation programmes by twenty-first century pressures including climate change, invasive species and the need to marry food security with biodiversity conservation. A framework of the situations under which available theory and evidence recommend that each of the four strategies be prioritized is provided, seeking to increase the clarity required for urgent conservation decision-making."

Titre : The Genus Crypsis (Gramineae) in the United States Type de document : Livre Auteurs : Barry Hammel, Auteur ; John Reeder, Auteur Année de publication : 1979 Article en page(s) : pp. 267-280 Langues : Anglais Mots-clés : graine Flora Taxa Plants Spikelets Lake water chromosome Glume Résumé : "The Old World grass genus, Crypsis, is represented in the United States by three naturalized taxa. Although these are usually treated as specifically distinct in America, European botanists consider two of them to be merely different growth forms of the same species. The few chromosome counts in the literature suggest x = 9 as the basic number. Our studies, including chromosome counts from 44 populations and seed protein analyses from 32 populations, demonstrate that the three taxa differ chemically and represent a polyploid series with a diploid, a tetraploid, and a hexaploid, and a basic chromosome number of x = 8. Each entity seems specifically distinct, and can be recognized by small, but consistent morphological characteristics. Evidence is presented indicating that the correct name for the species listed as C. niliaca in Hitchcock's Manual is Crypsis vaginiflora (Forsk.) Opiz."
