IA Fleming,MR Gross - 《Evolution》 被引量: 1251发表: 1994年 Female competition and its evolutionary consequences in mammals Following Darwin's original insights regarding sexual selection, studies of intrasexual competition have mainly focused on male competition for mates; by c... P Stockley,Jako...
Hybridization data also contradict Andersen's phylogeny in providing support for an endemic African clade that includes representatives of three of Andersen's sections. Here, we present complete mitochondrial 12S rRNA and valine tRNA gene sequences for 20 pteropodids, including representatives of all ...
cities, an evolution attributed to the decline in anthropogenic emissions and the resulting growing importance of background NO2, whereas NO2 lifetime changes also play a minor role. In particular, the Sunday NO2 columns averaged over all U.S. cities are found to increase, relative to the ...
The WSF-Evo dataset is publicly available for download from https://geoservice.dlr.de/web/maps/eoc:wsfevolution. We use proprietary global fluvial and pluvial flood-hazard data with the permission of Fathom Global, who provide the data for academic purposes and can be contacted at https://www...
Turnera sidoides is a complex of distylous perennial rhizomatous herbs that includes five subspecies. Since polyploidy has played a prominent role within this species ( x =7), ongoing studies in T. sidoides are focused on the understanding of the mechanisms involved in the origin and the establi...
Sample populations of 157 Cannabis accessions of diverse geographic origin were surveyed for allozyme variation at 17 gene loci. The frequencies of 52 alleles were subjected to principal components analysis. A scatter plot revealed two major groups of accessions. The sativa gene pool includes fiber/se...
The genus Erebia is known for its cryptic diversity (Sonderegger 2005; Descimon and Mallet 2009) and also includes “geographical replacement species”, i.e. species or lineages that replace each other by their vicariant sibling in parts of their range (Vodă et al. 2015). The taxonomic ...
Our study provides evidence of planet signatures and facilitates a deeper understanding of the star–planet–chemistry connection by providing observational constraints on the mechanisms of planet engulfment, formation and evolution. This is a preview of subscription content, access via your institution ...
To analyze the evolution of these distributions and traits, we derived a molecular phylogeny for representatives of 14 genera, based on sequence variation in the chloroplast-encoded ndhF gene. The lowland subfamily Rapateoideae is paraphyletic and includes the largely montane subfamily Saxofridericio...
Although monsoon possibly drove the evolution of many mammal lineages during the Neogene, no evidence thereof has been provided so far. We examined the evolutionary history of a clade of rodents, the Rhizomyinae, in conjunction with our current knowledge of monsoon fluctuations over time. The ...
