Ecologically and evolutionarily important SNPs identified in natural populations.
Evolution by natural selection acts on natural populations amidst migration, gene-by-environmental interactions, constraints, and tradeoffs, which affect the rate and frequency of adaptive change. We asked how many and how rapidly loci change in populations subject to severe, recent environmental changes. To address these questions, we used genomic approaches to identify randomly selected singl...
متن کاملGenetic and epigenetic variation in a cosmopolitan grass Poa annua from Antarctic and Polish populations
Poa annua L. is the only non−native vascular plant that was successfully estab− lished in the maritime Antarctic. This project aimed to determine the amount of genetic and epigenetic variation within and between two populations of P. annua, one from South Shet− land Is. (Antarctic) and the other one from Central Europe. We applied two AFLP marker systems, using endonucleases that recognised the...
متن کاملPotential selection in native grass populations by exotic invasion.
Ecological impacts of invasive plant species are well documented, but the genetic response of native species to invasive dominance has been often overlooked. Invasive plants can drastically alter site conditions where they reach dominance, potentially exerting novel selective pressures on persistent native plant populations. Do native plant populations in old exotic invasions show evidence of s...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولNative herbivores and plant facilitation mediate the performance and distribution of an invasive exotic grass
1. Exotic plant species have become increasingly prominent features of ecological landscapes throughout the world, and their interactionswith native and exotic taxa in these novel environments may play critical roles inmediating the dynamics of such invasions. 2. Here, we summarize results from comparative and experimental studies that explore the effects of two factors – herbivory and facilita...
