Land‐use intensity affects the potential for apparent competition within and between habitats

چکیده
Arthropod communities dwelling in adjacent habitats are able to impact one another via shared natural enemies. In agricultural landscapes, drastic differences resource availability between crop and non-crop cause variation insect herbivore densities over short distances, potentially driving inter-habitat effects. Moreover, the composition of landscape which embedded likely affects realised attack rates from enemies impacts on local arthropod community structure. Here, we examine indirect effects species within habitat types by calculating potential for apparent competition multiple populations. Firstly, aim determine how disparities strength occurring habitats, secondly upon these effects, finally couch observations reality investigating link rates. We used DNA metabarcoding characterise host–parasitoid interactions two (with divergent nutrient inputs) at 11 locations with variable an agroecosystem context. then interaction networks estimate each host pair compare expected versus across system. Shared were found structure boundaries. The size this effect was related such that high input exerted a stronger effect. overall declined increasing land-use intensity surrounding exhibited discernible species. Thus, our results suggest proportion perennial agroecosystems could increase prevalence as among communities, leading enhanced population regulation increased like parasitoid wasps.

Genetic differentiation within and between two habitats.
We investigate the usefulness of analyses of population differentiation between different ecological types, such as host races of parasites or sources and sink habitats. To that aim, we formulate a model of population structure involving two classes of subpopulations found in sympatry. Extensions of previous results for Wright's F-statistics in island and isolation-by-distance models of dispers...

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

Although the evolutionary consequences of within-host competition among pathogens have been examined extensively, there exists a critical gap in our understanding of factors determining the prevalence of multiple infections. Here we examine the effects of relatedness among strains of the anther-smut pathogen Microbotryum violaceum on the probability of multiple infection in its host, Silene lat...

from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...
