Neighbouring sites (test and burnt ones) were used differently by species: some of them colonised several sites while others were restricted to a single site over the 4 years. Generalist species, as well as some specialist species, were favoured by this new situation, leading to an increased ...
To fully understand the host plant expansion of host-specialized A. gossypii Glover, we used the following strategies: (i) we investigated the capacity of cotton-specialized clones to expand on a new plant species and used host transfer experiments to verify this ability...
First, disturbed habitats often favor opportunistic/generalist species which happen to be reservoirs for hemorrhagic fever viruses. Second, through a process called the dilution effect, in communities of lowering rodent diversity, more and more virus transmission events (aggressive encounters) occur within...
Further study is required for accurate quantification ofnaturalenemyabundance and activity levels, particularly for nocturnally-active species. It is thus unlikely thatnaturalenemyavoidance played a role here. Indeed, this is what would be expected when a single generalist predator is studied in a hig...
- 《Journal of Insect Physiology》 被引量: 110发表: 2009年 Phytosterol metabolism and absorption in the generalist grasshopper, Schistocerca americana (Orthoptera: Acrididae). A series of experiments, using GLC, RP-HPLC, and GC-MS techniques, were performed to examine the metabolic fate and ...
Strategy of Food Plant Selection in the Siberian Northern Pika, Ochotona hyperborea The rock-dwelling pikas of Asia and North America are suitable model species for studying foraging strategies of small generalist herbivores, because they ... J Gliwicz,S Pagacz,J Witczuk - 《Arctic Antarctic &...
We have characterized the MHC class I diversity in 116 Panamanian Seba's short-tailed bats (Carollia perspicillata), a widely distributed, generalist, neotropical species. We have detected a remarkable individual and population-level diversity of MHC class I genes, with between seven and 22 alleles...
Measuring the influence of diet variability is especially important for species with substantial ontogenetic variation, such as generalist predators, in which juveniles often target smaller and lower trophic level prey groups than adults23. Similarly, it is important to consider ontogenetic diet shifts fo...
Overall the deinhibition effect size was larger than that of scarification, however with variation according to species identity. The Sechuran fox, a non-specialized frugivore, proved to be a relevant seed disperser, as may be the case of other neotropical mesocarnivores with generalist diets, ...
Varying survey duration (one, two, three or four hours) and then comparing distribution patterns obtained from species occurrence of each survey duration illustrated that different habitat features were identified as relevant to BFW occurrence. We showed that BFW is a habitat generalist, inhabiting ...
