Invasive pest species may strongly affect biotic interactions in agro-ecosystems. The ability of generalist predators to prey on new invasive pests may result in drastic changes in the population dynamics of local pest species owing to predator-mediated indirect interactions among prey. On a short time scale, the nature and strength of such indirect interactions depend largely on preferences be...
در بررسیهای بیواکولوژیک و تعیین فون کنه های انباری کازرون که در سالهای 1372-70 انجام گرفت جمعا" 52 گونه کنه متعلق به 4 راسته و 22 خانواده جمع آوری و شناسایی گردید که در بین آنها هشت خانواده و 43 گونه برای اولین بار از ایران و یک گونه جدید بنام bdellodes kazeruni برای اولین بار از دنیا گزارش می شوند. در بین گونه های جمع آوری شده دو گونه مهم و حائز اهمیت اقتصادی rhizoglyphus robini و r.echinopus ...
A thorough research on the scientific activity of Guglielmo Gasparrini, Giovanni Gussone and Augustin Pyramus De Candolle allowed authors to adress a in several European herbaria looking for type name Senecio pygmaeus DC. The original specimen sent by mentioned protologue is still kept at G-DC designated as lectotype, whilst three other herbarium sheets, preserved NAP-GUSS, PAL PAV respectively...
It has been suggested that recombination may be mutagenic, which, if true, would inflate intraspecies diversity and interspecies silent divergence in regions of high recombination. Here, we test this hypothesis comparing human/orangutan genome-wide non-coding divergence (K) to that in the pseudoautosomal genes which were reported to recombine much more frequently than the rest of the genome. We...

Omnivorous Heteroptera constitute an important component of predatory guilds with high potential for biological control. Understanding the relative effects of plant feeding on the suppression of prey by omnivores could be an important element for improving biological control strategies. In the current paper, the effects of different plant food sources on the predation rate of the omnivorous pre...
The study of comparative energetics offers a valuable way to identify broad ecological principles and assess the functional significance of energetic adaptations during the course of evolution. Yet, the quantification of energetic status for nonhuman primates under natural conditions remains one of the most challenging aspects of comparative energetics research. Here, we report on the developme...
Urbanization is a key global driver in the modification of land use and has been linked to population declines even in widespread and relatively common species. Cities comprise a complex assortment of habitat types yet we know relatively little about the effects of their composition and spatial configuration on species distribution. Although many bat species exploit human resources, the majorit...
