Due to legislative protection, many species, including large carnivores, are currently recolonizing Europe. To address the impending human-wildlife conflicts in advance, predictive habitat models can be used to determine potentially suitable habitat and areas likely to be recolonized. As field data are often limited, quantitative rule based models or the extrapolation of results from other stud...

Reliable analyses can help wildlife managers make good decisions, which are particularly critical for controversial decisions such as wolf (Canis lupus) harvest. Creel and Rotella (2010) recently predicted substantial population declines in Montana wolf populations due to harvest, in contrast to predictions made by Montana Fish, Wildlife and Parks (MFWP). We replicated their analyses considerin...

The recent recolonization of Central Europe by the European gray wolf (Canis lupus) provides an opportunity to study the dynamics of parasite transmission for cases when a definitive host returns after a phase of local extinction. We investigated whether a newly established wolf population increased the prevalence of those parasites in ungulate intermediate hosts representing wolf prey, whether...

The grey wolf (Canis lupus) is an iconic large carnivore that has increasingly been recognized as an apex predator with intrinsic value and a keystone species. However, wolves have also long represented a primary source of human-carnivore conflict, which has led to long-term persecution of wolves, resulting in a significant decrease in their numbers, genetic diversity and gene flow between popu...

Abstract Conservation biological control could be an alternative to insecticides for the management of aphid Myzus persicae (Sulzer). To develop sustainable strategies M. in peach orchards Mediterranean, a 2-yr field experiment was conducted identify key predators aphid; determine whether proximity insectary plants boost natural enemies comparison resident vegetation; and selected enhance enemy...

Wolf restoration has become a widely accepted conservation and management practice throughout North America and Europe, though the ecosystem effects of returning top carnivores remain both scientific and societal controversies. Mathematical models predicting and describing wolf-ungulate interactions are typically limited to the wolves' primary prey, with the potential for prey switching in wolf...

We investigate the relation between the equivalent width of He ii emission lines and the monochromatic continuum luminosity at the line wavelength in the spectra of Wolf-Rayet stars. Model stellar atmospheres and spectra are used to show that the equivalent width inversely correlates with the monochromatic continuum luminosity. We find the effect in Wolf-Rayet star models over a large range of ...

Due to the detrimental side-effects of synthetic pesticides, use nonchemical strategies in management insect pests is necessary. In present study, susceptibility fourteen eggplant cultivars green peach aphid (M. persicae) were investigated. According preliminary screening tests, ‘Long-Green’, ‘Ravaya’ and ‘Red-Round’ as relatively resistant, ‘White-Casper’ ‘Pearl-Round’ susceptible recognized. ...

Plant viruses, and aphids as their vectors, are limiting factors in sugar beet production. Viral plant diseases currently impossible to treat but knowing the flight patterns of can help reducing number potential virus vectors. Monitoring aphid activities fields was done using yellow water traps from April end November. During two years investigation, a total 5514 specimens 75 different taxa wer...

This work includes, identification eight species of Aphids (Homoptera: Aphididae) which collected from the leaves different plants in many localities Erbil governorate Kurdistan region-Iraq period May till July 2022, these are: Chaitophorus salijaponicus, Aphis fabae, Macrosiphum rosae, Capitophorus carduinus, Myzus persicae, ruborum, punca, and gossypii. The mitochondrial cytochrome C Oxidase ...
