Red wood ants (RWA) of the Formica rufa group are ecosystem engineers and important species in boreal temperate forests. However, permanent temporal loss forest habitats is a serious threat to their existence likely increase with climate change. Due current losing species, quick actions needed. Reported here biogeography, relative abundance habitat preferences five RWA Finland based on citizen ...

This study aimed to evaluate the effect of herbal and immunomodulatory die-tary supplements their combinations on growth performance, slaughter traits meat quality in male broiler chickens. A total 210 one-day-old Ross 308 chickens were randomly distributed after weighing 7 groups (3 replicates each, n=10 chickens). Broilers reared deep litter until 42 days age divided as follows: Group I – con...

fifteen yarrow populations from different species achillea millefolium l., a. biebersteinii l. and a. nobilis, from different geographical areas of iran were studied using 24 morphological traits and peroxidase profiles. comparison of mean values of different phenotypic traits show a. millefolium and a. biebersteinii l. had higher plant height and crown diameter; however, a. nobilis had higher ...

This paper deals with the problem of entry deterrence in two different ways. First, we analyze conditions under which entry prevention is the best strategy for an incumbent firm, and second, we link entry prevention with another important field of industrial organization, the analysis of reasonable conjectures. That entry prevention may be of interest for incumbent firms has been studied by Osb...

In the course of our ongoing screening of plants of the family Asteraceae for antiprotozoal activity, a CH2Cl2-extract from the flowering aerial parts of Achillea ptarmica L. (sneezewort yarrow) was found to be active in vitro against Trypanosoma brucei rhodesiense (IC50 = 0.67 µg/mL) and Plasmodium falciparum (IC50 = 6.6 μg/mL). Bioassay guided fractionation led to the isolation and identifica...

Electrophoretic karyotypes of 15 type strains of the taxa in the Candida guilliermondii complex including Candida fukuyamaensis Nakase et al. and Candida xestobii Yarrow et S. A. Meyer were comparatively analysed by using the CHEF (contour-clamped homogeneous electric field) method of PFGE. Eighteen strains (isolated from various natural sources in China) which were originally identified as C. ...

Body size in animals is affected by both genes and the environment (e.g., the amount of food resources). In ants, body size is related to several traits in an individual's physiology and life history. For example, a large queen may increase offspring production, thus increasing her overall fitness. In this study, whether sub-optimal environmental conditions affect the body size of queens of the...

A 2-year field study on the effect of different light environments, obtained by using cladding materials (polyethylene films and shade net) able to cut off specific regions of the photosynthetically active radiation and ultraviolet wavebands, on the growth and phenylpropanoids content of Achillea collina grown in the Alps was conducted. Overall the plant growth was strongly enhanced in the seco...

Direct seeding is a common large-scale restoration practice for revegetating arid and semi-arid lands, but success can be limited by moisture and temperature. Seed coating technologies that use biochar may have the potential to overcome moisture and temperature limitations on native plant germination and growth. Biochar is a popular agronomic tool for improving soil properties, such as water av...
