Meadow vole food preferences were examined by means of a serie s of two day trials where pairs of plants were offered. Of the six plants tested, three (white clover, red clover, alfalfa) were found to be highly preferred by the voles, one (red fuscue) was acceptable, and two species (myrtle and crownvetch) were unacceptable. The results suggest that the undesirable groundcovers may be used as a...

continued on page 4 The term allelopathy was first introduced in 1937 and refers to biochemical interactions among plants that alters plant growth, including those mediated by microorganisms. Allelopathy, besides including competition for resources among plants, is considered to be an important mechanism of plant interference caused by the addition of plant-produced toxins to the plant environm...

Trifolium spp. are native plants in Iran exhibiting good ground cover po-tential. Salinity is a major environmental stress and today, 20% of the world cultivated areas and nearly half of all irrigated lands are affected by salinity. The main aim of this research was to study morphological and physiological adaptations of these native species under different salinity levels for urban landscape u...

Enormous data are available on trade, breeding and larval rearing, nutritional and growth studies and aquarium keeping of the ornamental invertebrates from other countries. In India, studies on ornamental invertebrates are not available. The studies related with the biodiversity of ornamental invertebrates are not available from global level. This paper reviewed the research work on marine orna...

The present study examined women's attentional bias toward ornamental objects in relation to their menstrual phase as well as to motivations of intersexual courtship or intrasexual competition. In Experiment 1, 33 healthy heterosexual women were tested in a bias-assessment visual cuing task twice: once on a high-fertility day (during the ovulatory phase) and once on a low-fertility day (during ...

Bamboos were introduced into Europe from China and Japan in the early 1800s and their cultivation in parks and gardens became quite popular. The first records of scale insects on ornamental bamboos in Europe date to early in the XX century (i.e. Kuwanaspis pseudoleucaspis), but the presence of some species was unknown until recently due to their concealed habit (i.e. Balanococcus kwoni Pellizza...

Elaborate secondary sexual traits, such as the ornamental plumage of birds, may be favored by female choice because they serve as honest indicators of male quality. Elaborate traits are thought to be honest signals because they are expensive to produce and increase predation risk. Here we investigate another potential cost of elaborate traits, i.e., the time and energy required to maintain them...

The knowledge of nutritional requirements in ornamental fish species is essential to improve the productive development; however, the nutritional information of these species is scarce and sometimes this information is extrapolated from results obtained from nonornamental fish species. In ornamental fish, a correct formulation of the diet improve the nutrient digestibility and supply the metabo...
