Polyceratocarpus askhambryan-iringae, an endemic tree species of Annonaceae from the Udzungwa Mountains of Tanzania, is described and illustrated. The new species is identified as a member of the genus Polyceratocarpus by the combination of staminate and bisexual flowers, axillary inflorescences, subequal outer and inner petals, and multi-seeded monocarps with pitted seeds. From Polyceratocarpu...

آرایش کاشت بر خصوصیات رشدی و عملکرد آفتابگردان از طریق تغییر در فضای رشد هر بوته تأثیر می گذارد. ازآنجایی که هیچ گاه صد در صد بذرهای کاشته شده سبز نمی شوند، این سوال وجود دارد که تا چه اندازه ممکن است فاصله بوته را بدون افزایش شدید در رقابت کاهش داد وتا چه حد بوته های مجاور بوته های سبز نشده، ممکن است کاهش عملکرد ناشی از بوته از دست رفته را جبران نمایند. لذا به منظور پاسخ به این سوال، مطالعه ای...

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...

Nutrient losses from residential lawns and landscapes can negatively impact water quality. Information about nutrient leaching from established residential landscapes containing a mixture of woody ornamental plants and turfgrass is limited. The objective of our study was to determine the effect of vegetation cover (turfgrass vs. woody ornamental) on nutrient leaching from established landscapes...

Brevipalpus mites colonize a great number of fruit and ornamental plants. Mite species belonging to this genus have been associated with many plant viruses. Citrus leprosis (CiLV) is the most economically important virus transmitted by B. phoenicis mites. It has recently been shown that ornamental plant species can be alternative hosts of this virus. The high volume of trade and frequent moveme...

The ornamental pet trade is often considered a key culprit for conservation problems such as the introduction of invasive species (including infectious diseases) and overharvesting of rare species. Here, we present the first assessment of the biodiversity of freshwater molluscs in the ornamental pet trade in Singapore, one of the most important global hubs of the ornamental aquarium trade, and ...
