conclusions the constituents of anbarnesa smoke mainly possess antibacterial, anti-inflammatory, and growth inhibition effects on cancer cells. results literature review reveals that annas (anbarnesa smoke) enhances wound healing, decreases scar formation, inhibits growth of cancer cells (hela and kb) and has antimicrobial properties. also, annas combined with propylene glycol is nontoxic in 1/...
Abstract To investigate the role of cow dung in soil reclamation and bio assimilation along with accumulation heavy metals earthworm (P. posthuma) (N=900) earthworms were used treatment groups CD-soil mixture different proportion designed. Nonlethal doses lead acetate cadmium chloride added groups. Mature P. posthuma released each experimental pot maintaining favorable conditions. The pH, carbo...
In past decades, ecological services and functions of alpine grassland in the Three-River Headwater Region (TRHR), Qinghai-Tibetan Plateau, have been severely degraded due to overgrazing and overuse of yak dung as a fuel. Therefore, the eco-migration project has been implemented by the national government for improving eco-environmental quality in this region. This paper examines the carbon cyc...
To understand the dynamics of spatially structured populations, we need to know the level of movements at different spatial scales. This paper reports on Aphodius dung beetle movements at two scales: movements between dung pats within pastures, and movements between pastures. First, I test an assumption common to many recent models of spatially structured populations – that the probability of a...
When the moon is absent from the night sky, stars remain as celestial visual cues. Nonetheless, only birds, seals, and humans are known to use stars for orientation. African ball-rolling dung beetles exploit the sun, the moon, and the celestial polarization pattern to move along straight paths, away from the intense competition at the dung pile. Even on clear moonless nights, many beetles still...
Biodiversity drives ecological functioning, ultimately providing ecosystem services. Ecosystem processes are favored by greater functional diversity, particularly when groups of functionally different species interact synergistically. Many such functions performed insects, among which dung beetles stand out for their important role in decomposition. However, anthropogenic disturbances negativel...
اثر تیمارهای گوناگون کودهای آلی، زیستی و شیمیایی روی ویژگی های زیستی شته جالیز (aphis gossypii glover) در شرایط آزمایشگاه با دمای 1±25 درجه سلسیوس، رطوبت 5±60 درصد و دوره ی نوری 16 ساعت روشنایی و 8 ساعت تاریکی مورد بررسی قرار گرفت. تیمارها شامل، control، dung، vermicompost، npk، npknb، npkpb و npknbpb بود. افزون بر این اثر این تیمارها روی سطح مواد غذایی گیاه خیار و مقاومت آنتی زنوزی آن نسبت به...
Various kinds of pathogenic bacteria derived from the intestinal tract of animals exist in compost material like cow dung. In order to sterilize the pathogenic bacteria completely in compost material, the cow dung was put into a heat treatment machine in pilot plan, and harmless condition in short time was examined. The results indicated, pathogenic indicator bacteria such as coliform bacteria,...
Madagascar has a rich fauna of dung beetles (Scarabaeinae and Aphodiinae) withalmost 300 species described to date. Like most other taxa in Madagascar, dung beetles exhibit an exceptionally high level of endemism (96% of the species). Here,we review the current knowledge of the origin and diversification of Malagasy dung beetles. Based on molecular phylogenies, the extant dung beetles originate...
Scarabaeine dung beetles are the dominant dung feeding group of insects and are widely used as model organisms in conservation, ecology and developmental biology. Due to the conflicts among 13 recently published phylogenies dealing with the higher-level relationships of dung beetles, the phylogeny of this lineage remains largely unresolved. In this study, we conduct rigorous phylogenetic analys...
