Temperature-Size Rule (TSR) is a phenotypic body size response of ectotherms to changing temperature. It is known from the laboratory studies, but seasonal patterns in the field were not studied so far. We examined the body size changes in time of rotifers inhabiting activated sludge. We hypothesize that temperature is the most influencing parameter in sludge environment, leading sludge rotifer...

Abstract. Scientific novelty and practical significance. The increasing rates of soil degradation processes in the southern regions Russia make it urgent to increase productivity agricultural land, stabilize ecosystems restore potentially valuable forage vegetation. Phytomeliorative reconstruction low-productive lands is great importance for ensuring sustainable development region national food...

A former lectotype for Bromus cincinnatus Ten. (Poaceae) has been superseded, as it is in serious conflict with the protologue. Another element of protologue designated effective lectotype. The new identified coespecific intermedius Guss., a Mediterranean species L. subg. Bromus. combination Helictochloa panormitana (Lojac.) Romero Zarco proposed originally described Avena australis Parl., nom....

Exotic invasive species can directly and indirectly influence natural ecological communities. Cheatgrass (Bromus tectorum) is non-native to the western United States and has invaded large areas of the Great Basin. Changes to the structure and composition of plant communities invaded by cheatgrass likely have effects at higher trophic levels. As a keystone guild in North American deserts, graniv...

The antifungal effect of 10 plant extracts viz., Thevetia peruviana, Ocimum basilicum, Piper betel, Murraya koenigii, Chrysanthemum coronarium, Polyalthia longifolia, Catharanthus roseus, Pelargonium graveolens, Moringa officinalis and Lawsonia inermis were evaluated by poisoned food technique against Rhizoctonia solani Kuhn, the causal organism of sore shin disease of tobacco. Among all the pl...

PREMISE OF THE STUDY Bromus tectorum (Poaceae) is an annual grass species that is invasive in many areas of the world but most especially in the U.S. Intermountain West. Single-nucleotide polymorphism (SNP) markers were developed for use in investigating the geospatial and ecological diversity of B. tectorum in the Intermountain West to better understand the mechanisms behind its successful inv...

A field lysimeter study with bare ground and five different ground covers was established to evaluate the effect of forage grasses on the fate and transport of two herbicides in leachate. The herbicides were atrazine (ATR; 2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) and isoxaflutole [IXF; 5-cyclopropyl-4-(2-methylsulfonyl-4-trifluormethyl-benzoyl)isoxazole], which has the commercial ...

Ten ruminally and duodenally cannulated (326 _+ 28 kg) and four esophageally fistulated (394 k 23 kg) steers grazing cool-season pasture throughout the growing season were used to evaluate the influence of Aspergillus oryzae fermentation extract (AO) supplementation on intake, forage nutrient utilization, and duodenal amino acid flow. Steers grazed a predominately smooth brome (Bromus inermis L...

Weeds are a major problem in seeding rangeland and cropland to native grasses. However, many immature weedy forbs and grasses are palatable to cattle. Research was conducted using yearling cattle for weed control in big bluestem (Andropogon gerardii var. gerardii Vitman) seedings (1987, 1988) at Mead, Nebraska on a Sharpsburg silty clay loam (fine, montmorillonitic, mesic Typic Argiudoll) soil....
