Concern over declining pollinators has led to multiple conservation initiatives for improving forage for bees in agroecosystems. Using data available through the Pollinator Library (npwrc.usgs.gov/pollinator/), we summarize plant-pollinator interaction data collected from 2012-2015 on lands managed by the U.S. Fish and Wildlife Service and private lands enrolled in U.S. Department of Agricultur...

Melilotus is an important genus of legume plants and an herbage with excellent nitrogen fixation; it can tolerate extreme environmental conditions and possesses important medicinal value. However, there is limited genetic information about the genus; thus, we analysed four chloroplast loci (rbcL, matK, psbA-trnH and trnL-F) and one nuclear region (ITS) to determine the genetic diversity of 199 ...

The aim of this study was to evaluate the lipolytic potential of solutions used in the practice of cosmetic mesotherapy to stimulate lipolysis, cause local fat reduction and reduce the appearance of cellulite. The mesotherapy solutions were tested in a human fat cell assay using the fold induction of glycerol generation as a measure of lipolysis. The following mesotherapy solutions were tested:...

Melilotus officinalis is known to contain several types of secondary metabolites. In contrast, the carotenoid composition this medicinal plant has not been investigated, although it may also contribute biological activities drug, such as anti-inflammatory effects. Therefore, study focuses on isolation and identification carotenoids from Meliloti herba effect isolated (all-E)-lutein 5,6-epoxide ...

In recent years, the addition of microorganisms such as Plant Growth-Promoting Bacteria (PGPB) and mycorrhiza are becoming more popular, both in research as well as in practical use. While inoculants are usually not necessary for plants cultivated outdoors on biologically active soil, they can be useful on sterile substrates, newly created artificial landscapes, and also in soils that have been...

Current landfill regulations provide for the responsible management of solid waste and a safer alternative to the outdated practices of open or illegal dumping. Aside from imparting aesthetic value, natural or planted vegetation on landfill sites has an important role in erosion control and removal of contaminants, and may also be used in leaching treatment. The use of leachate for the irrigati...

The microbiome in plant-soil systems has a significant influence promoting plant growth. Despite this, the extent of selectivity that exerts on continuum between soil and internal tissues is not well understood. This study analysed root legume, Melilotus officinalis (L.) Pall., sweet clover, focused dynamic shifts microbial community structure through niches bulk soil, rhizosphere, periderm, ph...

A field study was conducted to increase our understanding of diel activity patterns of Colaspis brunnea (F.) and Colaspis crinicornis Schaeffer (Coleoptera: Chrysomelidae) in key crop habitats. Within 24-h periods, C. brunnea was sampled in clover fields (primarily red clover, Trifolium pretense (L.), with some sweet clover, Melilotus officinalis (L.) Pallas, and downy brome, Bromus tectorum (L...

Bumblebees (Bombus spp.) and honeybees, Apis mellifera, both use odour cues deposited on flowers by previous visitors to improve their foraging efficiency. Short-lived repellent scents are used to avoid probing flowers that have recently been depleted of nectar and/or pollen, and longer-term attractant scents to indicate particularly rewarding flowers. Previous research has indicated that bumbl...

Respiration in support of N(2) fixation by rhizobia in legume root nodules depends on an adequate supply of O(2), but excessive O(2) can damage nitrogenase, the key enzyme. The movement of O(2) into and within the nodule is driven by gradients in the concentration of O(2) or in the oxygenation of the O(2)-carrier, leghaemoglobin. Steeper gradients may increase flux to the sites of respiration, ...
