Clostridium difficile is a well-established hospital pathogen. Recently, it has been detected increasingly in patients without hospital contact. Given this rise in community associated infections with C. difficile, we hypothesized that the environment could play an important role in transmission of spores outside the hospital. Lawn samples (311) collected in public spaces in the metropolitan ar...

A study was conducted in northern Colorado to evaluate the effectiveness of two compost products on improvement turfgrass color and quality, necrotic ringspot (NRS) disease suppression, thatch reduction. Two Kentucky bluegrass (Poa pratensis L.) home lawns with a history NRS were chosen for study. Treatments applied twice during 2018 growing season after all plots aerated consisted (a) inoculat...

Turfgrasses are considered an important part of the landscape and ecological system golf courses, sports fields, parks, home lawns. Turfgrass species affected by many abiotic stresses (e.g., drought, salinity, cold, heat, waterlogging, heavy metals) biotic (mainly diseases pests). In current study, seashore paspalum (Paspalum vaginatum Sw.) Tifway bermudagrass (Cynodon transvaalensis Burtt Davy...

Maintaining bee-friendly habitats in cities and suburbs can help conserve the vital pollination services of declining bee populations. Despite label precautions not to apply them to blooming plants, neonicotinoids and other residual systemic insecticides may be applied for preventive control of lawn insect pests when spring-flowering weeds are present. Dietary exposure to neonicotinoids adverse...

Biomass production for energy purposes on agricultural land competes with food production. This is a serious problem, considering the limited availability of farmland, rising demand for varied food products, demand for more organic crop production resulting in considerably reduced yields per area and the need for more environmentally sound agricultural practices meeting long-term sustainability...

The rapid expansion of urbanization has caused land cover change, especially the increasing area of impervious surfaces. Such alterations have significant effects on the soil ecosystem by impeding the exchange of gasses, water, and materials between soil and the atmosphere. It is unclear whether impervious surfaces have any effects on soil bacterial diversity and community composition. In the p...

We describe the reconstitution of exocytotic function through recombination of purified cortical secretory vesicles (CVs) and plasma membrane from sea urchin eggs. CVs were dislodged from a cell surface complex preparation by gentle homogenization in an isotonic dissociation buffer, and purified by differential centrifugation. CV-free plasma membrane fragments were obtained by mechanically disl...

On the expansion of Tapinoma invasive ants in France (Hymenoptera: Formicidae). - The ant magnum has been reported various places southwestern (LENOIR & GALKOWSKI, 2017). This seems to spread rapidly this region from Toulouse Lyon region, as well Loire Valley and Brittany. It is a big problem for example Saumur where people cannot access their lawns. Two other species, T. ibericum darioi, a...
