Shifts in sage-grouse arthropod food sources across grazing and environmental gradients in upland meadow communities.

Groundwater dependent systems are extremely important habitats for a wide variety of taxa in the Great Basin of North America. The impacts of grazing on these habitats cause shifts in resources and subsequent change in species composition. The Greater sage-grouse, a keystone species of Great Basin ecosystems, rear offspring in these areas during spring and summer months using forbs and arthropods.

Ecosystem carbon and nitrogen gains following 27 years of grazing management in a semiarid alluvial valley.

Soils in semiarid riparian ecosystems have large carbon (C) stocks that promote water and nutrient availability for productive plant communities consumed by grazing animals. Changes to riparian hydrologic conditions caused by channel incision result in different edaphic conditions and a greater abundance of upland plant species that may be associated with lower soil C stocks. Using riparian meadows alongside Maggie Creek in central Nevada, we show that 27 years of modified grazing practices can repair ecosystem processes and increase the C stocks.

Magnetic FB injuries: an old yet unresolved hazard.

Rationale And Aim: Among foreign bodies causing injuries in children, magnets have been reported to cause serious complications and being life-threatening. The aim of this study is to design a risk profile and an epidemiological figure of such injuries, for being used for prevention.

Methods: Data on 366 injuries have been collected from public surveillance databases and from published scientific literature, and compared with the data of the Susy Safe registry, which is a pan-European registry of foreign bodies injuries co-funded by the European Commission.

Foreign bodies in the airways: a meta-analysis of published papers.

Background: Very recently, some attempts have been made to start a systematic collection of foreign bodies (FB) in view of using them to characterize the risk of chocking in terms of size, shape and consistency of the FB. However, most of the epidemiologic evidence on foreign bodies in children comes from single-center retrospective studies, without any systematic geographical and temporal coverage. This paper is aimed at providing an estimate of the distribution of foreign body's injuries in children according to gender, age, type of FB, site of obstruction, clinical presentation, diagnostic/therapeutic procedures, complications, as emerging from a meta-analytic review of published papers.

Choking injuries and food products containing inedibles: a survey on mothers' perception in the United Kingdom.

Although recent investigations showed no specific hazard resulting from Food Products Containing Inedibles as compared to the wider category of toys, in view of recent findings and subsequent study of the European Registry of Foreign Bodies Injuries, a potential threat has been identified in a lack of parental supervision in the event of injury. Indeed, according to the report of the European Registry of Foreign Bodies Injuries, almost 80% of the injuries occur under parental supervision, which is obviously inadequate. The aim of this short contribution is to present the results of a Computer Assisted Personal Interviewing survey in the UK focused on the knowledge that mothers, fathers and other adults have on the issue of choking.
