Rangelands provide the main forage resource for livestock in many parts of the world, but maintaining long-term productivity and providing sufficient income for the rancher remains a challenge. One key issue is to maintain the rangeland in conditions where the rancher has the greatest possibility to adapt his/her management choices to a highly fluctuating and uncertain environment. In this stud...

Woody biomass dynamics are an expression of ecosystem function, yet biomass estimates do not provide information on the spatial distribution of woody vegetation within the vertical vegetation subcanopy. We demonstrate the ability of airborne light detection and ranging (LiDAR) to measure aboveground biomass and subcanopy structure, as an explanatory tool to unravel vegetation dynamics in struct...

Conversion of rangelands into cultivated land is one of the main challenges affecting the management of rangelands in Ethiopia. In order to inform policy makers about trends in land-use conversion, this study examined the drivers, trends, and impacts of land conversions in five locations selected in the Borana rangelands of Southern Ethiopia. This study integrated survey interviews from agro-pa...

Weeds and invasive plants know no borders have collectively impacted many ecosystems worldwide, including croplands, forests, grasslands, rangelands, wetlands, riparian areas. Losses continue to mount, affecting yield productivity, species diversity, ecosystem services, with both short- long-term repercussions on the sustainability of plant animal communities livelihoods many. New emerging plan...

The behaviour of five landscape fire models (CAFE, FIRESCAPE, LAMOS(HS), LANDSUM and SEMLAND) was compared in a standardised modelling experiment. The importance of fuel management approach, fuel management effort, ignition management effort and weather in determining variation in area burned and number of edge pixels burned (a measure of potential impact on assets adjacent to fire-prone landsc...

There is growing evidence of escalating wildlife losses worldwide. Extreme wildlife losses have recently been documented for large parts of Africa, including western, Central and Eastern Africa. Here, we report extreme declines in wildlife and contemporaneous increase in livestock numbers in Kenya rangelands between 1977 and 2016. Our analysis uses systematic aerial monitoring survey data colle...

background : pseudomonas aeruginosa , as an etiological agent, has a prominent infection role in serious burned patients. burned patients usually treated with antiseptic ointments such as silver sulfadiazine (ssd). this study evaluated the effectiveness of 1% ssd and different concentrations of silver nitrate solution (sns) on resistant isolates of p. aeruginosa .   methods : three groups of p....

Long term, high quality estimates of burned area are needed for improving both prognostic and diagnostic fire emissions models and for assessing feedbacks between fire and the climate system. We developed global, monthly burned area estimates aggregated to 0.5 spatial resolution for the time period July 1996 through mid-2009 using four satellite data sets. From 2001–2009, our primary data sourc...

Burns form 5-12% of all traumas. About 2,200 of patients are annually hospitalized in Lithuania. In most cases people of the employable age get burned. The treatment is often long-lasting, and afterwards recovered patients often have invalidity from burn sequels. The mortality of hospitalized burned patients is about 10%. The most common causes of death are pulmonary edema, pneumonia, sepsis an...
