Transplanted sagebrush "wildlings" exhibit higher survival than greenhouse-grown tubelings yet both recruit new plants.

Published in BMC ecology and evolution

Land uses such as crop production, livestock grazing, mining, and urban development have contributed to degradation of drylands worldwide. Loss of big sagebrush (Artemisia tridentata) on disturbed drylands across the western U.S. has prompted massive efforts to re-establish this foundational species. There has been growing interest in avoiding the ...

Impact of soil and water conservation structures on the spatial variability of topsoil moisture content and crop product...

Plant available soil moisture and its spatial variability is among the most important limiting factors for crop and livestock productivity in semi-arid Ethiopia. The objectives of this study were therefore: 1) to measure the effects of land use and slope gradient on spatial variability of topsoil moisture content. 2) to analyze the variability of t...

It’s All About the Climb: Consistent Individual Differences in Cattle Behavior and How they Relate to Grazing Distributi...

Consistent individual differences (CIDs) in animal behavior can be measured in assays that target specific behaviors which are assumed to represent underlying stable traits. These are linked to various outcome measures, such as how animals use space and/or forage in natural environments. Consistent individual behavioral variation in beef cattle has...

Soil properties of thickets and adjacent land use types in coastal savanna landscape of Ghana

Thicket vegetation may be of great importance in soil carbon (C) storage and in provision of other ecosystem services such as soil erosion control and biodiversity conservation. However, it is less studied in tropical ecosystems due to limited understanding of its ecological importance. This study reports soil C pools and nutrient concentrations [n...

The role of remote sensing in tropical grassland nutrient estimation: a review

Published in Environmental Monitoring and Assessment

The carbon ( C ) and nitrogen ( N ) ratio is a key indicator of nutrient utilization and limitations in rangelands. To understand the distribution of herbivores and grazing patterns, information on grass quality and quantity is important. In heterogeneous environments, remote sensing offers a timely, economical, and effective method for assessing f...

Seed Productivity of Natural Vegetation at UoD Campus as Affected by Mowing Frequency

Published in IOP Conference Series: Earth and Environmental Science

Since 2000, there has been a noticeable increase of overgrazing in Kurdistan region of Iraq, particularly in Duhok governorate, as a result of the widespread movement of livestock (sheep and goats) by animal breeders from the middle of Iraq, particularly from the Nineveh steppes, to graze in Kurdistan region constantly from early spring to late sum...

Effects of prosopis juliflora on plant diversity on rangeland in Shilabo District, Somali Regional State, Ethiopia.

Published in Heliyon

Shilabo District of Somali Regional State in Ethiopia is economically important for livestock production. The indigenous pasturelands are increasingly being invaded by Prosopis juliflora, thereby threatening their livestock production capacity. However, the ecological impact of Prosopis' invasion has yet to be investigated. This study was conducted...

Estimating the runoff response from hillslopes treated with soil and water conservation structures in the semi-arid Ethi...

Planning and management of water resources is crucial to enhance agricultural productivity and ensure food security in drylands. For this, adaptable and reliable runoff prediction models are urgently needed to support water harvesting and irrigation development. In this study we explored the potential of the runoff Curve Number (CN) method to estim...
