Triatominae of the semi-arid Chaco in central Argentina
Acta Tropica, 2021The epidemiological scenario in central Argentinian Chaco region shows persistence of Triatoma infestans domestic populations in endemic areas, with control interventions historically affected by the economic instability of the region. Considering this situation, we aimed to (i) update the information regarding to the diversity of triatomines present ...

Denitrification in a semi-arid grazing ecosystem
Oecologia, 1998The effect of large herbivores on gaseous N loss from grasslands, particularly via denitrification, is poorly understood. In this study, we examined the influence of native migratory ungulates on denitrification in grasslands of Yellowstone National Park in two ways, by (1) examining the effect of artificial urine application on denitrification, and (2)

Hydrocollapse of Semi-arid Soils
Indian Geotechnical Journal, 2015Problematic soils are those that make the construction of structures extremely difficult. They include collapsible soils which are widely distributed in North America, Europe, Russia and Asia. They show low dry density and moisture content in all testing schedule due to presence of cementation bonds or loess structure especially at unsaturated state in

VEGETATION PATTERN FORMATION IN A SEMI-ARID CLIMATE
International Journal of Bifurcation and Chaos, 2011A partial bifurcation diagram of a reaction–diffusion type model of two-dimensional vegetation patterns in a semi-arid climate is computed using numerical continuation techniques. In previous studies with this model, it has been shown that two positive feedbacks (the infiltration feedback and precipitation feedback) may influence the type of ...

Semi-Arid Regions in the World
2019This chapter utilizes the term steppe as conceived by African and Asian scientists to include all vegetation types within what has been designated as the semiarid region. While precipitation alone is considered to be a less exact indicator than indicators based on evapotranspiration, it is often used as a guide to arid climates subdivisions.

Irrigation in semi-arid regions
Outlook on Agriculture, 1967A land area can be considered semi-arid if it has an annual rainfall of less than 15 inches and if the evaporation from a water surface exceeds 45 inches. Such areas, under irrigation, can be highly productive agriculturally and can also provide congenial living conditions.

Abstract The ecology of the arid and semi-arid regions of East Africa is essentially the ecology of subsistence pastoralism. Pastoralists and their herds are ubiquitous in the drier parts of East Africa. Pastoralists need these areas for their survival and, in tum, significantly affect them.

Phototrophic microorganisms are mostly endolithic or hypolithic in the more extreme arid environments and are here restricted to situations where sufficient moisture is retained for occasional growth to occur. Slightly less extreme environments frequently have biological soil crusts.

Arid and Semi-Arid Geomorphology
2013Based on four decades of research by Professor Andrew Goudie, this volume provides a state-of-the-art synthesis of our understanding of desert geomorphology. It presents a truly international perspective, with examples from all over the world. Extensively referenced and illustrated, it covers such topics as the importance of past climatic changes, the ...
