Phylogenetic relationships and intraspecific diversity of a North Patagonian Fescue: evidence of differentiation and interspecific introgression at peripheral populations por Lopez, Aldana, Azpilicueta, Maria Marta, Lopez, Dardo Ruben, Siffredi, Guillermo Lorenzo, Marchelli, Paula

“…The Patagonian steppe, the largest and southernmost dryland ecosystem in South America, is characterized by natural rangelands dominated by grasses. Festuca pallescens is a keystone species with a wide distribution in Patagonia over diverse environments reaching the extreme arid zones in the Somuncura plateau, a biogeographical island. …”

Water Balance Trends along Climatic Variations in the Mediterranean Basin over the Past Decades por Unnisa, Zaib, Govind, Ajit, Lasserre, Bruno, Marchetti, Marco

“…Also, the water balance in other land use systems (rain-fed, irrigated croplands, and rangelands) was either negative or near zero. As a whole, the basin’s average annual P was ≈538 mm yr−1, the annual average AET was ≈415 mm yr−1, and the runoff (Q) was equivalent to 123 mm yr−1, which shows a strong influence of ET over the region. …”

Valuing ecosystem services for conservation and development purposes: A case study from Kenya por Silvestri, Silvia, Zaibet, L., Said, Mohammed Yahya, Kifugo, S.C.

“…In particular, the paper identifies services that will be lost if a particular part of landscape is modified: e.g. benefits for livestock and wildlife can be affected by the lack of conservation of corridors and rangelands, while water supply and irrigated crops can be compromised by increased water demand as result of human population pressure mainly at the upstream sub-catchments. …”

Reducing uncertainty in nitrogen budgets for African livestock systems por Rufino, Mariana C., Brandt, P., Herrero, Mario, Butterbach-Bahl, Klaus

“…No flows between croplands–livestock and rangelands reflect the lack of data. Joint efforts are needed for spatial data collection of livestock data, crowdsourcing appears to be a promising option. …”

Behaviour and dietary preferences of browse species by sheep on natural pasture in Ninh Thuan province in the south-central region of Vietnam por Andersson, Maria

“…The Ninh Thuan province consists of large areas of natural rangelands, which are used for animal grazing. The area is unique in Vietnam because of the hot and dry climate, which means that the vegetation is limited and the botanical composition very special. …”

Diversity patterns in the steppe of Argentinean Southern Patagonia: Environmental drivers and impact of grazing por Peri, Pablo Luis, Lencinas, María Vanessa, Martínez Pastur, Guillermo José, Wardell-Johnson, Grant W., Lasagno, Romina Gisele

“…Erosion and degradation processes have occurred in several areas of Patagonia mainly due to an overestimation of the carrying capacity of these rangelands. In this chapter we review patterns of plant and insect diversity in relation to environmental drivers and grazing impact in the steppe of Argentinian South Patagonia. …”
