“…Our findings were consistent with previous results; Precipitation and temperature are consistently highlighted as influential in the distribution of plants (Xu et al, 2013;Springate and Kover, 2014), mainly precipitation exerts primary control of plant productivity and composition in semi-arid and arid land plant community (Passey et al, 1982;Graetz et al, 1988). In the study area, the distribution of S. tenacissima seemed to be driven by a range of predictor variables of which the most important are annual precipitation, and maximum temperature of warmest month.…”

Abstract. Stipa tenacissima L. (Alfa grass) is an important perennial grass species in Tunisia andNorthern Africa which dominates wide arid ecosystems offering multiple services. The focus of this study is to explore how the distribution of suitable habitat for Stipa tenacissima, might shift under climate change. To investigate the potential effects of climate change on the target species we used Maxent modeling algorithm for two representative concentration pathways (RCPs) lower emission scenario (RCP 2.6) and higher emission (RCP 8.5) climate forcing scenarios in 2050 and 2070. Results of the analysis showed a negative impact of climate change on the S. tenacissima ecosystem. There is a decrease in suitable habitat for alfa through time and across space with an increase in greenhouse gas. Suitable habitat was projected to decline through time from 64% to 70% by 2050 for RCP 2.6 and RCP 8.5 respectively and from 86% to 92% by 2070 for RCP 2.6 and RCP 8.5 comparatively to the current state. Across space, when projecting model into the future, the area of predicted suitable habitat of Tunisian alfa grass would dramatically reduce in the central area, and disappear from the Southern area. Therefore, global warming associated with climate change by the years 2050 and 2070 might affect the suitable bioclimatic habitat of S. tenacissima with a severe loss of habitat suitability.

“…Its amount plays an important role in maintaining soil moisture, water penetration in the soil, and http://www.aloki.hu • Although many similar results from other studies were cited to support our abovementioned discussion, there still existed some different aspects between our studies and other ones. For example, Xu et al (2013) documented precipitation and temperature are consistently highlighted as influential in the distribution of plants, while the percentage of slope, silt, sand and the percentage of stone and gravel on the soil surface were more important than temperature in our study. However, it is very difficult to really discern the differences in the results from different studies, because the vegetation, soil, and topography relationship is very complicated per se; the aims of the other studies and the associated measures taken were very different and the local conditions also varied from one study to another.…”

Abstract. Ferula ovina is a forage species, and of the species that is very important in soil conservation and water protection in the rangelands. It has become an endangered species in Iran due to regular cutting and overgrazing. The focus of this study is to investigate the effect of ecological factors on distribution of F. ovina in the study area. Samples were collected from three habitats (sites) where F. ovina was present along with three sites which did not have it. Three 150 m transects were established based on randomsystematically method on each site. On each transect, 10 square plots (2×2 m) were set up, and soil surface features were measured. Climatologic factors were assessed and physiographic factors were extracted for each site. Soil samples were collected from a 0-30 cm depth for each transect, and the values of soil were determined through laboratory analysis. According to the results, a significant difference was found for the parameters of elevation, slope, aspect, temperature, EC, pH, OC, phosphorus, clay, silt and sand (P≤0.01) between habitats where F. ovina were present and absent. Results of discriminant analysis suggested that the amount of sand and gravel on soil surface, phosphorous, clay, and EC were effective factors in the distribution of target species.

“…Increased inter-annual variability in summer and winter precipitation, as well as in summer temperatures, is also expected (Giorgi and Lionello, 2008). Changes in atmospheric CO 2 concentration, temperature and precipitation patterns are expected to affect plant productivity in a complex manner due to a set of mechanisms and interactions at different scales from the individual leaves to agroecosystems (Hatfield and Prueger, 2011;Xu et al, 2013). For grasslands, there are also important complicating factors such as plant competition and other plant-plant interactions, perennial growth habits, seasonal productivity patterns, and plant-animal interactions (Porter et al, 2014).…”

Climate change and its eﬀects on grassland productivity vary across Europe. The Mediterranean and Nordic regions represent the opposite ends of a gradient of changes in temperature and precipitation patterns, with increasingly warmer and wetter winters in the north and increasingly warmer and drier summers in the south. Warming and elevated concentration of atmospheric CO2 may boost forage production in the Nordic region. Production in many Mediterranean areas is likely to become even more challenged by drought in the future, but elevated CO2 can to some extent alleviate drought limitation on photosynthesis and growth. In both regions, climate change will aﬀect forage quality and lead to modiﬁcations of the annual productivity cycles, with an extended growing season in the Nordic region and a shift towards winter in the Mediterranean region. This will require adaptations in defoliation and fertilization strategies. The identity of species and mixtures with optimal performance is likelyto shift somewhat inresponse to altered climate and management systems. Itis argued that breeding of grassland species should aimto (i) improve plantstrategies to cope with relevant abiotic stresses and (ii) optimize growth and phenology to new seasonal variation, and that plant diversity at all levels is a good adaptation strategy
