“…This result matches that of Torres et al (2014), who found that the response of the probability of presence of all the analyzed amphibian species in Argentinean northwestern Dry Chaco to woody biomass was negative. The importance of open habitats for Leptodactylus species suggests that these species evolved in landscapes which were more similar to open habitats than to forests, a scenario proposed for the pre-European landscape of the Chaco (Morello & Saravia Toledo, 1959a; Morello & Saravia Toledo, 1959b; Adámoli et al, 1972; Adámoli et al, 1990; Bucher & Huszar, 1999), in which the substantial contemporary woodland advance has been a result of domestic livestock overgrazing (Morello & Saravia Toledo, 1959a; Morello & Saravia Toledo, 1959b; Adámoli et al, 1990).…”

Thus, savannas might have been an important cover type where part of the chacoan biota evolved (Torres et al, 2014). …”

“…Thus, analyses assessing the impacts of LULC on the geographic patterns of distribution of taxonomic groups are of major importance, since different taxa are affected in different ways by land use and by its changes (Schulze et al, 2004; Leroux et al, 2010; Dallimer et al, 2012). Amphibians exhibit high richness in the Dry Chaco, which has been scarcely studied in association to land cover changes (Torres et al, 2014). This fact is worrying since amphibians have become a high-priority group for conservation efforts (de Pous et al, 2010; Urbina-Cardona & Flores-Villela, 2010; Trindade-Filho et al, 2012; Nori et al, 2013; Nori et al, 2015) due to the concern about declines in their populations, and amphibian species extinctions around the world (Young et al, 2001).…”

Subtropical dry forests are among the most vulnerable biomes to land transformation at a global scale. Among them, the Dry Chaco suffers an accelerated change due to agriculture expansion and intensification. The Dry Chaco ecoregion is characterized by high levels of endemisms and species diversity, which are the result of a variety of climates and reliefs, allowing a wide variety of environments. The amphibian group exhibits a high richness in the Dry Chaco, which has been barely studied in relation to land cover changes. We used ecological niche models (ENMs) to assess the potential geographic distribution of 10 Leptodactylus species (Anura, Leptodactylidae), which are mainly distributed within the Dry Chaco. We characterized these distributions environmentally, analyzed their overlap with land cover classes, and assessed their diversity of ecoregions. Also, we evaluated how these species potential distribution is affected by the transformation of land, and quantified the proportional area of the potential distribution in protected areas. We found that temperature seasonality is the main constraint to the occurrence of the species studied, whose main habitats are savannas, grasslands and croplands. The main threats to these species are the effects of climate change over spatial patterns of seasonality, which could affect their breeding and reproduction mode; the loss of their natural habitat; the exposure to contaminants used by intensive agriculture and their underrepresentation in protected areas.

“…Land use/cover change via altering habitat area and spatial distribution of habitat patches affect the structure and spatial heterogeneity of a landscape (Broadbent et al 2012). Landscape changes and habitat fragmentation in protected areas and ecologically sensitive regions can have negative impacts on wildlife populations (Lian et al 2011;Torres et al 2014).…”

Caucasian black grouse (Tetrao mlokosiewiczi) is on the 'red' list of species of high conservation concern as nearest threatened (NT) and also in level (I) of Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The black grouse distribution range in Iran is restricted to the Arasbaran region, Northwest of Iran, and the populations and range of this specialist bird species have been declining over the last decades. Management of forest and grassland structures is important for black grouse population survival. The main goals of this study were to monitor and quantify the landscape pattern changes in Caucasian black grouse habitat in the Arasbaran biosphere reserve in two periods of 14 years (1987-2001) and 10 years (2001-2011). For quantifying landscape pattern changes, various landscape metrics were derived by spatial analysis software FRAGSTATS 3.3, including NP (number of habitat patches), LPI (largest patch index) and TE (total edge). The results indicated that the proportion of forest decreased from 39.95 to 31.95% and the proportion of grassland decreased from 44.45 to 38.44% in the 24-year span. NP of forests increased in the first period and decreased in the second period of study. TE of dense forest at altitude above 1800 m decreased. Reduction of forest edge is an indicator of reduction in habitat availability for Caucasian black grouse which use the forest edge for living, lekking and hatching in upland. Our results provided quantitative data on habitat loss and fragmentation in the Arasbaran biosphere reserve and indicated negative impacts of the landscape structure changes on Black grouse habitat.
