“…La importancia biogeográfica de la SARU se demuestra con el registro de 37 especies de ranas Pristimantis, representando el 46% (80 spp) reportadas para la Cuenca Alta de los ríos Napo, Pastaza y Santiago; 26 especies son endémicas, que representa el 51% de endemismo de la vertiente oriental [7].…”

“…Su extraordinaria radiación adaptativa en los Andes, es atribuida a su peculiar sistema reproductivo de desarrollo directo, sumado a las barreras geográficas y adaptabilidad a gran variedad de hábitats [3,4]. La mayor concentración de especies de ranas Pristimantis ocurre en los bosques andino montanos [2,3,5], sin embargo, la creciente fragmentación de los hábitats naturales ha puesto en peligro de extinción a numerosas especies [6][7][8].…”

“…Humans have a large trajectory of changing landscapes, being one of the most highlighted drivers of biodiversity loss (Ellis et al, 2010). Recent studies have shown the direct relation between the changes in the use of land and changes in bird (Rittenhouse et al, 2012; Dorresteijn et al, 2015), mammal (Sieber et al, 2015; Torre et al, 2015; Cisneros, Fagan & Willig, 2015), amphibian (Nori et al, 2015) and invertebrate communities (Ngai et al, 2008; Wagner, Krauss & Steffan-Dewenter, 2013). Therefore, when the dates of records in a biodiversity database coincide with, or precede, important changes in land use, neglecting obsolescence of the data could allow for a considerable amount of noise in the primary data used to estimate potential distribution areas or diversity patterns.…”

Biodiversity data obsolescence and land uses changes

BackgroundPrimary biodiversity records (PBR) are essential in many areas of scientific research as they document the biodiversity through time and space. However, concerns about PBR quality and fitness-for-use have grown, especially as derived from taxonomical, geographical and sampling effort biases. Nonetheless, the temporal bias stemming from data ageing has received less attention. We examine the effect of changes in land use in the information currentness, and therefore data obsolescence, in biodiversity databases.MethodsWe created maps of land use changes for three periods (1956–1985, 1985–2000 and 2000–2012) at 5-kilometres resolution. For each cell we calculated the percentage of land use change within each period. We then overlaid distribution data about small mammals, and classified each data as ‘non-obsolete or ‘obsolete,’ depending on both the amount of land use changes in the cell, and whether changes occurred at or after the data sampling’s date.ResultsA total of 14,528 records out of the initial 59,677 turned out to be non-obsolete after taking into account the changes in the land uses in Navarra. These obsolete data existed in 115 of the 156 cells analysed. Furthermore, more than one half of the remaining cells holding non-obsolete records had not been visited at least for the last fifteen years.ConclusionLand use changes challenge the actual information obtainable from biodiversity datasets and therefore its potential uses. With the passage of time, one can expect a steady increase in the availability and use of biological records—but not without them becoming older and likely to be obsolete by land uses changes. Therefore, it becomes necessary to assess records’ obsolescence, as it may jeopardize the knowledge and perception of biodiversity patterns.

“…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.
