“…In the generated ecological niche model, the most important variables for determining C. tatouay presence were average annual temperature (responsible for 52.3% of the variance), and precipitation in driest month (28.3%). These variables were similar to other models for the species, like presented by Abba et al (2012) and Coitiño et al (2013).…”

“…We present here more records of C. tatouay for Pampas region than Anacleto et al (2006) for all Brazil. Exactly why this is so requires further consideration, since the species seems genuinely uncommon in Pampas landscapes in neighboring Argentina and Uruguay (Abba et al, 2012;Coitiño et al, 2013).…”

“…An assessment of potential geographic ranges of armadillos in Brazil (Anacleto et al, 2006) highlighted the small number of C. tatouay records, and suggested that Brazilian Pampa was not a favored habitat. Indeed, C. tatouay does seem relatively uncommon in this habitat, except in Uruguay, the southern limit of its distribution, where some 10 records are available from the Pampas (Coitiño et al, 2013). There are few ecological data from the northernmost part of the range of C. tatouay.…”

ABSTRACT. Cabossous tatouay Desmarest, 1804 is considered a rare species in southern South America, and Rio Grande do Sul State, Brazil, records of the species are scarce and inaccurate. This study reports 40 localities for C. tatouay, and provides a map of the species' potential distribution using ecological niche modeling (ENM). The ENM indicated that in this region C. tatouay is associated with open grasslands, including the areas of "Pampas" and the open fields in the highlands of the Atlantic Forest. This study contributes to the information about the greater naked-tailed armadillo in southern Brazil, and provides data key to its future conservation.

“…Estos modelos trabajan sobre la idea del nicho potencial o fundamental de las especies (Hutchinson 1957) y pueden contribuir a entender la adaptabilidad y las preferencias climáticas de las especies vegetales (Scheldeman et al 2006), a generar estrategias para la conservación (Coitiño et al 2013), a llenar los vacíos de colección ) y a evaluar el daño potencial de las especies invasoras (Biganzoli et al 2013;Heit et al 2013;Young et al 2013;Vilatersana et al 2016). El presente estudio tiene como objetivo indagar sobre las variables climáticas (o ambientales) que podrían influir en la distribución actual, y bajo un escenario de cambio climático, de cinco especies del género Stevia, en el noroeste argentino.…”

R��. La elevada biodiversidad y riqueza específica, junto con una gran variedad de ecosistemas, convierten al noroeste de la Argentina (NOA) en un área adecuada para estudiar los posibles efectos del cambio climático sobre la distribución de los organismos. Asteraceae es una familia de plantas con flores bien representada en esta área; en especial, el género Stevia, con 25 especies que habitan diferentes ambientes. Los objetivos de este estudio fueron: 1) modelar la aptitud de hábitat para cinco especies de Stevia que habitan el noroeste argentino, y 2) proyectar dicha aptitud bajo un posible escenario de emisión de gases de efecto invernadero para el año 2050. Se analizaron las especies S. alpina, S. breviaristata, S. minor, S. vaga y S. yaconensis. Los resultados mostraron que, al comparar los mapas basados en condiciones climáticas actuales y futuras, todas las especies de Stevia sufrirían modificaciones en sus rangos de aptitud. Las tendencias observadas en ambos escenarios climáticos futuros son similares, aunque más drásticas en el modelo rcp8.5. El área de aptitud de Stevia alpina, S. breviaristata y S. minor se vería reducida, mientras que la de S. vaga y S. yaconensis aumentaría. Excepto S. minor, las especies presentaron una tendencia principal a migrar del este al oeste, un fenómeno conocido como desplazamiento en altura. Stevia minor sería la especie más afectada en un escenario de mayor emisión de gases; sufriría una reducción mayor a 80% para valores de aptitud superiores a 0.65. [Palabras clave: distribución potencial, nicho climático]A��. Climatic change and species modeling of Stevia (Asteraceae) in northwestern Argentina. The high biodiversity and species richness, along with a great variety of ecosystems, turn northwestern Argentina into an adequate area for study the possible effects of climate change on the distribution of organisms. Asteraceae is a well-represented family of flowering plants in this area; especially, the genus Stevia, with 25 species which inhabit different environments. The goals of this study were: 1) to model habitat suitability for five species of Stevia distributed in northwestern Argentina, and 2) to project such suitability under a possible greenhouse gas emission scenario by 2050. Species S. alpina, S. breviaristata, S. minor, S. vaga and S. yaconensis were analyzed. Results showed that, when comparing maps based on current and future climatic conditions, all Stevia species would undergo changes in their fitness ranges. The trends observed in both future climate scenarios are similar, although they show more drastic consequences in the rcp8.5 model. Stevia alpina, S. breviaristata and S. minor reduce their area of aptitude, while S. vaga and S. yaconensis experience an increase of said area. Except for S. minor, the species showed a major tendency to migrate from East to West, a phenomenon known as altitude shift. Stevia minor would be the more affected species in a higher gas emission scenario since it will suffer a reduction greater than 80% for its suita...

Potential and current distribution of giant anteater (Myrmecophaga tridactyla) and identification of priority areas for its conservation The giant anteater (Myrmecophaga tridactyla) is widely distributed throughout the Neotropical region, but is probably extinct from most of its range, notably in Central America and the southern limits of its distribution. The species is listed as Vulnerable on the IUCN and national Red Lists. Although historically present in all Brazilian biomes, there are no studies reviewing its distribution, nor has it been evaluated if the Brazilian federal conservation units are protecting the areas most suitable to the species. Thus, the aim of this study was to model the potential and current distribution of the giant anteater in Brazil and Brazilian biomes, to identify which predictor variables best explain the occurrence of the species at different scales. Current distribution models were used to evaluate the biomes environmental suitability (i.e. probability of presence) and a gap analyses were performed. Also, priority areas for conservation were identified. The potential distribution of the anteater was better explained on a continental scale by bioclimatic (seasonality of temperature and precipitation) and topographic (altitude) variables, while the current distribution was well predicted in both scales, by land cover variables (percentages of tree cover, silviculture, and sugarcane). The Cerrado was the biome of greater environmental suitability to the species, followed by the Amazon, the Pantanal, the Atlantic Forest and the Caatinga. No recent records were obtained for the Pampas. Conservation units protect less than 10% of the current distribution of the giant anteater in the Cerrado and Pantanal. Priority areas for the species include a central corridor in the Cerrado, much of the Pantanal and ecotones. The results obtained in this study helped to fill knowledge gaps on the distribution of the giant anteater in Brazil, supporting actions for its conservation.
