Climatic constraints and the distribution of Patagonian mice

Abstract: We generated potential distribution models for 14 sigmodontine rodent species that inhabit the Andean–Patagonian forest region and adjacent areas, and retrieved the main climatic variables responsible for these models. Our main objective was to compare these climatic variables and the distribution patterns generated for each species, and explore the effects of the physical environment in shaping the composition of rodent communities in the area. We retrieved a total of 1,215 records of species presence from 58… Show more

“…We then excluded bio08, bio09, bio18 and bio19, which combine temperature and precipitation information in one layer. These variables show spatial discontinuities that are presumably not existent in the environmental conditions and should therefore be interpreted as artefacts (Escobar et al 2014 ; Ruiz Barlett et al 2019 ). With a threshold of 0.3 for the dissimilarity, which is the most commonly applied threshold to reduce collinearity in the environmental data sets (Dormann et al 2013 ), we built groups of interrelated variables.…”

“…We then excluded bio08, bio09, bio18, and bio19, which combine temperature and precipitation information in one layer. They show weird spatial discontinuities that are presumably not existent in the environmental conditions and should therefore be interpreted as anomalies (Ruiz Barlett et al, 2019 ).…”

“…Además, se desempeña bien con tamaños de muestra pequeños (Wisz et al 2008), incorpora efectos de interacción de variables ambientales y es un algoritmo determinista, lo que significa que los resultados siempre convergen en una distribución de probabilidad óptima única (Phillips et al 2006). Los modelos MaxEnt se generaron para cada especie utilizando un 25% de datos de prueba, corridas aleatorias sin correlación alguna, 1000 iteraciones, 10 repeticiones, 10000 puntos de fondo y la opción acumulativa como formato de salida (Phillips and Dudik 2008;Merow et al 2013;Ruiz Barlett et al 2019).…”

“…Dentro de los modelos candidatos se seleccionaron según el valor mínimo para el AICc y promediados de acuerdo con sus correspondientes ponderaciones de Akaike (Bouchet and Meeuwig 2015). Los mapas de la especie se generaron utilizando los valores medios proporcionados por MaxEnt (Martin 2010;Schiaffini et al 2013;Ruiz Barlett et al 2019). Elegimos los valores de la mediana porque representan una caracterización estadística más robusta que la media, en particular para la función de densidad de probabilidad de una población biológica, que tiene naturalmente un límite inferior igual a cero (Feller 1967).…”
