Urban landscape selection by Eurasian collared dove (Streptopelia decaocto) in eastern Spain
The Eurasian collared dove (Streptopelia decaocto) is an invader species, and its distribution is continuously on the increase. Today its expansion has spread to the American continent. In this study we describe the effects of the urban environment on the Eurasian collared dove in eastern Spain. The abundance and presence of this dove were analyzed in 46 localities using counting points. Overall, 220-point counts were surveyed between autumn 2015 and late-winter 2016. A hierarchical partitioning analysis was used to identify explanatory variables of different types such as resources, climate and urban structure, and human presence, which may influence the presence and abundance of this species. In the case of presence, the number of town inhabitants, parks, mean minimum temperature, exotic vegetation and schools had a positive association, while pedestrian number and restaurants had a negative association. Abundance was positively related to native vegetation, exotic vegetation, and water, while urban area was negatively associated with it. Exotic vegetation was the only variable that has a positive relation to presence and abundance. These results can help to predict the use of urban habitats in potential localities for its invasion.

La tórtola turca (Streptopelia decaocto) es una especie invasora y su ámbito de distribución aumenta continuamente. Hoy en día, su expansión incluye el continente americano. En este estudio se describen los efectos que el ambiente urbano tiene sobre la tórtola turca en el este de España. Se muestrearon 46 localidades mediante puntos de conteo. La abundancia de la tórtola turca fue evaluada en 220 puntos de conteo entre otoño de 2015 y finales de invierno 2016. Se utilizó el análisis de partición jerárquica para identificar variables explicativas como recursos, clima y estructura urbana, y presencia humana, que pueden influir en su presencia y abundancia. En el caso de la presencia de la especie, el número de habitantes de la ciudad, parques, temperatura media, vegetación exótica y colegios tuvieron una asociación positiva, mientras que el número de peatones y los restaurantes estuvieron negativamente asociados. La abundancia estuvo positivamente relacionada con la vegetación nativa, vegetación exótica y el agua, mientras que la zona urbana estuvo negativamente asociada. Estos resultados pueden predecir el uso de hábitats urbanos en localidades potenciales para su invasión.
