Resumen
[ES] Para entender la relación entre las variables ambientales y la respuesta del crecimiento de los individuos se han empleado marcas de crecimiento en el cemento del primer molar de 103 cérvidos en Sierra de Andújar, estableciendo, mediante modelos lineales mixtos, la influencia del clima y la densidad de población sobre tasas de crecimiento en dos localidades. Con respecto al clima, se han observado diferencias en condiciones ambientales entre ambas localidades. Se han observado tendencias de crecimiento constantes para hembras y machos de Lugar Nuevo. En cuanto a machos y hembras de Selladores Contadero se pudieron observar ciclos de crecimiento más pronunciados, como consecuencia de las variaciones climáticas. El crecimiento en machos va a estar condicionado por temperatura y precipitación, mientras que en hembras sólo hay influencia de la temperatura. El ajuste de los modelos a los datos experimentales permitiría emplearlos para gestionar las densidades de población bajo diferentes condiciones climáticas.
[EN] In order to understand the relationship between environmental variables and growth response of cervids, we used the first molar growth marks of 103 cervids in two locations of Sierra de Andújar, establishing, by means of mixed linear models, the influence of climate and population density on growth rates. Regarding climate, differences in environmental conditions between both locations have been observed. In terms of growth trends, for females and males from Lugar Nuevo, mostly constant trends in growth were observed over time. Concerning the males and females from Selladores Contadero, more pronounced growth cycles were observed as a result of climatic variations. The growth in males is conditioned by temperature and precipitation, while in females only the influence of temperature was found, depending also on the location. Finally, the adjustment of the models to the experimental data would allow us to manage the densities of the population under varying climatic conditions.
