In animals that are kept in temperate latitudes and that are seasonal in their breeding activity, nutritional and photoperiodic signals operate in harmony to time the activation of the gonadotrophin-releasing hormone (GnRH) pulse generator in the brain and trigger puberty. These signals ensure that within the constraints imposed by the circannual changes in the environment, body size and time o...

In animal behaviour, there is a dichotomy between innate behaviours (e.g., temperament or personality traits) versus those behaviours shaped by learning. Innate personality traits are supposedly less evident in animals when confounded by learning acquired with experience through time. Learning might play a key role in the development and adoption of successful anti-predator strategies, and the ...

El objetivo principal de esta tesis doctoral ha sido evaluar el efecto la variación ambiental sobre reproducción diferentes poblaciones ciervo (Cervus elaphus) y corzo (Capreolus capreolus) situadas en límite su área distribución, como son región Mediterránea Alpina. Estas marginales pueden aportar una información muy valiosa contexto actual cambio climático ya que ayudar a predecir futuros cam...
