Los dispositivos de localización que incorporan tecnologías Sistema Posicionamiento Global (GPS) y acelerómetro (ACC), han supuesto un avance muy importante en el estudio la ecología animal. Utilizando datos 53 avutardas hubaras (Chlamydotis undulata fuertaventurae) marcadas con emisores GSM/GPRS durante periodo 2017-2022 las islas Lanzarote, Fuerteventura La Graciosa, describimos cómo es posib...
BACKGROUND The "good genes" theory of sexual selection postulates that females choose mates that will improve their offspring's fitness through the inheritance of paternal genes. In spite of the attention that this hypothesis has given rise to, the empirical evidence remains sparse, mostly because of the difficulties of controlling for the many environmental factors that may covary with both th...
Species Distribution Models predict abundance and its temporal variation in a steppe bird population
Habitat Suitability Index (HSI) derived from Species Distribution Model (SDM) has been used to infer or predict local demographic properties such as abundance for many species. Across species studied, HSI either presented a poor predictor of potential rather than realized abundance. The main explanation the lack relationship between and is that varies in time due various ecological processes ar...
Although density-dependent processes and their impacts on population dynamics are key issues in ecology conservation biology, empirical evidence of density-dependence remains scarce for species or populations with low densities, scattered distributions, especially managed where densities may vary as a result extrinsic factors (such harvesting releases). Here, we explore the presence reinforced ...
Population reinforcement, through translocations of individuals, aims to restore populations threatened species. The increase in population size or geographic distribution is often used as positive facts when assessing the recovery a species, making abundance monitoring major criterion. Based on 8-year reinforced North African Houbara bustard (Chlamydotis undulata undulata), over an area 50 170...
Translocation of captive-bred individuals to reinforce wild populations may be an important conservation approach for some species, but can detrimental when employed boost exploited populations, particularly where repeated long-term reinforcement aims compensate unregulated offtake. We review evidence that captive breeding alters multiple physiological, life-history and temperamental traits thr...
