Especie clave como recurso cinegético y por sus impactos ambientales y sociales. Todos tenemos puesto el ojo en el jabalí. Junto con el ciervo, es la pieza de caza mayor por excelencia en Extremadura. En las últimas temporadas, a excepción de la temporada 2020/2021 debido a las restricciones por la pandemia, se han venido cazando más de 20,000 jaba...
Birds use songs and calls as communicative signals. The production of bird vocalizations depends on stimuli that prompt or deter communications. The quartzite scree slopes (pedrizas) in the Mediterranean forests of southwestern Spain might potentially engender conflict situation for bird communication. These open areas entail enhanced sound transmi...
La Caza ha sido una actividad consustancial a la especie humana desde sus orígenes, marcando su biología y evolución. En la actualidad, nuevas tendencias de opinión, la consideran cruel e innecesaria, convirtiéndola en objeto de controversia, constituyendo un claro exponente del conflicto latente entre una España rural y otra urbanita. En este cont...
Wild boar (Sus scrofa) populations are increasing worldwide, leading to health, economic and conservation issues. Assessing genetic structure and diversity can aid in the effective monitoring and management of wild boar populations. Processes related to sexual selection and behavioral differences between sexes support the importance of considering...
Hunting is one of the main uses associated with land which, in the current context, has a strong economic significance for rural areas. This work generates knowledge that can be useful for designing strategies that favour the economic dynamisation of rural areas, in a context of population loss and scarce economic diversification. In this sense and...
Human disturbance has been shown to provoke physiological and behavioral responses in birds, so nature-based tourism might reduce bird abundance and diversity. The negative consequences of human disturbance might be expected to be maximized during eventual massive events in highly protected areas such as national parks. In this study, the consequen...
Las molestias por parte de la actividad humana pueden provocar respuestas fisiológicas y comportamentales en las aves, por lo que el turismo de naturaleza podría disminuir su presencia y actividad. Es esperable que las consecuencias negativas de estas molestias se maximicen durante el desarrollo de eventos masivos realizados en áreas altamente prot...
Recreational hunting can have positive consequences on biodiversity conservation, but in many countries the number of hunters is declining. This downward trend threatens the sustainability of an important human activity that can be used as a tool for wildlife management and biodiversity conservation. On the other hand, in developed countries there...
Hunting has played a relevant role throughout human evolution. At present, hunting is considered a recreational and economic activity, and is rarely necessary for survival.
In this context, in a society increasingly committed to conservation, hunting must be managed, not only to ensure its sustainability, but also to conserve and promote
biodiversi...

¿Las aves utilizan las pendientes pedregosas (pedrizas) de cuarcita para fomentar la transmisión del sonido en los bosques mediterráneos?
Las aves generan vocalizaciones (melodías y llamadas) para comunicarse. Como la comunicación acústica puede verse obstaculizada por ciertas características del hábitat, es posible que las aves se valgan de difer...
ABSTRACT:
Hunting has been an activity inherent to the human species since its origins, marking its biology and evolution. Currently, new trends of opinion consider it cruel and unnecessary, making it an object of controversy, constituting a clear exponent of the latent conflict between a rural Spain and another urban one. In this context, it is ne...

Burrows play an essential role for the European wild rabbit. They provide shelter,
a safe breeding place and protection against climatic extremes. However, little is
known about burrow structure and the environmental factors influencing it. In this
work we analyse the structure of rabbit burrow tunnels in southwestern Spain and
search for structura...
Aims To describe the present pattern of the spread of the Collared Dove in one of the few areas in Europe where the process is still active, in the light of the hypothesis of general expansion in Europe. Methods Information was obtained from field data collected in 1996–97 and from responses by local observers to a questionnaire. We recorded data o...

sedentaria y otra invernan...
La caza menor siempre ha estado ligada a la agricultura, dependiendo en buena parte de los recursos que ésta
genera. En Andalucía, la mayor parte de los terrenos dedicados a caza menor corresponden a zonas agrícolas,
generalmente dedicadas al cultivo extensivo de secano. La evolución reciente de la agricultura, bajo la influencia
de la PAC, ha teni...

RESUMEN
La Tórtola Común o Europea Streptopelia turtur, es una pequeña colúmbida migratoria, que se reproduce principalmente en Europa y pasa el invierno en el África subsahariana, constituyendo un recurso cinegético tradicional en la mayor parte de su área de distribución.
En los últimos años hemos sido testigos de una paulatina, pero marcada dism...
Resumen
Una de las medidas mas empleada en la actualidad para favorecer la recuperación del Conejo de monte (Oryctolagus cuniculus) es, si duda, la repoblación. Este método, si bien incrementa el número de conejos de un coto en un corto período de tiempo, también supone un alto coste económico y un elevado esfuerzo de medios que, en muchos casos, n...
The spread of the Collared Dove Streptopelia decaocto in Europe: colonization patterns in the west of the Iberian Peninsula: The pattern and timing of spread are examined, particularly in Extremadura, and theories on speed and extent of spread and possible competition with related species are discussed. be used for research, teaching and private st...
La Tórtola cada vez escasea más en la Península Ibérica, pero sin embargo, en Marruecos sus efectivos aumentaron. ¿Significa esto, como interpretan algunos, que esta viajera ha modificado su comportamiento y prefiere quedarse allí? o, por el contrario, ¿se trata de un cambio real en el status de las distintas poblaciones reproductoras motivado por...
Most evergreen oak forests growing in the flat areas of the southwestern Iberian Peninsula have been gradually transformed into a unique kind of pastoral woodland, the Spanish dehesas and Portuguese montados, by means of an agroforestry use. The opening of dehesas by clearing and ploughing closed forest to obtain savannah-like landscapes with a den...
Given the decline of the Common Turtle Dove (Streptopelia turtur), the hunting pressure exerted on the species in Extremadura is assessed. Data from 113 hunts developed throughout the region during the 1999 closed season are analyzed. The results are compared with others from the 1996 and 1997 seasons. Excessive hunting pressure is evidenced as the...
La utilización del alimento como atrayente o reclamo de tórtolas y otras aves es una práctica de gestión reciente y actualmente muy extendida en España, a pesar de estar prohibida por la legislación vigente. En el presente trabajo se analiza la utilización de dichos reclamos y su efecto sobre la Tórtola. Para ello se realizó el seguimiento completo...
SUMMARY
We have studied the winter distribution of the woodcock in Extremadura
(eastern Spain). We analyzed the distribution of this species according to habitat type, altitude and latitude. It seems to be distributed throughout the middle latitudes of the region, being most abundant in wooded habitats. We found no significant differences with rega...

La tórtora turca només havia estat citada a Extremadura a tres úniques localitats, sense que encara no s'hagués confirmat mai la cria. L'any 1997 es va estudiar la zona a través de la distribució de qüestionaris i la visita posterior a diferents localitats. Addicionalment es van portar a terme transectes a tota l'àrea (47 quadrícules de 35 x 35 km,...
The composition of social groups in the wild boar was observed in Doñana National Park over a one-year cycle. Mean group size was 3.21±0.69 (mean ± SE, N = 842) individuals per group, and significant changes were observed throughout the year reaching a maximum during the birth season in spring. Ten types of groups were defined, and among them, thos...
Este es un libro (primero publicado por autores de lengua española) que trata sobre las estrategias que los seres vivos emplean para maximizar su eficacia biológica, abordadas desde los cuatro enfoques clásicos que constituyen la esencia de la Etología: las causas inmediatas o mecanismos, la ontogenia, la filogenia y la función adaptativa
Secondary sex traits involved in the courtship display of the male great bustard (Otis tarda) are analyzed in the light of condition-dependence theory. Heaviest males at the start of the mating period further gained about 30% in body mass. Both display performance and development of morphological traits involved are mainly determined by body mass....
The courtship display in male Great Bustard Otis tarda was analysed in terms of its structural meaning. The display followed a bimodal pattern of daily activity at temperatures between 15 and 21°C. It was used in both agonistic and sexual contexts. Three phases are described whose mean durations differed according to the nature, aggressive or sexua...
