Our line of research emerges to the question the causes that generate and maintain biological diversity in environments subject to changes in local and global because of natural effects and human action that either gradual or sudden, catastrophic way, well stochastic processes or programmed by man, to determine the variation in the environment. We question in what measure the organisms are adapted to such changes; What are organisms, Habitat, range and what are the evolutionary lines threatened, if there is a way to prevent their extinction, if there is some order of interest from different taxa man and what is the order of priority for conservation of the different storylines, threatened organisms, their habitats and landscapes where fits them.
Is the value to the average natural of form such as could assess is them resources artistic and cultural taking in has that is heritage common to all the planet which has the uniqueness universal of develop life and not as mere source of obtaining of resources exploitable by the man. We understand that such exploitation of resources is a basic need for mankind, but we cannot assess the natural environment from the economic perspective, but following criteria similar to those used to assess any artistic or cultural expression, taking into account the uniqueness of the evolutionary phenomenon.
The populations of lesser Kestrel (Falco naumanni) in the Iberian Peninsula suffered a major decline in decades. Currently, two highlights of his evolutionary biology have drawn our attention since their knowledge is essential to better understand the current dynamics of its population numbers. On the one hand their genetic diversity: the genetic variability of individuals in relation to different vital parameters related to the biological effectiveness, and population genetic variability in relation to dispersion, demography and the isolation of colonies. From a perspective more behavioral and population ecology have addressed the importance of public information on the dynamics of the formation of the colonies, the signals that determine the attraction to a specific colony and the evolutionary role that plays the dispersal between colonies from the perspective of the biological effectiveness.

Yet considering sustainable development as a useful tool that combines economic, social and environmental interests, we believe that sustainable development can not be used as a universal tool that all conservation actions must be based. This is because to reach support, economic, environmental and social interests should coincide in similar time scales but this does not happen frequently making commitment to uncertain if not impossible in the medium and long term. Thus, we propose forms of conservation not subject to unstable balances such as those based on strictly economic criteria.
Mioscirtus wagneri is a Grasshopper dependent on salted lands influenced by plant Suaeda vera on which it depends. Along with other species of Orthoptera is emblematic species of the few Mediterranean hypersaline environments and we are using it as a study model for the evolutionary importance of the dispersion and fragmentation of the habitat from a genetic and population point of view. As with other species of these environments (e.g. cricket silver rattlesnake (Gryllodinus kerkennensis)) his presence is synonymous with a not too unfortunate management of the environment closest to these gaps and the Iberian successfully.

As a framework for our research, we started by empirical studies that show the advantages of genetic diversity at different levels of biological organization, for example, individuals, social groups, species and communities.
Ditches flooded in Montes de Toledo, place of reproduction of several species of amphibians, such as the speckled toad (Pelodytes punctatus). This type of media aquatic temporary and of little entity are of great importance for the survival of many species to scale regional. One of our lines of research focuses on better understanding of the effects of fragmentation of habitat in the patterns of diversity and multiple species codistribuidas genetic structure.

Any habitat on our planet is subjected to changes continuous and stochastic, sometimes catastrophic occurred by phenomena natural or intervention human. These changes can be dramatic at the population level or even species. Natural selection and other causes contribute to impaired populations and genetic variability. These changes can be dramatic for many individuals that perish and can represent a high stress for the survivors. Thus, environmental changes can cause harmful effects on the natural populations. Even more, these changes can have consequences on the distribution, probability of extinction local, and about the diversity phenotypic and genotypic of them populations survivors. Our goal is to reveal these effects and mechanisms at the level of organisms and populations that allow to restore or maintain the biological variation. The documentation of aspects of ecology, distribution and demography and its possible relationship with the maintenance of critical levels of variability and gene flow in natural populations is essential for all this.
To include in the group the old sub-line of genetics of wild species, we incorporate your work. Develop and apply markers molecular for studying the structure genetic of populations wild. Population genetics studies how genetic variation is distributed among species, populations and individuals, whereas the way in which evolutionary forces of mutation, selection, genetic drift and migration affect the distribution of genetic variation. We studied genetic aspects that apply in the knowledge and management of wild animals. Such approaches include forensic techniques; studies phylogenetic, of populations and of establishment of relations family; identification of individuals and species and characterization of introgression.
The surroundings of the hypersaline lagoons are unique environments, refuge of influence salinity-resistant or halophilic species. These areas of high ecological and evolutionary value, are of great natural value species unique, rare, endemic or endangered. Due to the isolation and fragmentation of these habitats some taxonomic groups that inhabit them are models suitable for the study of populations from the point of view of evolutionary biology and conservation.
