Ecological patterns and processes
This line of research aims to describe and understand ecological and ecophysiological patterns and processes that determine the distribution and abundance of organisms on different spatial and temporal scales. In the context of population ecology, projects investigate aspects of how populations are structured, how changes in structural parameters occur over time and what factors determine these changes, whether they are intrinsic (behavioural, physiological or genetic), related to environmental conditions, or linked to interactions between organisms.
Additionally, by applying detailed analyses of population interactions, projects aim to gain a better understanding of the organisation and dynamics of trophic webs within spatial and temporal contexts. Biological communities are assessed in terms of structural aspects such as abundance, species richness and composition, and the relationship between these aspects are investigated including the effect of varying conditions of the physical environment, both in terrestrial and aquatic environments. Changes in community structure over time are assessed through long-term studies. On a broader spatial and temporal scale, changes in the landscape are investogated in an evolutionary context, or in the context of anthropogenic modifications, in order to understanding the structure, composition, processes (or functions) and dynamics of landscapes.

Systematics, biogeography and genetic diversity
This line of research aims to describe and understand evolutionary patterns and processes that determine the generation and maintenance of biological diversity over generations. Specifically, it aims to contribute to the description of new taxa, as well as presenting new proposals for classifying organisms at different hierarchical levels, in addition to testing evolutionary hypotheses about biological diversification processes involving populations, species and groups of species. To this end, it considers the characterisation of the genetic variability of natural populations through genotypic and phenotypic studies (microevolution) and the effect of evolutionary mechanisms over time (macroevolution).
