The integration and synthesis of the data in different areas of science is drastically slowed and hindered by a lack of standards and networking programmes. Long‐term studies of individually marked animals are not an exception. These studies are especially important as instrumental for understanding evolutionary and ecological processes in the wild. Furthermore, their number and global distribution provides a unique opportunity to assess the generality of patterns and to address broad‐scale global issues (e.g. climate change). To solve data integration issues and enable a new scale of ecological and evolutionary research based on long‐term studies of birds, we have created the SPI‐Birds Network and Database (www.spibirds.org)—a large‐scale initiative that connects data from, and researchers working on, studies of wild populations of individually recognizable (usually ringed) birds. Within year and a half since the establishment, SPI‐Birds has recruited over 120 members, and currentl...

Este trabalho teve como objectivo determinar uma metodologia de avaliação dos efeitos de certos pesticidas específicos utilizados em luta integrada sobre os predadores afidífagos da família Coccinellidae. A escolha dos predadores obedeceu a critérios de evolução ...

Nos últimos anos, tem vindo a ser dada a maior importância aos estudos dos efeitos secundários dos pesticidas aplicados em agricultura. Empregados com um fim imediato-a eliminação das pragas nocivas as culturas-a verdade é que, para além dos efeitos letais ...

Mestrado em Biologia Aplicada - Ecologia, Biodiversidade e Gestão de EcossistemasSpecies reintroduction is increasingly becoming an important part of species recovery programs and habitat restoration initiatives worldwide. Roe deer (Capreolus capreolus) have been reintroduced to Portugal in the past, but the a priori identification of suitable sites for reintroduction can greatly improve the success of such programmes. This study is focused on the first phase of the reintroduction process - the viability phase -, where our study area (Freita, Arada and Montemuro mountains) was characterized and evaluated in terms of suitability to implement the reintroduction process and define reintroduction nuclei in central Portugal. For this, we have used empirical models and expert knowledge (Analytical Hierarchy Process coupled with GIS), and we have identified three reintroduction nuclei suitable for roe deer occurrence and future natural expansion (Manuscript I). The variables used in the mo...
