A fundamental constituent of a biodiversity observation network is the technological infrastructure that underpins it. The European Biodiversity Network project (EU BON) has been working with and improving upon pre-existing tools for data mobilization, sharing and description. This paper provides conceptual and practical advice for the use of these tools.

Alien species can exert negative environmental and socio-economic impacts. Often it is not clear which of the numerous alien species are most important in terms of damage, and therefore, impact scoring systems have been developed to allow a comparison and thus prioritization of species. Here, the Generic Impact Scoring System (GISS) is presented, which relies on published evidence of environmental and socio-economic impact of alien species.

Immigration and local recruitment play a central role in determining the growth rate of breeding populations. Unravelling these processes in newly-established populations is of great importance to increase understanding of how species change their distributions in response to global change. In this study, these processes were analyzed through the monitoring of a glossy ibis population in Doñana.

Since the creation of the LTER-Spain network in 2008, the different nodes have implemented long-term environmental programs. This monograph shows the progress in the implementation of long-term ecological research in sites that are part of the Spanish network.

Wildlife inhabiting human-dominated landscapes is at risk of pathogen spill-over from domestic species. With the aim of gaining knowledge in the dynamics of viral infections in Iberian wolves living in anthropized landscapes of northern Spain, samples of wolves were analysed by serology and polymerase chain reactionfor exposure to four pathogenic canine viruses. Results suggest that rural dogs might be the origin of canine parvovirus-2 infecting wolves.
