A scientific team led by the Doñana Biological Station - CSIC reviews historical documentation to estimate the distribution of the wolf in Spain in the 19th century
The results show that the wolf could be found in all the provinces and its presence was less frequent in flatter areas, more suitable for agriculture and with higher population density

A study by Miguel Clavero, a researcher at the Doñana Biological Station – CSIC, reconstructs the history of the first introductions of pike, common carp, tench and Italian crayfish into Spain.

Interdisciplinary studies allow to introduce a long-term perspective on the magnitude and rhythm of changes in ecosystems, including biological invasions.

The red swamp crayfish (Procambarus clarkii), native to the southern United States and north-eastern Mexico, is currently the most widely distributed crayfish globally, as well as one of the invasive species with most devastating impacts on freshwater ecosystems. Reconstructing the introduction routes of invasive species and identifying the motivations that have led to those movements is necessary to accurately reduce the likelihood of further introductions. In this study, the temporal...

Historical species records offer an excellent opportunity to test the predictive ability of range forecasts under climate change, but researchers often consider that historical records are scarce and unreliable, besides the datasets collected by renowned naturalists. This study demonstrates the relevance of biodiversity records generated through citizen science initiatives generated outside the natural sciences academia.

Anciently introduced species can be confounded with native species because introduction pre-dates the first species inventories or because of the loss of the collective memory of the introductions. Here, an integrative, multidisciplinary approach was followed to solve the status of a cryptogenic species, proposing that building on evidence from multiple disciplines can produce robust and clarifying insights.
