One century of crayfish 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 citizen science to understand and predict climate-driven trout decline

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.

The native crayfish is a non-native species

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.
