  Procambarus clarkii is an important invasive freshwater species whose ecological plasticity allows for its establishment in different kinds of environments; such plasticity is also reflected in its diet with two main ...

• A conceptual framework for range-expanding species that track human-induced environmental change

  For many species, human-induced environmental changes are important indirect drivers of range expansion into new regions. We argue that it is important to distinguish the range dynamics of such species from those that occur ...

• The global pet trade in amphibians: species traits, taxonomic bias, and future directions 

  Mohanty, N.P.; Measey, J. (2019)
