Rapid identification of invasive non-native species aids conservation efforts, particularly in threatened and vulnerable species. However, this can be extremely challenging for morphologically similar non-native and native species, especially for those with cryptic coloration and small home ranges. This holds for non-native green iguanas (NNGI; Iguana iguana ), which threaten insular Iguana populations through displacement acr...

The frequency of polyploidy increases with latitude in the Northern Hemisphere, especially in deglaciated, recently colonized areas. The cause or causes of this pattern are largely unknown, but a greater genetic diversity of individual polyploid plants due to a doubled genome and/or a hybrid origin is seen as a likely factor underlying selective advantages related to life in extreme climates and/or colonization ability. A hist...
