Data from: Coordinated species importation policies are needed to reduce serious invasions globally: the case of alien bumblebees in South America

The global trade of species promotes diverse human activities but also facilitates the introduction of potentially invasive species into new environments. As species ignore national boundaries, unilateral national decisions concerning species trade set the stage for transnational species invasion with significant conservation, economic and political consequences. The need for a coordinated approach to species importation policies is demonstrated by the introduction of two bumblebee species into Chile for crop pollination, despite Argentina banning commercial importation...

Data from: Temporal genetic variance and propagule-driven genetic structure characterize naturalized rainbow trout (Oncorhynchus mykiss) from a Patagonian lake impacted by trout farming

Javiera Nidia Benavente, Lisa Wishard Seeb, James Edward Seeb, Ivan Arismendi, Cristián Esteban Hernández, Gonzalo Gajardo, Ricardo Galleguillos, Maria Ignacia Cádiz, Selim Seman Musleh & Daniel Gomez-Uchida
Knowledge about the genetic underpinnings of invasions—a theme addressed by invasion genetics as a discipline—is still scarce amid well documented ecological impacts of non-native species on ecosystems of Patagonia in South America. One of the most invasive species in Patagonia’s freshwater systems and elsewhere is rainbow trout (Oncorhynchus mykiss). The species was introduced in Chile during the early twentieth century for stocking and promoting recreational fishing and, during the late twentieth century, for farming purposes...

Data from: Contrasting genetic metrics and patterns among naturalized rainbow trout (Oncorhynchus mykiss) in two Patagonian lakes differentially impacted by trout aquaculture

Cristian B. Canales-Aguirre, Lisa W. Seeb, James E. Seeb, Maria I. Cadiz, Selim S. Musleh, Ivan Arismendi, Gonzalo Gajardo, Ricardo Galleguillos & Daniel Gomez-Uchida
Different pathways of propagation and dispersal of non-native species into new environments may have contrasting demographic and genetic impacts on established populations. Repeated introductions of rainbow trout (Oncorhynchus mykiss) to Chile in South America, initially through stocking and later through aquaculture escapes, provide a unique setting to contrast these two pathways. Using a panel of single nucleotide polymorphisms, we found contrasting genetic metrics and patterns among naturalized trout in Lake Llanquihue, Chile’s largest producer of...

Neutral and adaptive loci reveal fine-scale population structure in Eleginops maclovinus from North Patagonia

Cristian B. Canales-Aguirre, Wesley A. Larson, Garret J. McKinney, C. Eliza Claure, J. Dellis Rocha, Santiago G. Ceballos, Maria I. Cádiz, José M. Yáñez & Daniel Gómez-Uchida
Patagonia is an understudied area, especially when it comes to population genomic studies with relevance to fishery management. However, the dynamic and heterogeneous landscape in this area can harbor important but cryptic genetic population structure. Once such information is revealed, it can be integrated into the management of infrequently investigated species. Eleginops maclovinus is a protandrous hermaphrodite species with economic importance for local communities that is currently managed as a single genetic unit. In this...

Data from: Winning the invasion roulette: escapes from fish farms increase admixture and facilitate establishment of non-native rainbow trout

Sofia Consuegra, Nia Phillips, Gonzalo Gajardo & Carlos Garcia De Leaniz
Aquaculture is a major source of invasive aquatic species, despite the fact that cultured organisms often have low genetic diversity and tend to be maladapted to survive in the wild. Yet, to what extent aquaculture escapees become established by means of high propagule pressure and multiple origins is not clear. We analysed the genetic diversity of 15 established populations and 4 farmed stocks of non-native rainbow trout in Chile, a species first introduced for recreational...

Historical warming consistently decreased size, dispersal and speciation rate of fish

Jorge Avaria-Llautureo, Chris Venditti, Marcelo Rivadeneira, Oscar Inostroza-Michael, Reinaldo Rivera, Cristián Hernández & Cristian Canales-Aguirre
There is ongoing debate as to whether fish body size will decrease with global warming and how these changes may impact dispersal ability and speciation rate. Theory predicts that, under warmer temperatures, fish grow to a smaller size, undergo a reduction in dispersal ability and increase speciation rates. However, evaluations of such predictions are hampered owing to the lack of empirical data spanning both wide temporal and geographical scales. Here, using phylogenetic methods, we show...
