“…Approaches enabling a representative sampling of genome‐wide genetic variability allow a more powerful and refined phylogeographical inference, overcoming the limitations of mtDNA markers (Cutter & Payseur, 2013; Delsuc et al, 2005; McCormack et al, 2013). Such approaches have provided information on taxon diversification on islands (Charles et al, 2018; Jensen et al, 2021; Manthey et al, 2020; Papadopoulou & Knowles, 2017), and island population histories (Blumenfeld et al, 2021; Martin et al, 2021; Rosenthal et al, 2021; Sherpa et al, 2019), but very few studies have attempted to disentangle the role of natural versus human‐aided dispersal (McDevitt et al, 2022).…”

AimThe Mediterranean Basin is a global biodiversity hotspot and has one of the longest histories of human–biota interactions. Islands host a large fraction of Mediterranean diversity and endemism, but the relative importance of natural versus human‐mediated colonisation processes in shaping the distribution and genetic structure of Mediterranean island fauna remains poorly understood. Here, we combine population genomics, demographic models and palaeoshoreline reconstructions to establish the island‐colonisation dynamics of wall lizards in Mediterranean archipelagos.LocationFour Mediterranean archipelagos in Italy and Croatia.TaxonThe wall lizard Podarcis siculus.MethodsWe used ddRAD sequencing to genotype 140 lizards from 23 island and mainland populations. Analyses of admixture and site frequency spectra were used to reconstruct population structure, demographic history and variation of gene flow through time. Genomic results were integrated with palaeogeographical reconstructions and were compared to archaeological evidence of human presence on these islands.ResultsAlthough many island populations of this species are assumed to be non‐native, we find that many islands were colonised long before any known human settlements (230,000–12,000 years ago). This natural colonisation most likely occurred through land bridges during glacial marine regression or by over‐sea rafting. On the other hand, islands distant from the continent were often colonised recently, and some of the estimated island colonisation times match historical records of human arrival. We also determine that long‐established island populations generally show lower genetic diversity compared to proximate mainland populations, contrary to recently colonised islands that must have experienced higher rates of post‐colonisation gene flow.Main ConclusionOur integrated approach provides us with the power to accurately quantify the origin, timing and mode of island colonisation. This framework helps to clarify the biogeographical and evolutionary history of island populations, with important implications for conservation and management of island biodiversity.

“…Polar and boreal regions were excluded from the investigation because of limited data availability. The four traits of interest, generation time, longevity, temperature range, and trophic level, have been systematically reported as key traits for invasive success (Pimm, 1991; Crowder and Snyder, 2010; Zerebecki and Sorte, 2011; Deacon and Magurran, 2016; Rosenthal et al ., 2021).…”

“…To illustrate the scientific significance and accessibility of ITOFF, we investigate differences in life-history traits often predicted to facilitate species invasions among invasive, critically endangered, endangered, and impacted species for temperate, subtropical, and tropical regions. We focus on four traits shown to be critical to invasive success (Pimm, 1991; Crowder and Snyder, 2010; Zerebecki and Sorte, 2011; Deacon and Magurran, 2016; Rosenthal et al ., 2021). Namely, generation time, trophic level, longevity, and temperature range.…”

“…Namely, generation time, trophic level, longevity, and temperature range. We expected invasive species to have shorter generation times and reduced longevity to facilitate fast population growth (Pimm, 1991) and rapid adaptation (Rosenthal et al ., 2021). Further, we expected invasive species to have wider temperature ranges, as this increases the likelihood of survival across a range of environments (Zerebecki and Sorte, 2011).…”

AIMSpecies invasions are a major driver of global biodiversity loss, but only a minority of invasions are successful. Evidence suggests that invasive success is linked to life-history traits. Yet, data on invasive success and species’ traits remain fragmented across multiple sources. Here we present the Invasive Traits of Freshwater Fish (ITOFF) database, an interdisciplinary framework that integrates multiple datasets to elucidate the role of life-history traits in shaping invasive success. ITOFF allows seamless access to invasive species data and fosters collaborative actions through knowledge sharing. ITOFF is supported by an innovative web-application that makes complex relationships between invasive and native species accessible to a broad audience. The scientific contribution of ITOFF is illustrated by examining the role of life-history traits and phylogeny in invasion success.LOCATIONGlobal.METHODSGeneralized linear models were used to test the contribution of generation time, trophic level, longevity, and temperature range to invasive success. Through divisive cluster analysis we investigate the role of multiple traits in determining invasive success. Finally, we construct phylogenetic trees to investigate the role of evolutionary history in the invasion process.RESULTSITOFF unifies data for 1917 freshwater fish species representative of invasive species, those species they endanger, and species impacted by invasives but not considered endangered. Invasive species are generally characterized by greater temperature ranges, but are indistinguishable from impacted, endangered, and critically endangered species for the remaining life-history traits. Further, we show that invasive species are generally not distinct from impacted or endangered species when considering multiple traits or phylogeny.MAIN CONCLUSIONSITOFF provides an accessible platform for the improved forecasting of species invasions. ITOFF data shows that classical predictions of life-history traits determining invasive success do not hold amongst freshwater fish species. Forecasting of invasive species must therefore shift towards a wholistic approach encompassing the species and the environment.

“…We examined 292 adult Trinidadian guppies ( P . reticulata ) from 12 populations in their native range on Trinidad and 185 adult guppies from three populations in O'ahu, Hawaii where they were introduced approximately 100 years ago (Brock, 1960; Rosenthal et al, 2021) (Table ; see Santi et al, 2021). These localities include a natural asphalt lake (Pitch Lake), several oil‐polluted sites, and unpolluted ponds, ditches, and streams.…”

Resource competition explains rare cannibalism in the wild in livebearing fishes

Cannibalism, the act of preying on and consuming a conspecific, is taxonomically widespread, and putatively important in the wild, particularly in teleost fishes. Nonetheless, most studies of cannibalism in fishes have been performed in the laboratory. Here, we test four predictions for the evolution of cannibalism by conducting one of the largest assessments of cannibalism in the wild to date coupled with a mesocosm experiment. Focusing on mosquitofishes and guppies, we examined 17 species (11,946 individuals) across 189 populations in the wild, spanning both native and invasive ranges and including disparate types of habitats. We found cannibalism to be quite rare in the wild: most populations and species showed no evidence of cannibalism, and the prevalence of cannibalism was typically less than 5% within populations when it occurred. Most victims were juveniles (94%; only half of these appeared to have been newborn offspring), with the remaining 6% of victims being adult males. Females exhibited more cannibalism than males, but this was only partially explained by their larger body size, suggesting greater energetic requirements of reproduction likely play a role as well. We found no evidence that dispersal‐limited environments had a lower prevalence of cannibalism, but prevalence was greater in populations with higher conspecific densities, suggesting that more intense resource competition drives cannibalistic behavior. Supporting this conclusion, our mesocosm experiment revealed that cannibalism prevalence increased with higher conspecific density and lower resource levels but was not associated with juvenile density or strongly influenced by predation risk. We suggest that cannibalism in livebearing fishes is rare in the wild because preying on conspecifics is energetically costly and only becomes worth the effort when competition for other food is intense. Due to the artificially reduced cost of capturing conspecifics within confined spaces, cannibalism in captive settings can be much more frequent.
