Data from: Population structure and comparative phylogeography of jack species (Caranx ignobilis and C. melampygus) in the high Hawaiian Islands
Members of the family Carangidae are top-level predators and highly prized food and sport fishes. Although ecologically and economically important, little is known about the biology of numerous species in the family. This is particularly true of the jacks Caranx ignobilis and C. melampygus, which have experienced recent population reductions around the high Hawaiian Islands due to overfishing. Previous studies have documented territorial tendencies as well as cases of long-distance excursions in both species, suggesting populations may exhibit a range of structure at the genetic level. To explore this possibility, mitochondrial (mtDNA) ATPase6 and ATPase8 gene sequence variation was assessed from 91 individuals (33 C. ignobilis and 58 C. melampygus) spanning the islands of Kauai, Oahu, Molokai, Maui and Hawai'i. While a total of 20 distinct haplotypes (eight for C. ignobilis; 12 for C. melampygus) were recovered, no evidence of population structure was found for either species across the examined geographic range. However, distinct demographic patterns were identified, implying differing evolutionary histories and/or population dynamics. Additionally, ~6% of the examined C. ignobilis were C. ignobilis x C. melampygus hybrids since they harbored mitochondrial haplotypes typical of C. melampygus. These hybrids contribute to measurable gene flow between the species and may play a significant role in the evolution of the genus.

Data from: Rapid morphological change of non-native frugivores on the Hawaiian island of O'ahu
Novel ecosystems have become widespread created, in part, by the global spread of species. The non-native species in these environments can be under intense evolutionary pressures that cause rapid morphological change, which can then influence species interactions. In Hawai'i, much of the native frugivore community is extinct, replaced by non-native bird species. Here, we determined if the passerine species of the non-native frugivore community on O'ahu have morphologically diverged from their native ranges. We compared a variety of traits, all important for frugivory, between museum specimens from the species' native ranges to wild individuals from O'ahu. All four species tested exhibited significant divergence ranging in magnitude from 2.3% to 13.0% difference in at least two traits. Using a method developed from quantitative genetics, we found evidence that a mixture of non-adaptive and adaptive processes worked in concert to create the observed patterns of divergence. Our results suggest rapid morphological change is occurring and, based on the traits measured, that these changes may influence seed dispersal effectiveness. Since these species are largely responsible for seed dispersal on the island, the rapid morphological change of these species can influence the stability and maintenance of plant communities on O'ahu.
Data from: Invasion of the Hawaiian Islands by a parasite infecting imperiled stream fishes
Points of origin and pathways of spread are often poorly understood for introduced parasites that drive disease emergence in imperiled native species. Co-introduction of parasites with non-native hosts is of particular concern in remote areas like the Hawaiian Islands, where the introduced nematode Camallanus cotti has become the most prevalent parasite of at-risk native stream fishes. In this study, we evaluated the prevailing hypothesis that C. cotti entered the Hawaiian Islands with poeciliid fishes from the Americas, and spread by translocation of poeciliid hosts across the archipelago for mosquito control. We also considered the alternative hypothesis of multiple independent co-introductions with host fishes originating from Asia. We inferred conduits of introduction and spread of C. cotti across the archipelago from geographic patterns of mtDNA sequence variation and allelic variation across 11 newly developed microsatellite markers. The distribution of haplotypes suggests that C. cotti spread across the archipelago following an initial introduction on O'ahu. Approximate Bayesian Computation modeling and allelic variation also indicate that O'ahu is the most likely location of introduction, from which C. cotti dispersed to Maui followed by spread to the other islands in the archipelago. Evidence of significant genetic structure across islands indicates that contemporary dispersal is limited. Our findings parallel historical records of non-native poeciliid introductions and suggest that remediating invasion hotspots could reduce the risk of infection in native stream fishes, which illustrates how inferences on parasite co-introductions can improve conservation efforts by guiding responses to emerging infectious disease in species of concern.
