Many introduced species fail to interact strongly with the recipient biota, whereas others profoundly disrupt the ecosystems they invade through predation, competition, and other mechanisms. In the context of ecological impacts, research on biological invasions seldom considers phenotypic or microevolutionary changes that occur following introduction. Here, we show how plasticity in key life history traits ( colony size and longevity), together with omnivory, magnifies the predatory impacts of an invasive social wasp ( Vespula pensylvanica) on a largely endemic arthropod fauna in Hawaii. Using a combination of molecular, experimental, and behavioral approaches, we demonstrate (i) that yellowjackets consume an astonishing diversity of arthropod resources and depress prey populations in invaded Hawaiian ecosystems and (ii) that their impact as predators in this region increases when they shift from small annual colonies to large perennial colonies. Such trait plasticity may influence invasion success and the degree of disruption that invaded ecosystems experience. Moreover, post introduction phenotypic changes may help invaders to compensate for reductions in adaptive potential resulting from founder events and small population sizes. The dynamic nature of biological invasions necessitates a more quantitative understanding of how postintroduction changes in invader traits affect invasion processes.}, keywords = {Argentine ant, biological invasions, HAWAII, HYMENOPTERA, invasive species, Linepithema humile, overwintering, Pacific Insects, PREDATION, Vespidae, Vespula pensylvanica, Vespula vulgaris}, isbn = {0027-8424}, author = {Wilson, E.

Here, we use molecular genetic methods in an ecological context to demonstrate that endemic Hawaiian Hylaeus bees (Hymenoptera: Colletidae) selectively collect pollen from native plant species in Haleakala and Hawaii Volcanoes National Parks. We identified pollen DNA from the crops (internal storage organs) of 21 Hylaeus specimens stored in ethanol for up to 3~years. Genetic analyses reveal high fidelity in pollen foraging despite the availability of pollen from multiple plant species present at each study site. At high elevations in Haleakala, pollen was available from more than 12 species of flowering plants, but Hawaiian silversword (Argyroxiphium sandwicense subsp. macrocephalum) comprised 86\% of all pollen samples removed from bee crops. At lower elevations in both parks, we only detected pukiawe (Leptecophylla (Styphelia) tameiameiae) pollen in Hylaeus crops despite the presence of other plant species in flower during our study. Furthermore, 100\% of Hylaeus crops from which we successfully identified pollen contained native plant pollen. The molecular approaches developed in this study provide species-level information about floral visitation of Hawaiian Hylaeus that does not require specialized palynological expertise needed for high-throughput visual pollen identification. Building upon this approach, future studies can thus develop appropriate and customized criteria for assessing mixed pollen loads from a broader range of sources and from other global regions.}, keywords = {Colletidae, floral fidelity, foraging ecology, HAWAII, Hylaeus, HYMENOPTERA, MOLECULAR, native pollinators, Pacific Insects, pollination, silversword}, isbn = {1365-294X}, author = {Wilson, E.

We used the experimental control of ant numbers on two pairs of small (\<5\ ha) offshore islets dominated by either the big-headed ant, Pheidole megacephala or the tropical fire ant, Solenopsis geminata to investigate the influence of these species on seabird hatching success, fledging success and weight. Limited unpublished observations of both ant species attacking nesting seabirds exist, but the frequency of attacks or how they affect seabird growth and survival are unknown. Island-wide treatments with hydramethylnon resulted in the eradication of P. megacephala and the temporary reduction of S. geminata densities. No difference in hatching success, growth, or fledging success of Wedge-tailed Shearwaters (Puffinus pacificus), a common colonial nesting seabird in the Hawaiian Islands was observed on the pair of islets dominated by P. megacephala. On islets dominated by S. geminata, ant control resulted in a temporary increase in fledging success. Injury frequency increased dramatically on the untreated islet (8.3{\textendash}100\%) while remaining the same on the treated islet (27{\textendash}38\%). Severely injured chicks (i.e., chicks that lost \>20\% of tissue on their feet) weighed significantly less than uninjured chicks and did not fledge. It is unclear if the chicks were being preyed upon or stung in defense of nearby ant colonies. Radical changes in invasive ant populations have been noted, and booming ant populations could cause short-term, but widespread damage to seabird colonies.

We sequenced multiple DNA extractions from 20 individuals of four Hawaiian Hylaeus bee species known to be heteroplasmic. All species showed strong differences at polymorphic sites between abdominal and muscle tissue in most individuals, and only two individuals had no obvious segregation. Two specimens produced completely clean sequences from abdominal DNA. The fact that these differences are clearly visible by direct sequencing indicates that substantial intra-individual mtDNA diversity may be overlooked when DNA is taken from small tissue fragments. At the same time, differences in haplotype distribution among individuals may result in incorrect recognition of cryptic species. Because DNA barcoding studies typically use only a small fragment of an organism, they are particularly vulnerable to sequencing bias where heteroplasmy and haplotype segregation are present. It is important to anticipate this possibility prior to undertaking large-scale barcoding projects to reduce the likelihood of haplotype segregation confounding the results.}, keywords = {barcoding, Colletidae, HAWAII, Hylaeus, HYMENOPTERA, mtDNA, Pacific Insects}, isbn = {1755-0998}, author = {Magnacca, K.
