Abstract Many social species show variation in their social structure in response to different environmental conditions. For example, colonies of the yellowjacket waspVespula squamosaare typically headed by a single reproductive queen and survive for only a single season. However, in warmer climates,V. squamosacolonies sometimes persist for multiple years and can grow to extremely large size. We used genetic markers to understand patterns of reproduction and recruitment within these perennial colonies. We genotypedV. squamosaworkers, pre‐reproductive queens, and males from perennial colonies in the southeastern United States at 10 polymorphic microsatellite loci and one mitochondrial DNA locus. We found thatV. squamosafrom perennial nests were produced by multiple reproductives, in contrast to typical annual colonies. Relatedness of nestmates from perennial colonies was significantly lower than relatedness of nestmates from annual colonies. Our analyses of mitochondrial DNA indicated that mostV. squamosaperennial colonies represented semiclosed systems whereby all individuals belonged to a single matriline despite the presence of multiple reproductive females. However, new queens recruited into perennial colonies apparently mated with non‐nestmate males. Notably, perennial and annual colonies did not show significant genetic differences, supporting the hypothesis that perennial colony formation represents an instance of social plasticity. Overall, our results indicate that perennialV. squamosacolonies show substantial changes to their social biology compared to typical annual colonies and demonstrate variation in social behaviors in highly social species.

A New Species of Viscachataenia (Cestoda: Anoplocephalidae) from the Southern Mountain Viscacha, Lagidium viscacia (Hystricomorpha: Chinchillidae), in Boliva
Anoplocephalid cestodes collected from the southern mountain viscacha, Lagidium viscacia, in Boliva in 1986 are here examined, and a new species of Viscachataenia is described. The new species has numerous body measurements that are larger than the existing species, V. quadrata, but the eggs and corresponding structures of the new species are all smaller than those of V. quadrata

Stabb, Eric V. (Ed.)ABSTRACT Dimethylsulfoniopropionate (DMSP), a key component of the global geochemical sulfur cycle, is a secondary metabolite produced in large quantities by marine phytoplankton and utilized as an osmoprotectant, thermoprotectant, and antioxidant. Marine bacteria can use two pathways to degrade and catabolize DMSP, a demethylation pathway and a cleavage pathway that produces the climate-active gas dimethylsulfide (DMS). Whether marine bacteria can also accumulate DMSP as an osmoprotectant to maintain the turgor pressure of the cell in response to changes in external osmolarity has received little attention. The marine halophile Vibrio parahaemolyticus contains at least six osmolyte transporters, namely four betaine carnitine choline transport (BCCT) carriers (BccT1 to BccT4) and two ATP-binding cassette (ABC) family ProU transporters. In this study, we showed that DMSP is used as an osmoprotectant by V. parahaemolyticus and by several other Vibrio species, including Vibrio cholerae and Vibrio vulnificus . Using a V. parahaemolyticus proU double mutant, we demonstrated that these ABC transporters are not required for DMSP uptake. However, a bccT null mutant lacking all four BCCTs had a growth defect compared to the wild type (WT) in high-salinity medium supplemented with DMSP. Using mutants possessing only one functional BCCT in growth pattern assays, we identified two BCCT family transporters, BccT1 and BccT2, that are carriers of DMSP. The only V. parahaemolyticus BccT homolog that V. cholerae and V. vulnificus possess is BccT3, and functional complementation in Escherichia coli MKH13 showed that V. cholerae VcBccT3 could transport DMSP. In V. vulnificus strains, we identified and characterized an additional BCCT family transporter, which we named BccT5, that was also a carrier for DMSP. IMPORTANCE DMSP is present in the marine environment, produced in large quantities by marine phytoplankton as an osmoprotectant, and is an important component of the global geochemical sulfur cycle. This algal osmolyte has not been previously investigated for its role in marine heterotrophic bacterial osmotic stress response. Vibrionaceae species are marine species, many of which are halophiles exemplified by V. parahaemolyticus , a species that possesses at least six transporters for the uptake of osmolytes. Here, we demonstrated that V. parahaemolyticus and other Vibrio species can accumulate DMSP as an osmoprotectant and show that several BCCT family transporters uptake DMSP. These studies suggest that DMSP is a significant bacterial osmoprotectant that may be important for understanding the fate of DMSP in the environment. DMSP is produced and present in coral mucus, and Vibrio species form part of the microbial communities associated with corals. The function of DMSP in these interactions is unclear, but it could be an important driver for these associations, allowing Vibrio proliferation. This work suggests that DMSP likely has a more important role in heterotrophic bacteria ecology than previously appreciated.more » « less

Abstract Ranges of tardigrade intraspecific and interspecific variability are not precisely defined, both in terms of morphology and genetics, rendering descriptions of new taxa a cumbersome task. This contribution enhances the morphological and molecular dataset available for the heterotardigrade genusViridiscusby supplying new information on Southern Nearctic populations ofV.perviridis,V.viridianus, and a new species from Tennessee. We demonstrate that, putting aside already well-documented cases of significant variability in chaetotaxy, the dorsal plate sculpturing and other useful diagnostic characters, such as morphology of clavae and pedal platelets, may also be more phenotypically plastic characters at the species level than previously assumed. As a result of our integrative analyses,V.viridianusis redescribed,V.celatussp. nov. described, andV.clavispinosusdesignated asnomeninquirendum, and its junior synonymy with regard toV.viridianussuggested. Morphs of threeViridiscusspecies (V.perviridis,V.viridianus, andV.viridissimus) are depicted, and the implications for general echiniscid taxonomy are drawn. We emphasise that taxonomic conclusions reached solely through morphological or molecular analyses lead to a distorted view on tardigrade α-diversity.more » « less

Context.Accurate42Ti(p,γ)43V reaction rates are crucial for understanding the nucleosynthesis path of the rapid capture process (rpprocess) that occurs in X-ray bursts. Aims.We aim to improve the thermonuclear rates of42Ti(p,γ)43V based on more complete resonance information and a more accurate direct component, together with the recently released nuclear masses data. We also explore the impact of the newly obtained rates on therpprocess. Methods.We reevaluated the reaction rate of42Ti(p,γ)43V by the sum of the isolated resonance contribution instead of the Hauser-Feshbach statistical model. We used a Monte Carlo method to derive the associated uncertainties of new rates. The nucleosynthesis simulations were performed via the NuGrid post-processing code ppn. Results.The new rates differ from previous estimations due to the use of a series of updated resonance parameters and a direct S factor. Compared with the previous results from the Hauser-Feshbach statistical model, which assumes compound nucleus43V with a sufficiently high-level density in the energy region of astrophysical interest, large differences exist over the entire temperature region ofrp-process interest, up to two orders of magnitude. We consistently calculated the photodisintegration rate using our new nuclear masses via the detailed balance principle, and found the discrepancies among the different reverse rates are much larger than those for the forward rate, up to ten orders of magnitude at the temperature of 108K. Using a trajectory with a peak temperature of 1.95×109K, we performed therp-process nucleosynthesis simulations to investigate the impact of the new rates. Our calculations show that the adoption of the new forward and reverse rates result in abundance variations for Sc and Ca of 128% and 49%, respectively, compared to the variations for the statistical model rates. On the other hand, the overall abundance pattern is not significantly affected. The results of using new rates also confirm that therp-process path does not bypass the isotope43V. Conclusions.Our study found that the Hauser-Feshbach statistical model is inappropriate to the reaction rate evaluation for42Ti(p,γ)43V. The adoption of the new rates confirms that the reaction path of42Ti(p,γ)43V(p,γ)44Cr(β+)44V is a key branch of therpprocess in X-ray bursts.more » « less

Abstract Vairimorpha (=Nosema) ceranaeis a widespread pollinator parasite that commonly infects honeybees and wild pollinators, including bumblebees. Honeybees are highly competentV. ceranaehosts and previous work in experimental flight cages suggestsV. ceranaecan be transmitted during visitation to shared flowers. However, the relationship between floral visitation in the natural environment and the prevalence ofV. ceranaeamong multiple bee species has not been explored. Here, we analyzed the number and duration of pollinator visits to particular components of squash flowers—including the petals, stamen, and nectary—at six farms in southeastern Michigan, USA. We also determined the prevalence ofV. ceranaein honeybees and bumblebees at each site. Our results showed that more honeybee flower contacts and longer duration of contacts with pollen and nectar were linked with greaterV. ceranaeprevalence in bumblebees. Honeybee visitation patterns appear to have a disproportionately large impact onV. ceranaeprevalence in bumblebees even though honeybees are not the most frequent flower visitors. Floral visitation by squash bees or other pollinators was not linked withV. ceranaeprevalence in bumblebees. Further,V. ceranaeprevalence in honeybees was unaffected by floral visitation behaviors by any pollinator species. These results suggest that honeybee visitation behaviors on shared floral resources may be an important contributor to increasedV. ceranaespillover to bumblebees in the field. Understanding howV. ceranaeprevalence is influenced by pollinator behavior in the shared floral landscape is critical for reducing parasite spillover into declining wild bee populations.more » « less
