Data from: Partitioning resources through the seasons: abundance and phenology of carrion beetles (Silphidae) in southeastern Ontario
<p>The coexistence of ecologically similar species is thought to require resource partitioning to minimize competition. Phenological, seasonal differences in activity may provide an important axis for resource partitioning. Here, we test for evidence of seasonal differences in activity within a diverse guild of carrion beetles (Silphidae) in a habitat preserve on the Frontenac Arch, southeastern Ontario, Canada using a large-scale survey during their active seasons (April to October). We then used generalized additive models to test for differences in seasonal abundance among eight co-occurring carrion beetle species, including five species of burying beetles (Nicrophorinae: <i>Nicrophorus </i>Fabricius, 1775) and three species from the Silphinae subfamily. Consistent with previous work, all species showed seasonal variation in abundance, with peak abundance of most species occurring between June and August. All but one species (<i>Nicrophorus sayi </i>Laporte, 1840) showed positive relationships between abundance and temperature. We find evidence consistent with seasonal partitioning of resources among <i>Nicrophorus </i>habitat generalists that could potentially reduce competition for limited carrion resources. In contrast, we find little evidence for seasonal differences in abundance among <i>Nicrophorus </i>habitat specialists, which instead may partition resources spatially. Overall, our results provide evidence consistent with an important role for seasonal resource partitioning among carrion beetle species that show higher levels of spatial (habitat) overlap within a temperate beetle guild.</p>
Data from: Unearthing carrion beetles' microbiome: characterization of bacterial and fungal hindgut communities across the Silphidae
Carrion beetles (Coleoptera, Silphidae) are well known for their behaviour of exploiting vertebrate carcasses for nutrition. While species in the subfamily Silphinae feed on large carcasses and on larvae of competing scavengers, the Nicrophorinae are unique in monopolizing, burying and defending small carrion, and providing extensive biparental care. As a first step towards investigating whether microbial symbionts may aid in carcass utilization or defence, we characterized the microbial hindgut communities of six Nicrophorinae (Nicrophorus spp.) and two Silphinae species (Oiceoptoma noveboracense and Necrophila americana) by deep ribosomal RNA amplicon sequencing. Across all species, bacteria in the family Xanthomonadaceae, related to Ignatzschineriao larvae, were consistently common, and several other taxa were present in lower abundance (Enterobacteriales, Burkholderiales, Bacilli, Clostridiales and Bacteroidales). Additionally, the Nicrophorinae showed high numbers of unusual Clostridiales, while the Silphinae were characterized by Flavobacteriales and Rhizobiales (Bartonella sp.). In addition to the complex community of bacterial symbionts, each species of carrion beetle harboured a diversity of ascomycetous yeasts closely related to Yarrowia lipolytica. Despite the high degree of consistency in microbial communities across the Silphidae—specifically within the Nicrophorinae—both the fungal symbiont phylogeny and distance-based bacterial community clustering showed higher congruence with sampling locality than host phylogeny. Thus, despite the possibility for vertical transmission via anal secretions, the distinct hindgut microbiota of the Silphidae appears to be shaped by frequent horizontal exchange or environmental uptake of symbionts. The microbial community profiles, together with information on host ecology and the metabolic potential of related microorganisms, allow us to propose hypotheses on putative roles of the symbionts in carcass degradation, detoxification and defence.
Data from: Taxonomic revision of genus Ablattaria Reitter (Coleoptera, Silphidae) employing geometric morphometrics
The genus Ablattaria Reitter, 1884 (Coleoptera: Silphidae: Silphinae) is revised. Four taxa are recognized as valid species: Ablattaria arenaria (Kraatz, 1876), A. cribrata (Ménétries, 1832), A. laevigata (Fabricius, 1775) and A. subtriangula Reitter, 1905. Ablattaria laevigata var. meridionalis Ganglbauer, 1899 is newly treated as a junior subjective synonym of A. laevigata. Lectotypes are designated for Phosphuga arenaria Kraatz, 1876, Ablattaria arenaria var. punctigera Reitter, 1884, Ablattaria arenaria var. alleoni Portevin, 1926, Silpha cribrata Ménétries, 1832, Silpha laevigata Fabricius, 1775, Silpha gibba Brullé, 1832, Ablattaria gibba var. costulata Portevin, 1926, Ablattaria gibba var. distinguenda Portevin, 1926, Ablattaria gibba var. punctata Portevin, 1926 and Ablattaria subtriangula Reitter, 1905. The distribution of all taxa is mapped, based on material examined. Geometric morphometric methods were used to evaluate shape variability in Ablattaria. Results indicated sexual dimorphism in all species. Shape inconsistency was found between the sexes of all taxa when tested independently. The first two relative warp axes indicated 65.17% shape variation in males and 65.72% in females. Canonical variate analysis separated the taxa studied. There was minimal overlap between some groups in both sexes. Differences in body shape between populations of A. laevigata from Central Europe, Italy and Greece + Turkey were also examined. Relative warps implied 58.01% shape variability on both axes in males and 64.78% in females. CVA revealed noticeable overlaps between the groups, although the Italian population demonstrated a higher separation in both sexes.
