Abstract

Dung removal by macrofauna such as dung beetles is an important process for nutrient cycling in pasturelands. Intensification of farming practices generally reduces species and functional diversity of terrestrial invertebrates, which may negatively affect ecosystem services. Here, we investigate the effects of cattle-grazing intensification on dung removal by dung beetles in field experiments replicated in 38 pastures around the world. Within each study site, we measured dung removal in pastures managed with low- and high-intensity regimes to assess between-regime differences in dung beetle diversity and dung removal, whilst also considering climate and regional variations. The impacts of intensification were heterogeneous, either diminishing or increasing dung beetle species richness, functional diversity, and dung removal rates. The effects of beetle diversity on dung removal were more variable across sites than within sites. Dung removal increased with species richness across sites, while functional diversity consistently enhanced dung removal within sites, independently of cattle grazing intensity or climate. Our findings indicate that, despite intensified cattle stocking rates, ecosystem services related to decomposition and nutrient cycling can be maintained when a functionally diverse dung beetle community inhabits the human-modified landscape.

Abstract

A phylogenetic analysis of Drepanocerina based on 81 morphological characters was conducted using various analytical approaches (Maximum Parsimony, New Technology Search, Bayesian Inference, and Phylogenetic Networks Analysis). Twelve lineages ranked at the generic level were resolved, with full congruency among the four analytical methods. Results allowed to propose two new genera, which are herein described as Paraixodina gen. nov. and Epidrepanus gen. nov. In addition, the previously unknown Eodrepanus integriceps and Sinodrepanus similis females were identified and described. A biogeographic analysis was performed based on 14 geographic macro-areas, partitioning the subtribe and outgroup distributional ranges. Based on the inferred phylogeny and biogeography, an ancestral distribution and radiation scenario from the Central East Africa macroarea (Afrotropical Region) was proposed. The biogeographic implications of past and present-day relationships within Drepanocerina was discussed.

29. Geotrupes rossii Jekel, 1866 (currently Ceratophyus rossii), nomen protectum. (Coleoptera, Scarabaeoidea, Geotrupidae)

Abstract

The authors present evidence that, in accordance with Article 23.9 of the Code, Geotrupes rossii Jekel, 1866, despite a junior primary homonym of Geotrupes rossii Rosenhauer, 1856, warrants the status of valid name for the species currently known as Ceratophyus rossii (Jekel, 1866).

38. A new cryptic ground beetle species from the Alps characterised via geometric morphometrics

Author

Abstract

The European Alps support several ground beetle Nebria (Nebriola) species, which are morphologically similar. A study conducted on a Nebriola population located between the Eastern Pennine and Western Lepontine Italian Alps revealed the presence of two species, Nebria (Nebriola) cordicollis and N. (Nebriola) gosteliae, and some individuals that possibly represented an unknown taxonomic unit (UTU). Therefore, to further elucidate and characterise the morphological units at the site, we completed a comparative analysis using geometric morphometrics applying the semilandmarks approach. We examined the pronotum, the right elytron, and the median lobe of aedeagus. The quantitative analysis evaluated the overall variation in shape and size of the three structures. Results supported the hypothesised presence of three distinct groups of individuals, with different morphologies for the anatomical traits examined. The pronotum and median lobe of aedeagus exhibited more marked differences among the groups, while the right elytron showed reduced differentiation. These results confirmed that the three groups were separate taxa, and were therefore correctly classified. Based on our findings, we considered the UTU a new species, which is here described as Nebria (Nebriola) casalei sp. nov.
