Role of social wasps in Saccharomyces cerevisiae ecology and evolution
It is demonstrated that queens of social wasps overwintering as adults (Vespa crabro and Polistes spp.) can harbor yeast cells from autumn to spring and transmit them to their progeny and indicate that wasps are a key environmental niche for the evolution of natural S. cerevisiae populations, the dispersion of yeast cells in the environment, and the maintenance of their diversity.

The taxonomic level order as a possible tool for rapid assessment of Arthropod diversity in agricultural landscapes
This paper proposes the methodology as a possible useful short-cut to assess biodiversity in agricultural landscapes at a local scale and tests the reliability of two higher taxa as surrogates for Arthropod diversity: order for all the specimens and family for Coleoptera and shortening the sampling period.

On status badges and quality signals in the paper wasp Polistes dominulus: body size, facial colour patterns and hierarchical rank
It is suggested that body size is a reliable quality indicator on which wasps build their social networks, and that clypeus patterning is not involved. Expand
Rank and epicuticular hydrocarbons in different populations of the paper wasp Polistes dominulus (Christ) (Hymenoptera, Vespidae)
The aim was to identify specific compounds or sets of compounds which could be general indexes of foundress rank position in an associative foundation and found quantitative and qualitative differences in the epicuticular profile among the three populations. Expand
The generalism-specialism debate: the role of generalists in the life and death of species
It is argued that generalism in resource use, biotope occupancy, and niche breadth not only exists, but also forms a crucial part in the evolution of specialists, representing a vital force in speciation and a more effective insurance against extinction. Expand
Social dominance molds cuticular and egg chemical blends in a paper wasp
It is demonstrated that, contrary to the widely accepted view, dominance, rather than fertility, determines chemical signatures in Polistes wasps, which explains why queens can recognize their own eggs and police reproduction by subordinates if they become fertile and lay eggs. Expand
Beyond odor discrimination: demonstrating individual recognition by scent in Lemur catta.
It is demonstrated that recognition of conspecific odors goes beyond the perception of cues other than individuality and that the receiver actually forms a mental representation of a specific individual by its scent. Expand
recluster: an unbiased clustering procedure for beta‐diversity turnover
When dissimilarity matrices of faunistic and phylogenetic beta-diversity turnover indices are projected in dendrograms, a high frequency of ties and zero values produces trees whose topology andExpand
Reproductive isolation and patterns of genetic differentiation in a cryptic butterfly species complex
Comparisons of genetic divergence across western Eurasia in an extensive data set of mitochondrial and nuclear DNA sequences with behavioural data on inter‐ and intraspecific reproductive isolation in courtship experiments suggest that additional hidden diversity is unlikely to occur in Europe.

Cuticular Hydrocarbons of Polistes dominulus as a Biogeographic Tool: A Study of Populations from the Tuscan Archipelago and Surrounding Areas
It is shown that cuticular hydrocarbon patterns of Polistes dominulus are consistent with similarities among northern Tyrrhenian islands, as reported in previous biogeographic studies. Expand
