Duration of Protopolybia exigua exigua (de Saussure) nests and related aspects as influenced by phorid fly infestation (vespidae, polistinae, epiponini)

The main characteristics of 55 nests of Protopolybia exigua exigua were periodically evaluated in Ribeirão Preto, southeastern Brazil. Although the queens' life-span can eventually reach one year, nests barely thrive for six months because most of them are periodically invaded by the scavenger phorid fly, Megaselia aff. picta. Under heavy infestation the adult wasp population partially closes the nest entrance, migrates and constructs a new nest in the neighborhood. Afterwards the old-nest's entrance can be completely closed by the wasps which results in blocking the parasitoid flies inside. In the tropics, predation by ants is considered the main selective pressure which shaped most of the bionomic characteristics of Polistinae wasps. It is suggested that Megaselia can easily overcome the usual wasps defensive tactics just because they are so specialized against ants. Aerial raids, fast erratic-jerking movements, rapid and efficient oviposition behavior, etc. can eventually turn Megaselia into a very important enemy of some social wasps.

Well, what about intraspecific variation? Taxonomic and phylogenetic characters in the genus Synoeca de Saussure (Hymenoptera, Vespidae)

Cely and Sarmiento (2011) took issue with the cladistic analysis of relationships among species of the genus Synoeca by Andena et al. (2009a), and presented a reanalysis. They claimed that intraspecific variation in the genus is meaningful, and proper consideration yields a conclusion different from that of Andena et al. Both their critique and reanalysis are vitiated by numerous errors, as is shown in the present paper. © 2013 Magnolia Press.

Systematics and phylogeny of the Neotropical Pachymenes de Saussure and Santamenes Giordani Soika (Hymenoptera, Vespidae, Eumeninae)

The genera Pachymenes de Saussure and Santamenes Giordani Soika arerevised and the phylogenetic relationships among their species, based on external mor-phology and male genitalia, are presented. The cladistics analysis, using 22 terminalspecies (19 ingroup and 3 outgroup species) and 44 characters, produced a single clado-gram under implied weighting. Both genera were recovered as paraphyletic, althoughttwo major clades were formed and were well supported by the re-sampling analysis.We propose the synonymy of Pachymenes with Santamenes, and the description of twonew species: P. saussurei Grandinete n.sp. and P. riograndensis Grandinete n.sp..Newcombinations are: Pachymenes novarae (de Saussure) n.comb., P. olympicus (Zavattari)n.comb., P. peregrinus (Zavattari) n.comb. and P. santanna (de Saussure) revised combi-nation. We state the synonymy of P. obscurus orellanoides under P. obscurus consuetus,reviewing the status of the latter and raising P. consuetus to species level. Pachymenesorellanae vardyi is synonymized under P. orellanae; P. ghilianii olivaceus, P. ghilianiiavissimus and P. peruanus are proposed as synonyms of P. ghilianii; P. picturatusobscuratus is synonymized under P. laeviventris; P. picturatus nigromaculatus andP. picturatus var . intermedia are synonymized under P. picturatus and P. a t ra var . ornatis-sima get its lectotype designated and proposed as synonym of P. ater.

Review of Laws and Societies in the Canadian Prairie West, 1670-1940 Edited by Louis A. Knafla and Jonathan Swainger

For all intents and purposes, the settlement of the Canadian prairie was the founding of a new society using materials brought to the new land along with those close at hand. Of course, preexisting aboriginal society had to be supplanted in the course of this founding. In both the supplanting and the founding, the rule of law as we currently know it was a principal means and end of the settlement process.

Il concetto del "ma" e la musica di Tōru Takemitsu: traduzione di "The concept of 'ma' and the music of Takemitsu" di Jonathan L. Chenette

Lo scopo di questa tesi è di esplorare l'importanza del concetto giapponese del "ma" nella musica tradizionale, in particolare in quella del compositore Tōru Takemitsu, tramite la traduzione del saggio "The concept of 'ma' and the music of Tōru Takemitsu" (Jonathan L. Chenette, 1982) dall'inglese all'italiano. L'elaborato partirà da un'introduzione generale sul concetto del "ma" nella mentalità giapponese, per proseguire con la biografia di Tōru Takemitsu e una panoramica dei motivi che hanno portato a scegliere la traduzione del saggio di Chenette. Dopo la traduzione in sé e per sé e il commento della stessa, sarà anche fornito in appendice un glossario inglese-italiano della terminologia musicale utilizzata dall'autore all'interno del saggio.
