La pratique de l’entomologie du terrain au conservatoire ou l’essentiel est de bien transmettre
-
The principles and conventions concerning research, killing, treatment, preparation and classification of insects in collections are discussed in this note. A special attention to the labeling and related items are recalled with the aim of harmonizing practices and correcting drifts observed over the time.

La pratique de l’inhumation dans des contenants périssables dans la Syrie antique entre le Ier et le VIIe siècle après J.-C.
-
Cette étude vise à identifier les contenants périssables utilisés pour l’inhumation des morts dans la région de la Syrie antique pendant la période romaine. Le travail inclut l’étude d’environ cent tombes dans neuf espaces funéraires. L’analyse des sépultures a été réalisée soit sur le terrain, à Palmyre et Es-Samra, soit à partir des documentations graphiques et écrites dans les autres sites. Cette analyse est fondée d’une part sur les vestiges disponibles et d’autre part sur l’analyse taphonomique des squelettes. Les données recueillies ont permis de démontrer l’existence de plusieurs types de contenants utilisés pour des sujets immatures et adultes. Elles ont permis aussi d’évoquer le statut social des individus concernés par ces pratiques funéraires.

Lanice conchilega structures carbon flows in soft-bottom intertidal areas
-
Biogenic reefs constructed by the tube-building ecosystem engineer Lanice conchilega (Terrebilidae, Polychaeta) have profound structuring impacts on the benthic environment in that they alter the biogeochemical and physical properties of the sediment. This study provides new insights into the functioning and effects on food webs of L. conchilega reefs in intertidal sediments using linear inverse models to quantify the carbon flows in the food webs in the presence and absence of the tubeworm. The inverse food web models were based on an empirical dataset from 2 study sites, which provided biomass and stable isotope data, and information on general physiological constraints from the literature. Results of the model showed that the carbon input into reef food webs (mean ± SE; 191 ± 50 mmol C m−2 d−1) is ca. 40 times higher compared to bare sand areas (5 ± 2 mmol C m−2 d−1) and is mainly derived from organic matter (OM) in the water column. Most of the OM input towards these reefs is consumed by suspension-feeding macrofauna, particularly L. conchilega; however, the worm is not an important source of carbon for other macrofaunal organisms. The ratio of OM input to primary production indicates that the OM needs to be produced in an area at least 15 times larger than the reef area, demonstrating significant OM ‘focussing’ within the reef food web. The reef structures created by L. conchilega act as a trap for OM, resulting in an overall higher macrofaunal biomass and much more diverse food webs than in the absence of the tubeworm.

Lasioglossum dorchini (Hymenoptera: Apoidea: Halictidae) a new species of bee from Israel
-
This paper describes a new species, Lasioglossum dorchini, occuring in sand dunes in Israel. It is close to Lasioglossum leptocephalum. Its phylogenetic relationships with the other species of the virens/littorale group are analyzed

Late burial to early tectonic quartz veins in the periphery of the High-Ardenne slate belt (Rursee, north Eifel, Germany)
-
A detailed structural mapping and geometrical analysis of distinct bedding-(sub)perpendicular and bedding-parallel quartz veins has been performed in the northeastern part of the High-Ardenne slate belt (Rursee, North Eifel, Germany), with the aim to reconstruct the local fracturing/veining history. The structural relationship of these two types of veins as well as their relationship with cleavage, folds and faults allows attributing a pre- to early-Variscan age to these veins. The first type of veins is oriented (sub)perpendicular to bedding and consists of several, mutual cross-cutting generations, which clearly predate Variscan deformation. The second type of veins, bedding-parallel veins, post-dates the bedding-(sub)perpendicular veins and reflects bedding-parallel thrusting at the onset of Variscan deformation, predating folding. Subsequently, during progressive Variscan compression both types of veins were passively folded within characteristic, NW-vergent, overturned folds. Locally, due to flexural slip folding, reactivation along the bedding-parallel veins may have taken place.
