In 2016, archaeological excavations undertaken by the Ephorate of Antiquities of West Attica, Piraeus and Islands 3.8 km south-west of Athens, Greece, revealed mass burials of 79 skeletons in three rows. The burials are dated to the 7th century BC. The anthropological field documentation was undertaken by The Swedish Institute of Athens, and followed established bioarchaeological protocols regardi

Results suggest that a single female is equally good at producing a 2nd brood as a pair, and that female density during the 1st oviposition period does not influence the size of the 2nd brood. Female residence time with the 1st brood, body size, weight and lipid content explained little of the large variation in 2nd brood size. -from Authors

The external differences between the well‐documented S. scolytus and the little studied S. laevis are clarified with the help of SEM micrographs of the frons and abdomen of both sexes of the two species. The convex frons of both male and female S. scolytus is densely covered with short hairs. S. laevis males have a flat frons with long hairs in a pair of bundles, whereas the females have a convex

Two rings of pheromone-baited sticky traps surrounded the elm wood at 20-300m and 1-2km outside the forest edge. Most Scolytus were caught at sites in the inner ring near the forest;

A model is presented that describes the reemergence of parent spruce bark beetles, Ips typographus, based on breeding density and temperature conditions. Laboratory data obtained at one constant temperature provide the distribution of reemergence time and different combinations of threshold temperatures and degreedays (°D) at mean reemergence. Of these combinations, 167.71 °D above 7.5 °C gave the

Parents re-emerged sooner at higher densities but the total proportion that re-emerged was independent of density. Over 20 offspring per female were produced at the lowest density (0.5/100 cm2) but only 0.6 per female at the highest density (31/100 cm2). Offspring from the lowest density were about 50% heavier than those from the highest density and also the fat content increased with decreasing d

An experiment to investigate the dispersal and supposed reattack by parent spruce bark beetles, Ips typographus (L.), was performed. More than 20,000 parent beetles were marked with fluorescent powder and immediately released from platforms when they reemerged from trees attacked during the spring swarming. Thirty‐eight marked and over 8000 unmarked beetles were trapped on sticky traps covering 21

Summary Objective There is limited knowledge on sick leave associated with arthroscopic partial meniscectomy (APM) due to traumatic meniscal tear and its potential gender differences. Thus, our aim was to determine gender-specific sick leave before and after APM. Method In Skåne region, Sweden, we identified patients, aged 18–59 years diagnosed with traumatic meniscal tear without ligament injury,

Lidar is a powerful technique normally associated with atmospheric monitoring. However, lidar techniques, also of the laser-induced fluorescence and laser-induced breakdown spectroscopy varieties, provide many new possibilities in unconventional fields including cultural heritage and ecological applications.

Purpose: Self-harm is common among adolescents, and is even more frequent among psychiatric populations. The aim of this study was to increase knowledge and understanding of different aspects of life for adults who, when adolescents, had engaged in severe self-harm during inpatient stays.Material and methods: Individual semi-structured interviews were held with seven former inpatients with a histo

In this article we present data from two experiments on the association between individual asymmetry and fitness in the winter moth. We performed a mate selection experiment and compared asymmetry and body size of mated and unmated males collected in the field. Individual asymmetry was not associated with copulation probability, adult life span, or body size, even though body size is a reliable in

Inter- and intraspecific amino acid variability in the pheromone binding proteins (PBPs) of the Lepidoptera is believed to contribute to a molecular mechanism of pheromone blend discrimination. Messenger RNA coding for PBP sequence in Agrotis segetum (Noctuidae) was cloned, and nucleotide and inferred amino acid variation across a 769-bp region of a PBP locus was studied in two populations. A sing

Broad-sense heritability of fluctuating asymmetry and developmental instability in the winter moth were analysed in a full-sib breeding experiment. Effects of both genetic background and common environment on both tibia FA (measured for the three pairs of legs) and body size were studied. As body size has previously been shown to be a reliable indicator of larval feeding success and expected fitne

Analysis of female sex pheromone gland extracts of the turnip moth (or common cutworm), Agrotis segetum, from Zimbabwe revealed three compounds previously identified as sex pheromone components in the Swedish population, namely (Z)-5-decenyl acetate (Z5-10:OAc), (Z)-7-dodecenyl acetate (Z7- 12:OAc), and (Z)-9-tetradecenyl acetate (Z9-14:OAc). However, the proportions from the Zimbabwean population

Measurements of single neurone activity in the peripheral pheromone receptors of male Agrotis segetum (Denis and Schiffermuller) (Lepidoptera: Noctuidae) were performed in a wind tunnel using a portable electrophysiological recording unit. Filter paper and rubber septa loaded with synthetic sex pheromone, as well as individual conspecific female glands, were used as pheromone sources. Recordings,

Pheromone gland extracts from calling female Plodia interpunctella contained at least seven compounds that consistently elicited electroantennographic responses from male antennae upon gas chromatographic analysis. Three of these compounds were found to be the previously identified gland constituents, i.e., (Z,E)-9,12-tetradecadienyl acetate (Z9,E12-14:OAc), (Z,E)-9,12-tetradecadienal (Z9,E12-14:A

Understanding the mechanisms that determine the development of a bilaterally symmetrical trait is crucial to the interpretation of patterns of fluctuating asymmetry (FA). Experimental and theoretical studies have indicated that feedback mechanisms both within and between developing traits, may participate in the developmental control of asymmetry. This study provides evidence that naturally occurr

The leaf volatiles emitted from four nonhost tree species of lps typographus, i.e. Betula pendula, B. pubescens, Populus tremula, and Sambucus nigra, were collected outdoors by headspace sampling in situ and analyzed by GC-MS. Three major classes of compounds, aliphatics [mainly green-leaf volatiles (GLVs)], monoterpenes, and sesquiterpenes, existed in all the deciduous tree species investigated.
