First report of the exotic blue planarian, Caenoplana coerulea (Platyhelminthes, Geoplanidae), on Menorca (Balearic Islands, Spain)
-
In April 2009 two specimens of a terrestrial flatworm were collected from under a rock in an orchard at Ciutadella de Menorca on the easternmost Balearic island of Menorca (Spain). Their external morphology suggested that both specimens belonged to the invasive blue planarian Caenoplana coerulea, a species which is native to eastern Australia. Sequence data of a fragment of the mitochondrial cytochrome c oxidase subunit I (COI) and of the entire 18S ribosomal RNA confirm its identification. This is one of the first records of the species in Europe where it has only been found in one locality in the United Kingdom, France and NE Spain.

Fish remains from archaeological sites as indicators of former trade connections in the Eastern Mediterranean
-
The archaeozoological evidence that is available for the trade of fish in the Eastern Mediterranean area is summarized. This overview covers the Chalcolithic to the Crusader period and is based on data from 76 sites compiled from the literature and from as yet unpublished material under study by the authors. Remains of fish from the Nile, the Mediterranean and the Red Sea are regularly found in archaeological sites that are located outside the natural distribution of the fish species and thus indicate that they were transported as items of trade or exchange. Evidence for trade of Anatolian freshwater fish is also documented. The fish bone finds are discussed according to their provenance and the regions to which they were transported, and an attempt is made, on the basis of archaeological, artefactual and - if available - textual evidence, to understand the diachronic changes in the distribution within the broader economic and political contexts of the areas involved in the production and the consumption of fish.

Fishing at the Late Islamic settlement in Kharā’ib al-Dasht, Failaka Island, Kuwait
-
The Kharā’ib al-Dasht settlement, located on the north-eastern coast of the island of Failaka in Kuwait, has been excavated systematically since 2013 by the Kuwaiti-Polish Archaeological Mission. The investigated area yielded remains dated to the Late Islamic period, from the late seventeenth to the nineteenth century. In the northernmost part of the site, a fish processing area was uncovered, while the remains of residential structures (houses 1 and 2), as well as a mosque, were discovered in the eastern part of the site. Concentrations of fireplaces, hearths and ovens were discovered inside the houses and courtyards of what seems to be the centre of the settlement as well as from the periphery of the site. Fishing was evidenced not only by the presence of fish bones but also by recovered fishing technologies, including the remains of stone fish traps that were discovered in the coastal waters near to the site. The excavations yielded 12,182 bones of marine fishes. Twenty eight families are represented, including six families of cartilaginous fishes. Ariidae bones were most numerous followed by Haemulidae,Sciaenidae and Carcharhinidae. The analysis of the assemblage shows that fishing could have been of great importance to the inhabitants of the settlement. Moreover, we attest different patterns in the fish assemblages between the two different parts of the village. The fish processing area can be seen as a workplace, while the daily activity took place in the village. These differences can also be used to shed light on the fishing techniques these people used.

Fitness-heterozygosity associations differ between male and female winter moths Operophtera brumata L.
-
The association between heterozygosity and fitness is positive but weak on average and varies between studies. inbreeding has been invoked as the driving force between the positive heterozygosity-fitness associations, yet in spatio-temporally stable environments a negative correlation is expected. Furthermore, different patterns can arise because of the effects of natural selection on different loci and variation can be expected among groups of individuals that experience different levels of stress. In this paper we report on fitness-heterozygosity associations in the winter moth for six allozyme loci. The relationship is estimated for males and females separately, in four areas differing in their degree of fragmentation, and variation among loci is modelled. We introduce a linear mixed model framework to achieve this analysis. This approach differs from more traditional (multiple) regression analyses and allows testing specific interactions. We show that fitness, as estimated by body size, is negatively correlated with heterozygosity, but only so in females. This association does not vary significantly among loci and the four areas. We speculate that a trade-off between fitness-consequences of inbreeding and outbreeding at different stages of the winter moth life cycle could explain the observed patterns.
