The stomach contents of 40 great cormorants shot during "regulation" operations in the Pas-de-Calais have been analysed. Eight stomachs were empty and 426 fishes belonging to 15 species were recovered in the others. The dominant prey is the roach. Other regular prey are the common bream and the perch. Other fish (Salmonids, pike, pikeperch, ruffe, rudd, lamprey) appear in less than 5 stomachs. Most of the prey are small sized fish, less than 12 cm (total length). The biomass of 80% of the preys is less than 20g. However, the role of the greater fish in the diet must be emphasized: those weighing more than 200g (1% in numbers) reprensent 20% of the ingested biomass. [less ▲]

The Hoyoux hydrographic basin comprises two regions characterized by karstic phenomena and a rich hydrologic potential. On the one hand, the Condroz, where the Dinantian limestones are in synclinal position in the bottom of depressions, separated from one another by anticlinal crests which are occupied by the Upper Famennian sandstones. On the other hand, the narrow strip of Devonian limestones (of Givetian and Frasnian ages), positioned immediately at the NW of the previous region, separates the Condroz, which is constituted by an alternation of deposits of Famennian and Dinantian (sandstones and limestones) and, the Ardennes Condroz, which consists of lower devonian and eifelian deposits (conglomerates, quartzites, sandstones and schists). Since 2015, the Walloon Public Service's site "WalOnMap", using the ultra-precise digital terrain model "MNT 2013-2014 Hillshade" obtained after a LIDAR scan of the soil surface, offers a remarkable mapping tool essential to geological mapping, in general, and to the cartography and prospection of Karstic phenomena in particular.

Histiocytes belong to distinct groups of cells. Similarly, histiocytoses represent some pathologic expressions of the various histiocyte lineages recognized by their distinct phenotypes. The recognition of four major histiocytosis types relies on the distinction between monocytes-macrophages, dermal dendrocytes, Langerhans cells and the so-called indeterminate cells. Each of these groups exhibits a distinctive clinical and histological presentation. The risk of internal involvement, the prognosis and therapy are different as well. The diagnostic mainly relies on the clinico-pathologic assessment, and more particularly on the combination of histological, immunohistochemical and ultrastructural examinations. [less ▲]

The Belgium fauna includes 94 Elaterid species. Their intraspecific variations, phenology and distribution in Belgium were amalysed on the basis of samples collected during 150 years. UTM computed cartography allowed to describe the localization of every species and, in some cases, to point out some recent tendencies towards regression or expansion of geographic area. [less ▲]

We characterized the first POU-homeoprotein in a crustacean (designated APH-1 for Artemia POU-Homeoprotein, EMBL Y15070). The amino acid sequence of the APH-1 POU-domain is identical, except for two residues, to that of the two class III POU proteins Cf1-a (Drosophila) and POU-M1 (Bombyx mori). Southern blot analysis suggests that crustaceans have only one class III POU gene. RT-PCR and whole-mount in situ hybridization show that APH-1 mRNA is present in larvae specifically in the salt gland, an organ which is involved in osmoregulation, and disappears in the adult.

Aphids are well known for their role in virus transmission to host plant. In some cases, the virus is transmitted from plant to plant simply attached to the cuticule of the mouthparts or the forget. For other, circulative virus transmission based on virion internalization through the aphid gut followed by transfer to salivary glands and finally to next plant during aphid feeding is required. In both situations, presence of receptor components through the digestive tract of the aphids is needed for virus binding and further transmission to next plants even if not localized at the same place. In order to investigate the specific binding of virus on particular aphid receptors, two aphid-virus models were selected to be tested using several lectins showing differential sugar binding specificities. Virus transmission efficacy assays with Myzus persicae and potato virus but also Acyrthosiphon pisum and pea enation mosaic virus were performed using a range of lectins to assess the potential competition of lectins and virus. Some interesting lectins were found to reduce the virus transmission with a 2 fold factor showing potential use of lectin in virus spread control. The aphids were also investigated by a proteomic approach using a two Dimension-Differential in Gel Electrophoresis (2D-Dige) coupled with mass spectrometry to determine the aphid proteins involved in virus transmissions. Head or digestive tubes of aphids were collected and investigated for non persistant or persistant virus models respectively. Differential abilities of aphids to transmit the selected virus models are discussed in relation with lectin affinity specificity and investigated aphid proteins found to be involved in vector-virus interactions. The application of lectin as potential way to reduce virus transmission by aphids will also be developed. [less ▲]

« Omics » found recent developments due to significant improvement and availability of both separation and identification methods. For proteomics, functional information’s linked to the studied proteins was brought when compared to genomic approach. For these reasons, a panel of tools is available to determine the proteome patterns related to differential adaptation of insects to cope with plant defence mechanisms or to transmit virus. The adaptation and metabolic changes of aphids in relation to host plants focusing on the role of the bacterial endosymbionts was investigated. Use of artificial diet including diverse antibiotics but also the comparison of proteomes related to whole aphid and respective purified bacterial symbionts were studied to identify the respective origin and function of proteins constituting the studied proteomes. Diverse methods including 2D-DIGE, liquid chromatography coupled with mass spectrometry and data bank investigations were developed. From the proteome investigation, characterisation of good and bad virus vectors was also performed in different aphid - plant - virus models. Particular proteins of interest were selected. This broad proteomic approach will be discussed as an interesting and reliable tool to study the biologically involved proteins from aphids in response to several environmental changes [less ▲]
