See detailNewt decline in Western Europe: highlights from relative distribution changes within guilds

The recent increase in the number of monitoring schemes has formed the basis for high quality distribution atlases. This provides the opportunity of estimating global and specific decline patterns across regional and national borders. In this framework, this study focused on four sympatric newt species—including the great crested newt (Triturus cristatus), an Annex 2 European Habitats Directive species, over six geographic areas (five countries) in Western Europe. A relative comparison of distribution maps across time is used here and is based on more than twelve thousands occupied grid cells. It benefits from the definition of a guild, as these species are simultaneously detectable in wetlands. T. cristatus and the alpine newt (Mesotriton alpestris) were the most and the least threatened newt species, respectively, whereas the palmate (Lissotriton helveticus) and smooth newt (Lissotriton vulgaris) had an intermediate decline level at both coarse and fine grain resolutions. However, regional variations across Europe and scale effects were also found. On one hand, these results show that T. cristatus is not only regionally threatened but suffers from a global decline in Western Europe. On another hand, the results indicate that patterns of decline are not uniform within Europe and that species often considered as common and not threatened are, in fact, declining more than others. Finally, the proposed methodology, i.e. using guilds to assess relative decline, would be useful as a complement to other standardized methods in correctly advising conservation managers and policy makers, particularly for species with more subtle declines.

Fish introduction is one of the main causes of amphibian decline worldwide. It affects particularly rare aquatic phenotypes such as paedomorphs, which retain gills during the adult stage. In this context, we determined whether small wetlands, such as pools surrounding fished and fishless lakes, could sustain paedomorphic and metamorphic newts. To this end, we surveyed lakes known historically to sustain Alpine newts (Ichthyosaura alpestris) as well as 35 nearby pools. On the basis of the published records, the only known population exhibiting paedomorphosis in the Swiss Alps was found to be extirpated by salmonid introductions. However, the metamorphs persisted in peripheral pools, paedomorphosis was discovered at a new locality, and overwintering larvae were still present in one of the lakes. These results show the importance of conserving varied aquatic habitats such as pools in mountainous environments where the main resources can become unsuitable for amphibians because of fish introductions. Pools may also function as reservoirs in maintaining newt populations until programs to remove fish from lakes can be carried out. It is not known if paedomorphs could reappear after fish removal. However, the combined resilience of amphibians after fish removal and the genetic basis for paedomorphosis highlighted in other taxa by previous studies suggest that there is the potential to maintain this intraspecific case of diversity even after its disappearance.

Rodentia are one of the most diverse orders among mammals, with more than 2,000 species currently described. Species assignation based on morphological data alone can present enormous challenges. In this study, we compared the applicability of 100 bp mini-barcodes from cytochrome b and cytochrome c oxidase 1 genes to enable rodent species identification. Based on GenBank sequence datasets of 115 rodent species, a 136 bp fragment of cytochrome b combined with universal rodent primers was selected as the most discriminatory mini-barcode. The efficacy of this new molecular tool was assessed on 946 samples including rodent tissues, feces, museum samples and feces/pellets from predators known to ingest rodents. Utilizing next generation sequencing technologies able to sequence multiple DNAs, 1,140 amplicons were tagged, multiplexed and sequenced together in one single 454 GS-FLX run. Our method was initially validated on a reference sample set including 265 clearly identified rodent tissues, corresponding to 103 different species. Following validation, 85.6% of 555 rodent samples from Europe, Asia and Africa whose species identity was unknown were able to be identified using the BLASTN program and GenBank reference sequences. In addition, our method proved effective even on degraded rodent DNA samples: 91.8% and 75.9% of samples from feces and museum specimens respectively were correctly identified. Finally, we succeeded in determining the diet of 66.7% of the investigated carnivores from their feces and 81.8% of owls from their pellets. Non-rodent species were also identified suggesting that our method is sensitive enough to investigate complete predator diets. This study demonstrates how this molecular identification method combined with high throughput sequencing can open new realms of possibilities in achieving fast, accurate and inexpensive species identification.

We update the study of the production of direct $J/\Psi$ in association with a $Z$ boson at the Next-to-Leading Order (NLO) in $\alpha_S$ by evaluating both the yield differential in $P_T$ and the $J/\Psi$ polarisation in the QCD-based Colour-Singlet Model (CSM). Contrary to an earlier claim, QCD corrections at small and mid $P_T$ are small if one assumes that the factorisation and the renormalisation scales are commensurate with the $Z$ boson mass. As it can be anticipated, the t-channel gluon-exchange (t−CGE) topologies start to be dominant only for $P_T > m_Z/2$. The polarisation pattern is not altered by the QCD corrections. This is thus far the first quarkonium-production process where this is observed in the CSM. Along the same lines, our predictions for direct $\Upsilon + Z$ are also given. [less ▲]

INTRODUCTION: Airway inflammation and remodelling in asthma occur in the large airways and also in the small airways. The small airways are those < 2 mm in diameter and are significant sites of chronic asthmatic inflammation. It is important, therefore, to target the small as well as the large airways in any strategy for effective treatment of this disease. AREAS COVERED: The present review deals with the recently developed fixed dose drug combination of beclometasone dipropionate/formoterol fumarate that emits extrafine particles when delivered from an innovative dry powder inhaler (DPI), NEXThaler(R). The aim is to present the technical and clinical aspects of aerosolized drug delivery to the lungs. EXPERT OPINION: The data show that the NEXThaler DPI is an efficient device for the management of persistent asthma. The evaluation of the inhalation profiles through the NEXThaler DPI demonstrates that device activation and consistent dose delivery occurs at patient achievable inhalation flow rates, and supports the broad utility of the NEXThaler DPI in patients with asthma. Overall, all the effectiveness, efficiency and satisfaction outcomes demonstrate the NEXThaler DPI is easy to use. [less ▲]

Au terme de cette convention FIRST, un savoir faire en matière de mesure d'odeur environnementale a été développé à sur le campus d'Arlon. Ce savoir faire étoffe ainsi l'acquis de l'équipe de recherche "Surveillance de l'Environnement". Un détecteur de nuisances olfactives a été développé en laboratoire. Ce système s'avère au moins aussi performant que les instruments proposés sur le marché. Dans notre cas, la technologie des nez artificiels a été adaptée au monitoring des odeurs dans l'environnement : notamment les influences des facteurs externes, comme la température et l'humidité ambiantes ont été étudiées. Les quelques odeurs environnementales (prélevées sur le terrain ou reconstituées artificiellement) testées sur le détecteur ont pu être identifiées par des techniques de reconnaissance de formes. Couplé à l'acquisiteur de données VIGIL de C2MS, un détecteur de terrain a été placé sur le terrain, aux alentours des bassins de décantation de la sucrerie "Tirlemont" de Genappe. Moyennant une calibration des algorithmes utilisés, il va donc servir à la surveillance continue des émissions olfactives sur le site considéré, notamment dans le but de mettre en évidence un indicateur d'alarme ou de délivrer un signal capable de contrôler un aérateur de bassin. A l'issue des 3 années de recherche, on peut donc considérer que l'instrument de laboratoire et le détecteur de terrain fonctionnent de manière satisfaisante et, en tout état de cause, suffisamment bien que pour être transposés à d'autres applications environnementales, au-delà de celle du monitoring des odeurs de sucrerie. Il est notamment projeté d'adapter une technique similaire à celle du détecteur de terrain au suivi des émissions olfactives aux alentours de décharges d'ordures, l'objectif étant le contrôle des dispositifs anti-odeurs. Chaque émission d'odeur est un cas spécifique : il sera donc difficilement envisageable, dans l'avenir, de commercialiser un appareil universel. Une perspective intéressante serait d'adapter le détecteur de terrain, au cas par cas, à d'autres suivis d'odeurs environnementales, en se servant des acquis de cette première expérience et de l'instrument de laboratoire comme banc d'essais préliminaires.

Major histocompatibility (MHC) class I gene expression is synergistically induced by the cytokines TNF-alpha and IFN-gamma. However, the mechanism that results in synergistic activation of these genes has remained unclear. We demonstrated here that TNF-alpha induced binding of NF kappa B p50 and p65 to the NF kappa B-like element of the MHC class I promoter termed region I and IFN-gamma induced binding of IRF-1 to the adjacent interferon consensus sequence (ICS). We further demonstrated that NF kappa B and IRF-1 physically interacted with each other and cooperatively induced MHC class I gene expression when cotransfected into CHP-126 neuroblastomas. These results provide a molecular mechanism by which TNF-alpha and IFN-gamma synergistically induce the expression of a variety of genes involved in immune responses, including MHC class I. [less ▲]
