The erosion of biodiversity is caused by many factors. Large ungulates, which occupy a large part of the Walloon forests, can also influence the distribution and dynamics of plant species. Therefore, they impact the biodiversity of our temperate forests. The aim of the present study is to identify changes in forest understory vegetation due to the pressure exerted by wild ungulates thanks to an exclosure-enclosure experiment. This study was conducted on a high plateau of the Ardenne, in the forest of St Michel Freyr (South Belgium). The forested area is dominated by beech and spruce where red deer, wild boar and roe deer are living in sympatry. 150 sampling plots were established in 2000. Each plot consisted of two closed enclosures of 4 m² each and one exclosure of 4 m² as control under pressure of ungulates. Sampling was carried out systematically by a 500m-square mesh. The cover rate and height of some easily identifiable species were measured regularly since 2000 (2001, 2002, 2003, 2004, 2007, 2011-2012). In addition, we identified each herbaceous species in 2011-2012 to analyze the species richness after more than 10 years exclosure. Ligneous species showed an increase of developpement in the fenced area. These species are more impacted when they are not much represented in the study site.Species richness and diversity are higher in areas impacted by herbivory. Monocotyledons are mainly favorised while tree seedlings are unfavorised. Browsing on the trees keeps the area free from high vegetation and allows light to reach the ground. In the same time, herbaceous species have a lower cover rate in the enclosure because of the competitive exclusion induced by shrub and tree seedlings layer. If the apparition of most species is favorised by ungulates, they induce a lag of gowth on dicotyledons which have a higher palatability than monocotyledons. Ungulates have the ability to impact the distribution of vegetal species by the modification of the competitive interaction. By their pressure on tree and shrub species, they induce a higher diversity of the ground flora. However, this change in vegetation composition is slow and requires a long-term studie, specially in areas of low biomass productivity like the St-Hubert forest. [less ▲]

During the past decades, Belgian and European agriculture encountered several crises and as a result, food safety and quality have become governmental issues. This has led to vertical coordination and the appearance of quality conventions between links in the food supply chain. In practice, the quality conventions initiated by changed institutional settings turned out to be compulsory. This research aims to assess the exclusion-effect of this process and this is undertaken through data-analysis concerning farmers' participation in certification initiatives and homogeneity analysis. The results of a survey concerning 319 Belgian farmers show that 25% of the farmers are not involved in any initiative of quality improvement. They are significantly older and less educated, but have also very little access to farmers' organisations and extension. Their gross margin is lower in comparison with participants; they are more oriented to one specialisation and are less labour intensive. The combination of these elements can be seen as a constraint to enter initiatives and as a probable danger to exclude the concerned farmers from the market. This paper further elaborates upon these results, but also studies farmers' opinion regarding laws, contracts and labels. Finally, some recommendations towards public policies are made. [less ▲]

The implementation of exclusive diffractive production of Higgs boson and dijets in the FPMC (Forward Physics Monte Carlo) framework is presented following the models by Khoze, Martin, Ryskin and Cudell, Dechambre, Hernandez and Ivanov. The predictions of the models are compared to the CDF measurement of exclusive jets and the uncertainties on the Higgs boson and jet production cross sections at the LHC are discussed. [less ▲]

We study pp and pp collisions which lead to the exclusive production of J/psi or Upsilon from the pomeron-odderon and the pomeron-photon fusion. We calculate scattering amplitudes of these processes in the lowest-order approximation and in the framework of k(perpendicular to) factorization. We present estimates of cross sections for the kinematic conditions of the Tevatron and of the LHC. [less ▲]

The transcription factor NF-kappaB is critical for the induction of cancer, including adult T-cell leukemia, which is linked to infection by human T-cell leukemia virus type 1 and the expression of its regulatory protein Tax. Although activation of the NF-kappaB pathway by Tax involves its interaction with the regulatory subunit of the IkappaB kinase (IKK) complex, NEMO/IKKgamma, the mechanism by which Tax activates specific cellular genes in the nucleus remains unknown. Here, we demonstrate that the attachment of SUMO-1 to Tax regulates its localization in nuclear bodies and the recruitment of both the RelA subunit of NF-kappaB and free IKKgamma in these nuclear structures. However, this sumoylation step is not sufficient for the activation of the NF-kappaB pathway by Tax. This activity requires the prior ubiquitination and colocalization of ubiquitinated Tax with IKK complexes in the cytoplasm and the subsequent migration of the RelA subunit of NF-kappaB to the nucleus. Thus, the ubiquitination and sumoylation of Tax function in concert to result in the migration of RelA to the nucleus and its accumulation with IKKgamma in nuclear bodies for activation of gene expression. These modifications may result in targets for the treatment of adult T-cell leukemia. [less ▲]

Twelve cattle were divided into 2 groups. The first was intranasally co-infected with 2 strains of infectious bovine rhinotracheitis virus (Bovine herpesvirus 1; BHV 1): the thermosensitive vaccine strain IBR/ts RLB106 and a Belgian field isolate IBR/Cu5. Reactivation of BHV 1 was induced by dexamethasone treatment 2 months later and again 5 months later for 3 animals that only reexcreted small quantities of virus during the first dexamethasone treatment. The second group was intranasally infected with IBR/Cu5. Two months later, an attempt to reinfect this group with IBR/ts RLB106 failed. Four months after the primary infection, these cattle were treated with dexamethasone. Except after reinfection and at the beginning or the end of the (re)excretion periods, excreted and reexcreted viruses replicated at 35, 37 and 40 degrees C, indicating the presence of the wild-type virus. Only one isolate, out of 116 cloned from the nasal exudates collected during the excretion and reexcretion periods, expressed the thermosensitive phenotype. This isolate was characterized by its mean plaque size as the IBR/ts RLB106 strain. The epizootiological significance of these findings is discussed, with emphasis on the weak spreading capacity of the ts vaccine strain and the possibility of emergence of recombinant viruses.
