This paper outlines the first permanent inventory carried out since the beginning of 1994 for monitoring and updating the forest resources in the Walloon region of Belgium (covering about 530.000 hectares of forests). The so-called inventory is based upon a systematic sampling design which takes into account 1 plot to 50 ha (grid of 0,5 x 1 km). The main objectives are : to continuously monitor the changing situation of forest resources and focus attention on the wooded production, availability and probable trends in the future, to assist the formulation of the medium and the long-term development plan of the forestry sector, to provide information for long-term planning, control and improve general forest management programs. Methodological aspects are given concerning the survey design, the sampling units and the collection of data. The processing of data, the type and the presentation of expencted results are also briefly descriebed. Some recommandations concern the way which could be used in terms of organizational structure and logistical support. [less ▲]

Inhibition of growth of normal and human papillomavirus-transformed keratinocytes in monolayer and organotypic cultures by interferon-gamma and tumor necrosis factor-alpha.

The growth response of normal and human papillomavirus (HPV)-transformed cervical keratinocytes to interferon-gamma (IFN-gamma) and tumor necrosis factor-alpha was investigated in monolayer and organotypic raft cultures. The proliferation rates of monolayer cultures were assessed by [3H]TdR incorporation and fluorimetric DNA titration. The growth of keratinocytes in organotypic cultures was estimated by their ability to stratify on collagen rafts and by immunohistochemistry for Ki67 antigen expression. IFN-gamma reduced the DNA synthesis of normal and HPV-transformed keratinocytes in monolayer cultures and exerted a marked growth inhibitory effect in organotypic raft cultures. In control raft cultures, normal keratinocytes produced an epithelial sheet of approximately 10 cells in thickness that closely resembled normal cervical epithelium and was characterized by sparse Ki67 antigen-positive cells whereas HPV-transformed keratinocytes produced up to 15 poorly differentiated epithelial layers that were reminiscent of high grade cervical lesions seen in vivo and exhibited a full thickness Ki67 antigen expression. When normal and HPV-transformed keratinocytes were maintained in the presence of IFN-gamma, the epithelial sheet was reduced to a few cells in thickness and the density of Ki67 antigen-positive cells was decreased. A more pronounced growth inhibitory effect in monolayer and organotypic cultures was observed when IFN-gamma was associated with tumor necrosis factor-alpha Tumor necrosis factor-alpha alone reduced the DNA synthesis of normal keratinocytes but was significantly less effective than IFN-gamma to inhibit the growth of HPV-transformed keratinocytes. These results suggest that similar responses in vivo to regulatory molecules may play a role in the development of HPV-related lesions. [less ▲]

More than 1500 otter spraint samples have been collected in different aquatic habitats throughout the present geographic range of the otter in France. Prey remains were identified, the relative occurrence and abundance of each species was assessed and the biomass of each individual prey estimated. When available, data about the fish communities (size frequency- distributions, relative abundance) were compared with the diet of the mustelid. The main conclusions of the study are as follows: 1. The otter is mainly piscivorous but some other aquatic (crayfish) or semiaquatic preys (frogs, Natrix-snakes, some birds and mammals) are of major dietary importance in oligotrophic habitats. 2. The composition of the diet is determined by the local fish resources. The otter is an opportunistic predator, its diet varying greatly from one place to another. The diet can also change depending upon the season or upon some special circumstances such as frog or fish reproduction or strong prey-community changes. 3. Small fish are dominant in the diet. No size selection has been evidenced at least in the eel and in the cyprinid fishes. As far as the trout is concerned, it seems that the otter consumes preferably medium sized individuals. 4. The proportion of some prey species is lower in the diet than in the habitat. These are the more pelagic (bleak, sander, breams), rheophilic (dace, chub) or group-living species (minnow, roach). Bottom- (bullhead, eel, tench, gudgeon, barbel) or plant-living (rudd, pike) species are more frequent. [less ▲]
