The wild boar's diet is investigated in two forests of the Belgian Ardenne: the Nismes deciduous forest and the Transinne coniferous plantations. Two complementary approach are compared: analysis of faeces collected throughout the year and analysis of stomach contents during the hunting season only. The faeces analysis method allows to follow the diet seasonal variations but conceals the occurence of some feed and minimizes the ingestion of vertebrates and of artificial fodder. It results from both approaches that wild boars are opportunist and omnivorous with an obvious tendency to herbivory. The human influence, direct (artificial supply) or indirect (neighbouring cultivated open fields, forest and game management, enclosure, lot of disturbances), plays the leading part in determining wild boar's diet and its food search. As a whole, plant products from natural origin come in second place in its diet whereas other feed always remain occasional, with the exception of acorn and beech mast when superabouding. A few suggestions for reducing wild boar's damage to crop and forests close the paper [less ▲]

Besides the hGH-N gene, which codes for the pituitary 22 and 20K GH variants, the human genome contains a second GH gene, namely the GH-V, which has been thought to be silent. We recently discovered a placental variant of human growth hormone (hPGH), which appears in maternal serum at mid-pregnancy and which rises in concentration thereafter to term. As hPGH and GH-V proteins display very similar characteristics, including a high affinity for hepatic GH receptors, they could be identical. To verify this hypothesis, we sought hGH-V mRNA in placenta. Hybridization experiments were performed between dot-blotted mRNA originating either from placenta or from one pituitary hGH secreting adenoma and synthetic polynucleotide probes corresponding to specific portions of the hGH-V or hGH-N gene sequences. The results indicate that the V gene is indeed expressed in the placenta and, at a very low level, in the pituitary adenoma. Therefore hPGH is most likely the expression product of the hGH-V gene.

Fifty six otter spraints were collected along three oligotrophic streams of Central Brittany, from 1982 to 1985. Pry items were identified, enumerated, and their size estimated, using the same criteria as those previousely used by Hallet (1977-1985) in her study of the diet of the Kingfisher (Alcedo atthis). Among the 251 prey items belonging to 11 taxa, small fish species such as the bullhead (Cottus gobio) and the minnow (Phoxinus phoxinus) were the most abundant. From the trophic point of view, however, their importance was rather negligible, since their biomass made up 10 % only of the overall biomass ingested. Large prey, such as trout (Salmo trutta), birds and mammals, made up the bulk of the otter diet in this area. [less ▲]

The observation of a troop of baboons (Papio Anubis) at the Akagera national Park, from April to July 1985, allowed gathering data on social interactions between and within various age-sex catégories considered. The troop could be rapidly approached by the observer thanks to episodic food distribution. The indirects followings of that method are commented upon. besides the description of the interactions, we tried to examine the recurrence of some interaction sequances that modulate the current interpretation of these behaviors when separately considered. The importance of the spatial context and the impact of vocalizations is emphasized in the analysis of the social behaviors and bonds meaning [less ▲]

An introduction to the theory of nonradial modes of oscillation is presented. Evidence for such pulsations can be found in numerous variable stars. New results are presented for stars varying with periods of the order or longer than the hour, namely Beta Cep stars, line-profile variable stars, and WR stars. [less ▲]
