The distribution and the present status of the polecat, stoat and weasel in Belgium are presented. At this time, these species are widely distribution all over the country and it seems that they aren't shortly threatened. Some original data on mortality causes are briefly discussed. Undoubtely, it appears that the major ones are trapping and killing by gamekeepers and road casualties, both accounting for more 70 % of the polecat's (n=96) and stoat's (n=45) losses and for 63% (n=101) of the weasel's ones. No information is available about possible death cases due to ingestion of poisoned baits. Poisoning, trapping and hunting are no longeur allowed in the northern part of Belgium (Flanders) but they are permitted in the southern part (Wallony) all over the year without any limitation (except for poisonning). With the legal protection of these animals in prospect, their dietary habits and their main behavioural and demographical characteristics are reviewed. [less ▲]

In close connection with the otter conservation, the author rewiews what happened in Belgium since the publication of the report on threatened mammals in Wallony. Despite several deputies interventions in the Regional Council of Wallony, it appears that the legal status of the otter remained unchanged. Field research is still in progress and new occupied sites have been discovered. Unfortunately, hydraulic works are planned and some of them already realized in the river Ourthe, a tributary of the river Meuse, namely in a proportion still inhabited by a relictual otter population.

Next to a short analysis of the sexual interactions and the relative importance of the stimulation kinds performed with each behaviour pattern, we analyse the observed behavioural sequences in courtship and mating behaviour of three chelonian's species: Pelomedusa s. subrufa, Sternotherus minor and Kinixys belliana nogueyi. The study of the behavioural sequences emphasizes the great fluctiation between the exhibited behaviour patterns and specifies the means leading to the female's stabilization. The sexual behaviours (knowed from this study or the litterature) of P.s.subrufa, S. minor, K. belliana nogueyi, Geochelone carbonaria, Testudo g. graeca, Emys orbicularis, Chrysemys scripta elegans, Chemmys nigricans and Meosemys grandis were submitted to a discriminant analysis to establish certain phylogenetic relations by use of behavioural criteria. We emphasize here the difficulties of the interpretation of this lethod. However, we establish a relative ratification of the phylogeny founded on morphological characters. [less ▲]

The Belgian population of the badger have suffered a severe decline during the two past decades. More thanone hundred burrows have been screened in order to define their characteristics. The data have been submitted to a multivariate analysis, allowing to isolate the main criteria guiding the habitat choice. The badger is supposed to be able to recolonize most of the sites from where it has disappeard il the persecutions it has to face were to come to an end. [less ▲]

Correspondence analysis is used to study the variations of the diet of the Barn owl in the eastern part of the Pyrenees, and their relationships with the various vegetation zones of the area. Nineteen samples of owl pellets (18561 prey items) were collected, together with information on the altitude, climate, vegetation and land-use of the sites where pellets were gathered. Mus spretus is a typical eumediterranean species. Pitymys pyrenaicus, Microtus arvalis, Clethrionomys glareolus, Sorex "araneus" and S. minutus are conspicuously absent. Pitymys duodecimcostatus, Suncus etruscus and Crocidura suaveolens cannot be considered as "indicator species" of the mediterranean biome. These small mammals take advantage of some man-made environmental changes to enter areas well outsite the limits of the mediterranean bioclimate: e.g. cultivated fields with deep soils for Pitymys and dry-stone walls for Crocidurine shrews. The strong correslation existing between ecoclimatic factors and prey selection emphazises the opportunistic nature of barn owl's predatory behaviour. The use of fossil pellets as an indicator of past environmental cnditions of a given area is amply justified [less ▲]

After de Selys Longchamps (1842), the otter in Belgium was a widespread species along all the full of fish rivers and was regarded as a pest namely in the fishponds of the Campine. This animal becomes extremely rare now: in Wallony, we only recorded one place where cubs are reared every year. The main reasons for this steep population decrease are well known: i. the otter has been systematically destroyed by hunters, fishermen and trappers who were receiving bounties till 1965 ! ii. the water pollution and the radical changes of the rivers physical characteristics (dredging, straightening and reshaping the river beds or banks) have had disastrous effects on fish, the main food resource of the otter. iii. a lot of previous suitable habitats have been destroyed due to for example draining of swamps and marshes and concreting the river banks. A comprehensive study of the fish populations in Wallony reveals that a small number of streams are still inhabited by relatively undamaged fish communities. Most freshwaters are polluted at different levels, some in a chronic way, others irregularly and many of them have been damaged by hydraulic works so becoming unsuitable for the otters because of a drastic reduction of their fish biomass. In such circumstances it seems likely that we cannot be really optimistic as far as the otter's future in our country is concerned. The last places where otters can still be found today must be inconditionnally protected against every disturbance of whatever type; but those measures will only help if a strong program is undertaken without delay intending to improve the water quality. An educational campaign is also urgently needed. [less ▲]

Fossif remains of hamsters from the late Pleistocene were found in Belgium. But this animal seems to have disappeared between that period and the mid 19th century. When again registrated it was only found in the "le pays de Herve" between Herve and Limbourg. Then it progressively reached the center of Brabant, the westernmost part of its range. In the early 20th century, hamsters were so numerous that people were going through an aradication campaign to prevent the damaging of their crops. However, we believe that the major reasons of its present scarcity were the sound modifications of the agricultural technology and landscape (mechanization, regrouping of land, deep ploughing after the harvest...) Hamsters live now in Hesbaye, the Pays de Herve and in the east of Brabant. But they are so few that it appears to take some conservation measures [less ▲]
