Lake Noukoué in southern Benin, is heavily exploited fishery, but it is also inhabited by numerous piscivorous birds, escpecially kingfishers. This study considers the similarity between the diet of kingfishers and fish available on the local market between mid-February to mi-May 1999, durng a low water level preriod. Excretory pellets were collected on the top of breeding banks and inside brood chambers. The diet was determined by comparing the bones recovered from the pellets with a reference collection. Eighteen prey categories were recognised in the 1099 diagnostic items. Kingfishers preyed mostly on cichlids (Sarotherodon melanotheron Rüppell and Hemichromis fasciatus Peters), clupeids (Ethmalosa fimbria (Bowdich)), eleotrids (Kribia sp.) and Hyporhamphus picarti (Val.). Prey size of H. fasciatus ranged from 22 to 73 mm (46.4 +/- 11.6 mm) and S. melanotheron from 24 to 65 mm (44 +/- 9.2 mm). The compositionof the diet varied depending on time and location. Overlap with marketed fish is limitid to S. melanotheron. [less ▲]

We sequenced 965 base pairs of the mitochondrial DNA cytochrome b from 102 woodmice (Apodemus sylvaticus) collected from 40 European localities. The aims of the study were to answer the following questions. (i) Did the Mediterranean peninsulas play a role as refuge for woodmice? (ii) Is genetic variability of A. sylvaticus higher in the Mediterranean region compared with northern Europe? (iii) Are the patterns of the postglacial colonization of Europe by woodmice similar to those presently recognized for other European species? The results provide a clear picture of the impact of the Quaternary glaciations on the genetic and geographical structure of the woodmouse. Our analyses indicate a higher genetic variability of woodmice in the Mediterranean peninsulas compared to northern Europe, suggesting a role of the former as refuge regions for this small mammal. An original pattern of postglacial colonization is proposed where the Iberian and southern France refuge populations colonized almost all European regions. The Sicilian population appears to be very differentiated and highly variable. This emphasizes the importance of this island as a 'hot spot' for the intraspecific genetic diversity of the woodmouse. Finally, woodmice in North Africa originated from southwestern Europe, most probably as a result of a recent anthropogenic introduction. [less ▲]

The aim of this study was to determine the habitat use of the last important Belgian colony of Rhinolophus hipposideros, Bechstein, 1800, one of the most endangered bat species in Europe. During 71 evenings from April to August 1998, ultrasound detection was performed and, in late August, a female horseshoe bat was caught and fitted with a radio transmitter. The results showed that hedgerows and woodlands with bushes and coppice are key foraging habitats. They also highlight the importance of the presence of a network of wooded elements connecting the maternity roost with the foraging areas. To assure long-term protection of this colony, strong habitat conservation measures should be taken in a radius of up to 1-2 km around the roost. [less ▲]

We have sequenced 965 base pairs of the mitochondrial DNA cytochrome b from 102 woodmice (Apodemus sylvaticus) samples collected from 40 European localities. The aims of the study were to answer the following questions: i) Did the Mediterranean peninsulas play a role as a refuge for small mammals? ii) Is the genetic variability of a small mammal like A. sylvaticus higher in the Mediterranean regions as compared with northern Europe? iii)Is it possible to find patterns of postglacial colonisation of Europe other than those presently recognised ? Sequence data were analysed using Distance and Maximum Parsimony phylogenetic reconstruction methods. A minimum spanning network was also calculated. Population genetic structure was determined by analysis of molecular variance (AMOVA). A "mismatch distribution" analysis was also performed to estimate the patterns of expansion. The results provide a clear picture of the impact of Quaternary glaciations on the genetic and geographic structure of the woodmouse. Analyses indicate a higher genetic variability for the woodmouse in the Mediterranean peninsulas as compared to northern Europe and the role of these peninsulas as refuge regions for small mammals. A new pattern of postglacial colonisation is also proposed where the Iberian and southern France refuge populations colonised almost all the European regions. The Sicilian population appears to be highly differentiated and highly variable. This result emphasises the importance of this island as a "hot spot" for the intraspecific genetic diversity of the woodmouse. Finally, populations of this species in North Africa originated from south-western Europe and are probably the result of a recent anthropogenic introduction. [less ▲]

The stomach contents of 40 great cormorants shot during "regulation" operations in the Pas-de-Calais have been analysed. Eight stomachs were empty and 426 fishes belonging to 15 species were recovered in the others. The dominant prey is the roach. Other regular prey are the common bream and the perch. Other fish (Salmonids, pike, pikeperch, ruffe, rudd, lamprey) appear in less than 5 stomachs. Most of the prey are small sized fish, less than 12 cm (total length). The biomass of 80% of the preys is less than 20g. However, the role of the greater fish in the diet must be emphasized: those weighing more than 200g (1% in numbers) reprensent 20% of the ingested biomass. [less ▲]

In south-west Belgium, the breeding of the kingfisher was monitored for more than 10 years. During this period, 158 banks were regularly surveyed. Alterations or potential threats were identified: natural erosion, cattle trampling, disturbance from kayak-riders or anglers and, last but not least, consolidation works. Only 56 banks (35.4 %) can de considered as "safe". However, since the recent (2001) legal restrictions about the navigation on small rivers, 12 more banks are now safe too. Cattle trampling appears as the main threat (55 sites). However, the enforcement of the law regulating the fences along the rivers could easily solve the problem. Nineteen banks were completely destroyed for different purposes: navigation, road retaining walls or simply anti-erosive measures. Most of these works were undertaken along the river Meuse, the best nidification habitat of the area. (11 photos) [less ▲]

The diet has been studied in 3 zones where two species, polecat and European mink, cohabiting. Feces were collected at the animals resting-place with radio transmitters. The diet of mink is electic : mammals (Ondatra, Arvicola sapidus, rats…), birds (duck, rallids…), frogs and toads and fish. The polecat eats mammals (rabbits, hares and small mammals), some birds and reptiles, plenty toads. The trophic similarity is fairly low. In fact, for two weasels , individual and seasonal variations are very important. [less ▲]
