The specific objectives of this study were to determine if there is individual specialization in habitat use by lacustrine brook charr Salvelinus fontinalis and if so, if specialization is related to fish morphology. Localizations of 28 brook charr equipped with thermosensitive radiotransmitters were recorded during three summers (1991, 1992, and 1993) in two lakes of the Mastigouche Reserve (Québec, Canada). Fifty per cent of the fish were found mainly in the benthic zone (hereafter benthic individuals), 18% in the pelagic zone (pelagic individuals), and 32% travelled regularly between the two zones (generalist individuals). The observed interindividual differences in habitat preference were related to differences in body morphology and coloration: (i) the pectoral fins of benthic and generalist individuals were significantly longer than those of pelagic ones; and (ii) the coloration of the lower flank of benthic and generalist individuals was silver-grey while that of pelagic individuals was red. The results of this study suggest that brook charr inhabiting oligotrophic lakes of the Canadian Shield exhibit trophic polymorphisms, where some individuals are specialists better adapted to feeding in the littoral zone whereas others are specialists better adapted to feeding in the pelagic zone. The potential for reproductive isolation between the two morphs is discussed. 1997 The Fisheries Society of the British Isles 1997 The Fisheries Society of the British Isles

During the past year the collection has been greatly improved and is now without doubt the m ost representative in the world. Some 600 birds of 101 species and subspecies are to be seen in the various enclosures at the New Grounds. Representatives o f 20 of these forms are, or were when they arrived at the New Grounds, the only living specimens o f their kind in this country. This collection, therefore, offers a unique opportunity to the student o f evolution Plum ed or E y ton's Whistling D uck and Systematics. It is also of great value to the study o f behaviour and to many specific researches in bird pathology, parasitology, serology, etc. And to those who have no specialised interest in this direction, it offers a lively and beautiful sight as the birds cluster round at feeding time.

reasonable comparisons over time. 3. With the planned wetland/beaver dam improvement, consideration should be given to monitoring prior to the beginning of this project, during the project, and after the project to determine success. This sampling should focus at the base of this sub-watershed of Sucker Brook (Site 7) and extend over several weeks during events and nonevents. The greater the number of samples taken the better able we are to evaluate its outcome. 4. If management or remediation efforts are attempted at other locations in the watersheds, an effort similar to item 3 should be considered as part of an adaptive management approach.

Species information Characteristics Adults are elongate in shape and cylindrical in cross-section (Figs. 1-2). Eye small. Seven branchial openings (Fig. 3). The body lacks scales and is divided into vertically oriented myomeres (muscle segments), usually between 50-52 (range 47-56) myomeres between the most posterior branchial opening and cloacal slit (Fig. 2). Two dorsal fins separated by a shallow notch with the posterior dorsal fin slightly taller than the anterior. A low fin fold connects the dorsal fins with a rounded caudal fin. Shallow anal fin' fold. Up to 180 mm total length. 3,
