    Description / Table of Contents: Chapter 1: General information on large camelids in the world: Origin, taxonomy, biodiversity, and new settlements -- Chapter 2: Anatomical features of large camelids -- Chapter 3: Physiology of large camelids: Life cycle, adaption to ecosystems, and reproduction -- Chapter 4: The physiological basis of large camelid lactation, digestion, and nutrition -- Chapter 5: Technical management of a camel farm with a focus on dairy: Breeding and young animal rearing, milking, and feeding -- Chapter 6: Animal health management and veterinary practices in a camel farm -- Chapter 7: Economic management of a dairy camel farm -- Chapter 8: Camel products and services: From dairy-, meat and non-food products to riding and transport, including slaughter.
    Abstract: This practical guide is intended for all actors in the sector who work with large camelids, whether in breeding, technical advice or veterinary care. It successively describes the general aspects of the species, the physiological bases of reproduction, lactation and feeding, the main production processes, and health and hygiene management in camel breeding. Chapters on slaughter, important camel products and their processing complete the volume. Large camels (camels and Bactrian camels) are domestic animals that are increasingly used in Western countries, as well as in Africa and Asia, for tourism, sport, and production of milk, meat, and wool. In addition, camel husbandry systems are changing, taking a greater share of sedentary systems, specializing in breeding, and intensifying production. At the same time, many veterinarians and breeders are not familiar with the animal, its needs, physiology, diseases, and management, which is often based on practices introduced for cattle and proving ineffective. This work is a practical aid for all interested readers who want to embark on the adventure of working with large camelids in a cultural context where they are not yet a dominant element of the agricultural landscape. The numerous photographs and drawings that support the text make it a unique and entertaining read.

    Diel locomotor activity of brook charr, as determined by radiotelemetry (1996)

    Notes: Locations by radiotelemetry during eight 24–h sampling periods in 1991, 1992, and 1993 were used to evaluate the diel activity patterns of adult brook charr Salvelinus fontinalis in two lakes of the Laurentian Shield (Québec, Canada). Based on the minimum distance travelled between two consecutive locations, adult brook charr were more active at dusk and at night than during the day. During daylight periods, individual fish displayed strong site selection, remaining in the same area along the shore from day to day. The fish left their inshore position at dusk, were highly mobile during the night, and returned to their focal point at sunrise, exhibiting diel homing behaviour. These results are supported by an increase in gillnet captures of adult brook charr in Lac Melchior at night. Data obtained by gillnet fishing in lakes Bondi and Simpson showed that juvenile (1+) brook charr were active throughout the diel cycle and that young-of-the-year were active mainly during the day, suggesting that there is an ontogenetic change in the diel activity of brook charr. Despite its limitations (restrictions on the number and size of tracked individuals, post-manipulation mortality, lifetime of transmitter battery), radiotelemetry allows for collection of multiple behavioural observations (distances travelled, instantaneous activity, site selection and homing) during the activity cycle of individual fish, and thus provides a finer degree of spatial resolution than alternative methods such as gillnetting.

    Notes: The abundance, growth, spatial distribution, and feeding habits of five allopatric brook charr, Salvelinus fontinalis, populations (young-of-the-year, 0+ juveniles; YOY) were compared with five other populations living sympatrically with white sucker, Catostomus commersoni. The study was made in oligotrophic lakes of the Laurentian Shield (Québec, Canada) during three sampling periods in 1989 (July, August and September). The abundance of YOY charr was significantly higher in allopatric than in sympatric populations (45·3 ± 3·8 vs 3·4 ± 3·8 fish/lake caught in 1773 m2 of gillnets; P〈0·005). The mean length of YOY charr did not differ among allopatric and sympatric populations at each sampling period; July: 60·2 ± 3·0 vs 60·0 ± 4·5 mm; August: 61·9 ± 4·5 vs 63·2 ± 4·1 mm; September: 77·9 ± 8·7 vs 77·3 ± 7·8 mm respectively. Horizontal distribution of allopatric YOY charr did not differ from that of sympatric charr, 65% of the fish being captured within the first 2 m depth and the rest between 2 and 7 m depth. In contrast, the vertical distribution of allopatric YOY charr from both communities was significantly different; 81% of allopatric charr were captured within 0·5 m from the substrate compared to 64% for sympatric charr (P〈0·001). Differences in vertical distribution of the fish were related to differences in diet; allopatric charr fed mainly on benthic and large planktonic organisms whereas sympatric charr fed less on these organisms and more on terrestrial organisms. In the lake where YOY charr were most abundant, individuals were spatially segregated into two groups; one ‘littoral’, found in 0–2m depth, and one ‘profundal’, found in 3–6 m depth. Growth, condition, and feeding habits of charr from the two groups were different, especially during the last sampling period.

    The Impact of Profit Sharing on the Performance of Financial Services Firms* (2005)

    Details

    Notes: abstract  Relying on macro theories (agency and organizational control) as well as micro theories (goal setting and expectancy), this study investigates the impact of profit-sharing plan (PSP) adoption on the value creation process of financial services firms. The study relies on a comprehensive methodological approach that is both quantitative, with a dual cross-sectional/longitudinal (pre-post) design that compares PSP adopters with a control group of PSP non-adopter firms, and qualitative through interviews with some adopting firms’ managing directors. Results show that firms adopting a PSP enhance their profitability in comparison to both their own prior performance and to firms that are not adopting a PSP. Results also show that the adoption of a PSP: (a) positively influences only profit drivers that are under employee control; and (b) is more likely to have a long term, positive impact on external profit drivers than on internal profit drivers. Qualitative data from field interviews corroborate and enrich these quantitative findings.

    Water temperature, light intensity and zooplankton density and the feeding activity of juvenile brook charr (Salvelinus fontinalis) (2002)

    Notes: SUMMARY 1. The objective of this study was to evaluate the effects of zooplankton biomass (as a measure of density), fish biomass, light intensity and water temperature on the attack rate and swimming characteristics (i.e. swimming speed and angle of turn) of juvenile (1+) brook charr (Salvelinus fontinalis) in field enclosures. We used a portable underwater camera system in a series of pelagic enclosures to quantify the feeding behaviour of brook charr over a gradient of natural conditions.2. In simple linear or non-linear regression models we found (i) that attack rate and angle of turn were positively related to water temperature, (ii) that attack rate and swimming speed were positively related to zooplankton biomass and light intensity and (iii) that attack rate was positively related to swimming speed. In multiple regression models, fish biomass, light intensity and variance of the angle of turn accounted for 87% of the variation in attack rate. Light intensity and water temperature accounted for 86% of the variation in swimming speed. Fish gut fullness and attack rate accounted for 83% of the variation in the variance of the angle of turn executed by fish.3. The increase in the number of attacks as zooplankton biomass increases conforms to the general positive functional response observed in other fish species. Our results also support the hypothesis that swimming speed increases with prey biomass. We did not observe a plateau in attack rate as zooplankton biomass increased. As our experiments were performed under natural biotic and abiotic conditions, factors other than zooplankton biomass might affect or limit this response, such as water temperature and light intensity.4. Because zooplankton biomass was correlated with water temperature and light intensity, it was not possible to evaluate the independent contribution of these factors on the attack rate and swimming characteristics (swimming speeds and angle of turn) of brook charr. However, this study highlighted the impact of these factors on the feeding behaviour of juvenile brook charr when feeding in the pelagic habitat under natural conditions, and their importance in future models of optimal foraging and fish habitat quality.

    Genetic and morphological variation between two forms of lacustrine brook charr (1999)

    Notes: Genetic data suggest that the littoral and pelagic forms of brook charr Salvelinus fontinalis in Lake Bondi are two populations with partial reproductive isolation and non-random mating. Genetic differentiation between the two groups was supported by differences in allele frequencies and by deviation from Hardy-Weinberg equilibrium when the two groups were pooled; no such deviation was observed when fish were divided into littoral and pelagic groups. In contrast to Lake Bondi, no clear evidence of genetic differentiation was observed in Lake Ledoux. Discriminant function analyses of morphological characters support the existence of littoral and pelagic groups in Bondi and Ledoux Lakes. In Lake Bondi, the two groups differed significantly in two shape variables (pelagic fish had shorter dorsal fins, and longer body length posterior to the dorsal fin than littoral ones) whereas in Lake Ledoux, the groups differed in four shape variables (pelagic fish had shorter pectoral fins, shorter dorsal fins, and a shorter and higher caudal peduncle than littoral ones). Discriminant analyses of these characters were effective in reclassifying fish into their appropriate groups in both populations, with an efficiency of 78% for juveniles in Lake Bondi and 69% for adults in Lake Ledoux. Differences in morphology between the two forms are consistent with adaptations required to forage in each zone, i.e. benthic form in the littoral zone and planktivorous form in the pelagic zone.

    Individual variations in habitat use and morphology in brook charr (1997)

    Notes: 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.

    Notes: River discharge and water temperature are frequently cited as controlling the upstream migration of adult salmonids to their spawning areas. The results of earlier studies on the effect of these environmental factors were examined. The statistical methods employed in some of these studies failed to consider the serial correlation often found in migration time series. To assess the effects of discharge and temperature on the migratory activity of the landlocked Atlantic salmon (ouananiche, Salmo salar), 12 years of data on spawning migrations in the Mistassini R., Quebec, Canada, were analysed and the results obtained by ordinary least squares regression and time series regression were compared. In six of the 12 years, upstream migratory movement was related negatively to changes in river flow, suggesting that fish favour falling water phases for ascent. Water temperature appeared to have little effect on migratory movement. The mean body size of migrating fish decreased significantly throughout the summer; early migrants were on average 11.4% larger (mean fork length 522mm) than late migrants (469 mm). Larger, 3-lake-year salmon migrated 7.2 days earlier than 2-lake-year salmon. Because the residuals from ordinary regression exhibited strong autocorrelation, time series regression was more appropriate than ordinary regression for the analysis of migration time Series.
