| Indigenous Arctic and Subarctic communities currently are facing a myriad of social and environmental changes. In response to these changes, studies concerning indigenous knowledge (IK) and climate change vulnerability, resiliency, and adaptation have increased dramatically in recent years. Risks to lives and livelihoods are often the focus of adaptation research; however, the cultural dimensions of climate change are equally important because cultural dimensions inform perceptions of risk. Furthermore, many Arctic and Subarctic IK climate change studies document observations of change and knowledge of the elders and older generations in a community, but few include the perspectives of the younger population. These observations by elders and older... |

| This study was the first to be undertaken since 1901, since when natural and industrial changes had occurred to affect the habitat. Observations are reported here for the banks of the north and south shores, using certain points as reference. Features of the 2 shores are described, and an inventory given of the fauna of the banks. Hydrozoan Cnidaria, Bryozoans, Annelids, Molluscs, Crustacea and fish are listed with notes, and particular attention is given to the crabs found (Rhithropanopeus harrisii tridentatus). The monthly distribution of crab sizes and sexes is given, and the species of animals found in association with crabs is shown to vary according to the site studied. The percentage of female crabs found to be fertile each month was investigated,... |

| La campagne 2018-2019 est la sixième campagne consécutive du MYTILOBS après stabilisation des procédures et des protocoles. Au cours de cette campagne, une action supplémentaire visant à caractériser la qualité cyto-génétique des cheptels a été adossée au réseau. Le suivi des 2 points de Roulières et de Boyard a dû être abandonné, et un lot de moules de 2 ans a été ajouté au cheptel sentinelle pour le suivi des mortalités qui l’ont affecté. Les résultats de l’action d’observation mettent en évidence des mortalités toujours très présentes sur les sites du réseau qui avaient été les plus affectés au cours des années précédentes (principalement, la Baie de Bourgneuf et les secteurs d’élevage des Pertuis Charentais). La croissance des moules s’est avérée... |

| La campagne 2017-2018 a été caractérisée par une augmentation quasi-généralisée des mortalités par rapport à l'année 2017, sans atteindre toutefois les taux de mortalités observés en 2014 ou 2016. Dans les Pertuis Charentais, les épisodes violents de mortalité observés auparavant ont ainsi laissé la place à des mortalités chroniques, quasiment impossibles à détecter dans les élevages mais bien mises en évidence par le protocole d'observation. Les mêmes signaux sont également observés sur la côte ouest de la presqu'île du Cotentin depuis quelques années. Sur ces sites, les taux de pertes cumulés étaient compris entre 17 et 44% au mois de septembre. En Vendée, des épisodes intenses et brutaux de mortalité ont été observés comme au cours des années... |

| Le réseau ECOSCOPA, co-financé par la DPMA, a pour objectif de développer un outil permettant de mesurer, à plusieurs échelles, des paramètres environnementaux et biologiques en lien avec la croissance et la survie d’huîtres creuses en élevage. Sur l’année 2015 et afin de préparer de façon concertée ce projet, il a été proposé dans un premier temps de renforcer la synergie existante entre les réseaux RESCO et VELYGER afin de disposer d’un suivi proactif du cycle complet de production de l’huître (incluant le captage, la croissance, la reproduction, les éventuelles mortalités) à partir d’animaux communs sur différents sites ateliers, en lien avec l’acquisition de descripteurs environnementaux et physiologiques susceptibles d’influencer chacune de ces traits... |

| The scientific cruise Observhal98 took place in Biscay Bay, May 14 to June 6, 1998, with the submersible Nautile operated from the research vessel Nadir. The goal was to make direct underwater observations on fishes and invertebrates of commercial interest, on the environment in which they live and on the impact of fishing gears. A total of 22 dives, 2 to 5 hours long have been operated, ten by depth 1800 to 1000 m, three by 500 to 200 m, seven by 80 to 200 m and two in the water column. An in situ technic have been developped and operated from the submarine, with the aim of studying the growth scheme of deep water fishes. Specimen of Hoplostethus atlanticus and Trachyscorpia cristualata have been caught, anesthetised, injected with vital coloring and... |

| The present paper constitutes an introduction to taxonomic methodology. After an analysis of taxonomic practice, and a brief survey of kinds of attributes, the paper deals with observation, description, comparison, arrangement and classification, hypothesis construction, deduction, model, experiment, abstraction, and synthesis. The methodological aspects of the species-concept and of biological classification are dealt with in two final sections. |

| Scandals in the food production industry have caused an uncertainty about quality and innocuousness of food for many consumers. This resulted in a strong risk perception of consumers at the point of sale. The direct marketing of products by farmers can be an important way to strengthen consumer confidence. In this contribution, buying behaviour is examined by an observation and a following interview. We develop an econometric model about the number of bought products and the proposition of marketing strategies which can be recommended to farmers involved in direct marketing. |

| Adequate habituation of free-ranging subjects is essential for any field study, but is generally unsystematic. Here, attempts to habituate three titi monkey (Callicebus coimbrai Kobayashi & Langguth, 1999) groups are described, and factors determining the effectiveness of the process are discussed. The "relentless pursuit" approach was aided by playback recordings of vocalizations but only one group was habituated adequately. Average contact in 13 encounters with group 1 was just over one minute, whereas in 32 encounters with group 2, it averaged 3,5 minutes (maximum = 22 minutes). Group 3 was more tolerant of observers, and was considered fully habituated by the seventh encounter. The factors determining this disparity remain unclear, although... |
