Full textArctic cod (Boreogadus saida) plays a crucial role in the marine Arctic ecosystem. For the first time, the hatching season, and the early growth and survival of Arctic cod are described for the Laptev Sea. The hatching season was early and long (January to July) compared to the North Water and Northeast Water Polynyas (May-June). Length at age was 4 mm longer in 2005 (a year of low ice cover) than in 2003 (heavy ice cover). Larval survival could depend mainly on ice conditions, particularly on the extent and duration of opening of winter polynyas, a key feature of the Laptev Sea that shows strong interannual variations. In particular, the absence of surviving larvae for the period of January to mid-March 2003 coincided with the absence of polynya in the study area.

Full textThe rainforest of French Guiana is located in the Amazonian region, which is a hotspot of biodiversity, thus leading to several issues about conservation in tropical forests. Knowledge of the age and growth rate of trees is essential to understand the dynamics of these ecosystems. However, due to the lack of winter conditions it is difficult to read the story in the wood of these tropical forests. In the topic of functional anatomy, this thesis intends through different approaches i) to monitor the cambial activity of four tree species during two years sampling micro-cores, ii) to make a dendrochronological study on a Guyanese species iii) to use the variation of the isotopic signature as a marker of growth (or history) and iv) to test air pollution following launches of the Ariane rocket as markers of growth. The bi-monthly review of cambial activity showed that all trees have almost alternating rest and high activity of cambium in both years. These downturns have been more pronounced in Parkia nitida (deciduous), Parkia velutina (deciduous) and Schefflera morototoni (evergreen). We observe periods of cambial activity downturn in two deciduous species as well as in an evergreen species. There is no universal pattern of connections in pairs between rainfall intra-annual phenology of leafing and cambial activity although strong similarities exist in each case between two species for a given association. The dendrochronological study in Parkia nitida highlights the presence of distinct annual growth rings. The limit is characterized by a thin band of marginal parenchyma containing numerous crystals of calcium oxalate. At tree scale, secondary growth is homogeneous and relatively synchronous within individuals of this species in the same location. However, the influence of tested climatic parameters, such as temperature and precipitation on the annual radial growth, is low over the considered period. The first two studies showed that, in the environment of French Guiana, marked annual seasonality of rainfall does not affect in a strong way the behavior of the trees. Nevertheless, those rainfalls have an influence either on leafing, flowering or cambial growth. Other methods of marking growth (i.e. isotopic and chemical) intended require further investigations. Axial parenchyma represents a high average percentage in the wood of rainforest species: it could be important to investigate more precisely its role as accumulators of potentially useful substances involved in wood defense against borers. The evolution throughout time (periodicity, chemical aging) of defense mechanisms in woods is an interesting way for dendrochronology

Full textArctic cod (Boreogadus saida) is widely distributed in circumpolar Arctic seawaters and plays an important role in transferring energy from lower trophic levels to higher predators in the Arctic marine food web. To limit vulnerability of young Arctic cod to predation and/or cannibalism at the end of short Arctic summers, reproductive strategy of this key species has evolved to reach the largest pre-winter size of cod juveniles. Two adaptative mechanisms strongly influence variability in survival of juvenile Arctic cod in relation to environmental conditions: the hatching season and early growth. In a changing Arctic climate that exhibits interannual variations and strong seasonality, hatching and growth dynamics of Arctic cod urgently need to be address. In this study, we first determined the individual hatch dates of juvenile Arctic cod sampled in southeastern Beaufort Sea during fall expeditions over a five-year period (2002-2006) and from April to August in 2004. The results suggest the existence of two distinct populations of larval Arctic cod in the study area. First, an inshore population that hatches early in winter (January to March) in the thermal refuge (T ≥ -0.47) provided by the estuarine waters of Mackenzie Lake extending under landfast ice. Second, an offshore population of delayed hatching (April to June) that coincide with the ice break-up and the vernal onset of biological productivity on the Mackenzie Shelf and in the Amundsen Gulf. The interannual variability (2002-2006) documented in hatching patterns of juvenile cod results from the relative importance of early-winter hatchers surviving each year and is partly related to variations in dominant environmental factor in the habitat. Overall, this study documents the reproductive strategy of Arctic cod in southeastern Beaufort Sea that aim to maximize size of juvenile at the onset of their first winter under the ice.
