Data assimilation for stochastic ocean models

Assimilation de données pour des modèles océaniques stochastiques Cette thèse explore différentes techniques d’assimilation de données pour des modèles océaniques, et en particulier les modèles stochastiques. La méthodologie stochastique utilisée s’appelle l’incertitude de position (LU en anglais) et vise à incorporer un caractère ...

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

Fisheries Oceanography, EarlyView.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

Journal of Fish Biology, EarlyView.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

Leaders' Functional Specialization and Responses to Institutional Shifts during Crises: Evidence from the Pandemic

Journal of Management Studies, EarlyView.
Abstract Prior studies on crisis management often highlight the adaptiveness of generalist leaders, whose diverse functional experiences allow for flexible and innovative responses. However, we propose that in situations where crises lead to abrupt shifts in dominant institutional pressures, leaders with specialized functional backgrounds potentially ...

Constructing Eco‐Responsible National Identities Through Collective Memory: Settler and Māori Histories of Environmental Change in Aotearoa New Zealand

Nations and Nationalism, EarlyView.
ABSTRACT A growing body of scholarship argues that collective memories of historical environmental change—formed and transmitted through museums, movies, novels, activist performances and other cultural texts and practices—can help nurture proenvironmentalism.

Rapid dehydration drives a nondiffusional drop in C3 photosynthesis that aligns with phosphate limitation

New Phytologist, EarlyView.
Schematic representation of the causal sequence through which rapid water loss imposes diffusive and nondiffusive restrictions on carbon assimilation. Summary Drought is an abnormally prolonged water deficit posing major challenges to plants. Stomatal closure has long been considered the primary factor limiting photosynthesis during the early stages of

Intra‐annual transfer of hydrogen and oxygen isotopic signals from water and sugar precursors to tree rings: Processes and mechanisms

New Phytologist, EarlyView.
Intra‐annual radial growth of beech and spruce in 2021 and 2022. Summary The oxygen (δ18O) and hydrogen (δ2H) isotope compositions of leaf and xylem water shape tree‐ring isotope baselines, while the fraction of sugars undergoing isotopic modification downstream of leaves (fO, fH) determines the dominant hydrologic signal.
