Global and Regional Marine Ecosystem Models Reveal Key Uncertainties in Climate Change Projections

open access: yesEarth's Future, Volume 13, Issue 3, March 2025.
Abstract Climate change is affecting ocean temperature, acidity, currents, and primary production, causing shifts in species distributions, marine ecosystems, and ultimately fisheries. Earth system models simulate climate change impacts on physical and biogeochemical properties of future oceans under varying emissions scenarios.

ASSEMBLY OF A METHODOLOGY FOR DETERMINATION OF MEMBRANE EFFICIENCY IN PRESERVED SHALES

open access: yesCT&F Ciencia, Tecnología & Futuro, 2009
Determination of Membrane Efficiency (ME) is a very useful tool in the study of the chemical component of wellbore stability since it is a variable input in chemical elastic models (Lomba, Chenevert & Sharma, 2000).

calibrar: An R package for fitting complex ecological models

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 3, Page 507-519, March 2025.
Abstract The fitting or parameter estimation of complex ecological models is a challenging optimisation task, with a notable lack of tools for fitting complex, long runtime or stochastic models. calibrar is an R package that is dedicated to the fitting of complex models to data.

L'imparfait et la modalité déontique

open access: yesLinguistica, 2002
L'imparfait, cette valeur controversée en français (comme d'ailleurs pour une grande partie aussi dans les autres langues romanes, grâce à une riche tradition latine) oscille essentiellement entre ses emplois aspectuo-temporels d'une part et ses ...

The Benefits of Hierarchical Ecosystem Models: Demonstration Using EcoState, a New State‐Space Mass‐Balance Model

open access: yesFish and Fisheries, Volume 26, Issue 2, Page 203-218, March 2025.
ABSTRACT Ecosystem models predict changes in productivity and status for multiple species, and are important for incorporating climate‐linked dynamics in ecosystem‐based fisheries management. However, fishery regulations are primarily informed by single‐species stock assessment models, which estimate unexplained variation in dynamics (e.g., recruitment,

Nouvelle méthode de marquage vital d'oeufs de salmonidés par incorporation osmotique de tétracycline à la fécondation : expériences préliminaires sur des oeufs de truite fario (Salmo trutta fario)et de truites arc-en-ciel (Oncorhynchus mykiss)

open access: yesKnowledge and Management of Aquatic Ecosystems, 1989
Une méthode a été développée pour marquer les oeufs de truites par de la tétracycline au moment de leur fécondation. La tétracycline mélangée à l'eau qui s'infiltre par osmose dans les oeufs au moment de la fécondation ("swelling water") y persiste jusqu'

An Integrated Global‐To‐Regional Scale Workflow for Simulating Climate Change Impacts on Marine Ecosystems

open access: yesEarth's Future, Volume 13, Issue 2, February 2025.
Abstract As the urgency to evaluate the impacts of climate change on marine ecosystems increases, there is a need to develop robust projections and improve the uptake of ecosystem model outputs in policy and planning. Standardizing input and output data is a crucial step in evaluating and communicating results, but can be challenging when using models ...

Disintegration highway: Towards a psychogeography of planetary urban breakdown

open access: yesSingapore Journal of Tropical Geography, Volume 46, Issue 1, Page 138-156, January 2025.
This paper develops a psychogeographical approach to our apocalyptic urban present, based on a journey down a highway on the outskirts of the city of Iquitos in the Peruvian Amazon. The intensity of psychogeographical method brings out elements of the senselessness and violence of planetary urbanization imperceptible at more abstract levels of analysis,
