MEDUSA: Marine benthic Ecological Data from Underwater imagery Surveys of sub-Antarctic Crozet environments

Collected date : from 4 Nov 2021 to 24 Nov 2022
Creators : Yann Lelièvre

Inscribed on the UNESCO World Heritage list, the sub-Antarctic Crozet archipelago is located in a region facing significant environmental changes impacting a poorly known marine biodiversity. Underwater imagery constitutes a valuable non-invasive approach for gathering ecological data and improving ...

PROTEKER: a near-shore submarine observatory in the Kerguelen Islands for the long-term monitoring of benthic habitats

Collected date : from Nov 2011 ongoing
Creators : Thomas Saucède

PROTEKER is a pilot program that aims at establishing a baseline for assessing the impact of climate change on near-shore marine ecosystems of the Kerguelen Islands by implementing an ecological and genetic monitoring at reference sites. The high diversity of coastal marine ecosystems is usually ...

Physicochemical and bacteriological characteristics of water - Arcier watershed - 2020-2022

Physical characteristics, major ions, minor ions, trace elements measured from May 2020 to February 2022 in five sites of the Arcier karst watershed (Doubs, France), as well as at the Arcier spring. These measurements were complemented by the acquisition of extended spectrum beta-lactamase ...

Synthesis, antidiabetic activity and molecular docking study of rhodanine-substitued spirooxindole pyrrolidine derivatives as novel α-amylase inhibitors

In a sustained search for novel α-amylase inhibitors for the treatment of type 2 diabetes mellitus (T2DM), we report herein the synthesis of a series of nineteen novel rhodanine-fused spiro[pyrrolidine-2,3′-oxindoles]. They were obtained by one-pot three component [3 + 2] cycloaddition of stabilized ...

Nitrogen Hydrate Cage Occupancy and Bulk Modulus Inferred from Density Functional Theory-Derived Cell Parameters

Gas clathrate hydrate solid materials, ubiquitous in nature as found either on the ocean floor, permafrost on the Earth, or in extraterrestrial planets and comets, are also technologically relevant, for example, in energy storage or carbon dioxide sequestration. Nitrogen hydrate, in particular, is ...

Modelling the response of Antarctic marine species to environmental changes. Methods, applications and limitations

Collected date : from 1 Jan 2017 to 9 Jul 2021

Ecological modelling is nowadays widely used to highlight the environmental conditions that influence the species ecological niche and better understand their response to environmental changes. Methodological challenges are however present for Southern Ocean marine case studies and it is important ...

Diversity-oriented Synthesis of Spiropyrrolo[1, 2-a]isoquinoline Derivatives via Diastereoselective and Regiodivergent Three-component 1,3-Dipolar Cycloaddition Reactions: In vitro and in vivo Evaluation of the Antidiabetic Activity of Rhodanine Analogues

Collected date : from 2018 to 2021

An efficient diastereoselective route is developed to get access to novel spiropyrrolo[1,2-a]isoquinoline-oxindole skeletons by a one-potthree-component [3 + 2] cycloaddition reaction of (Z)-5-arylidene-1,3-thiazolidine-2,4-diones, isatin derivatives, and 1,2,3,4-tetrahydroisoquinoline (THIQ). ...

Sampling of Mediterranean fan mussel specimens (Pinna nobilis) for molecular analyses of the byssus and of the shell matrix

Collected date : from 8 May 2017 to 16 May 2017
Creators : Frédéric Marin

This document describes a field mission carried out in May 2017, at the Observatoire Océanologique de Villefranche-sur-Mer. This mission aimed at collecting live specimens as well as dead shells from the Mediterranean fan mussel, Pinna nobilis, an endemic species protected by European Directive ...

Reactivity of CuI and CuBr toward Dialkyl Sulfides RSR: From Discrete Molecular Cu4I4S4 and Cu8I8S6 Clusters to Luminescent Copper(I) Coordination Polymers

Collected date : from 2010 to 2014

The CuX salts (X = I, Br) react with SR2 to form molecular clusters of the types [(R2S)4(Cu4I4)] and [(R2S)6(Cu8I8)] or to give 1D polymers and 2D metal−organic frameworks. The cluster nuclearity and connectivity as well as the dimensionality of these compounds depend on the steric demand of SR2, ...
