A review of the ecological knowledge on the species Batrachoides liberiensis in estuarine and lagoon environments of West Africa

African Journal of Ecology, Volume 61, Issue 2, Page 298-305, June 2023., 2023
Abstract Scientific fishing programmes were carried out between 1979 and 2013 in several West African estuarine, coastal and lagoon ecosystems. Batrachoides liberiensis represented only 5.2% of the occurrences, of which the majority were recorded in the Sine Saloum estuary.

Relationships between saturated paste and 1:1 or 1:5 soil/water extract sodium adsorption ratios

Irrigation and Drainage, Volume 72, Issue 2, Page 503-514, April 2023., 2023
Abstract This study investigates the relationship between the sodium adsorption ratio acquired by the saturated paste extract (SARe) method and those acquired by 1:1 and 1:5 soil/water extracts (SAR1:1 and SAR1:5) by using 122 surface soil samples from 5 agricultural areas of Greece.

"La maree de Salinite Dans le Capibaribe" Recife-Bresil

Tropical Oceanography, 1959
Esse estudo mostra a penetração da salinidade na embocadura do Capibaribe, a estratificação das águas e o deslocamento das curvas isohalinas. Por outro lado, o estudo químico mostra um constante paralelismo entre as variações de pH e do oxigênio dissolvido. As mesmas não estão, todavia, ligadas às variações de salinidade, mas à influência da insolação,

ACTUAL WATER USE OF YOUNG DATE PALM TREES AS AFFECTED BY AMINOLEVULINIC ACID APPLICATION AND DIFFERENT IRRIGATION WATER SALINITIES

Irrigation and Drainage, Volume 69, Issue 3, Page 427-440, July 2020., 2020
Abstract The Arabian Gulf countries are facing unprecedented water management challenges owing to limited water resources and salinization of the soil. Date palm trees represent a crucial socio‐economic asset in the region. Improving water productivity and tolerance to salinity are the most viable options.

Changes in West African Summer Monsoon Precipitation Under Stratospheric Aerosol Geoengineering

Earth's Future, Volume 8, Issue 7, July 2020., 2020
Abstract Stratospheric aerosol geoengineering (SAG) is suggested as a potential way to reduce the climate impacts of global warming. Using simulations from the Geoengineering Large Ensemble project that employed stratospheric sulfate aerosols injection to keep global mean surface temperature and also the interhemispheric and equator‐to‐pole temperature

Multiple trait dimensions mediate stress gradient effects on plant biomass allocation, with implications for coastal ecosystem services

Journal of Ecology, Volume 108, Issue 4, Page 1227-1240, July 2020., 2020
Our focal saltmarsh grass expressed conservative leaf traits and invested more in below‐ground biomass under high salinity. Yet, it was still able to express a high proportion of coarse roots and produce greater above‐ground biomass under high redox.

Effet de l’interaction lumiere-salinite sur l’activite du photosysteme ii des feuilles excisees de maïs [PDF]

African Crop Science Journal, 2015
La diminution de la croissance vegetative observée chez nombreuses plantes, soumises au stress salin et exposées à des conditions naturelles d’ensoleillement, est souvent associée à une baisse de leur activité photosynthétique. Cependant les mécanismes de l’inhibition photosynthétique sont encore peu étudiés. Le photosystème II (PS II) est considéré un

Paleobiology of the Latest Tithonian (Late Jurassic) Ammonite Salinites grossicostatum Inferred from Internal and External Shell Parameters

PLOS ONE, 2016
Based on material from the uppermost Tithonian La Caja Formation at Puerto Piñones, northeastern Mexico, the complete ontogenetic development (protoconch to adult) of the ammonite Salinites grossicostatum is outlined by a detailed morphometrical shell analysis.

Evaluation de tolérance de nouveaux porte-greffes hybrides d’agrumes vis-à-vis de la salinité

African and Mediterranean Agricultural Journal - Al Awamia
Au Maroc, les agrumes sont largement cultivés dans les zones arides et semi-arides où le problème de la salinité se pose et affecte la productivité. Pour faire face à cette contrainte biotique l’utilisation du porte-greffe reste le moyen le plus pratique.

Quelles exigences de qualités pour les poissons d'élevage et issus de la pêche ?

INRAE Productions Animales, 2015
Le produit alimentaire « poisson » présente la particularité de recouvrir de nombreuses espèces animales, provenant de milieux aquatiques variés (en termes de qualité d'eau, température, salinité…) et issus de captures dans le milieu « naturel » ou de ...
