Available in PDF, EPUB and Kindle. Book excerpt: L'OBJECTIF ETAIT D'ANALYSER L'EFFET DE COURTES PERIODES DE HAUTES TEMPERATURES SUR LA CROISSANCE ET LE DEVELOPPEMENT DU POIS PENDANT LES DIFFERENTES PHASES DE L'ELABORATION DU NOMBRE DE GRAINES. DES CONTRAINTES THERMIQUES (CT) DE QUELQUES JOURS ONT ETE APPLIQUEES SUR DES PLANTES CULTIVEES EN SERRE, PAR TRANSFERT EN CHAMBRE DE CULTURE, ET SUR DES PLANTES AU CHAMP, PAR APPLICATION D'UN ABRI A EFFET DE SERRE. LES CT ONT ETE CARACTERISEES PAR LA TEMPERATURE DES EXTREMITES APICALES DES PLANTES (TEA) : CT MODEREES (TEA MAX 30C) ET CT SEVERES (TEA MAX 35C). CES CT NE SONT PAS RARES DANS LES ZONES DE CULTURE DU POIS EN FRANCE. UN DEFICIT HYDRIQUE PEUT INDUIRE DES CT MODEREES. UNE COURTE PERIODE DE TEMPERATURE ELEVEE REDUIT, DE MANIERE REVERSIBLE, LA PHOTOSYNTHESE NETTE ET L'EFFICIENCE BIOLOGIQUE DE CONVERSION DU RAYONNEMENT ABSORBE EN MATIERE SECHE. ELLE REDUIT LA SURFACE FOLIAIRE DE TOUS LES PHYTOMERES IMMATURES ET PEUT DONC DIMINUER L'EFFICIENCE D'ABSORPTION DU RAYONNEMENT PAR LE BIAIS D'UNE REDUCTION DE L'INDICE FOLIAIRE. L'EFFET DES CT PEUT ETRE INTEGRE DANS UN MODELE DE PRODUCTION DE BIOMASSE, S'IL INCLUT UN MODULE DE CROISSANCE FOLIAIRE PAR PHYTOMERE. UNE CT MODEREE INDUIT UN ARRET ANTICIPE DE LA PRODUCTION DE NOUVEAUX PHYTOMERES PAR LE MERISTEME CAULINAIRE ET REDUIT LE NOMBRE DE FLEURS. LES AVORTEMENTS DE FLEURS ET BOUTONS SONT LOCALISES SUR LE HAUT DE LA TIGE ET NE SONT PAS LIES A L'AGE DE L'ORGANE AU MOMENT DE LA CONTRAINTE MAIS PROBABLEMENT A SON AGE AU MOMENT DE L'ARRET DE FONCTIONNEMENT DU MERISTEME APICAL. UNE CT MODEREE ET TARDIVE N'AFFECTE PAS LE NOMBRE DE GRAINES PAR PLANTE MAIS MODIFIE LEUR REPARTITION SUR LA TIGE EN FAVEUR DES PREMIERS PHYTOMERES REPRODUCTEURS. UNE CT PLUS PRECOCE REDUIT LE NOMBRE DE GRAINES ESSENTIELLEMENT PAR LA REDUCTION DU NOMBRE FINAL DE PHYTOMERES REPRODUCTEURS EMIS PAR LA PLANTE. UNE CT SEVERE PROVOQUE DES AVORTEMENTS DE BOUTONS FLORAUX INDEPENDAMMENT DE L'ARRET DU MERISTEME APICAL ET REDUIT LE NOMBRE DE GRAINES PAR PLANTE.

This book was released on 2020-01-20 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an insight into how a country contributes to the GHG emissions reductions required to keep global warming within the limits set by the Paris Agreement arrived at COP21 in 2015. It shows what actions are needed for the implementation plan that Fiji will use to satisfy its quota (i.e. its Nationally Determined Contribution or NDC) of the total GHG emissions reductions. It is a primary resource material for those who wish to obtain an understanding of the science behind climate change mitigation. It reveals the behind-the-scenes action that takes place to convert the rhetoric of climate change into the action on the ground that actually reduces the GHG emissions and global warming. The book also presents a critique of methods adopted by nations in meeting their NDCs to emissions reductions as agreed at the Paris Agreement, and suggests improvements.

This book was released on 2020-10-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second volume on dormancy in aquatic organisms. The book is divided into three parts whereby the first part is devoted to several groups of aquatic organisms which are under-studied in terms of the dormancy’s role in the life cycle. The second part looks at the use of dormancy phenomena in science and potential human applications. Furthermore, part 3 comprises of examples of using modeling in relation to dormancy phenomenon and it opens with a theoretical analysis of studies of biological information, including seasonal information. This work can be used as a text book for students as well as a manual for science and practice purposes in ecology, aquaculture, nature protection and space researches with regards to creating ecological life supporting systems and discovering extraterrestrial life on other planets with harsh environmental conditions.
