Ecological drivers of the Ediacaran-Cambrian diversification of Metazoa
Douglas H. Erwin, Sarah Tweedt
Organismal modifications to their physical and chemical environment play a significant role in structuring many modern ecosystems, and experimental evidence suggests that such behavior can increase diversity. Despite the important role such activities play in connecting ecology and evolution, less is known of the macroevolutionary impact of such influences, especially their role during major evolutionary transitions. The Ediacaran-Cambrian diversification ...

Garantie de non réussite dans la sécurité de l'eau: Ne lisez pas ce qui suit et aucune garantie de succès.
C'est ce qui explique pourquoi la qualité de l'eau descend très rapidement en dépit de tous les efforts pour le protéger.
http://5bio5.blogspot.com/2013/01/why-water-quality-goes-down-so-rapidly.html
Une série de ces publications innovantes (voir ci-dessous) a découvert de nouveaux dangers sous-estimés de la qualité de l'eau.
Ces dangers étaient invisibles ou inaperçues ou ignorées.
C'est l'une des causes de la raison pour laquelle tous les efforts énormes pour lutter contre la pollution chimique, l'eutrophisation et la prolifération d'algues n'ont presque pas de fruits.

Mots clés: publications, des mesures nouvelles, des innovations, de découvertes, de nouveaux concepts, de la sécurité de l'eau, le développement durable, sciences de l'environnement, de l'écologie.
Ignorant les nouveaux risques environnementaux découverts dans ces publications garantit que tous les efforts actuels de lutte contre la pollution chimique de l'eau douce, les écosystèmes marins, estuariens, afin d'atténuer l'eutrophisation, et d'empêcher la prolifération d'algues échouera.

Sur les nouveaux résultats de l'étude des interactions chimiques et biotiques et chimie de l'environnement - Publications SA évaluation Ostroumov.
Cette brève analyse de certains résultats et vainqueur publications bourse Fulbright, membre de l'Académie russe des sciences naturelles Dr. Sergey Ostroumov Andreevych (Université Lomonosov de Moscou, baptisé) Intérêts de recherche: sciences de l'environnement et de l'écologie.
Un certain nombre d'articles ont été publiés qui mettait l'accent sur les interactions chimiques et biotiques dans la biosphère [1-46]. Nous tenons à répondre à ces publications et d'exprimer leur opinion. Dans ces publications, de nouveaux faits ont été révélés de nouveaux concepts fondamentaux ont été formulées. Ils contribuent un regard neuf sur ces deux aspects de ces questions, à savoir:
(1) comment les produits chimiques affectent les organismes ([2, 9], et d'autres.) Et
(2) faire organismes produisent des effets sur la composition chimique de l'environnement ([1, 2, 4, 6], etc.)
Ce travail a conduit à l'émergence de nouveaux concepts fondamentaux en écologie et en sciences de l'environnement et de la biosphère [2, 3, 5, 10], pour créer une écologie nouvelle science biochimique [28, 29]. En outre, les faits nouveaux et les concepts révélés utiles pour la fabrication de base scientifique pour les nouvelles technologies de surveillance et de nettoyage de l'environnement [1, 2, 4, 7, 8] pour la biodiversité [24 - 27, 32] développement durable [33 à 46 ].
Les travaux du Dr S. Ostroumov et ses collaborateurs sur les interactions chimiques et biotiques sur l'écologie, la biologie, l'étude de la biosphère a une approche fondamentale, la nouveauté, et contiennent un grand nombre de nouveaux résultats de leurs expériences. Ces résultats sont d'une grande importance pratique pour la sécurité de l'environnement, l'utilisation durable des ressources naturelles, le développement durable, la biodiversité, le développement de la science des nanomatériaux, l'amélioration et la modernisation de l'enseignement supérieur. Ses réalisations ont été reconnues tant dans son pays qu'à l'étranger.

RÉSUMÉ.
Avis positif de cette série de publications (articles et livres), auteur et co-auteur d'une bourse Fulbright SA Ostroumov (MSU). Il est conclu que le nombre d'œuvres d'SA Ostroumov et ses collaborateurs sur les produits chimiques et biotiques interactions sur l'écologie, la biologie et l'étude de la biosphère a une approche fondamentale, la nouveauté, et représente un grand nombre de nouveaux résultats de ses expériences. Ces résultats sont d'une grande importance pratique pour la sécurité de l'environnement, l'utilisation durable des ressources naturelles, le développement durable, la biodiversité, le développement de la science des nanomatériaux, l'amélioration et la modernisation de l'enseignement supérieur.

Garantie de non réussite dans la sécurité de l'eau: Ne lisez pas ce qui suit et aucune garantie de succès.
C'est ce qui explique pourquoi la qualité de l'eau descend très rapidement en dépit de tous les efforts pour le protéger.
http://5bio5.blogspot.com/2013/01/why-water-quality-goes-down-so-rapidly.html
Une série de ces publications innovantes (voir ci-dessous) a découvert de nouveaux dangers sous-estimés de la qualité de l'eau.
Ces dangers étaient invisibles ou inaperçues ou ignorées.
C'est l'une des causes de la raison pour laquelle tous les efforts énormes pour lutter contre la pollution chimique, l'eutrophisation et la prolifération d'algues n'ont presque pas de fruits.
**
Mots clés: publications, des mesures nouvelles, des innovations, de découvertes, de nouveaux concepts, de la sécurité de l'eau, le développement durable, sciences de l'environnement, de l'écologie.
Ignorant les nouveaux risques environnementaux découverts dans ces publications garantit que tous les efforts actuels de lutte contre la pollution chimique de l'eau douce, les écosystèmes marins, estuariens, afin d'atténuer l'eutrophisation, et d'empêcher la prolifération d'algues échouera.
