Définition d’un indice composition pour le phytoplancton en Manche- Atlantique, à partir des données du micro-phytoplancton du REPHY et des réseaux régionaux, et des mesures complémentaires de la flore phytoplanctonique acquises avec des techniques novatrices. Action 3 – Livrable 1. Propositions pour un indice de composition du phytoplancton, basé sur les résultats des méthodes microscopie, pigments et diversité génétique. Rapport final, février 2016

Autores: Hernandez Farinas, Tania; Brun, Melanie; Siano, Raffaele; Delmas, Daniel.
This deliverable is composed of two reports which propose indice of phytoplankton composition, based respectively on the results of pigment and genetic diversity methods, and the results of microscopy method. Proposals based on the results of pigment and genetic diversity methods. The present work is a continuation of several studies carried out in the past (Siano and Delmas, 2013, 2015) on investigating an indicator of phytoplankton diversity using two methods complementary to optical microscopy: the genetic diversity analyzed with metabarcoding (exhaustive analysis of the diversity and relative abundance of OTUs, i.e. groups of sequences identified by their genetic resemblance) and the pigmentary diversity (analysis of the diversity and abundance of...

Use of the correlation coefficient in agricultural sciences: problems, pitfalls and how to deal with them
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Kozak,Marcin; Krzanowski,Wojtek; Tartanus,MaŁgorzata.
This paper discusses a number of aspects concerning the analysis, interpretation and reporting of correlations in agricultural sciences. Various problems that one might encounter with these aspects are identified, and suggestions of how to overcome these problems are proposed. Some of the examples presented show how mistaken and even misleading the interpretation of correlation can be when one ignores simple rules of analysis.

Abstract: The population of humpback whales from breeding stock A is increasing, and little is known about the routes used by humpbacks that move north of the main calving area of Brazil, the Abrolhos Bank. The aim of this study was to describe the movements of humpback whales in a reoccupation wintering area (Serra Grande, Bahia state, Brazil) based on land-based surveys to test if movement patterns change during the season and between years, due to group composition, behavioral state, and distance to the coast. The mean leg speed of the groups sighted was 6.88 (±2.92) km/h, and leg speed was positively correlated with distance to the coast. There was an increase in leg speed and distance to the coast with increasing number of escorts in the groups with...
