Practical methods for non-destructive measurement of tree leaf area Inra
Leroy, C.; Saint-André, L.; Auclair, D..
In an agroforestry context, the knowledge of leaf area is an important parameter to take into consideration because tree foliage shades the intercrop. Single leaf measurement (for example leaf length and width) is a widely used method to estimate leaf area in a rapid non-destructive way. In this study, the objectives were to estimate the leaf area of different leaf sizes and shapes for Acacia mangium Willd. (Mimosaceae), Tectona grandis L. (Verbenaceae), Hevea brasiliensis Muell.-Arg. (Euphorbiaceae), and Swietenia macrophylla King. (Meliaceae) Indonesian agroforestry trees. In order to characterise leaf area in field conditions a digital photograph method was used. Leaf length was measured in order to build relationships between leaf length versus actual...

Social and semantic coevolution in knowledge networks Inra
Roth, C.; Cointet, J.P..
Socio-semantic networks involve agents creating and processing information: communities of scientists, software developers, wild Contributors and webloggers are, among others, examples Of Such knowledge networks. We aim at demonstrating that the dynamics of these communi ties can be adequately described as the coevolution of a social and a socio-semantic network. More precisely, we will first introduce a theoretical framework based on a social network and a socio-semantic network, i.e. an epistemic network featuring agents. concepts and links between agents and between agents and concepts. Adopting a relevant empirical protocol. we will then describe the joint dynamics of social and socio-semantic structures, at both macroscopic and microscopic scales,...

The FeFe hydrogenase of Nyctotherus ovalis has a chimeric origin Inra
Boxma, B.; Ricard, G.; van Hoek, A. H.; Severing, E.; Moon-van der Staay, S.Y.; van der Staay, G.W.M.; van Alen, T.A.; de Graaf, R.M.; Cremers, G.; Kwantes, M.; McEwan, N.R.; Newbold, C.J.; Jouany, J.P.; Michalowski, T.; Pristas, P.; Huynen, M.A.; Hackstein, J.H.P..
Background: The hydrogenosomes of the anaerobic ciliate Nyctotherus ovalis show how mitochondria can evolve into hydrogenosomes because they possess a mitochondrial genome and parts of an electron-transport chain on the one hand, and a hydrogenase on the other hand. The hydrogenase permits direct reoxidation of NADH because it consists of a [ FeFe] hydrogenase module that is fused to two modules, which are homologous to the 24 kDa and the 51 kDa subunits of a mitochondrial complex I.Results: The [ FeFe] hydrogenase belongs to a clade of hydrogenases that are different from well-known eukaryotic hydrogenases. The 24 kDa and the 51 kDa modules are most closely related to homologous modules that function in bacterial [ NiFe] hydrogenases. Paralogous,...
