Ecology Letters, 2015
The marine-freshwater boundary is a major biodiversity gradient and few groups have colonised both systems successfully. Fishes have transitioned between habitats repeatedly, diversifying in rivers, lakes and oceans over evolutionary time. However, their

Comparative ISS accelerometric analyses
Acta Astronautica, 2014Abstract Two accelerometric records coming from the SAMSes es08 sensor in the Columbus module, the so-called Runs 14 and 33 in terms of the IVIDIL experiment, has been studied here using standard digital signal analysis techniques. The principal difference between both records is the vibrational state of the IVIDIL experiment, that is to say, during ...

Comparative Analyses of Bacteriophage Genomes
Bacterial viruses (bacteriophages or phages) are the most abundant and diverse biological entities on Earth. There is a renewed worldwide interest in phage-centered research motivated by their enormous potential as antimicrobials to cope with multidrug-resistant pathogens. An ever-growing number of complete phage genomes are becoming available, derivedFernando Pacheco Nobre, Rossi +5 more

Multimodel-Inference in Comparative Analyses
2014Multimodel inference refers to the task of making a generalization from several statistical models that correspond to different biological hypotheses and that vary in the degree of how well they fit the data at hand. Several approaches have been developed for such purpose, and these are widely used, mostly for intraspecific data, i.e., in a non ...

Comparative Analyses of Rigid Pavements
Journal of Transportation Engineering, 1983Stress conditions in concrete pavements were analyzed using the finite element method for slabs on liquid and elastic subgrades. The study consisted of the following parts: (1) The effect of the efficiency of load transfer across the joints; (2) the loading positions that produce the most critical stress and deflection conditions in the pavement; (3 ...

Comparative EST Analyses in Plant Systems
2005Expressed sequence tag (EST) data are a major contributor to the known plant sequence space. Organization of the data into non-redundant clusters representing tentative unique genes provides snapshots of the gene repertoires of a species. This chapter reviews availability of sequences and sequence analysis results and describes several resources and ...

Analyse comparative et informatique
Canadian Journal of Political Science, 1968The Comparative Analysis of DataFor several years political scientists have been studying the possibilities of using computers to advance the study of comparative politics. Some have urged that the development of a truly empirical political theory would benefit from the use of computers on a massive scale.

Historic preservation: A comparative analyses
Sociological Forum, 1989Historic preservation has, to date, received relatively little attention from sociologists, usually meriting only brief mention under topics of urban gentrification or community organization. But within the context of its history and its significance in modern society, preservation emerges as a multilevel response to industrialization and related ...

Systematic Biology, 2014
Both gene-tree discordance and unrecognized diversity are sources of error for accurate estimation of species trees, and can affect downstream diversification analyses by obscuring the correct number of nodes, their density, and the lengths of the ...

Polytomies in Comparative Analyses of Continuous Characters
Systematic Biology, 1993ple species. One requirement of the meth? od is that the true phylogeny linking the species in the data set be known in full, including the lengths of the branches in units of expected variance of change for the character(s) being studied (see Harvey and Pagel, 1991; Martins and Garland, 1991; Garland et al., 1992). In practice, we cannot be certain of
