Among-year variation in the repeatability, within- and between-individual, and phenotypic correlations of behaviors in a natural population.

When mean behaviors correlate among individuals, they form behavioral syndromes. One way to understand the evolution of such a group-level phenomenon is to compare horizontally patterns of correlations among populations (or species) or follow longitudinally the same population over years in the light of parallel differences in the environment. We applied the longitudinal approach to 8-year field data and analyzed phenotypic correlations, and their within- and between-individual components, among three behaviors (novelty avoidance, aggression, and risk-taking) in male collared flycatchers, , in a meta-analytic framework.

A new HLA-B allele, B*49:34, sequenced in a Spanish individual.

HLA-B*49:34 shows one nucleotide difference regarding B*49:01:01 at codon 66 (ATC>GTC, I66>V66).

Sorption, desorption and leaching potential of sulfonylurea herbicides in Argentinean soils.

The sulfonylurea (SUs) herbicides are used to control broadleaf weeds and some grasses in a variety of crops. They have become popular because of their low application rates, low mammalian toxicity and an outstanding herbicidal activity. Sorption is a major process influencing the fate of pesticides in soil.

Characterization of a novel HLA-DRB1 allele: DRB1*11:153.

HLA-DRB1*11:153 differs from DRB1*11:131 by one nucleotide at position 286 where C > A, (codon 67 CTC>ATC), resulting in an amino acid substitution, 67L>67I.
