This article analyses the relationship between trait emotional intelligence and academic performance, controlling for the effects of IQ, personality, and self-concept dimensions. A sample of 290 preadolescents (11-12 years old) took part in the study. The instruments used were (a) Trait Emotional Intelligence Questionnaire—Adolescents Short Form (TEIQue-ASF); (b) Children’s Personality Questionnaire (CPQ; Form A, Part A); (c) IQ test TIDI-2; (d) Adaptation Questionnaire (CAI-1); and (e) academic performance. A positive and significant correlation coefficient between trait EI measured by the TEIQue-ASF and general academic performance was found. The TEIQue-ASF showed incremental validity to predict general academic performance, after controlling for intelligence, personality, and self-concept characteristics.

The Emotional Quotient Questionnaire for Youth Version (EQ-i:YV) was tested and validated using a sample of 1655 Spanish students. A detailed psychometric analysis provided evidence in support of the reliability of the EQ-i:YV and the robustness of its proposed five-factor structure. Using different subsamples of participants, the associations between the EQ-i:YV and a series of relevant constructs (general intelligence, personality traits, self-concept, and academic performance) were examined, which also included data on another trait EI measure (TEIQue-ASF). Overall, the EQ-i:YV showed expected relationships to all other constructs. Finally, the standard score provided can help to interpret the emotional skills, competences and facilitators of Spanish children and adolescents.Keywords: Emotional intelligence, EQ-i:YV, standard scores, psychometric properties, validity and reliability. ResumenEl objetivo es validar el cuestionario de inteligencia emocional (EQ-i:YV, Emotional Quotient inventory: Young Version). En el estudio han participado 1655 estudiantes. Los análisis psicométricos aportan evidencias sobre la fiabilidad y validez de la estructura de cinco factores del cuestionario. Se han utilizado diferentes submuestras para estudiar la relación entre el EQ-i: YV y una serie de constructos relevantes (inteligencia general, rasgos de personalidad, autoconcepto y rendimiento académico); además se ha incluido otra medida de la inteligencia emocional (TEIQue-ASF, Trait Emocional Intelligence Questionaire-Adolescent Short Form). Los datos muestran que el EQ-i:YV mantiene las relaciones esperadas con el resto de constructos estudiados. Finalmente, se presentan los baremos del EQi:YV , que ayudan a interpretar las puntuaciones en niños y adolescentes españoles.Palabras clave: Inteligencia emocional, EQ-i:YV baremos, propiedades psicométricas (validez y fiabilidad).

The mesozooplankton community was analysed in a large region of the Argentine Shelf (34°–41°S) on the main spring spawning ground of the anchovy (Engraulis anchoita), and its spatial pattern was related to the hydrographic conditions. Copepods smaller than 1 mm dominated the community. Three faunistic areas were identified by cluster analysis: northern coastal area (NCA), southern coastal area (SCA), and shelf area (SA), each with distinct physical conditions. The NCA, influenced by the Río de la Plata estuary, had relatively high temperature, the lowest salinity, and the highest stratification values. The SCA had the highest salinity and a vertically homogeneous water column. The SA, vertically stratified, was influenced by the Río de la Plata estuary and by Subantarctic shelf waters and had the lowest temperature values and the greatest depths. Canonical correlation analysis was used to analyse the relationship between zooplankton and physical variables and four zooplankton assemblages were identified. Group A included the copepods Calanus australis, C. simillimus, Clausocalanus brevipes, Centropages brachiatus, Drepanopus forcipatus, Oithona atlantica, and O. helgolandica, and was preferentially distributed in the SA. Group B, composed of the copepods Acartia tonsa and Corycaeus spp. and the cladoceran Pleopis polyphemoides, showed a strong preference for the NCA. Group C included Labidocera fluviatilis, Ctenocalanus vanus, Paracalanus spp., Calanoides cf. carinatus, Euterpina acutifrons, Oithona nana, and the cladoceran Evadne nordmanni, and was preferentially distributed in coastal areas (NCA and SCA). Group D only included the cladoceran Podon intermedius and was mainly located in high salinity waters of the SCA. Small, omnivorous, fast-reproducing species (groups B, D, and most of C) are better adapted to warmer variable and less productive coastal areas, whereas larger herbivorous species (most of group A) seem to better exploit colder stratified and more productive shelf waters. The mesozooplankton community provides adequate food for E. anchoita larvae in coastal areas and for adults in shelf waters.

The massive spawning of anchovy (Engraulis anchoita) in Argentine waters takes place in spring in the coastal sector off the Buenos Aires Province, with the highest concentrations of spawners occurring in front of the Río de la Plata mouth. In October 1995, the size structure, composition and abundance of the zooplankton community was analyzed and related to the hydrography and the abundance of anchovy eggs. Oceanographic conditions were different from the recorded means for the season. A higher proportion of the colder and more saline shelf waters were present in the coastal area and strong haloclines were not observed. High values of plankton biomass were observed in the estuarine frontal area and in the weakly stratified waters of the median shelf. The cluster analysis of the stations gave rise to the formation of coastal (CA), transitional (TA) and shelf (SA) faunistic areas. Mesozooplankton smaller than 1 mm total length (TL) dominated the whole area. The copepods, Paracalanus spp. and Oithona similis, and the cladocerans, Evadne nordmanni and Podon spp., constituted the bulk of this mesozooplankton fraction. Oithona similis was the dominant species in the SA. The copepod, Acartia tonsa (1–2 mm TL), was extremely abundant in the estuarine front (more than 17 600 individuals m–3) followed by appendicularians, members of Pseudocalanidae, anchovy eggs and decapod larvae. Species of Calanidae (Calanoides carinatus and Calanus simillimus), the amphipod hyperiid, Themisto gaudichaudii, and the euphausiid, Euphausia lucens, largely dominated the macrozooplankton (>2 mm TL) in the TA and SA. In the CA, significant positive correlations between the abundance of small copepods (size ranges <1 and 1–2 mm) and anchovy eggs were found. Trophic implications of these findings for first-feeding anchovy larvae were discussed. The adequacy of the TA and SA as feeding ground for adults of anchovy was evaluated.
