Última Karyotypic studies and morphological analysis of some reproductive features in five species of Conyza (Astereae: Asteraceae) from Northeastern Argentina Boletín de la Sociedad Urdampilleta,Juan D.; Amat,Aníbal G.; Bidau,Claudio J.. The cosmopolitan genus Conyza Less. comprises about 100 species, 22 of which occur in Argentina. Current taxonomic treatments, largely based on exomorphological characters, are insufficient to characterize and circumscribe some of their polymorphic species. Interspecific variations in inflorescences typology and capitula structure, as well as karyotypic aspects, were studied in five species of Conyza that naturally occur in Misiones Province (Argentina): C. blakei (Cabrera) Cabrera, C. bonariensis (L.) Cronquist var. bonariensis, C. glandulitecta Cabrera, C. primulaefolia (Lam.) Cuatrec. & Lourteig, C. sumatrensis (Retz.) E. Walker var. sumatrensis and C. sumatrensis (Retz.) E. Walker var. floribunda (Kunth) J. B. Marshall. Chromosome numbers for...

The rio das Velhas, located in central Minas Gerais State (Brazil), is a major tributary of the rio São Francisco. Despite several anthropogenic pressures, this basin supports more than 115 fish species. The aim of this study was to compare the morphological space occupied by fish assemblages in four regions (headwaters, upper, middle, and lower course) along the channel of the rio das Velhas. We try to answer the following question: Is there a change in the morphological organization of the fish along the longitudinal gradient of the river? Individuals from 67 species, collected at several sites in the basin from 1999 to 2008, were measured for 11 morphological attributes related to swimming behavior and habitat use. Through the graphs, the first two... Tipo: Info:eu-repo/semantics/article Palavras-chave: Community ecology; Ichthyofauna; Interspecific variation; Morphometry; Rio São Francisco. Ano: 2012 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252012000200017 TRY – a global database of plant traits Naturalis Kattge, J.; Lens, F.. Plant traits – the morphological, anatomical, physiological, biochemical and phenological characteristics of plants and their organs – determine how primary producers respond to environmental factors, affect other trophic levels, influence ecosystem processes and services and provide a link from species richness to ecosystem functional diversity. Trait data thus represent the raw material for a wide range of research from evolutionary biology, community and functional ecology to biogeography. Here we present the global database initiative named TRY, which has united a wide range of the plant trait research community worldwide and gained an unprecedented buy-in of trait data: so far 93 trait databases have been contributed. The data repository currently...

Ano: 2011 URL: http://www.repository.naturalis.nl/record/423730 Variation in root morphology of epiphytic orchids along small-scale and large-scale moisture gradients Acta Botanica Einzmann,Helena J. R.; Schickenberg,Nina; Zotz,Gerhard. ABSTRACT Root morphology is expected to respond to environmental conditions. Two earlier studies reported predictable changes in the structure of the velamen radicum (common in monocotyledons) along rainfall gradients, which was expected from its assumed role in plant-water-relations. The present study expanded on this idea by analysing nine root traits that can be linked to root function, including velamen structure, along two moisture gradients of different spatial scales: 1) along the vertical gradient of a lowland forest in central Panama and 2) along a strong regional rainfall gradient in western Panama. All studied traits (e.g. velamen width, number of xylem poles, lignification of the exodermis) of the 45 orchid species showed substantial...
