Study of a New Population of the Argentinian Endemic Species Riella choconensis Hässel (Riellaceae, Marchantiophyta) Reveals a Novel Anatomical Struc…

2019

A new population of the Argentinian endemic Riella choconensis Hässel (Riellaceae, Marchantiophyta) was discovered from a culture of sediments from the Laguna de los Juncos (Río Negro province, Argentina). This species was known previously from two nearby collections, made in 1984, in the type locality at the Ramos Mexía reservoir (Neuquén province) and was not recorded since. Fresh material from the new population enabled detailed morphological analyses, which are extensively described here, illustrated and compared to type material of the species. Based on the smooth female involucre, the species belongs to subgenus Riella Mont. However, cross-sections of this structure showed that R. cho…

During the examination of a collection made by the authors in 2009 in San Pedro de Atacama (Antofagasta Region, Chile) one specimen was identified as Bryum incacorralis Herzog, a moss not previously known from Chile (Müller, 2009) and easily confused with some species of Philonotis Brid. (Ochi, 1980). Comparison with the type material confirmed its identity (Holotype: Bolivia, Cochabamba: an Felsen der "Estradillas" bei Incacorral, 3000 m, Herzog s.n., JE! no. 04003475). Bryum incacorralis was first described by Herzog (1909) based on material collected in Cochabamba (Bolivia), and later recorded by Griffin (1977) and O'Shea (2010) from Venezuela. It is placed in the so-called sect. "Alpini…

In the moss flora of Uruguay there are recorder ten species of genus Fissidens (Matteri, 2004). Three of them (F. macrobryoides, F. prionocheilos and F. vitreo-limbatus) are species incertae because the type material for the names not was located (Purssel, 2007). As part of project "Studies on Bryophytes in the Cone Sur (Systematic and Phylogeny)" some specimens recently collected in Uruguay were determinate as Fissidens asplenioides a no previously species recorded in this country. The presence of F. asplenioides in Uruguay complete the distribution range of the species in the cone Sur (is present in Argentina, Bolivia, Brazil, Chile and Paraguay). However, within the Neotropical region th…

Defense Responses in Two Ecotypes of Lotus japonicus against Non-Pathogenic Pseudomonas syringae

2013

Lotus japonicus is a model legume broadly used to study many important processes as nitrogen fixing nodule formation and adaptation to salt stress. However, no studies on the defense responses occurring in this species against invading microorganisms have been carried out at the present. Understanding how this model plant protects itself against pathogens will certainly help to develop more tolerant cultivars in economically important Lotus species as well as in other legumes. In order to uncover the most important defense mechanisms activated upon bacterial attack, we explored in this work the main responses occurring in the phenotypically contrasting ecotypes MG-20 and Gifu B-129 of L. ja…

Prácticas docentes para la zoología y botánica en los nuevos planes de estudio.1.

2009

Nuestra propuesta intenta promover el uso de las TIC´s (tecnologías de la información y la comunicación) en las clases prácticas de Zoología y Botánica (dos materias obligatorias para estudiantes de 2º curso de Biología y de Ciencias Ambientales) a través del uso de un DVD interactivo que contiene los materiales para las dos sesiones prácticas, el estudio de la morfología funcional del cráneo de los mamíferos y una salida al campo virtual a un área protegida para reconocer plantas y animales comprendiendo sus relaciones ecológicas en los diferentes hábitats. En el ámbito universitario, estas herramientas informáticas, se pueden emplear como ayuda pedagógica antes o después de la asistencia …
