A fossil assemblage from the lower Santa Rosita Formation at Quebrada de Abra Blanca, Jujuy Province, is described herein. Parabolina frequens argentina (Kayser) and Parabolinella coelatifrons Harrington & Leanza have previously been reported from other localities of the biozone, whereas Lotagnostus hedini (Troedsson) is here described from South America for the first time. The latter provides high resolution data on the age of the P . frequens argentina Zone in the eastern Cordillera Oriental, where conodont-bearing strata have not been found yet. L . hedini exhibits a short biostratigraphic range, restricted to the latest Furongian of China (Xinjiang, Bulbolenus Zone; western Zhejiang, Lotagnostus hedini Zone), Kazakhstan ( Euloma limitaris - Taoyuania Zone) and ?Canada (western Newfoundland, Phylacterus saylesi Fauna). In China and Kazakhstan, it occurs in association with, or a few meters below, the first appearance of the conodont Cordylodus proavus ; a fact that increases the potential for global correlation.","PeriodicalId":39176,"journal":{"name":"Revista del Museo Argentino de Ciencias Naturales, Nueva Serie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43144963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Efectuamos 36 medidas en 86 craneos de ejemplares adultos procedentes de Brasil. Realizamos la estadistica descriptiva con la cual comprobamos que en la mayoria de las medidas craneanas de los ejemplares machos y hembras de M. gouazoubira fueron un 5% mas grande. La excepcion fueron 3 medidas que presentaron mayor tamano en los ejemplares machos y hembras de M. nemorivaga . Este estudio permitio mediante los analisis multivariados de ANOVA y de Funcion Discriminante mostrar que existen diferencias significativas entre las dos taxa que validan la distincion de ambas especies. Para examinar con mas detalles la dinamica de la variacion de estos dos taxa es necesario aumentar el tamano de la muestra para poder analizar en el contexto geografico y genetico para poder determinar unidades prioritarias para la conservacion.","PeriodicalId":39176,"journal":{"name":"Revista del Museo Argentino de Ciencias Naturales, Nueva Serie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42689876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

En 1933 el destacado mastozoologo Jose V. Yepes estudio los especimenes colectados por Salvador Mazza y nomino una nueva especie: D. mazzai . Varios autores interpretaron que el holotipo era un ejemplar juvenil de D. novemcinctus . En 1995, Vizcaino acepto la sinonimia con D. novemcinctus , pero reconocio la existencia de una especie endemica del noroeste de Argentina que dedico a Yepes ( D. yepesi ) . La secuenciacion del mitogenoma de ejemplares del hipodigma de D. mazzai y estudios morfologicos han cuestionado la sinonimia de esta especie con D. novencinctus . En esta contribucion se reviso la identidad del material tipo secuenciando un fragmento de DNA de 212 bp, producto de la unidad ribosomal 16S de Dasypodidae. Ambas muestras del holotipo (hueso y musculo) y de un especimen del norte de Santa Fe presentan 100% de similitud con secuencias de D. yepesi / D. sabanicola disponibles en el GenBank. Los resultados indican que el ejemplar tipo de D. mazzai no es un juvenil de D. novemcinctus ni de otra de las especies del genero Dasypus previamente nominadas. Se revalida D. mazzai y se confirma el limite oriental, de su distribucion en la region chaquena.

Despite the need to cultivate it to decrease the extraction impact on its natural populations, the information on how environmental factors affect seed germinability is scarce. In order to evaluate the greminative response and the role of the antioxidant metabolism against saline stress, freshly collected seeds were germinated in the presence of 0 (control), 30, 60 or 90 mM NaCl. The percentage of germination, the content of soluble and carbonylated proteins, the activity of antioxidant enzymes and the generation of reactive oxygen species both in the pre-germination phase and during germination were evaluated. The removal of the aryl and the micropillar integument after 3 h imbibition proved to induce a rapid germination and activation of the enzymes catalase, glutathione S-transferase and peroxidases, together with an increase and a decrease in the generation of O 2 .- and H 2 O 2 , respectively, at the root apex. Even though the germination and activity of some of the studied enzymes decreased with the increase in external NaCl levels, when comparing populations of the control and 90 mM NaCl treatments having similar germination percentages, a marked induction of peroxidase activity was observed in the latter group. The proportion of carbonylated proteins did not differ among treatments, which suggests that, despite this species cannot be considered as halo-tolerant, the fact that the antioxidant metabolism efficiently contributed to prevent oxidative damage to the proteome may constitute an important mechanism to facilitate its establishment in environments with moderate salinity.","PeriodicalId":39176,"journal":{"name":"Revista del Museo Argentino de Ciencias Naturales, Nueva Serie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42993194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
