The dinosaur record of the Salitral Moreno locality (Río Negro Province, Argentina) is characterized by a high diversity of herbivore taxa, among them hadrosaurs, ankylosaurs, and titanosaur sauropods, but carnivores ar...

El presente estudio es una contribución más al conocimiento de la parataxonomía de las cáscaras de huevos de dinosaurios procedentes del Salitral de Santa Rosa y Salitral Ojo de Agua de la provincia de Río Negro, Ar...

The plasmasphere contains rich small-scale structure that plays a key role in regulating wave propagation and mass transport in the inner magnetosphere, yet the evolution of plasmaspheric density ducts remains poorly und...

The Gulf Coast region of Louisiana hosts one of the highest concentrations of petrochemical industries in the United States, contributing substantially to national economic output while simultaneously posing severe envir...

Shallow lakes often alternate between two possible states: one clear with submerged macrophytes, and another one turbid, dominated by phytoplankton. A third type of shallow lakes, the inorganic turbid, result from high c...

The objective of this study was to describe the morphological and anatomical features of five unidentified ectomycorrhizal types of Alnus acuminata and to complement their identification using ITS-DNA sequence analysis...

La coexistencia de especies ecológicamente similares es facilitada por el uso diferencial de recursos como el hábitat, la dieta y/o los gradientes temporales. Utilizamos heces de las especies no nativa conejo (Oryctola...

"The purpose of the present article is to investigate if there exist any such set of temporal stable patterns in temporal series of meteorological variables studying series of air temperature, wind speed and direction an...

Experiments were carried out in which the conditions of dendritic growth are known, as well as the velocity and direction of solidification, in alloy systems such as Al-Cu, Al-Mg, Al-Zn, Al-Li, Al-Si, Al-Si-Cu, Cu-Zn, Pb...

We study the effects of a Mars-like planetoid with a semimajor axis at about ∼60 AU orbiting embedded in the primordial Edgeworth–Kuiper belt (EKB). The origin of such an object can be explained in the framework of o...

Entre el Campaniano tardío y el Maastrichtiano temprano se produjo la ingresión del Mar de Kawas (Casamiquela, 1978), que inundó los valles fluviales patagónicos eliminando a sus pobladores estenohalinos. Los paleoam...
