Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

ANTARCTICA AS BACKGROUND FOR MAMMALIAN EVOLUTION

open access: yesPublicación Electrónica de la Asociación Paleontológica Argentina, 2015
. Since the 1980's, a series of new Cretaceous-Paleogene land mammals has been found in southern continents. They drastically changed the traditional perspective of how mammals evolved all over the world, and particularly, how they evolved in the ...

Urbanization and Vector Species Shape Avian Malaria Prevalence in Mosquitoes

open access: yesIntegrative Zoology, EarlyView.
Avian malaria prevalence was assessed in two mosquito species across urban and peri‐urban habitats. No infections were detected in either species in urban areas, while a 2.53% prevalence was found in the native Culex pipiens from peri‐urban sites, highlighting the influence of urbanization on parasite transmission dynamics.

The Troubles and Beyond: The impact of a museum exhibit on a post‐conflict society

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract In divided societies, can museums contribute to healing and recovery? While efforts to memorialize past violence typically aim to promote tolerance and reconciliation, remembering could exacerbate divisions in recovering societies where the past is deeply contested. We examine a transitional justice museum exhibit in Northern Ireland.

Getting on the grid: A field experiment on bottom‐up political pressure and access to essential public services

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Water is essential for human life, yet governments frequently leave vulnerable citizens to rely on informal channels for access. What can motivate governments to provide public services such as water to citizens trapped in informality?

LOS MAMÍFEROS DE LA FORMACIÓN FRAY BENTOS (EDAD MAMÍFERO DESEADENSE, OLIGOCENO SUPERIOR?) DE LAS PROVINCIAS DE CORRIENTES Y ENTRE RÍOS, ARGENTINA

open access: yesPublicación Electrónica de la Asociación Paleontológica Argentina, 2015
The Fray Bentos Formation, with outcrops in the Uruguayan and the Argentinean provinces of Corrientes and Entre Ríos, has yielded several fossil vertebrates, mainly mammals, that permit its reference to the Deseadan land-mammal age (upper Oligocene?). At

Fatty Acid Signaling Mechanisms in Neural Cells: Fatty Acid Receptors

open access: yesFrontiers in Cellular Neuroscience, 2019
Fatty acids (FAs) are typically associated with structural and metabolic roles, as they can be stored as triglycerides, degraded by β-oxidation or used in phospholipids’ synthesis, the main components of biological membranes. It has been shown that these

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.
