Sclerites of Solenogastres: their formation and crystal organization
(Spixiana, 2022-07)Solenogastres are small-sized, elongate, cylindrical, worm-like molluscs, which have small calcified sclerites (spicules, spines and scales) embedded in their cuticle. They develop a ventral furrow with a short, rudimentary ... -
Secretome of epicardial-derived cells: extracellular vesicles and Matrix
(UMA Editorial, 2022)El epicardio es un conjunto de células epiteliales de origen extracardiaco y se incorpora a la superficie del corazón hasta envolver el miocardio. Estas células sufren un proceso de transición epitelio-mesénquima (TEM) por ... -
Shell-muscle attachment in the bivalves Ostrea stentina Payraudeau, 1826 and Anomia ephippium Linnaeus, 1758
(2019-10-07)The muscles of the mantle in bivalves attach to the shell valves and retract the mantle edges. Among them, the adductors are particularly important for the survival of the animal. Most studies have addressed the type and ... -
Spatial modelling for predicting potential wildlife distributions and human impacts in the Dja Forest Reserve, Cameroon.
(Elsevier, 2018-12-22)Protected areas (PAs) are currently the cornerstones for biodiversity conservation in many regions of the world. Within Africa's moist forest areas, however, numerous PAs are under significant threats from anthropogenic ... -
Species composition of sea stars (Echinodermata: Asteroidea) in the Patagonian Argentinian deep sea, including seven new records: connectivity with sub-Antarctic and Antarctic fauna
(Springer, 2022-06-28)The main target of this paper is to improve the knowledge of the species composition of sea stars in Patagonian Argentine deep sea reaching depths of 2062 m. In addition, these results offer us the opportunity to analyze ... -
Species distribution models as a useful tool in conservation programs: the case of the Northern Bald Ibis
(2018-06-26)The Northern Bald Ibis (Geronticus eremita) is one of the most endangered species on the planet. Over the last century, the species had suffered an extreme decline in its population size, and is now considered to be ... -
Species, Genera, Families and others, or the Naturality of Taxonomical Categories
(2015-10-19)Taxonomy, i.e. the science of classifying and naming organisms, has been an activity of man since the invention of language. However, the task of inventorying the Biodiversity on Earth is far from complete. With barely ... -
Taxonomic revision and molecular phylogeny of Pisa (Decapoda: Majoidea: Epialtidae), including the description of a new genus of Pisinae.
(CSIC, 2023-12-20)The spider crabs of the genus Pisa Leach, 1814 (Epialtidae: Pisinae) are reviewed in this study based on mor- phological and molecular data (16S and COI genes). From these results, a new genus, Afropisa n. gen., is established ... -
Tendencias de una población de jabalí con hibridación sometida a control letal.
(2023)El jabalí (Sus scrofa) es una especie ampliamente distribuida en Europa y en muchas zonas se ha convertido en una especie muy abundante, lo que ha aumentado las interacciones negativas con el hombre. Su presencia en zonas ... -
Tendencias en dos poblaciones de cánidos silvestres tras 14 años de seguimiento en un área protegida recientemente ampliada en la Patagonia Austral Argentina
(2018-10-15)El seguimiento de las poblaciones de fauna silvestre es clave para conservar la biodiversidad, así como para comprender el funcionamiento de los ecosistemas. Permite tomar decisiones de gestión adecuadas a las tendencias ... -
Terapia celular antiparkinsoniana con cuerpo carotídeo
(2015-10-27)La terapia celular es una terapia avanzada en la que las células pueden ser usadas como auténticos medicamentos. Como elemento esencial de la medicina regenerativa, el objetivo principal de estas terapias es la sustitución ... -
Terrestrial Megafauna Response to Drone Noise Levels in Ex Situ Areas
(IOAP-MPDI, 2022-10-30)Drone use has significantly grown in recent years, and there is a knowledge gap on how the noise produced by these systems may affect animals. We investigated how 18 species of megafauna reacted to drone sound pressure ... -
Testing for errors in estimating bird mortality rates at wind farms and power lines
(CAMBRIDGE UNIVERSITY PRESS, 2017)Wind power, as an alternative to fossil fuels, is increasingly common, and is expanding worldwide. Wind farms cause mortality of flying animals through collision with moving rotor blades, and from electrocution on associated ... -
The anatomical components of the cardiac outflow tract of chondrichthyans and actinopterygians
(Cambridge University Press, 2018)The outflow tract (OF) of the fish heart is the segment interposed between the ventricle and the ventral aorta. It holds the valves that prevent blood backflow from the gill vasculature to the ventricle. This paper offers ... -
The anatomical components of the cardiac outflow tract of the bichir, polypterus senegalus. Evolutionary significance
(2013-07-26)In chondrichthyans and actinopterygians, the outflow tract of the heart, namely, the cardiac portion intercalated between the ventricle and the ventral aorta, consists of two anatomical components: conus arteriosus and ... -
The biogeographic basis of Ebola-virus disease outbreaks: A model for other zoonotic diseases?
(2017-08-29)We first determined the differential role of favorability of environmental conditions and mammalian chorotypes in explaining the presence of the Ebola virus in Africa. We then combined environmental factors and chorotypes ... -
The bulbus arteriosus of the holocephalan heart
(2013-07-25)Previous work has shown that the outflow tract of the elasmobranch heart, namely the cardiac portion intercalated between the ventricle and the ventral aorta, does not consist of a single component, the conus arteriosus, ... -
