(SOC NEUROSCIENCE, 2010-01-11)The lateral line system of teleosts has recently become a model system to study patterning and morphogenesis. However, its embryonic origins are still not well understood. In zebrafish, the posterior lateral line (PLL) ...
-
(Sociedad Mexicana de Fisica, 2014)A mechanism that produces conical dispersion relations is presented. A Kronig Penney one dimensional array with two different strengths delta function potentials gives rise to both the gap closure and the dispersion relation ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005-05)We addressed phylogenetic relationships in the genus Trachurus using cytochrome b gene and D-loop sequences. The trees showed five groups: (1) the Southwest Pacific species (T. japonicus, T. novaezelandiae, and T. declivis); ...

-
(ROYAL SOC CHEMISTRY, 2016)The mechanism of the ANRThe mechanism of the ANRORC-like ring transformation of nitroimidazole derivatives towards aniline has been studied by fully exploring the potential energy surface (PES). For this purpose the reaction ...
-
(Universidad de Chile, 2008)La presencia de especies congéneres de invertebrados marinos bentónicos en Antártica y Sudamérica, ha sido históricamente interpretado como el resultado del proceso de vicarianza, consecuencia de la separación de ambos ...

Osmoregulation and adaptive radiation in the ovenbird genus Cinclodes (Passeriformes : Furnariidae) (BLACKWELL, 2006-10)1. The genus Cinclodes is unique among passerines because it includes two species that can be considered marine/coastal and also includes several species that inhabit freshwater streams or that shift habitats between ...

(Elsevier, 2013)Recent experiments on shorebirds have demonstrated that maintaining an active osmoregulatory machinery is energetically expensive. This may, in part, explain diet and habitat selection in birds with salt glands. However ...
-
(Sociedad de Biologia de Chile, 2007)We studied the osmoregulatory responses of the granivore Zonotrichia capensis, acclimated to high- and low-protein diets as well as two levels of water intake. We tested whether Z. capensis has the ability to modify the ...
-
(Taylor & Francis, 2018)The upper Maastrichtian elasmosaurid plesiosaur Aristonectes quiriquinensis from central Chile is here redescribed following further preparation of the holotype. New cranial characters include a flattened skull with a ...
-
(SPRINGER, 2007-03)Most studies on the fitness advantage of outbreeding in host–parasite systems have been assessed from the host rather than the parasite perspective. Here, we performed experimental pollination treatments to evaluate the ...

-
(Elsevier, 2020)Based on discussions held at a workshop in Bra-Pollenzo, Italy, this paper elaborates upon 19 outstanding questions of plasma physics in the Earth’s magnetosphere. The questions are grouped according to (a) driving processes, ...

(1996)Objective: There is no endocrine test which is completely reliable for the confirmation of Cushing's syndrome and in separation of the various aetiologies. We have tested the hypothesis that overnight dexamethasone ...
-
(Elsevier, 2015)The cryptic concept refers to two or more species that have been classified as a single nominal species due to the fact that they are apparently morphologically indistinguishable. In recent years, the development of ...
-
(2003)This paper describes the history of cephalopod fisheries in Chile over the past 40 years. Continuous monitoring of three species was undertaken between 1978 and 1999: Loligo gahi, Dosidicus gigas and Octopus mimus. Total ...
-
(Blackwell, 2019)How animal-pollinated plants support low and stochastic pollination in the high alpine is a key question in plant ecology. The ovule bet-hedging hypothesis proposes compensation for stochastic pollination via ovule oversupply ...
-
(Springer, 2016)In this study, a glassy carbon electrode modified with different cobalt glucosamines (CoGlu-R), iron glucosamines (FeGlu-R), and nickel glucosamines (NiGlu-R) was used for the electroanalytical determination of melatonin ...
