(Soc Neuroscience, 2016)Physiological levels of ROS support neurite outgrowth and axonal specification, but the mechanisms by which ROS are able to shape neurons remain unknown. Ca2+, a broad intracellular second messenger, promotes both Rac1 ...
-
(Ecological Society of America, 2014)© 2014 by the Ecological Society of America. We test the validity of applying the alternative stable state paradigm to account for the landscape-scale forest/non-forest mosaic that prevails in temperate Tasmania, Australia. ...
-
(IOP Publishing, 2020)Depending on the physical conditions involved, beam plasma systems may reveal new unstable regimes triggered by wave instabilities of different natures. We show through linear theory and numerical simulations the existence ...
-
(Cambridge Univ Press, 2021)Darwin's frogs Rhinoderma darwinii and Rhinoderma rufum are the only known species of amphibians in which males brood their offspring in their vocal sacs. We propose these frogs as flagship species for the conservation of ...
-
(1999)We present a simple non-radioactive cytometry-based assay that permits the simultaneous quantitation of cell adhesion of distinct subsets of cells contained in a mixture without any previous fractionation. The procedure ...
-
(Universidad de Chile., 2021)A global climate component we faintly understand is the Southern Westerly Winds (SWW). Long-term SWW trends play a major role in determining Southern South American precipitation and fire regimes, deep-sea CO2 ventilation, ...
-
(Springer, 2017)Countries that are signatories of the Convention of Biological Diversity are committed to the goal of protecting 17% of their natural ecosystems by 2020. The lack of an up-to-date, operational classification and cartography ...
-
(GENETICS SOC AM, 2009-09-03)The Drosophila melanogaster wing is a model system for analyzing the genetic control of organ size, shape, and pattern formation. The formation of the wing involves a variety of processes, such as cell growth, proliferation, ...
-
(2008)Let G be a finite group, Λ an absolutely irreducible ℤ[G]-module and w a weight of Λ. To any Galois covering with group G we associate two correspondences, the Schur and the Kanev correspondence. We work out their relation ...
-
(2012)This essay attempts to capture the spirit of our recent meeting in Chile entitled "Emerging Concepts in Neuronal Cytoskeleton." The purpose of the meeting was to bring together scientists from South American countries with ...
-
(2011)There is great interest in understanding how extremophilic biomining bacteria adapt to exceptionally high copper concentrations in their environment. Acidithiobacillus ferrooxidans ATCC 53993 genome possesses the same ...
-
(Elsevier, 2019)Aristonectines show a highly derived morphology among elasmosaurid plesiosaurs, including some species with large body size. A new postcranial skeleton is described from the uppermost Maastrichtian levels of the L opez ...
-
(Nature, 2020)Egg size and structure reflect important constraints on the reproductive and life-history characteristics of vertebrates(1). More than two-thirds of all extant amniotes lay eggs(2). During the Mesozoic era (around 250 ...
-
(American Mathematical Society, 2005)For a family of single-species delayed population models, a new global stability condition is found. This condition is sharp and can be applied in both monotone and nonmonotone cases. Moreover, the consideration of variable ...
-
(1990)The aerial parts of Bahia ambrosioides afforded several germacranolides and heliangolides one of which has not been reported previously. Furthermore, in addition to widespread compounds, four 3-hydroxyumbelliferone derivatives ...
-
(Kluwer Academic Publishers, 1987)Questions of successional pattern and causality have been central concerns in vegetation ecology. In this paper we address the limits of the overextended models of Connell and Slatyer by discussing problems encountered in ...
-
(BIOMED CENTRAL LTD, 2010-12-22)Background: Studies on innate immunity have benefited from the introduction of zebrafish as a model system. Transgenic fish expressing fluorescent proteins in leukocyte populations allow direct, quantitative visualization ...
-
(2010)The analysis of a 10 000 calendar year (cal. ka) pollen record on the west coast of Tasmania has revealed a suite of changes that can be related to sea level, fire and people. Fire-promoted moorland has occupied the site ...
-
(AMER INST PHYSICS, 2011-01)Based on the one-body particle-antiparticle Dirac theory of electrons, a set of relativistic quantum fluid equations for a spin half plasma is derived. The particle-antiparticle nature of the relativistic particles is ...
