(Sociedad de Biología de Chile, 2008-06)During the last decades, limnological studies on Chilean systems have contributed to know the species composition and main environmental variables of many water bodies distributed over a wide latitudinal interval, from ...
-
(ELSEVIER, 2008-10-15)Herbivory may be an important factor affecting seedling survival of exotic species invading new habitats. We evaluated the effect of vertebrate herbivory on the seedling survival of two widely planted and invasive tree ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2008-03-15)The present work reports the synthesis and spectroscopic and electrochemical characterization of homoleptic copper(l) complexes with substituted pirazino [2,3-f]-1,10-phenanthroline, RpplR', (R = H, Me, COOH or COOMe, and ...
-
(ELSEVIER SCIENCE BV, 2008-12-09)Numerous physical and chemical agents can destroy mechanosensory hair cells in the inner ear of vertebrates, a process that is irreversible in mammals. Few experimental systems allow the observation of hair cell death ...
-
(SOC BIOLGIA CHILE, 2008)The secretion of proteinaceous toxins is a widespread characteristic in environmental and laboratory yeast isolates. a phenomenon called "killer system". The killer phenotype (K+) call be encoded by extrachromosomal genetic ...
-
(WILEY-V C H VERLAG GMBH, 2008-07)Both low-dimensional bar-coded metal oxide layers, which exhibit molecular hinging, and free-standing organic nanostructures can be obtained from unique nanofibers of vanadium oxide (VOx). The nanofibers are successfully ...
-
(ELSEVIER, 2008-06-11)Binding of MgATP to an allosteric site of Escherichia coli phosphofructokinase-2 (Pfk-2) provoked inhibition and a dimer-tetramer (D-T) conversion of the enzyme. Successive deletions of up to 10 residues and point mutations ...
-
(Sociedad de Biología de Chile, 2008-05-05)The cloning and nucleotide sequence of the genes (idi, crtE, crtYB, crtI and crtS) controlling the astaxanthin biosynthesis pathway of the wild-type ATCC 24230 strain of Xanthophyllomyces dendrorhous in their genomic and ...
-
(CAMBRIDGE UNIV PRESS, 2008-04)We consider Ledrappier's dynamical system, which was the first example of a Z(2)-action which is 2-mixing but not 3-mixing. Our main result is that, excluding certain small 'constructible' sets, the system is mixing of ...
-
(BIRKHAUSER VERLAG AG, 2008-12)It is known that classes of indefinite quadratic forms in a genus are classified by the Galois group of a spinor class field [4]. Hsia has proved the existence of a representation field F with the property that a lattice ...
-
(JOHN WILEY, 2008-08)Two new mulinane-type derivatives: 16-hydroxy mulin-11,13-dien-20-oic (2) acid and 7 alpha,16-dihydroxy mulin-11,13-dien-20-oic (3) acid were obtained by microbial transformation of mulin-11,13-dien-20-oic acid (1), along ...
-
(Springer Berlin / Heidelberg, 2008-07-15)According to the “barrel model”, an organism may be represented by a container, with input energy constraints (foraging, digestion, and absorption) symbolized by funnels connected in tandem, and energy outputs ...
-
(BIRKHAUSER VERLAG AG, 2008-09)We prove that, for all α > 0, every finitely generated group of C1+α diffeomorphisms of the interval with sub-exponential growth is almost nilpotent. Consequently, there is no group of C1+α interval diffeomorphisms having ...
-
(BIOMED CENTRAL LTD, 2008-10-06)Background: The yeast Xanthophyllomyces dendrorhous synthesizes astaxanthin, a carotenoid with high commercial interest. The proposed biosynthetic route in this organism is isopentenylpyrophosphate (IPP) -> geranyleranyl ...
-
(SOC MEXICANA FISICA, 2008-04)A systematic study of the colineal and no-colineal magnetic properties and the metallic behavior in free standing clusters of Pd-N (2 <= N <= 21) is carried out. We also study the effect of the twinning in clusters on the ...
-
(SPRINGER, 2008-03)Top-down and bottom-up mechanisms have been proposed as potential regulators of the phytoplankton biomass of aquatic ecosystems. We evaluated the effect of nutrient enrichment and planktivorous fish predation through a ...
-
(WILEY-LISS, DIV JOHN WILEY & SONS INC, 2006-06)The sensory organs of the zebrafish lateral-line system (neuromasts) originate from migrating primordia that move along precise pathways. The posterior primordium, which deposits the neuromasts on the body and tail of the ...
-
(BRILL ACADEMIC PUBLISHERS, 2006-03)Liolaemus pictus is a widely distributed arboreal lizard species in southern Chile. Within this species, mainland and island subspecies have been described mainly based on external morphological characters, however, their ...
-
(SPRINGER, 2006-11)Understory birds are especially vulnerable to habitat fragmentation because of the reduction in habitat quality and bird movement. We study the separate effects of understory, overstory and landscape on four understory ...
-
(BRILL ACADEMIC PUBLISHERS, 2006-07)Nest-mate recognition and territorial behaviour in ants are widely studied phenomena. However, few studies have analysed, under field conditions, how nest-mate recognition varies with distance from the resident's colony. ...
