On the advantage of sharing a holdfast: effects of density and occurrence of kin aggregation in the kelp Lessonia berteroana
(2014)
We investigated the density-dependent and genetic relatedness that regulate the occurrence of inter-individual (genet) fusion forming plurigenotypic organisms in the brown alga Lessonia berteroana. Recruitment generally ...
Mechanisms affecting population density in fragmented habitat
(RESILIENCE ALLIANCE, 2005-06)
We conducted a factorial simulation experiment to analyze the relative importance of movement pattern, boundary-crossing probability, and mortality in habitat and matrix on population density, and its dependency on habitat ...
Improved electron density measurements at Jicamarca
(American Geophysical Union, 2007-11-27)
Taking into account the effects of electron Coulomb collisions, incoherent scatter (IS) radar cross sections for probing angles close to perpendicular to the magnetic field have been calculated and used to correct backscattered ...
Electron momentum density and Compton profile by a semi-empirical approach
(Elsevier, 2015-03)
Here we propose a semi-empirical approach to describe with good accuracy the electron momentum densities and Compton profiles for a wide range of pure crystalline metals. In the present approach, we use an experimental ...
A study of the relationships between unpaired electron density, spin-density and cumulant matrices
(Springer, 2011-02)
This work describes the derivation of simple relationships between the density matrix of effectively unpaired electrons and the spin-density matrix in N-electron systems. The link between both devices turns out to be the ...
Practice of martial arts and bone mineral density in adolescents of both sexes
(2016-06-01)
Objective The purpose of this study was to analyze the relationship between martial arts practice (judo, karate and kung-fu) and bone mineral density in adolescents. Methods The study was composed of 138 (48 martial arts ...
Effect of quality control, density and allele frequency of markers on the accuracy of genomic prediction for complex traits in Nellore cattle
(2017-12-01)
This study was designed to test the impact of quality control, density and allele frequency of single nucleotide polymorphisms (SNP) markers on the accuracy of genomic predictions, using three traits with different ...
EFFECT OF DENSITY AND FLOWER SIZE ON THE REPRODUCTIVE SUCCESS OF NOTHOSCORDUM GRAMINUM (ALLIACEAE)
(Facultad de Ciencias Naturales y Oceanográficas, Universidad de Concepción, 2006)
