Assortative Mating By Diet In A Phenotypically Unimodal But Ecologically Variable Population Of Stickleback [PDF]

open access: yes, 2008
Speciation with gene flow may be driven by a combination of positive assortative mating and disruptive selection, particularly if selection and assortative mating act on the same trait, eliminating recombination between ecotype and mating type ...

Hyperfine Quenching of the $4s4p ^{3}P_{0}$ Level in Zn-like Ions [PDF]

open access: yes, 2007
In this paper, we used the multiconfiguration Dirac-Fock method to compute with high precision the influence of the hyperfine interaction on the $[Ar]3d^{10} 4s4p ^3P_0$ level lifetime in Zn-like ions for stable and some quasi-stable isotopes of nonzero ...

Comparison of different methods to determine the degree of peat decomposition in peat bogs [PDF]

open access: yesBiogeosciences, 2014
Peat humification or decomposition is a frequently used proxy to extract past time changes in hydrology and climate from peat bogs. During the past century several methods to determine changes in peat decomposition have been introduced.

Gamow-Teller strength distributions in Fe and Ni stable isotopes [PDF]

open access: yes, 2003
We study Gamow-Teller strength distributions in some selected nuclei of particular Astrophysical interest within the iron mass region. The theoretical framework is based on a proton-neutron Quasiparticle Random Phase Approximation built on a deformed ...

Onset of intruder ground state in exotic Na isotopes and evolution of the N=20 shell gap [PDF]

open access: yes, 2004
The onset of intruder ground states in Na isotopes is investigated by comparing experimental data and shell-model calculations. This onset is one of the consequences of the disappearance of the N=20 magic structure, and the Na isotopes are shown to play ...

Isotopes in hydrology and hydrogeology [PDF]

open access: yes, 2019
The structure, status, and processes of the groundwater system, which can only be acquired through scientific research efforts, are critical aspects of water resource management. Isotope hydrology and hydrogeology is a genuinely interdisciplinary science.

Fragmentation of exotic oxygen isotopes [PDF]

open access: yes, 2003
Abrasion-ablation models and the empirical EPAX parametrization of projectile fragmentation are described. Their cross section predictions are compared to recent data of the fragmentation of secondary beams of neutron-rich, unstable 19,20,21O isotopes at
