The effect of neighborhood size on effective population size in theory and in practice [PDF]
Heredity, 2016 The distinction between the effective size of a population (Ne) and the effective size of its neighborhoods (Nn) has sometimes become blurred. Ne reflects the effect of random sampling on the genetic composition of a population of size N, whereas Nn is a measure of within-population spatial genetic structure and depends strongly on the dispersal ...

Individual increase in inbreeding allows estimating effective sizes from pedigrees
Genetics Selection Evolution, 2008 We present here a simple approach to obtain reliable estimates of the effective population size in real world populations via the computation of the increase in inbreeding for each individual (delta Fi) in a given population.

The effect of shear-dependent flocculation on the multimodality of effective particle size distributions in a gravel-bed river during high flows [PDF]
, 2023 Purpose Multimodal effective particle size distributions (EPSDs) develop as flocculation and particle breakage occur dynamically in a fluid shear and such distributions have been previously reported in coastal and estuarine waters to understand ...

Size dependent of the effective conductivity of composite with imperfect interfaces
Vietnam Journal of Mechanics, 2020 Based on the circle assemblage model, the effective properties of the inclusion with imperfect interface are derived. The equivalent inclusion is incorporated in the Fourier Transform algorithm to determine the effective conductivity of the composite ...

Effective population size in Busha and Gatačko cattle from Herzegovina: Ecological and molecular approach [PDF]
Agroznanje, 2013 The effective population size (Ne) is one of basic core concepts in population genetics. Monitoring the effective population size, which is parallel to monitoring genetic variability, is of importance to population genetic studies and is applicable in ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
