THE STRENGTH AND TIMING OF THE MITOCHONDRIAL BOTTLENECK IN SALMON SUGGESTS A CONSERVED MECHANISM IN VERTEBRATES.

The strength and timing of the mitochondrial bottleneck in salmon suggests a conserved mechanism in vertebrates.

In most species mitochondrial DNA (mtDNA) is inherited maternally in an apparently clonal fashion, although how this is achieved remains uncertain.Population genetic studies show not only that individuals can harbor more than one type of mtDNA (heteroplasmy) but that heteroplasmy is common and widespread across a diversity of taxa.Females harboring

The chirality-flow formalism

Abstract We take a fresh look at Feynman diagrams in the spinor-helicity formalism.Focusing on tree-level massless QED and QCD, Fashion Dresses we develop a new and conceptually simple graphical method for their calculation.In this pictorial method, which we dub the chirality-flow formalism, Feynman diagrams are directly Glucosamine represented in

A multi-level analysis of links between government institutions and community-based conservation: insights from Iran

Community-based conservation (CBC) is widely recognized as an important strategy (locally, nationally, and internationally) in efforts to conserve biodiversity.This article examines approaches to improve the effectiveness of CBC by resolving tensions between government institutions and local communities, in terms of respective environmental steward
