Avian Influenza (H5N1) Expert System using Dempster-Shafer Theory [PDF]

open access: yesarXiv, 2012
Based on Cumulative Number of Confirmed Human Cases of Avian Influenza (H5N1) Reported to World Health Organization (WHO) in the 2011 from 15 countries, Indonesia has the largest number death because Avian Influenza which 146 deaths. In this research, the researcher built an Avian Influenza (H5N1) Expert System for identifying avian influenza disease ...

Sensitivity and Entanglement in the Avian Chemical Compass [PDF]

open access: yes, 2014
The Radical Pair Mechanism can help to explain avian orientation and navigation. Some evidence indicates that the intensity of external magnetic fields plays an important role in avian navigation. In this paper, based on a two-stage strategy, we demonstrate that birds could reasonably detect the directions of geomagnetic fields and gradients of these ...

Spatially structured genetic variation in a broadcast spawning bivalve: quantitative vs. molecular traits [PDF]

open access: yes, 2003
Understanding the origin, maintenance and significance of phenotypic variation is one of the central issues in evolutionary biology. An ongoing discussion focuses on the relative roles of isolation and selection as being at the heart of genetically based

Random Mating in a Hybrid Zone Between Two Putative Climate‐Adapted Bird Lineages With Predicted Mitonuclear Incompatibilities

open access: yesMolecular Ecology, Volume 34, Issue 2, January 2025.
ABSTRACT Biochemical and evolutionary interactions between mitochondrial and nuclear genomes (‘mitonuclear interactions’) are proposed to underpin fundamental aspects of biology including evolution of sexual reproduction, adaptation and speciation. We investigated the role of pre‐mating isolation in maintaining functional mitonuclear interactions in ...

A precise measure of avian magnetoreception based on quantum metrology [PDF]

open access: yesarXiv, 2016
The radical pair (RP) mechanism, which describes the quantum dynamics of a spatially separated electron pair, is considered as one of the principal models of avian magnetoreception. Different from the conventional phenomenological approach where the sensitivity of avian magnetoreception is characterized by the singlet yield $\Phi_{S}$, we introduce the

The role of mitochondrial DNA to determine the origin of domestic chicken [PDF]

open access: yes, 2015
Mitochondrial DNA (mtDNA) is has recently lost relevance especially when utilised to study species that are characterised with a history of several migrations.

Phylogeography, Historical Population Demography, and Climatic Modeling of Two Bird Species Uncover Past Connections Between Amazonia and the Atlantic Forest

open access: yesEcology and Evolution, Volume 14, Issue 12, December 2024.
We combined mitochondrial DNA sequence data and paleoclimatic distribution models to document phylogeographic patterns and investigate the historical demography of two manakins, Ceratopipra rubrocapilla and Pseudopipra pipra, as well as to explore connections between Amazonia and the Atlantic Forest.

A Unity of Science, Especially Among Physicists, Is Urgently Needed to End Medicine's Lethal Misdirection : Chapter 3. Prevention of the World Avian Flu Pandemic [PDF]

open access: yesarXiv, 2006
A very inexpensive simple procedure for protection of humans against avian flu that could blunt a pandemic is described.

Evolutionary associations between sand seatrout (Cynoscion arenarius) and silver seatrout (C. nothus) inferred from morphological characters, mitochondrial DNA, and microsatellite markers [PDF]

open access: yes, 2009
The evolutionary associations between closely related fish species, both contemporary and historical, are frequently assessed by using molecular markers, such as microsatellites.
