Characterization of complete mitochondrial genome of the Brown Accentor Prunella fulvescens on the Tibet Plateau

open access: yesMitochondrial DNA. Part B. Resources, 2017
The Brown Accentor (Prunella fulvescens) is a poorly known bird species distributed in Eurasia high-montane areas. In this paper, we described the whole mitochondrial genome of the Brown Accentor.

Sexually size dimorphic brains and song complexity in passerine birds [PDF]

open access: yes, 2004
Neural correlates of bird song involve the volume of particular song nuclei in the brain that govern song development, production, and perception. Intra- and interspecific variation in the volume of these song nuclei are associated with overall brain ...

Long-distance dispersal patterns in the Cerulean Warbler: a case study from Indiana

open access: yesAvian Conservation and Ecology, 2023
Dispersal, defined as movement an individual makes from one breeding population to another, is a process that strongly influences the population dynamics of many animal species.

Diet of breeding Eleonora's falcon Falco eleonorae in Algeria: Insights for the autumn trans‐Mediterranean avian migration

open access: yesEcology and Evolution, 2022
How environmental changes are affecting bird population dynamics is one of the most challenging conservation issues. Dietary studies of top avian predators could offer scope to monitor anthropogenic drivers of ecosystem changes.

Passerine swarm optimization algorithm for solving optimal reactive power dispatch problem [PDF]

open access: yes, 2020
This paper presents Passerine Swarm Optimization Algorithm (PSOA) for solving optimal reactive power dispatch problem. This algorithm is based on behaviour of social communications of Passerine bird. Basically, Passerine bird has three common behaviours:

Sperm morphology and function in passerine birds: insights from intra- and interspecific studies [PDF]

open access: yes, 2010
Sperm cells are the most variable animal cells, and a tremendous variation in sperm phenotypes exists among species, from minute amoeboid sperm to giant sperm in some species of fruit flies.

The predictive power of pollination syndromes: Passerine pollination in heterantherous Meriania macrophylla (Benth.) Triana (Melastomataceae)

open access: yesEcology and Evolution, 2021
The cloud forest species Meriania macrophylla (Benth.) Triana has pseudocampanulate flowers with bulbous stamen appendages, typical for the passerine pollination syndrome found in the Melastomataceae tribe Merianieae. The species is further characterized

A novel gene organization of the rock sparrow Petronia petronia (Aves: Passeriformes) revealed by complete mitochondrial genome

open access: yesMitochondrial DNA. Part B. Resources, 2017
The whole sequence of the Rock Sparrow (Petronia petronia) mitochondrial genome was determined using La-PCR and conserved primer walking approaches. The entire mitogenome was 17,426 bp in length and harboured 13 protein-coding genes, 2 rRNA genes, 23 ...

Mitochondrial Gene Diversity and Host Specificity of Isospora in Passerine Birds

open access: yesFrontiers in Veterinary Science, 2022
Isospora infections are common in both wild and captive passerine species. Many bird species have been shown to have co-evolved with a particular species of Isospora.
