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.

Morphology and biomechanics of the nests of the Common Blackbird Turdus merula [PDF]

open access: yes, 2015
Capsule Common blackbirds select different materials, with varying biomechanical properties, to construct different parts of their nest. Aims This study tested the hypothesis that outer components of a nest have a more structural role and so are ...

A comparative study of the function of heterospecific vocal mimicry in European passerines [PDF]

open access: yes, 2007
Although heterospecific vocal imitation is well documented in passerines, the evolutionary correlates of this phenomenon are poorly known. Here, we studied interspecific variation in vocal mimicry in a comparative study of 241 European songbirds.

Bird pollination of Canary Island endemic plants [PDF]

open access: yes, 2008
The Canary Islands are home to a guild of endemic, threatened bird pollinated plants. Previous work has suggested that these plants evolved floral traits as adaptations to pollination by flower specialist sunbirds, but subsequently they appear to be ...

Using large-scale citizen science ringing data as a means of calculating maximum longevity in birds

open access: yesBothalia: African Biodiversity & Conservation, 2019
This article calculates estimates of avian longevity for southern African Passeriformes and demonstrates the impact citizen scientists have on data volumes curated by the South African Bird Ringing Unit (SAFRING).

Avian Malaria Among House Sparrows: a Survey of Disease and Mosquito Vectors (Diptera: Culicidae) in Reed City, Michigan [PDF]

open access: yes, 2017
Nine of 350 house sparrows caught in Reed City, Michigan, had malaria parasites detectable on Giemsa-stained thin films. All of the infected birds were juveniles, Parasitemias were too low to permit identification of the Plasmodium present. Collection of

Diet contributes to urban-induced alterations in gut microbiota : experimental evidence from a wild passerine [PDF]

open access: yes, 2020
Urban sprawl increasingly affects the ecology of natural populations, including host-microbiota interactions, with observed differences in the gut microbiota between urban and rural hosts.

Testing the causal mechanism of the peninsular effect in passerine birds from South Korea.

open access: yesPLoS ONE, 2021
The peninsular effect is a geographical phenomenon that explains patterns of species richness. Given that spatial variation in species richness along a peninsular may be driven by multiple processes, we aimed to identify the sources of latitudinal ...

Testing macroevolutionary predictions of the Grant-Stebbins model in the origin of Aeschynanthus acuminatus. [PDF]

open access: yesNew Phytol
Summary The Grant‐Stebbins model predicts that a plant species encountering different pollinators across its range may undergo local adaptation and, subsequently, ecological speciation. We tested whether this could explain the origin of Aeschynanthus acuminatus (Gesneriaceae), a species phylogenetically derived from sunbird specialist ancestors.
