Identification of Birds through DNA Barcodes [PDF]

open access: yes, 2004
Short DNA sequences from a standardized region of the genome provide a DNA barcode for identifying species. Compiling a public library of DNA barcodes linked to named specimens could provide a new master key for identifying species, one whose power will ...

Serotonergic neurons in the ventral nerve cord of Chilopoda – a mandibulate pattern of individually identifiable neurons

open access: yesZoological Letters, 2017
Background Given the numerous hypotheses concerning arthropod phylogeny, independent data are needed to supplement knowledge based on traditional external morphology and modern molecular sequence information.

Role of the Setae in an Ectoparasitic Seal Louse in Reducing Surface Drag: Numerical Modeling Approach

open access: yesAdvanced Theory and Simulations, Volume 8, Issue 10, October 2025.
The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design

Metabarcoding Close to Home: Songbird Nests as eDNA Aggregators for Trophic Ecology and Biodiversity Studies

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We present a novel method for extracting eDNA from whole bird nests and a LNA blocking oligonucleotide designed to reduce metabarcoding reads from nest building sparrows. Metabarcoding of 22 nests from a montane sagebrush steppe ecosystem detected 126 species, primarily insects, including putative diet items, ectoparasites, and confirmed nest predators.

Transcriptomic Analysis and Comparative Analysis of Gene Families Related to Environmental Adaptation in Two Grylloblattodea Species: Galloisiana sinensis and Grylloprimevala jilina

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
Notoptera, a singular ancient insect lineage, is vital for exploring insect environmental adaptation, evolution, and its geological history link, recognized as a national first‐class protected animal. Comparing environmental adaptation genes in Galloisiana sinensis and Grylloprimevala jilina, closely related yet habitat‐disparate species, illuminates ...

Insufficient Logging Intervals Impede Upper Soil Recovery in Temperate Beech Forests: Insights From Two Case‐Studies in Poland

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
This study examined the effects of forest operations on soil microarthropod biodiversity and litter decomposition in temperate beech forests, comparing disturbed and undisturbed soils across different harvesting timelines. While litter decomposition remained unaffected, significant soil disturbances were found in areas impacted by machine passage, with

Exploring the Mitogenomes of Acroneuriinae: The First Report of Gene Rearrangements in Plecoptera Species and Phylogenetic Analyses of Perlidae

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
First reported gene rearrangements in plecopteran mitogenomes. The monophyly of the subfamily Acroneuriinae and the phylogenetic relationships among tribes within this subfamily are still controversial. ABSTRACT Perlidae represents one of the most diverse and ecologically important groups within the order Plecoptera.
