Social information about others' affective states in a human‐altered world

open access: yesJournal of Animal Ecology, EarlyView.
Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective states to guide their decisions. Considering affective states of wild animals could have important implications for animal welfare and wildlife conservation ...

Analysis of CR1 Repeats in the Zebra Finch Genome [PDF]

open access: yesJournal of Systemics, Cybernetics and Informatics, 2013
Most bird species have smaller genomes and fewer repeats than mammals. Chicken Repeat 1 (CR1) repeat is one of the most abundant families of repeats, ranging from ~133,000 to ~187,000 copies accounting for ~50 to ~80% of the interspersed repeats in the ...

Discrimination of natural acoustic variation in vocal signals

open access: yesScientific Reports, 2021
Studies of acoustic communication often focus on the categories and units of vocalizations, but subtle variation also occurs in how these signals are uttered.

Environmental factors associated with nesting habits and age shape the composition and connection between skin and uropygial gland microbiomes of birds

open access: yesJournal of Animal Ecology, EarlyView.
This study provides new insights into how ecological conditions influence the evolution of host‐associated symbiotic communities and their functional roles. The findings suggest that pathogen pressures linked to nesting habits in birds shape bacterial communities of the uropygial gland, and their connection with the skin microbiome, where the ...

Observing the Zebra Finch

open access: yesThe American Biology Teacher, 1979
IANIMALS IN GENERAL and vertebrates in particular display little of their repertoire of behaviors in confined situations. Classroom observations of the behavior of Planaria, Daphnia, and Anolis often are less than rewarding for students. However, the problems encountered in observing organisms in their natural environments need not restrict the ...

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds

open access: yesJournal of Anatomy, EarlyView.
The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Molecular architecture of the zebra finch arcopallium

open access: yesJournal of Comparative Neurology, 2019
AbstractThe arcopallium, a key avian forebrain region, receives inputs from numerous brain areas and is a major source of descending sensory and motor projections. While there is evidence of arcopallial subdivisions, the internal organization or the arcopallium is not well understood.

Phylogenomics of the American robin (Turdus migratorius) reveals hidden lineages and introgression

open access: yesJournal of Systematics and Evolution, EarlyView.
Phylogenomic analyses of Turdus migratorius uncover four previously unrecognized lineages, including a divergent Baja California lineage (T. m. confinis). The results reveal complex evolutionary relationships that depart from simple models of continuous divergence, supported by evidence of introgression between the Mexican lineage and its previously ...

Writing Big in Plant Genomes: Advances, Challenges and Strategies for Targeted Large‐Fragment DNA Insertion

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Precise genome editing has transformed plant biology and crop improvement by enabling targeted modification of endogenous loci. Beyond gene knockout and base editing, the site‐specific insertion of exogenous DNA, particularly large DNA fragments, has become a central goal for engineering complex traits, reconstructing metabolic pathways and ...

Balanced imitation sustains song culture in zebra finches

open access: yesNature Communications, 2021
Studying how songbirds learn songs can shed light on the development of human speech. An analysis of 160 tutor-pupil zebra finch pairs suggests that frequency dependent balanced imitation prevents the extinction of rare song elements and the ...
