Biological clocks as age estimation markers in animals: a systematic review and meta‐analysis

Biological Reviews, Volume 98, Issue 6, Page 1972-2011, December 2023., 2023
ABSTRACT Various biological attributes associated with individual fitness in animals change predictably over the lifespan of an organism. Therefore, the study of animal ecology and the work of conservationists frequently relies upon the ability to assign animals to functionally relevant age classes to model population fitness.

Songbirds can learn flexible contextual control over syllable sequencing

eLife, 2021
The flexible control of sequential behavior is a fundamental aspect of speech, enabling endless reordering of a limited set of learned vocal elements (syllables or words). Songbirds are phylogenetically distant from humans but share both the capacity for

The carotenoid redshift: Physical basis and implications for visual signaling

Ecology and Evolution, Volume 13, Issue 9, September 2023., 2023
Carotenoid pigments appear redder as the concentration of a pigment increases. The carotenoid redshift arises due to the asymmetrical reflectance spectra of carotenoid‐colored ornaments and the exponential attenuation of light. Structures that increase the path length of light through carotenoid pigment also cause a redshift, as we demonstrate in the ...

Learning to pause: Fidelity of and biases in the developmental acquisition of gaps in the communicative signals of a songbird

Developmental Science, Volume 26, Issue 5, September 2023., 2023
Abstract The temporal organization of sounds used in social contexts can provide information about signal function and evoke varying responses in listeners (receivers). For example, music is a universal and learned human behavior that is characterized by different rhythms and tempos that can evoke disparate responses in listeners.

pykanto: A python library to accelerate research on wild bird song

Methods in Ecology and Evolution, Volume 14, Issue 8, Page 1994-2002, August 2023., 2023
Abstract Studying the vocalisations of wild animals can be a challenge due to the limitations of traditional computational methods, which often are time‐consuming and lack reproducibility. Here, I present pykanto, a new software package that provides a set of tools to build, manage, and explore large sound databases.

An Adapting Auditory-motor Feedback Loop Can Contribute to Generating Vocal Repetition.

PLoS Computational Biology, 2015
Consecutive repetition of actions is common in behavioral sequences. Although integration of sensory feedback with internal motor programs is important for sequence generation, if and how feedback contributes to repetitive actions is poorly understood ...

Long Memory in Song Learning by Zebra Finches [PDF]

, 2003
Young songbirds use memorized tutor songs as templates to shape their own songs. This process requires control of voice by auditory feedback. We prevented zebra finches from hearing their own vocalizations by exposure to loud noise after 35 d of age ...

Abnormal features of human self‐domestication in bipolar disorder

European Journal of Neuroscience, Volume 57, Issue 8, Page 1406-1431, April 2023., 2023
Abstract Bipolar disorder (BD) is a severe mental condition characterized by episodes of elevated mood and depression. Being a heritable condition, it features a complex genetic architecture, although it is not still clear how genes contribute to the onset and course of the disease.

Vocal learning promotes patterned inhibitory connectivity. [PDF]

, 2017
Skill learning is instantiated by changes to functional connectivity within premotor circuits, but whether the specificity of learning depends on structured changes to inhibitory circuitry remains unclear.

Self domestication and the evolution of language [PDF]

, 2018
We set out an account of how self-domestication plays a crucial role in the evolution of language. In doing so, we focus on the growing body of work that treats language structure as emerging from the process ofcultural transmission. We argue that a full
