Discrimination of natural acoustic variation in vocal signals
Studies of acoustic communication often focus on the categories and units of vocalizations, but subtle variation also occurs in how these signals are uttered.

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 ...

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

Molecular architecture of the zebra finch arcopallium
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.

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 ...

Classifying avian drinking behaviour: ecological insights and implications in a changing world
ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns

Based on data from over 550 great tit (Parus major) eggs collected in the city mosaic, this research finds no effect of urbanisation on egg volume or pigmentation patterns. These results suggest that urban‐driven environmental pressures may not be as strong or directional during the egg laying phase as they are at later stages of reproduction ...

Balanced imitation sustains song culture in zebra finches
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 ...

NONLINEAR DYNAMICS AND THE SYNTHESIS OF ZEBRA FINCH SONG
Behavior emerges as the interaction between a nervous system, a peripheral biomechanical device and the environment. In birdsong production, this observation is particularly important: songbirds are an adequate animal model to unveil how brain structures reconfigure themselves during learning of a complex behavior as song. Therefore, it is important to

Infant survival of wild Verreaux's sifakas was impacted by different cumulative indices of early adversities. Of the single factors, maternal loss, large group size and the absence of an older sibling decreased the odds of survival across the lifespan. Adversities early in life have persistent negative long‐term effects on survival.
