Wolf‐Dog Hybrids Are More Fearful but as Social and Playful as Dogs
Ethology, Volume 131, Issue 10, Page 187-197, October 2025.In order to understand how behavior changed during dog domestication, we used wolf‐dog hybrids as a proxy for wolves and compared their behavior in several test situations with that of the dog breeds they were mixed with. Wolf‐dog hybrids were similar to the dogs in sociability, playfulness, and aggression, but showed significantly more long‐lasting ...

Sexual Differences in Cell Loss during the Post-Hatch Development of Song Control Nuclei in the Bengalese Finch. [PDF]
PLoS ONE, 2015 Birdsongs and the regions of their brain that control song exhibit obvious sexual differences. However, the mechanisms underlying these sexual dimorphisms remain unknown.

Past research and future directions in understanding how birds use their sense of smell
Ibis, Volume 167, Issue 4, Page 853-881, October 2025.Our understanding of the functional importance of olfaction to birds has improved over the past 60 years, largely as the result of experimental studies testing how birds use their sense of smell in different contexts. As it is impossible to measure directly which odours birds can detect, we rely on measuring behavioural responses to scent cues or ...

Diet and birdsong: short‐term nutritional enrichment improves songs of adult Bengalese finch males
Journal of Avian Biology, 2016 Song is a notable sexual signal of birds, and serves as an honest indicator of male quality. Condition dependence of birdsong has been well examined from the viewpoint of the developmental stress hypothesis, which posits that complex songs assure fitness

Ibis, Volume 167, Issue 4, Page 1028-1042, October 2025.Bird song is an important and variable sexual signal in many passerine species. One function of this variability may be that males show mate choice and can alter their song according to the quality of the female to which they are singing. If attractive songs are costly, we can hypothesize that males sing more attractively or invest more in singing when

PLoS ONE, 2021 Production and perception of birdsong critically depends on early developmental experience. In species where singing is a sexually dimorphic trait, early life song experience may affect later behavior differently between sexes. It is known that both male

Reduced Adult Neurogenesis in Humans Results From a Tradeoff Rather Than Direct Negative Selection
BioEssays, Volume 47, Issue 9, September 2025.Embryonic radial glia (RG) generate neurons, glial cells, and later adult neural stem cells, which sustain adult neurogenesis (top, left to right). Human‐specific genetic modifications (blue arrow), selected to boost early RG neurogenic activity, may lead to premature RG exhaustion and reduced adult neurogenesis in the human brain (bottom).

Ecology and Evolution, Volume 15, Issue 9, September 2025.How do birds develop their unique vocal repertoires, and how do these vary across populations? Using machine learning and bioacoustics, we analyzed the vocalizations of the White Spectacled Bulbul, revealing population‐specific motifs built from shared syllables.
