Evolução e organização genômica do gene FOXL2 em vertebrados
(Universidade Estadual Paulista (Unesp), 2012-07-30)
FOXL2 representa um importante gene, membro da família do domínio forkhead, responsável principalmente pelo desenvolvimento de ovários durante a determinação e diferenciação sexual de fêmeas. Os estudos evolutivos realizados ...
Experimental disturbances reveal group-level costs of social instability
In group-living species, social stability is an important trait associated with the evolution of complex behaviours such as cooperation. While the drivers of stability in small groups are relatively well studied, little ...
Relationship between physical and genetic distances along the zebra finch Z chromosome
(Springer, 2008-12)
Nine bacterial artificial chromosomes containing genes linked to the Z chromosome of the zebra finch (Taeniopygia guttata) were localized using FISH on synaptonemal complex spreads. Their positions were correlated with ...
Neural coding of sound envelope structure in songbirds
(Springer, 2017-12-12)
Songbirds are a well-established animal model to study the neural basis of learning, perception and production of complex vocalizations. In this system, telencephalic neurons in HVC present a state-dependent, highly selective ...
Evolução e organização genômica do gene FOXL2 em vertebrados
(Universidade Estadual Paulista (UNESP), 2014)
Adult zebra finches rehearse highly variable song patterns during sleep
(PeerJ Inc., 2017-02)
Brain activity during sleep is fairly ubiquitous and the best studied possible function is a role in memory consolidation, including motor memory. One suggested mechanism of how neural activity effects these benefits is ...
Intestinal α-glycosidase transcriptional responses during development and diet adjustment in altricial birds
(Company of Biologists, 2018-03)
We describe developmental changes in maltasic activity and its mRNA until adulthood, and in response to an increase in dietary starch. We studied house sparrows (Passer domesticus), which undergo a natural switch from ...
Syringeal EMGs and synthetic stimuli reveal a switch-like activation of the songbird’s vocal motor program
(National Academy of Sciences, 2018-08)
The coordination of complex vocal behaviors like human speech and oscine birdsong requires fine interactions between sensory and motor programs, the details of which are not completely understood. Here, we show that in ...
Molecular cloning and characterization of the germline-restricted chromosome sequence in the zebra finch
(Springer Verlag Berlín, 2009-05)
The zebra finch (Taeniopygia guttata) germline-restricted chromosome (GRC) is the largest chromosome and has a unique system of transmission in germ cells. In the male, the GRC exists as a single heterochromatic chromosome ...
Small intestinal epithelial permeability to water-soluble nutrients higher in passerine birds than in rodents
(Wiley Blackwell Publishing, Inc, 2018-12)
In the small intestine transcellular and paracellular pathways are implicated in water-soluble nutrient absorption. In small birds the paracellular pathway is quantitatively important while transcellular pathway is much ...
