چکیده
software tool that bins genomic fragments that have first undergone limited preassembly into contigs. Their strategy uses a variational Bayesian approach combining sequence composition and correlated abundance across multiple samples to produce sequence assignments. CONCOCT bins genomes with high precision and recall in simulated and real data, providing higher coverage than can typically be reached by single-cell sequencing. Brief Communication p1144

Differential responsiveness in brain and behavior to sexually dimorphic long calls in male and female zebra finches.
In zebra finches (Taeniopygia guttata), as in most other songbird species, there are robust sex differences in brain morphology and vocal behavior. First, male zebra finches have larger song system nuclei--involved in sensorimotor learning and production of song--than females. Second, male zebra finches learn their song from a tutor, whereas female zebra finches develop a learned preference for...
متن کاملZebra Finches As a Model Species to Understand the Roots of Rhythm
VOCAL TIMING IN ZEBRA FINCHES Zebra finches are a widely used model species for neurobehavioral research, in particular in relation to song development and auditory processing. Males learn their songs from a tutor. Females don't sing, but do develop learned song preferences. Regardless of the differences, both sexes exchange calls in social interactions. Two fascinating recent studies looked at...
متن کاملBreeding Experience, Alternative Reproductive Strategies and Reproductive Success in a Captive Colony of Zebra Finches (Taeniopygia guttata)
Birds exhibit a remarkable diversity of different reproductive strategies both between and within species. Species such as the zebra finch (Taeniopygia guttata) may evolve the flexible use of alternative reproductive strategies, as well as benefit from prior breeding experience, which allows them to adaptively respond to unpredictable environments. In birds, the flexible use of alternative repr...
متن کاملZebra finches are sensitive to prosodic features of human speech.
Variation in pitch, amplitude and rhythm adds crucial paralinguistic information to human speech. Such prosodic cues can reveal information about the meaning or emphasis of a sentence or the emotional state of the speaker. To examine the hypothesis that sensitivity to prosodic cues is language independent and not human specific, we tested prosody perception in a controlled experiment with zebra...
متن کاملSexual dimorphism of auditory activity in the zebra finch song system.
While the tracheosyringeal motor neurons of anesthetized male zebra finches fire in response to acoustic stimuli, the same motor neurons in females show no such response. Females masculinized by estradiol implants on Days 1 or 2 after hatching may develop auditory responses in their tracheosyringeal motor neurons; the presence of the response is directly related to the degree of masculinization...
