Abstract: Avian pairs that defend resources year-round may demonstrate similar territorial behavior. We examined male and female responses of northern cardinal pairs to male simulated territorial intrusions. Pair members demonstrated comparable responses towards a male ‘intruder’,… read more here.

DOI: 10.1016/j.celrep.2020.03.081
Abstract: Despite being innate, displays of aggression are influenced by cortical activities. Here, using Vglut1 as a marker for inputs from cortical structures, we identify a small population of excitatory neurons located in the posterior amygdala… read more here.

DOI: 10.1016/j.yhbeh.2017.11.010
Abstract: ABSTRACT Urban songbirds of several species more vigorously defend their territories in response to conspecific song playback than do their rural counterparts, but the hormonal basis of this behavioral difference is unclear. It is well… read more here.

DOI: 10.1016/j.yhbeh.2021.104995
Abstract: Our understanding of the proximate and ultimate mechanisms shaping competitive reproductive phenotypes primarily stems from research on male-male competition for mates, even though competition is widespread in both sexes. We evaluate the hypothesis that the… read more here.

DOI: 10.1038/s41467-019-12212-7
Abstract: Motherhood is characterized by dramatic changes in brain and behavior, but less is known about fatherhood. Here we report that male sticklebacks—a small fish in which fathers provide care—experience dramatic changes in neurogenomic state as… read more here.
