- The quantity–quality trade-off: differential effects of daily food availability times on reproductive performance and offspring quality in diurnal zebra finches
Summary: Absence of food in the morning compromises reproductive fecundity but not quality of offspring, whereas food absence in the evening compromises quality (skeletal growth and overall size) of offspring but not reproductive fecundity in continuously breeding diurnal zebra finches.
- Multiple optic gland signaling pathways implicated in octopus maternal behaviors and death
Editors' Choice: Octopus optic glands employ a multiplex progression of signaling molecules to regulate maternal behaviors.
- Hormonally mediated effects of artificial light at night on behavior and fitness: linking endocrine mechanisms with function
Summary: We review key findings on how artificial light at night affects major endocrine axes and suggest future studies that might ameliorate negative effects.
- Non-adrenergic control of lipolysis and thermogenesis in adipose tissues
Summary: In this Review, we discuss adrenergic and non-adrenergic mechanisms controlling lipolysis and thermogenesis in adipocytes and provide a comprehensive overview of pro- and anti-lipolytic mediators.
- Genetic editing of the androgen receptor contributes to impaired male courtship behavior in zebrafish
Summary: Modification of a gene implicated in male reproductive behavior using genetic editing tools results in the impairment of courtship behavior in a vertebrate model.
- Effects of estradiol on neural responses to social signals in female túngara frogs
Summary: Estradiol changes the basal activity of the auditory midbrain and limbic forebrain of female túngara frogs, and modifies the response of the preoptic area to mating calls.
