Scotopic spectral sensitivity of the optomotor response in the green treefrog Hyla cinerea.
Amphibians are unusual among vertebrates in having two spectral classes of rod photoreceptors, unique amphibian "green" rods and typical vertebrate "red" rods. Although amphibians have been the subject of extensive research on visual function, it is not known whether possession of two classes of rods is a general feature of Amphibia, nor is it clear to what behaviors each class of rods contribu...
متن کاملSocial context influences androgenic effects on calling in the green treefrog (Hyla cinerea).
Courtship behavior in frogs is an ideal model for investigating the relationships among social experience, gonadal steroids, and behavior. Reception of mating calls causes an increase in androgen levels in listening males, and calling, in turn, depends on the presence of androgens. However, previous studies found that androgen replacement does not always restore calling to intact levels, and th...
متن کاملCorticosterone and Growth in Pacific Treefrog (Hyla regilla) Tadpoles
In all vertebrates, responses to environmental perturbation are regulated to at least some degree by glucocorticoid hormones (GCs). In amphibians, GCs, along with several other hormones, also play an important role in larval growth and development preceding metamorphosis. Given these two well-established functions, GCs might be expected to have a role in the well-documented effects that environ...
متن کاملSex-specific modulation of cell proliferation by socially relevant stimuli in the adult green treefrog brain (Hyla cinerea).
Social experience plays an important role in regulating the neural, physiological and hormonal changes that accompany the expression of reproductive behavior in vertebrates. This suite of functions is sexually dimorphic, with different neural control areas preeminent in males and females. In anuran amphibians, social experience comes in the form of acoustic communication, which is central to th...
متن کاملField and Laboratory Studies of the Susceptibility of the Green Treefrog (Hyla cinerea) to Batrachochytrium dendrobatidis Infection
Amphibians worldwide are experiencing devastating declines, some of which are due to the amphibian chytrid fungus (Batrachochytrium dendrobatidis, Bd). Populations in the southeastern United States, however, have not been noticeably affected by the pathogen. The green treefrog (Hyla cinerea) is abundant and widespread in the southeastern United States, but has not been documented to harbor Bd i...
