Periodic gonadal activity and protracted mating in elasmobranch fishes
Temporal patterns of gonad development are determined by environmental cues that regulate hormonal cycles and ultimately affect a population's mating system. Annual periodicity of gonad histology isExpand

Arginine Vasotocin Neuronal Phenotypes among Congeneric Territorial and Shoaling Reef Butterflyfishes: Species, Sex and Reproductive Season Comparisons
Arginine vasotocin (AVT) and the homologous arginine vasopressin (AVP) neuropeptides are involved in the control of aggression, spacing behaviour and mating systems in vertebrates, but the functionExpand

Response properties and biological function of the skate electrosensory system during ontogeny
Abstract This study examined the response properties of skate electrosensory primary afferent neurons of pre-hatch embryo (8–11 weeks), post-hatch juvenile (1–8 months), and adult (>2 year) clearnoseExpand

Sensitivity and response dynamics of elasmobranch electrosensory primary afferent neurons to near threshold fields
Abstract Elasmobranch fishes localize weak electric sources at field intensities of <5 ηV cm−1, but the response dynamics of electrosensory primary afferent neurons to near threshold stimuli in situExpand

Sound production and spectral hearing sensitivity in the Hawaiian sergeant damselfish, Abudefduf abdominalis
SUMMARY Sounds provide important signals for inter- and intraspecific communication in fishes, but few studies examine fish acoustic behavior in the context of coevolution of sound production andExpand

Kinematic Analysis of Suction Feeding in the Nurse Shark, Ginglymostoma cirratum (Orectolobiformes, Ginglymostomatidae)
Abstract Inertial suction feeding is known to occur in some sharks, but the sequence and temporal kinematics of head and jaw movements have not been defined. We investigated the feeding kinematics ofExpand

Determinants of feeding territory size in the corallivorous butterflyfish, Chaetodon multicinctus
Abstract Both sexes of the monogamous coral-feeding butterflyfish, Chaetodon multicinctus , forage as energy maximizers, are constrained by the time available for feeding, and vigorously defend theirExpand

Acoustic behaviors in Hawaiian coral reef fish communities
Coral reef fish communities often include hundreds of sympatric species which are of great inter- est to reef conservation and fisheries managers. Long- term acoustic monitoring of fish sounds can beExpand

Morphology of the mechanosensory lateral line system in the Atlantic Stingray, Dasyatissabina: The mechanotactile hypothesis
The biological function of anatomical specializations in the mechanosensory lateral line of elasmobranch fishes is essentially unknown. The gross and histological features of the lateral line in theExpand
