Seasonal dynamics of dental sexual dimorphism in the Atlantic stingray Dasyatis sabina
Cartilaginous fishes continuously replace their teeth throughout their life (polyphyodonty) and often show a sexually dimorphic dentition that was previously thought to be an invariant sex character. Radial vector analysis of tooth shape in the polyphyodontic stingray Dasyatis sabina across a consecutive 24 month period shows a stable molariform morphology for females but a periodic shift in ma...
متن کاملElectroreception in the euryhaline stingray, Dasyatis sabina.
This study quantified the electrosensitivity of a euryhaline elasmobranch, the Atlantic stingray (Dasyatis sabina) across a range of salinities. Specimens from a permanent freshwater (FW) population in the St Johns River system, FL, USA, were compared with stingrays from the tidally dynamic Indian River Lagoon in east Florida, USA. Behavioral responses of stingrays to prey-simulating electric s...
متن کاملA Golgi study on the neuronal organization of the habenular ganglion in the red stingray, Dasyatis akajei.
The neuronal organization of the habenular ganglion (HG) was studied in the red stingray using the rapid Golgi method. The HG was made up of the medial (MH) and lateral habenular nucleus (LH), and the former nucleus was further divided into a dorsal, intermediate and ventral subnucleus. Only one type of neurons were observed in the MH, while the LH was composed of two types of neurons. In the l...
متن کاملCloning of two members of the calcitonin-family receptors from stingray, Dasyatis akajei: possible physiological roles of the calcitonin family in osmoregulation.
In cartilaginous fish, two cDNAs encoding calcitonin-family receptors were isolated for the first time from the stingray brain. The open reading frame of one receptor cDNA coded a 525-amino acid protein. The amino acid identity of this receptor to human calcitonin-receptor-like receptor (CRLR) is 64.5%, frog CRLR is 64.7%, and flounder CRLR is 61.2% and this was higher than to human calcitonin ...
متن کاملPatterns of Dental Sexual Dimorphism in Krapina
Sexual dimorphism is an important component of morphological variation and has been associated with a range of socioecological and cultural variables. Comparing patterns of dental sexual dimorphism in two Central European samples, Krapina and Pr fedmostí, may shed light on sexual differences in biocultural adaptation. However, studying sexual dimorphism in ancient populations needs to address m...
