Conservation and management efforts for white sharks (Carcharodon carcharias) remain hampered by a lack of basic demographic information including age and growth rates. Sharks are typically aged by counting growth bands sequentially deposited in their vertebrae, but the assumption of annual deposition of these band pairs requires testing. We compared radiocarbon (Δ(14)C) values in vertebrae fro...

The maturity, sex ratio, gonadosomatic index (GSI) and fecundity of Coryphaena hippurus was investigated from 347 specimens collected along Karnataka coast, south-eastern Arabian Sea August 2017 to May 2018. Overall ratio 1:3.5 (male:female) indicated dominance females in the fishery differed significantly (p<0.05) all months, except January, December. fork length (FL) at 50% maturity (Lm50)...

In this study, the morphology, anatomy, pollen morphology, leaf and seed micromorphology and karyology of the Turkish endangered endemic Physoptychis haussknechtii were investigated in detail for the fi rst time. The species was studied in terms of detailed morphology. Basal leaves are narrowly spatulate and cauline leaves are linear to oblanceolate; both leaves are covered with fl attened stal...

Antimonene -- a single layer of antimony atoms and its few forms are among the latest additions to 2D mono-elemental materials family. Numerous predictions experimental evidence remarkable properties including (opto)electronic, energetic or biomedical, others, together with robustness under ambient conditions, have attracted attention scientific community. However, electrical is still lacking. ...

Dr Shackcloth: And another question. Did you use anything fairly subjective looking at gastric dilatation? Did you try any radiological methods or looking at factors such as paracetamol absorption to give you a much better quantitative measure of gastric emptying? Dr Renaud: To measure the gastric distension? Dr Shackcloth: That is fairly subjective. You could use radioactive tracers or paracet...

Abstract Background Follicular lymphoma (FL) is the second most common adnexal lymphoma of the eye that almost all of them are reported in elderly patients. Primary FL of the eye has been reported in only two children. Pediatric FL appears to be biologically distinct from typical adult FL. In cases without other organ involvement excision alone with close monitoring is a treatment of choic...

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...

in this study, the effect of garlic extract on the growth performances ( body weight increase (bwi), specific growth rate (sgr), condition factor (cf), final length (fl) and weight (fw)), feed indices (feed conversion rate (fcr), protein efficiency ratio (per), protein production ratio (ppr)) and body composition (protein, fat, moisture and ash) of mugil cephalus larvae were studied in four tre...
