Effect of type of otolith and preparation technique on age estimation of larval and juvenile spot (Leiostomus xanthurus) [PDF]

open access: yes, 2005
Otoliths of larval and juvenile fish provide a record of age, size, growth, and development (Campana and Neilson, 1985; Thorrold and Hare, 2002). However, determining the time of first increment formation in otoliths (Campana, 2001) and assessing the ...

Ensembles of wrappers for automated feature selection in fish age classification [PDF]

open access: yes, 2017
In feature selection, the most important features must be chosen so as to decrease the number thereof while retaining their discriminatory information. Within this context, a novel feature selection method based on an ensemble of wrappers is proposed and

Integrating Aegean Last Interglacial faunas into the Mediterranean palaeobiogeographic framework: New evidence from Karpathos (Greece)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Last Interglacial (LIG) or Marine Isotope Stage (MIS) 5e, spanning 129 to 116 kyrs ago, is recognised as one of the warmest periods in the Quaternary, with global sea surface temperatures (SSTs) 1°C–2°C higher than today, sea levels 5–10 m above the current level and biogeographical range expansion of specific tropical species into the ...

Vestibular Evoked Myogenic Potentials to Diagnose Vestibular Neuritis: A Scoping Review

open access: yesThe Laryngoscope, EarlyView.
Standardization of stimulation and recording protocols is essential to improve comparability across VEMP studies. Integrating cervical and ocular VEMPs with other vestibular tests enhances diagnostic accuracy and supports precise localization of vestibular neuritis.

Otolith morphometry and its role in determining the growth of Periophthalmus chrysospilos distributed in some coastal provinces in the Mekong Delta

open access: yesVeterinary Integrative Sciences
This article first provided information on otolith shapes, the variation of otolith weight by sex, fish size, season, and sampling site, and the linear relationship between otolith weight and fish size. A total of 815 Periophthalmus chrysospilos

Observational study on risk factors determining residual dizziness after successful benign paroxysmal positional vertigo treatment: The role of subclinical BPPV [PDF]

open access: yes, 2019
After successful treatment for benign paroxysmal positional vertigo, many patients may complain of residual dizziness. Possible explanations may be the persistence of otolith into canal insufficient to provoke noticeable nystagmus, utricular dysfunction ...
