Age Structure, Sexual Dimorphism, and Ontogenetic Melanism in a Captive Population of the Endangered Freshwater Turtle Mauremys reevesii (Gray 1831)

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Effectively illustrates the sexual size dimorphism in males and females of endangered Mauremys reevesii. ABSTRACT The age structure of animal populations plays a pivotal role in understanding their demographic dynamics and reproductive potential. Although carapace growth ring analysis is widely used to estimate turtle ages, environmental variability ...

Unusual development of an accessory otolith in herring (Clupea harengus) larva

open access: yesFisheries & Aquatic Life
Otoliths are key to reconstructing fish life history, as their structure records individual and environmental information. These inner ear structures grow incrementally, revealing growth rates, migration patterns, and environmental conditions.

Congenital CMV and Hearing Loss—How Does it Happen and How to Prevent it

open access: yesReviews in Medical Virology, Volume 36, Issue 3, May 2026.
ABSTRACT Congenital cytomegalovirus (cCMV) is found worldwide and significantly contributes to permanent childhood hearing loss. CMV has been known to cause sensorineural hearing loss (SNHL) for more than half a century, and CMV‐related hearing loss has consistently been present in all childhood populations where infants with cCMV have been identified ...

Integrating Sr isotopes, microchemistry, and genetics to reconstruct Salmonidae species and life history

open access: yesArchaeometry, Volume 68, Issue S2, Page S104-S129, May 2026.
Abstract Recent approaches to fisheries research emphasize the importance of the coproduction of knowledge in building resilient and culturally mindful fisheries management frameworks. Despite widespread recognition of the need for Indigenous knowledge and historical reference points as baseline data, archaeological data are rarely included in ...

Age and growth of swordfish (Xiphias gladius) caught by the Hawaii-based pelagic longline fishery [PDF]

open access: yes, 2007
We verified the age and growth of swordfish (Xiphias gla-dius) by comparing ages determined from annuli in fin ray sections with daily growth increments in otoliths.

Traditional and Geometric Morphometrics and Invariant Shape Descriptors of Catfish Otoliths in the Yucatán Peninsula: Tools for Species Identification and Individual Size Estimation at Maya Archaeological Sites

open access: yesArchaeometry, Volume 68, Issue S2, Page S88-S103, May 2026.
ABSTRACT This study investigates the use of otolith shape analysis for species identification and size estimation in Ariopsis felis and Bagre marinus, based on 181 modern otoliths obtained from a scientific collection and recent sampling in the coastal regions of Campeche and Yucatán, as well as 39 archaeological otoliths corresponding to the Early ...
