Dental crown morphological variation and heterodonty in carcharhiniform sharks

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3432-3454, November 2026.
Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce. The order Carcharhiniformes, the most diverse among sharks, comprises 304 valid species that display remarkable ...

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3455-3466, November 2026.
Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Autonomous self‐pollination provides reproductive assurance, whereas insect pollination enhances yield in sesame under tropical field conditions

open access: yesAnnals of Applied Biology, Volume 189, Issue 3, November 2026.
This study demonstrates that Sesamum indicum L. combines autonomous self‐pollination and insect‐mediated pollination under tropical field conditions. Autonomous self‐pollination provides reproductive assurance, whereas insect pollination increases grain yield by 28.6%, corresponding to a pollinator dependence of 22%.
