Evidence of a marine larval stage in coastrange sculpin Cottus aleuticus from a small coastal stream in California, USA, based on otolith strontium isotopes

open access: yesJournal of Fish Biology, EarlyView.
Abstract Cottus aleuticus (coastrange sculpin) is one of two North American facultatively amphidromous sculpins, but habitat use during its planktonic larval stage is poorly documented. We analysed strontium isotopes (88Sr and 87Sr/86Sr) in otoliths of 10 adult C. aleuticus from a small coastal California stream.

Development of the abdominal musculature in the chicken embryo

open access: yesJournal of Anatomy, EarlyView.
In this study, we investigate anatomy, morphogenesis, segmental origin, and fiber formation of the abdominal musculature in the chicken embryo. We show that abdominal muscles arise from somites 24 to 28, and that the segmental identity of individual fibers in the abdominal muscle sheets is maintained.

The effect of early diagenetic processes on the quantification of fossil micrometeorite abundance and flux in the geological record

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Fossil micrometeorites (MMs) recovered from lithified sedimentary rocks, particularly iron‐rich (I‐type) cosmic spherules (CSs) provide valuable insights into past dust‐forming events. Their abundances, when combined with estimates of local sedimentation rates can be used to reconstruct the flux of extraterrestrial dust.
