Adaptive Reproductive Strategies of Limpets in a Harvest‐Influenced Environment
Fisheries Oceanography, EarlyView.ABSTRACT Limpet harvesting is a size‐selective activity that primarily removes the largest individuals, leading to reduced reproductive output. This study investigates the fecundity strategies of two limpet species, Patella aspera and Patella crenata, inhabiting the rocky shores of Gran Canaria.

Geostandards and Geoanalytical Research, EarlyView.Key Points High‐precision measurement results for δ13C in basaltic glasses were achieved down to 25 μg g‐1 CO2 using a refined measurement procedure via large‐geometry SIMS. Three new hydrous basaltic glasses (ETNA24, ETNA32, ETNA36) were established as reference materials.
