New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.Harmful algal blooms caused by the paralytic shellfish toxin‐producing species Alexandrium pacificum have increased in recent years in one of the most important aquaculture regions of New Zealand, the Marlborough Sounds. Reoccurring blooms have created large cysts beds in the sediments throughout the sounds. In this region, large populations of the sea

The feeding ecology of some zooplankters that are important prey items of larval fish [PDF]
, 1984 Diets of 76 species of fish larvae from most oceans of the world were inventoried on the basis of information in 40 published studies. Although certaln geographlc, size- and taxon-specific patterns were apparent, certain zooplankton taxa appeared in the ...

Morphological and biomechanical adaptations of larval mandibles in Trichoptera (Insecta)
Physiological Entomology, Volume 51, Issue 1, Page 85-114, March 2026.Mandible morphology differs between predators and grazers: predators show pointed incisors, grazers sharp edges and setae. Mechanical properties depend on cuticle tanning, not elemental reinforcement. Functional mandible types reflect feeding strategies, with predators specialized for prey capture and grazers for scraping and collecting.

Mechanisms of near‐normal sea water dolomitisation: Mesohaline‐reflux or syn‐depositional?
The Depositional Record, Volume 12, Issue 1, February 2026.This study investigates the dolomitisation of the Eocene Dammam Formation on the Arabian Plate using petrographic, mineralogical, geochemical and isotopic analyses. The findings reveal two distinct dolomite types, formed primarily through normal‐to‐mesohaline sea water dolomitisation, challenging previous models such as sabkha‐meteoric mixing.
