Excretion Routes of Okadaic Acid and Dinophysistoxin-2 from Mussels (Mytilus galloprovincialis) and Cockles (Cerastoderma edule)

open access: yesToxins
The knowledge of the routes of excretion of the toxins accumulated by molluscs is a key step in designing methods that accelerate depuration. In this work, the excretion route, in mussels and cockles, of the main diarrhetic shellfish poisoning (DSP ...

Even a slight temperature increase triggers the inhibition of Symbiodiniaceae cell division and promotes cell expulsion in the coral Acropora selago

open access: yesPhycological Research, EarlyView.
SUMMARY Coral bleaching, characterized by the loss of Symbiodiniaceae symbionts from corals, is promoted both by acute high‐temperature events and by prolonged moderate thermal stress. However, the mechanisms responsible for decreases in Symbiodiniaceae cell densities within corals remain unclear. Symbiodiniaceae cells within corals proliferate through

Feasibility of restoring native oyster reefs in highly modified urban estuaries

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Urbanized estuaries are highly altered systems characterized by modified shorelines, degraded marine habitats, and abundant non‐native species. In South Australia's largest urbanized estuary, community‐based restoration initiatives aim to restore native flat oyster reefs (Ostrea angasi) lost over a century ago.

THE USE OF ALGAE CONCENTRATES, DRIED ALGAE AND ALGAL SUBSTITUTES TO FEED BIVALVES

open access: yesMakara Seri Sains, 2011
Microalgae have high nutritional value and are used to feed adult and larval stages of bivalves, the larvae of some fish and crustaceans and zooplankton. However, microalgae production for aquaculture animal is very expensive.

Bioturbating bivalves show potential to bioremediate degraded soft sediments by restoring ecosystem function

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Natural recovery of disturbed marine ecosystems can take years, mainly because long‐lived, functionally important species are lost. To regain ecosystem services, the focus of estuarine restoration is shifting from biodiversity metrics to functional restoration.

Microbial mats and thalassinid shrimp: Spatial and geochemical interactions in a modern intertidal environment

open access: yesSedimentology, EarlyView.
ABSTRACT This research examines the spatial and geochemical interactions between mat‐forming microorganisms and thalassinid shrimp in an intertidal flat situated on the shores of Willapa Bay, Washington, USA. The study serves as a contemporary analog for the relationships between mats and burrowing organisms in deep time.

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

open access: yesSedimentology, EarlyView.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

Spherulite in the modern aragonitic travertine stromatolite has a calcite core with exopolymers

open access: yesSedimentology, EarlyView.
ABSTRACT Spherulites are spherical to ellipsoidal particles formed by various crystalline substances and can be abiotically synthesised in the laboratory. Among various spherulite types, spherulites composed of calcium carbonate are also found in various natural environments, but their abiotic or biotic origins are still controversial.

Let's Get to the Bottom of the Arctic! [PDF]

open access: yes
In this lesson students investigate benthic communities in the deep Arctic Ocean to determine the factors that influence their compositions. As a result of this activity, students will be able to identify the three realms of the Arctic Ocean and describe
