Temporal tracking of mineralization and transcriptional developments of shell formation during the early life history of pearl oyster Pinctada maxima [PDF]

open access: yes, 2011
Molluscan larval ontogeny is a highly conserved process comprising three principal developmental stages. A characteristic unique to each of these stages is shell design, termed prodissoconch I, prodissoconch II and dissoconch.

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Genetic diversity of two Portuguese populations of the pullet carpet shell Venerupis senegalensis, based on RAPD markers: contribution to a sustainable restocking program [PDF]

open access: yes, 2014
The pullet carpet shell Venerupis senegalensis (=V. pullastra) is a commercially important species in Portugal, Spain, France, and Italy.

Mobile consumers influence the shoreward edge of intertidal seagrass ecosystems

open access: yesJournal of Animal Ecology, EarlyView.
Ecological paradigms suggest that the environmentally stressful edge of a habitat is determined by physical factors. The work finds that, counter to these paradigms, an environmentally stressful edge can also be impacted by biotic interactions and are more complex than suggested.

Biological performance of the penshell Atrina maura and mussel Mytella strigata under different water flow regimes

open access: yesCiencias Marinas, 2010
Three water flow rates (3.1, 7.3, and 12.1 cm s–1) were used during a 26-day period to determine their effects on shell dimensions, tissue mass, condition index, biochemical composition of tissues, and mortality of the penshell Atrina maura and mussel ...

Accumulation and elimination dynamics of the hydroxybenzoate saxitoxin analogues in mussels Mytilus galloprovincialis exposed to the toxic marine Dinoflagellate Gymnodinium catenatum [PDF]

open access: yes, 2018
Paralytic shellfish poisoning (PSP) is a severe food-borne illness, caused by the ingestion of seafood containing paralytic shellfish toxins (PST), which are naturally produced by marine dinoflagellates and accumulate in shellfish during algae blooms ...

Trematode infection buffers heat stress in blue mussels Mytilus edulis: The role of heat shock proteins

open access: yesJournal of Animal Ecology, EarlyView.
The study shows that parasite infection changes heat shock protein expression and can increase heat tolerance in blue mussels. By separating parasite and temperature effects, the results suggest that infection may improve survival during heat stress, highlighting important parasite–host interactions for climate change resilience. Abstract The influence

Morfometría de Sanguinolaria cruenta (Bivalvia: Psammobidae) en playa Tucacas, Falcón, Venezuela

open access: yesRevista de Biología Tropical, 2001
Se colectaron 312 conchas de S. cruenta con su ligamento en Playa Tucacas, Edo. Falcón, en mayo de 1999. A cada ejemplar se le midió: longitud antero-posterior, altura total, ancho, longitud anterior, altura dorsal, área de la valva y su peso.

Decoding Dual Regulatory Layers: Integrating Differential Expression and Alternative Splicing Dynamics in the Evolution of Laryngeal Echolocation Across Chiropteran Lineages

open access: yesIntegrative Zoology, EarlyView.
We integrated short‐read and long‐read RNA‐seq data from cochlear tissues of echolocating and non‐echolocating bats to disentangle transcriptional and post‐transcriptional regulation. Echolocating bats showed neural‐function enrichment among differentially expressed genes, while alternatively spliced genes were linked to epigenetic regulation. Overlaps

Effects of macrobenthos on sediment-water oxygen and ammonium fluxes. Final Report. [PDF]

open access: yes, 1997
Sediments are an important location in determining the fate of nutrients entering the estuary. Role of sediments needs to be incorporated into water quality models.
