Researchers found that small oyster shell reefs are effective in slowing erosion on low wave energy shorelines, but less effective in higher wave energy environments. This study suggests that oyster reefs could be a useful tool for coastal managers to stabilize shorelines under low energy conditions.
A 425-million-year-old clam-like creature, known as an articulate brachiopod, has been found with its soft parts still intact. The fossil provides a unique insight into the workings of ancient shellfish and challenges existing assumptions about their anatomy.
Rising temperatures exacerbate cadmium's toxic effects on oysters, reducing their survival chances and increasing metabolic rate. As a result, future research will focus on the thermal tolerance of cold-blooded species affected by cadmium pollution.
A study by Virginia Tech researchers found that high hydrostatic pressure can effectively inactivate the Hepatitis A virus in oysters, reducing the risk of foodborne illness. This breakthrough has significant implications for oyster processing and distribution, as well as consumer safety.
Researchers investigated Vibrio interactions with the bivalve immune system, identifying factors that influence vibrios' fate within the host. Different Vibrio species and strains adopt a common strategy to undermine host cell functions, disregulating signaling pathways.
A team of scientists found that a small mutation in softshell clams' nerve tissue prevents paralytic shellfish toxins from binding, causing the clams to accumulate high levels of toxins. This resistance allows them to survive harmful algal blooms and increase the risk of paralytic shellfish poisoning in humans.
A mutation in clams has been discovered that protects them against paralytic shellfish poisoning, but increases the risk to humans who consume them. The mutation enables contaminated clams to survive in areas with toxic algae, highlighting a need for new safety protocols.
Eating seafood containing toxic substances like tetrodotoxin and ciguatera can cause severe neurological effects. Shellfish poisoning is a common type of food-borne illness affecting the USA with symptoms including numbness, slurred speech, and paralysis. Prevention is key to avoiding life-threatening poisoning.
A new study by Kidwell found that patterns in the fossil record of marine bivalves are not dictated by differences in shell toughness. The study suggests that variations in shell composition may even favor organisms with less durable shells, adding to our understanding of evolutionary history.
A scientist at the Marine Biological Laboratory has published a study showing that a combination of pollutants bromoform, chloroform, and tetrachloroethylene can alter nerve cell growth in clam embryos. The study found increased production of an enzyme involved in neural development, which may be linked to neurological disorders such a...
Research shows how individual species interact with each other after extinction, affecting recovery and evolution. Marine snails' feeding behavior changed from drilling holes to reach soft bodies inside clam shells.
An international team of scientists has successfully sequenced the entire clam genome, providing crucial insights into the organism's active DNA. This breakthrough information will enable researchers to create antibodies for studying cellular processes involved in various diseases.
The study reveals that oysters' immune blood cells contain rhombohedral-shaped crystals used to form shell. The research aims to understand biomineralization for potential breakthroughs in medical and material sciences.
A team of Virginia Tech researchers is assessing the reliability of measuring photos of fossils to compile body size data. They found that while the method has some bias, it can still be useful in answering important questions about the history of life.
A study published in Nature reveals that a certain clam species can elongate its foot up to 30 times the length of its shell to access necessary chemicals. The clams, which live in symbiotic relationships with marine bacteria, use their extended feet to burrow extensive mines into sediment.
Researchers at the University of Florida have developed a novel approach to curing mice of Vibrio vulnificus, a deadly bacteria that causes flu-like symptoms and can be fatal. The treatment involves using a virus to attack the bacterial source, showing promise as an alternative to antibiotics for treating this disease.
A study by Jennifer Stempien explores the geographic influences on species variation in ancient bivalves. She found that specimens from different locations exhibited wide variability in physical characteristics, suggesting a strong geographic influence over time.
A recent study on Brazilian brachiopods has provided valuable insights into the life and times of ancient creatures. The research, led by David Rodland, sheds light on the encrustation patterns of modern brachiopods and their potential to estimate water depth and plankton productivity in ancient oceans.
The presentation highlights various sources of food poisoning, including animal, plant, and chemical contaminants, as well as common types such as bacterial, viral, and parasitic infections. Early identification of these organisms is crucial for preventing severe illness or death.
A recent study finds that decades-long declines in marine life populations are linked to centuries-old overfishing practices. Overfishing has caused significant ecological damage, including the loss of underwater kelp forests and seagrass beds, which have cascading effects on entire ecosystems.
Researchers used satellite images, fossils, and radiocarbon dating to estimate the prehistoric productivity of the Colorado River Delta. The study found that shellfish production declined by 20-fold due to human diversion of the river's flow.
A shellfish toxin study has discovered a mechanism that may help treat cystic fibrosis by stimulating fluid flow through protein phosphatase inhibition. This could lead to loosening of accumulated mucus in the lungs and gut, reducing bacterial infections and early death.
The institution has trained nearly 300 fishermen and helped them establish businesses in hard clam aquaculture. Graduates receive state-owned land leases, equipment, and seed to support their operations.
A University of Florida scientist has discovered that ancient oysters grew faster over time, revealing a key mechanism in the evolution of larger animal species. This finding challenges the long-held assumption that gradual growth drove evolutionary changes.
