A rare form of meningitis caused by Angiostrongylus cantonensis larvae was contracted in a Jamaican restaurant outbreak linked to contaminated romaine lettuce. The lettuce, imported from the US, was the likely source of the infection, which affected 12 individuals and hospitalized nine.
Researchers found that monarch larvae are more likely to be exposed to toxic corn pollen when pollen is shed during peak larval activity. In Ontario, 62% of larvae were exposed to toxic pollen, while in Iowa, the figure was 15%. The study suggests that agricultural habitats like cornfields are crucial for monarchs.
A recent study found that warmer water temperatures in Narragansett Bay result in 10-16% fewer winter flounder larvae surviving to the metamorphosis stage. The increase in temperature also affects the availability of food for higher-level organisms, leading to increased predation rates.
Researchers found that black swallowtail caterpillars fed on Bt corn pollen experienced significant growth rate reduction, varying up to three times smaller in distance from the crop. The discovery suggests sublethal effects of Bt corn pollen on non-target species and emphasizes the need for careful event selection by producers.
Scientists have detected early indications of a lobster decline in the Gulf of Maine, with juvenile lobsters showing a 40% decrease in Penobscot Bay. The research team's approach to monitoring three stages of lobster life suggests widespread declines at least west of Penobscot Bay.

This polyphenic study provides insight into the genetic processes that determine caste identity in honeybees.
The Fender's blue butterfly requires specific nectar and host plants to complete its reproductive cycle. A new study by University of California, Santa Barbara researcher Cheryl B. Schultz found that the species needs approximately 20 milligrams of wild flower nectar per square meter to support its population.
Researchers at San Francisco State University discovered that blister beetle larvae mimic female bees as part of a three-step strategy to infiltrate and parasitize the bee's nest. The larvae use cooperative behavior to lure male bees into pseudocopulation, which then transport them to multiple females.
The tortoise beetle uses its own feces to create a shield that deters most predators, but one predator, the carabid beetle, can penetrate it. The larvae attach fecal strands to their bodies and repair them if damaged, creating an almost impenetrable defense mechanism.
A groundbreaking study published in Nature reveals that many coral reef fish spend their life cycle close to home, rather than drifting in the open ocean. This finding has significant implications for marine conservation and fisheries management, as it challenges the prevailing view of larval dispersal.
Researchers found that desert bee larvae wait for rain to emerge, using a bet-hedging strategy to minimize losses in drought years. The approach allows them to thrive in arid environments.
Researchers propose hormonal function change led to unique larval stage innovation, allowing population explosion among insect groups. Insects with complete metamorphosis have diverse habitats and food sources due to the lack of competition between juveniles and adults.
A recent study found that mosquito fish preferentially eat tadpoles over mosquito larvae, leading to the decline of various frog and newt species. This ecological disaster may be linked to the widespread introduction of these fish as a form of biological control in the early 20th century.
Researchers find mosquitofish devour tadpoles just as readily as mosquitoes, decimating native amphibian populations in streams. The study urges local governments to reconsider using mosquitofish as a control measure.
