Summary: Functional responses are influenced by temperature and the size of prey and predator. This study found that predation rates increased with warming and predator age. Smaller prey were more likely to be preyed upon. These findings have implications for effective biocontrol strategies.

Summary: This study investigated the impact of vessel noise on blue mussels and planktonic species. The results showed that vessel noise does not affect the growth and feeding behavior of mussels and copepods, but it does reduce the egg production and size of rotifers.

Summary: The purpose of this study was to determine if the blue mussel Mytilus edulis can maintain constant ingestion rates by changing feeding rates in response to fluctuations in natural diets. The results showed significant individual variability in pumping rates and no correlation between pumping rate and food availability. However, population-level ingestion rates increased with increasing food availability.

Summary: The study found that blue mussels and clubbed tunicates can effectively utilize carbon from Picophytoplankton (PPP) in nutrient-rich marine ecosystems. They assimilate PPP carbon by ingesting PPP cells from water and recycling it through pseudofeces and feces, providing an ecological service in removing excess PPP in aquaculture settings.

Summary: Many generalist predators have flexible and rapid behavior to switch between prey species based on changing prey abundances. However, the mechanistic understanding of the relationship between individual behavior and feeding rates is poorly understood. In this study, three mechanistic models were developed to derive the relationship between observed individual behavior and feeding rates, providing novel functional responses for predators with prey switching and exclusive feeding. These functional responses conform to the Holling type III response and can be used to predict predators' diet compositions.

Summary: This study utilized flow cytometry to investigate short-term variations in the abundance of picophytoplankton in coastal regions of northeastern Taiwan. The research found that growth rates of picophytoplankton were higher during daytime than during 24-hour incubation periods, suggesting that estimates based on 24-hour sampling may not accurately reflect the true growth rates of these populations.

Summary: The effects of azamethiphos concentration and temperature on the physiology and survival of Chilean oysters were examined. Higher temperatures and lower pesticide concentration resulted in higher clearance rates and oxygen consumption rates. However, the survival rates were lower when exposed to higher pesticide concentration, regardless of the temperature. The interaction between temperature and pesticide had detrimental effects on the physiological performance and survival of O. chilensis.

Summary: Microplastics pose a serious threat to the marine environment, impacting ecosystem functioning and biodiversity. While there is a vast literature on the uptake of microplastics in different trophic levels, there is limited knowledge on potential strategies to mitigate microplastic pollution. Bioremediation, specifically focusing on three species (Sabella spallanzanii, Mytilus galloprovincialis, Phallusia mammillata), has shown promise in effectively removing microplastics.

Summary: The dynamic changes in plasma Epstein-Barr virus (pEBV) DNA after radiotherapy have a significant impact on the survival of nasopharyngeal cancer patients, with clearing pEBV DNA associated with improved survival. Post-radiotherapy pEBV DNA clearance may serve as an early surrogate endpoint for long-term survival in NPC.

Summary: Bivalve species showed varying clearance rates when exposed to different concentrations of isotopically labeled A. lagunensis cells, with the highest clearance rates at lower cell concentrations. Despite decreasing clearance rates with increasing bloom concentrations, bivalves were still able to consume algal cells at all levels and assimilate more cells at higher concentrations, highlighting the importance of healthy and diverse filter feeding communities in estuaries to combat harmful algal blooms.

Summary: This study aimed to evaluate and compare the feeding responses of two bivalve species, the non-native dark false mussel and the native scorched mussel, to different concentrations of suspended particulate matter. The non-native mussel showed higher clearance and ingestion rates at higher concentration levels, while the native mussel was more efficient at lower concentration levels. These results suggest that there may not be food competition between the two species.

Summary: This study combines microplastic data and foraging measurements on whales to quantify plastic ingestion rates and exposure risk in filter-feeding megafauna. Baleen whales predominantly feed at depths coinciding with high microplastic concentrations, with almost all microplastic ingestion occurring through trophic transfer. Fish-feeding whales are less exposed to microplastic ingestion compared to krill-feeding whales.

Summary: The seasonal variations in the picophytoplankton community structure were studied in the coastal ecosystem of the subtropical western Pacific. The dominant species, Synechococcus spp., showed a density ranging from 0.05 to 5.6 x 10(4) cells mL(-1) during the study period, with its maximum abundance in July 2020. Picoeukaryotes were less abundant, with a density ranging from 0.2 to 13.6 x 10(3) cells mL(-1), and their highest abundance was recorded in January 2020. The growth rates of Synechococcus spp. and picoeukaryotes varied throughout the study period, with picoeukaryotes showing a significantly higher growth rate.
