Summary: The study indicates that toxic cyanobacteria have different effects on adaptive predator-induced responses in zooplankton, affecting growth and reproduction under the interaction of high-quality diets and predator cues. Resource allocation to antipredator morphological defense remains unchanged, but somatic growth and reproduction are affected by toxic cyanobacteria in zooplankton.

Summary: The study found that in response to predator fed cyanobacterium, the quantum yield of photosystem II increased in most algal and cyanobacterial species studied, while the yield did not change significantly in response to predator fed alga in most of these species. Additionally, cyanobacteria tended not to respond to a non-feeding predator.

Summary: The study revealed that gut microbiome composition of Daphnia pulex is highly correlated with the organism's response to multiple stressors. Predation risk and copper contamination interact to influence traits through digestive physiology. Antibiotic manipulation of the microbiome can reverse trait responses across life history, morphology, and body condition.

Summary: Species that are not closely related can exhibit similar inducible traits, but the molecular mechanisms underlying these responses and whether they are shared between species are often unknown. In this study, two Daphnia species from different subgenera were compared, and they showed similar induced morphological changes when exposed to the same predation threat. The response to predation risk resulted in the same direction of changes in expression levels of 23 orthologues involved in various biological processes, suggesting the conservation of genes responding to predation pressure in Daphnia for millions of years.

Summary: This study examines the associations between abundance, depth distribution, temperature and predation pressure of the copepod Calanus finmarchicus. It finds that predation pressure and temperature can influence the seasonal and vertical distribution of these zooplankton.

Summary: Nitrogenous pollutants from human activities pose direct and indirect risks on aquatic organisms and interspecific relations. The effects of these pollutants on induced defense and nitrite tolerance in Daphnia pulex were investigated. Results showed that increasing nitrite reduced Daphnia survival and reproductive capacity, and early nitrite exposure interfered with spine elongation. Nitrite concentrations had no effect on relative spine length. Biomarker analyses indicated greater impairment in reproductive capacity than morphology and survival. Predation risk reduced Daphnia's nitrite tolerance. Overall, these findings highlight the exacerbation of predator-induced miniaturization and reduced nitrite tolerance in zooplankton exposed to long-term nitrite pollution.

Summary: This study systematically reviewed the use of melatonin in the management of periodontitis, finding that melatonin supplementation improved periodontal parameters but with a high risk of bias in the included studies.

Summary: Predators selectively prey on infected hosts, possibly because infection changes the visibility of prey. Using a mathematical model and hypothesis, the study found that various parasites can darken Daphnia infected by them, making them more visible to predators. This supports the idea that selective predation by fish on infected Daphnia could result from the effects of infection on Daphnia's visibility.

Summary: This study used a species distribution model framework combined with machine learning algorithms to describe the spatial distribution of two freshwater zooplankton species in northern Italy. The results showed that machine learning algorithms outperformed other models, and temperature seasonality and precipitation in the warmest quarter were found to be the most important variables influencing species distribution. The simulation suggested that both species would shift their distribution towards lower latitudes in response to future climate change.

Summary: This study investigates the presence, biosynthetic pathway, and rhythms of melatonin in bivalves, focusing on the razor clam Sinonovacula constricta. The results show that melatonin plays a role in light signal transduction and the circadian system in this bivalve species.

Summary: Analyzing the genomic diversity variation in a species can provide valuable insights into its historical demography, biogeography, population structure, ecology, and evolution. This study focuses on the genomic variation of the microsporidia parasite Hamiltosporidium, which infects the freshwater crustacean Daphnia magna. The study investigates the factors contributing to nucleotide variation, including the mode of reproduction, transmission, and geography. The results demonstrate two main parasite lineages and a pattern of isolation-by-distance, suggesting recent parasite spread through host populations and the loss of sexual reproduction.

Summary: Prey organisms, such as Daphnia in freshwater ecosystems, exhibit phenotypic plasticity in defensive traits in response to variable and unpredictable predation risks, developing inducible morphological defenses to reduce susceptibility to predators.

Summary: Assessing the extent of permafrost is crucial for understanding the impact of climate change on Arctic ecosystems. This study proposes a new method that combines temperature and electrical resistivity measurements to estimate the distribution of permafrost. The results show that certain vegetation and slope characteristics are associated with warmer and smaller permafrost bodies, as well as a higher occurrence of taliks.

Summary: The cellular mechanisms underlying morphological defense expression in Daphnia, particularly the development of defensive crests, have been investigated. The study found that cell division is delayed in favor of cell growth, leading to crest formation. The defense development starts in the ventral region and extends towards the cranial and dorsal directions. These cellular changes begin as early as 2 hours after predator exposure.

Summary: This study provides a detailed analysis of the rhythmic expression of key components of the biological clock in common carp. The expression of clock genes, bmal genes, per genes, and cry genes in the brain, pituitary gland, and retina of carp was found to be the highest. The expression pattern of clock and bmal genes aligned with the lights off, while per genes showed a similar phasing with acrophase close to light onset. The expression of cry genes varied depending on the type of tissue and gene subtype.

Summary: The contamination of freshwater environments by pharmaceuticals, such as fluoxetine, can disrupt the predation behavior of fish and the growth of their prey, water fleas. This study found that exposure to environmentally relevant concentrations of fluoxetine resulted in larger water fleas but altered hunting behavior in fish, with shorter reaction distance and slower feeding rate. These effects occurred regardless of water flea size and treatment regime.
