Summary: The cause of harmful algal blooms has been a mystery, but research using genetic technologies has made progress in understanding its mechanism. A long-term monitoring of toxic algae and its associated bacteria as a community, known as 'holobiont', in Chilean coastal waters has been conducted from the perspective of bacteria as the driver of algal blooms. This review discusses the challenges of holobiont monitoring, particularly in standardization and compliance with monitoring protocols, to ensure reliable and sustainable data collection. It suggests adopting the high-throughput sequencing (HTS) standard operating procedure (SOP) by the International Human Microbiome to enhance the quality and consistency of holobiont monitoring in the harmful algal world.

Summary: Harmful algal blooms (HABs) are increasing globally, and the relationship between HAB aerosols and human health remains unclear. This review synthesizes current knowledge and identifies gaps in understanding this relationship. Some HAB aerosols have been linked to respiratory outcomes, but direct measurements of aerosol or toxin concentrations are lacking, and epidemiological studies are limited. Further research is needed to explore the health effects of other HAB species, dose-response relationships, effects of concurrent exposures, the impact of long-term exposures, and disparities in vulnerable populations.

Summary: Species distribution models (SDMs) are commonly used to predict range shifts, but they may be unreliable under climate change scenarios. This study shows that incorporating the evolution of thermal traits into SDMs significantly alters projected ranges and improves the precision of forecasting range dynamics under climate change.

Summary: Research shows that people are attracted to prosocial mates and display prosocial behaviors towards those they find attractive, which includes engaging in pro-environmental behaviors. Through two experiments, it was demonstrated that participating in pro-environmental behaviors can increase one's desirability in the mating market, and that people display a motivation to engage in such behaviors in the presence of attractive, opposite sex targets.

Summary: This study investigates the anti-predator behavior of Icelandic threespine sticklebacks in low-visibility environments. The results show that fish have different reactions to different predator cues and are greatly influenced by lighting conditions. Fish from highland lakes react fastest to mechano-visual cues and exhibit the highest activity levels.

Summary: This study analyzed the temporal and spatial variability of harmful algal blooms (HABs) in coastal waters of Fujian. It found that the number and impact area of HABs varied significantly over different decades, with the highest occurrence in the 2000s. The proportion of HABs caused by dinoflagellates decreased, while the proportion caused by diatoms increased. In the 2010s, toxic HAB events caused by Karenia mikimotoi increased in frequency and spatial coverage along the central Fujian coast.

Summary: Chemicals have long been acknowledged to impact human and wildlife behavior. Recent technological advancements have highlighted the adverse effects of contaminants on organismal behavior and ecological outcomes. Concerns about the lack of consideration of behavior in regulatory ecotoxicology have led to the exclusion of many studies from chemical risk assessments. A workshop with international representatives has resulted in consensus perspectives and recommendations to improve the integration of basic and translational sciences with regulatory practices.

Summary: In this study, 1064 nm confocal Raman spectroscopy combined with multivariate statistical analysis techniques was used to measure the differences in cell viability of different phytoplankton species. The combination of near-infrared Raman spectroscopy and multivariate data analysis allowed for reliable monitoring of small spectral changes and identification of specific features that classify cells as viable or nonviable. Carotenoid bands at 1527 and 1158 cm(-1) showed the most significant differences upon cell death.

Summary: The study found that males who care for offspring exhibit stronger laterality, with this being reduced outside the breeding season. Males with experience in mating and parenting also show stronger laterality compared to those without such experience. Fitness-related behaviors related to reproduction, such as courtship, spawning, and parenting, play a significant role in influencing lateralization.

Summary: This study revealed the relative importance of male and female identity in male courtship behavior, as well as the increased male responsiveness to stimulus females as the breeding season progressed. Furthermore, the results suggest that invitation latency is a consistent courtship attribute in males that can be adjusted plastically according to perceived female quality and environmental conditions.

Summary: The Bohai Sea in China, an important mariculture region, has experienced harmful algal blooms (HABs) for several decades. A dataset spanning from 1952 to 2017 was compiled to investigate changes in HABs and their potential drivers. The frequency of HAB events in the Bohai Sea has increased over time but plateaued in the last decade, and shifts in HAB-forming species and their distribution were observed. These changes are influenced by climate change, eutrophication, and mariculture development. Future monitoring programs, adaptive management strategies, and predictive models are needed to address the issue.

Summary: The frequency of harmful algal blooms (HABs) in the Bohai Sea has increased over time but has plateaued in the last decade. The history of HABs in the area can be categorized into three periods based on their frequency, scale, and HAB-forming species. The seasonal window of HAB events has started earlier and lasted longer, and the main hotspot has shifted from Bohai Bay to coastal waters of Qinhuangdao.

Summary: Nest predation has a significant impact on reproductive success, leading to higher energy and physiological costs for parents who have to defend their offspring. The presence of nest predators can influence male reproductive decisions and behaviors, but in the case of the three-spined stickleback, they were able to effectively defend their brood against the egg predator without impacting egg survival rates. This study suggests that individuals can adjust their reproductive behaviors in response to the presence of nest predators across various contexts.

Summary: This study investigates the impact of temperature differences on the interaction between the cestode parasite Schistocephalus solidus and its host, the three-spined stickleback. The findings indicate that temperature is not associated with the host-parasite interaction but can influence host fitness regardless of infection. These results highlight the importance of considering natural settings when interpreting laboratory experiment findings and suggest potential consequences for host demography and parasite transmission dynamics.

Summary: The frequency and duration of heatwaves are increasing due to human activities. However, experimental studies often underestimate the effects of longer periods of higher temperature on species. This study shows that species with longer generation times may not be able to adapt to prolonged periods of extreme heat, resulting in reduced fitness.

Summary: Environmental disturbances can cause individuals to change their behavior, which in turn can impact ecosystem structure, biodiversity, stability, and services. Research should focus on species whose behavioral responses have a larger impact on ecosystems to better understand their interactions and consequences. By synthesizing theory and empirical evidence, we can develop a framework that links behavior responses to altered species interactions, community dynamics, and ecosystem processes.

Summary: To maximize survival, prey often integrate multiple anti-predator defenses. This study investigated how morphological and behavioral defenses interact and found that the presence of morphological defense enhances the use of behavioral defense. However, adding the behavioral defense does not improve survival. The rotifer, Brachionus calyciflorus, uses spines and floating behavior to defend itself, but only spines are needed to reduce predation risk.

Summary: Aquatic ecosystems are undergoing rapid changes due to human activities, which in turn affect the abundance and distribution of fishes and can have consequences for ecological structure and function. Behavioural responses, such as altered habitat choice or foraging activity, play a crucial role in these changes. However, there is a lack of knowledge regarding the consequences of these responses for populations, communities, and ecosystems. It is important to understand how and why behaviour is affected by human activities and how these behavioural responses influence higher ecological levels in order to determine the ultimate effects of human activities on aquatic ecosystems.

Summary: This study shows that the peak wavelength of artificial light has an impact on the mate attraction success of glow-worms. Short wavelengths, such as blue and white light, decrease the attraction effectiveness, while long wavelengths, such as yellow and red light, have a better attraction effect. Therefore, adjusting the spectrum of artificial light can effectively mitigate the negative effects of light pollution on glow-worm reproduction.

Summary: Colour polymorphisms are examples of intraspecific variation, and different coloured individuals may exhibit differences in behavior that are influenced by environmental factors. In a study on the red devil fish, it was found that environmental factors had color morph-specific effects on behavior, indicating that environmentally driven behavioral differences may be context dependent and play a role in maintaining color morph-specific behavioral strategies.

Summary: Global warming is altering terrestrial and aquatic ecosystems, affecting species interactions through indirect effects, especially trophic cascades. This study found that a common mesopredator, the threespine stickleback, altered the impact of warming on a Baltic Sea food web by increasing the consumption of herbivores and thus affecting the biomass transfer to higher trophic levels.
