Summary: Since the 19th century, scientists have tried to quantify species distributions using techniques such as direct counting and microscopes. Automatic image processing and classification methods are now being utilized to avoid manual procedures for classifying marine plankton. This article summarizes the techniques proposed for classifying marine plankton from the beginning of this field to the present day, focusing on automatic methods that utilize image processing.

Summary: Predicting dispersal and quantifying ecological connectivity is crucial for understanding biodiversity. In this study, we used a hydrodynamic model combined with a particle tracker to examine the influence of different larval behaviors and hydrodynamic changes on dispersal predictions. Our results demonstrate the significant impact of vertical migration behavior on dispersal distance, especially for species with longer planktonic durations.

Summary: We have compiled the stratigraphic ranges of various taxa of carbonate producers in the Cretaceous period and summarized their ecological and physiological controls on calcification and carbonate production. The observed diversity patterns are compared with proxy data of Cretaceous climate and seawater chemistry to elucidate the effect of environmental change on carbonate production and sedimentation. Two characteristic patterns are recognized: the diversity of certain taxa trace the evolution of Cretaceous sea level, while the diversity of other taxa show significant reductions at the level of oceanic anoxic events (OAEs). Our findings highlight the vulnerability of benthic carbonate producers to environmental changes and the importance of high sea level and high temperatures in controlling diversity in certain taxa. Aragonitic or aragonite-dominated carbonate producers are most affected during extinction events related to OAEs, and there is a trend of decreasing aragonite dominance throughout the Cretaceous.

Summary: Prey animals use color and patterning to either avoid detection or advertise their unpalatability. This study examines how pattern use varies across phylogenetically related cryptic and aposematic butterfly larvae with different social behavior. The results show that longitudinal stripes are more common in cryptic larvae, while patterns associated with crypsis are more likely to be used by solitary larvae. Aposematic larvae, on the other hand, are more likely to display horizontal bands and spots. This research advances our understanding of pattern variation, coloration, and social behavior in lepidopteran larvae.

Summary: The study found that ocean acidification and ultraviolet radiation mainly exhibit additive stressor interactions on marine primary producers. Different sizes of algae show variations in interaction type frequencies, while the effects of high UVR on OA are amplified or mitigated depending on the duration.

Summary: The study demonstrates that sulfonamides can adsorb to plankton in the marine environment, with sulfamethazine being more readily adsorbed than sulfamethoxazole. The adsorption occurs quickly and the concentration on the plankton remains stable for a certain period, suggesting that marine plankton may retain sulfonamides at low levels per cell or individual.

Summary: Dispersal has significant implications for sessile organisms. Escaping competition and kinship are believed to be key factors leading to dispersal. In a marine bryozoan, researchers found that larvae neither preferred nor avoided conspecifics or kin during settlement. Manipulative experiments showed that settler density reduced maternal fitness when neighbors were siblings. Limited kinship was also observed among adult neighbors in the natural population.

Summary: The study found that dispersal patterns in organisms vary significantly across different years and seasons, introducing positive temporal covariance among dispersal routes. Considering the variation in dispersal will be an important avenue for future metapopulation and metacommunity research across diverse taxa.

Summary: This study examined the crawling and ballooning dispersal characteristics of Fall Armyworm larvae, one of the world's most important corn pests. The study found that airflow is a crucial factor in larval ballooning and long-distance dispersal. These findings contribute to field monitoring and control strategies against Fall Armyworm.

Summary: Terrestrial organisms rarely possess optical transparency, but some butterflies and moths have evolved transparent wings through loss of pigments and alteration of wing scales. In this study, we investigated the mechanism of wing transparency in the butterfly Phanus vitreus. We found that transparency is achieved by loss of pigments and vertical arrangement of normal scales, combined with an anti-reflective nipple array on exposed parts of the wing membrane. The blueish coloration of transparent regions is attributed to the properties of the wing membrane and local scale nanostructures.

Summary: This study conducted a comparative analysis of surface and deep ocean microbial communities and found that their spatial distribution is closely related to oceanic distance and environmental gradients. The dispersal rates and body sizes of prokaryotes and picoeukaryotes contributed to the differences in community similarity. In the deep ocean, both oceanic distance and environment played significant roles in shaping microbial spatial distribution, while in the surface ocean, the influence of the environment was stronger.

Summary: This study investigates the position, size, and density of taxon-specific patches of millions of organisms representing 36 taxa in the continental and oceanic environments of a subtropical western boundary current. The relationship between patch count and background density varies, with organism size explaining a significant portion of the variance in patch length. The predominant length scale of patches is phylogenetically random and predominantly <100 meters for 64% of taxa, indicating potential social and coactive processes in patch formation among diverse plankton species.

Summary: Swimming organisms can actively adjust their behavior in response to the flow around them. The response of larvae to turbulence may depend on both the time-averaged flow and the instantaneous flow.

Summary: The study discusses the evolution of complex life cycles, proposing three hypotheses on how selection may affect organisms with complex life cycles. It suggests a within-generation experimental design to gain insight into composite selection across life cycle stages. Sampling requirements for many systems are challenging but achievable, with plants and marine invertebrates being excellent systems for exploring how organisms with complex life cycles may adapt to climate change.

Summary: This study evaluates the potential for thermal stratification to provide refuge for Chinook Salmon and Delta Smelt in the San Francisco Estuary. The results show that fish may seek cooler refuge at the bottom of the water column during the peak of summer and in the afternoons. Thermal stratification may increase with climate warming, becoming more important for at-risk fish species in the future.

Summary: Temperature is a crucial factor that affects ecosystems at various scales. The rise in global temperatures is expected to have significant impacts, particularly in valuable systems like estuaries. In the upper San Francisco Estuary, which is an important water source and home to economically and ecologically valuable fish species, water temperatures have increased by an average of 0.017 degrees C per year over the past 50 years. The increase in temperature has been most significant in the late-fall to winter and mid-spring seasons, which coincide with important life stages of Chinook salmon and the endangered delta smelt. The study also found that warming was fastest in northern regions, which are crucial for fish migration and have important wetland habitats. However, no long-term temperature trends were observed in October, and only some regions showed trends in May, July, and August.
