Summary: The freshwater copepod Hesperodiaptomus shoshone exhibits mild behavioral changes in response to a small-scale turbulent vortex, which are dependent on sex and vortex orientation. Unlike marine copepods, H. shoshone swims with relatively linear trajectories across different turbulence intensity levels. Differences in morphology, environmental conditions, or ecological niche may explain the contrasting response to the turbulent vortex.

Summary: The research indicates that a single exposure to cold stress can reduce the mating success of male crickets, but after some chemosensory contact with a female, most males were able to produce spermatophores and mate successfully.

Summary: This study demonstrates the influence of Ni substitution on the structural, dielectric, and ferroelectric properties of single-phase Pb-doped BaTiO3 ceramics. The hydroxide co-precipitation method was used to fabricate the materials. The substitution of Ni resulted in changes in the crystal structure and decreased the ferroelectric-paraelectric transition temperature. The composite with a higher Ni concentration exhibited the highest magnetodielectric coupling coefficient.

Summary: This study presents the first report on the mate-seeking behaviors of the calanoid copepod Eodiaptomus japonicus. The analysis reveals that males exhibit different pursuit patterns in seeking mates and use hydromechanical signals to locate females. Females display a behavior to shake off males, indicating the existence of mate choice.

Summary: We investigated the effects of structural isomerism on the properties of block copolymers (BCPs) using experiments and molecular dynamics simulations. By synthesizing structural isomeric BCPs and measuring their domain periodicity, we found that the dipole moment orientation of the thiols significantly affects microphase separation. This work provides new insights into the structure-property relationship of BCP materials and offers a useful tool for molecular engineering of BCPs.

Summary: We provide evidence that the freshwater parasitic copepod, Salmincola californiensis, can act as a vector for the bacterium Aeromonas salmonicida. Through various experiments, we found that fish infected with copepods developed furunculosis caused by A. salmonicida. We also detected fluorescently labelled A. salmonicida in copepod egg sacs and successfully cultured the bacterium from egg sacs collected from infected adult Chinook salmon in a freshwater hatchery.

Summary: This study examines the impact of sleep on courtship and egg-laying behaviors in animals, finding that sleep duration, depth, and pressure can affect reproductive success, with a more significant impact on male courtship behavior. Additionally, sleep phenotypes are less influenced by social experiences, while egg-laying behavior is less sensitive to sleep length and parameters indicative of switching between sleep and wake states.

Summary: The study evaluated the impacts of adult density on key biological parameters of the tropical estuarine copepod A. tropica, finding that a density of 1000 adults/L resulted in highest relative egg production and overall productivity. Conversely, the highest adult mortality and nauplii cannibalism were observed at a density of 2000 adults/L. Additionally, the population with an initial density of 2000/L stabilized at 1000 adults/L after 8 days culture.

Summary: An extensive Metropolis Monte Carlo simulation is conducted to study the magnetic and thermodynamic behaviors of a trilayered spin-1/2 Ising ferrimagnet with square monolayers driven by a Gaussian random magnetic field. The compensation phenomenon and the shifting of critical points are observed as the strength of the random field varies. Islands of ferrimagnetic phase without compensation emerge as the standard deviation of the field increases, and the scaling relation between the standard deviation and the area of these islands is determined.

Summary: The relative frequency of sexual and asexual reproduction plays a significant role in the distribution of genetic diversity within and among populations. However, the variation in the rates of sexual and asexual reproduction across different eukaryotes, especially among the three major lineages of macroalgae, remains poorly characterized. This study focuses on freshwater red macroalgae and reveals patterns of switching between monoicy and dioicy, similar to brown macroalgae and angiosperms. Understanding the evolutionary consequences of selfing and asexual reproduction is crucial for studying the evolutionary ecology of algae and eukaryotic evolution in general.

Summary: Research indicates that the global economic cost of aquatic invasive alien species has reached $345 billion, with the majority attributed to invertebrates, vertebrates, and plants. The highest costs were reported in North America and Asia, primarily due to resource damages. The costs of aquatic invasive species have increased exponentially in recent decades, but are likely underreported.

Summary: Invasive species have caused significant economic losses in North America, with costs increasing over the years from an average of $2 billion per year in the 1960s to over $26 billion per year in the 2010s. The United States has incurred the highest costs among North American countries, even after accounting for research efforts.

Summary: The concept of invasion is useful in various contexts from cancer tumors to ecosystems. While the field of invasion genetics lacks good reference genomes and rigorous studies, cancer research benefits from extensive resources to examine genome level dynamics. The detailed studies of behavior in human cancers offer novel insights for understanding genome level dynamics in a variety of invasive species.

Summary: The portfolio effect, which refers to opposing fluctuations in individual populations tempering community scale variability, was found to be strong in theoretical models but weak in empirical data. Various factors such as shared environmental responses and interspecific competition may influence this discrepancy. Furthermore, geographical location and habitat types were observed to contribute to variations in population and community dynamics.

Summary: This study quantifies the overall costs of invasive species in the United States using a novel global database and finds that these costs have been increasing over time, mainly driven by resource damages and losses, with agriculture being the most impacted sector. Mammals and insects are identified as the taxonomic groups responsible for the greatest costs.

Summary: The global increase in biological invasions is putting pressure on ecological and economic systems. However, the lack of standardized measurements across spatial, taxonomic, and temporal scales makes it difficult to assess the effectiveness of current management expenditures. Geographic distribution of management costs heavily favors North America and Oceania, with most expenditures directed towards invasive alien invertebrates in terrestrial environments.

The species composition differences between primary and regenerating forests can influence the trajectory of spillover risk. Factors such as forest regeneration rate and the relative spillover risk of regenerating forests determine landscape-level spillover risk.

Summary: Wetlands provide essential ecosystem services and are sensitive to changes in wetland hydrology. The study in west-central Florida investigated the sources of variation in wetland inundation and found that water levels and hydroperiods were affected by factors such as precipitation, groundwater extraction, and land development. Water conservation policies led to an increase in wetland water depths and longer hydroperiods, but some wetlands did not show signs of hydrological recovery. The study highlights the importance of recognizing the sensitivity of wetland inundation to groundwater extraction during periods of low precipitation.
