Summary: This study investigated the thermal plasticity of Daphnia galeata, a freshwater zooplankton, focusing on the rigid setae of its second limb. The results showed that temperature had a significant effect on the length ratios of the rigid setae, indicating thermal plasticity. Allometry, the relationship between body size and setae length, also differed significantly among different temperatures. The study concluded that rapid thermal plasticity in non-filtering limbs is more important than previously thought for Daphnia.

Summary: This study investigated how Daphnia transmit predation risk information to their offspring through a prolonged experiment. The results showed that the offspring's inducible defensive traits were mainly determined by their own environment rather than their mothers' experience. Moreover, as the mothers produced more broods of offspring, the inducible defensive traits of the offspring gradually increased and then decreased.

Summary: Naturally regenerated Norway spruce plants were found to have stronger chemical defenses compared to nursery-grown plants, with higher concentrations of phenolic compounds and lower concentrations of terpenes. However, treatments such as wounding or MeJA did not significantly affect whether plants were attacked by pine weevils. Further research is needed to understand the importance of plant age, stress level, genetic origin, and resource availability for the chemical defense mechanisms of young Norway spruce plants.

Summary: Facultative clonality is associated with complex life cycles where sexual and asexual forms can be exposed to contrasting selection pressures. Studying coexisting sexual and asexual Hydra oligactis polyps, a freshwater cnidarian, we found high relatedness among populations and evidence of hydras spreading through zoochory. Despite no genetic structure with respect to mode of reproduction, the study revealed phenotypic plasticity and cases of apparent sex change within the same clonal lineages.

Summary: This study examines the impact of the speed of inducible defences on species coexistence, biomass distribution, and temporal variability using a model. The results show that higher switching rates reduce individual fitness, increase consumer biomass, and decrease total autotroph biomass. Maladaptive switching also strongly decreases autotroph coexistence.

Summary: Female reproductive fluids (FRFs) play crucial roles in reproductive functions, but their interactions with sperm under different environmental conditions are not well understood. This study investigated the effects of ejaculate age and FRF on sperm traits in a mussel species and found that FRF altered the effects of ejaculate age on sperm motility, with longer-lived sperm exhibiting stronger responses to FRF. There was also significant variation among males in the relationship between sperm motility and ejaculate age, which was only observed in the presence of FRF. These findings highlight the importance of considering female reproductive physiology in understanding sperm phenotypic plasticity.

Summary: In freshwater environments, aquatic grazers face challenges when the quantity and quality of food are suboptimal. A life table experiment on Daphnia magna examined the effects of food quantity (algae concentration) and quality (cyanobacteria diet) on life histories and resource allocation strategies. Growth-related traits were affected similarly under different food regimes, but reproductive strategies differed between animals exposed to low food quantity and quality. These findings suggest that different resource allocation strategies (number vs size of eggs) may be adaptive under specific food regimes.

Summary: This study identifies the fish-derived chemical signal, bile salt 5 alpha-cyprinol sulfate (5 alpha-CPS), as the kairomone that induces morphological defensive structures in the invasive species Daphnia lumholtzi. Experiment results confirm that exposure to purified 5 alpha-CPS induces significantly elongated helmets and spines in D. lumholtzi. These findings reveal the evolutionary conservancy of the molecular mechanism behind inducible defenses in Daphnia species against fish and suggest the ecological relevance of 5 alpha-CPS in predator-prey communication between Daphnia and fish.

Summary: Phenotypic plasticity is considered a hallmark of cancer, but the dynamics of this process are still poorly understood. Recent investigations using a systems-level perspective have shed light on specific dynamical hallmarks of phenotypic plasticity in different cancers. Understanding the dynamic features of phenotypic plasticity may be crucial in shifting the paradigm of cancer treatment towards a more predictive and proactive approach.

Summary: This study investigated the phenotypic responses of native Olympia oyster populations in California estuaries to an invasive predator, the Atlantic oyster drill. The oysters displayed different phenotypic changes and protein expressions in response to the invasive predator, suggesting local adaptation and trade-offs between biomineralization and immune function. This research provides insights into the mechanisms underlying inducible defences and the plasticity of prey organisms.

Summary: This article examines the rate at which reversible phenotypic plasticity (RPP) occurs and its potential impact on how organisms overcome environmental challenges. The study suggests that current theoretical models do not consider the evolutionary potential of RPP rates. If the rate of plasticity itself can evolve, it may alter the organism's perception of environmental predictability and influence the slope of the evolved reaction norm. The optimization of phenotypic plasticity rates, their evolutionary dynamics in different environments, and the costs associated with them warrant further exploration in future research.

Summary: The study found that heat tolerance differences in Daphnia magna may be related to metabolic compensation rather than genetics. Additionally, D. magna acclimated at 25 degrees Celsius showed a greater ability to slow down respiration at high temperatures compared to those acclimated at 10 degrees Celsius.

Summary: The temporal hybrid superiority hypothesis suggests that seasonal variability in temperate lakes provides hybrid clones with a temporary fitness advantage, leading to their long-term coexistence with maternal taxa. The average fitness of hybrids surpassing that of parental clones over longer periods could also maintain their presence. Phenotypic plasticity and developmental noise were compared among hybrid and maternal clones in response to various stress factors. Hybrid clones exhibited the broadest phenotypic plasticity, suggesting their ability to adapt to different environmental conditions.

Summary: The study found that plant genotype and phenotypic plasticity have the greatest impact on rhizosphere microbiota, while chemical inputs such as fertilizer, fungicide, and herbicide have minimal effects. Phenotypic plasticity is particularly important in explaining variations in bacteria and fungi diversity, but does not affect mycorrhizal associations.

Summary: Recent evidence suggests that the presence of predators can influence the colonization rates of prey in nearby predator-free patches, with effects potentially being positive or negative based on predator- and prey-specific factors. The distance from predator patches also plays a role in shaping these responses, highlighting the complexity of habitat selection in landscapes.

Summary: Acantholeberis smirnovi, a new species of cladocera, was recently discovered in the Andean habitats of South America. This species differs morphologically, ecologically, and biogeographically from other species in the region. It is adapted to live in acidic water bodies, but the newly discovered species is found in temporary ponds near the Atlantic Ocean in Brazil, which is unique compared to other species.

Summary: Riverscape aggradation caused by deposition of fine particles on forest litter can have detrimental effects on soil, sediment, and water properties, as well as riparian vegetation. The addition of forest litter can mitigate erosive processes and improve water quality in disturbed areas, representing a sustainable and low-cost nature-based solution for riparian restoration.

Summary: The study found that increasing concentrations of aquatic humic substances resulted in a decrease in zooplankton density and biomass, with more microphage organisms present in high HS environments, possibly due to the increased importance of the microbial-loop. This indicates the potential for certain species to act as bioindicators for HS presence and highlights the indirect effects of HS on the structure and composition of primary consumers.
