Summary: The study explores how parents' perceived social environment can impact offspring behavior, particularly in daughters. Offspring reared in a no-song environment were more active, while daughters of parental pairs with both parents reared in a song environment showed lower levels of mobility compared to other groups.

Summary: This study investigates the transgenerational inheritance of environmentally induced DNA methylation in water fleas. The results suggest that environmentally induced DNA methylation is non-random and stably inherited across generations in water fleas, potentially playing a significant role in the eco-evolutionary dynamics of freshwater communities.

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: In the last decade, epigenetics has become a central discipline in the field of biogerontology, as age-associated epigenetic changes are linked to various pathologies and epigenetic clocks can correlate biological age with chronological age. Recent empirical observations also suggest that inherited epigenetic effects could influence lifespan/longevity in different organisms. This review critically evaluates these effects from an evolutionary perspective, aiming to integrate the evidence with the main evolutionary theories of ageing.

Summary: Research has shown that there are genetic differences in the transmission and expression of environmental effects, and these differences are likely to evolve in response to natural selection in different environments and sequences of environments.
Experimental manipulation of temperature environments in Arabidopsis thaliana revealed variations in the temporal persistence and environmental stability of temperature effects among different genotypes.

Summary: This study found that clonal parental nutrient effects can regulate interspecific competition between Pistia stratiotes and Eichhornia crassipes by altering the competitive ability of P. stratiotes. These effects are related to resource provisioning and DNA methylation mechanisms.

Summary: This study found that copper excess can alter offspring fitness in the duckweed Spirodela polyrhiza under recurring stress in a time- and genotype-dependent manner. The effects of copper excess on plant growth rates and offspring fitness were influenced by environment-induced transgenerational responses.

Summary: Low doses of commonly used pollutants can induce genome-wide differences in cytosine methylation in freshwater crustaceans, and these effects can persist for more than 7 months, transmitting to up to 15 generations. The differential methylation induced by pollutants mainly occurs at sites that are highly methylated in control populations, and these differences may have long-lasting effects on phenotypic development.

Summary: This study demonstrates that low doses of pollutants can induce transgenerational epigenetic effects in freshwater crustaceans, affecting the methylation patterns of the genome. These effects can persist for multiple generations and can be inherited even after the removal of the pollutant. The altered methylation levels may lead to phenotypic changes and potentially contribute to the adaptation or extinction of populations facing anthropogenic stressors.

Summary: The research demonstrates that prey species can develop defense mechanisms through inducing phenotypic plastic traits in response to predator threats. Observations in the experiment show that transgenerational induced phenotypic plasticity can shorten the lag phase of defense trait formation, helping prey species mitigate long-term predation risks.

Summary: The study revealed that paternal exposure to different environmental stimuli before fertilization can have specific effects on offspring traits, such as increasing offspring responsiveness to simulated predation risk when exposed to a native predator or reducing antipredator behaviors when exposed to an artificial stimulus. Offspring did not show a stronger response to the stimulus encountered by their fathers, but were generally more responsive to a native predator compared to non-native predators.

Summary: Organisms are facing increasing stress from multiple factors, and the interaction between these factors can have unpredictable impacts. Phenotypic plasticity allows organisms to quickly respond to changes in their environment, both within a generation and across generations. It is unclear how biotic and abiotic stressors collectively affect transgenerational plasticity and whether this plasticity is adaptive. This study tests the effects of environmental changes on transgenerational plasticity using a Daphnia-Metschnikowia zooplankton-fungal parasite system, and finds that transgenerational plasticity induced by temperature and parasite stress influences host fecundity and lifespan, but is unable to mitigate the negative effects of parasite infection.

Summary: Competition between parent plants in moist soil may lead to specific developmental effects in the next generation that are beneficial for light-limited offspring, while competition in dry soil may produce slightly lower quality offspring. These results indicate that competitive conditions during the parental generation can significantly contribute to offspring variation, depending on the abiotic resources available to both parents and progeny.

Summary: The environment experienced by one generation can impact the phenotypes of future generations, transmitted through parental cues at different time points. Results suggest that changes in paternal care behavior do not affect offspring traits, indicating that paternal care neither amplifies nor compensates for the phenotypic effects induced by sperm, and nongenetic changes induced by sperm may occur independently of nongenetic changes induced by paternal care.

Summary: Research has uncovered differences in gene expression between two species of spadefoot toads in response to a shared environmental risk, particularly genes related to lipid, cholesterol, and steroid biosynthesis and metabolism. These differences may have played a crucial role in the genetic accommodation of developmental plasticity in this biological system.

Summary: Ocean acidification and warming are important stressors for marine organisms. Different populations of great scallops from France and Norway showed varying responses to temperature and PCO2 variation, with French spat exhibiting more metabolic plasticity but decreased survival compared to Norwegian spat under elevated temperature. Understanding the acclimatization potential and physiological plasticity among populations is crucial in predicting species responses to climate change.
