Summary: This study examined the gene expression of two genotypes of Daphnia pulex under high and low food levels, and found that only the JPN2 genotype produced resting eggs at low food levels. Sixteen candidate genes were identified that showed changes in expression before resting egg production. These genes may be involved in the regulation of resting egg production in Daphnia.

Summary: Diapause is a physiological adaptation that allows animals to survive and conserve energy in unfavorable conditions. This adaptation is regulated by endocrine signaling, particularly in insect diapause. Recent research suggests a possible overlap between diapause endocrinology and the biology of aging, providing insights into lifespan determination.

Summary: The study found that changes in mitochondrial ROS levels and COXIV expression can affect diapause occurrence and pupal lifespan in Helicoverpa armigera. PKA and TFAM are also involved in this process, and G6PD activity plays a crucial role in maintaining ROS levels.

Summary: The study assessed the presence of microplastics in Flathead Lake and found that the concentrations were similar to other lakes in less populated areas worldwide. The research also suggested that precipitation might enhance the deposition of microplastics.

Summary: A new pathway, ROS-CK2-MKP3-p38, is found to regulate HIF-1 alpha activity for diapause in insects. High ROS levels in diapause-destined pupae's brains lead to low CK2 activity, resulting in reduced expression of MKP3 and increased p-p38 levels, which in turn regulates diapause through phosphorylation of HIF-1 alpha.

Summary: Changing climate and land use activity are causing changes in the inputs of colored dissolved organic carbon (cDOC) into lakes, leading to reduced water transparency and altered lake physicochemistry. Understanding the driving factors and effects of cDOC changes is crucial for managing the impacts of climate change on lake ecosystems.

Summary: The use of parthenogenetic silkworm strains is useful for maintaining transgenic clonal lines, but the efficiency of downstream transgenesis techniques is relatively low. This study aims to optimize the use of transgenesis in parthenogenetic individuals and found that the timing of embryo microinjection is a crucial parameter. The modification of the original method increased the efficiency of transgene injection and survival rate.

Summary: This study found that diapause-destined pupae of the moth Helicoverpa armigera have higher levels of protein carbonylation in the brain compared to nondiapause-destined pupae. The study also showed that ROS activate Akt, which phosphorylates CREB and facilitates its nuclear import, leading to the regulation of CBR1 expression and reduction of protein carbonyl levels.

Summary: The complexity of urban green space vegetation plays a vital role in predicting biodiversity, particularly for bird species. This study examined bird diversity in five urban mountain parks in southeast China and found that sparse forests support more bird species and higher diversity. Tree diversity significantly affects bird diversity, and the average subbranch height of trees influences bird evenness. The number of tourists and predators have minimal impact on bird diversity.

Summary: In this study, the molecular mechanisms underlying the long-term evolutionary adaptation of the mountain butterfly Parnassius glacialis to different environmental conditions were investigated. Gene expression patterns related to diapause, hormone biosynthesis, energy metabolism, and immune defense were identified and found to be correlated with habitat-specific adaptability. Duplicated genes promoting plastic responses to diverse environmental conditions were also identified. These findings shed light on the successful colonization and diapause evolution of the mountain Parnassius butterfly species.

Summary: The study compared the impact of introducing westslope cutthroat trout into fishless and nonnative trout lakes on littoral benthic invertebrate communities. The results showed that introducing this native trout species may alter invertebrate communities in a similar way to nonnative trout, highlighting the importance of risk assessments for trout recovery actions. Future research should focus on identifying potential cascading trophic effects on species subsidized by invertebrate prey.

Summary: This study evaluated the environmental genotoxic load in mountain and alpine habitats of Slovak mountains using Pinus mugo as a phytoindicator. The results showed contamination from distant sources, including long-range transboundary pollutants. The study also identified the influence of different altitudes and slope exposures on genotoxicity and pollutant sources.

Summary: The ability to respond to environmental changes is crucial for coping with the stressors related to climate change. This study investigated the call plasticity in a tropical and a temperate population of Neoconocephalus triops, and found that the pulse rate and call structure can undergo quantitative and qualitative changes in response to different environmental conditions. The findings highlight the evolutionary potential of hidden genetic variation and phenotypic plasticity in rapidly changing environments.

Summary: The chemical composition of sediments from Lake Bolshoy Vudjavr in the Russian Arctic zone was studied. The sediments have been heavily polluted by wastewater from apatite-nepheline production and atmospheric fallout, resulting in the enrichment of alkali and alkaline earth metals, N, P, and other elements. The pollution level of the sediments increased significantly after the launch of the Apatite Plant.

Summary: A study using paleolimnological methods revealed the long-term genetic dynamics of an obligate parthenogenetic panarctic Daphnia pulex population during colonisation and establishment in Lake Fukami-ike, Japan. The research showed that limited genetic diversity did not impede the population from establishing and thriving in a new habitat. Successful colonisation of the lake was achieved by different haplotypes, with two lineages coexisting towards the end of the study period.

Summary: Microplastic pollution is currently one of the most intensely studied ecological issues. The presence of microplastics affects the proportion of individuals of coexisting species and the elimination rate of the inferior competitor. Different types of microplastics have different effects on the density of competing species.

Summary: Artificial light at night has been found to alter natural light patterns and have ecological impacts. However, there have been limited studies on its effects on organism interactions in aquatic environments. To address this gap, a preliminary enclosure experiment was conducted to examine the foraging effect of juvenile perch on a zooplankton community under the presence of artificial light. The results showed that even short exposure to artificial light can lead to increased fish predation and impact zooplankton populations.
