Summary: Phenotypic variations between populations are often related to climatic variables. In this study, the phenotypic variation of Xenopus laevis tadpoles in two regions with contrasting rainfall regimes in southern Africa was found to be driven by both adaptation and plasticity. However, the reaction norms differed between populations, indicating adaptive and asymmetric plasticity.

Summary: Seasonal plasticity in insects is often triggered by temperature and photoperiod changes. This study investigated the impact of cuticular hydrocarbon (CHC) profile changes on mate recognition and mating success in Drosophila suzukii summer and winter morphs. The results showed that CHC compositions differed with age and morphs, but not between the sexes of the same age and morph. The behavioral assays revealed that summer morph pairs exhibited earlier mating, shorter duration, and higher offspring production compared to winter morph pairs.

Summary: This study provides new insights into the invasion processes of the harlequin ladybird into other continents from its native range in Asia. It identifies a population in eastern China as the source of non-native populations and identifies potential adaptive genomic loci related to body color variation, visual perception, and hemolymph synthesis. The study also reveals asymmetric migration, varying population sizes, historical bottlenecks, and different mitochondrial haplotypes between native and non-native populations.

Summary: Global warming is affecting the phenology, life-history traits, and biogeography of species. This study examines the life-history traits of two successful range-extending fish species and finds that populations at higher latitudes have shorter reproductive periods, slower growth rates, but higher fecundity and longer lifespans.

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: Phenotypic plasticity allows individuals to respond to new environments, but the study found fixed phenotypic plasticity within bacterial lineages despite different environments and limited evolutionary changes in heat tolerance. Bacteria in hot springs show higher heat tolerance compared to those in temperate lagoons, surviving as spores and completing their life cycles during intermittent moderate temperatures. These findings highlight the potential negative impact of climate change on biological cycles that depend on microorganisms.

Summary: Understanding long-term changes in life-history traits of freshwater fish species is crucial for assessing and managing fisheries. This study compared the life-history traits of a native fish species in different periods and found that modern fish exhibit more opportunistic traits, larger size, faster growth, earlier sexual maturity, and increased fecundities compared to historical samples, which had larger size, higher age class diversity, and delayed sexual maturation. Fast growth towards early sexual maturation and reduced body sizes are associated with destabilized populations and ecosystems.

Summary: The impacts of environmental constraints during development on the behavioural response of fishes are not well understood. This study examined how early exposure to the pyrethroid insecticide permethrin influenced phenotypic traits in mangrove rivulus fish. The results showed that larval exposure to high concentration permethrin led to slower growth, decreased activity, negative thigmotaxis, and reduced prey capture. Additionally, adult fish previously exposed to high concentration permethrin showed overcompensated growth and altered aggression behavior during contests. This study highlights the immediate and persistent effects of permethrin on phenotypic traits and suggests an interaction between pyrethroids and hormones in affecting animal behavior.

Summary: In trait-based ecology, it is common to use measures to quantify phenotypic variation between populations. However, these measures overlook the within-population trait variability and some of them cannot be partitioned between populations. This study proposes a new measure called the phenotypic dissimilarity (PhD) index to address these issues and provide a tool for quantifying phenotypic variation within and between species.

Summary: This study aimed to investigate the effects of larval dietary sucrose on the life history traits, stress tolerance, and defense response at the molecular level of Bactrocera dorsalis. The results showed that low-sucrose diet led to decreased body size, shortened developmental duration, and enhanced sensitivity to beta-cypermethrin, while high-sucrose diet increased developmental duration, adult fecundity, and tolerance to malathion. Transcriptome analysis revealed differentially expressed genes related to metabolism, hormone synthesis and signaling, and immune-related pathways. This study provides insights into the phenotypic adjustments and strong host adaptability of oriental fruit flies in response to dietary conditions.

Summary: This study investigates the plasticity and evolution of trait changes in damselflies during their range expansion into a warmer region. The results suggest that the populations have evolved adaptive changes in terms of a faster pace-of-life, smaller body size, higher energy budget, and increased expression levels of the heat shock gene DnaJ. However, there is incomplete convergence towards the native sister species for thermal plasticity in traits associated with anaerobic metabolism and melanization.

Summary: This study proposes a theoretical framework for immune cell phenotypic classification based on gene plasticity, and suggests that loss and gain of phenotype are accompanied by changes in gene plasticity. Transcriptome data analysis from multiple immune cell types supports the logical rationality and generality of this framework, providing a new perspective on understanding diverse immune cell phenotypes and intrinsic regulation in the immune system. Moreover, the results obtained provide a useful resource for big-data-driven experimental studies and knowledge discoveries.

Summary: Due to the continued degradation of wetlands and the rapid decline of freshwater biodiversity, it is necessary to identify vulnerable species for conservation and management efforts. In this study, we assessed the vulnerability of branchiopod communities in dryland landscapes using egg bank abundance and morpho-species richness as indicators. Our results showed that the branchiopod communities became more vulnerable along an aridity gradient and that egg bank abundance decreased with alkalinity.

Summary: Large branchiopods are crucial for temporary ponds' ecosystems and their disappearance in Tanzania due to human activities is a concern. In this study, we compared temporary ponds in protected areas with those in communal lands, and found that land-use types affect the structure of large branchiopod community. We found six large branchiopod species, including one new species, and identified the most abundant and widely occurring species. The variation in community structure was influenced by the presence of Nothobranchius killifish and orthophosphate concentration. Understanding the relationship between land-use types and large branchiopod communities can guide the management of temporary pond ecosystems.

Summary: Increasing pCO(2) in freshwater environments may lead to acidification, which could negatively affect the survival, growth, and calcification of freshwater organisms. In this study, elevated pCO(2) and associated acidification were found to reduce the survival and calcium content of Daphnia magna, as well as slow down their growth and delay maturity. This is likely due to interference with the calcification process under elevated pCO(2) and low pH conditions.

Summary: Environmental risks posed by widespread pesticide application have attracted global attention. Chemical risk assessments in aquatic environments typically rely on toxicity data from classic model species, but complementary data based on local species are needed for unusual living environments. This study conducted an environmental risk assessment of cypermethrin using local temporary pond species, and compared the results to those obtained using classic model species.

Summary: Ecosystems worldwide are being polluted by pharmaceutical compounds, which can disrupt wildlife behaviour. Despite a large body of literature, there is a lack of long-term studies across different life stages to accurately estimate the ecological outcomes of pharmaceutical pollution. In this experiment, fish exposed to the antidepressant fluoxetine showed smaller body size and changes in their position in the water column during adulthood, highlighting the importance of considering ecologically relevant timescales when studying the ecotoxicology of pharmaceuticals.
