Summary: Marine heatwaves can have carryover effects on the larval microbiome, settlers growth rate, and metamorphosis duration of sponges. The microbial community of adult sponges changed significantly after exposure to heatwave conditions. Sponge larvae derived from heatwave-exposed sponges showed an increase in endosymbiotic bacteria. Settlers derived from heatwave-exposed sponges had a higher growth rate but delayed metamorphosis compared to settlers from control sponges.

Summary: The interaction between genetic divergence and phenotypic plasticity is important in understanding geographic variation in insects. Temperature and photoperiod are key factors in shaping insect life histories. This study investigates the survival, development, and body mass of three populations of Cassida vibex beetles from different geographic locations, revealing subtle but significant differences in these traits and their plasticity to temperature and photoperiod.

Summary: This study investigates the impact of diet quality on developmental rates and survival of freshwater detritivorous isopods, showing how diet quality and composition can generate substantial phenotypic variation by affecting growth and pigmentation rates during development in the absence of predation.

Summary: Finding the balance between survival and reproduction is a central problem in life-history theory. The terminal investment hypothesis predicts that individuals facing a survival threat will increase immediate reproductive investment to maximize fitness. However, research on this hypothesis has yielded mixed results. In this study, a meta-analysis was conducted to examine reproductive investment in multicellular animals after an immune challenge. The results provided some support for the hypotheses, showing stronger terminal investment responses in older individuals with lower residual reproductive values, as well as an increase in variance, particularly in longer-living species.

Summary: The study shows that maternal effects play a role in mediating the trade-off between growth and survival of lizard offspring in response to climate warming. Offspring in warm climate conditions grow faster, but there is a decrease in survival rate when offspring are from maternal present climate treatment. These findings highlight the importance of adaptive maternal effects in response to climate change.

Summary: Current research on the interaction between maternal nutrition and developmental programming in male offspring primarily focuses on the effects of maternal diet on female offspring, with less attention on male offspring. Poor maternal nutrition can lead to various maladaptive phenotypes in offspring, but the specific outcomes in male offspring remain poorly understood.

Summary: Predicting the effects of climate change on plant-insect herbivore interactions is challenging, with responses to water limitation-induced host plant quality change in a Glanville fritillary butterfly metapopulation showing marked variability. Intraspecific variability in plasticity suggests potential for buffering against drought-induced changes in host plant quality within the Finnish M. cinxia metapopulation.

Summary: Environmental novelty and latitude do not affect the developmental plasticity and broad sense genetic covariance matrices (G) of damselfly populations, but photoperiod does. Specifically, photoperiod increases evolvability in damselfly populations under strong seasonal time constraints, leading to higher levels of adaptive divergence and developmental plasticity.

Summary: This study investigates the effects of winter temperatures on the population dynamics, development, and reproduction of predatory stink bugs in subtropical regions. The research reveals that E. furcellata undergoes winter dormancy and the proportion of adults is higher during the cold winter months.

Summary: Environmental conditions play a crucial role in plant reproduction, as changes in climate can disrupt seed germination and dormancy, affecting plant diversity and suitable habitats. The adaptive mechanism of seed dormancy can help buffer against the negative impacts of environmental changes, highlighting the need to understand how temperature and humidity influence seed germination patterns. Integrating research techniques from different biology disciplines, such as transcriptomics and proteomics, can aid in understanding the processes controlling seed germination.

Summary: In marine fishes, the timing of spawning and maternal effects can influence the survival of offspring. This study examined egg traits and found that intrinsic differences among females or spawning waves are unlikely to significantly contribute to the poor survival of early-season progeny. Other extrinsic factors or processes, such as seasonal match-mismatch dynamics with prey, are more likely causes of mortality.

Summary: In this study, we investigated the effects of phenolic compounds from hydrophytes on the survival and reproduction of rotifers. The results showed that these compounds influenced the age-specific survival, lifespan, and reproductive rates of the rotifers, but their effects depended on other chemicals released into the medium.

Summary: Dopamine plays an important role in regulating responses to food abundance, but the costs of high dopamine levels are poorly understood. This study investigates the effects of maternal dopamine levels on offspring fitness in the water flea Daphnia magna. The results show that although dopamine-exposed mothers produced smaller offspring, these offspring had a superior starvation resistance compared to controls.

Summary: Maternal resource availability and metabolism have a limiting effect on reproductive output. Allomaternal care and domestication increase maternal energy, leading to an increase in reproductive output. Different forms of external energetic supplementation have varying effects on fertility increase.

Summary: Research shows that the assumption of isometry in the management models of fisheries leads to an overestimation of the replenishment potential of exploited fish stocks, risking systematic overharvesting. By considering hyperallometric reproduction, management strategies could be optimized to increase yields and maintain target replenishment levels.
