Global warming and rising surface temperatures are adversely affecting organisms. As the use of pesticides increases, concerns about their impacts on non-target organisms are growing. However, climate warming and pesticides may interact to produce combined effects on organisms. In this study, we exposed the geckos (Gekko japonicus) to different doses of spirotetramat (0, 15, and 30 mg/kg) and at different temperatures (25 °C and 30 °C) for 30 days. To investigate the effects of warming and spirotetramat on the trade-off in life-history traits of G. japonicus, we analyzed the energy allocation of the geckos under environmental stress. The results showed that females tended to allocate a significant amount of energy for self-maintenance and reduce investment in reproduction, which is a "conservative" life-history strategy. In contrast, males adopted a "risky" life-history strategy, tending to increase investment in reproduction while reducing immunity. However, in the long run, both reducing energy allocation towards reproduction and reducing investment in immunity can have adverse effects on the sustainable development of the population.

Biocontrol techniques that impair reproductive capacity of insect pests provide opportunities to control the dynamics of their populations while minimizing collateral damage to non-target species and the environment. The Trojan Female Technique, or TFT, is a method of the trans-generational fertility-based population control through the release of females that carry mitochondrial DNA mutations that negatively affect male, but not female, reproductive output. TFT is based on the evolutionary hypothesis that, due to maternal inheritance of mitochondria, mutations which are beneficial or neutral in females but harmful in males can accumulate in the mitochondrial genome without selection acting against them.

Daphnia's antipredator responses are regulated largely by the nervous system, making these responses particularly susceptible to compounds that impact neurodevelopmental or neurofunctional processes. This study aimed to determine the molecular pathways involved in modulating the effects of scopolamine on inducible antipredation responses triggered by fish kairomones. We used two clones showing two contrasting responses.

The human capacity for culture is a key determinant of our success as a species. While much work has examined adults' abilities to create and transmit cultural knowledge, relatively less work has focused on the role of children (approx. 3-17 years) in this important process.

Atrazine is a predominant herbicide globally, and its residues are commonly found in natural water bodies due to its extensive use. Atrazine is known for its detrimental effects on the reproductive abilities of aquatic plants and animals. Our study explored the impact of maternal exposure to atrazine on the survival and performance of offspring using the water flea Daphnia magna as a model organism.

AbstractInducible defenses can affect the persistence, structure, and stability of consumer-resource systems. Theory shows that these effects depend on characteristics of the inducible defense, including timing, costs, efficacy, and sensitivity to consumer density. However, the expression and costs of inducible defenses often vary among life stages, which has not been captured in previous unstructured models.
