Summary: The background of crop-wild hybridization has raised concerns due to potential gene flow and transgene escape. Results of a 3-year experiment show that hybrids between GM soybeans and wild soybeans exhibit lower seed germination and higher seed productivity compared to GM soybeans, with similar traits to wild soybeans. The presence of foreign protein is stable in EPSPS positive plants, and the EPSPS transgene does not affect hybrid vigor. Hybrids between GM soybeans and wild soybeans may have a greater impact on growth and fecundity, providing a potential competitive advantage.

Summary: The study found that amphibian density and encounter rate decreased with water-source proximity, but increased with pond-side grass height. Additionally, the likelihood of encountering amphibians in tilapia-only ponds was higher than in catfish-only or tilapia and catfish ponds.

Summary: Dispersal ability determines the distribution and abundance of species, and is influenced by environmental factors such as density, food availability, and predation. Food availability plays a central role in the spatial structuring of nematode communities.

Summary: This study aims to investigate the potential risk of gene flow from herbicide-tolerant transgenic soybeans to wild soybeans by measuring the fitness of hybrids under different planting conditions and analyzing the soil microbial communities. The results showed that the hybrids exhibited higher fitness in certain conditions, indicating that the gene from transgenic soybeans may be transferred to wild soybeans.

Summary: The study found that European consumers generally believe wild fish have higher quality, while farmed fish are seen as superior in terms of control, price, and availability. Despite a preference for wild fish, consumers actually consume more farmed fish, indicating that positive perceptions of products do not necessarily drive higher consumption.

Summary: Environmental changes can affect the nursery function of coastal areas by influencing the growth and survival rates of juvenile fish. This study collected wild sea bass juveniles and found that scale cortisol levels increase with age and differ across cohorts in 2019 and 2020, possibly due to older fish or heatwaves. Fish with high scale cortisol levels in these years also experienced impaired growth.

Summary: The study found that sea urchins adapt to food-limited environments by adjusting energy allocation between reproductive capacity and modifications to their foraging apparatus. In sea urchin barrens, reproductive capacity was lower and the morphology of the foraging apparatus was more elongate.

Summary: Anthropogenically-driven climate change and urbanization have significant impacts on mammalian body size, with larger individuals usually found in urban areas, supporting the resource availability hypothesis. This study also highlights the importance of life history and ecological factors in mediating the effects of climate and urbanization on body size.

Summary: The study found that through supplementary feeding, the abundance and behaviors of fish in a temperate South Pacific estuary showed a highly predictable pattern. Fish numbers and collective behaviors significantly increased during active feeding at the station, but decreased markedly when feeding was stopped.

Summary: This study investigated the spatial variation of stoichiometric traits of non-native sailfin catfishes in Guangdong province and analyzed the factors contributing to the variation. The study found that environmental factors such as climate, diet quality, fish species richness, and trophic status played a significant role in the variation of stoichiometric traits. Water chemistry, including total nitrogen and phosphorus, ammonia nitrogen, and soluble reactive phosphorus, had the most impact on stoichiometric traits.

Summary: Predator-prey interactions play a significant role in influencing the structure of fish communities. Hatchery fish are more vulnerable to predation compared to wild counterparts, especially as their body size increases. Increasing habitat heterogeneity can reduce predation rate in streams with mammalian predators, highlighting the importance of considering habitat diversity in management decisions for supporting wild fish populations.

Summary: In recent years, there has been a growing interest in animal cognition, especially fish cognition. This review provides examples of studies that use an ecological approach to study cognition in wild teleost fishes through field observations, field manipulations, and laboratory tests. The focus is on cases that have implications for understanding cognitive processes in endotherm vertebrates, showing that fishes possess supposedly 'complex' cognitive processes originally thought to require a more complex brain.

Summary: This study successfully developed a flexible cotton surface-enhanced Raman scattering substrate for detecting malachite green residues in fish, with a low detection limit of 0.05 ppm. The QuEChERS sample preparation method was used for SERS analysis, showing capability for multiplex detecting mixtures of MG and Dimetridazole at different ratios. The cotton fiber-Ag composite was suitable for detecting trace contaminants in food with simplicity and instantaneity.

Summary: This study analyzes the impact of declining biodiversity on nutrient supplies, particularly focusing on compensation, trophic dynamics, and functional diversity. The results show that when small sedentary species compensate for declines in large migratory species, there is an increase in fatty acid supplies but a decrease in zinc and iron supplies. Our findings emphasize the importance of considering biodiversity's essential role in sustaining nutritional benefits for the global population dependent on wild foods.

Summary: Artificial feeding of wildlife has positive and negative effects on both target and non-target species, with potential impact on interspecific interactions. This study used GPS telemetry data to investigate the spatiotemporal response of lynx to artificial feeding sites, and found that experience level played a role in site selection. Experienced lynx tended to avoid feeding sites, while inexperienced lynx were attracted to them, indicating a learning process in response to altered interactions.
