Summary: This study investigates the foraging behavior of the parasitoid Eretmocerus eremicus in relation to the number of hosts and the risk of predation. The results show that the number of hosts has a significant impact on the parasitoid's behavior, while the risk of predation has a relatively smaller effect.

Summary: By perceiving conspecific chemical cues, damselfly larvae are able to recognize the presence of other cannibals, which provides additional benefits for hunting and defense. However, it is unclear whether these cues inform individuals of danger or food availability in cannibalistic interactions. This study aimed to investigate the response of Ischnura elegans larvae to chemical cues from older conspecific larvae, and found that they exhibit anti-predator defense mechanisms in response to these cues, balancing prey-catching with staying safe.

Summary: Foraging involves a trade-off between food and safety, which is often associated with predation. However, danger and risk can arise from various causes and cannot be solely assessed based on predators. To provide a more comprehensive assessment of risk management, this study manipulated and measured risks by adding shelter and time-varying supplemental food to a population of meadow voles. The results showed that voles foraged more actively under safety, recognized least risk with access to both food and shelter, and exhibited sex-dependent habitat selection. This study highlights the need for ecologists to consider other dangers and processes that can alter foraging behavior and habitat selection, rather than attributing risk solely to predation.

Summary: This paper evaluated the impact of different genetic backgrounds on the estimated value of a transgene for grain yield, plant height, and anthesis-silking interval in maize. Results showed that the transgene increased yield by 0.2 Mg ha(-1), increased plant height, and reduced anthesis-silking interval. However, there was no genotype interaction observed. This highlights the importance of testing transgene efficacy across a large sample of hybrid pairs to accurately assess its value.

Summary: This study aims to explore the key factors driving food foraging behavior in the U.S. The results indicate that nature and food attitudes predict attitudes toward urban foraging. Leaving food behind is crucial for sustainable foraging practices and promotes fairness in foraging communities.

Summary: The study found that increasing IGF-1 levels had a beneficial effect on body composition but was detrimental to insulin resistance. At the same time, the contribution of the neurogenic vasomotion domain also increased.

Summary: Research in the San Francisco Estuary, CA, USA, has shown that factors such as channel depth, microhabitat, and tides influence fish abundance, while different feeding guilds overlap in space and time. During tidal flooding, fish are predicted to have high gut fullness in subtidal channels, after which they intensively feed throughout the marsh ecosystem.

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.

Summary: Natural selection favors animals that forage more efficiently, such as those that find food faster. However, most studies on foraging behavior and its effects on fitness only measure the effects in the first generation. In this experiment, we artificially selected Drosophila flies that found food faster in a simple maze and measured their fecundity and offspring survivorship. After five generations, the selected flies found food 2.46 times faster than the control flies. Fecundity was higher in the selected flies only in the first generation, and this correlation decreased over generations. These results show that foraging behavior has a strong response to selection in a few generations, but the correlated positive effects on fitness weaken over time.

Summary: Artificial light at night has negative effects on foraging behavior in Asian parti-colored bats, with different spectra of LED lighting affecting the bats' foraging onset, total foraging time, and food consumption differently. The peak wavelength of light is closely related to bats' foraging activity, freezing time, and echolocation vocalizations.

Summary: The study found that the altitude of sleeping sites chosen by Tibetan macaques for acquiring food differed significantly by season, and the sleeping sites were located near foraging patches, indicating the important role of sleeping sites in food resource utilization.
