Summary: This study investigates the relationship between vocalizations and aggressive behaviors in Mongolian gerbils during same-sex resident-intruder tests. The results show that different sexes and sexual experience affect vocalizations and aggressive responses in encounters. High-frequency vocalizations are associated with non-agonistic interactions, while low-frequency vocalizations are associated with agonistic interactions, predominantly observed in encounters involving multiparous females.

Summary: The research introduces a model to determine the number of honey bee colonies needed for optimal foraging process in a specific location, considering factors such as potential productivity, contamination, and surroundings. The model requires several steps to be completed, ultimately providing the user with the recommended number of colonies to be placed.

Summary: Narwhals have the ability to dive deep but exhibit spinning behavior during foraging, affecting swimming speed and oxygen consumption rate.

Summary: The study found that bats foraging in urban environments were more exploratory, visited more sites per hour, and switched foraging sites more often compared to rural bats, resulting in a more diversified diet. The location of the roost did not determine the foraging ground, with many bats roosting in the countryside but commuting nightly to urban environments for foraging. Bats, unique among small mammals in their ability to move far rapidly, demonstrated how they adapt to environmental changes and exploit the new urban fragmented environment.

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: Foraging decisions of animals are based on a complex process integrating information from external stimuli and internal signals, modulated by individual experience and detection threshold. In social insects, foraging decisions may be influenced by ontogenetic shifts and colony requirements. Short-term changes in foraging preferences depend on the type of resource foraged and social interactions, rather than ontogenetic shifts.

Summary: Sperm whales are an ideal species for studying with passive acoustic technology, and using acoustic line transect data can improve abundance estimation and provide population-level insights into their foraging ecology.

Summary: This study found that sick-like bats exhibited an enhanced immune response and engaged in behaviors that reduce pathogen transmission, such as perching alone and isolating themselves from social clusters. These sickness behaviors help promote recovery of infected individuals while reducing the risk of pathogen transmission.

Summary: The article discusses the methodology and significance of pesticide analysis in bee-related matrices. It presents two different approaches, including the evaluation of monitoring studies conducted from 2011 to 2021 and the revision of current legislations regarding chemicals in apicultural matrices. The findings highlight the need for a clear definition of each apicultural matrix and the presence of widespread agricultural pesticides, as well as the emergence of new chemicals in the field of agriculture and apiculture.

Summary: This study detected mercury levels in the feathers of nocturnal migratory birds in Mount Ailao, Southwest China, and found significant variations among different species. Waterbirds had higher mercury levels, with piscivorous species having significantly higher levels than other foraging types. Foraging guilds and behaviors had significant effects on mercury accumulation. Approximately 7% of birds were at risk of mercury exposure.

Summary: Recent experiments with mice navigating a labyrinth have shown a sharp discontinuity in learning, contradicting the gradual nature of reinforcement learning. By combining biologically plausible reinforcement learning rules with persistent exploration, discontinuous learning is shown to be a common occurrence.

Summary: Interactions between humans and nature often have negative consequences, and behavioral and environmental changes can turn cooperative interactions into conflicts, threatening the survival of both species involved. A study of artisanal fishers and wild dolphins targeting migratory mullets reveals that foraging synchrony is crucial for the success of both predators. The dolphins herd the mullet schools towards the fishers' nets, providing them with more prey, while the fishers' casting behavior must match the dolphins' foraging cues. However, declines in mullet availability are jeopardizing this cooperation and pushing it towards extinction.

Summary: Since the design and commercialization of the Langstroth moveable frame hive in 1854, hive design and beekeeping processes have remained largely unchanged. Bees invest considerable energy to maintain the critical brood nest temperature range, and human honey-harvesting processes can disrupt hive temperature and require additional energy investment from the bees. The thermal properties of honey and wax in the hive may help buffer some of the thermal losses from the hive design, but their removal for harvesting can lead to increased energy expenditure and stress on the bee colony.

Summary: Animals integrate into the wider ecosystem by foraging and behavior, targeting scarce and atypical nutrients according to the compensation hypothesis. This study investigated the variation in resource use by ants across habitat strata and trophic levels in Neotropical biomes. The results showed consistent patterns of sugar and lipid preferences across biomes and trophic levels, indicating sugar limitation in the arboreal stratum and lipid limitation on the ground. However, there was no consistent pattern for amino acid and sodium preferences. Overall, the study suggests strong local niche partitioning of sugar and lipid use and the influence of large-scale processes on amino acid and sodium dynamics.

Summary: There is growing recognition of the impact of social interactions on animal foraging behavior, and ants provide a unique opportunity to study this phenomenon. However, little is known about the influence of queen number on colony-level foraging behavior and performance in polygynous ant species. This study explored the direct effects of queen number on protein-carbohydrate regulation, food collection, survival, and brood production in two polygynous ant species, and found that queen number had significant impact on these factors. The results highlight the importance of queen presence in shaping colony-level foraging and performance, with interspecific variation being influenced by differences in life history traits.
