Summary: This study proposed a novel method to accurately track individual trajectories of pigs in group and analyze their behavior characteristics. Experimental results showed that the method based on DLC-KPCA can meet the requirements of identification of piggery area and tracking of piglets' behavior. It is helpful for automatic monitoring of animal behavior and breeding support.

Summary: Many animals rely on memory rather than perception to track the spatiotemporal dynamics of resources within their home range, allowing them to adapt to changes in resource availability. Detailed analysis of animal spatial behavior in the wild can quantify cognitive processes and accurately predict their responses to resource use.

Summary: Research shows significant variation in foraging movements and spatial scales of herbivorous coral reef fishes, both within and across functional groups. This indicates that behavioral differences among superficially similar species may have important implications for competitive interactions and ecosystem functioning.

Summary: The posterior pallial amygdala (PoA), considered a part of the amygdala in birds, plays a vital role in emotion regulation and motor behaviors. This study investigated the structure and function of PoA in pigeons and found that PoAb and PoAc mediate the turning movement and are associated with dopamine receptors.

Summary: Effective collection, recognition, and analysis of sports information is crucial for intelligent sports. This study introduces a novel customizable and flexible triboelectric nanogenerator (CF-TENG) for motion monitoring, which shows highly sensitive responses to joint-bending motions. The proposed system, combined with self-developed algorithms and machine learning, accurately recognizes different motion behaviors and techniques.

Summary: The study found that foraging habitat, sex, and fidelity may impact blood mercury concentrations in western gulls, with gulls primarily foraging in ocean or coastal habitats exhibiting higher mercury concentrations. Fidelity and sex were not significantly associated with gull blood mercury concentrations.

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: The study revealed a significant decline in feral pigeon abundance in open food centers and feeding hotspots after the implementation of a nation-wide Circuit Breaker in Singapore. Changes in food abundance were found to predict changes in feral pigeon populations, with the greatest impact observed in feeding hotspots. Increased abundance of the Javan myna at refuse collection centers during the Circuit Breaker period was also noted.

Summary: Pigeons were used as model animals to study perceptual category learning. By analyzing the pecking responses of the pigeons, researchers gained insight into the categorization strategies of the animals. The study found that pecking location was related to stimulus features and identified different strategies used by pigeons to discriminate between stimulus classes, which remained stable during category transfer but varied between individuals.

Summary: This study utilized NODDI to investigate the association between the microstructural architecture of the amygdala and neuroticism. The findings revealed that lower neurite density in the lateral amygdala nucleus was significantly associated with higher scores in depression, one facet of neuroticism. This suggests that changes in the microstructure of the amygdala could impair its filtering function and potentially lead to neuroticism-related disorders.

Summary: One major survival-related activity of organisms is to seek food in their environment. They exploit rewarding locations and attempt to approach predictive cues of edible items. Foraging is not solely based on reinforcement, as foraging activity may exceed expectations when food is uncertain. These findings have significant implications for understanding animal behavior and survival strategies.

Summary: The exceptional navigational capabilities of migrating birds rely on the perception and integration of various natural orientation cues. A brain area called Cluster N in the forebrain of night-migratory songbirds, connected to the hippocampal formation, plays a role in processing directional navigational information derived from the Earth's magnetic field. Through morphological and histochemical analyses and neuronal tract tracing, researchers have identified the neurochemical characteristics and connections between Cluster N and the hippocampal formation in migratory birds, suggesting the involvement of the densocellular hyperpallium in the transmission of magnetic compass information.

Summary: Birds are important model organisms for studying perceptual categorization and concept formation. The recent focus on avian neuroscience has led to a wealth of new data and a shift in our understanding of sensory and visual structures in avian brains. These discoveries have revealed how categorization occurs in avian brains and have developed a theoretical framework that extends beyond the realm of birds.

Summary: Intelligence is highly heritable and influenced by thousands of alleles. Polygenic scores are useful for studying the genetic effects on intelligence, but little is known about how brain structure and function mediate this relationship. This study found that individuals with higher polygenic scores for intelligence had better cognitive performance, larger brain surface area, and more efficient fiber connectivity. These results provide insights into the neurogenetic basis of intelligence and identify specific brain networks that link genetic predisposition to cognitive abilities.

Summary: The opportunity and information available for securing food resources drive foraging behavior. Inconsistent hole-food pairings and coverings can alter foraging performance, even when food availability is constant. The information about food location may have a more direct impact on foraging behavior than information about food availability.
