Summary: Herbivores face conflicting demands of feeding and avoiding predation, leading to adjustments in foraging strategies such as vigilance behavior and time allocation in feeding areas. Behavioral and attentional priorities are adjusted in response to variations in food availability and predation risk, influencing the shape of the functional response in terms of intake rate and total food consumed.

Summary: Research on the feeding habits and foraging strategies of giant pandas is important for understanding their population ecology. In the Meigu Dafengding Nature Reserve in the Liangshan mountains, wild giant pandas primarily feed on Yushania maculata and Yushania ailuropodina, and prefer foraging patches with gentle slopes and closer proximity to water sources. The findings of this study can provide a scientific basis for the conservation and management of wild giant panda habitats in different mountain regions.

Summary: This study investigated the effects of different finishing systems and growth rates on the meat metabolome of animals. The results revealed distinct differences in meat metabolism caused by growth rate, particularly in energy metabolism and associated pathways. Additionally, the feeding system was found to alter protein and lipid metabolism.

Summary: This article introduces a novel multi-point differential feeding technique for the design of filtering patch antennas with a wide upper stopband. The proposed method effectively excites the desired fundamental mode and eliminates high-order modes by selecting suitable feeding positions, resulting in improved filtering performance.

Summary: Intraspecific feeding choices play a significant role in herbivore foraging decisions. Herbivores respond to plant quality variation based on nutritional and energetic demands. Plant growing conditions can influence herbivore body conditions, but the interactions between plants and herbivores are also mediated by energetic statistics.

Summary: Models of trophic needs and impacts of mobile predators often overlook the interactions between prey dispersion and profitable foraging thresholds. This can lead to underestimated biomass of supported predators and their impacts on food web components. Accounting for prey patch structure and profitability thresholds is crucial when estimating the functional availability of prey for endothermic predators.

Summary: We investigated the foraging strategy of the jumbo squid Dosidicus gigas when energy demands for growth and reproduction increase as maturation. Results indicated that mature female D. gigas differ spatially in energy accumulation and feeding habits, but have a foraging strategy that increases the intake of higher trophic prey items to meet energy demands.

Summary: This study investigated the costs and benefits of group living in wintering foraging Greater White-fronted Geese. The researchers measured the individual's spatial position within a flock as the distance to the flock edge and analyzed the effects of this distance on antipredation cost and foraging benefit. The study found that the distance to the edge significantly affected the individual's vigilance time, foraging time, and intake rate. The critical distance that predicted behavioral changes was around 2.5 m, with individuals closer to the edge being more vigilant and having less efficient foraging than more central individuals. The researchers also proposed a dichotomous classification scheme that can better detect the behavioral differences between central and peripheral individuals compared to the traditional minimum convex polygon method.

Summary: This study assessed the turbidity effects of Palm Oil Mill Effluent (POME) on the feeding ability of male siamese fighting fish. The results showed that the feeding rate, aggressive behavior, and foraging area of the fish significantly decreased with increasing turbidity levels of POME. Additionally, the time to capture first prey significantly increased. The study also revealed retinal degenerations in siamese fighting fish exposed to high-level turbidity of POME.

Summary: The experiment results showed that using the slow anaerobic feeding strategy can form a stable aerobic granular sludge, while high OLR can form granules quickly but may lead to instabilities. Research recommends forming granules quickly with high OLR and then reducing the OLR to maintain stability.

Summary: This study investigated the antipredator responses of two herbivore species and one mesopredator to predation risk imposed by lynx and wolf. The results showed that roe deer avoided lynx urine, hares did not significantly avoid predator urine, and red foxes were attracted to lynx urine in sympatric situations. These findings generally supported the hypothesis of predator avoidance by herbivores and attraction combined with increased vigilance of mesopredators.

Summary: Groove-section profiled ring rolling (GSPRR) is a challenging forming process. In this study, an advanced feeding strategy driven by staged growth velocity is proposed for GSPRR to establish a stable rolling process and improve ring quality. Mathematical models and simulations are used to demonstrate the effectiveness of the new feeding strategy. It is recommended to choose intermediate values for the growth velocities to achieve better rolling stability and ring geometry accuracy.

Summary: This study examines the direct and indirect effects of habitat loss and vegetation density on small-mammal species diversity in South American savannas. The results show that landscape-level metrics play a more important role in explaining species richness, with a strong association between local and regional landscapes. Additionally, a combination of landscape-level and patch-level metrics is crucial in determining small-mammal species composition in savanna patches.

Summary: Analyzing multispecies surveys conducted in Central Africa's seven main savanna national parks between 1960 and 2017, it was found that populations of wild large herbivores declined, livestock numbers increased, and tourism industry collapsed. To address this issue, it is proposed to strategically retreat and focus resources on smaller areas to conserve wildlife in the Central African savannas.

Summary: This study analyzed changes in boma distribution and density in the Laikipia-Samburu ecosystem of northern Kenya from 2011 to 2019 using satellite imagery, and examined the relationship between elephant movement and bomas using GPS data. The results showed that elephants adjusted their behavior to avoid human activity around bomas, particularly during the dry season. Understanding the consequences of these behavioral adjustments is critical for the long-term population viability of elephants.

Summary: Biologging refers to the use of animal-borne recording devices to study wildlife behavior, and the processing of the large amounts of audio data collected from these devices is a challenge. This paper explores different approaches, including traditional compression, deep-learning classification at the edge, and embedded pre-processing, to reduce the stored data in terms of dimension while maintaining classification accuracy. The results show that ADPCM encoding can save energy compared to uncompressed audio, and performing inline data-preparation can significantly reduce stored data with acceptable classification accuracy.

Summary: This study provides the first spatially explicit population density estimates for spotted hyaena in Tanzania, and suggests that their density is influenced by prey availability and protection. Additionally, the study reveals a positive correlation between spotted hyaena densities and densities of lion and leopard, indicating that human disturbance and prey availability have a greater impact on large carnivore densities in the studied system.

Summary: Tropical ecosystems, which harbor the highest biodiversity on the planet, are facing significant land conversion for agriculture. Previous studies have focused on the impacts of forest cover loss on tropical biodiversity, neglecting the role of habitats surrounding forest fragments. This study found that the composition and abundance of small-mammal communities are closely related to the land cover surrounding forest fragments, emphasizing the importance of maintaining native vegetation in human-modified landscapes.

Summary: This study investigates people's attitudes towards using Barn Owls for rodent control and finds that gender and parental influence play a significant role in shaping the community's perceptions of owls. The distance of the homestead from a protected area and the village of origin also influence people's views on owls.
