Summary: Dogs prioritize nutritionally valuable food while foraging alone, but also scavenge less valuable food. In the presence of intra-group competition, dogs transition from random to systematic foraging and eat first before sampling in groups. They adjust their behavior based on the patch quality and show reduced individual vigilance. These decisions support the optimal foraging theory and highlight the cognitive abilities and adaptability of dogs, which may have influenced domestication.

Summary: The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) launched on May 22, 2018, carrying the Laser Ranging Interferometer (LRI) for measuring inter-satellite distance with nanometer precision. An analysis was conducted on the inter-satellite pointing angles derived from LRI for 2019 and 2020, comparing them with data from GRACE-FO SCA1B, and investigating the correlations between attitude data and spacecraft temperature variations.

Summary: Free-ranging dogs have a negative impact on wildlife conservation, and tourists may play a role in facilitating their access to protected areas. This study in the Cape Horn Biosphere Reserve in Chile found that free-ranging dogs followed tourists into these areas, even on multi-day trips. The engagement of the tourism sector in wildlife conservation, including promoting responsible pet ownership and confinement of dogs, is crucial.

Summary: Changes in the immediate environment, whether natural or anthropogenic, drive organisms to develop adaptive strategies. Human overcrowding particularly affects urban living animals, like free-ranging dogs, causing changes in behavior and spatial distribution. A sudden increase in human footfall can lead to decreased abundance and altered behavior in urban-adapted animals.

Summary: This study assessed the effectiveness of a mass dog vaccination program in Bengaluru, India. Testing blood and serum samples from vaccinated stray dogs, the study found that 71% and 87% of the samples had adequate levels of antibodies for protection against rabies as determined by RFFIT and iELISA tests respectively. The quantitative iELISA was found to be useful for large-scale seromonitoring of the vaccination program.

Summary: Through reconstructing the genetic pedigree and assessing kinship patterns, it was found that free-ranging dogs exhibit a polygynandrous mating system with a network of kinship relationships across packs. While retaining some common reproductive patterns with wolves, such as repeated mating of the same pairs and adult offspring staying within packs, the shift in ecological niche from apex predator to human commensal likely influenced this behavior.

Summary: Olfactory cues are important in human life, as humans can recognize family members and friends by their odors. Dog owners are capable of identifying their dogs by smell, with male owners outperforming females. Additionally, dog owners who keep their dogs outdoors had a higher success rate in identification, and younger dog owners tended to be more successful in identifying their dogs.

Summary: Dog meat consumption is common in Nigeria, but the presence of canine viruses in trade dogs has not been explored. This study identified the molecular evidence of canine parvovirus, canine distemper virus, and canine circovirus in trade dogs in Nigeria. These findings highlight the potential role of dog trade in spreading highly pathogenic canine viruses and the need for further surveys to determine the virus burden in these animals.

Summary: Free-ranging owned dogs are a conservation concern worldwide, but research on their movement patterns has only recently started to increase. This study used GPS devices to track the movements of village and rural dogs on a sub-Antarctic island in Chile. The results showed that the dogs had a high degree of spatial and temporal variability in their movements.

Summary: The study found that 39% of free-ranging village dogs in southern Chile had over 5% of their locations in natural areas, with only three dogs going on overnight excursions. Dogs tended to have larger home ranges, move farther away from home or access nature more intensively when they exhibited more exploration, more intensive greetings to their owners, and more passive behaviors in the presence of their owners.

Summary: Free-ranging domestic dogs pose a significant threat to wildlife species in Iran through predation, with attacks mainly targeting carnivores and Artiodactyla. The majority of attacks occur within or near protected areas, highlighting the urgent need for better management and policy guidance to protect threatened species.

Summary: Allomaternal care, including behaviors such as babysitting and nursing, in free-ranging domestic dogs is observed among matrilineal relatives who help each other with pup rearing. The frequency and duration of caregiving activities differ between biological mothers and allomothers, with allonursing being more common among older bitches. Possible reasons for allonursing include excess milk, benefits to pups, insufficient milk from biological mothers, and promoting affiliative relationships among group members. This study supports kin selection theory, especially as allonursing is prevalent in other gregarious wild canids.

Summary: The study investigated the activity patterns of three squirrel species by using camera trapping. It was found that the squirrels descended to the ground during the day and avoided temporal overlap with wild predators. However, they had high temporal overlap with domestic dogs, which could pose a conservation problem for these species.

Summary: The study reveals behavioral variations in the degree of sociability of free-ranging dogs in urban environments, with dogs in high human flux zones showing higher sociability compared to dogs in low and intermediate human flux zones. High human flux zone dogs were initially reluctant to approach but showed increased sociability when food was provided, while low human flux zone dogs were the least sociable even with food rewards having minimal impact on them.

Summary: The study on free-ranging dogs in West Bengal, India, reveals that these dogs are generalists in their habit, staying active when humans are active. Their activity levels are significantly influenced by age and time of the day. This study provides a detailed ethogram of free-ranging dogs, which could further contribute to the understanding of their eco-ethology.

Summary: The study reveals that frequency-rank data of animal behaviors in nature follow scale-invariant power law behavior at the population level, showing consistent patterns even with variations in location and season. Robust self-similarity patterns are observed at different scales, indicating the possibility of designing predictive models of behavior and exploring syntax in a species' overall behavioral repertoire.

Dogs who received petting followed the pointing cues regardless of their informative or deceptive nature, while dogs who did not receive petting discriminated between informative and deceptive cues during pointing.

Summary: Time-activity budgets are important indicators of an animal's energy intake and expenditure, and understanding individual variations in these budgets can provide valuable insights into a species' lifestyle. This study examines how animal personality traits can influence individual time-activity budgets in lion-tailed macaques. The findings suggest that personality traits such as persistence and sociability can predict the time spent on different behaviors, highlighting the importance of considering personality in ecological research.
