Summary: We have found evidence of scent marking in the large-antlered muntjac (Muntiacus vuquangensis). This behavior is likely important for individual recognition and may communicate the cost of aggressive interactions between rival males, as well as be a mechanism for mate assessment among females.

Summary: Scent-marking through odours from excreta and glandular secretions is common in mammals. We studied the diademed sifaka lemurs in Madagascar and found that they use a combination of glandular secretions and excreta for marking, with dominant individuals using glandular secretions more frequently. Males exhibited more complex marking sequences than females, but the height and tree part targeted for marking did not differ significantly among age and sex groups.

Summary: Primates are traditionally thought to rely more on hearing and vision than on smell. However, lemurs, particularly crowned lemurs, exhibit complex olfactory behaviors including conspicuous scent-marking. This study revealed sexual dimorphism in crowned lemur scent-marking behavior, with males displaying defensive territorial functions through head and wrist marking, and socio-sexual communication through ano-genital marking, while females may be involved in resource defense through ano-genital marking.

Summary: Chemical communication is essential for brown bears, as they utilize glands and pedal marks to convey information at specific marking sites. Gender and age play different roles in this process, with adult males being the primary performers of marking behaviors. Behavior associations and repeated marking contribute to the establishment of long-term communication hubs at marking sites.

Summary: This study provides a quantitative assessment of scent-marking behaviors by African wild dogs at shared marking sites visited by multiple resident neighboring packs. The findings suggest that these marking sites serve as a means of communication about residence and potentially reproductive status.

Summary: Intraspecific interactions shape animal social networks and regulate population dynamics. Species with solitary life histories rely on communication cues, especially olfaction for many terrestrial mammals. However, little is known about how species with solitary life histories structure and maintain sociospatial systems.

Summary: The study found that some populations of striped skunks do engage in scent-marking behaviors, indicating communication through this method. By using camera traps, researchers can discover previously undocumented animal behaviors.

Summary: This study chemically characterized the marking fluid of male cheetahs and aimed to identify potential pheromones related to sexual behavior/attraction in this species. The results supported the hypothesis of differences in volatile organic chemicals between male cheetahs, while also highlighting the influence of diet and age. The study emphasizes the importance of scent in cheetah reproduction and the need for further research on strategies to improve captive breeding.

Summary: Understanding the use of space by endangered African wild dogs is crucial for their conservation. The use of scent-marking is likely a key mechanism for their mutual use of space. A recent discovery showed that African wild dog packs repeatedly shared a scent-marking latrine, demonstrating their inter-pack communication.

Summary: Behavioral strategies in scent communication reflect animals' adaptive capacity. Giant pandas rely heavily on scent communication, with preferences for certain tree species, elevations, aspects, and times of day for marking. Frequency of scent communication peaks in October, December, and March, with higher AGS markings during mating season.

Summary: Male meadow voles rely on olfactory communication for finding mating opportunities during the breeding season. The age of a rival male did not affect male scent marking behavior or preference for females, indicating that individual rival odors may not pose a strong enough competitive threat. The study suggests that scent marks could provide valuable information about female quality to male voles.

Summary: We propose the task of local state marking (LSM), where randomly chosen multipartite quantum states are distributed among separated parties, and the identities of the states are to be marked through local quantum operations and classical communication. We show that LSM is different from local state distinguishability (LSD) and investigate the use of entanglement in assisting the marking of otherwise unmarkable states.

Summary: Recently, optical camera communication (OCC) has emerged as a promising solution for future intelligent transportation systems due to its secure, mobile support, and excellent bit-error rate; however, its data rate lags behind RF-based systems, leading to reliability issues in fast-changing channels. This review article examines the applications of OCC in vehicle-to-vehicle and vehicle-to-infrastructure networks, discussing standardization, principles, channel characteristics, and challenges.

Summary: Habitat loss and fragmentation pose significant threats to carnivores worldwide, particularly to large predators. Through the use of microsatellite markers and field data, this study found that jaguars in the Pantanal represent a panmictic population with some local differentiation, and that the Paraguay River plays a crucial role in promoting gene flow among populations. Genetic evidence of female philopatry and male-biased dispersal in jaguars was reported for the first time, along with the first timeline pedigree and direct estimate of the species' generation time, contributing to more realistic assessments of jaguar population dynamics and long-term genetic viability for improved conservation strategies.
