While the existence of human–animal relationships dates back thousands of years, the effects of these bonds on animal well-being have only recently been examined in detail. The existing literature demonstrates that factors such as familiar human caregivers and persistent, predictable care may, for example, lower an animal’s fear response and improve overall welfare. The goal of the present study was to analyse how a range of variables, including age, sex, animal species, and previous bonds with a pet could influence the development of human–animal bonds between caregivers and animals at six affiliated zoological facilities. The present study is a survey of 201 animal caregivers focusing on their perception of the bonds shared between themselves and an animal with which they work and any experience with bonds they have with a companion animal at home. All respondents, regardless of the existence of a human–animal bond, also indicated their level of agreement with a series of general statements about human–animal relationships and their effects on animal management and welfare. The present study demonstrates that the type of animal species has a significant effect on the development of bonds between animals and their human caregivers, with a greater percentage of bonds developed between people and other mammalian species, and the smaller percentage of bonds between people and fish or reptiles. Personal identifiers, such as age, sex, or the number of years in the profession, did not have any significant correlation to bond development. In addition, having pets was also not a predictor of caregiver–animal bonds, though previous experiences with animal bonds did indicate a tendency to develop a bond. Overall, surveyed caregivers agreed with positive statements about human–animal relationships and their role in promoting better welfare for animals. Understanding the bonds shared by animal caregivers and the animals for which they are responsible is essential to fostering workplaces that consider the importance of the relationship between humans and animals, and the tangible benefits a positively perceived bond can have for both.

Arabian Sea humpback whales (Megaptera novaeangliae), listed as “Endangered” on the International Union for Conservation of Nature’s Red List, remain resident throughout the year in the waters of the Arabian Sea and constitute a genetically isolated population. In the eastern Arabian Sea, information on humpback whales off the Indian coast has largely been limited to stranding records, local ecological knowledge, and opportunistic visual sighting data. These data, along with information from a long-term study off Oman, suggest that humpback whales migrate across the Arabian Sea into Indian territorial waters from October to March. To study the presence of Arabian Sea humpback whales in Indian waters more comprehensively, passive acoustic monitoring (PAM) was initiated along the west coast of India in 2019. Male humpback whales produce complex songs with a stereotyped structure; these songs are shared within a population, and song patterns are known to evolve progressively over time. In this article, a structural analysis of humpback whale song recorded over four days off the coast of Netrani Island, Karnataka, India, in December 2019 is presented. Time-frequency features of 2,641 individual call units were analysed. Call units had a fundamental frequency bandwidth ranging from 149.98 to 541.65 Hz, with a duration ranging from 1.19 to 5.5 s. The call units were used to identify phrases and themes required to construct the structure of the song, which can potentially help identify the population to which singing individuals belong. This study indicates the need for a long-term PAM program across the Arabian Sea to compare whale songs across the region. Simultaneous recordings over multiple seasons will best assess population connectivity, seasonal occurrence, and movement patterns within and between populations across the Arabian Sea and the Indian Ocean.
阿拉伯海座头鲸（Megaptera novaeangliae）被国际自然保护联盟（International Union for Conservation of Nature）的红色名录列为“濒危”物种，常年居住在阿拉伯海水域，是一个基因孤立的种群。在阿拉伯海东部，关于印度海岸座头鲸的信息在很大程度上仅限于搁浅记录、当地生态知识和机会视觉观测数据。这些数据，以及阿曼海域一项长期研究的信息表明，座头鲸在10月至3月期间穿越阿拉伯海迁移到印度领海。为了更全面地研究阿拉伯海座头鲸在印度水域的存在，2019年在印度西海岸启动了被动声学监测（PAM）。雄性座头鲸会发出结构刻板的复杂歌声；这些歌曲在一个群体中是共享的，并且已知歌曲模式会随着时间的推移而逐渐演变。本文对2019年12月在印度卡纳塔克邦Netrani岛海岸四天内记录的座头鲸歌声进行了结构分析。分析了2641个单独呼叫单元的时频特征。呼叫单元的基频带宽在149.98到541.65赫兹之间，持续时间在1.19到5.5秒之间。呼叫单元用于识别构建歌曲结构所需的短语和主题，这可能有助于识别唱歌个体所属的群体。这项研究表明，需要在阿拉伯海开展一项长期的PAM计划，以比较该地区的鲸鱼歌声。多个季节的同时记录将最好地评估阿拉伯海和印度洋人口的连通性、季节性发生以及人口内部和之间的流动模式。

Latrines are important sites for intraspecific olfactory communication in mammals, especially for solitary or widely distributed species. Communal latrines give visitors access to information about other visitors, notably conspecific chemical cues, even in their absence. Chemical communication has evolved to allow information transfer among individuals that, due to other ecological constraints, do not co-occur in time. Latrines can be difficult to find and monitor but provide useful information about the behavioral ecology of otters. The aim of this study was to describe the behaviors of Neotropical otters (Lontra longicaudis, Olfers, 1818) in two communal latrines using video-camera traps. A total of 1,651 one-minute footage of otters visiting the latrines were used to elaborate an ethogram that included individuals (1) passing by, (2) rubbing, (3) scent marking, (4) scratching, (5) in vigilance, (6) smelling, (7) defecating, (8) urinating, (9) digging, (10) self-grooming, and (11) interacting with others. These results suggest that latrines are not only used by Neotropical otters to deposit feces and urine but that they also play a role in intraspecific communication. We suggest that L. longicaudis latrines function as information centers where individuals can monitor the location and activities of potential sexual partners and/or competitors.

Affiliative behavior in social animals may have several functions such as maintaining social bonds, reducing tensions, or restoring relationships. Common bottlenose dolphins (Tursiops truncatus) engage in several affiliative behaviors, including parallel swimming, contact swimming, and flipper rubbing. Dolphins affiliate with former opponents after aggression, suggesting that this is a function of tension reduction. This study investigated how affiliative behaviors occur after aggression. Parallel swimming occurred more frequently than expected after aggression, while contact swimming and flipper rubbing occurred less frequently than expected. Parallel swimming and contact swimming occurred immediately after aggression; in contrast, flipper rubbing tended to occur more than one minute after aggression. These results suggest that common bottlenose dolphins engage in parallel swimming and contact swimming when social tension increases. The function may differ among these affiliative behaviors, and dolphins may engage in specific affiliations after aggression.

The coastal bottlenose dolphin is well studied throughout its natural range, though most research focuses on wide, well-protected habitats such as bays and estuaries rather than on narrow coastal sand banks. This study identifies a residential group of coastal bottlenose dolphins utilizing the northwestern Atlantic waters off the coast of Palm Beach County, Florida. From 2014 to 2020, 313 boat surveys were conducted, and 585 individual dolphins were identified using photo-identification. Using seasonal and annual resighting ratios, 24 dolphins were considered full-time residents, 66 dolphins were considered part-time residents, and 478 dolphins were transient. The presence of individuals with high site fidelity indicates that the region is used as a permanent habitat for some individuals, while the presence of transient animals may indicate a possible bridge between populations living to the north and south of the region.
