“…Current technology makes it difficult to measure the presence of a known particulate in the air. The literature surveyed suggests that most studies on elephant olfaction either expose elephants to a known chemical, assessing their reactions, or present the same scenario to elephants both with and without the chemical [162,163,165]. This means that in order to conduct this work, the researcher must first identify a particular chemical of interest, and then test it, which is a very costly method of research.…”

“…Olfaction, or the sense of smell, plays a critical role in the lives of elephants as well as in conservation efforts. Elephants have an extraordinary sense of smell, which they rely on for various purposes, such as foraging, locating water sources [162], identifying herd members [163], communicating with other elephants [164] and navigation [165]. The elephant’s olfactory system is highly developed, featuring a large number of olfactory receptor genes and a sophisticated vomeronasal organ [166,167].…”

Artificial intelligence (AI) and machine learning (ML) present revolutionary opportunities to enhance our understanding of animal behaviour and conservation strategies. Using elephants, a crucial species in Africa and Asia’s protected areas, as our focal point, we delve into the role of AI and ML in their conservation. Given the increasing amounts of data gathered from a variety of sensors like cameras, microphones, geophones, drones and satellites, the challenge lies in managing and interpreting this vast data. New AI and ML techniques offer solutions to streamline this process, helping us extract vital information that might otherwise be overlooked. This paper focuses on the different AI-driven monitoring methods and their potential for improving elephant conservation. Collaborative efforts between AI experts and ecological researchers are essential in leveraging these innovative technologies for enhanced wildlife conservation, setting a precedent for numerous other species.

“…Male Asian elephants exhibit greater interest in dung from pre-(follicular) compared to post-ovulatory (luteal) phase females [95]. African elephants use olfactory cues (e.g., urine-soaked earth) along pathways and around waterholes potentially to determine the identity and location of conspecifics [86,[96][97][98]. Other secretions that potentially release pheromones for intraspecific signaling include saliva, mucus, and fluid from the ears and interdigital glands [24,99].…”

Chemical signals are the oldest and most ubiquitous means of mediating intra- and interspecific interactions. The three extant species of elephants, the Asian elephant and the two African species, savanna and forest share sociobiological patterns in which chemical signals play a vital role. Elephants emit secretions and excretions and display behaviors that reveal the importance of odors in their interactions. In this review, we begin with a brief introduction of research in elephant chemical ecology leading up to the 21st century, and then we summarize the body of work that has built upon it and occurred in the last c. 20 years. The 21st century has expanded our understanding on elephant chemical ecology, revealing their use of odors to detect potential threats and make dietary choices. Furthermore, complementary in situ and ex situ studies have allowed the careful observations of captive elephants to be extended to fieldwork involving their wild counterparts. While important advances have been made in the 21st century, further work should investigate the roles of chemical signaling in elephants and how these signals interact with other sensory modalities. All three elephant species are threatened with extinction, and we suggest that chemical ecology can be applied for targeted conservation efforts.

Plantation Worlds

Relations between earth and life, and how these are politically molten, have witnessed a renewed attention with debates around the Anthropocene. This chapter argues that such transformations are not the outcome of the agency of “mankind” or humanity as a whole. Rather, they are the product of coercive cartographies and pathways of power. This argument, informing the wider scope of this book, is fleshed out through three interventions. By animating archives, the chapter shows how colonial violence and plantation logics, in their quest to produce cheap natures, created new arrangements of human and other-than-human life. By animating landscape, it unsettles humanist readings of environmental transformations. By shifting from a politics of representation to one of dwelling, the chapter foregrounds how people and elephants make worlds along and against the grain of coercive designs. Resituating anthropogenic fauna as postcolonial, it provides openings for specifying ecologies of the present: as a Plantationocene.
