“…On the other hand, the acclimatization was important to monitor the adaptation of the agoutis to radio collars [16]. The weight gain during the acclimatization was also important because released animals, especially the ones coming from captivity, may find it difficult to get food right after release and die of malnutrition (e.g.…”

“…Acclimatization is important to familiarize the animals with local conditions, to allow them to gain weight, and to perform skill training (e.g. [16][17][18][19][20][21]). It also allows monitoring of the individuals' adaptation to the tracking equipment (in this study, a modified TXE-311C collar with activity sensor; Telenax®, Playa del Carmen, Mexico; see [16]).…”

Reintroduction is an increasingly important tool to restore local extinctions and ecological interactions. Evaluating the success of reintroduction projects allows conservationists to learn from previous experience. Here we report on the reintroduction of agoutis, Dasyprocta leporina, to a Brazilian Atlantic Forest reserve in order to (1) determine the short-term status of the reintroduction; (2) describe and evaluate the management procedures that contributed to reintroduction success; and (3) identify the fruits and seeds consumed and buried by the agoutis, as an indication of their role in restoring ecological processes. We captured and tagged 21 adult individuals from a semi-captive population and reintroduced four males and seven females. One male died and almost all individuals lost weight (range=0-620 g; n=11) during quarantine (median=133 days; range=67-243 days; n=20). Six males and three females died, but the others gained weight during acclimatization (range=150-260 g; n=5). Individuals abandoned the food supplement up to 87 days after release, establishing home-ranges at least three times larger than in natural populations of agoutis. The estimated annual survival rate was 0.83, and 10 nature-born cubs were observed. The reintroduction was considered successful in the short-term. Among the main recommendations for future reintroductions, we suggest the reduction of quarantine and the maintenance of acclimatization periods, with structural improvements for both. Agoutis were seen eating fruits and seeds of 10 species and burying seeds of three of them. The buried seeds are from zoochoric large-seeded trees, thus enhancing recruitment in a disperser-impoverished forest.Keywords: Dasyprocta leporina, frugivory, radiotracking, reintroduction, spatial patterns. Resumo A reintrodução é uma ferramenta cada vez mais importante para restaurar extinções locais e interações ecológicas. Avaliar o sucesso de projetos de reintrodução permite que conservacionistas aprendam com experiências prévias. Aqui nós reportamos a reintrodução de cutias Dasyprocta leporina em uma reserva da Mata Atlântica brasileira, objetivando (1) determinar o status da reintrodução em curto prazo, (2) descrever e avaliar os procedimentos de manejo que contribuíram para o processo de reintrodução e (3) identificar os frutos e sementes consumidos e enterrados pelas cutias, como um indicativo do seu papel na restauração de processos ecológicos. Nós capturamos e marcamos 21 indivíduos adultos originários de uma população semicativa e reintroduzimos quatro machos e sete fêmeas. Um macho morreu e quase todos perderam peso (variação=0-620 g, n=11) durante a quarentena (mediana=133 dias, variação=67-243 dias, n=20). Seis machos e três fêmeas morreram, mas os outros ganharam peso durante a aclimatação (variação=150-260 g; n=5). Os indivíduos abandonaram a suplementação alimentar em até 87 dias depois da soltura, estabelecendo áreas de vida pelo menos três vezes maiores do que as encontradas para populações naturais de cutias. A taxa de sobr...

“…Determining a good fit is vital. Even if rubbing does not result in damage to the skin itself in relatively dry environments (as observed in Cunningham et al In Review), regions experiencing higher precipitation may engender the growth of microorganisms between the neck and collar, potentially increasing the risk of infection if the skin were to be ruptured by wear from the collar or from scratching by the animal [20, 74]. These symptoms, caused by biting flies in reintroduced oryx at our study site in Chad in 2018, were exacerbated by the collar.…”

“…Our study illustrates that effects from GPS collar fitting were short-term and provided no foundation for welfare concerns. Due to the enduring question of if and how monitoring devices impact wildlife [37,74,77], we highly encourage researchers involved with wildlife tracking programs to evaluate the effects that monitoring devices have on the survival and fitness of the individuals they aim to save.…”

28GPS collars have revolutionized the field of animal ecology, providing detailed information on 29 animal movement and the habitats necessary for species survival. GPS collars also have the 30 potential to cause adverse effects ranging from mild irritation to severe tissue damage, reduced 31 fitness, and death. The impact of GPS collars on the behavior, stress, or activity, however, have 32 rarely been tested on study species prior to release. The objective of our study was to provide a 33 comprehensive assessment of the short-term effects of GPS collars fitted on scimitar-horned oryx 34 (Oryx dammah), an extinct-in-the-wild antelope once widely distributed across Sahelian 35 grasslands in North Africa. We conducted behavioral observations, assessed fecal glucocorticoid 36 metabolites (FGM), and evaluated high-resolution data from tri-axial accelerometers. Using a 37 series of non-standard regression models, we illustrate clear but short-term effects to animals 38 fitted with GPS collars. Behavioral observations highlighted a significant increase in the amount 39 of headshaking from pre-treatment levels, returning below baseline levels during the post-40 treatment period (>3 days post-collaring). Similarly, FGM concentrations (i.e., stress hormones) 41 increased after GPS collars were fitted on animals but returned to pre-collaring levels within 5 42 days of collaring. Lastly, tri-axial accelerometers, collecting data at eight positions per second, 43 indicated a > 480 percent increase in the amount of hourly headshaking immediately after 44 collaring. This post-collaring increase in headshaking was estimated to decline in magnitude 45 within 4 hours after GPS collar fitting. These effects constitute a handling and/or habituation 46 response (model dependent), with animals showing short-term responses in activity, behavior, 47 and stress that dissipated within several hours to several days of being fitted with GPS collars. 48Importantly, none of our analyses indicated any long-term effects that would have more pressing 49 animal welfare concerns. 3 | Stabach et al. 3 50 51 52 Global Positioning System (GPS) devices have revolutionized the field of animal ecology [1-3], 53 providing detailed information about how animals move and utilize space across diverse and 54 often rapidly changing landscapes [e.g., 4-7]. A variety of taxa can now be monitored, ranging 55 in size from pint-sized ovenbirds (Seiurus aurocapilla; [8]) to multi-ton elephants (Loxodonta 56 africana; e.g., [9]). In some instances, animals are now being monitored over their entire 57 lifespans [10], a result of technological innovations (e.g., solar rechargeable batteries) or re-58 tagging efforts, and at temporal resolutions (minutes to seconds) that would have been 59 unimaginable just a few decades ago. 60Since the inception of animal tracking, scientists have recognized the ethical concerns of 61 fitting animals with tracking devices, providing general guidelines (e.g., devices should weigh 62 <5% of total animal body weight) and in most ca...

This article introduces a new class of socio-technical systems, interspecies information systems (IIS) by describing several examples of these systems emerging through the use of commercially available data-driven animal-centered technology. When animal-centered technology, such as pet wearables, cow health monitoring, or even wildlife drones captures animal data and inform humans of actions to take towards animals, interspecies information systems emerge. I discuss the importance of understanding them as information systems rather than isolated technology or technology-mediated interactions, and propose a conceptual model capturing the key components and information flow of a general interspecies information system. I conclude by proposing multiple practical challenges that are faced in the successful design, engineering and use of any IIS where animal data informs human actions.
