“…High sampling frequency also allows detecting consistent differences in sustained swimming at various speeds (1-6 body length/s) (Martos-Sitcha et al, 2019b). Moreover, in depth analysis of raw data from exercised fish highlighted that the large amplitude of operculum aperture and body tail movements of European sea bass is part of the adaptive features of this fish species as a fast swimming predator (Ferrer et al, 2020), linked to the natural evolution and behavioral ecology in a predator-prey system (Berger, 2010;de Matos Dias et al, 2018). Besides, selection for growth within the PROGENSA R gilthead sea bream breeding program modified behavioral and physical activity traits, priming growth in genetically fast-growing fish and swimming performance in genetically slow-growing fish (Perera et al, 2021a).…”

Behavioral parameters are reliable and useful operational welfare indicators that yield information on fish health and welfare status in aquaculture. However, aquatic environment is still constraining for some solutions based on underwater cameras or echo sounder transmitters. Thus, the use of bio-loggers internally or externally attached to sentinel fish emerges as a solution for fish welfare monitoring in tanks- and sea cages-rearing systems. This review is focused on the recently developed AEFishBIT, a small and light data storage tag designed to be externally attached to fish operculum for individual and simultaneous monitoring of swimming activity and ventilation rates under steady and unsteady swimming conditions for short-term periods. AEFishBIT is a tri-axial accelerometer with a frequency sampling of 50–100 Hz that is able to provide proxy measurements of physical and metabolic activities validated by video recording, exercise tests in swim tunnel respirometers, and differential operculum and body tail movements across fish species with differences in swimming capabilities. Tagging procedures based on tag piercing and surgery procedures are adapted to species anatomical head and operculum features, which allowed trained operators to quickly complete the tagging procedure with a fast post-tagging recovery of just 2.5–7 h in both salmonid (rainbow trout, Atlantic salmon) and non-salmonid (gilthead sea bream, European sea bass) farmed fish. Dual recorded data are processed by on-board algorithms, providing valuable information on adaptive behavior through the productive cycle with the changing environment and genetics. Such biosensing approach also provides valuable information on social behavior in terms of adaptive capacities or changes in daily or seasonal activity, linking respiratory rates with changes in metabolic rates and energy partitioning between growth and physical activity. At short-term, upcoming improvements in device design and accompanying software are envisaged, including energy-harvesting techniques aimed to prolong the battery life and the addition of a gyroscope for the estimation of the spatial distribution of fish movements. Altogether, the measured features of AEFishBIT will assist researchers, fish farmers and breeders to establish stricter welfare criteria, suitable feeding strategies, and to produce more robust and efficient fish in a changing environment, helping to improve fish management and aquaculture profitability.

“…Non-specialist top predators like cougars, for instance, show cathemeral activity patterns that are suggested as maximizing the efficiency of their foraging behavior in which they use habitats and the circadian cycle in a more generalist manner, and thus the absence of moonlight influence on their nocturnal activities (Harmsen et al, 2011;Soria-Díaz et al, 2016;Pratas-Santiago et al, 2017;de Matos Dias et al, 2018). But Cavalcanti & Gese (2010) found the occurrence of prey selection by jaguars in the Pantanal, indicating predilection for certain species though they are not necessarily the most abundant.…”

“…But Oriol-Cotterill et al (2015) observed that this species transits closer to livestock enclosures with decreasing moonlight. As for cougars (Puma concolor), the species does not seem to be affected by moonlight variation (Harmsen et al, 2011;Soria-Díaz et al, 2016;Pratas-Santiago et al, 2017;de Matos Dias et al, 2018). Finally, the influence of the lunar cycle on jaguars' main prey species is suggested as indirectly affecting jaguar activity (Harmsen et al, 2011;Montalvo et al, 2020).…”

Diante dos níveis crescentes de perda e modificação de habitat, conhecer os fatores ambientais que influenciam o uso do espaço por grandes carnívoros é crucial para esforços de conservação efetivos. Apesar da crescente literatura investigando o efeito da luminosidade da luasobre felídeos topo de cadeia, tais efeitos sobre a onça-pintada (Panthera onca) ainda precisam ser explorados – inclusive no Pantanal brasileiro. O bioma passa, atualmente, por alterações humanas significativas diante da expansão da prática agropecuária, e a caça por retaliação se caracteriza como uma das principais ameaças à persistência das onças no Pantanal. Estudamos a influência da variação da luminosidade noturna no uso do espaço pela onça-pintada no Pantanal Sul. Analisamos dados de localização GPS obtidos via monitoramento de onças com rádio-colaresem campos potencialmente utilizados como pastagens, considerando a distância da florestamais próxima e a luminosidade em cenários de baixa, média e alta intensidade luminosa da lua.Observamos que, embora as onças permaneçam nas imediações das florestas ao longo do ciclolunar, elas adentram mais as pastagens sob média a alta luminosidade da lua. Sugerimos que o usodo espaço pela espécie na área de estudo investigada sustenta a ‘hipótese de risco de predação’(predation risk hypothesis), onde espécies que ocupam níveis tróficos mais altos tendem a ser maisativas sob luminosidade noturna, já que esta possibilita maior sucesso de predação – especialmenteconsiderando que bordas de floresta podem servir como abrigo e favorecer a emboscada do gado.Apesar de não termos focado em sucesso de predação na nossa análise, recomendamos que rebanhos sejam mantidos afastados de bordas de floresta, bem como que sejam implementadas barreiras físicas (ex. cercas) para prevenção de ataques oportunistas das onças aos animais de criação – particularmente em noites mais claras.

“…Daily activity patterns of rabbits show seasonal changes related to environmental conditions such as weather (Villafuerte et al 1993), and rabbits in semi-natural conditions also change their activity patterns gradually throughout the year, depending on sunrise and sunset times (Dı ´ez et al 2007). Rabbits are also known to modify their activity pattern in response to the specialised behaviours of their predators (de Matos-Dias et al 2018;Martı ´n-Dı ´az et al 2018). For instance, rabbits show more diurnal activity when they are under scrub cover because predation risk by carnivore mammals in daytime is lower there than in grassland.…”

Plasticity in daily activity patterns of a key prey species in the Iberian Peninsula to reduce predation risk

ContextSome prey species can shift their daily activity patterns to reduce the risk of encountering predators, and, in turn, predators develop strategies to increase their chances of meeting prey. European rabbit (Oryctolagus cuniculus) is a key species in Iberian Mediterranean ecosystems. It is the main prey for many vertebrate predators. It is also a game species and is often the target of management measures such as translocations. AimsTo test whether rabbits adjust their activity patterns in response to differing predation regimes in a management context. MethodsRabbits were translocated from a donor area, with a high rabbit density, to a release area in central Spain, with a semi-permeable fenced plot and an unfenced plot, which had no rabbits before the translocation. We estimated daily activity patterns and relative abundance index (RAI) for mesocarnivores and rabbits by using camera-traps, and calculated Jacobs selection index (JSI) to classify each species in a diel period. Additionally, we calculated the activity overlap between prey and mesocarnivores in the different areas. Key resultsRabbits were nocturnal in the donor area, where only two mesocarnivore species were detected, red fox (Vulpes vulpes, with a high RAI) and Egyptian mongoose (Herpestes ichneumon, with a low RAI). However, in the unfenced area, where five mesocarnivore species were present, rabbits showed a crepuscular trend with two activity peaks, around sunrise and around sunset. In contrast, rabbits showed a nocturnal activity in the fenced plot, where four mesocarnivore species were detected but where only the Egyptian mongoose (strictly diurnal) had a high RAI value. Conclusions and implicationsThe results suggest that rabbits in the fenced plot adapted their activity to avoid the diurnal mongooses. Conversely, rabbits in unfenced areas showed a trend towards day/twilight activity patterns as an adaptation to a diverse community of mesocarnivores. Rabbits can adapt their daily activity patterns to reduce predation risk depending on the pressure exerted by different predator species, with conservation and management implications. These adaptations would allow higher success of rabbit translocations despite the risk of predation by carnivores and could help in the management design of future translocations of this key species.
