Summary: Wildlife tourism can impact the behaviors and movements of animals, as shown in our study on yellowtail kingfish. The introduction of food-based attractants increased their activity and burst behaviors, but did not significantly affect their physiological condition. This suggests that the kingfish were able to compensate for the increased energy expenditure through feeding on the bait provided by operators. However, it is important to recognize that the effects of provisioning from wildlife tourism can extend beyond behavior changes and can influence the energetic condition of non-focal animals.

Summary: The research investigated the movement patterns and carrying capacity of white sharks on Guadalupe Island. Different scenarios were calculated to determine the number of cage diving vessels that could operate simultaneously. As the number of cage diving vessels increased, the probability of sighting a white shark decreased.

Summary: This study assessed the response of white sharks to research activities and found that external tagging, biopsies, or deterrent trials do not significantly affect the residency and abundance of white sharks. These changes may be part of natural fluctuations rather than a negative response to the research activities.

Summary: The activity of yellowtail kingfish is strongly influenced by sea surface temperature, hour of day, tide height, and moon fraction. These factors can regulate the behaviors and physiological processes of the species. Additionally, their activity and movement patterns were investigated in a seasonal aggregation in a small temperate estuary.

Summary: Wildlife tourism can contribute to species conservation and regional economies. Sustainable management regulations can minimize detrimental effects on white sharks, as shown by the recovery of white shark residency in Australia's white shark diving industry following the implementation of new regulations in 2012. The adaptive framework used in this industry's management can be applied to other tourism industries.

Summary: The study investigated the movement patterns of lemon sharks using acoustic telemetry along the Ningaloo coast of Australia, revealing longer residency of adults in known nursery areas, with female sharks shifting their core home range further offshore during winter months. Sexual segregation was observed within core areas, with males departing earlier than females. Highly directional and rapid movements correlated with parturition and mating periods were detected, emphasizing the importance of movement data for conservation efforts.

Summary: Quantifying the effect of human-wildlife interactions, particularly those with negative perceptions, can contribute to species conservation. This study examines the shifting perceptions of humans after controlled interactions with white sharks through shark cage diving tourism. The findings demonstrate that such experiences can positively change negative perceptions towards white sharks, and when combined with accurate interpretations of shark behavior and its ecological impact, exposure to sharks can be a valuable tool for promoting public attitudes.

Summary: The COVID-19 restrictions caused a global pause in human activities, providing an opportunity to assess human impact on animal behavior and space use. Variations in restrictions across Australian states have different impacts on human interactions with the marine environment. Through acoustic tracking data analysis and long-term monitoring, researchers can assess how global events like COVID-19 can affect animal movement and distributions.

Summary: This study investigated the dietary methionine and cysteine requirements of Yellowtail Kingfish, finding that cysteine can spare up to 40.4-49.2% of methionine in the total sulfur amino acid requirement. Optimal levels of these amino acids are crucial for growth and feed efficiency in YTK, with sub-optimal levels potentially leading to cataract development.

Summary: A study found that ectothermic marine species exhibit allometric scaling for activity space, although the relationship is weaker compared to terrestrial species. Body mass alone can only explain 35% of the variation, with trophic position and latitude being stronger predictors for marine species. The study highlights the importance of using large-scale animal biotelemetry networks to address evolutionary and ecological questions across different taxa.

Summary: Animal social systems are dynamic and influenced by changes in population demography and resource availability. This study investigated the social organization and connectivity of a wild population of estuarine crocodiles based on a 10-year telemetry data set. Results showed that these crocodiles formed spatially segregated communities along a river and estuary, with social structure and organization being temporally dynamic. The proximity to the mating season and an individual's maturity status influenced the associations among conspecifics.

Summary: In species with costly conflict, individuals use alternative movement tactics to minimize competitive interactions. This study investigated how the behavior of male estuarine crocodiles shifted over an 11-year period in relation to ontogeny, body condition, and physical injuries. Results showed that males sorted into different movement classes, with larger males maintaining confined territories, while smaller males adopted high movement or low movement tactics. Our study provides insights into the mechanisms and costs of movement tactics in wild crocodile populations.

Summary: Wildlife tourism, especially the feeding of animals, can have negative effects on their behavior and physiology. A study in Oslob, Philippines, found that whale sharks showed increased activity and metabolic rates during tourism operations. The research suggests that managers should focus on reducing energy expenditure through changes in operations rather than increasing food quantity.

Summary: Landscapes of fear and energy describe the spatial representation of an animal's perceived risk of predation and the associated foraging costs and energetic cost of moving and foraging, respectively. The integration of fear and energy landscapes can provide a better understanding of predator-prey interactions and their ecological consequences. This paradigm considers both prey and predator landscapes and how changes in energyscapes can affect both foraging behavior and the risk effects on prey. The dynamic nature of energy landscapes adds a spatiotemporal component that can cascade through food webs.
