“…Novo Airão is a small town situated 183 km by land from Manaus and represents one of the main destinations for local inhabitants and tourists alike. The Anavilhanas National Park has approximately 350,000 hectares of area and about 400 islands, making it the second largest river archipelago in the world [ 10 , 13 , 14 ]. Its aquatic environment is formed by black waters of the Negro River, which are poor in nutrients and have high concentrations of organic compounds, resulting an acidic pH 4.6–4.8 while the dissolved oxygen level was 5.0–5.5 mg/L [ 15 , 16 ].…”

Amazon River dolphins are an important flagship species in the Anavilhanas National Park, Brazil, where they interact with visitors. This study aimed to quantify and identify fungi isolated from dolphin skin and oral samples and their surrounding environment in this unique ecosystem. Samples were collected from three dolphins and water samples from Flutuante dos Botos and the Novo Airão city harbor. Fungi were isolated using culture media and identified through micromorphology assays and ITS region sequencing. Oral swab samples resulted in culture of Trichosporon montevideense and Exophiala dermatitidis. Skin samples from one dolphin revealed Toxicocladosporium irritans and Diaporthe lithocarpus. Water samples exhibited higher fungal counts and diversity, with Rhodotorula mucilaginosa, Exophiala dermatitidis, Penicillium citrinum, Fomitopsis meliae, and Nectria pseudotrichia identified at the collection site and Candida spencermartinsiae and Penicillium chermesinum at the city harbor. This study provides important insights into the fungal diversity associated with Amazon River dolphins and their environment, enhancing our understanding of the public health and ecological dynamics in the Anavilhanas National Park.

“…On the other hand, Vidal et al [57] noted that sightings of botos occurred more often in the morning hours, particularly between 08:31-11:30 h, and then spiking again in the afternoon between 14:31-16:00 h. Given that their study also took place along the Lower Rio Negro, their findings reinforce the importance of further studying diurnal patterns of botos in this region, in order to better understand potential temporal overlap between humans and botos.…”

Over the past several decades, concern has grown over the rising mortality of the Amazon river dolphin (‘boto’) from increased human–dolphin interactions. Among these interactions are tourist attractions involving up-close feeding encounters with the botos, confrontations with fishers, and an illegal fishing practice that uses dolphin flesh as fish bait. Drawing on original data sourced from in-depth semi-structured interviews and household surveys, existing studies on boto habitat preferences and seasonal movement, and remotely-sensed data, this paper discusses the spatial and temporal overlap between humans and dolphins in a region outside of Manaus, Amazonas in the central Brazilian Amazon. Results suggest that there is considerable spatial overlap between boto habitat and spaces used for fishing and tourism activities; additionally, overall potential for conflict is greatest during the high-water season.

“…It is a forest type with one of the lowest indexes of species richness in the Amazon (Montero and Latrubesse 2013). The Negro River sustains a rich fish diversity of over 1,000 species (Chao 2001) and other aquatic vertebrates including aquatic mammals (Crema et al 2020, Vidal et al 2021). In the park there were no inhabitants, it is used for ecotourism activities, but hunting, fishing, and logging in the park occur illegally (Hallwass et al 2020).…”

“…In Brazil, a country with ample natural beauty and with much of it still in a good state of conservation, there is a demand for interaction tourism with fauna (Tischer et al 2013, Macdonald et al 2017, Tortato and Izzo 2017). Examples include sea turtle tourism on the coast (Pegas and Stronza 2010), Amazon river dolphin ( Inia geoffrensis ) tours (Vidal et al 2020, 2021), jaguar ( Panthera onca ) viewing in the Pantanal (Peralta 2012, Nassar et al 2013), and harpy eagle ( Harpia harpyja ) watching (Miranda et al 2021). In the Amazon, ecotourism with black caiman ( Melanosuchus niger ) and spectacled caiman ( Caiman crocodilus ), the most abundant and widely distributed of Amazonian crocodilian species in central Amazonia (Marioni et al 2021), has great potential to allow tourists to learn about, observe, and interact with caimans in Amazonian flooded forests (Rosenblatt et al 2021).…”

Ecotourism is a strategy for biodiversity conservation, but it involves possible negative effects on animal health and welfare. Large predators such as crocodilians are one of the great public attractions sought after for tourist interactions. Interactions with wild animals and humans can hyperstimulate the hypothalamic‐pituitary‐adrenal axis in the short term, in the case of crocodilians showing an increased corticosterone level, which is indicative of physiological stress. Between September and December 2019, we simulated interactions between tourists and Amazonian crocodilians at Anavilhanas National Park in Central Amazonia, Brazil to evaluate the effects of handling and use of photographic flashes on black caiman (Melanosuchus niger) and spectacled caiman (Caiman crocodilus) on circulating corticosterone and lactate. Corticosterone levels increased 1.7‐fold during handling and 2.7‐fold when exposed to photographic flashes in black caiman but not in spectacled caiman. Increased corticosterone concentrations in black caiman were characterized by an increase caused by handling and were more intense after flashes than in controls, but the combination of handling and flash had no effect. During handling in simulated tourist interactions, anaerobic respiration increased lactate in black caiman but not in spectacled caiman. The effect of simulated tourist interactions with Amazonian crocodilians was dependent on the handling and especially on flash use in black caiman. The results can assist management, conservation programs, and public policies, especially in programs based on tourism interaction with Amazonian crocodilians.
