“…Another threat is the exploitation of eggs and hatchlings for food and aphrodisiac purposes, which has prevented them from maintaining a regular reproductive rate [60]. It has been observed that in some communities a large number of hatchlings are captured and used as pets for children in the communities [46,54], or are sold to settlers for the same purpose [24].…”

“…In Latin America and the Caribbean, a significant number of rural communities have integrated tourism activities into their social, productive and economic dynamics as an alternative to fight poverty, incorporating the inhabitants, who are sometimes indigenous and mestizo groups, generating a new form of tourism that has been called Rural Community Tourism [19][20][21][22]. This type of tourism has been implemented in rural areas where the local inhabitants, organized collectively, play a participatory role in its progress, management and monitoring, ensuring respect for the natural environment, socio-cultural [23] and ancestral values of their community [24], allowing a pleasant, favorable and reciprocal enjoyment of experiences between local people and tourists (visitors). This interrelation tourist-rural community should be characterized by justice in the equitable distribution of the benefits generated by the execution [22,25,26].…”

Biodiversity at the species and ecosystem level is an important basis for tourism, especially for tourism economies in landscapes optimal for the conservation and sustainable use of biodiversity, which are addressed under the Convention on Biological Diversity. In the last two decades, the Podocnemis Unifilis turtle has presented problems represented in a decrease of individuals in their populations in the Ecuadorian Amazon. The objective of the study was to describe the characteristics and current situation of the charapa turtle (Podocnemis Unifilis), to analyze the perception of the community of the Indillama River towards this species and finally to establish a proposal for its conservation with a socio-economic contribution from the community tourism segment. The methodology used consisted of a bibliographic review, semi-structured interviews and expert judgment. The main results indicate that the charapa turtle has had population problems in the last 30 years due to various anthropogenic pressures. The inhabitants of the Río Indillama community perceive this species mainly as a source of economic income (sale of individuals and their eggs) and food by consuming their eggs and adult individuals. Finally, we present a proposal for conservation through tourism that provides experiential activities for the collection of P. unifilis eggs, nesting and release (sponsorship) of individuals, providing economic benefits to local communities. This will contribute to its conservation and local socioeconomic development.

Impacts of dams on freshwater turtles: a global review to identify conservation solutions

Dams create many impacts on freshwater ecosystems and biodiversity. Freshwater turtles are at direct and indirect risk due to changes caused by damming including the loss of terrestrial and aquatic nesting and feeding habitats, changes to resource availability and reduced dispersal. We reviewed the global scientific literature that evaluated the impact of dams on freshwater turtles, and carried out additional searches of literature published in seventeen languages for studies evaluating actions to mitigate the impact of dams. The search produced 43 published articles documenting dam impacts on 29 freshwater turtle species from seven families (Chelidae, Chelydridae, Emydidae, Geoemydidae, Kinosternidae, Podocnemididae and Trionychidae) in 13 countries. More than a third of studies (41.9%, n = 18) focused on nine North American species of the Emydidae. Few studies were found from Europe and Asia and none from Africa. The number of studies, life-history stage studied and threat status differed significantly between temperate and tropical latitudes. Most studies were from temperate latitudes, where studies focused more on adults and less threatened species compared with tropical latitudes. Studies evaluated dam impacts as barriers and changes to water flow and quality, but no studies were found that assessed turtles and changes to land cover or mercury caused by dams. More than half of the studies (59%, n = 24) suggested actions to help mitigate dam impacts. Yet, only four studies on three temperate and one tropical species documented the effect of interventions (dam removal, flow management, artificial pond maintenance and community-based action). These findings demonstrate a lack of documented evidence evaluating dam impacts on freshwater turtles particularly in tropical regions. This lack of evidence reinforces the importance of strengthening and maintaining robust long-term studies of freshwater turtles needed to develop effective conservation actions for this group of vertebrates.

Conservation units alone are insufficient to protect Brazilian Amazonian chelonians

The creation of protected areas (PAs) is not always based on science; consequently, some aquatic species may not receive the same level of protection as terrestrial ones. The objective of this study was to identify priority areas for the conservation of chelonians in the Brazilian Amazon basin and assess the contribution of PAs, distinguishing between Full Protection Areas, Sustainable Use Areas, and Indigenous Lands for group protection. The entire species modeling procedure was carried out using Species Distribution Models. Location records were obtained from platforms such as SpeciesLink, GBIF, the Hydroatlas database, and WorldClim for bioclimatic variables adjusted with algorithms like Maximum Entropy, Random Forest, Support Vector Machine, and Gaussian-Bayesian. Indigenous lands cover more than 50% of the distribution areas of chelonian species in the Brazilian Amazon. Protected areas with higher conservation importance (Full Protection Areas and Sustainable Use Areas) hold less than 15% of the combined species distribution. Researchers face significant challenges when making decisions with models, especially in conservation efforts involving diverse taxa that differ significantly from one another within a group of individuals.
