“…In the Brazilian semi-arid region, where water is unpredictable, snakes may have morphological, physiological, behavioral and ecological adaptations to survive in this scenario (Da Costa et al, 2019). A recent study revealed that the diet is more important than the habitat to explain the partitioning of ecological niches by snakes, and thus, the coexistence of different species would be possible due to a high overlap in a specific niche dimension (microhabitat) would necessarily be possible due to a high overlap in a specific niche dimension (diet), which would avoid exclusion by competition (Di Pietro et al, 2020).…”

Snakebites represent an important, though neglected, public health problem especially in the Northeast of Brazil. There is still a large number of underreported cases, the collection of epidemiological data is deficient, and the ecological and epidemiological knowledge of this envenomation remains limited due to the lack of updated regional and local information. This study describes the epidemiological profile of snakebites recorded by the Notifiable Diseases Information System from 2008 to 2018 in the state of Ceará. The data were organized according to the municipalities of the health macro-regions, considering the variables: sex, snake, gravity and deaths. A total of 8,233 cases was found, with an annual incidence of 8.6/100,000 inhabitants, and a higher prevalence of accidents caused by Bothrops snakes (64%), in men (87.4%) in the Sobral region (25.5%). However, the highest incidence rate was found in the Sertão Central (299.7/100,000). Most cases were considered mild (62%), but the mortality rate was 0.07/100,000 and the case-fatality rate was 0.8%. Among the most affected municipalities, cities like Tauá (1.3%), Sobral (8.1%) and Fortaleza (8.5%) are concerning, considering that the case-fatality rates were above the national average (1%). Snakebites in Ceará follow a pattern similar to that of other states in the Northeast, with a high frequency of incidents where the causative snake is not identified (16%). Considering the gravity of snakebites, studies that evaluate the anthropic and environmental influence in the distribution of cases may help to define priority risk areas, to improve health surveillance and patient care.

“…tandiliensis Vega et al, 2008, Lygophis elegantissimus (Koslowsky, 1896), and Pristidactylus casuhatiensis (Gallardo, 1968). In our study, we employed these narrow-range reptiles as biodiversity surrogate species of the Pampas grassland because (1) they are representative and charismatic species that inhabit each of their main environments, (2) they are categorized as threatened by the IUCN (one Critically Endangered, one Endangered, two Vulnerable, one Least Concern, and two not categorized; IUCN, 2021), and (3) they have an essential ecological role in the ecosystem as they are part of the intermediate food chain levels, some preying on most of the insects and anurans present in the study area (Vega, 1999; Di Pietro et al, 2020b; respectively).…”

“…Since the habitats of Tandilia and Ventania highland grasslands are similar, we followed the categories proposed by Di Pietro et al (2020b) for habitat description and classification. We used only the data from the fieldwork since almost all the other sources of records do not have habitat description.…”

The study of biodiversity is a fundamental step to develop conservation strategies. Reptile populations are immersed in a global crisis, due to anthropic disturbances. Almost the entire Pampa ecoregion in Argentina was modified for agricultural and livestock activities, the only remnants of mountain native grasslands in Buenos Aires province being the Tandilia and Ventania mountain systems. Ventania reptiles have been exhaustively researched in last years, while Tandilia counts with fewer studies. We presented an actualized reptiles list of the Tandilia Mountain System. We used five data sources to collect presence records: literature, fieldwork, museum collection, citizen science, and a online database. The composition of reptiles from the Tandilia Mountain range includes 26 species in 12 families. Due to the presence of several endemic reptiles, and the representativeness of more than half of the reptiles of Pampa Ecoregion, Tandilia would be useful to determine conservation priority areas to conserve the native grassland and their reptile fauna.
