“…The Mesoamerican cane toad, Rhinella horribilis, is a species with a worldwide distribution found from the west of the Andes and Mexico (distributed on the Pacific and Gulf coasts near the margins of water sources and human settlements). 1,2 Nine species of ticks are known to parasitise toads of the genus Rhinella, with Amblyomma dissimile and Amblyomma rotundatum being the most common. These generally use amphibians and reptiles as hosts; however, they can accidentally parasitise birds and mammals (including humans).…”

Background and Research Aims: Morphological and physiological effects of anthropogenic metals have been the focus of several studies in the Sierra de Huautla Biosphere Reserve (REBIOSH, Mexico) but little is known about how they affect anurans in the area. We evaluated metal bioaccumulation in anurans from streams in the REBIOSH and examined anuran communities in five sites at different positions relative to abandoned mine tailings. Methods: Three and two sites were located upstream and downstream from mine tailings, respectively. We collected anuran community information and obtained sediment, water and liver samples for metal quantification from each site. Results: Concentrations of Cu, Pb, Zn and Mn in water, and Zn, Mn, Fe and Cr in sediment, were significantly different among sites. We found bioaccumulation of Pb, Zn and Fe in livers of Smilisca baudinii, Lithobates spectabilis, L. zweifeli and Rhinella horribilis, species with different life traits. We found similar among-site species richness and diversity. Communities were dominated by L. zweifeli, R. horribilis and S. baudinii. Dominance was highest in sites distant from mine tailings. Agalychnis dacnicolor, Tlalocohyla smithii and Hypopachus variolosus were only present in sites located closest to mine tailings. Conclusion: We did not detect an effect of metal bioacummulation on anuran communities, but our findings suggest a potential effect on certain species in the protected area. Our results form a baseline for future explorations of the impacts of metals in the region. Implications for Conservation: Toxic metal bioaccumulation has potential for reducing anuran genetic variability and altering sexual proportions and fecundity, potentially leading to anuran extirpations. We provide first evidence for metal bioaccumulation in anurans in the protected area, and one of few studies on its anuran communities. Our evidence can serve as guidance to ameliorate effects of legacy metal mining in this biodiversity hotspot.

Human perceptions vary between rural and urban environments, determining the degree to which people are able to coexist with biodiversity. It is important to identify the sociodemographic factors that determine these local perceptions to adjust amphibian conservation strategies in recognition of the particular conditions of different human communities. In this research, the effect of the urban or rural location where people live and sociodemographic variables in the knowledge and perceptions about amphibians was determined. The data were collected through individual semi-structured surveys of 401 participants. We measured seven response variables through the Likert scale, which ranges from 1 (totally disagree) to 5 (totally agree). For each response variable, a multivariate analysis of variance was performed. Ninety-two percent of people correctly recognized frogs and toads as amphibians, but there was confusion in classifying caecilians and salamanders within this group or including reptiles within amphibians. This confusion was more evident for women from urban locality. Positive perceptions of amphibians varied between urban and rural locality for young adults, people with a high school education level, and people without formal education. Negative beliefs varied between urban and rural locations for women, adolescents, young adults, and professionals. Half of the people accepted information on the conservation of amphibians. Positive perceptions of people about amphibians should be used as a flag to strengthen environmental educational strategies, mainly in urban locations. The results suggest that amphibian conservation plans that aim to inform and educate the public should be focused differently for age groups, genders, and educational level for people in urban and rural locations.
