    New records of Cracids along a fragmented landscape in Central Mexico (Aves Cracidae)
    https://doi.org/10.31396/Biodiv.Jour.2018.9.4.339.344

    ABSTRACT
    The pava cojolita or crested guan (Penelope purpurascens Wagler, 1830) and the great curassow (Crax rubra Linnaeus, 1758) (Aves Cracidae) inhabit mature rainforests with low or null perturbation, making them potential indicator species. We report actual records of both species obtained through biodiversity monitoring undertaken in the Experimental Site “Las Margaritas” in the municipality of Hueytamalco at the Sierra Nororiental in the State of Puebla. The presence of both species indicates the importance of the Experimental Site “Las Margaritas” for their distribution within a highly fragmented area.

    Does local knowledge change after a species long term absence? The case of giant river otters Pteronura brasiliensis Gmelin, 1788 (Carnivora Mustelidae)

    ABSTRACT
    Public participation could be useful to determine species presence and ecological aspects, however it is possible that local knowledge of species whose populations had suffered a decrease could have changed. To determine current knowledge of giant river otter, Pteronura brasiliensis Gmelin, 1788 (Carnivora Mustelidae), we undertook a preliminary assessment based on 35 interviews preformed between June and August 2014 with natural resources users in the Pacaya-Samiria Reserve (Peru) aimed to determine the presence, feeding habits, reproduction periods, and threats. It was possible to determine that current knowledge cor- respond with available information in literature thus, I consider that it is possible to use public participation in cases of little known species that are recovering.

    Community monitors as researchers: determining vulnerable species distribution in a protected area of central Mexico
    https://doi.org/10.31396/Biodiv.Jour.2020.11.1.21.24

    ABSTRACT
    We designed a training workshop in biodiversity monitoring and natural resources management and conservation for rural communities of the Hydrographic Basin of the Necaxa River Protected Area, aiming to increase active participation. We presented 2 cases in which participants documented 2 vulnerable species, increasing the distribution of margay, Leopardus wiedii Schinz, 1821 (Mammalia Felidae) and recording the persistence of neotropical otter, Lontra longicaudis Olfers, 1818 (Mammalia Mustelidae). These records proved that with proper training, community monitors could generate new information on biodiversity distribution, provide evidence to traditional knowledge, and produce data to improve protected area management.
