RESUMO

La Reserva de la Biosfera Maya (RBM) es un área protegida de relevancia nacional, regional y mundial por la diversidad biológica asociada y los beneficios que se obtienen de esta. En su plan maestro se plantea el conjunto de elementos de conservación a partir de los cuales se orientan estrategias y se evalúa la efectividad de manejo de dicha reserva, entre los cuales se incluye a Tapirella bairdii (tapir), por lo que es importante contar con un monitoreo de esta especie como una herramienta para la administración de esta reserva. En el 2015 se inició el desarrollo de un protocolo de monitoreo basado en la estimación de la probabilidad de ocupación y el presente estudio constituye la continuación de esta iniciativa a través de la implementación de las temporadas de muestreo en 2017 y 2018. Se registró la presencia del tapir en cinco zonas núcleo de la RBM empleando trampas cámara y se estimó la probabilidad de ocupación. Los valores estimados sugieren una rela¬ción de la ocupación con la integridad ecológica, en la cual hay una mayor ocupación en áreas con menor perturbación. Se generaron modelos con cinco covariables relacionadas con amenazas potenciales, sin embargo fue el modelo nulo el que se seleccionó de acuerdo al criterio definido. Los resultados sugieren que la integridad ecológica en las áreas de estudio está siendo afectada como consecuencia de las presiones antrópicas por lo que es necesario el fortalecimiento de aquellas con menores valores de ocupación


The Maya Biosphere Reserve (MBR) is a protected area of national, regional and global relevance due to the associated bio¬logical diversity and the benefits obtained from it. In its master plan, a set of conservation elements are selected, on which strategies are oriented and the management effectiveness is evaluated, among which Tapirella bairdii (Baird's tapir) is included, so it is important to have a monitoring of this species as a tool for the management of this reserve. In 2015, the development of a monitoring protocol based on the estimation of the probability of occupancy started and the present study constitutes the continuation of this initiative through the implementation of the sampling seasons in 2017 and 2018. It was registered the presence of the tapir in five core areas of the MBR using camera traps and the probability of occupancy was estimated. The estimated values in the study areas suggest a relationship of occupancy with the ecological integrity, in which there is a greater occupancy in areas with less disturbance. Models with five covariates related to potential threats were generated, however it was the null model that was selected according to the defined criteria. The results indicate that ecological integrity in the study areas is being affected as a result of the anthropic pressures, so it is necessary to strengthen those with lower occupancy values

RESUMO

In this manuscript, as a starting point, the ancient and current distribution of the genus Tapirus are summarized, from its origins, apparently in Europe, to current ranges. Subsequently, original and current tapir habitats are described, as well as changes in ancient habitats. As the manuscript goes on, we examine the ways in which tapir species interact with their habitats and the main aspects of habitat use, spatial ecology and adaptability. Having reviewed the historic and current distribution of tapirs, as well as their use and selection of habitats, we introduce the concept of adaptability, considering that some of the tapir physiological characteristics and behavioral strategies can reduce the negative impact of habitat alteration and climate change. Finally, we provide recommendations for future research priorities. The conservation community is still missing important pieces of information for the effective conservation of tapirs and their remaining habitats in Central and South America and Southeast Asia. Reconstructing how tapir species reached their current distribution ranges, interpreting how they interact with their habitats and gathering information regarding the strategies they use to cope with habitat changes will increase our understanding about these animals and contribute to the development of conservation strategies.
