“…Altered habitats, for example for agriculture, palm oil plantations and pasture, are usually avoided by tapirs, and the expansion of these types of land-use are considered to be a major threat to wild tapir populations (Gemita et al 2007;Medici 2010). Trails for tourism and highly disturbed areas were found to be avoided by Baird's tapirs in the Sierra Madre of Chiapas and the Lacandon Forest, Mexico (Lira Torres et al 2004;Tejeda-Cruz et al 2009).…”

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.

“…In fact, Caro (2001) points out that differences in mammal richness and abundance between protected areas and human-influenced sites do exist, but he does not identify causes. Similarly, for Mexico, Urquiza-Hass et al (2009) and Tejeda et al (2009) found different responses from large vertebrates to varied expressions of human activities. Our results do not show a clear trend in the influence of the local-scale human activities we considered on the richness and abundance of medium and large-sized mammals.…”

We evaluated the influence of six human activities (related variables) on the richness and abundance of large and medium-sized mammals in the southern portion of the Lacandon Rainforest, including protected and non-protected areas. The human activities measured have different influences on mammal richness and abundance. Our results show that some human activities (human density and anthropogenic land cover, and agriculture/cattle ranching) had no effect on large and medium-sized mammal populations, but communitybased protection, such as medium levels of tourism and hunting, had a negative influence 2 on richness and abundance. Those variables negatively influencing the mammal community were reported in one of the study sites. Data indicate both an opportunity for applied integral conservation actions that involve people and their activities, as well as an opportunity to support biodiversity conservation in agricultural landscapes by integrating human activities with protected areas and conservation.

“…Asimismo, es importante resaltar que sólo se registraron en alrededor del 20 % de los transectos recorridos en estas áreas, lo que podría ser un indicador de que la abundancia es relativamente baja en comparación con otras áreas como Calakmul (Reyna-Hurtado y Tanner 2005) o la Lacandona (Tejeda-Cruz et al 2009). Los resultados en el ACP y la regresión logística indican que Miguel Colorado y Centenario-La Rigueña tienen gran importancia para las especies de Mazama en el oeste de Campeche, pues ambas áreas se caracterizan por tener una cubierta vegetal constituida en su mayor parte por selvas conservadas con baja densidad de ganado.…”

“…En el caso del M. temama, se ha considerado un especialista pues prefiere sitios conservados Bello-Gutiérrez et al 2010). No obstante, la especie comúnmente se ha registrado en acahuales, zonas fragmentadas y sitios de cultivo (Medellín y Equihua 1998;Tejeda-Cruz et al 2009;Bello-Gutiérrez et al 2010;Thornton et al 2011;Garmendia et al 2013;García-Marmolejo et al 2015). En el caso del microhábitat, se ha observado que la condición para la presencia de M. temama es que el sitio ofrezca una densa cobertura de protección vertical que le permita escapar de sus depredadores (Bello-Gutiérrez et al 2010) y especies vegetales importantes para su alimentación (García-Marmolejo et al 2015).…”

The brocket deer (Mazama temama and M. pandora) are two of the Mexican tropical deer with great importance for subsistence and sport hunters. Brocket deer are considered species with preference for pristine habitats conserved, however at the landscape level, factors such as hunting pressure could influence the presence and abundance of these species. Campeche, is the only Mexican state where it has been authorized the exploitation of the brocket deer for sport hunting. This hunting pressure along with the intense subsistence hunting that occurs in Campeche, could have important effects on the conservation of the species. Establishing what factors determine the presence of the species at the landscape level is essential to elaborate comprehensive management plans of these species to allow their long-term conservation. The aim of this study was to determine the habitat variables at the landscape level that influence the brocket deer presence in the central-western area of Campeche State in Mexico. The study area in the state of Campeche (19° 15' N, -91º 20´ W) was divided into six study regions (Chekubul-Cristalina; Chenkan; Chicbul-Km 74; Pixtún-Felipe Carrillo Puerto, Miguel Colorado; Centenario-La Rigueña) following the main paved road of the area and according to the conservation level of the natural ecosystems, presence of flooded areas, and intensity of the human activities where we determine the presence of brocket deer. We searched for brocket deer tracks along 263 transects of 500 m each. The tracks were identified to genus only. The presence/absence of brocket deer in the transects was combined with variables of human and natural origin of the study area in a geographical information system. We use principal component analysis and a logistic regression to determine the relationship between variables and the presence/absence of the brocket deer. We were not able to distinguish by their tracks the two potentially distributed species of brocket deer in the area. Due to this constraint, we did not perform a distinction between both species and all the observed tracks were classified as brocket deer. We found that brocket deer were present only in three of the six studied regions: Miguel Colorado (21.3 % transect had brocket deer presence), Centenario-La Rigueña (20.4 %) and Chenkan (1.7 %). The principal component analysis indicated that the variables determining the presence of brocket deer were, the percentage of preserved forest and distance to pastures, positively associated, while livestock density was negative. The best model obtained by the logistic regression showed that the presence of brocket deer increased when the percentage of preserved forests around transect is increased, while decreasing with increasing livestock density. The presence of conserved forests favors the presence of brocket deer in the study area, while a higher density of cattle decreases the probability of detection. The few records of brocket deer in flooded zones in this study and the lack of detection of the species in previo...
