“…In the case of reserves or natural protected areas, for example, the area of conservation is directly related to the viability of the wild populations, species richness and rates of immigration, among other factors [83]. In the case of the free-living UMAs, the reason lies more in the form in which they contribute to increasing the area dedicated to conservation, improving the connectivity among conserved areas and thus favoring the metapopulation dynamics of many wild species [84].…”

“…The same case could be replicated with other priority species managed in UMAs, for example, vascular plants such as Beaucarnea gracilis, Zamia furfuracea and Chamaedora metalica; birds such as Colinus virginianus, Ara macao and Ara militaris; mammals such as Alouatta palliata, Ateles geoffroyi and Tayassus pecari; amphibians such as axolotl (Ambystoma mexicanum) and insects such as the monarch butterfly (Danaus plexippus). Many of these are native to the tropical humid forest and tropical montane cloud forest at a regional scale [84]. Likewise, other species (priority or otherwise) could be included in the management; conservation of these species may favor or contribute directly or indirectly to the conservation of ecosystems and secondary species, as is the case with the free-living UMAs of white-tailed deer (Odocoileus virginianus) [24,[60][61][62]68,87].…”

Impact of the Wildlife Management Units Policy on the Conservation of Species and Ecosystems of Southeastern Mexico

Wildlife in Latin America is subject to enormous pressures and, as in most countries, has been negatively impacted in Mexico. In 1997, the Mexican government implemented a policy of conservation and sustainable use of wildlife units (called UMAs, by their Spanish acronym) that comprises intensive and free-living management. Since then, no national or regional assessments have been conducted to estimate impacts and benefits even with 5529 registered UMAs now covering almost 20% of the national territory. The objective of this study was to characterize the SUMA (UMAs System) in a regional context in three states of southeastern Mexico. The impact of UMAs was studied in depth through a selection of representative case studies: three species of mangrove (Avicennia germinans, Laguncularia racemosa and Rhizophora mangle), ponytail palm (Beaucarnea recurvata), red cedar (Cedrela odorata) and white-tailed deer (Odocoileus virginianus), and a connectivity analysis, in order to evaluate the contribution of the UMAs to the conservation of species and ecosystems. The number of active UMAs at regional scale was 834, managing 273 species; 7.1% of the UMAs manage nationally-prioritized species, while 8.3% and 94.3% manage endemic and native species, respectively. Conservation of ecosystems has been successfully achieved through the UMAs that manage mangrove and white-tailed deer. We propose to promote the establishment of free-living UMAs that would contribute to increase the conservation areas. Finally, we highlight the relevance of regional-scale spatial analysis as an important tool for improving environmental policy and conservation strategies.

“…Lo anterior, motivó el estudio del venado bura en la Reserva de la Biósfera Mapimí, con el objetivo de determinar si se estaba en presencia de una metapoblación. Finalmente se pudo establecer que las poblaciones de venado bura en estudio si constituía una metapoblación (Sánchez & Gallina 2000), lo cual resultó fundamental para generar un plan de conservación de esta especie.…”

Dada una metapoblación, que como tal, se encuentra distribuida en fragmentos o parches, podemos pensar que esta está en riesgo de extinción si la cantidad de parches ocupados está disminuyendo. En este sentido, una medida de conservación a considerar podría ser la incorporación de individuos a parches desocupados. Este proceso es conocido como conservación ex situ. En el presente trabajo supondremos una metapoblación extinguiéndose, cuya dinámica será modelada matemáticamente a través del modelo planteado por Richard Levins en su trabajo "Some demographic and genetic consequences of environmental heterogeneity for biological control". Se incorporará al modelo el efecto de una medida de conservación ex situ, consistente en la colonización artifi cial de parches desocupados, con el propósito de evitar que la población total se extinga. La incorporación de esta medida de conservación será expresada a través de un sistema de ecuaciones diferenciales impulsivo, a partir del cual se generarán una serie de simulaciones, en orden a entender la dinámica a largo plazo y determinar qué factores infl uyen en el éxito de la medida de conservación.
