“…A higher edge density is coupled with less habitat area, limiting the capacity of the landscape to support medium and large-sized mammal species. Pozo-Montuy et al (2019) observed that medium- and large-sized mammals are significantly less abundant and diverse in the REBISO buffer zone (i.e., where the variegated windows are located). Such reduction in mammal density can cause a marked decrease in dung quantity and availability, thus limiting the growth of dung beetle populations ( Nichols et al, 2009 ).…”

Background Anthropized landscapes play a crucial role in biodiversity conservation, as they encompass about 90% of the remaining tropical forest. Effective conservation strategies require a deep understanding of how anthropic disturbances determine diversity patterns across these landscapes. Here, we evaluated how attributes and assembly mechanisms of dung beetle communities vary across the Selva El Ocote Biosphere Reserve (REBISO) landscape. Methods Community attributes (species diversity, abundance, and biomass) were assessed at the landscape scale, using spatial windows and vegetation classes. Windows were categorized as intact, variegated, or fragmented based on their percent cover of tropical forest. The vegetation classes analyzed were tropical forest, second-growth forest, and pastures. Results We collected 15,457 individuals and 55 species. Variegated windows, tropical forests, and second-growth forests showed the highest diversity values, while the lowest values were found in intact windows and pastures. Landscape fragmentation was positively and strongly related to dung beetle diversity and negatively related to their abundance; biomass was positively associated with forest cover. Beta diversity was the primary driver of the high dung beetle diversity in the landscape analyzed. Discussion The landscape heterogeneity and its biodiversity-friendly matrix facilitate the complementarity of dung beetle assemblages in the Selva El Ocote Biosphere Reserve. Random processes govern beta diversity patterns in intact and variegated windows. Therefore, vegetation cover in the region is sufficient to maintain a continuous flow of dung beetles between forested landscape segments. However, intense anthropic disturbances acted as deterministic environmental filters in fragmented windows and pastures sites, leading to biotic homogenization processes. Our results suggest that increasing habitat variegation in highly fragmented sites is an effective strategy to prevent or buffer homogenization processes in the REBISO landscape.

“…En toda el área de estudio, otro factor frecuente de la degradación de los recursos forestales es la tala ilegal para satisfacer la alta demanda doméstica y comercial de leña para cocinar (Escobar-Ocampo et al, 2009;Márquez-Reynoso et al, 2017). Estos ilícitos ocurren debido a la falta de recursos humanos y económicos para cumplir correctamente con las funciones de vigilancia, por la falta de coordinación con las autoridades locales y federales para frenar, y en la medida de lo posible, revertir los eventos de invasión por comunidades humanas a las zonas núcleo de la reserva, y por la falta de una visión y estrategia de manejo integral de los ecosistemas en las zonas núcleo y de amortiguamiento, en las que se consideren y concilien la compatibilidad de los medios de vida de los habitantes con los intereses de conservación del área protegida (Álvarez-Gordillo et al, 2017;Pozo-Montuy et al, 2019).…”

En este estudio analizamos los patrones espaciales y temporales de la cobertura y uso del suelo de la Reserva de la Biosfera Selva El Ocote (REBISO) y sus impactos en la conectividad funcional del paisaje de acuerdo con 2 especies indicadoras, la pava cojolita (Penelope purpurascens) y el pajuil (Penelopina nigra). Se emplearon mapas de cobertura del suelo de 2005 y 2019 elaborados con imágenes satelitales de alta resolución. La matriz predominante en ambos años fue la vegetación secundaria arbustiva (37.7%), en la que estuvieron inmersos bosques maduros (3.6%) y secundarios (35.8%), además de otras coberturas no forestales (22.9%). En este período se deforestaron 753 ha (0.7%) de bosques maduros y secundarios, y se regeneraron 226 ha (0.2%). Entre 2005 y 2019 se incrementó la fragmentación del área, pero el contagio (CONTAG) fue de 61.6%, lo que muestra una conectividad estructural intermedia de la vegetación forestal. La conectividad funcional para ambas especies se concentró en la zona núcleo I de la REBISO y para la pava cojolita, también hacia el sur de esta área. Se señalan las áreas críticas para mantener y mejorar la conectividad funcional de estas especies al interior de esta área protegida.

Knowledge about the biodiversity of Baja California has been obtained mainly from natural protected areas (NPAs), while some unprotected natural areas have been poorly studied. The Sierra Cucapá in the northeast of the peninsula is one example. The objectives of this study are 1) to integrate existing knowledge of bird, mammal, and reptile diversity in Cucapá from public databases, citizen science platforms, and information generated from fieldwork, 2) to identify the spatial distribution of records in the study area, 3) to compare the composition of vertebrate species of Cucapá with that of NPAs of northern part of the peninsula, and 4) to assess the biological conservation value of Cucapá. We obtained records of 150 species of native vertebrates (102 birds, 34 mammals, and 14 reptiles) of which 10 species of birds, four mammals, and seven reptiles are included in a risk extinction category. The different sources of information contributed in a complementary way to the species inventories. Large areas in western and northern Cucapá lack records. The total difference in species composition between Cucapá and nearby NPAs ranged between 58 and 69% for birds, 61 and 79% for mammals, and 69 and 87% for reptiles. The species richness of Cucapá, its particular species composition, the presence of species in risk extinction categories, and the number and size of unexplored areas indicate that this area represents an opportunity for biological conservation in the northern part of the Peninsula. This work provides compelling data for the protection of Cucapá.
