ABSTRACTWe present distribution range extentions for five species of mammals from the Sierra Gorda de Guanajuato Biosphere Reserve in state of Guanajuato, Mexico. These are two felids: Lynx rufus and Puma concolor, as well as the western speckled skunk Spilogale gracilis, the peccari Dicotyles crassus, and the coati Nasua narica. The presence of these records reflects the importance of the Sierra Gorda de Guanajuato Biosphere Reserve as one of the main protected natural areas of Guanajuato, Mexico, since this area constitutes a natural bridge between species of neartic and neotropical affinity. This type of study reaffirms the need to continue conducting regional and local biological inventories in Mexico.Key words: Range extensión, camera-traps, Victoria, Guanajuato, biological corridor.Palabras clave: Distribución, cámaras trampa, Victoria, Guanajuato, corredores biológicos.

An important task of modern ecology is the modeling of the spatial distribution of organisms. Of particular relevance is the modeling of the distribution of rare species in protected natural areas. The paper discusses the main stages and presents the results of modeling the habitat suitability of the Central Forest State Nature Biosphere Reserve (Russia, Tver region) for the red vole. This species is a rare and relict for the center of the Caspian-Baltic watershed. In the modelling the maximum entropy method (MaxEnt) was used. The basis for building the model was the field sampling of the authors, performed in July-August 2010-2014. Each year, trapping were carried out at 745 sampling points each of which has geographical referencing in the WGS 84. A total of 12238 trap-days were worked out and 141 red vole individuals were caught. In the process of modeling, the contribution to the species distribution of certain integral characteristics of habitats (relief, vegetation type and three vegetation spectral indices) was determined. A map model of habitat suitability for the red vole on the territory of the Reserve was built, which allowed to describe the spatial structure of the population groups of the species. The total areas of the most favorable sites for the habitat of the red vole on the reserve's territory were calculated.

The conservation status of an ecosystem is checked by studying the composition and diversity of the organisms that interact in trophic chains. The aim of this study was to evaluate the biodiversity of mites associated to Capsicum annuum L. var glabriusculum (Solanaceae) at three sampling sites corresponding to two Protected Natural Areas (PNA) in Tamaulipas state, Mexico. Samplings were carried out in “Cañón de la Peregrina” and “Altas Cumbres” situated in the PNA "Altas Cumbres" and “Ojo de Agua”, located in the "El Cielo" Biosphere Reserve. Mite diversity was H = 1.09 ± 0.14 in Ojo de Agua, and it was H = 1.08 ± 0.08 and H = 1.11 ± 0.06 in Altas Cumbres and Cañón de la Peregrina, respectively. A total of 47 species were identified belonging to 35 genera of 18 families associated to C. annuum L. var glabriusculum in Mexico. Predatory mite richness was higher than that of generalist and phytophagous mites (31, 11 and 5 species, respectively) for the two ANP. The similarity index of Jaccard between OA–AC (IJ = 0.257; P < 0.05), CP–AC (IJ = 0.293; P < 0.05) and AC–CP (IJ = 0.324; P < 0.05) was low. Pseudopronematalus sp. 4 (Iolinidae) was predatory mite most abundant in both ANP (Pi = 9.311); followed by Metaseiulus (Metaseiulus) negundinis (Denmark) (Phytoseiidae) only for ANP “Altas Cumbres” (Pi = 1.004). While for phytophagus mite, Aculops lycopersici (Tryon) (Eriophyidae) and Tetranychus merganser Boudreaux (Tetranychidae) presented the highest abundances in all sites (Pi = 79.919 and 5.142, respectively). The high number of mites species associated to chile piquín suggests stability in the PNA despite anthropogenic activities, and that the PNA works as a mite reservoir.

The common frog (Rana temporaria) and the moor frog (R. arvalis) lived in all green areas of Moscow until the end of the 20th century. The reduction in the area of woody vegetation, the destruction of breeding sites and introduction of the invasive fish Perccottus glenii contributed to the extinction of these amphibians in most of the city. The paper provides information on the distribution of brown frogs in Moscow based on the results of monitoring in 2020. R. temporaria was found in 37 localities in the Northwestern (6 points), Northern (3 points), Northeastern (1 point), Eastern (9 points), Southeastern (1 point), Southern (5 points), Southwestern (5 points) and Western (7 points) administrative districts. Eleven finds (29.7%) are located outside of specially protected natural areas. Most of the species’ habitats (30 points, or 81.1%) are isolated from other populations. R. arvalis was found in 14 localities in the Northwestern (3 points), Northern (3 points), Eastern (4 points), Southwestern (1 point) and Western (3 points) administrative districts of Moscow. Of all the finds noted, three ones (21.4%) are located outside of specially protected natural areas. The vast majority of the habitats of the species (10 points, or 71.4%) are isolated.

Las políticas sobre el combate de incendios dentro de áreas naturales protegidas han transitado de un enfoque de supresión a uno de manejo del fuego, lo que ha tenido consecuencias para las prácticas y las perspectivas de las poblaciones campesinas. En el estudio la pregunta es cómo la regulación, la restricción y la prohibición del uso y el manejo del fuego, cuyo objetivo es la conservación, confronta, trasforma o criminaliza dichas prácticas en las parcelas. Desde la ecología política se analiza la institucionalización del discurso del fuego en la Reserva de la Biosfera La Sepultura, en Chiapas. Por medio de entrevistas, encuestas y observación participante se reconstruye la modificación de las prácticas y de las perspectivas campesinas en la zona. Los resultados muestran que existe un cambio diferencial en el uso y la percepción del fuego, lo cual refiere a una capacidad adaptativa, junto a una especie de “clientelismo ambiental”, como respuesta a las políticas ambientales del gobierno. Las conclusiones apuntan a conocer la forma en que los habitantes de las áreas naturales protegidas están respondiendo al modelo de conservación neoliberal implementado en el país. From fire suppression to fire management in La Sepultura Biosphere Reserve in Chiapas: peasant perspectivesPolicies on firefighting within protected natural areas have shifted from a suppression approach to one of fire management, which has had consequences for the practices and perspectives of peasant populations. The study poses the question of how regulation, restriction and prohibition on the use and management of fire, whose objective is conservation, confront, transform or criminalize these practices in the parcels. From a political ecology perspective, the institutionalization of the discourse of fire in the La Sepultura Biosphere Reserve in Chiapas is analyzed. Through interviews, surveys and participant observation, modification of practices and peasant perspectives in the area is reconstructed. The results show that there is a differential change in the use and perception of fire, which refers to an adaptive capacity along with a sort of “environmental clientelism,” as a response to governmental environmental policies. The conclusions allow to know the way in which the inhabitants of the protected natural areas are responding to the neoliberal conservation model implemented in the country.

Special Nature Reserve (SNR) Gornje Podunavlje is located in the northwestern part of Serbia, on the left bank of the Danube, along the border of Croatia and Serbia. This area is a significant spatial unit for the development of nature-based tourism and ecotourism. It is part of Backo Podunavlje Biosphere Reserve, protected by UNESCO, and a wider area of Transboundary Biosphere Reserve Mura-Drava- Danube, which includes 10 protected natural areas in five countries. The research aims to examine the attitudes of the local population about the state of sustainable tourism development in the SNR Gornje Podunavlje using a questionnaire. A total of 205 respondents expressed their satisfaction with the environmental, economic, and socio-cultural aspects of sustainability. After quantitative analysis, the results of the research can provide nature conservation guidelines and specify the role of protected natural areas in sustainable tourism development. As the most important dimensions of sustainability, the residents highlighted the Socio-cultural and Institutional dimensions of sustainable tourism development. Slightly lower values, according to the attitudes of residents, were given to Environmental and Economic sustainability. The results of the research indicate that this destination can be important for the development of sustainable tourism. By adopting the planned management measures, this protected natural area can be a significant destination for ecotourism and other forms of nature-based tourism.

Diversity and activity patterns of medium and large mammals in La Encrucijada Biosphere Reserve, Chiapas, Mexico. In Mexico, wetlands occupy an important portion of the country, among them, mangroves are particularly diverse. La Encrucijada Biosphere Reserve (ENBIRE) is a coastal ecosystem of mangrove located along the Pacific Coastal Plain in the Southwestern portion of Chiapas state. The ENBIRE mangroves are among the most important of the American Pacific Coast, highlighting the role they play in the maintenance of the community of mammals on the coast of the state. There are few studies in Mexico related to the mammals associated with these ecosystems, our aim was to estimate the diversity and activity patterns of medium and large mammals in the ENBIRE. Sampling was conducted from August 2015 to August 2016 using camera traps. We obteined 1 851 independent photographs records, with a total sampling effort of 5 400 trap-days. Nineteen species of mammals were registered belonging to 15 families and seven orders, and five species were new records to the area. Six species present are listed, two as endangered and four as threatened. Interpolation and extrapolation analyzes showed an asymptotic trend in the curves for the rainy and dry seasons. The coverage of the sample for both seasons was 99.9 % and 99.8 %, respectively, indicating that both cases were a representative sample. According to the relative abundance index obtained, the most abundant species were Procyon lotor (IAR = 4.35), Nasua narica (IAR = 3.91), Philander opossum (IAR = 2.04), Cuniculus paca (IAR = 1.89), Didelphis marsupialis (IAR = 1.67) and Dasypus novemcinctus (IAR = 1.02). In terms of patterns of activity C. paca, P. opossum, D. marsupialis and D. novemcinctus were primarily nocturnal; P. lotor showed a tendency towards nocturnal habits but was also recorded during the day; N. narica was mainly diurnal. This information can be useful to the creation of management programs and the conservation of medium and large mammals in the ENBIRE, especially for species at risk. Rev. Biol. Trop. 66(2): 634-646.
