The Power Elite

The hegemonic development discourse continues to promote mining as an activity that generates progress despite the considerable evidence to the contrary. The article analyzes Grupo Mexico’s history, the largest mining consortium in the country, as part of the power elite. It shows how it achieved a monopoly of the leading copper deposits in the north of the country thanks to its alliances with the Mexican State. Later on, we present the cartography of the expansion of its operations in the north of the country, including the opening of controversial mining projects in strategic areas for biodiversity conservation such as the Sea of Cortés, the Baja California peninsula and, the Monarch Butterfly Biosphere Reserve in Michoacán. Therefore, it is argued that it is important to consider companies’ environmental and social records when evaluating mining concessions’ renewal or revocation.

Landscape Ecological

Landscape Ecological Structure in the Eastern Part of the North Vidzeme Biosphere Reserve, Latvia Latvia is a country where the forest area has increased and habitat fragmentation has reversed compared with many other European countries. In order to examine the effect of this expansion on biodiversity, vegetation maps dating from 2002 and the years 1930-1936 were used for comparative landscape structure analyses while archive materials from forest plans, and data from the national forest management database were used for land use analysis. Four landscape ecoregions in the eastern side of the North Vidzeme Biosphere Reserve were selected for analysis. Landscape structure indicators derived from landscape ecology were used for the ecological assessment of land use changes. The total number of forest patches had decreased over the study period, but mean patch size had increased for all types of landscape element. This general change was found to vary between different landscape units in the study area. The biggest change in the area of forest patches occurred in the Rūjiena drumlin field, where the amount of forest patches decreased least and forest area increased the most. This study showed that the internal structure of the forest matrix changed substantially. This finding has implications for biodiversity protection if this trend of land use change continues.

Birch Forests

Birch forests from Betula litwinowii and Betula raddeana of the Northern macroslope of the Greater Caucasus with participation of Rhododendron caucasicum in the undergrowth are discussed in the article. The studies were carried out in 2017–2020 at the territory of Karachay-Cherkessia (Teberda State Natural Biosphere Reserve), Kabardino-Balkaria (Kabardino-Balkarian State High Mountain Reserve) and the Republic of Dagestan (Lak and Gunib districts, near the villages Burshi and Batsada). The characteristics of the growing conditions, analysis of the species and coenotic composition of communities are given. Birch forests with Rh. caucasicum are usually confined to the steep slopes of the northern exposure at the upper border of the forest belt, at an altitude of 1500–2800 m above sea level. The described communities can be divided into two groups depending on abundance and, consequently, influence Rh. caucasicum as an edificator. In the described communities there is a clear inverse correlation between the abundance of Rh. caucasicum with the projective cover of the grass-dwarf shrub layer. At the same time, the number of species in the grass-dwarf shrub layer doesn’t change significantly. The species composition of birch forests with the participation of Rh. caucasicum identified by us comprises 246 species of vascular plants. The herb-dwarf shrub layer is characterized by a relatively low species richness (on average, 26 species per sample plot). In these communities there are both characteristic forest species and representatives of subal-pine and, less often, alpine coenoses. Further study of communities of birch forests, which play sig-nificant water protection role, slope-holding and avalanche-barrier functions, is important for determining their current state, possible directions of changes, and assessing the need for protective measures in different regions.

AbstractFollowing severe population decline and local extinction due to massive habitat destruction and persecution, wildcats have recently reappeared in several parts of Germany’s low mountain region. It remains unknown how this reemergence occurred, specifically if local populations have been overlooked at low densities or if the species has successfully spread across the highly fragmented anthropogenic landscape. In the central German Rhön Mountains, for instance, wildcats were believed to be extinct during most of the twentieth century, however, the species was recently detected and subsequent genetic monitoring found the presence of a sizeable population. In this study, we used microsatellite and SNP genotypes from 146 wildcat individuals from 2008 to 2017 across a ~ 15,000 km2 area in the central German low mountain region to understand the population re-establishment of wildcats in the region. Bayesian clustering and subsequent analyses revealed that animals in the Rhön Mountains appear to be a mix from the two adjacent populations in the North and South of the area, suggesting a recent range expansion from two different directions. Both populations meet in the Rhön Biosphere Reserve, leading to an admixture of the northern, autochthonous, and the southern reintroduced wildcat population. While we cannot completely exclude the possibility of undetected population persistence, the high genetic homogeneity in the central German wildcat population and the lack of any signatures of past population decline in the Rhön favor a scenario of natural expansion. Our findings thus suggest that wildcats are well capable of rapid range expansion across richly structured landscape mosaics consisting of open land, settlements, and forest patches and document the potential of massive non-invasive genetic sampling when aiming to reconstruct the complex population and range dynamics of wildlife.

Introduction: In Niger, the degradation of ecosystems leads to a loss of biodiversity and an increase in the adverse effects of climate change, especially in the ecosystems contracted from the plateaux of the Niger W biosphere reserve. Objective: The objective of this study is to characterize the spatial variability of the flora according to the north-south rainfall gradient of the reserve. Methodology: Phytosociological surveys, an ascending hierarchical classification and a canonical analysis of correspondences between plant groups and environmental factors. Results-Discussion: The 126 inventoried species have 88 dicotyledons, 28 woody species, and 98 herbaceous species. The most common families are: Poaceae (21.42%), Fabaceae (12.69%), Rubiaceae (7.14%) and Convolvulaceae (6.34%). The biological spectrum is dominated by therophytes then microphanerophytes. The world chorology is marked by African species followed by palaeotropics or pantropicales, and at the African level, Sudano-Zambezian species are the most frequent. The presence of intermediate species (GC-SZ and GC-SZ-SahS) is noted. From north to south, 3 groups of plants were highlighted: the group with Sida cordifolia and Guiera senegalensis whose phytodiversity is reduced; Group II consisting of the subgrouping with Combretum nigricans and Microchloa indica and the subgrouping with Combretum micranthum and Gardenia sokotensis floristically rich, with however a regeneration dominated by Guiera senegalensis; grouping with Loudetia togoensis and Acacia macrostachya, in good state of conservation. Conclusion: The study made it possible to characterize floristically the various landscapes along the rainfall and anthropic gradient. Thus, in view of the structures of the stands observed, the distribution of floristic diversity increases according to a gradient of decreasing aridity from the periphery to the internal part of the reserve. From the north to the south there is a degraded part, a part gradually invaded by Guiera senegalensis and another well preserved. This work, which provides an overview of the state of conservation of the floristic diversity of the Niger W Biosphere Reserve, allows taking appropriate measures to safeguard our plant resources.

The purpose of this study is to explore the role of the North Vidzeme Biosphere Reserve’s image (functional, symbolic and experiential) in building young visitors’ intentions to visit biosphere reserves. Integrated research methods were used. An online survey was conducted for data collection (n=295), and focus group discussions and observations (three groups - two from Latvia and one from Estonia) were conducted about youth traveling behavior in the North Vidzeme Biosphere Reserve. Descriptive statistics and structural equation modeling were used to analyze data. Findings showed that the North Vidzeme Biosphere Reserve has a weak image in the perception of young people. Most respondents agreed that visiting biosphere reserves relieves stress, helps them to socialize, and allows them to escape from daily routine; additionally, they noted that they would visit protected areas more often if they would see their friends visiting them. Youth 15–19 was more excited, pleasureful, and excited about visiting biosphere reserves, but youth 20–25 was more neutral about it. Both groups agreed that there was a lack of advertisements and visibility of these areas on social media platforms. Research results showed that improving functional, symbolic, and emotional images of the North Vidzeme Biosphere Reserve will have a positive effect on youth visiting and revisiting intentions.
