Invasive species are top threat to biodiversity because of their negative effects on floral and faunal species, food web, on ecosystems and their habitat. Their inherent capability to adjust in wide range of environmental conditions and spread at higher pace with economic activities like travel, trade and tourism have necessitated a concern for their prevention and protection. This has been recognized by Convention on Biodiversity that calls the contracting parties to prevent introduction and control or eradication of invasive species. Nepal as a signatory to this convention has to take essential legal and managerial actions to abide by the convention. This paper reviews some literatures and existing legal documents dealing with the invasive species management. The paper finds out that there is impact of Mikenia micrantha in Chitwan National Park and it may affect the productivity the area. There are legal provisions and institutional setup at National and local level under different acts, regulations and guidelines that influence the introduction, control and eradication of this species. This paper recommends that the full functioning of these provisions and institutional setup is required to manage the invasive species.

ABSTRACT All termites have established a wide range of associations with symbiotic microbes in their guts. Some termite species are also associated with microbes that grow in their nests, but the prevalence of these associations remains largely unknown. Here, we studied the bacterial communities associated with the termites and galleries of three wood-feeding termite species by using 16S rRNA gene amplicon sequencing. We found that the compositions of bacterial communities among termite bodies, termite galleries, and control wood fragments devoid of termite activities differ in a species-specific manner. Termite galleries were enriched in bacterial operational taxonomic units (OTUs) belonging to Rhizobiales and Actinobacteria, which were often shared by several termite species. The abundance of several bacterial OTUs, such as Bacillus, Clostridium, Corynebacterium, and Staphylococcus, was reduced in termite galleries. Our results demonstrate that both termite guts and termite galleries harbor unique bacterial communities. IMPORTANCE As is the case for all ecosystem engineers, termites impact their habitat by their activities, potentially affecting bacterial communities. Here, we studied three wood-feeding termite species and found that they influence the composition of the bacterial communities in their surrounding environment. Termite activities have positive effects on Rhizobiales and Actinobacteria abundance and negative effects on the abundance of several ubiquitous genera, such as Bacillus, Clostridium, Corynebacterium, and Staphylococcus. Our results demonstrate that termite galleries harbor unique bacterial communities.

Invasive species are major contributors to global biodiversity decline. Invasive mammalian species (IMS), in particular, have profound negative effects in island systems that contain disproportionally high levels of species richness and endemism. The eradication and control of IMS have become important conservation tools for managing species invasions on islands, yet these management operations are often subject to failure due to knowledge gaps surrounding species- and system-specific characteristics, including invasion pathways and contemporary migration patterns. Here, we synthesize the literature on ways in which genetic and genomic tools have effectively informed IMS management on islands, specifically associated with the development and modification of biosecurity protocols, and the design and implementation of eradication and control programs. In spite of their demonstrated utility, we then explore the challenges that are preventing genetics and genomics from being implemented more frequently in IMS management operations from both academic and non-academic perspectives, and suggest possible solutions for breaking down these barriers. Finally, we discuss the potential application of genome editing to the future management of invasive species on islands, including the current state of the field and why islands may be effective targets for this emerging technology.

Understanding the role of invasive species in ecosystem functioning represents one of the main challenges in ecology. Pteridium aquilinum is a successful cosmopolitan invasive species with negative effects on the ecological mechanisms that allow secondary succession. In this study we evaluated whether P. aquilinum favours the establishment of alternative states, as well as the effect of recovery strategies on the secondary succession. A random stratified sampling was established with three treatments, each one with at least 50 year of fern invasion and with variations on the periodicity of fires and cuttings (chapeos) vs one control without fern bracken We determined the species richness and composition, as well as the relative importance value (IVI) in each treatment. We found that P. aquilinum decreases the action of the mechanisms that allow secondary succession, particularly facilitation. The recovery strategies consist in monthly cuttings and control fires allow to recover the secondary succession and eventually, the regeneration of areas invaded by P. aquilinum. Our study has relevant implications on the ecology of alternative state, and in practical strategies to maintain tropical forests, as well as for the maintenance of environmental services and sustainability.

Preliminary Research

Previously, we were familiar with the subsidy mechanism in all socio-economic activities. Entering the period of renovation, we have realized that the subsidy mechanism has negative effects on the innovation of social activities by discouraging the creativity of individuals and organizations. And now, the "subsidy" still exists in the management culture in production, business or even in the field of training. The change of the market-oriented economy has required: the autonomy of organizations to be self-responsible is extremely necessary. Through a survey of Vietnam's legal documents, the research team identified two approaches to university autonomy: academic approach and financial approach. Preliminary research leads to the notion that university autonomy must be academic autonomy. In order to achieve academic autonomy, all policies must acknowledge the importance of the novelty of science.

Abstract: A series of imperial decrees of the 1820s ordering the establishment of a Greco-Uniate Theological Collegium and appropriate consistories contributed to the spread of the autocratic synodal system of government and the establishment of control over Greek Uniate church institutions in the annexed territories of Right-Bank Ukraine. As a result, the Greco-Uniate Church was put on hold in favor of the government's favorable grounds for the rapid localization of its activities. Basilian accusations of supporting the Polish November Uprising of 1830-1831 made it possible to liquidate the OSBM and most monasteries. The transfer of the Pochaiv Monastery to the ownership of the Orthodox clergy in 1831 was a milestone in the liquidation of the Greco-Uniate Church and the establishment of a Russian-style Orthodox mono-confessionalism. On the basis of archival documents, the political motivation of the emperor's decree to confiscate the Pochayiv Monastery from the Basilians with all its property and capital was confirmed. The transfer to the category of monasteries of the 1st class and the granting of the status of a lavra indicated its special role in strengthening the position of the autocracy in the western region of the Russian Empire. The orders of the Holy Synod outline the key tasks of ensuring the viability of the Lavra as an Orthodox religious center: the introduction of continuous worship, strengthening the personal composition of the population, delimitation of spiritual responsibilities, clarifying the affiliation of the printing house. However, maintaining the rhythm of worship and financial and economic activities established by the Basilians proved to be a difficult task, the solution of which required ten years of hard work. In order to make quick changes in the monastery, decisions were made by the emperor and senior government officials, and government agencies were involved at the local level, which required the coordination of actions of all parties to the process.

The ecological impacts of invasive species are highly variable and mediated by many factors, including both habitat and population abundance. Lionfish Pterois volitans are an invasive marine species which have high reported detrimental effects on prey populations, but whose effects relative to native predators are currently unknown for the recently colonized eastern Gulf of Mexico. We used functional response (FR) methodology to assess the ecological impact of lionfish relative to 2 functionally similar native species (red grouper Epinephelus morio and graysby grouper Cephalopholis cruentata) foraging in a heterogeneous environment. We then combined the per capita impact of each species with their field abundance to obtain a Relative Impact Potential (RIP). RIP assesses the broader ecological impact of invasive relative to native predators, the magnitude of which predicts community-level negative effects of invasive species. Lionfish FR and overall consumption rate was intermediate to that of red grouper (higher) and graysby grouper (lower). However, lionfish had the highest capture efficiency of all species, which was invariant of habitat. Much higher field abundance of lionfish resulted in high RIPs relative to both grouper species, demonstrating that the ecological impact of lionfish in this region will be driven mainly by high abundance and high predator efficiency rather than per capita effect. Our comparative study is the first empirical assessment of lionfish per capita impact and RIP in this region and is one of few such studies to quantify the FR of a marine predator.

Alumina refineries are among the leading sources of atmospheric air pollution with a wide range of pollutants hazardous to human respiratory organs. It is relevant to study and evaluate the occurrence of the risks for development of respiratory diseases in children living in the area affected by the emission components of an alumina refinery. We assessed air quality of the area under observation and comparison according to monitoring observations, risk of non-carcinogenic effects from the respiratory organs. The content of chemicals in the blood and urine adequate to risk factors was quantified. The structure of individual groups of respiratory diseases was analyzed. The causal relationships of violations of laboratory parameters with an increased content of chemicals in biological media were evaluated. It was found that an aerogenic exposure of chemical pollutants is formed on the territory with the production of metallurgical alumina. It determines the risk for development of respiratory diseases, exceeding an acceptable level up to 49.9 times. In the exposed children, the content of manganese, chromium, nickel, copper, xylenes, formaldehyde and aluminum, fluoride ion in the urine was increased to 4.2 times in relation to the indices in the comparison group. A high level of additional respiratory morbidity(1.8 times) was revealed. Chronic lymphoproliferative diseases of the nasopharynx and inflammatory diseases of the upper respiratory tract (up to 6.6 times more often), inflammatory diseases with a predominance of the mechanism of allergic inflammation ( up to 2.1 times more often)are more often detected in the framework of the respiratory diseases. Negative effects on the part of the respiratory system in the form of activation of antioxidant processes, the development of an inflammatory reaction, local, general and specific sensitization of the respiratory tract were established. It confirms the occurrence of the risks for the development of respiratory diseases in children in the exposure area of the chemical factors of alumina refinery-associated economic activity.
