AbstractBiodiversity not only responds to environmental change, but has been shown to be one of the key drivers of ecosystem function and service delivery. Forest soil biodiversity is also governed by these principles, the structure of soil biological communities is clearly determined by spatial, temporal and hierarchical factors. Global environmental change, together with land-use change and forest ecosystem management, impacts the aboveground structure and composition of European forests. Due to the close link between the above- and belowground parts of forest ecosystems, we know that soil biodiversity is also impacted. However, very little is known about the nature of these impacts; effects they have on the overall level of biodiversity, the functions it fulfills, and on the future stability of forests and forest soils. Even though much remains to be learned about the relationships between soil biodiversity and forest ecosystem functionality, it is clear that better effort needs to be made to preserve existing soil biodiversity and forest conservation strategies taking soils into account must be considered.

Mangrove ecosystem is a complex tropical forest ecosystem that is able to live and to adapt in coastal environments.Unfortunatelly, its existence is vulnerable to the environmental change. Unless utilization of mangrove forest is notfollowed by enrichment and rehabilitation, it will lead to degradation of logged-over land such as pest and diseaseinfestation. The pest study was conducted in mangrove stands in PT. Bina Ovivipari Semesta (BIOS), Kubu Raya, WestKalimantan. The result of study consisted of three sample plots obtained from the average of mangrove pest on thecutting area of 2017 (93.33%), attack intensity (28%). Additionally, the average of cutting area of 2012 were at 91.95%and attack intensity (29%) while the protection forest obtained the average of attack at 79.23% and attack intensity(21.87%). The results of pest identification of mangrove arboretum were 9 pests, including pagoda bagworm (Pagodiellaspp.), bagworm (Acanthopsyche sp.), krama / tree climbing crab (Episesarma spp.), nacerdes beetle (Xanthochroa sp.),aphid (Prociphilus tessellatus), barnacles (Balanus amphitrite), snails (Gastropoda Class), cobwebs, leatherleaf slugs(Vaginula bleekeri).Key words: Kubu Raya, Mangrove, Pagodiella spp., PT.

This study uses the two largest available American English language corpora, Google Books and the Corpus of Historical American English (coha), to investigate relations between ecology and language. The paper introduces ecolinguistics as a promising theme for corpus research. While some previous ecolinguistic research has used corpus approaches, there is a case to be made for quantitative methods that draw on larger datasets. Building on other corpus studies that have made connections between language use and environmental change, this paper investigates whether linguistic references to other species have changed in the past two centuries and, if so, how. The methodology consists of two main parts: an examination of the frequency of common names of species followed by aspect-level sentiment analysis of concordance lines. Results point to both opportunities and challenges associated with applying corpus methods to ecolinguistc research.
