1. Bioclimate envelope models are widely used to predict the potential distribution of species under climate change, but they are conceptually also suitable tomatch policies and practices to anticipated or observed climate change, for example through species choice in reforestation. Projections of bioclimate envelope models, however, come with large uncertainties due to different climate change...

Information about the distribution of grass nitrogen (N) concentration is crucial in understanding rangeland vitality and facilitates effective management of wildlife and livestock. A challenge in estimating grass N concentration using remote sensing in savannah ecosystems is that these areas are characterised by heterogeneity in edaphic, topographic and climatic factors. The objective is to te...

Factors that may account for subarctic vegetation patterns that are not reconcilable with synoptic climate were sought by reference to data on local climate, soils, parent materials, vegetation, and topography. Where the forest-tundra lies climatically northward, the vegetation transition zone is relatively narrow, and the soils are nutrient-rich, fine-textured loamy Cryosols derived from sedim...

The role that mycorrhizal fungal associations play in the assembly of long-lived tree communities is poorly understood, especially in tropical forests, which have the highest tree diversity of any ecosystem. The lowland tropical rain forests of Southeast Asia are characterized by high levels of species richness within the family Dipterocarpaceae, the entirety of which has been shown to form obl...

Nitrification is a key process in soil nitrogen (N) dynamics, but relatively little is known about it in tropical soils. In this study, we examined soils from Trinidad to determine the edaphic drivers affecting nitrification levels and community structure of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) in non-managed soils. The soils were naturally vegetated, ranged in t...

The impact of invasive species on the ecosystems belongs to most important environmental problems. Representatives genus Solidago actively invade various plant communities. About 2300 literary sources were analyzed in order determine main tasks for researchers this and highlight relevant issues. Ambiguous evidence inhibitory effect goldenrod native flora has been observed. Some studies report i...

Bioindicator organisms, such as edaphic invertebrates, are constantly used to assess disturbance, they exhibit responses reduced community and changes in diversity, affecting the local ecosystem. The aim of this study was compare impacts disturbance on invertebrate both a pasture area native forest area, during summer winter. Samplings were conducted for nine days using pitfalls. Bray-Curtis an...
