Spatial assessment and mapping of soil quality index for desertification in the semi-arid terrestrial ecosystem using MCDM in interval type-2 fuzzy environment

Computers and Electronics in Agriculture, 2019
Land degradation is a significant phenomenon on the world particularly arid, semi-arid and semi-humid terrestrial ecosystem environments due to variety of factors such as through unsustainable land management, and through physical and climatic ...

The Transport of Plutonium in Terrestrial Ecosystems

Health Physics, 1981
Abstract Abstract-Data from several field studies of plutonium were evaluated to identify environmental factors that result in redistribution of this element within ecosystems. When released to terrestrial ecosystems, plutonium is almost quantitively transferred to and retained by soils.

Approaches to Study Terrestrial Ecosystems

2018
In this chapter, different approaches to the study of terrestrial ecosystems are introduced. The chapter is organised in two main parts: observations and experiments. For both of these general approaches, many examples are given from around the globe, introduced by typical research questions and illustrated with photos.

Calorespirometry of terrestrial organisms and ecosystems

Methods, 2015
Calorespirometry is the simultaneous measurement of heat and gas exchange from biological systems. Such measurements can be used to assess fundamental properties of many different types of systems from small ecosystems to isolated tissues. Techniques for calorespirometric measurements on terrestrial (non-aquatic) samples are described.

Global Change and Terrestrial Ecosystems

2018
In this chapter, global change and its impacts on terrestrial ecosystems are discussed. First, land use and land-use change are introduced, focusing on agriculture and forestry, in terms of both their characteristics and their consequences for the biogeochemistry of terrestrial managed ecosystems.

Microplastic in Terrestrial Ecosystems and the Soil?

Environmental Science & Technology, 2012
W live in a “plastic age” with more than 240 million tons of plastic used annually, the majority of which for disposable use. Due to limited recovery of discarded materials and its durability, plastic debris is accumulating in the environment. Recently, research on environmental impacts of plastic has acquired a new dimension through the discovery and ...

Biogeochemical Fluxes in Terrestrial Ecosystems

2018
In this chapter, the major biogeochemical fluxes in terrestrial ecosystems are presented: water, carbon, nitrogen and cation fluxes. The relevance and interactions of all these fluxes are explained, and then their special features discussed, with an additional focus on land management.

Radionuclides in natural terrestrial ecosystems

Science of The Total Environment, 1984
p6osystems to be found in the maritime temperate zone are described. The part played by vegetation, animals and soils in the distribution and movement of radionuclides is discussed, with particular reference to natural systems. Biomass activities have been compiled for 137Cs and 239 + 240Pu in woodland and moorland ecosystems.

Impacts on Terrestrial Ecosystems

2001
The impacts of transport on terrestrial ecosystems can be broadly divided into three different categories: Effects on the physical structure of the landscape, such as direct loss of land and habitat fragmentation, of the land used solely for transport Effects of management of the transport route and adjacent land, including cutting and ...
