Spatial distribution, structural characterization and weathering of tarmats along the west coast of Qatar
(
Elsevier
, 2020 , Article)
Oil pollution resulting from natural and anthropogenic activities in the Arabian Gulf as well as oil residue in the form of tarmat (TM) deposited on the coast is a major environmental concern. The spatial distribution, ...
Quantifying variations in ecosystem services in altitude-associated vegetation types in a tropical region of China
(
Elsevier
, 2020 , Article)
Natural vegetation is important for ecosystem services (ESs) provision, but is decreasing rapidly due to human-driven land use change, especially rapid expansion of commercial plantations. This is leading to a decrease in ...

(
Taylor and Francis
, 2020 , Article)
© 2020 Taylor & Francis Group, LLC. Fourier transform infrared (FTIR) spectroscopy has been extensively used in microplastic (MP) pollution research since 2004. The aim of this review is to discuss and highlight the ...
Legacy effects of experimental environmental change on soil micro-arthropod communities
(
wiley
, 2020 , Article)
© 2020 The Authors. Global change experiments such as experimental warming and nutrient addition strongly affect the structure and functioning of high latitude and altitude ecosystems. However, it is often unknown to what ...
Global plant trait relationships extend to the climatic extremes of the tundra biome
(
Nature Research
, 2020 , Article)
The majority of variation in six traits critical to the growth, survival and reproduction of plant species is thought to be organised along just two dimensions, corresponding to strategies of plant size and resource ...
Faunal mediated carbon export from mangroves in an arid area
(
Elsevier
, 2020 , Article)
The outwelling paradigm argues that mangrove and saltmarsh wetlands export much excess production to downstream marine systems. However, outwelling is difficult to quantify and currently 40–50% of fixed carbon is unaccounted ...

(
Elsevier
, 2020 , Article)
© 2020 The Authors Aims: Litter decomposition is an important driver of soil carbon and nutrient cycling in nutrient-limited Arctic ecosystems. However, climate change is expected to induce changes that directly or indirectly ...
