Soil biota in grassland, its ecosystem services and the impact of management [PDF]

, 2007
In the search for sustainable grassland systems, self-regulating processes in the soil become increasingly important. Soil biota play an important role in these processes and in the provision of various ecosystem services. For grassland systems important

‘Incoherence Is, in a Way, a Choice’: The Production of Policy Coherence at the Intersection of Uruguay's Agricultural, Environmental and Water Policies

Environmental Policy and Governance, EarlyView.
ABSTRACT This study explores the production of coherence between Uruguay's agricultural, environmental and water policies amidst growing tensions, which are particularly manifested in conflicts between an expanding agricultural sector and water insecurity for the broader public.

Environmental selection overturns the decay relationship of soil prokaryotic community over geographic distance across grassland biotas

eLife, 2022
Though being fundamental to global diversity distribution, little is known about the geographic pattern of soil microorganisms across different biotas on a large scale.

Occurrence and abundance of meso and microplastics in sediment, surface waters, and marine biota from the South Pacific region.

Marine Pollution Bulletin, 2020
Data on the occurrence and abundance of meso and microplastics for the South Pacific are limited and there is urgent need to fill this knowledge gap. The main aim of the study was to apply a rapid screening method, based on the fluorescence tagging of ...

Toxic Metals in Dried Marine Fish and Implications for Human Health in Bangladesh and Exporting Countries

Food Safety and Health, EarlyView.
This study assessed toxic metals in five dried marine fish species from Bangladesh. Although most metals were within safe limits, chromium (Cr) consistently exceeded FAO/WHO standards, especially at Kuakata Beach. The findings highlight localized contamination hotspots and species‐specific bioaccumulation, while risk assessment supports the safety and ...

Does Long-Term Macrophyte Management in Lakes Affect Biotic Richness and Diversity? [PDF]

, 2005
We hypothesize that the richness and diversity of the biota in Lake Moraine (42°50’47”N, 75°31’39”W) in New York have been negatively impacted by 60 years of macrophyte and algae management to control Eurasian watermilfoil ( Myriophyllum spicatum L.

Selecting Promising Soil Quality Indicators for Monitoring Soil Management Effects Based on 10 European Long‐Term Field Experiments

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Soil quality can be measured through soil quality indicators that reflect soil processes. Aim: The aim of this study was to (1) identify a limited set of soil quality indicators that are most sensitive to agricultural soil management and that are widely applicable regardless of pedo‐climatic conditions, and (2) link common ...

A review of the environments, biota, and methods used in microplastics research in South Africa

South African Journal of Science
Microplastics are small plastic materials often defined as those between 5 mm and 0.05 mm in size. Microplastics can have toxicological impacts on various biota, from gut blockages to the transport or leaching of toxicants used in their production or ...
