A study has found that ants are responsible for moving more than half of food resources from the rainforest floor, playing a key role in maintaining a healthy ecosystem.
Soil compaction is a global threat to soil ecosystem services, causing tremendous costs to society. The costs of soil compaction are borne by the cumulative loss of soil functionality (e.g. yield loss) following a compaction event until the soil has functionally recovered. Although soil compaction is relatively widely studied, there is a lack of reliable observations and metrics for soil structure recovery rates after compaction.
Currently, agriculture accounts for approximately 9% of total US greenhouse gas (GHG) emissions. By varying diet formulation and the associated crop production to supply the diet, farmers can affect the quantity of GHG emissions of various feeding systems. Therefore, researchers have created a study to compare the effects of feeding strategies and the associated crop hectares on GHG emissions of Wisconsin certified organic dairy farms.
Five years ago, a highly publicized meta-analysis of more than 200 studies concluded that organic food was no more nutritious than conventionally grown food. Since then, however, additional work has suggested the organic foods contain more health-benefiting phytochemicals. Now, researchers have found that flavonoid levels and antioxidant activity in organic onions are higher than in conventional onions. Their investigation is the longest-running study to address the issue.
