Beyond the Edge: Linking Agricultural Landscapes, Stream Networks, and Best Management Practices
Journal of Environmental Quality
|February 8, 2018
Summary
Managing agricultural and riverine landscapes separately causes nutrient runoff. Integrating these landscapes with a new framework, including best management practices (BMPs) in river channels, can improve nutrient reduction and ecosystem resilience.
Area of Science:
- Environmental Science
- Ecosystem Management
- Hydrology
Background:
- Nutrient runoff from agricultural landscapes to freshwater ecosystems remains a significant environmental concern.
- Current management strategies often treat agricultural and riverine landscapes separately, creating a disconnect in research and practice.
- Existing interdisciplinary research faces challenges in integrating diverse knowledge areas.
Purpose of the Study:
- To present a novel framework for the integrated study and management of agricultural and riverine landscapes.
- To address the disconnect between watershed surface and river network management.
- To enhance nutrient reduction strategies in agricultural catchments.
Main Methods:
- Development of a conceptual framework integrating ecosystem approaches, resilience thinking, and strategic adaptive management.
- Application of the framework to a case study in the Fox Basin, Wisconsin, USA.
- Analysis of the spatial context of best management practices (BMPs) within the combined watershed-stream network.
Main Results:
- The proposed framework facilitates a cohesive approach to studying and managing combined agricultural and riverine landscapes.
- Targeted placement of BMPs, including within river channels, is crucial for effective nutrient reduction.
- Integrating BMPs enhances the buffering capacity and resilience of the riverine system to nutrient pollution.
Conclusions:
- A unified approach to managing agricultural and riverine landscapes is essential for mitigating nutrient runoff.
- Strategic placement of BMPs across the entire watershed-stream network, not just on agricultural surfaces, is key to improving water quality.
- The framework provides a pathway to increase ecosystem resilience to nutrient pollution and other disturbances.

In two-dimensional incompressible fluid flow, the continuity equation is essential for ensuring mass conservation, meaning that any change in fluid entering or exiting a region is balanced by a corresponding change elsewhere. For incompressible flow, where density remains constant, this requirement simplifies to the condition that the divergence of the velocity field must be zero. Mathematically, this is expressed as,

02:26Protein Networks
4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

01:19X-linked Traits
59.0K
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.
