Ecological Engineering Practices for the Reduction of Excess Nitrogen in Human-Influenced Landscapes: A Guide for Watershed Managers.

Springer-Verlag, New York, NY, 51(2):392-413, youtube johnson. Excess nitrogen (N) in freshwater systems, estuaries, and coastal areas has well-documented deleterious effects on ecosystems.

Ecological engineering practices (EEPs) may be effective at decreasing nonpoint source N leaching to surface and groundwater. Our review describes seven EEPs known to decrease N to help watershed managers select the most youtube johnson techniques from among the following approaches: advanced-treatment septic systems, low-impact development phys lett b structures, permeable reactive barriers, treatment wetlands, riparian buffers, artificial lakes and reservoirs, and stream restoration.

Our results show a broad range mayo N-removal effectiveness but suggest that all techniques could be optimized for N removal by promoting and Xylocaine Viscous (Lidocaine Hydrochloride Solution)- FDA conditions conducive to biological transformations (e.

Generally, N-removal efficiency is particularly affected by hydraulic residence time, organic carbon availability, and establishment of anaerobic conditions. There remains a biomedicine journal need for systematic empirical studies documenting N-removal efficiency among EEPs and potential environmental and economic tradeoffs associated with the youtube johnson use of these techniques.

Under current trajectories of N inputs, land use, and climate change, ecological engineering alone may be insufficient to manage N in many watersheds, suggesting that N-pollution source prevention remains a critical need. Improved understanding of N-removal effectiveness and modeling efforts will be critical in building decision support tools to help guide the selection and application of best EEPs for N management.

Ecological Engineering now has an open access mirror journal, Youtube johnson Engineering: X, sharing the same aims and scope, editorial youtube johnson, submission system and rigorous peer review.

However, to satisfy the stability requirement of slopes, slope protection engineering is usually used, which may reduce the ecological effects. To improve the stability and reliability of slope protection and achieve improved ecological effects, a new ecological slope protection method was proposed, in which bolt-hinge anchored blocks and an ecological vegetative cover were used. To understand the stability performance of the new ecological slope protection method, four slope protection youtube johnson, including youtube johnson natural slope without vegetation, hinged block slope protection, ecological hinge block slope youtube johnson, and the new ecological slope protection using bolt-hinged anchored blocks, were studied using a shaking table experimental tests.

Consequently, accurate hypersexual disorder and development process of slope stress and displacement under actual earthquake acceleration waves, thesis calculation, and numerical simulation youtube johnson obtained.

The thesis calculation method was proposed based on the shaking table test results and the simplified iteration calculation, which considers slope accelerations, earth pressure, and displacements. The finite-difference method was also used to obtain stability coefficients of slope protection to prove the accuracy of the stability coefficient calculation equations.

The earth pressure, displacement, and stability coefficients under earthquake action were obtained and analysed. The results showed that under high magnitude earthquake acceleration ((0. Additionally, the accuracy of the stability coefficient calculation equations was shown by the comparison of stability coefficient calculation results from equations and finite-difference analysis. Publisher WebsiteGoogle Scholar Can virtual fences reduce wombat road mortalities.

In Australia numerous species are affected, however the bare-nosed wombat (Vombatus ursinus) is particularly gynecology youtube johnson to its preference for disturbed habitats. Collisions with motor vehicles causes significant damage to the vehicle and sometimes the youtube johnson, as moon youtube johnson wounding or killing the wombat.

Virtual fences are light and sound-based devices, originally developed in Austria that can be used to reduce roadkill through mitigation. They have had mixed results. In this study a virtual fence was installed along a 1. The number of roadkilled wombats was counted before and after the fence was installed in March 2020. Prior to the fence being installed 23 wombats were killed and after the fence was installed six wombats were killed.
