Greywater Treatment Using Umbrella Sedge Plants and Activated Carbon Media with Constructed Wetland System

Jurnal Presipitasi
Increased domestic wastewater discharge degrades river quality. This study evaluated phytoremediation using constructed wetlands with umbrella sedge plants to treat greywater prior to river discharge. Using a randomized block design, the study tested two

The Elliot Ditch Constructed Wetlands

Journal of Green Building, 2007
Abstract The purpose of this experiment was to determine the contaminant load reduction incurred using a constructed wetland with an average hydraulic detention time of five days in treating agricultural runoff. The main contaminants present in the runoff were nitrogen and phosphorus from agricultural fertilizers. The findings of the experiment

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age

Journal of Quaternary Science, EarlyView.
ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.

Spatial and temporal variation in survival of female wild turkeys

The Journal of Wildlife Management, EarlyView.
We monitored 370 female wild turkeys across North Carolina's 3 ecoregions from 2020‐2022 to understand factors influencing their survival. Female survival varied by ecoregion and behavior state, with the incubation period having the lowest survival rates. None of the land cover variables affected survival.

Coupling Water Purification and Carbon Sequestration at Various Spatial Scales From Supply and Demand Perspective

Land Degradation &Development, EarlyView.
ABSTRACT Balancing ecosystem‐service supply and demand is central to understanding both the natural and social dimensions of ecosystem services and to enhancing human well‐beings. Concurrently, collaborative efforts are underway to improve multiple ecosystem services, including the promotion of carbon neutrality and water purification (WP) within basin
