Lamprey and Oyster River Watersheds River Stewardship Program [PDF]

open access: yes, 2002
This project was designed for riverfront landowners and local land use decisionmakers to fill a critical gap in shoreland protection: land management by individual riparian landowners. By working directly with individuals in a hands-on venue, we intended

Unveiling Global Diversity of Patescibacteriota and Functional Interactions with Host Microbes

open access: yesAdvanced Science, EarlyView.
Patescibacteriota represents a diverse group of ultra‐small epibiotic bacteria, which is largely overlooked. By integrating ribosomal protein S3‐based community profiling with MAG‐based metabolic potential analyses, this study provides new insights into their distribution, diversity, and potential interactions with other bacteria across diverse ...

Effects of Human Choices on Characteristics of Urban Ecosystems [PDF]

open access: yes, 2007
Most urban ecology in cities remains an ecology in cities rather than an ecology of cities. Accomplishing the latter requires the inclusion of humans within the concept of ecosystem, both how humans alter the properties of urban ecosystems and how ...

Remote Modulation of Single‐Atom Catalyst Boosts High‐Valent Cobalt–Oxo Species Generation for Water Purification and Detoxification

open access: yesAdvanced Science, EarlyView.
This study develops a phosphorus‐doped cobalt single‐atom catalyst that enhances high‐valent cobalt–oxo species generation for water purification. This atomic‐level tuning boosts the catalyst's activity by 3.5 times, enabling efficient pollutant degradation. A continuous‐flow reactor achieves high, long‐term removal efficiency, producing water with low

Plant Robotics for Sustainable and Environmentally Friendly Robots: Insights from Actuation Characteristics

open access: yesAdvanced Science, EarlyView.
Plants are promising materials for building sustainable and eco‐friendly robots due to their inherent multifunctionality, with actuation playing a crucial role. This article focuses on the physical movements of plants and, from the perspective of actuation characteristics, explores representative plant species and their behaviors, the current state of ...

Urban Ecology in Cape Town: South African Comparisons and Reflections

open access: yesEcology and Society, 2012
Little urban ecological research has been done in South Africa. The papers in the Ecology and Society special feature Urban Ecological and Social-Ecological Research in the City of Cape Town make, therefore, an important contribution to the development

Urbanization and health in Africa : exploring the interconnections between poverty, inequality and the burden of disease [PDF]

open access: yes, 2005
There are few changes in the history of human existence comparable to urbanization in scope and potential to bring about biologic change. The transition in the developed world from an agricultural to an industrial-urban society has already produced ...
