Sustainable Development

14.3K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Osmoregulation in Fishes

52.0K
When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

Keystone Species01:39

Keystone Species

23.3K
Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a...

Bioremediation

21.7K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Conservation of Mass in Moving, Nondeforming Control Volume

1.2K
Stormwater detention basins are essential in managing runoff during heavy rainfall, particularly in urban areas where impervious surfaces increase the risk of flooding. Understanding the conservation of mass in these systems allows engineers to optimize basin performance, balancing inflow, outflow, and water storage.
In the context of a detention basin, the conservation of mass states that the total mass of water entering the basin must equal the mass leaving the basin plus any accumulation of...

Summary
This summary is machine-generated.

Estuary management can improve by focusing on ecosystem functions beneficial to humans. A functional equivalency (FE) approach, adapted from fisheries, provides a framework for assessing and maintaining these vital ecosystem services.

Area of Science:

  • Environmental Science
  • Ecosystem Management
  • Conservation Biology

Background:

  • Estuary management faces challenges due to conflicting objectives and a lack of consensus on operational tools.
  • Current management often addresses individual problems rather than focusing on maintaining overall ecosystem functions.
  • Maintaining ecosystem functions is crucial for ensuring ecological health and human benefits.

Purpose of the Study:

  • To propose and demonstrate an adaptation of the functional equivalency (FE) assessment approach for estuary management.
  • To integrate the FE approach into existing ecosystem assessment tools.
  • To foster discussion on enhancing science-policy integration for effective estuary management.

Main Methods:

  • Adapted the functional equivalency (FE) assessment approach from marine fishery management.
  • Developed a three-component framework: target ecosystem functions, measurable metrics, and policy-based thresholds.
  • Applied the framework using a case study with available data, models, and management policies.

Main Results:

  • Demonstrated the practical application of the FE framework in an estuary case study.
  • Highlighted the components necessary for implementing the FE approach: defining functions, metrics, and thresholds.
  • Showcased how available data and models can be utilized within the FE framework.

Conclusions:

  • The functional equivalency (FE) approach offers a structured method for estuary management focused on ecosystem functions.
  • Successful implementation requires high data availability and strong integration between scientific research and policy-making.
  • Adopting the FE approach can lead to more integrated and effective estuary management strategies focused on human-beneficial functions.
