Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Restoring Lateral Connectivity to Anthropogenic Riverscapes: Six Lessons From Stage Zero

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Centuries of river modification, particularly straightening and incision, have severely reduced lateral connectivity between rivers and their floodplains. As a result, Stage 0 riverscapes, characterised by high lateral connectivity (e.g., anastomosing or wetland riverscapes), are now rare in anthropogenic landscapes.

Forensic Hydraulic Analysis of Floodplain Connectivity Driven by Historical Beaver Dams in Colorado Headwater Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

Multi‐Platform Deployments of Low‐Cost Devices for Cetacean Passive Acoustic Monitoring

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Recent advances in affordable, user‐friendly devices offer new opportunities to overcome cost constraints of underwater passive acoustic monitoring (PAM) and expand acoustic data collection. In this study, we deployed low‐cost acoustic recorders and underwater cameras across a range of platforms in the Western Mediterranean, including fishing gear ...

Ecological dams: Concept, transformation, and developmental pathways of dam projects under the framework of river ethics

open access: yesRiver, EarlyView.
This figure elaborates the scientific connotation and systematic construction path of ecological dams. Adopting a full‐cycle analysis framework centered on ecological impacts and benefits throughout the project lifecycle, it covers four key stages from planning to post‐completion, with core focuses on risk avoidance, impact control, ecological health ...

Who Does Bogotá “Care” for? Care Blocks, Care Workers and the Sustainable Development Goals

open access: yesSustainable Development, EarlyView.
ABSTRACT This paper critically examines Bogotá's District Care System within the framework of urban social sustainability and the Sustainable Development Goals (SDGs). Focusing on the Care Blocks (Manzanas del Cuidado), it employs a mixed‐methods approach—legal analysis, interviews, testimonies, surveys, and InfoCuidado data—to explore the paradox of a

Estimation of the Recreational Use Value Gained from Recreational Fishing of Southern Bluefin Tuna at Portland, Australia

open access: yes
Southern bluefin tuna (Thunnus Maccoyii) is a global resource which is critically endangered. The Committee for the Conservation of Southern Bluefin Tuna (CCSBT) sets commercial quota levels for member nations, including Australia, each year.
