Disentangling conservation asymmetries through socio‐economic transboundary factors across the Alto Paraná Atlantic Forest of South America

People and Nature, EarlyView.
Abstract Ecoregions are often defined based on homogeneous biophysical and ecological conditions and are optimal spatial units for designing conservation strategies. However, transboundary ecoregions such as the Alto Paraná Atlantic Forest (APAF) experience asymmetrical conservation outcomes, understood here as cross‐border differences, resulting from ...

Permafrost Terrain Disturbance Susceptibility in the Nacho Nyäk Tagé (Stewart River) Watershed, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The Nacho Nyäk Tagé (Stewart River) watershed in central Yukon (Canada) is characterized by discontinuous permafrost that is locally highly sensitive to thaw. This study aims to map the spatial distribution of permafrost terrain disturbances (PTDs) in the watershed and model thaw susceptibility to support community‐led land‐use planning by the

A comparative analysis revealing incongruence in the impacts of small and large hydroelectric power plants on fish communities [PDF]

Neotropical Ichthyology
Hydroelectric power plants significantly alter freshwater ecosystems, yet the differences in impacts between small hydroelectric power plants (SHPs) and large hydroelectric power plants (LHPs) on fish assemblages remain poorly understood.

Dam It, I’m Stranded: Evaluating Fish Stranding Downstream of Two Hydropeaking Dams in Northern Ontario

River Research and Applications, EarlyView.
ABSTRACT Globally, there has been an increase in the development and use of hydropower to produce energy. Hydropeaking is an operating regime that is used to meet real‐time energy demands; however, daily fluctuations in flows may result in fish becoming stranded.
