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

River 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 ...

The Integration of Fire Ecology and Freshwater Ecosystems in North America: Knowledge Gaps and Research Needs. [PDF]

Glob Chang Biol
Illustration of key knowledge gaps and pathways linking fire ecology and freshwater ecosystems. Climate change provides the overarching context, interacting with cumulative and cross‐scale effects to shape local freshwater conditions. Within this context, fire characteristics influence three primary pathways within freshwater ecosystems: species and ...

Using a live‐streaming webcam to assess the behavioural responses of waterbirds to changes in the density of swans Cygnus spp.

Wildlife Biology, EarlyView.
Wildlife research has benefitted from the development of new methods that allow data to be collected remotely, with less disturbance to focal animals. The proliferation of livestreaming webcams, for example, those used by nature reserves for public engagement purposes, have offered new possibilities for the study of wildlife behaviour.

Feathers and flu: identifying data gaps in avian influenza host dynamics to prioritize wildlife conservation Plumas y gripe: identificación de datos faltantes en la dinámica de hospedadores de la influenza aviar para priorizar la conservación de la vida silvestre

Wildlife Monographs, EarlyView.
We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

Journal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Ecological aesthetic assessment of a rebuilt wetland restored from farmland and management implications for National Wetland Parks.

PLoS ONE, 2019
While wetlands are usually used as a natural approach to remove biodegradable pollutants in surface water, their purification efficiencies coupled with their aesthetic features are of less concern. The water quality, plant landscape, acoustic environment

Investigation of Antioxidant Potential of the Ethanolic Extract from Nelumbo Nucifera by Immersion and Ultrasound-assisted Extraction Techniques [PDF]

Research and Innovation in Food Science and Technology
Bioactive compounds such as antioxidants play a fundamental role in human health and nutrition. Furthermore, aquatic plants are considered a valuable and appropriate resource of antioxidants.

Comparative Efficiency of eDNA, Camera Traps and Scat Surveys to Detect a Semi‐Aquatic Mammal Across Multiple Catchments

Animal Conservation, EarlyView.
Monitoring semi‐aquatic mammals is essential for their conservation, but it is made difficult by their elusive lifestyle and generally low abundance. Eurasian otter (Lutra lutra) monitoring has traditionally relied on scat surveys, but eDNA and camera‐trapping are emerging as promising alternatives.

Tropical and subtropical wetland plant species used for phytoremediation in treatment wetlands

, 2023
The high diversity of aquatic and wetland plants in tropical and subtropical regions of the world provides great potential for uses in phytoremediation techniques, ecotoxicological studies, and biomonitoring programs. Phytoremediation refers to pollutant
