Monitoring faunal responses to biodegradable oyster reef restoration materials with camera traps in a subtropical estuary

Restoration Ecology, Volume 33, Issue 8, November 2025.
Oyster reef restoration has become increasingly crucial due to global population declines. Intertidal oyster reefs provide essential foraging and loafing (resting) grounds to estuarine fauna. To reduce plastic pollution from traditional materials, biodegradable restoration materials have been introduced and are shown to support oyster recruitment ...

Marking power lines to reduce avian collisions near the Audubon National Wildlife Refuge, North Dakota

Wildlife Society Bulletin, 2013
Overhead power lines can pose collision risks to birds. Risks may be mitigated through marking lines with high‐visibility devices, but the effectiveness of line marking remains unclear.

Marine Bird Bycatch in Alaska Salmon Gillnet Fisheries

Fisheries Management and Ecology, Volume 32, Issue 5, Page 366-387, October 2025.
ABSTRACT Incidental catch in gillnet fisheries has a substantial conservation impact on marine diving birds. We synthesized available marine bird bycatch data from Alaska salmon gillnet fisheries to estimate standardized bycatch rates, model factors influencing bycatch rates, and estimate total bycatch.

Bone Mineral Density of Willow Ptarmigan (Lagopus lagopus) as a Potential Taphonomic Factor in Skeletal Part Attrition

International Journal of Osteoarchaeology, Volume 35, Issue 5, Page 284-294, September/October 2025.
ABSTRACT Agents of taphonomy can bias skeletal parts and the frequency of bones in archaeological sites. An important factor to consider is the possible effect of bone density‐mediated attrition on archaeornithological assemblages. We scanned willow ptarmigan (Lagopus lagopus) specimens using a Lunar iDXA and an enCcore small animal body add‐on to ...

Sinoatrial Contracaeciasis in Johnny Darters (Etheostoma nigrum) and Plains Topminnow (Fundulus sciadicus) From the South Platte Drainage, Colorado

Aquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT Intra‐sinoatrial nematodes were incidentally recognized in wild‐caught Colorado Johnny Darters (Etheostoma nigrum, JD) in 2020–2021 and in Colorado Plains Topminnow (Fundulus sciadicus, PTM) in 2023‐2024. PTM and JD were evaluated histologically.

Development of methods for avian oil toxicity studies using the double crested cormorant ( Phalacrocorax auritus )

Ecotoxicology and Environmental Safety, 2017
Oral and external dosing methods replicating field exposure were developed using the double crested cormorant (DCCO) to test the toxicity of artificially weathered Deepwater Horizon Mississippi Canyon 252 oil. The majority of previous oil dosing studies conducted on wild-caught birds used gavage methods to dose birds with oil and determine toxicity ...
