Challenges of measuring body temperatures of free-ranging birds and mammals [PDF]

, 2015
The thermal physiology of most birds and mammals is characterised by considerable spatial and temporal variation in body temperature. Body temperature is, therefore, a key parameter in physiological, behavioural and ecological research.

Double‐crested cormorant distribution on catfish aquaculture in the Yazoo River Basin of Mississippi

Wildlife Society Bulletin, 2012
Estimating the catfish aquaculture production losses that can be attributed to double‐crested cormorants (Phalacrocorax auritus) has proved problematic because knowledge of the distribution of cormorants on catfish aquaculture is lacking.

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 ...

New county records of chewing lice (Mallophaga) on birds in Florida [PDF]

, 2002
County records for avian lice are less significant than the host records themselves. Considering that most avian lice are host specific, the county records should resemble the area the host would most likely be encountered. Nonetheless, the list cited in

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.

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.

Heat increment of feeding in double-crested cormorants (Phalacrocorax auritus) and its potential for thermal substitution [PDF]

Journal of Experimental Biology, 2008
SUMMARYDiving endotherms inhabiting polar regions face potentially high thermoregulatory costs. Unless properly insulated, these animals will lose vast amounts of heat when diving in cold water, which has to be balanced by heat production. Heat generated as a by-product of digestion (heat increment of feeding, HIF) or from exercising muscles might be ...

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.

A Landscape Perspective on Bird Beak Deformity: An Epizootic of Unknown Etiology [PDF]

, 2011
Although birds with beak deformities have been documented throughout the literature, the recent spike in occurrences in certain regions has caused concern in the scientific community.
