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

open access: yesInternational 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 ...

Assessing relative hazard, risk, and seasonal differences of wildlife‐aircraft collisions

open access: yesWildlife Society Bulletin, Volume 49, Issue 3, September 2025.
Wildlife collisions with aircraft have occurred since the inception of aviation, with significant safety and economic implications. Strike risk models are used to assess the probability of an adverse event between wildlife and aircraft, providing information to guide wildlife management at airports. This study builds upon DeVault et al.

Fearfulness of geese and swans on cropland in winter: a multi‐species flight initiation distance approach

open access: yesWildlife Biology, Volume 2025, Issue 4, July 2025.
Geese and swans are focal species in conservation and in management aimed at reducing crop damage. In the former disturbance should be minimized, and in the latter it is important to know how different species react to scaring activities. Previous research about trade‐off between predation risk and foraging in birds often uses ‘flight initiation ...

Management Implications of Molt Migration by the Atlantic Flyway Resident Population of Canada Geese, Branta canadensis [PDF]

open access: yes, 2007
We used satellite-tracked transmitters in 2001 and 2003 to document the timing, location, and extent of molt migrations by female Canada Geese (Branta canadensis) affiliated with the Atlantic Flyway Resident Population (AFRP) of Canada Geese that breed ...

Abundance and reproduction behavior data for waterbirds (Anatidae, Rallidae, Charadriiforms, Podicipediforms) breeding in European France based on a probability sampling design

open access: yesEcological Research, Volume 40, Issue 4, Page 631-643, July 2025.
In this paper, we provide the dataset issued from field surveys of 2428 grid cells of 500 m × 500 m in French wetlands during springs 2021 and 2022. Such cells resulted from a stratified two‐stage sampling design. The 132,292 birds recorded in this study, together with their reproduction behavior, will be used to evaluate national breeding population ...

Risk posed by the HPAI virus H5N1, Eurasian lineage goose/Guangdong clade 2.3.4.4b. genotype B3.13, currently circulating in the US

open access: yesEFSA Journal, Volume 23, Issue 7, July 2025.
Abstract The emergence of highly pathogenic avian influenza (HPAI) A(H5N1), clade 2.3.4.4b, genotype B3.13 in U.S. dairy cattle marks a significant shift in the virus' host range and epidemiological profile. Infected cattle typically exhibit mild clinical signs, such as reduced milk production, mastitis and fever, with morbidity generally below 20% and

Examining inter‐regional and intra‐seasonal differences in wintering waterfowl landscape associations among Pacific and Atlantic flyways

open access: yesJournal of Avian Biology, Volume 2025, Issue 3, May 2025.
The Central Valley of California (CVC) and Mid‐Atlantic (MA) in the U.S. are both critical sites for nationwide food security, and many waterfowl species annually, especially during the winter, providing feeding and roosting locations for a variety of species.

Geo-Tag der Artenvielfalt, 06. und 07.06.2009: Harpener Teiche und Umgebung in Bochum [PDF]

open access: yes, 2012
Das Untersuchungsgebiet wurde ausgewählt, da die Harpener Teiche eine lokale Kuriosität darstellen. Sie wurden einst als Klärteiche für die Bergbauabwässer der nahegelegenen Zeche Robert Müser genutzt. Heute dient der Schacht der zentralen Wasserhaltung.
