Global patterns and predictors of avian population density

open access: yesGlobal Ecology and Biogeography, Volume 32, Issue 7, Page 1189-1204, July 2023., 2023
Abstract Aim How population density varies across animal species in the context of environmental gradients, and associated migratory strategies, remains poorly understood. The recent influx of avian trait data and population density estimates allows these patterns to be described and explored in unprecedented detail.

Bird genetic databases need improved curation and error reporting to NCBI

open access: yesIbis, Volume 165, Issue 2, Page 472-481, April 2023., 2023
The ongoing biodiversity crisis is causing rapid species losses faster than taxonomists' capacity to describe new species. Integrative taxonomic approaches need robust taxonomic baseline data to correctly describe and conserve global species diversity, in which genetic data are one of the pillars.

A survey of the uncinate bone and other poorly known ossicles associated with the lacrimal/ectethmoid complex of the avian skull

open access: yesThe Anatomical Record, Volume 305, Issue 9, Page 2312-2330, September 2022., 2022
Abstract In several taxa of Neornithes (crown group birds), the lacrimal/ectethmoid complex exhibits small bones, the comparative osteology of which is poorly studied. Some of these ossicles—which are commonly known as uncinate bones (ossa uncinata or ossa lacrimopalatina)—were already described two centuries ago, but knowledge of their distribution ...

Co‐infections: Simultaneous detections of West Nile virus and Usutu virus in birds from Germany

open access: yesTransboundary and Emerging Diseases, Volume 69, Issue 2, Page 776-792, March 2022., 2022
Abstract The emergence of West Nile virus (WNV) and Usutu virus (USUV) in Europe resulted in significant outbreaks leading to avifauna mortality and human infections. Both viruses have overlapping geographical, host and vector ranges, and are often co‐circulating in Europe.

The eggshell structure in apteryx; form, function, and adaptation

open access: yesEcology and Evolution, Volume 11, Issue 7, Page 3184-3202, April 2021., 2021
Apteryx incubates its eggs for 74 days in a ground burrow. The eggshell structure reveals adaptations to this type of environment, and in relation to the climate, the eggshell has been laid in. Abstract Apteryx is a genus of flightless birds endemic to New Zealand known to lay very large eggs in proportion to body weight.
