Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

The Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Osteometry of Duck Species in Northwestern Europe—A Reassessment of Woelfle's (1967) Dataset

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT This study revisits and expands upon Elisabeth Woelfle's (1967) foundational analysis of bone morphology and osteometry, which has long been a key reference for zooarcheological identification of duck species in northwestern Europe. By examining Woelfle's unpublished measuring protocols and incorporating 523 newly measured specimens, we ...

Efficient Masked Autoencoder for Birdsong Representation with Applications on Wild Bird Species Classification

Integrative Zoology, EarlyView.
Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...

New perspectives on head and neck allometry and ecomorphology in tetrapods

Biological Reviews, EarlyView.
ABSTRACT The skull and neck are vital parts of the body, influencing feeding ecology, habitat exploitation and locomotion. Numerous studies have therefore sought to understand how the size of these segments vary with ecology and scale with overall body size.

Sexually dichromatic hybrids between two monochromatic duck species, the Chiloé wigeon and the Philippine duck

Ecology and Evolution, 2021
Captive bird hybrids can provide important data on certain traits, such as hybrid viability and fertility. In this paper, we describe four hybrids between the Chiloé wigeon (Anas sibilatrix) and the Philippine duck (Anas luzonica).

On the heritability of geographic range sizes [PDF]

, 2003
Within taxonomic groups, most species are restricted in their geographic range sizes, with only a few being widespread. The possibility that species-level selection on range sizes contributes to the characteristic form of such speciesrange size ...
