The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

open access: yesBiological Reviews, EarlyView.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Anatomical and biomechanical traits of broiler chickens across ontogeny. Part II. Body segment inertial properties and muscle architecture of the pelvic limb [PDF]

open access: yes, 2014
In broiler chickens, genetic success for desired production traits is often shadowed by welfare concerns related to musculoskeletal health. Whilst these concerns are clear, a viable solution is still elusive.

TRANSMISSIBLE ENTERITIS IN YOUNG GUINEA FOWL [PDF]

open access: yesAnnales de Zootechnie, 1975
This disease occurring in intensive rearing conditions causes the death of young birds between the jth and the 28th day of age. The highest mortality is between the 5th and the 15 th day of age. It is characterized by enteritis and nephritis. On the crop of young animals it is possible to see, in some clinical observations typical candidosis lesions. A

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Macroscopic embryonic development of Guinea fowl compared to other domestic bird species

open access: yesRevista Brasileira de Zootecnia, 2019
Since few studies have addressed the embryonic development of Guinea fowl (Numida meleagris), the objective of the present study was to evaluate its embryonic development in the Cerrado region of Brazil and compare the results to published descriptions ...

Swing-leg trajectory of running guinea fowl suggests task-level priority of force regulation rather than disturbance rejection. [PDF]

open access: yesPLoS ONE, 2014
To achieve robust and stable legged locomotion in uneven terrain, animals must effectively coordinate limb swing and stance phases, which involve distinct yet coupled dynamics.

Myopia Development and Control: An Integrative Review of Genetic, Optical, and Environmental Mechanisms With Implications for Personalized Intervention

open access: yesEye &ENT Research, EarlyView.
ABSTRACT Myopia is a rapidly growing global health challenge, affecting 1.9 billion people and projected to reach 4.9 billion by 2050, with high myopia and its sight‐threatening complications such as maculopathy, retinal detachment, and glaucoma increasing disproportionately.

Tuning of feedforward control enables stable muscle force-length dynamics after loss of autogenic proprioceptive feedback

open access: yeseLife, 2020
Animals must integrate feedforward, feedback and intrinsic mechanical control mechanisms to maintain stable locomotion. Recent studies of guinea fowl (Numida meleagris) revealed that the distal leg muscles rapidly modulate force and work output to ...

Waves of genomic hitchhikers shed light on the evolution of gamebirds (Aves: Galliformes) : research article [PDF]

open access: yes, 2007
Background The phylogenetic tree of Galliformes (gamebirds, including megapodes, currassows, guinea fowl, New and Old World quails, chicken, pheasants, grouse, and turkeys) has been considerably remodeled over the last decades as new data and analytical ...
