Darwin and evolution: a set of activities based on the evolution of mammals [PDF]

open access: yes, 2010
These activities, prepared for key stage 5 students (ages 16-18) and also suitable for key stage 4 (ages 14-16), show that physical appearance is not necessarily the best way to classify mammals.

Evolution and Biogeography of Haemonchus contortus: Linking Faunal Dynamics in Space and Time [PDF]

open access: yes, 2016
History is the foundation that informs about the nuances of faunal assembly that are essential in understanding the dynamic nature of the host-parasite interface.

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

open access: yesThe Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Characterization of the complete mitogenome of Indian Mouse Deer, Moschiola indica (Artiodactyla: Tragulidae) and its evolutionary significance

open access: yesScientific Reports, 2018
The mitochondrial genome of Indian mouse deer (Moschiola indica) was sequenced, assembled and characterized for the first time using 22 pairs of polymerase chain reaction (PCR) primers. The mitogenome of M.

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 ...

Subsistence harvest for food and pets associated with declining global mammal populations

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Subsistence harvest can have substantial impacts on mammalian biodiversity, yet its effects on the conservation status of mammal species are poorly understood. We analyzed trade and use data in species accounts from the International Union for Conservation of Nature (IUCN) Red List to examine the effects of subsistence harvest on the conservation ...

Why ruminating ungulates chew sloppily: Biomechanics discern a phylogenetic pattern.

open access: yesPLoS ONE, 2019
There is considerable debate regarding whether mandibular morphology in ungulates primarily reflects phylogenetic affinities or adaptation to specific diet.

Phylogenetic Systematics of Peccaries (Tayassuidae: Artiodactyla) and a Classification of South American Tayassuids

open access: yesJournal of mammalian evolution, 2017
Tayassuidae is a family of pig-like Artiodactyla restricted to the New World. Despite its rich fossil history, they have received less attention from a taxonomic and phylogenetic perspective when compared to the Old World pigs, Suidae.

Neo‐Taphonomic Analysis of Prey Bone Remains Accumulated by Golden Eagle (Aquila chrysaetos): A Case of Nests in Southern France

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The golden eagle (Aquila chrysaetos) nests in rock cavities where it accumulates prey bone remains during the breeding season. Because nests can be reoccupied from year to year, these faunal elements can form remarkable bone accumulations and, in the sub‐fossil record, be mixed with assemblages derived from human or other predator activities ...

New Spontaneous Model of Fibrodysplasia Ossificans Progressiva [PDF]

open access: yes, 2008
We report the first known example of spontaneous, naturally occurring fibrodysplasia ossificans progressiva (FOP) in a mammal. The Southeast Asian mouse deer of the genus _Tragulus_ (Artiodactyla: Tragulidae) have an osseous sheath covering the lower ...
