Interspecific analysis of covariance structure in the masticatory apparatus of galagos.

The primate masticatory apparatus (MA) is a functionally integrated set of features, each of which performs important functions in biting, ingestive, and chewing behaviors. A comparison of morphological covariance structure among species for these MA…

Gait selection and the ontogeny of quadrupedal walking in squirrel monkeys (Saimiri boliviensis).

Locomotor researchers have long known that adult primates employ a unique footfall sequence during walking. Most mammals use lateral sequence (LS) gaits, in which hind foot touchdowns are followed by ipsilateral forefoot touchdowns. In contrast, most…

Neuromuscular anatomy and evolution of the cetacean forelimb.

The forelimb of cetaceans (whales, dolphins, and porpoises) has been radically modified during the limb-to-flipper transition. Extant cetaceans have a soft tissue flipper encasing the manus and acting as a hydrofoil to generate lift. The…

Molar scaling in strepsirrhine primates.

We examined how maxillary molar dimensions change with body and skull size estimates among 54 species of living and subfossil strepsirrhine primates. Strepsirrhine maxillary molar areas tend to scale with negative allometry, or possibly isometry,…

Ontogeny of long bone geometry in capuchin monkeys (Cebus albifrons and Cebus apella): implications for locomotor development and life history.

Studies of a diverse array of animals have found that young individuals often have robust bones for their body size (i.e. augmented cross-sectional dimensions), limiting fracture risk despite general musculoskeletal immaturity. However, previous…

A new zygodactylid species indicates the persistence of stem passerines into the early Oligocene in North America.

BACKGROUND: The lake deposits of the informal Ruby Paper Shale unit, part of the Renova Formation of Montana, have yielded abundant plant fossils that document Late Eocene - Early Oligocene global cooling in western North America. A nearly complete…

Why are some species more commonly afflicted by arthritis than others? A comparative study of spondyloarthropathy in primates and carnivores

Spondyloarthropathy is a painful arthritic affliction of humans that also occurs in wild mammals. Important questions remain concerning the underlying causes of spondyloarthropathy in mammals, particularly regarding whether it is infectious in origin…

Reevaluation of the lumbosacral region of Oreopithecus bambolii

Functional interpretations of the postcranium of the late Miocene ape Oreopithecus bambolii are controversial. The claim that Oreopithecus practiced habitual terrestrial bipedalism is partly based on restored postcranial remains originally recovered…

Temperature regulates limb length in homeotherms by directly modulating cartilage growth

Allen's Rule documents a century-old biological observation that strong positive correlations exist among latitude, ambient temperature, and limb length in mammals. Although genetic selection for thermoregulatory adaptation is frequently presumed to…

AL 288-1 - Lucy or Lucifer: Gender confusion in the Pliocene

Hausler & Schmid (1995) challenged the long held opinion that AL 288-1 (Australopithecus afarensis), popularly known as "Lucy," was female. They concluded that AL 288-1 was most probably male ("Lucifer") and, by extension, the hypodigm for A.…

Does behavioural hypothermia promote post-exercise recovery in cold-submerged frogs?

At the low temperatures of the overwintering environment of the frog Rana temporaria, small changes in ambient temperature have large effects on metabolism and behaviour, especially since Q(10) values are often greatly elevated in the cold. How the…
