Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

The Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

The Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Lenticular Autofluorescence in Normal Tree Shrews

Ophthalmic Research, 2009
Lenticular autofluorescence was measured in vivo in 25 normal tree shrews using a fluorophotometer with a specially designed small animal adapter to assess the usefulness of this model of lens pathology. The average variability in the lenticular autofluorescence measurements was 8.7%.

Effects of Gradient Photoperiod and Temperature on Energy Metabolism and Body Composition in Tupaia belangeri chinensis [PDF]

Journal of Stress Physiology & Biochemistry, 2013
In order to explore the adaptive changes in energy metabolism and body composition in response to a gradual reduction in both ambient temperature and photoperiod, male adult tree shrews Tupaia belangeri chinensis were raised under the conditions of 30 oC

RNA-Sequence Reveals the Regulatory Mechanism of miR-149 on Osteoblast Skeleton under Mechanical Tension

Stem Cells International, 2022
Objective. Based on RNA-sequencing (RNA-seq), the regulation of miRNAs differentially expressed in dental, periodontal, and alveolar bone tissue of orthodontic tree shrews on osteoblast skeleton under tension was investigated. Methods.

Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

Biological Reviews, EarlyView.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Optimizing procedures for ocular radiation injury studies in the tree shrew [PDF]

Exploration of Targeted Anti-tumor Therapy
Radiation exposure to the eye during cancer treatment can lead to ocular radiation injury (ORI), a devastating condition that can have a profound and permanent impact on vision-related quality of life. Rodent models do not have adequate ocular anatomy to

Wild meat consumption in changing rural landscapes of Indonesian Borneo

People and Nature, EarlyView.
Abstract Wild meat can play a crucial role in the food system of rural communities residing near tropical forests. Yet, socio‐ecological changes across tropical landscapes are impacting the patterns and sustainability of meat consumption. To understand the prevalence, frequency and drivers of wild meat, domestic meat and fish consumption in this ...
