The relationship of telomere length to baseline corticosterone levels in nestlings of an altricial passerine bird in natural populations. [PDF]

open access: yes, 2016
BackgroundEnvironmental stressors increase the secretion of glucocorticoids that in turn can shorten telomeres via oxidative damage. Modification of telomere length, as a result of adversity faced early in life, can modify an individual's phenotype ...

Metasurfaces and Metadevices for Topological Electromagnetic Waves

open access: yesAdvanced Physics Research, EarlyView.
Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

open access: yesThe Anatomical Record, EarlyView.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

open access: yesThe Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

Natural history contributions of the University of Glasgow Exploration Society to Scotland and the World [PDF]

open access: yes, 2017
Expeditions with a natural history focus have been organised by University of Glasgow staff and students since the 1930s. The educational benefits of such expeditions to students have been reported by Harper et al.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...
