Robust age estimation of southern sea otters from multiple morphometrics

Ecology and Evolution, 2020
Reliable age estimation is an essential tool to assess the status of wildlife populations and inform successful management. Aging methods, however, are often limited by too few data, skewed demographic representation, and by single or uncertain ...

Tooth Removal in the Leopard Gecko and the de novo Formation of Replacement Teeth

Frontiers in Physiology, 2021
Many reptiles are able to continuously replace their teeth through life, an ability attributed to the existence of epithelial stem cells. Tooth replacement occurs in a spatially and temporally regulated manner, suggesting the involvement of diffusible ...

The diastemas in deciduous dentition: the relationship to the tooth size and the dental arches dimensions [PDF]

, 2001
Tooth size and different arch parameters were studied for influence in the presence or absence of diastemas in the primary dentition. The size of teeth scarcely influences the presence or absence of diastemas, but the dental arch dimensions are closely ...

A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.

Morphological convergence in a Mexican garter snake associated with the ingestion of a novel prey

Ecology and Evolution, 2017
Morphological convergence is expected when organisms which differ in phenotype experience similar functional demands, which lead to similar associations between resource utilization and performance.
