“Lovelies on Wheels”: The Politics of Miss Wheelchair America, 1972–1977

open access: yesGender &History, EarlyView.
ABSTRACT This article examines the Miss Wheelchair America pageant in the 1970s as a cultural and political space that produced a specific message about the intersections of womanhood, disability, and citizenship. The pageant elevated contestants who performed normative femininity, beauty, heterosexuality, and whiteness, while narratively framing ...

Geological Substrate Is Related to Tooth Senescence and Population Dynamic: The Case Study of Alpine Chamois (Rupicapra rupicapra L.)

open access: yesIntegrative Zoology, EarlyView.
In Alpine chamois, the complete wear of the first molar coincides with the beginning of senescence and the progress of tooth wear on calcareous substrate is slower than the one on other substrates, increasing life expectancy. Thus, the first molar wear may actually be considered as an effective descriptor of senescence stage.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

open access: yesIntegrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

An efficient Bayesian phylogenetic approach for joint inference of continuous and discrete trait evolution under a state‐dependent Ornstein–Uhlenbeck model

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Macroevolutionary adaptation of a continuous trait to different discrete states across species can be modelled using a phylogenetic state‐dependent Ornstein–Uhlenbeck (OU) process. Existing inference methods face two challenges. First, although efficient likelihood algorithms for continuous trait evolution models exist, none have been ...
