All the bedrooms a stage: Reconceptualizing sex as “performance” to sex as “rehearsal”

open access: yesFeminist Anthropology, EarlyView.
Abstract In the United States, sex is often spoken about in terms of performance, and naturally invokes language of theatricality. Sexual performance has been used as an umbrella term to refer to sexual satisfaction, behavior, embodiment, and also pathology in terms of conditions such as erectile dysfunction.

Evaluating the Air Respiratory Capacity of Awaous (Chonophorus) tajasica (Gobiiformes: Oxudercidae): A Morpho‐Functional Study

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
We demonstrated that Awaous tajasica performs facultative air breathing under experimental conditions of dissolved oxygen limitation, retaining air bubbles in the buccal cavity during gill ventilation. Morpho‐functional evidence indicates the use of atmospheric oxygen as a respiratory support under conditions of low water oxygenation.
