The Anatomical Record, EarlyView.Abstract This study investigated the physiological and morphological adaptations of the liver of the carnivorous fish Pygocentrus nattereri (piranha) in response to seasonal variations (dry and rainy seasons) in the Brazilian Pantanal. The objective was to describe how the liver, a central organ in metabolic regulation, responds to environmental ...

The Anatomical Record, EarlyView.Abstract In a large sample of adult crab‐eating macaques, we quantified sexual dimorphism in size, shape, and covariance across the whole skull and among anatomical regions of the cranium and mandible. All regions showed significant mean sex differences, but the magnitude of size and shape dimorphism varied substantially.

, 2007 Sexual selection often favours sexual size dimorphism (SSD) in body size and fighting structures, since large males with massive weaponry achieve high reproductive success. However, sexual selection may be opposed by natural selection.

The Anatomical Record, EarlyView.Abstract The preauricular sulcus has long been debated as a pelvic feature variably attributed to obstetric stress, ligamentous traction, and broader biomechanical processes. To clarify its determinants, we analyzed 409 adult individuals from three archeological and one early modern skeletal collection from the Iberian Peninsula, integrating graded ...

A case of dimorphic males in Troxochrus scabriculus (Araneae: Linyphiidae), with notes on synonymy
Arachnologische Mitteilungen, 2018 Troxochrus cirrifrons (O. Pickard-Cambridge, 1871) is a junior synonym of Troxochrus scabriculus (Westring, 1851). Moreover, Troxochrus scabriculus is a species with dimorphic males, the nominate form is referred to as T.

Describing shell shape variations and sexual dimorphism of Golden Apple Snail, Pomacea caniculata (Lamarck, 1822) using geometric morphometric analysis [PDF]
, 2017 Pomacea caniculata or Golden Apple Snail (GAS) existed to be a rice pest in the Philippines and in Asia. Likewise, geographic location also contributes its increasing populations thus making it invasive among freshwater habitats and rice field areas ...

The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives
The Anatomical Record, EarlyView.Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,
