Can sexual selection drive female life histories? A comparative study on Galliform birds [PDF]

, 2007
Sexual selection is an important driver of many of the most spectacular morphological traits that we find in the animal kingdom (for example see Andersson, 1994). As such, sexual selection is most often emphasized as

Quantitative proteomics identifies clusterin as a novel biomarker for atherosclerosis

Animal Models and Experimental Medicine, EarlyView.
This schematic illustrates the proposed mechanism. In advanced atherosclerotic lesions, upregulated CLU on the cell surface activates low‐density lipoprotein (LDL) receptor‐related protein 1 (LRP1). This interaction triggers the phosphorylation and activation of AKT.

Sex‐Specific Genetic Architecture of ALS: Evidence of a Female Protective Effect?

Annals of Neurology, EarlyView.
Background Amyotrophic lateral sclerosis (ALS) shows sex differences in incidence and age of onset, yet the underlying biological mechanisms remain poorly understood. Methods We investigated sex‐specific genetic architecture in an Italian ALS cohort with whole‐genome sequencing (1,333 ALS cases, 755 controls).

Homo Sapiens: Are We a Monogamous Species? [PDF]

, 2003
In order for the process of hominization to continue, with its prolonged and extreme period of juvenile defencelessness, it was necessary, or at least convenient, for males to more actively participate in the care of females and offspring. This necessity,

Sexual dimorphism in campylobacteriosis

Epidemiology and Infection, 2007
SUMMARYSexual dimorphism in infectious diseases whereby disease incidence is more prevalent in one gender has been reported repeatedly in the scientific literature. Both behavioural and physiological differences have been suggested as a cause of this gender bias but there is a paucity of data to support either of these viewpoints.

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

The Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

A new Megatheriinae skull (Xenarthra, Tardigrada) from the pliocene of northern venezuela – Implications for a giant sloth dispersal to central and North America [PDF]

, 2018
A skull of a ground sloth from the Pliocene San Gregorio Formation documents a northern neotropical occurrence of a megatheriine that addresses issues on intraspecific variation and biogeography. The new specimen is broadly similar in size and morphology

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

The Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...
