Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

open access: yesBiological Reviews, EarlyView.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

open access: yesBiological Reviews, EarlyView.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

An Adaptive Threshold in Mammalian Neocortical Evolution

open access: yes, 2013
Expansion of the neocortex is a hallmark of human evolution. However, it remains an open question what adaptive mechanisms facilitated its expansion.

Mitochondrial DNA lineages of Italian Giara and Sarcidano horses [PDF]

open access: yes, 2014
Giara and Sarcidano are 2 of the 15 extant native Italian horse breeds with limited dispersal capability that originated from a larger number of individuals. The 2 breeds live in two distinct isolated locations on the island of Sardinia. To determine the

Exercise‐specific plasma proteomic signatures in racehorses: Candidates for training adaptation and peak load monitoring

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Racehorses undergo profound physiological changes with training and competition, but current biomarkers inadequately capture the complex molecular dynamics of exercise. This study aimed to identify novel plasma biomarkers of training adaptation and peak load using high‐throughput proteomics.

Comparison of Enamel, Dentin, and the Dentin–Enamel Junction in Horse, Dog, Wild Boar, and Macaque Using Confocal Raman Microscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
Confocal Raman microscopy was used to map the dentin–enamel junction (DEJ) across four mammalian species. Chemical maps highlighted variations in mineral (phosphate/carbonate) and organic (amide/CH) phase. These results provide a comparative Raman framework to link tooth microchemistry with species‐specific structure and function.

Stereotypic horses (Equus caballus) are not cognitively impaired [PDF]

open access: yesAnimal Cognition, 2018
Stereotypies in animals are thought to arise from an interaction between genetic predisposition and sub-optimal housing conditions. In domestic horses, a well-studied stereotypy is crib-biting, an abnormal behaviour that appears to help individuals to cope with stressful situations.
