"Two tribes": Handaxe shape variation shows distinct regional cultural groups in southeastern Britain between 424 000 and 374 000 BP

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological ...

Astragalus ecomorphology in Quaternary elephantids

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The astragalus plays a fundamental role in the graviportal locomotion of proboscideans, reflecting the biomechanical constraints imposed by large body masses. This study analyses the morphological variability of the astragalus in Quaternary elephantids using linear biometry and 3D geometric morphometrics, incorporating an unpublished ...

Nutritional characterization of Cusco green tea and its synergistic effect with omega‐3 on metabolic and cognitive dysfunctions in obese rats

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Obesity and its metabolic complications, such as insulin resistance and cognitive decline, remain a global health challenge. Green tea (Camelia sinensis) and ω‐3 polyunsaturated fatty acids (PUFAs) are recognized for their antioxidant, anti‐inflammatory, and neuroprotective properties.

Comprehensive Evidence for Mortality and Underlying Morbidity Related to Visceral Fat Distribution

open access: yesMed Research, EarlyView.
ABSTRACT Linking obesity to mortality is an intriguing and controversial topic. This study tried to comprehensively assess 8 adiposity surrogates and mortality association among middle‐to‐old‐aged adults to identify a superior one, and explore explanatory disorders. Data sources included the National Health and Nutrition Examination Survey (NHANES), UK

Temporal changes in the dietary niche of sympatric seals provides insight into the role of competition in population declines

open access: yesOikos, EarlyView.
Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina

Fruit use and fruit processing by euphonias, specialized avian frugivores

open access: yesOikos, EarlyView.
Euphonias (Neotropical passerines in the genera Euphonia and Chlorophonia) form the quintessential example of a specialized avian frugivore, combining a high reliance on fruit as food and the restriction of fruit taxa exploited. To understand their specialization, we explored the integration of fruit morphological and nutritional traits with their ...
