Zoo Biology, EarlyView.Female white rhinos in zoos systematically exceed the body mass range for free‐ranging specimens; this is not the case in black rhinos. ABSTRACT The body mass of zoo animals may differ from those in wild populations due to the different environmental and dietary conditions being offered under human‐managed care.

Scaling the propulsive performance of heaving and pitching foils
, 2017 Scaling laws for the propulsive performance of rigid foils undergoing oscillatory heaving and pitching motions are presented. Water tunnel experiments on a nominally two-dimensional flow validate the scaling laws, with the scaled data for thrust, power ...

Journal of the Royal Anthropological Institute, EarlyView.Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Integrative Zoology, EarlyView.The audiogram of the world's first successfully captive‐born Yangtze finless porpoise was on average 40 dB higher than conspecifics. Congenital hearing disorders and noise exposure may be the primary cause of porpoise's hearing loss. ABSTRACT Aquariums globally have seen significant growth in recent decades.

Can culture be solely inferred from the absence of genetic or environmental factors ? [PDF]
, 2001 Rendell & Whitehead's minimalist definition of culture does not allow for the important gaps between cetaceans and Inimans. A more complete analysis reveals important discontinuities that may be more instnictive for comparative purposes than the ...

Integrative Zoology, EarlyView.This work aimed to apply the principles of skin mark analysis to a cetacean species to build a sex‐discrimination model exclusively based on photographic material. Relevant differences between sexes emerged in markings, with males presenting more social, aggression‐related, and fishing‐related marks overall, and a stronger tendency of mark accumulation
