From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy
The Anatomical Record, EarlyView.Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

Science Advances, 2015 The world’s largest predators, blue whales, switch strategies to maximize foraging efficiency as a function of prey density and depth. Terrestrial predators can modulate the energy used for prey capture to maximize efficiency, but diving animals face the

The Anatomical Record, EarlyView.Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Influences on the use of gravel roads as night roosts by Common Nighthawks in the boreal forest
Avian Conservation and EcologyCommon Nighthawks ( Chordeiles minor ), like other nightjars, often sit on gravel roads at night where they are at risk of being struck by passing traffic, but neither the reasons behind their use of roads nor the frequency of traffic strikes are fully ...

Foraging across the life span: Is there a reduction in exploration with aging?
Frontiers in Neuroscience, 2013 Does foraging change across the life span, and in particular, with aging? We report data from two foraging tasks used to investigate age differences in search in external environments as well as internal search in memory.

The Anatomical Record, EarlyView.Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of
