Biological 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,

Ground‐truthing of satellite imagery to assess seabird colony size: A test using Adélie penguins
Remote Sensing in Ecology and Conservation, EarlyView.Adélie penguin colony size can be estimated from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery due to the contrast between their guano stain and the surrounding terrain. Our study assessed the utility of VHR imagery for making indirect assessments of changes in colony size.

Using blubber explants to investigate adipose function in grey seals:glycolytic, lipolytic and gene expression responses to glucose and hydrocortisone [PDF]
, 2017 Adipose tissue is fundamental to energy balance, which underpins fitness and survival. Knowledge of adipose regulation in animals that undergo rapid fat deposition and mobilisation aids understanding of their energetic responses to rapid environmental ...

Methods in Ecology and Evolution, EarlyView.Abstract Estimating demographic rates of wild populations is critical to understanding their dynamics but can be challenging because large amounts of data are required, and parts of the life cycle of individuals may be unobserved. In numerous research programmes, capture–recapture (CR) data and biologging data are collected in parallel.

Work minimization accounts for footfall phasing in slow quadrupedal gaits [PDF]
, 2017 Quadrupeds, like most bipeds, tend to walk with an even left/right footfall timing. However, the phasing between hind and forelimbs shows considerable variation.

Exploring dietary adaptations in Ursus minimus: a 3D geometric morphometric analysis of the mandible
Boreas, EarlyView.Using 3D geometric morphometrics, the dietary adaptations of the extinct Auvergne bear (Ursus minimus) are analysed. Its mandibular morphology aligns more closely with omnivorous rather than insectivorous bears, challenging current ideas. The extinct bear Ursus minimus, which lived in Europe during the Pliocene and possibly Early Pleistocene, is ...

PLoS ONE, 2013 Dramatic environmental changes associated with global cooling since the late Miocene, and the onset of glacial-interglacial cycles in the Pleistocene served as a backdrop to the evolutionary radiation of modern bears (family Ursidae). These environmental

An Adaptive Threshold in Mammalian Neocortical Evolution
, 2013 Expansion of the neocortex is a hallmark of human evolution. However, it remains an open question what adaptive mechanisms facilitated its expansion.

Boreas, EarlyView.Bears deviate from the inhibitory cascade model (ICM) during molar size evolution, with two significant deviations linked to changes in diet: Ursus minimus and Ursus deningeri. Many bears exhibit a ‘partial ICM’, highlighting the relationship between relative molar size, dietary adaptations and dental development across different species.
