Tracheal chambers as a key innovation for high‐frequency emission in bat echolocation

The Anatomical Record, EarlyView.
Abstract Key innovations are pivotal for biodiversity and facilitating evolutionary success, enabling organisms' adaptation to various ecological niches through the diversification of phenotypic traits. In mammals, notable adaptations include evolving hypsodonty for grazing on grasses and, for bats, evolving echolocation and wing acquisition.

The pelvis doesn't walk by itself: Wider pelves reduce the cost of walking over unstable surfaces

The Anatomical Record, EarlyView.
Abstract Walking over variable and/or unstable terrain is a key aspect of daily life and was crucial to the evolution of bipedalism. The ability to find gait solutions that maintained stability over uneven terrain for the least increase in metabolic cost was likely a hallmark of locomotor effectiveness in early humans, in particular acting as an ...

Leaving children behind for cross‐border education: Unveiling the emotional agency of international post‐graduate student mothers

British Educational Research Journal, EarlyView.
Abstract Despite growing interest in the internationalisation of higher education, the experiences of international student parents, particularly international student mothers, remain largely marginalised in research and policy. This paper examines the emotional agency of international student mothers who leave their children behind in their home ...

Comparative Analysis of Bioreactor Design and Scale‐Up for Cultivated Meat Using Monte Carlo‐Based Timescale Modeling

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Cultivated meat offers a sustainable alternative to conventional livestock production but faces significant scale‐up challenges, particularly in bioreactor design for mammalian cell suspension cultures. This study presents a comparative analysis of stirred tank reactors (STR), bubble columns (BC), and airlift reactors (ALR) to assess their ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.
