Humans are not unique: difficult birth is common in placental mammals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological 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.

Sex Prediction From the Clavicle Using Computerized Tomography Images via Traditional and Hybrid Deep Learning Models

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The aim of this study is to perform high accuracy sex prediction from clavicle images using proposed hybrid deep learning models and traditional deep learning models. The clavicle of 807 female and 805 male individuals obtained from Computed Tomography were segmented in 3D format and saved in jpeg format as superior–inferior and right–left ...

Weaving strength and care: Situated reflections on women's work and the epistemology of care in biological anthropology

open access: yesFeminist Anthropology, EarlyView.
Abstract This essay examines how gendered expectations, structural precarity, and institutional hierarchies shape research practices, knowledge production, and career trajectories in biological anthropology. Taking the figure of the “strong woman” as an entry point, it questions celebratory narratives of resilience that frame endurance as an individual

Materials and Music: Selective Imperfection as a Generative Framework for Analysis, Creativity and Discovery

open access: yesInterdisciplinary Materials, EarlyView.
Vibrations in matter, from spider webs to molecules, water to flames, share a grammar with music. We propose that creativity emerges when constraints force expansion beyond existing possibilities. Selective imperfection restores balance, enabling invention.

A Coarse Geometric Approach to Graph Layout Problems

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT We define a range of new coarse geometric invariants based on various graph–theoretic measures of complexity for finite graphs, including treewidth, pathwidth, cutwidth and bandwidth. We prove that, for bounded degree graphs, these invariants can be used to define functions which satisfy a strong monotonicity property, namely, they are ...

The Impacts of Southwest Indian Ocean Tropical Cyclones on Transient Weather in Réunion

open access: yesInternational Journal of Climatology, EarlyView.
Tropical cyclones which make passage near Réunion can have significant impacts on transient weather relative to long‐term means on the island. In this paper, these impacts were determined by a topological analysis of non‐landfalling tropical cyclones. The relationship between storm intensity, distance, duration, and seasonality plays an equal role in ...

From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar Stone

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Altar Stone, the 6000 kg central sandstone megalith at Stonehenge in southern England, is suggested to have originated from the Orcadian Basin in northeast Scotland, some 700 km away. However, its source location within this large basin remains unresolved and its mode of transport uncertain.

Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

Can DNA from wet, temperate soils be used for palaeoecological reconstruction?

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary ancient DNA in well‐dated contexts (sedaDNA) has great potential as a palaeoecological proxy. A few studies have attempted palaeoecological reconstructions using sedaDNA from soil; these studies have been mainly restricted to cold and/or dry soils.
