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

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2214-2239, October 2026.
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

Understanding Plant Parasitism: Hydnora Africana and European Scientific Practice in the Early Nineteenth Century**

open access: yesBerichte zur Wissenschaftsgeschichte, Volume 49, Issue 3, Page 315-334, September 2026.
This article will analyze the uncertainties around collecting and classifying Hydnora africana in the first half of the nineteenth century. Emerging from the distinctive dryland ecologies of South Africa, Hydnora was interpreted as strange and cryptic by Europeans primarily because it is a root parasite—a complex floral trait that was little understood.

Mitogenome characterization and phylogenetic relationships of Turkish horses (Equus caballus)

open access: yesTrakya University Journal of Natural Sciences
Background: Horses (Equus caballus) have been selectively bred for numerous purposes since their domestication, leading to various breeds and increased genetic diversity within the species. Aims: This study focused on the mitogenome characterization and

Fire regime shift reveals 17th century socio‐ecological change in the Rio Grande del Norte National Monument, New Mexico

open access: yesEcosphere, Volume 17, Issue 9, September 2026.
Abstract Humans have influenced ecosystems for millennia, and social changes can have notable ecological effects. Recent human influence on ecosystems is exemplified by the collapse of fire regimes circa 1900 in the western United States due to increased grazing, fire suppression, and declining Indigenous fire use.

Tiny but mighty: Insects can drive carrion decomposition in the absence of facultative vertebrate scavengers

open access: yesEcology, Volume 107, Issue 9, September 2026.
Abstract Scavengers play a key role in recycling animal biomass, yet the relative contributions of insects and vertebrates to this process remain poorly understood. Moreover, understanding whether one scavenger group can compensate for the absence of another is critical for predicting how carrion decomposition may respond to changes in community ...

Unveiling the Functional Role of KIF21B in Microglia Inflammatory Response

open access: yesGlia, Volume 74, Issue 9, September 2026.
Microglia express KIF21B in both sexes. KIF21B binds to microglia cytoskeleton; inflammation alters such interaction promoting a phagocytic state in females. In male microglia KIF21B modulates migration. ABSTRACT Microglia are brain immune cells that maintain homeostasis and respond to injury, changing cell morphology to drive inflammation, migration ...

Modulating Hunting Atmospheres: Mud and Material Flows Beyond the Kill

open access: yesAmerican Anthropologist, Volume 128, Issue 3, Page 629-639, September 2026.
ABSTRACT This article argues that hunting is not a bounded event but a materially redistributed atmosphere that extends beyond the kill and across field, truck, clothing, and home. Drawing on long‐term ethnographic fieldwork with wild boar hunters in Uruguay, I show how mud, odors, blood, and bodily residues carry the sensory, affective, and material ...

From Cohesion to Norms: How Animal Groups Come, Stay, and Function Together

open access: yesEthology, Volume 132, Issue 9, Page 604-622, September 2026.
The present review underscores two salient points: In the context of evolutionary transitions to pair‐ and group living, it is imperative to acknowledge the distinction between selective forces that act during the origin of these social systems and those that act during their subsequent maintenance.

Determining Home Range and Preferred Habitat of Feral Horses on the Nevada National Security Site Using Geographic Information Systems [PDF]

open access: yes, 2014
Feral horses (Equus caballus) are free-roaming descendants of domesticated horses and legally protected by the Wild and Free-Roaming Horses and Burros Act of 1971, which mandates how feral horses and burros should be managed and protected on federal ...
