Body Size, Dental Pathology, and Maternal Genetic Diversity of Ancient Horses in the Eastern Baltic Sea Region and Western Russia

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The early evolutionary history of modern domestic horses (Equus caballus/Equus ferus caballus), known as the DOM2 lineage, is well documented due to numerous archaeological and ancient DNA (aDNA) studies. Although many uncertainties remain in the domestication timeline, current evidence suggests that the domestication of modern horses began in

Technical wildness: Modernity, romanticism, and the technocratic turn in Scottish rewilding

open access: yesPeople and Nature, EarlyView.
Abstract Technical wildness is a new and increasingly influential culture of nature. This paper marks its emergence in Scotland in the early 2020s. Focusing on Scotland's rapidly evolving land management sector, the paper traces how private rewilding companies position science‐led land management and natural capital markets as the most effective ...

Impact of plant breeding on the responsiveness of maize and wheat varieties to an arbuscular mycorrhizal fungal symbiont

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Field inoculation with arbuscular mycorrhizal fungi (AMF) offers a promising route to improve sustainable agriculture and food production, yet results are often variable. We investigated the mycorrhizal growth response of maize and wheat varieties recommended for farmers and found substantial variation under greenhouse conditions.

Leprosy in a Lombard-Avar cemetery in central Italy (Campochiaro, Molise, 6th–8th century AD): ancient DNA evidence and demography

open access: yesAnnals of Human Biology, 2017
Background: The study of past infectious diseases increases knowledge of the presence, impact and spread of pathogens within ancient populations. Aim: Polymerase chain reaction (PCR) was used to examine bones for the presence of Mycobacterium leprae ...

Ethnobotanical and genetic assessments of Central American avocado landraces reveal novel sources of biodiversity and ancient migration patterns

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Avocados are a multibillion‐dollar global commodity, but their growing export market pressures local farmers to abandon local fruit tree diversity in favor of commercial cultivar production. Interviews with rural avocado farmers and households from the Southern Mexican Highlands, Pacific Coastal Honduras, and Western Nicaragua, as well as the genetic ...

Herbaria as repositories of past soil properties and historical soil DNA

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Soil health is fundamental to agriculture, food security, and the sustainable management of terrestrial ecosystems under ongoing climate and land‐use changes. Soil microorganisms play a key role in these processes, yet how soils and their microbial communities have changed over time in response to global environmental change remains poorly understood ...

Chemical diversity and phylogenetic insights into Hawaiian ʻākia (Wikstroemia) species used in traditional fishing practices

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Traditional fishing with plant‐based piscicides is a global practice in decline, facing increasing restrictions. We investigated the chemical diversity of endemic Wikstroemia species historically used to stun or poison fish in Hawaiʻi. Using 1‐H‐NMR, principal component analysis, targeted HPLC, and target‐capture sequencing, we characterized compounds ...
