Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

The potential effect of megafaunal extinctions on modern conservation of horse chestnut Aesculus hippocastanum

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...

Genetic evidence that Chinese chestnut cultivars in Japan are derived from two divergent genetic structures that originated in China.

open access: yesPLoS ONE, 2020
The Chinese chestnut (Castanea mollissima Bl.) was introduced into Japan about 100 years ago. Since then, a number of Chinese chestnut cultivars and Japanese-Chinese hybrid cultivars have been selected by farmers and plant breeders, but little ...

Using art history to explore society's changing connections with agriculture

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Food insecurity is a looming challenge that especially affects those least fortunate. Consumer food choices have a substantial impact on the sustainability of current food systems. Here, we use art as a lens through which to consider our contemporary and historical relationship to one of the world's most crucial crops, the potato, in the context of the

Tree Diversity Limits the Impact of an Invasive Forest Pest.

open access: yesPLoS ONE, 2015
The impact of invasive herbivore species may be lower in more diverse plant communities due to mechanisms of associational resistance. According to the "resource concentration hypothesis" the amount and accessibility of host plants is reduced in diverse ...

Accidental plant poisonings in France: Lessons from a decade of national toxicovigilance

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Accidental plant poisonings reveal how modern societies are losing everyday botanical knowledge once central to food and health safety. By analyzing a decade of French toxicovigilance data, this study shows that most severe cases arise from plant misidentification or misguided self‐medication.

Progress of collection, conservation and innovative utilization of chestnut resources in the National Walnut and Chestnut Germplasm Repository (Tai'an) [PDF]

open access: yesGuoshu xuebao
Chestnut, a deciduous tree of the genus Castanea in the Fagaceae family, is native to China and has a cultivation history of at least 2500 years. It is an important woody food crop and a long-lived economic fruit tree that can be planted once and ...

A Comparison of Mobile Laser Scanning Data Acquisition Methods in Closed Forest, Open Woodland and Sub‐Alpine Woodland Ecosystems

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that the mobile laser scanning (MLS) sampling density required to reliably characterise vegetation structure increases with a site's structural complexity. Applying a five‐level acquisition framework across open woodland, closed forest and sub‐alpine woodland ecosystems, we found that longer scanning paths increased the ...

Hands‐on and Minds‐on? Findings on the Instructional Support of Preschool Teachers to Foster Children's Understanding of Scientific Practices

open access: yesScience Education, EarlyView.
ABSTRACT To participate effectively in modern society, it is essential to have both knowledge of scientific concepts and an understanding of scientific practices. Children develop initial knowledge and skills to engage in scientific practices, such as identifying patterns, long before entering school.
