Genomic insights into the origin of ecotypes

Trends in Ecology & Evolution
A century ago, Göte Turesson introduced the ecotype concept to describe populations of species that are phenotypically and genetically differentiated by adaptation to contrasting habitats. His simple idea—that ecological divergence can occur below the species level—has had lasting influence, inspiring experimental tests of local adaptation across taxa.

Integrated phytochemical and bioactivity profiling of Xanthium strumarium fruits from Korea and China: Implications for origin‐specific quality specification

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Geographic origin influences the phytochemical composition and biological activities of medicinal plant resources. Xanthium strumarium L. (XS) fruit is widely used in East Asian traditional medicine. However, current pharmacopeial standards primarily recognize Chinese‐derived material, despite the availability and traditional use of

Microdiversity of an Abundant Terrestrial Bacterium Encompasses Extensive Variation in Ecologically Relevant Traits

mBio, 2017
Much genetic diversity within a bacterial community is likely obscured by microdiversity within operational taxonomic units (OTUs) defined by 16S rRNA gene sequences. However, it is unclear how variation within this microdiversity influences ecologically

Historical data reveal earlier flowering under environmental change

Nordic Journal of Botany, EarlyView.
Global temperatures have risen ~ 1.1°C since the 1800s and the mean annual air temperature in the Arctic has increased by nearly four times the global average. Temperature has a significant effect on fundamental life‐cycle events of flora and fauna. With temperatures increasing, Arctic plants are expected to shift their active periods accordingly, with

Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

Capsicum chinense as an African traditional vegetable: Culture, resilience, and opportunity

PLANTS, PEOPLE, PLANET, EarlyView.
Capsicum chinense is central to everyday diets, cultural identity, and smallholder livelihoods across Sub‐Saharan Africa, yet remains overlooked in agricultural research and policy. This paper reframes C. chinense as a traditional, climate‐resilient vegetable shaped by centuries of farmer stewardship and cultural selection.

Genetic characterization of promising high-yielding cashew (Anacardium occidentale L.) cultivars from Côte d'Ivoire

Biotechnologie, Agronomie, Société et Environnement, 2020
Description of the subject. Cashew was introduced to Côte d'Ivoire in 1951 to control erosion and reforest cutover lands. From 1972 to 1980, natural forest plantations were converted to fruit orchards and were supplemented by the ‘Jumbo’ cashew variety ...

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

PLANTS, 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 ...

CSRcalculator: A reproducible framework for understanding plant ecological strategies

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants respond to environmental change is essential for conserving biodiversity and managing ecosystems under climate change. We developed CSRcalculator, an open‐source platform that brings together major competitor, stress‐tolerator, ruderal (CSR) models to make ecological strategy classification accessible, reproducible and scalable.
