Using herbarium collections to study genetic responses to global change

open access: yesNew Phytologist, EarlyView.
Summary Earth's c. 406 million herbarium specimens represent a largely untapped resource of genetic data that could transform our understanding of global plant populations. Advances in DNA sequencing have made the extraction of genetic data from these preserved specimens increasingly feasible, enabling new insights into plant biodiversity and ...

Invasive plants optimize leaf nitrogen allocation in photosynthesis

open access: yesNew Phytologist, EarlyView.
Summary Invasive plants often outcompete co‐occurring native species by expressing acquisitive functional traits that promote high photosynthetic capacity. However, it remains unclear whether these traits are newly evolved in the introduced (‘away’) range or if invaders arrived preadapted with superior traits from their native (‘home’) range.

Ambrosia (ragweed) pollen — A growing aeroallergen of concern in South Africa

open access: yesWorld Allergy Organization Journal
Background: Ragweed is an invasive, highly allergenic weed predicted to expand its habitat with warming global temperatures. Several Ambrosia species have been identified in South Africa for well over a century; however, its presence remained undetected ...

Revegetation seeding provides broad‐scale efficacy to inhibit the growth of Rhamnus cathartica seedlings across Minnesota, United States

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Removal of Common buckthorn (Rhanmus cathartica) can leave legacies that promote rapid reestablishment of managed populations. By sowing native plant seeds into management areas, managed communities can exert greater biotic resistance against reestablishing invasive plants.

Why is biocontrol of common ragweed (Ambrosia artemisiifolia), the most allergenic weed in Eastern Europe, still only a hope? [PDF]

open access: yes, 2007
This chapter presents the story of a long and as yet unsuccessful struggle to find suitable fungal and/or insect biocontrol agents for ragweed, a plant that became a widespread allergenic weed in Eastern Europe.
