People and Nature, EarlyView.Abstract Volunteers have been involved in nature observations for decades through citizen science initiatives, providing large data sets as well as problem identification that allow a more complete understanding of many natural phenomena. Although communication is a core component in citizen science, the key factors that determine its effectiveness in ...

The potential of seedbank digital information in plant conservation
PLANTS, PEOPLE, PLANET, EarlyView.Seedbanks are vital for biodiversity conservation, but their potential remains underutilised due to a limited understanding of the intraspecific genetic diversity they hold. By leveraging digitised data associated with seedbank collections, such as sampling locations, number of maternal plants and seed traits, we can attempt the estimation of genetic ...

Organic farming and gene transfer from genetically modified crops [PDF]
, 1999 This is the final report of MAFF/Defra project OF0157. Genetically modified (GM) crops cannot be released into the environment and used as food, feed, medicines or industrial processing before they have passed through a rigorous and internationally ...

Development and adoption of Kernza—A perennial grain crop for sustainable agriculture
PLANTS, PEOPLE, PLANET, EarlyView.Annual cereal grains account for ~50% of human food calories, but cultivation of these crops has resulted in major environmental and social issues worldwide. For nearly three decades, researchers have been breeding intermediate wheatgrass—a perennial cool‐season grass—to serve as the world's first commercial‐scale perennial grain crop to improve ...

Seed Mass and Morphology in Outcrossing and Selfing Species of Clarkia (Onagraceae): An SEM Study [PDF]
, 2004 Seeds from three pairs of outcrossing-selfing sister taxa from the genus Clarkia (farewell-to-spring, Onagraceae)—Clarkia unguiculata, Clarkia exilis, Clarkia xantiana ssp. xantiana and ssp. parviflora, and Clarkia concinna ssp.

Outcrossing rates as related to plant density in Phlox drummondii [PDF]
Heredity, 1990 Outcrossing rates were investigated in 20 populations of Phlox drummondii using polymorphic allozyme loci. The analysis of progeny genotype arrays gave outcrossing estimates which varied from f = 0·69 to 1·01; the mean was 0·86. The estimated outcrossing rate deviated significantly from random mating in 13 populations. The deviation was due principally

A century of theories of balancing selection
Biological Reviews, EarlyView.ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.
