Evolutionary history and taxonomy of the genus Zea

American Journal of Botany, EarlyView.
Abstract Premise Taxonomic differentiation of teosinte species (Zea spp.), the closest relatives of maize (Z. mays) is crucial for understanding their distribution, ecology, and evolutionary history. Resolving the taxonomic uncertainties is of scientific interest and has practical implications for biodiversity management, preservation, and utilization.

Heterosis in crosses between remnant populations of the rare prairie forb Silene regia: Implications for restoration genetics

American Journal of Botany, EarlyView.
Abstract Premise Calls to adopt seed‐sourcing strategies in biological restoration that preserve local adaptation while maximizing genetic variation (e.g., regional admixture provenancing) are increasingly common. Heterosis, the increased fitness of progeny from crosses between populations relative to progeny from crosses within populations, could ...

A well‐resolved phylogeny of Cuscuta subgenus Monogynella based on data drawn from all three plant genomes

American Journal of Botany, EarlyView.
Abstract Premise Cuscuta (dodders) consists of ~200 species circumscribed into four subgenera (Monogynella, Cuscuta, Pachystigma, and Grammica) and is the only parasitic genus in Convolvulaceae (the morning‐glory family). This group shows a significant diversity in plastid functionality and represents a rare mixotrophic system among parasitic plants ...

Does withdrawing treatment from a pregnant persistent vegetative state patient resulting in her death constitute a termination of pregnancy

South African Journal of Bioethics and Law, 2015
A recent article on the Texas case of Munoz v John Peter Smith Hospital, begs the question whether if the pregnant woman had been in a persistent vegetative state (PVS) the courts in South Africa would have ordered the withdrawal of life-support ...

Persistent Vegetative State and the Right to Die: The United States and Britain

, 1991
...In Britain there has been little public discussion of the issue of withdrawing treatment from patients in a persistent vegetative state. Few would like to see the courts interfering in what most regard as clinical decisions, a view shared by most ...

Turning a new leaf: PhenoVision provides leaf phenology data at the global scale

Applications in Plant Sciences, EarlyView.
Abstract Premise Plant phenology dictates many aspects of community function and ecosystem dynamics. Yet, global phenology data are still limited, especially in areas lacking monitoring programs. Here we present a new data resource, PhenoVision–Leaf, which extends a computer vision pipeline utilizing iNaturalist digital image vouchers to produce global‐

Herbarium‐based measurements are reliable predictors of fresh plant traits in Neotropical Myrtaceae

Applications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens are increasingly used to extract morphological traits for ecological and evolutionary studies, yet the effects of tissue desiccation on trait measurements remain poorly understood. Here, we tested two hypotheses: (H1) whether higher tissue water content leads to greater measurement changes after herborization and ...

Petal to the metal: The slow road to automating large‐scale phenology labeling for herbarium specimens

Applications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens represent critical historical records of plant phenology, yet automating annotation of reproductive structures remains challenging given the diversity of floral morphologies, specimen age and quality, and image quality.
