Weed presence altered biotic stress and light signaling in maize even when weeds were removed early in the critical weed‐free period

open access: yesPlant Direct, 2018
Weed presence early in the life cycle of maize (typically, from emergence through the 8 to 12 leaf growth stage) can reduce crop growth and yield and is known as the critical weed‐free period (CWFP).

Selection for persistence of endophyte‐free meadow fescue under intensive grazing versus frequent mowing

open access: yesGrassland Research, EarlyView.
Cattle grazing meadow fescue pasture in remnant oak savanna near Fennimore, Wisconsin. Abstract Background Meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.) is highly adapted to managed rotational grazing systems with sufficient rest periods to promote regrowth and sward longevity.

Diterpenoid Diversity across Land Plants

open access: yesHelvetica Chimica Acta, EarlyView.
Here we bridge the knowledge of diterpene chemical diversity, biosynthesis, and evolution from nonvascular mosses and liverworts to that known from vascular plants. ABSTRACT The diverse array of diterpenoid natural products stems from the ease of manipulating the promiscuity of diterpene cyclases.

Diversity and Life History Traits of Native Weed Communities in Agricultural Areas: A Case Study in Eastern China

open access: yesBiology
Native weeds have a long history of adaptation to local environments. Understanding the relationship between the occurrence of native weeds and their life history traits is crucial for effective weed management and risk assessment of plant invasions.

Managing water resources and aquatic invaders: Public preferences, stakeholder perspectives, and policy implications

open access: yesJournal of the Agricultural and Applied Economics Association, EarlyView.
Abstract Aquatic invasive species threaten water resources by reducing biodiversity, disrupting ecosystems, and impeding recreation. Managing these invaders is challenging due to public concerns over chemical control methods and conflicting stakeholder preferences.

Turning Down Mum's Cooking: The Ethics of Dietary Difference within Families

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Although food ethicists have called for greater attention to the relational context of eating for over a decade, the context of ‘eating with family’ remains largely ignored. But the family is both a morally specific relational context and one within which many people do most of their eating.

Perennial Legumes Pueraria phaseoloides and Leucaena leucocephala Exhibit High Potential for Fertility Restoration of Degraded Mined Soils in Ghana

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
Revegetating the subsoil layer of abandoned gold mined sites with the perennial legumes Leucaena Leucocephala, Pueraria phaseoloides and Gliricidia sepium without any soil amendments increases the content of soil organic carbon and important macro‐nutrients, which are crucial for restoring soil health and productivity. These improvements in soil health

From shape to source: sedimentary charcoal morphology as a proxy for tropical burned biomass composition

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary charcoal elongation is increasingly being used in paleoecology to distinguish herbaceous from woody fuel in past fires. However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and
