Natural Areas and Reference Collections for Environmental Education in Some Arkansas Schools [PDF]

, 1973
A survey of 20 school campuses throughout Arkansas showed that most lack natural areas for outdoor environmental education. For most Arkansas schools no checklists of local plants are available, and there are no reference collections at the schools ...

BRL1 and BRL3 are novel brassinosteroid receptors that function in vascular differentiation in Arabidopsis [PDF]

, 2004
Plant steroid hormones, brassinosteroids (BRs), are perceived by the plasma membrane-localized leucine-rich-repeat-receptor kinase BRI1. Based on sequence similarity, we have identified three members of the BRI1 family, named BRL1, BRL2 and BRL3.

Dark diversity reveals importance of biotic resources and competition for plant diversity across habitats

Ecology and Evolution, 2020
Species richness is the most commonly used metric to quantify biodiversity. However, examining dark diversity, the group of missing species which can potentially inhabit a site, can provide a more thorough understanding of the processes influencing ...

The relationships of vascular plants [PDF]

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000
Recent phylogenetic research indicates that vascular plants evolved from bryophyte–like ancestors and that this involved extensive modifications to the life cycle. These conclusions are supported by a range of systematic data, including gene sequences, as well as evidence from comparative morphology and the fossil record.

High potential for weathering and climate effects of non-vascular vegetation in the Late Ordovician [PDF]

, 2016
It has been hypothesized that predecessors of today’s bryophytes significantly increased global chemical weathering in the Late Ordovician, thus reducing atmospheric CO2 concentration and contributing to climate cooling and an interval of glaciations ...

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.
