A Bayesian framework to estimate diversification rates and their variation through time and space [PDF]

open access: yes, 2011
Background: Patterns of species diversity are the result of speciation and extinction processes, and molecular phylogenetic data can provide valuable information to derive their variability through time and across clades.

The influence of a cluster‐rooted species on Bossiaea linophylla (Fabaceae) under extremely phosphorus‐impoverished conditions: Phosphorus competition and altered plant–microbe interactions

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Phosphorus (P) limitation may intensify plant competition. However, in severely P‐impoverished soils of south‐western Australia, cluster‐rooted Banksia attenuata (Proteaceae) can facilitate P acquisition of neighbouring species by mobilising tightly bound P from soil ...

Temporary nutrient deficiency - a difficult case for diagnosis and prognosis by plant analysis [PDF]

open access: yes, 2000
Plant analysis aims to either detect deficiency at the time of sampling (diagnosis) or predict its occurrence at a later stage of growth (prognosis). Its use is based on the presumption that the plant nutrient status will either be constant with plant ...

Art v 1 and Amb a 4 Co‐Sensitization Identifies Italian Patients at Risk for Mugwort‐Celery‐Spice Syndrome

open access: yesAllergy, EarlyView.
Three molecular profiles identified among Art v 1/Amb a 4‐sensitized patients: Art v 1 monosensitization, Amb a 4 monosensitization, and dual sensitization to both allergens. Art v 1 monosensitization was predominantly associated with allergic rhinitis, reflecting a classical airborne allergy pattern.

Variable species establishment in response to microhabitat indicates different likelihoods of climate‐driven range shifts

open access: yesEcography, EarlyView.
Climate change is causing geographic range shifts globally, and understanding the factors that influence species' range expansions is crucial for predicting future biodiversity changes. A common, yet untested, assumption in forecasting approaches is that species will shift beyond current range edges into new habitats as they become macroclimatically ...

A study of brown spot disease of Lupinus spp. caused by Pleiochaeta setosa (Kirchner) Hughes : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Massey University of Manawatu [PDF]

open access: yes, 1964
Photo missing from only copy pg 194Lupins (Lupinus) are leguminous plants grown in most countries, from the hot equatorial lands of Egypt, North Africa, and Brazil, to the cooler climates of New Zealand and Chile.

Lagged climate‐driven range shifts at species' leading, but not trailing, range edges revealed by multispecies seed addition experiment

open access: yesEcography, EarlyView.
Climate change is causing many species' ranges to shift upslope to higher elevations as species track their climatic requirements. However, many species have not shifted in pace with recent warming (i.e. ‘range stasis'), possibly due to demographic lags or microclimatic buffering.

A Vertical Stacking Approach to Rapid Generation Cycling for Indoor Growth of Tall Annual Crops—The Case of Vicia faba L.

open access: yesPlant Breeding, EarlyView.
ABSTRACT Accelerating breeding cycles through rapid generation turnover is a demonstrated strategy to improve the rate of genetic gain in a range of staple crops. This study presents a vertically stacked accelerated single‐seed descent (aSSD) protocol for faba bean (Vicia faba L.), aimed at rapid generation cycling while ensuring robust plant ...

Hypoglycemic effect of Lupinus mutabilis in healthy volunteers and subjects with dysglycemia Efecto hipoglicemiante de Lupinus mutabilis en voluntarios sanos y sujetos con disglicemia

open access: yesNutrición Hospitalaria, 2012
Metabolic syndrome and type-2 diabetes are increasing health problems that negatively affect health care systems worldwide. There is a constant urge to develop new therapies with better effects, lower side effects at lower prices to treat these diseases.

Comparing conventional and improved organic vegetable rotations, yields and nitrogen husbandry [PDF]

open access: yes, 2010
During 2005 to 2009 three approaches to organic vegetable rotations were compared to a conventional rotation in an interdisciplinary project. The organic rotations differed in their reliance on animal manure vs.
