The production of two or more seed types by a single plant is known as seed heteromorphism. There have been many comparisons of seed traits or growth between plants grown from heteromorphic seeds. However, information is scarce regarding the mineral contents of adult plants from heteromorphic seeds. We herein present biomass and mineral profiles of adult plants grown from dimorphic seeds (non-d...

Superhydrophobic surfaces of plants and animals are of great interest for biomimetic applications. Whereas the self-cleaning properties of superhydrophobic surfaces have been extensively investigated, their ability to retain an air film while submerged under water has not, in the past, received much attention. Nevertheless, air retaining surfaces are of great economic and ecological interest be...

A feedback between decomposition and litter chemical composition occurs with decomposition altering composition that in turn influences the decomposition rate. Elucidating the temporal pattern of chemical composition is vital to understand this feedback, but the effects of plant species and climate on chemical changes remain poorly understood, especially over multiple years. In a 10-year decomp...

Three Merino sheep were given 3 g/kg of dried, finely-milled Homeria glauca (Natal yellow tulp) plant material intraruminally. Plasma glucose, cortisol, catecholamines and lactate were measured hourly and also at the moment of death. Rising plasma glucose was shown to be associated with rising plasma cortisol and catecholamines, and the metabolic component of tulp-associated acidosis was shown ...

Bemisia tabaci is a key virus vector on several crops worldwide. Then, a preventive approach to deal with viral epidemics may be the deployment of repellents or phagodeterrents at earlier stages of plant development (critical period). Thus, the crude extract and four fractions thereof (water, water: methanol, methanol, and diethyl ether) of bitterwood (Quassia amara, Simaroubaceae) were tested ...
