Andromonoecy is hypothesized to evolve as a mechanism enabling plants to independently allocate resources to female and male function. If staminate flower production is a mechanism to regulate allocation to female function (i.e., fruit production), then large-fruited species should be more strongly andromonoecious than smaller-fruited taxa because more resources are required to mature large fru...
BACKGROUND Sulfated polysaccharides from red marine algae have presented a variety of potentially therapeutic biological effects, however, their antinocicpetive and anti-inflammatory properties are not well understood. METHODS Male Swiss mice were pretreated with a sulfated polysaccharidic fraction obtained from the marine alga Acanthophora muscoides (AmII) (1, 3 or 9 mg/kg, iv) 30 min prior ...
Background and objectives: The antifungal activity of the essential oils and their constituents against some phytopathogenic fungi has been reported. Thymus vulgaris (Lamiaceae) is one of the Thymus species. A large number of studies have concerned the chemical compositions and antifungal activity of thyme’s oil. In order to reduce the use of synthetic fungic...
A detailed understanding of the genetic structure of populations and an accurate interpretation of processes driving contemporary patterns of gene flow are fundamental to successful spatial conservation management. The field of seascape genetics seeks to incorporate environmental variables and processes into analyses of population genetic data to improve our understanding of forces driving gene...
BACKGROUND Rochefortia is a small taxon of woody plants in the Ehretiaceae (Boraginales) exhibiting coriaceous leaves with cystoliths, small whitish flowers and drupaceous fruits containing four pyrenes. It shares the dioecious sex distribution with its sister group Lepidocordia and can be delimited from the latter (and all other Ehretiaceae) by the presence of thorns. Neotropical Rochefortia i...
