Allelopathic effects and root distribution of Ceratiola ericoides (Empetraceae) on seven rosemary scrub species.

Genetic insights into the biogeography of the southeastern North American endemic, Ceratiola ericoides (Empetraceae).

The southeastern United States harbors an unusually large number of endemic plant taxa, which may reflect the refugial nature of the region during Pleistocene glacial maxima. Understanding the genetic diversity and structure of extant plant taxa can provide insights into the biogeographical processes that shaped them genetically. Here, we investigate the levels and partitioning of allozyme dive...

Microhabitat distribution of two Florida scrub endemic plants in comparison to their habitat-generalist congeners.

Habitat-specialist species may be restricted to a narrower range of microhabitats than habitat-generalist species. We addressed this hypothesis by comparing microhabitats of two pairs of congeners that differ in habitat specificity and co-occur in one distinct habitat type, Florida rosemary scrub. We characterized microhabitats of rosemary scrub specialists, Polygonella basiramia and Lechea cer...

Spatial genetic structure of the southeastern North American endemic, Ceratiola ericoides (Empetraceae).

Understanding the spatial distribution of genetic diversity (i.e., spatial genetic structure [SGS]) within plant populations can elucidate mechanisms of seed dispersal and patterns of recruitment that may play an important role in shaping the demography and spatial distribution of individuals in subsequent generations. Here we investigate the SGS of allozyme diversity in 2 populations of the so...

Population Structure and Spatial Pattern in the Dioecious Shrub Ceratiola ericoides

Allelopathic effects of rhizome aqueous extract of Cynodon dactylon L. on seed germination and seedling growth of Legumes, Labiatae and Poaceae Homa Mahmoodzadeh* and Mitra Mahmoodzadeh

Allelopathic effects of aqueous extract of rhizomes of  Cynodon dactylon L. were studied on seed germination and seedling growth of three legume crops (Phaseolus vulgaris L., Pisum sativum L., and Vicia faba L.), three Labiatae species (Thymus vulgaris L., Melissa officinalis L., and Mentha spicata L.), and two species of Poaceae (Avena fatua L., Sorghum halepense L.). Seed germination of all L...
