Spatial distribution and reproductive phenology of sexual and asexual Mastocarpus papillatus (Rhodophyta).

New, resurrected and redefined species of Mastocarpus (Phyllophoraceae, Rhodophyta) from the northeast Pacific

Recent molecular phylogenetic investigations of the red algal genus Mastocarpus from the northeast Pacific resolved numerous cryptic species. Although species were clearly defined through genetic analyses, the correct names to apply to the species remained unclear due to both morphological variability within species and morphological similarity between species. To determine the appropriate name...

Novel distribution pattern between coexisting sexual and obligate asexual variants of the true estuarine macroalga Ulva prolifera †

Where sexual and asexual forms coexist within a species, the asexuals are often found to be prevalent in marginal habitats. This asexual distribution pattern has received evolutionary attention linked to the paradox of sex. In many marine species, there is a distributional trend of asexual modes being more common in lower salinity waters regarded as the ecogeographic marginal, being explained b...

تغییرات مکانی تجدید حیات و تنوع گونه‌های درختی در جنگل‌‌های زاگرس، مطالعه موردی: جنگل‌‌های گهواره در استان کرمانشاه

The regeneration is one of the most important phenomena in forest ecosystems and the most important factor of development and sustainability of forests. Assessment of the regeneration is one of the best criteria for monitoring forest function stability. The aim of this study was to investigate the spatial variability of regeneration diversity and its relationship with tree species diversity in ...

Investigation on sexual and asexual propagation methods of damask rose (rosa damascena mill.)

The efficiency of the red alga Mastocarpus stellatus for remediation of cadmium pollution.

This work reports the results of the study for cadmium binding by the dead red macroalga Mastocarpus stellatus. Kinetics sorption experiments demonstrated the high rate of metal biosorption: the system attained over 50% of the total biomass cadmium uptake within 2 min of contact and over 90% in the first 9 min. The kinetic data were successfully described by a pseudo-second order model with rat...
