A study was conducted during Zaid 2005, in Uttar Pradesh, India, to evaluate the nature and magnitude of genetic divergence in 30 bitter gourd genotypes. Results revealed the presence of wide genetic diversity. The genotypes were grouped into 6 clusters based on Mahalanobis D statistics using Tocher's 2 method. The clustering pattern of genotypes revealed that the genetic diversity was independ...

Marine angiosperms, or seagrasses, continue to be a major focus of marine biologists because of their important ecological role in many coastal ecosystems. Seagrass population biology could benefit from a population genetic perspective because genetic data enable the extraction of useful demographic information such as isolation and gene flow between demes. Moreover, population genetic processe...

So, what’s the verdict, good or bad? Boring algae clearly have important functions in reef ecosystems and will influence how they cope with climate change and ocean acidification in the near future. However, we cannot yet give a verdict as to whether they will act as a buffer against these environmental changes or make the situation worse. Little is known about the ecophysiological diversity of...
