The scientific discipline of active restoration of denuded coral reef areas has drawn much attention in the past decade as it became evident that this ecosystem does not often recover naturally from… (More)

Theories of evolution that state natural selection acts on individuals have been modified to include multiple levels of selection. Here we demonstrate in chimeric protochordates that primitive germ… (More)
Germ cell sequestering in Animalia is enlightened by either, launching true germ line along epigenetic or preformistic modes of development, or by somatic embryogenesis, where no true germ line is… (More)
The study is aimed at introducing the hepatic level of metallothionein transcript in the fish Lithognathus mormyrus as environmental biomarker, including: (a). establishing real time PCR procedure… (More)
Many coral reefs worldwide are rapidly declining, but efficient restoration techniques are not yet available. Here, we evaluate methodologies for reef restoration based on the ‘‘gardening concept’’.… (More)
The current best management tools employed in coral reefs worldwide do not achieve conservation objectives as coral reefs continue to degrade. Even improved reef management helps, at best, to reduce… (More)
Stem cell populations exist in "niches" that hold them and regulate their fate decisions. Identification and characterization of these niches is essential for understanding stem cell maintenance and… (More)
Botryllus schlosseri, presumably a Mediterranean tunicate that became a worldwide distributed species, has colonized New Zealand islands during the last 2 centuries. Genetic diversity of 6… (More)
Fusion between conspecifics (chimerism) is a well-documented phenomenon in a variety of taxa. Chimerism and the subsequent mixing of genetically different stem cell lines may lead to competition… (More)
The reproduction of Stylophora pistillata, one of the most abundant coral species in the Gulf of Eilat, Red Sea, was studied over more than two years. Gonads were regularly examined using… (More)
