Marine microbial diversity
Microbes were the only form of life for the first 2-3 billion years of planetary and biological evolution. Life most likely began in the oceans and marine microorganisms are the closest living descendants of the original forms of life. Early marine microorganisms also helped create the conditions under which subsequent life developed. More than two billion years ago, the generation of oxygen by...
متن کاملMicrobial diversity of marine sponges.
The recent application of molecular microbial ecology tools to sponge-microbe associations has revealed a glimpse into the biodiversity of these microbial communities, that is considered just 'the tip of the iceberg'. This chapter provides an overview over these new findings with regard to identity, diversity and distribution patterns of sponge-associated microbial consortia. The sponges Aplysi...
متن کاملMarine microbial diversity: can it be determined?
Estimates of the order of magnitude for the total number of microbial species on Earth range from 10(3) to 10(9). Despite global dispersal of microorganisms, this number is probably rather large. The total biodiversity of an ecosystem is composed of two elements: first, a set of abundant taxa that carry out most ecosystem functions, grow actively and suffer intense losses through predation and ...

متن کاملMarine microbial diversity and ecology: importance and future perspectives
The world ocean with a coastline of 312,000 km (193,000 miles) and a volume of 137 × 10 km, is the largest ecosystem on earth, and has been used for a variety of purposes by man for millennia. Because of its large volume and vast area, influence of the world ocean on world climate is profound. Microorganisms occur nearly everywhere in nature and occupy an important place in human view of life. ...
