More than 230,000 known species representing 31 metazoan phyla populate the world's
oceans. Perhaps another 1,000,000 or more species remain to be discovered. There is …

DNA barcodes, like traditional sources of taxonomic information, are potentially powerful
heuristics in the identification of described species but require mindful analytical …

Describing biological diversity is a challenging endeavour, especially for the small, cryptic
animals that make up the meiofauna. The field of DNA taxonomy, ie, the use of DNA to …

Research using cytochrome c oxidase barcoding techniques on zoological specimens was
initiated by Hebert et al.[Hebert, PDN, Ratnasingham, S., deWaard, JR, 2003. Barcoding …

'Biodiversity'means the variety of life and it can be studied at different levels (genetic,
species, ecosystem) and scales (spatial and temporal). Last decades showed that marine …

DNA barcoding aims to accelerate species identification and discovery, but performance
tests have shown marked differences in identification success. As a consequence, there …

A decade has yielded much progress in understanding polar disturbance and community
recovery—mainly through quantifying ice scour rates, other disturbance levels, larval …

The Antarctic biota is highly endemic, and the diversity and abundance of taxonomic groups
differ from elsewhere in the world. Such characteristics have resulted from evolution in …

Acacia species are quite difficult to differentiate using morphological characters. Routine
identification of Acacia samples is important in order to distinguish invasive species from …

By depicting who eats whom, food webs offer descriptions of how groupings in nature
(typically species or populations) are linked to each other. For asking questions on how food …
