Foliose Ulva Species Show Considerable Inter‐Specific Genetic Diversity, Low Intra‐Specific Genetic Variation, and the Rare Occurrence of Inter‐Specific Hybrids in the Wild

Interspecific and Intraspecific Genetic Diversity of Thunnus Species

The genus Thunnus contains eight valid species with a fossil record extending back to the Middle Eocene, about 40 million years ago (Carrol, 1988, Benton, 1993). Collette (1978) distinguished tunas into the temperate subgenus Thunnus (bluefin tuna group) and the tropical subgenus Neothunnus (yellowfin group) by the presence or absence of a central heat exchanger. The yellowfin group contains bl...

phylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran

in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...

Budding Compatibility of Almond and Plum on Some Wild Species and Interspecific Hybrids of Almond

Interspecific and intraspecific variation in cercariae release.

Given the importance of temperature for the shedding of trematode infective stages (cercariae) from gastropod first intermediate hosts, we investigated the response to temperature increases of trematodes of the intertidal snail Zeacumantus subcarinatus collected from different latitudes (differing in mean annual summer temperature) on the South Island of New Zealand. We investigated whether she...

PyroClean: Denoising Pyrosequences from Protein-Coding Amplicons for the Recovery of Interspecific and Intraspecific Genetic Variation

High-throughput parallel sequencing is a powerful tool for the quantification of microbial diversity through the amplification of nuclear ribosomal gene regions. Recent work has extended this approach to the quantification of diversity within otherwise difficult-to-study metazoan groups. However, nuclear ribosomal genes present both analytical challenges and practical limitations that are a con...
