Four different communities and one culture of autotrophic microbial assemblages were obtained by incubation of samples collected from high elevation snow in the Alps (Mt. Blanc area) and the Andes (Ne...
Short term changes in zooplankton community were investigated at a fixed station in offshore waters of the Ligurian Sea (DYNAPROC 2 cruise, September–October 2004). Mesozooplankton were sampled with v...
In recent years mental deficiency policy and the wider issue of the history of people with learning difficulties have attracted much attention. Important publications by Mathew Thomson, Anne Digby, Ma...
Origin of diversity in falling snow     Origin  diversity  falling snow       2008/11/20
This paper presents a systematic way to examine the origin of variety in falling snow. First, we define shape diversity as the logarithm of the number of possible distinguishable crystal forms for a g...
To reduce the risk of privacy disclosure during personal data publishing, the approach of anonymization is widely employed. On this topic, current studies mainly focus on two directions: (1)developin...
Fluid flow related seafloor structures and gas seeps were detected in the North Sea in the 1970s and 1980s by acoustic sub-bottom profiling and oil rig surveys. A variety of features like pockmarks, g...

The plant diversity of southern peninsular India has recently been reduced to a great extent due to anthropogenic disturbance and environmental degradation. Disturbance was the major factor responsibl...
In order to learn the origin of the Chinese Mongolian horse, we analyzed polymorphisms within the mtDNA D-loop variable region in 305 horses of 6 types of 3 different breeds, including one imported br...
In this study, we investigated the genetic diversity and phylogenetic relationship of six duck populations by employing the genetic polymorphisms of 20 microsatellites. The parameters used in this stu...
This study describes genetic variability in the BoLA-DRB3 gene in Iranian native cattle (Bos Indicus and Taurus) and relationships between these breeds. This is the first study of genetic polymorphism...
The genetic structure and diversity of 15 Chinese indigenous chicken breeds was investigated using 29 microsatellite markers. The total number of birds examined was 542, on average 36 birds per breed....
In this study, cattle microsatellite markers recommended for diversity studies of cattle by the EU AIRE 2066 Concerted Action Group were used to study the genetic diversity of 105 Thai swamp buffalo w...
The presence and diversity of free-living dinoflagellates belonging to the endosymbiotic genus Symbiodinium were explored in seawater samples collected above coral reefs in Kaˉne‘ohe Bay, O‘ahu, Hawa...
We analyzed the relationship between population abundance and cell size in phytoplankton assemblages from coastal, shelf, and open-ocean environments. Our results show that across the entire size spec...
