RAPD-typing of Central and Eastern North Atlantic and Western North Pacific minke whales, Balaenoptera acutorostrata

Genetic population structure of minke whales Balaenoptera acutorostrata from Greenland, the North East Atlantic and the North Sea probably reflects different ecological regions

“…However, the ES sample was very small and therefore like the Barents Sea (EB) sample poorly represented the allele frequency distribution of the sub-population in question, whereas the differences between the Jan Mayen and North Sea samples appeared to be real. Our finding that samples from Svalbard, the Barents Sea and the northwestern coast of Norway were not genetically different at either the mtDNA or the nuclear level is contradictory to the findings in the RAPD study of Martinez & Pastene (1999). These researchers found indications of the existence of 2 closely related groups of minke whales in the North Atlantic: one in the eastern areas comprising the North Sea, Lofoten-Vesterålen and Barents Sea and another more central group consisting of minke whales from Jan Mayen and Svalbard.…”

“…These researchers found indications of the existence of 2 closely related groups of minke whales in the North Atlantic: one in the eastern areas comprising the North Sea, Lofoten-Vesterålen and Barents Sea and another more central group consisting of minke whales from Jan Mayen and Svalbard. This apparent contradiction can be a result of the different pooling of samples from the various areas, the difference in sample sizes, and the fact that the samples in the present study were taken within the same year, which was not the case in the study by Martinez & Pastene (1999).…”

“…Previous studies applying various genetic techniques found indications of population sub-structuring in North Atlantic minke whales (Palsbøll 1989, Árnason & Spillaert 1991, Danielsdóttir et al 1992, Bakke et al 1996, Martinez et al 1997, Martinez & Pastene 1999. However, as these studies included samples taken in different years, it is unclear to what extent inter-annual variation influenced spatial comparisons.…”

Identification of marine mammal species in food products

“…For ampli®cation, the equipment, 26,27 the ampli®cation programme, 27±29 the composition of the ampli®cation buffer, the DNA polymerase used 23,26,30 and the amount and quality of the DNA 19,21,27,31 need to be optimised. For electrophoresis, the amount and quality of agarose, the composition of the buffer and the length of the gel 28 require standardisation. Once the analysis is standardised in a laboratory, the pa Átterns are usually reproducible.…”

National Green GDP Assessment and Prediction for China Based on a CA-Markov Land Use Simulation Model

“…To reflect the regional characteristics and regional differences in land use changes, according to the existing research [39][40][41], the entire country was divided into four regions-eastern, central, western and northeast-in the process of future land use simulation based on the 16th National Congress of the Communist Party of China. After the land use simulation for each region separately, we used the merging tool in ArcGIS to combine the results so as to obtain the final land use pattern for the entirety of China.…”
