Mammalian Species Origin and Geographical Dispersal Patterns Correlate With Changes in Chromosome Structure, Exemplified in Lemurs (Madagascar) and Bats (Worldwide)
Bats Biogeography Chromosomes Karyotypes Lemurs Speciation
2014/10/22
The origin and geographical distribution of mammalian species (my examples are lemurs and bats) correlate with predictable chromosomal structural changes (KFT=karyotypic fission theory). Chromosome st...
Giant Plagioclase Basalts from Northeastern Deccan Volcanic Province, India: Implications for Their Origin and Petrogenetic Significance
Giant Plagioclase Basalt Crustal Magma Chamber Jabalpur
2013/3/11
The giant plagioclase basalts (GPBs) with plagioclase phenocrysts that reach up to 3 cm in length are found near Jabalpur in the northeastern part of the Deccan Volcanic Province (DVP). The thickness ...
An estimation of groundwater type and origin of the complex karst catchment using hydrological and hydrogeochemical parameters:A case study of the Gacka river springs
hydrogeology karst hydrogeochemistry isotopic research river Gacka Croatia
2009/12/7
Karst aquifers are heterogeneous terrains, where it is hard to assess any hydraulic parameter. Therefore, a multidisciplinary approach is necessary for research on karst aquifers. Catchment area of th...
Origin of the palaeic landforms and glacial impact on the Varanger Peninsula,northern Norway
palaeic landforms glacial impact Varanger Peninsula
2009/12/2
The palaeic surface of the Varanger Peninsula has been studied to evaluate formational processes and glacial remoulding. The peninsula largely consists of a plateau (the palaeic surface) where quartzi...
The number,form and origin of sub-horizontal surfaces in north Ceredigion
number form origin sub-horizontal surfaces north Ceredigion
2009/12/2
The number, form and origin of a stepped sequence of sub-horizontal surfaces in north Ceredigion, U.K., has been the subject of continuing controversy over nearly two centuries of investigation. Renew...
Distribution,origin and cycling of carbon in the Tana River (Kenya):a dry season basin-scale survey from headwaters to the delta
Distribution origin cycling carbon season basin-scale survey headwaters delta
2010/1/21
The Tana River basin (TRB) is the largest in Kenya (~120 000 km2). We conducted a survey during the dry season throughout the TRB, analyzing a broad suite of biogeochemical parameters. Biogeochemical ...
Tree-ring based reconstruction of the seasonal timing, major events and origin of rockfall on a case-study slope in the Swiss Alps
the seasonal timing major events origin of rockfall the Swiss Alps
2009/12/30
The intra-annual position of callus tissue and of tangential rows of traumatic resin ducts was determined in order to reconstruct the seasonality of past rockfall events. Results indicate strong intra...
Nitrous oxide distribution and its origin in the central and eastern South Pacific Subtropical Gyre
Nitrous oxide distribution central and eastern South Pacific Subtropical Gyre
2010/1/14
The mechanisms of microbial nitrous oxide (N2O) production in the ocean have been the subject of many discussions in recent years. New isotopomeric tools can further refine our knowledge of N2O source...
Current life is a complex, multi-level phenomenon that is so diverse in its manifestations that a short and exhaustive definition of life is hardly possible. The high complexity of life, as well as a ...
Possible seismogenic origin of changes in the ULFEM resonant structure observed at Teoloyucan geomagnetic station,Mexico,1999-2001
Possible seismogenic origin changes ULFEM resonant structure Teoloyucan geomagnetic station
2009/12/29
The evolution of the ULF resonant structure observed at Teoloyucan geomagnetic station has been provisionally studied in a possible relation with seismic activity in Mexico in the period 1999-2001. Tw...
