Genetic diversity of allozymes at 24 loci was studied in 23 populations of longleaf pine (Pinus pa/u.stris Mill.). including three seed orchard populations and an old-growth stand. Overall, the mean number of alleles per polymorphic locus was 2.9, the percentage of polymorphic loci was 92%. and the mean expected heterozygosity was 0.105. These values are comparable with diversity measures found...

A new analysis method is introduced for investigating whether major flares are clustered in certain fixed regions of the Sun in rigidly-rotating coordinate systems. This method is applied to analysis of major flares of solar cycles 19–23. Northern and southern hemispheres are separately analyzed, and it is found that longitude distributions of flares in the two hemispheres are different. Theref...

[1] Using densities measured by accelerometers on the CHAMP and GRACE satellites, and taking advantage of the local time precession characteristics of these near-polar orbiting satellites, exosphere temperatures are derived as a function of local time, longitude and latitude. Significant longitude variability (e.g., ±25K maximum to minimum over the equator) in geomagnetically-quiet exosphere te...

The Miankaleh Biosphere Reserve with a surface area of 68800 hectares is located in 12 km N of Behshahr (MazandaranProvince, N. Iran) between 53˚ 35' - 54˚ 2' eastern longitude and 36˚ 45' - 36˚ 55' northern latitude. The vegetation of MiankalehPeninsula was studied, using the Braun-Blanquet (Zygmatist) method. Based on the analysis of phytosociological data using the Anaphyto software and AFC ...

Newly hatched sea turtles exposed to artificially generated magnetic fields with parameters characteristic of two sites 3700 km apart, differing only in longitude, can distinguish the two apparent locations and orient appropriately.
