Neighbors who were closer to Patty than the Paulsens reported that Miss Bianca had left her little mouse house, on a minor lake near Grand Rapids, exclusively to Walter and not to his two brothers.
Here, even rather minor lake level fluctuations must have displaced littoral populations, which were forced to follow the shifting shoreline, and thus induced admixture of several previously isolated populations.
Mitochondrial phylogeographic patterns retained signals of large-scale migration events triggered by major lake level fluctuations, whereas the genetic cohesion among local groups of populations indicated by AFLP data results from gene flow between adjacent populations brought about by relatively frequent minor lake level fluctuations.
Mitochondrial phylogeographic patterns retained signals of large-scale migration events triggered by historical, major lake level fluctuations, whereas AFLP data indicated genetic cohesion among local groups of populations resulting from secondary contact of adjacent populations in the course of the more frequently occurring, minor lake level fluctuations.
The scientists stumbled on the new species after the minor disapointment of checking out a small lake for waterlilies and finding none there.
The ice margin depositional systems are characterised by coarse-grained deltas and subaqueous fans, which are formed by stacked transgressive regressive sequences, recording an overall lake transgression, interrupted by minor short-term lake-level falls.
Eastern Anatolia during the 9th 8th centuries bc was occupied by the state of Urartu, at first a minor kingdom centred on Lake Van but later extended to include parts of what are now Armenia, Iranian Azerbaijan, and Kurdistan in northern Iraq.
Our investigation of pollen assemblages and modern vegetation distribution suggests that the fossil pollen in the Gonghai Lake sediments mainly represents the vegetation composition of the area surrounding the lake, with only a minor contribution (<10%) from vegetation farther than 5 km from the lake (Supplementary Text S1).
Because the lake is so shallow, even minor drops expose much more land around the lake.
