Mid-Tertiary isopach and lithofacies maps for the Los Angeles region, California: Templates for palinspastic reconstruction to 17.4 Ma
Thane H. McCulloh, Larry A. Beyer
2004, Professional Paper 1690
A preliminary palinspastic reconstruction is presented of the region of the Los Angeles Basin at its 17.4 Ma inception. To create this reconstruction, pertinent paleomagnetic declination data are combined with new maps of the areal extent, thickness variations, and depositional facies of the >17.4 Ma Sespe-Vaqueros Formations and their equivalents.Opening...

Testing hypotheses for excess flower production and low fruit-to-flower ratios in a pollinating seed-consuming mutualism
J. Nathaniel Holland, Judith L. Bronstein, Donald L. DeAngelis
2004, Oikos (105) 633-640
Pollinator attraction, pollen limitation, resource limitation, pollen donation and selective fruit abortion have all been proposed as processes explaining why hermaphroditic plants commonly produce many more flowers than mature fruit. We conducted a series of experiments in Arizona to investigate low fruit-to-flower ratios in senita cacti, which rely exclusively on...
