J.D. Anderson 1958 Ambystoma m. croceum March 1 1/2 mi NW Ellicott RR Sta, 4 mi W Watsonville, Santa Cruz Co, Calif Renaud's tenebris under large logs. I have now under a pile of old fence pickets with an adult Geneices lugubris - first time I've seen the two together. 1 saw Geneices seen nearby. Soil samples taken at copse - March 30. Valencia lagoon, Rio del Mar, Santa Cruz Co, Calif. Series of larvae taken at the NW end of the pond using long handled dip nets. As usual best success resulted from working in water 6 - 12" deep near clumps of vegetation with some open water surrounding the clumps. Had least results I've given had working near clumps of Potamogeton. This may be because the Ellobiaria is later in getting's started. Thermal data: temps recorded for 14 minute ranged between 13.0 + 13.5° C. Time 10:30 - 11:30 am. Light rain falling, by dark with heavy clouds. Ostracoda in tremendous numbers; Rotatoria & Copepods common but not yet at pond; no ; Conchostraca present but not numerous. Hyla x long tadpoles very abundant. seem to be more Ambystoma larvae than in previous years. March 30 1/2 mi NW Ellicott RR Sta, 4mi W Watsonville Santa Cruz Co, Calif Worked fringes of Ellicott Pond for almost two hours with R. Graham. Dip netted all around the pond & took only 1 larvae (A. m. croceum). Don't quite understand why since conditions seem ideal.
