Field Studies of Ceanothus leucodermis Chaparral Burned Sites in California Populations of the chaparral shrub were sampled in southern California and further north in Monterey and Santa Clara counties and it was discovered that postfire regeneration modes were different. The southern California populations had substantial resprouting with some seedling recruitment. The Monterey populations had no resprouting ability and recovery was entirely by seedlings. However, there is an age effect in that when young these northern California populations fail to recruit seedlings due to lack of a seed bank buildup in the short interval since the last fire. These populations likely will be extirpated. I hypothesize that this obligate seeding mode has been selected for because seed reproduction is more...

Sequences were generated from metacercariae samples at U.S. Geological Survey National Wildlife Health Center (NWHC) and compared for base pair similarities with publicly available sequences from GenBank using BLAST (https://blast.ncbi.nlm.nih.gov/Blast.cgi). Selection of GenBank sequences to include in the .msf file was based on the number of base pair similarities (94% or higher identity to this study’s sequences), 98–100% coverage AND stage of parasite from which the sequence was generated. An excel file listing all parasites and DNA from NWHC vouchered with the University...
