date of photo between 2000 and 2002
location
Large River Bar at Park along Trinity River (Trinity County, California, US)family
Helminthoglyptidae
order
Stylommatophora
class Gastropoda
habitat This one under debris on large river bar , with sand, cobble and small-boulder-dominated substrates, some downed wood . Just abonotes HAVING LUNCH WITH TOM KIRK ALONG TRINITY RIVER ON WAY TO TASS OR RETRO SALAMANDER SURVEY SITE, I TURNED A SMALL BOULDER AND FOUND HELMINTHOGLYPTA , I THINK HERTLEINI SP. I CHECKED MY IDENTIFICATION ALONG WITH DISTRIBUTION IN PILSBURY 1930-19940'S CHECKLIST FOR CALIFORNIA BY INGRAM (1946: BULLETIN SOUTHERN CALIFORNIA ACADEMYS OF SCIENCES, VOLUME 45, PART 2: PAGES 61-93; THIS ONE FOUND OFF HIGHWAY 299, WITHIN 10 MILES OF HUMBOLDT /TRINITY COUNTIES LINE ON TRINITY SIDE. PAST THE BRIDGE AT COUNTY LINE. TRYING TO GET TO MANZANITA RIDGE TRAIL . SUCCESSFUL DAY AND YEAR FOR HERPETOLOGY & MOLLUSK SURVEYS FOR TOM KIRK & MYSELF FOR SURE! THIS COULD BE A NEW SUBSPECIES BECAUSE PILSBURY'S LIST HAS CYPREOPHILA & HERTLEINI IN OUT-LYING AREAS BUT NOT REALLY HERE AND THE PRESENT LIST HAS A SUBSPECIES FOR PRACTICALLY EVERY AREA IN CALIFORNIA AT THAT TIME. LIKE I TOLD TOM KIRK IN 1996- EVERY WATERSHED WILL BE GENETICALLY AND/OR PHENOTYPICALLY DISTINCT, OR A COMINBINATION THEREOF, WITH RESPECT TO THEIR DEGREE OF REPRODUCTIVE ISOLATION OVER THE POPULATION STUDIED, GIVEN THE TYPES OF GEOLOGICAL, HYDROLOGICAL, AND OTHER ENVIRONMENTALLY SIGNIFICANT PARAMETERS (BOTANICAL ASSEMBLAGE, IN CONJUNCTION WITH CLIMATIC FACTORS OBSERVED OVER THIS MOST-RUGGED TERRAIN OF THE KLAMATH-SISKIYOU BIO-REGION AS DEFINED BY WELSH, AND WITH RESPECT TO RESTrICTION IN RANGE AND MOBILITY AND THEREFORE GEOGRAPHICAL ISOLATION OF WATERSHED DEPENDANT POPULATIONS, AS IN RHYACOTRITON OR HELMINOGLYPTA, IS TO BE EXPECTED, ESPECIALLY WITH PLASTIC SPECIES.camera NIKON DIGITAL
