Using vodka to further science: The micro-photography of Ian Gardiner

E-Fauna photographer Ian Gardiner has taken 10th place in the Nikon Small World photomicrography contest with a photo of a clam shrimp from Alberta. 

According to the news release:  "Gardiner's detailed portrait of a clam shrimp from the Alberta Prairie was recognized in the Nikon Small World Photomicrography Competition. His profile of a five-millimetre-long female with eggs was the only Canadian entry that placed, finishing 10th, in October."   In the news release, Ian expanded on his technique for photographing these tiny crustaceans:  "I give them a small shot of vodka, which kind of keeps them quiet so I can photograph them,"

E-Fauna BC freshwater mollusc editor Ian Gardiner has done it again.  Earlier this month, he discovered a new crayfish species for BC, and now he has discovered another new species for BC--the Smoothlip Fairy Shrimp (Eubranchipus intricatus).  Ian photographed and collected this tiny crustacean from two temporary sloughs near Jaffray BC in the Kootenays.  His find is a first for BC and specimens have been sent to the Royal BC Museum for their collection.

Ian indicates that this species of fairy shrimp is found in temporary pools of low salinity and its range in North America is limited to Alberta, Saskatchewan, Manitoba, Nova Scotia, Montana, Minnesota, Wyoming and Massachusetts.

Mapping Update 2015

The interactive GIS mapping available on E-Flora and E-Fauna BC has been updated with new, easy-to-use software. Visit our full-size GIS maps to view new features, easy-access legends, and additional map tools.  We have added special zoom features to regions of interest, and map coordinates are now readily visible.  We will continue to add features to the maps, including additional biogeographic layers.

As an additional bonus, we have now added the ability to view map data (the data behind the distribution dots) from both the full-size maps and from the small maps on the atlas pages.

New Crayfish Species Documented in British Columbia: Northern Crayfish (Orconectes virilis)

Northern Crayfish (Orconectes virilis), photo  by Ian Gardiner

The Northern Crayfish (Orconectes virilis) has been documented in British Columbia for the first time.  E-Fauna BC freshwater mollusc editor and photographer Ian Gardiner has both photographed and collected this species in the East Kootenays.  Until Ian's work, BC had only one reported crayfish species, the Signal Crayfish (Pacifastacus leniusculus), which occurs further to the west in BC.   

In describing his find, Ian says:  "Informal reports of crayfish in the Kootenays, east of the known range of the Signal Crayfish, have occurred in the popular outdoors press and on internet sites but without reference to any particular species. In 2014 and 2015, this author both collected and photographed specimens of the Northern Crayfish in the east Kootenays. It was documented at the following sites: 1) a pond 3.2 km SW of Grasmere, BC 2) Loon Lake, 1.8 km NW of Grasmere, BC."

"There appears to be no reference in the formal literature to the occurrence of Northern Crayfish in British Columbia. The E-Fauna BC photographic documentation and specimens collected by the author, from the East Kootenays just north of the US border, would seem to be the first confirmation of this species in British Columbia."
