 Recent News in Evolutionary Biology at SDSU

September 2013:

Dr. Richard Etheridge, Emeritus Professor of Biology at SDSU, recently co-authored a paper:
   Lobo, Fernando and Richard Etheridge. 2013. The type locality of Phymaturus palluma (Molina, 1782) (Reptilia: Iguania: Liolaemidae) and the status of Phymaturus adrianae Pereyra, 1992 and other unnamed populations.
South American Journal of Herpetology 8(2): 89-101.

In this paper, they deduced the type locality of a lizard originally collected by Charles Darwin during his expedition on the HMS Beagle! Richard Etheridge explains here:

    In 1845 Thomas Bell of the British Museum of Natural History published descriptions of all of the reptiles that had been collected by Charles Darwin during his Voyage of the Beagle and later donated to the museum. There were many new species in the collection, and one specimen, a large lizard with a spiny tail, that Bell described as a new genus and species. Although the localities where Darwin  had collected his specimens were provided for most the other species, no locality was given for the spiny-tailed lizard. When I began my field work in Argentina in 1983, only one additional species had been described in his genus. Today there are 41 species, all of them found at moderate to high elevations and all of them viviparous. Most of Darwin’s specimens came from localities at or near the costs of Argentina and Chile. The only exceptions were those collected during his journey by horseback from Santiago, Chile eastward over the high Andes into Mendoza province in Argentina and return to Santiago by a different route.
    Fortunately the publication of his field notes by Chancellor and Van Wyhe is 2009 provided us with a day-by-day account of this trip. We found that on March  24, 1835, at a place called Cordon del Portillo, at an elevation of 2000 m., Darwin wrote that he had captured a viviparous lizard, with a brief description of its color pattern, and that it had been “killed by a blow of hammer” and that “young are soon protruded.” This is his only mention of having collected a lizard during this trip. At our request the Curator of Reptiles at the British Museum examined the specimen and replied that “I can confirm that there is indeed a definite break in the skin which may well have been caused by the strike of a hammer. There is quite a large hole in this position. I also can confirm that by feel the skull is quite cleanly broken.” Additionally, An adult male and female have recently been collected at the type locality and in all respects can be regarded as belonging to the same species as the types specimen in the British Museum. Thus we are quite confident that Cordon del Portillo, high in the Andes of Argentina is indeed the locality where Darwin collected the type specimen of this genus.


August 2013 :

The SDSU Herbarium (LS 267, Life Science South) joins the Southwest Environmental Information Network (SEINet), a consortium of numerous herbaria of the southwestern United States. This database allows searches of all (worldwide) records by scientific name, herbarium, county, locality, collector, date of collection, and accession number. All records are displayed, and those that are geo-referenced may be mapped in several different formats. Our herbarium has over 21,000 specimens of plants, all of which are databased, and 89% of which are from California. The California records are also accessible through The Consortium of California Herbaria (CCH), organized through UC-Berkeley.


November 2012:

We are saddened to report that Dr. Ted Cohn, Emeritus Professor of Biology at SDSU, died of complications from surgery on 25 November 2012 in Ann Arbor, Michigan. Ted was a valued member of our faculty. His academic research was focused on insect systematics, particularly of the western US and Mexico. He generously contributed to the Roger Carpenter Lecture in Comparative Biology over the years, and some time ago we named our graduate scholarship in his honor: the Ted Cohn Evolutionary Biology Scholarship. In his retirement, Ted and his wife Jean lived half the year, and later full-time, in Ann Arbor, Michigan, where Ted continued his research efforts at the University of Michigan Museum of Zoology. A synopsis of Ted's life there is written here.

Ted was a wonderful, delightful person. He will be sorely missed by all who knew him.
