Shrews of the La Sal Mountains, southeastern Utah

We conducted a trapping survey of small mammals along an elevational gradient in the La Sal Mountains and documented 4 species of shrews ( Sorex ), the largest number inhabiting any mountain range in Utah. Sorex palustris was restricted to very moist microhabitats near open water at mid- to high elevations where it was relatively common. Occurring in nearly all habitats across the entire sampling gradient, S. monticolus was the numerically dominant small mammal at many sites. Sorex nanus , a new record for the La Sals, was found in areas of rockfall at high elevations and in a rocky wash at mid-elevation. Sorex cinereus , a new record for southeastern Utah, was recorded at a single high-elevation locality. Most localities had 2 syntopic species of shrews, and at 1 site in and around a rockslide we recorded all 4 species. Despite their current isolation, the La Sal Mountains support a remarkably diverse shrew fauna. Their proximity to the main southern Rocky Mountains as a rich faunal source and the presence of abundant rockfall microhabitat appear to be important causal factors.     

A new cavehopper (Amphipoda: Talitridae) from lava tubes in La Palma,Canary Islands

Only two cavernicolous talitrids were known from the entire world. A third species, belonging to a new genus, discovered in lava caves of the island of La Palma (Canary Islands) is described herein. Cave adaptations consist of lack of body pigments, small and partly depigmented eyes, and great elongation of the appendages. This amphipod is the fifth terrestrial troglobite described from La Palma; twelve other obligatory cavernicoles, partly undescribed, are also known from the island.     

Classical Biological Control of Bemisia tabaci in the United States. By Juli Gould,Kim Hoelmer & John Goolsby

ABSTRACT

The present study describes two new genera, six new species and three new records from the Sea of Marmara. The new genus Marmara gen. nov. belonging to the family Sagartiidae is mainly characterized by having conspicuous muscular belts along the column and the absence of suckers and tenaculi on the body wall. The genus Charisactis gen. nov. belonging to the family Condylanthidae is mainly characterized by having an atypical mesentery arrangement, single siphonoglyph and homotrichs in tentacles. The other species newly described from the Sea of Marmara belong to the families Diadumenidae (one species from deep waters), Halcampoididae (one species from shallow waters), Edwardsiidae (one species from shallow waters) and Epizoanthidae (one species from deep waters). Three species, namely Epizoanthus arenaceus (family Epizoanthidae), Rolandia coralloides (family Clavulariidae) and Virgularia sp. (family Virgulariidae) are reported for the first time from the Sea of Marmara. The external and internal anatomical features as well as cnidom structures of the species are presented and discussed with the closely related species. http://www.zoobank.org/urn:lsid:zoobank.org:pub:51DA9869-D786-4A8A-8C1F-62DC1BB67923     

The scolopendromorph centipedes of St John,U.S. Virgin Islands collected by Dr W. B. Muchmore

A collection of scolopendromorph centipedes from the U.S. Virgin Islands is described. It comprises five species Scolopendra alternans, Cormocephalus impulsus sp. nov., Otostigmus (Parotostigmus) caraibicus, Newportia longitarsis virginensis subsp. nov., and Cryptops neocaledonicus muchmorei subsp. nov.     

Rozella Pearl Beverly Blood Smith, 1911-1887

The life, activities, and contributions of an energetic, catholic woman scholar, Rozella B. Smith, are reviewed. Her pioneer innovations in bibliographic data retrieval and mapping by use of the computer, creating a permanent niche for her in the annals of herpetology, are emphasized. A list of her publications is included.     

In memoriam: Seville Flowers (1900-1968)

Seville Flowers was the foremost authority of his time on cryptogamic botany in the intermountain region, having published monographs on the mosses, lichens, and ferns of Utah. He also had strong interests in algae, grasses, composites, and the history of botany. In addition to his systematic research, his expertise extended to field ecology. Early in his career he made a classic study of the vegetation of the Great Salt Lake region that led in later years to his participation in the ecological studies at Dugway Proving Grounds in western Utah. Still later he had charge of the predam vegetative surveys of several reservoir sites along the Upper Colorado River, including Glen Canyon, which was later submerged under Lake Powell. He served as professor of botany at the University of Utah from 1936 to 1968. His professional career started in 1929. A bibliography of his writings is included in this account of his life and professional career.      

In memoriam: William Wallace Newby (1902-1977)

W. W. Newby, professor of biology at the University of Utah from 1927 to 1971, was renowned as a great teacher and a clear and forceful writer and for his meticulous research in invertebrate embryology. Ancillary skills were counseling (especially of premedical students), illustrating, wood crafting, and paper preserving. Some of his writings pertained to the history of research in the biological sciences at the University of Utah. His specialty areas in teaching were embryology and genetics, and he served as chairman of the Department of Genetics and Cytology from the year of its creation in 1948 until 1962. The most outstanding example of his research pertained to the early embryology of the echiuroid worm Urechis caupo .         

Human fatalities caused by venomous animals in Utah, 1900-90

An examination of death certificates at the Utah Bureau of Health Statistics from 1900 through 1990 indicates that Utah has a very low incidence of human fatalities due to venomous bites and stings. During this 91-year period, 20 fatalities were recorded from bee (10) or hornet (1) stings, spider bites 94), and rattlesnake bites (5). There were eight additional fatalities during the early part of this century recorded "insect bite," "apparently insect bite," or "unknown agent poisoning," some of which may have included spiders. No deaths were recorded from Gila monster or scorpion evenomizations, although in 1962 one death in San Juan County was recorded as "venom poisoning, unknown agent, possible scorpion." Utah statistics follow the natural pattern, indicating that bee stings cause more fatalities than spider or rattlesnake bites. Raid deaths (within minutes) occurred in the majority of bee sting fatalities, resulting from allergic reactions (anaphylaxis), whereas protracted death times of days or months, resulting from infection, followed most spider or unknown insect bites. Only two spider bite fatalities occurred 1-3 days, suggesting black widow envenomization. Two of the five fatalities from rattlesnake bite resulted from handling the offending snake, one fatality was recorded as a homicide, and one other envenomization occurred in Arizona, with subsequent death in Utah.
