    Quick Guide for the Identification of Maryland Scarabaeoidea Mallory Hagadorn Dr. Dana L. Price Department of Biological Sciences Salisbury University This document is a pictorial reference of Maryland Scarabaeoidea genera (and sometimes species) that was created to expedite the identification of Maryland Scarabs. Our current understanding of Maryland Scarabs comes from “An Annotated Checklist of the Scarabaeoidea (Coleoptera) of Maryland” (Staines 1984). Staines reported 266 species and subspecies using literature and review of several Maryland Museums. Dr. Price and her research students are currently conducting a bioinventory of Maryland Scarabs that will be used to create a “Taxonomic Guide to the Scarabaeoidea of Maryland”. This will include dichotomous keys to family and species based on historical reports and collections from all 23 counties in Maryland. This document should be cited as: Hagadorn, M.A. and D.L.

To assess their distribution in North America, I created a checklist of over 300 beetle species known to colonize dung (Chapter 2). To assess the affect of habitat and location on dung beetle diversity, I conducted sampling at Purple Springs Grazing Reserve and Cypress Hills Interprovincial Park (Chapter 3). Each habitat and location was dominated by different species for both sampling years. The affect of bait treatment and age on the attractiveness of the coprophagous insect community was assessed using fresh and frozen dung baits, with frozen baits being more attractive for the first three days (Chapter 4).

  • Effects of Off-Road Vehicles on the Biota of the Algodones Dunes, Imperial County, California
    0042778 Journal of Applied Ecology (1983), 20, 265-286 EFFECTS OF OFF-ROAD VEHICLES ON THE BIOTA OF THE ALGODONES DUNES, IMPERIAL COUNTY, CALIFORNIA BY ROGER A. LUCKENBACH* AND R. BRUCE BURY Denver WildlifeResearch Center, U.S. Fish and Wildlife Service, 1300 Blue Spruce, Fort Collins, Colorado 80524, U.S.A. SUMMARY (1) The Algodones Dunes, the largest dune complex in California, contains many unique species. This dune system also receives the greatest use by off-road vehicles (ORVs). (2) Studies of paired plots (unused v. ORV-used) and animal tracks along sand sweeps clearly demonstrate that ORV activities in the Algodones Dunes significantly reduced the biota. (3) There were marked declines in herbaceous and perennial plants, arthropods, lizards and mammals in ORV-used areas compared with nearby controls. All sand-adapted species, including several plants considered rare or threatened species, were greatly reduced in habitats where ORVs operate. (4) The biota was negatively affected even by relatively low levels of ORV activities. Areas heavily used by ORVs had virtually no native plants nor wildlife. INTRODUCTION Sand dune areas constitute only 7% of the California Desert. They are disjunct in distribution and function as habitat islands for a variety of arenicolous plant and animal species. Although California sand dunes are generally geologically young (post-pluvial in age), some species are restricted to them and many species in the resident biota show distinctive adaptations. Study of these organisms provides an understandingof the nature of adaptations to extremes of temperature,drought, intense sunlight, and locomotion on a soft substrate. The Algodones Dunes (also known as the Imperial Sand Hills) in Imperial County in south-eastern California are one of the driest and hottest regions in the United States and representone of the most severe environmentsinhabited by plants and animals.

Supercooling point is highly correlated with altitude and SCP frequency distributions show clear physiological variability in C. h. hidalgoensis among populations and within the population Keywords: Cold hardiness inhabiting the highest site. In the latter, SCP frequency was clearly bimodal, indicating the presence of Crystallization temperature two different groups of individuals, and thus a mechanism with two different states of cold hardiness. Environmental change Populations and individuals of C. humectus hidalgoensis were a wide physiological variability with Physiological diversity a relatively broad range of thermotolerance responses to semiarid cold conditions. The study of Scarabaeidae ecophysiological traits in different populations of this species contributes to a more realistic picture of its potential distribution by providing more complete information on the thermal niche.
