The Effectiveness Of Soap In Preventing Deer Browsing, Michael J. Fargione, Milo E. Richmond
The Effectiveness Of Soap In Preventing Deer Browsing, Michael J. Fargione, Milo E. Richmond
Fifth Eastern Wildlife Damage Control Conference (1991)
A series of bioassays was performed to evaluate the effectiveness of soap and soap components as deer (Odocoi virginianus) repellents. Sweet-corn plots protected with tallow-based soap bars, nontallow bars, and those sprayed with commercial repellent Hinder”, experienced significantly reduced browsing compared with untreated plots. Damage top protected with tallow-based soap was less than damage to nontallow soap plots, while Hinder”-treated plots had intermediate damage. In a second bioassay, 2 spray applications of soap were found to be as effective as soap bars in preventing browsing native vegetation over a 126-day period. The addition of perfume did not enhance …

Univariate and multivariate analyses of 20 skull characters of 304 adult sea otters from throughout the geographic range strongly suggest that three subspecies should be recognized. The nominate form, Enhydra lutris lutris, occurs from the Kuril Islands north to the Commander Islands in the western Pacific Ocean. Individuals of E. l. lutris are characterized by large size and wide skulls with short nasal bones. E. 1. nereis is found along the California coast and off San Nicolas Island, where the species recently has been reintroduced from coastal California. Specimens of E. 1. nereis have narrow skulls with a long …
Evolution Of The Aeluroid Camivora: Viverrid Affinities Of The Miocene Camivoran Herpestides, Robert M. Hunt Jr.

Although the time of origin of viverrid and hyaenid carnivorans has not been clearly documented in the fossil record, their theater of evolution has long been established by a mid-Cenozoic fossil distribution entirely confined to the Old World. Recent examination of the basicranial morphology of important early aeluroid crania from Europe and Asia significantly alters earlier views of viverrid and hyaenid origins. The early Miocene carnivoran Herpestides antiquus, considered a potential ancestral hyaenid or herpestid in earlier studies, is identified as a true viverrid on the basis of a large sample of skulls of both juveniles and adults from …
Additional Fossil Evidence On The Differentiation Of The Earliest Euprimates, Kenneth D. Rose, Thomas M. Bown
Additional Fossil Evidence On The Differentiation Of The Earliest Euprimates, Kenneth D. Rose, Thomas M. Bown

Several well-preserved jaws of the rare North American omomyid primate Steinius vespertinus, including the first known antemolar dentitions, have been discovered in 1989 and 1990 in the early Eocene Willwood Formation of the Bighorn Basin, Wyoming. They indicate that its dental formula is as primitive as those in early Eocene Donrussellia (Adapidae) and Teilhardina (Omomyidae) - widely considered to be the most primitive known euprimates - and that in various dental characters Steinius is as primitive or more so than Teilhardina. Therefore, despite its occurrence at least 2 million years later than Teilhardina, S. vespertinus is the …
Evolution Of The Aeluroid Camivora: Hyaenid Affinities Of The Miocene Camivoran Tungurictis Spocki From Inner Mongolia, Robert M. Hunt Jr., Nikos Solounias

Among the mammalian fossils discovered in were crania and mandibles of rare carnivorans, 1930 by the Central Asiatic Expedition of the including the first complete skulls of several Asian American Museum of Natural History (New York) mid-Miocene lineages. Most of these fossils came in the Tung Gur Formation of Inner Mongolia from a single locality termed Wolf Camp Quarry that produced, among other striking finds, a small fox-sized cranium referred to a new genus and species Tungurictis spocki Colbert 1939. Today this remains the only known cranium of Tungurictis yet discovered. Preparation and reinterpretation of the auditory region demonstrate that …
