Spatial variation in transferrin allele frequencies among herds of feral donkeys in Death Valley National Monument, California Spatial variation in transferrin allele frequencies among herds of feral donkeys in Death Valley National Monument, California
Serum proteins were studied to clarify interrelationships of seemingly disjunct herds of feral donkeys (Equus asinus) in the mountains of Death Valley National Monument, California. Sera of 162 donkeys from five localities in the Panamint Mountains were examined by starch-gel electrophoresis to assess polymorphic variation in transferrins. Four homozygous and six heterozygous transferrin

Ecological studies of vesicular arbuscular mycorrhizae in a barrier sand dune Ecological studies of vesicular arbuscular mycorrhizae in a barrier sand dune
An ecological survey of the vegetation of a barrier dune on the south coast of Rhode Island showed Ammophila breviligulata, Solidago sempervirens, Lathyrus japonicus, and Myrica pensylvanica to be the dominant plant species. All plants were mycorrhizal. Six species of vesicular–arbuscular (VA) fungi occurred in association with these plants, with Gigaspora gigantea and Acaulospora...

The status and distribution of ants in the Crater District of Haleakala National Park The status and distribution of ants in the Crater District of Haleakala National Park
The Crater District of Haleakala National Park was surveyed for ants. Three species were found. Argentine ants (Iridomyrmex humilis) occurred only within I km of the park headquarters and the nearby research facility. Hypoponera opaciceps was found in small numbers throughout the Crater District. Cardiocondyla emeryi was present only at the head of Kaupo Gap. Possible impacts of these...

Procedures for the use of aircraft in wildlife biotelemetry studies Procedures for the use of aircraft in wildlife biotelemetry studies
This is a report on the state of the art methodology and on questions that arise while one is preparing to use aircraft in a biotelemetry study. In general the first step in preparing to mount an antenna on an aircraft is to consult with a certified aircraft mechanic. Aircraft certification is discussed to provide background information concerning the role of the Federal Aviation...

Estimating bird damage from damage incidence in wine grape vineyards Estimating bird damage from damage incidence in wine grape vineyards
Bird damage was measured during 1977 and 1978 at 32 wine grape vineyards in the San Joaquin Valley and North Coastal Region of California. Both the percentage bird loss (PBL) and the percentage of bunches damaged (BDI = bird damage incidence) were determined during 55 total-damage assessments, and the resulting data pairs were used to develop a regression of PBL on BDI. The final...
