Venezuelan Nycteribiid Batflies (Diptera: Nycteribiidae), Lindolpho R. Guimarães

Brigham Young University Science Bulletin, Biological Series

Eleven species of Nycteribiidae, all belonging to the genus Basilia, are reported from Venezuela. Of these, two (tuttlei and typhlops) are described as new and four (anomala, dubia, juquiensis, and tiptoni) are recorded for the first time. B. anomala is the first species with three tergal plates to be found in South America. Synonymies, previous localities, and host records are given for all species, as well as new records and comments. Geographical distribution and host-parasite associations are discussed. Field parties of the Smithsonian Venezuelan Project obtained the material on which this paper is based.

The Hyobranchium And Throat Myology Of The Adult Ambystomidae Of The United States And Northern Mexico, John E. Krogh, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The 16 species and subspecies of the Ambystomidae of the United States are placed into six groups according to their throat morphology as follows: The Dicamptodon group, the Rhyacotriton group, the A. Annulatum–A. cingulatum group, the A. gracile-A. jeffersonianum-A. mabeei-A. macrodactylum-A. maculatum group, the A. talpoideum group, the A. opacum-A. texanum group, and the A. rosaceum-A. t. tigrinum-A. t. melanostictum-A. t. nebulosum group. Dicamptodon appears to be the most primitive group and Rhyacotriton the most specialized. Based on the morphology of the throat region it is suggested that A. rosaceum be placed in the tiger salamander group as a subspecies …

Understory Characteristics Related To Site Quality For Aspen In Utah, James H. Warner, Kimball T. Harper

Brigham Young University Science Bulletin, Biological Series

An analysis has been made of the basic ecology of aspen forests of the mountainous areas of Utah and northern Arizona. Forty-nine study areas have been examined in respect to density, height and age of the tree cover, tree reproduction, and composition and biomass production of the understory. A graphic model of interspecific assocations among prevalent understory species has been prepared by a cluster-analysis procedure based on presence and absence of species in 1,225 small quadrats (0.25 m²) uniformly distributed among the 49 stands. The model separates species of relatively stable as opposed to rapidly seral aspen forests. …

Ecology Of Sceloporus Occidentalis Longipes Baird And Uta Stansburiana Stansburiana Baird And Girard On Rainier Mesa, Nevada Test Site, Nye County, Nevada, Wilmer W. Tanner, James M. Hopkin

Brigham Young University Science Bulletin, Biological Series

This paper constitutes the first in a series of terminal reports to the United States Atomic Energy Commission for Contract AT (11–1) 1496. It includes a major study on the ecology and life history of Sceloporus occidentalis longipes Hollowell and a comparative study of three populations of Uta s. stansburiana Baird and Girard with special emphasis given for the Uta population on Rainier Mesa.

The study plot of major concern in this report is located on Rainier Mesa of the Nevada Test Site. Reports for other study plots (Frenchman's Flat–four study areas–and Mercury Valley ) will follow in the near …

Fisheries Report No 11 - The Fauna, Flora And Planned Usage Of The Dampier Archipelago, A. A. Burbidge, R. I. T. Prince

Fisheries Research Reports

The Dampier Archipelago is a group of islands off the north west coast of Australia (20 20! - 20 45'S, 116 Cast . 117°E), first discovered by William Dampier in 1699 and subsequently named after him by the Baudin expedition of 1801. This name has since been applied by some authors to include all islands from Roebourne to North West Cape, including both Barrow Island and the Monte Bello Islands, but it is more correctly applied to those islands within a 30 mile radius of the town of Dampier.

Ir. recent times, three parties have visited the Archipelago and examined …

Farm Grazing Levels, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

Stocking rates in many dairying areas are so low that the Division has established nine grazing level demonstrations in various areas.

Their aim is to demonstrate that higher stocking rates are practical on existing farms.

Reproductive Wastage In Sheep On Clover Areas, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

Western Australia's 67 per cent lambing for 1970 compares poorly with that of other Australian States, and other countries. From the 12.3 million ewes mated in this State's agricultural areas in 1970, only 8.2 million lambs were marked.

This low 77.7 per cent conception rate sparked the present series of reproductive wastage investigations by the Department's Sheep and Wool Branch.

This report describes the first year's results of the project in W.A.'s "clover disease" areas.

Wimmera Ryegrass Toxicity, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

Wimmera ryegrass toxicity has been reported for many years to affect sheep and occasionally cattle in New Zealand, South Australia and the United States of America.

In Western Australia, occasional reports since 1959 and severe outbreaks of staggers in the Katanning- Gnowangerup areas over the last two years prompted the investigation reported below.

Kimberley Research Station Review Of Progress, 1968-71, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

The potential for harnessing northern rivers flowing to the Gulf of Carpentaria and the Timor Sea was realised many years ago.

These rivers together are estimated to carry about three times the water transported annually over the Murray drainage system and the South Eastern slopes, which comprise the closely settled agricultural areas of South Eastern Australia.

The Kimberley Research Station was established in 1946 to investigate the potential for irrigated agriculture in the Ord River valley. This is a review of the Station's sixth progress report which is being published as Department of Agriculture Bulletin No. 3861.
