Monitoring Western Australia's Rangelands, Ron Hacker, David Beurle, George Gardiner
Journal of the Department of Agriculture, Western Australia, Series 4
Rangelands, native pastures used for grazing domestic livestock, occupy about 100 million hectares or 40 per cent of Western Australia, extending from the tropical grasslands of the Kimberley to the arid shrub steppe of the Nullarbor Plain.
The rangelands are characterized by highly variable seasonal conditions. Carrying capacity can fluctuate dramatically from year to year. Grazing management requires a tactical approach from one season to the next because of the great variation in the capacity of the land to support stock.
Rangeland monitoring provides pastoralists with objective information on these changes to assist their management decision making. The Western Australian …
Aquatic Macroinvertebrates Of The St. Francis Sunken Lands In Northeast Arkansas, Betty G. Cochran, George L. Harp
Aquatic Macroinvertebrates Of The St. Francis Sunken Lands In Northeast Arkansas, Betty G. Cochran, George L. Harp
Journal of the Arkansas Academy of Science
The primary objective of this study was to survey the aquatic macroinvertebrate diversity of the St. Francis Sunken Lands in northeast Arkansas. Secondary objectives were a determination of their relative abundance and distributional and seasonal patterns. Sixty semi-annual collections were made from 30 stations by sampling each station 2 times for 1 ½ man-hours with a Turtox Indestructible™ dip net. Totals of 243 taxa and 13,952 organisms were recorded for the sample period (August 1987 - July 1988). Each station was assigned to 1 of 4 associations, distinguished by distinct physical factors within the river channels and the immediate watershed. …

Reproductive Phenophases And Clutch Characteristics Of Selected Arkansas Amphibians, Stanley E. Trauth, Robert L. Cox Jr., Brian P. Butterfield, David A. Saugey, Walter E. Meshaka Jr.
Journal of the Arkansas Academy of Science
Seasonal reproductive phenomena in 13 species of salamanders and 16 species of anurans from Arkansas were investigated. Most specimens were collected during a span of 6 years (1985-1990). Clutch characteristics, including mensural and meristic data, were determined from gravid females. In some species, the size of egg masses was also documented. Among the plethodontid salamanders, average clutch size (in parentheses) was greatest in Eurycea lucifuga (77.7) and smallest in Plethodon serratus (7.0). One of 2 ambystomatid salamanders (Ambystoma texanum) averaged 545.4 eggs per clutch; the other species (Ambystoma tigrinum) averaged 1 30.5. Siren intermedia nettingi (one of 3 large salamanders …
