Multivariate analysis of salinity effects on mayfly distributions along a complex river continuum.
(1982)
The association between the benthic community structure and the river gradient as described in the river continuum concept is evaluated in the saline stressed Washita River. Physical, chemical and biological variables were ...
The novelty response of pulse-type weakly electric fish :
(1985)
A series of experiments was performed to investigate various behavioral and neurophysiological aspects of the Novelty Response (NR) of pulse-type weakly electric fish. The NR is a reflexive behavior in which the fish ...
Factors influencing the variance in sign learning performance by four juvenile orangutans (Pongo pygmaeus) /
(The University of Oklahoma., 1985)
Following the methods of Gardner and Gardner 1969 and Fouts 1973 , ten signs (American Sign Language) were trained to four juvenile orangutans. None of the subjects acquired all of the signs even after 2400 trials ...
Genetic and morphologic variation within and among populations of the black-tailed prairie dog.
(1981)
Genetic variation for seven variable loci and morphometric variability for 17 cranial characters were analyzed for black-tailed prairie dogs (Cynomys ludovicianus) within and between populations in eastern New Mexico. ...
A phenetic assessment of the Ciconiidae (Aves) using skeletal morphology.
(1982)
The stability (measured using matrix correlations) of phenetic classifications based on partitions of continuous morphometric data (skeletal measurements from three groups of birds) was compared for analyses involving two ...
The gray bat, Myotis grisescens, in the southwest portion of the Ozark Plateau :
(1980)
To determine the seasonal movements, maternity sites, hibernacula and philopatry of the gray bat, Myotis grisescens, in the southwest portion of the Ozark Plateau, 6858 gray bats were banded at seven locations in Missouri ...
Ecology of Helicopsyche borealis (Hagen) (Trichoptera : helicopsychidae) :
(1984)
The life history and microdistribution of Helicopsyche borealis was compared for a 13-month period in two Oklahoma streams that have different thermal regimes. Densities of H. borealis were usually higher in the thermally ...
Life with and without sex :
(1980)
Nepotistic behavior was never observed among parthenogenetic whiptails for several possible reasons. First, it appears that members of parthenogenetic whiptail populations are not genetically identical due to independent ...
Acute toxicity of hydrogen sulfide to fish during harvesting operations on commercial catfish farms :
(1980)
Unconsumed fish food apparently resulted in the high sulfide concentrations seen near the feeding area in May or June and September of both years. Dissolved sulfide concentrations decreased near the feeding area in July ...
