Phylogeny and zoogeography of glyptocephalines (Pisces: Pleuronectidae)

Creator:: Chiu, Tai-sheng
Abstract:: Hypotheses of phylogenetic and historical zoogeographic relationships of glyptocephalines (Glyptocephalus cynoglossus, G. zachirus, G. stelleri, Microstomus kitt, H. pacificus, H. achne, Embassichthys bathybius, and Tanakius kitaharae) were constructed based on comparative anatomy and external morphology. The phylogenetic approach was cladistic and character polarity was determined by using out-group comparison. One...

Acute and chronic toxicity studies with monochlorobenzene in rainbow trout

Creator:: Dalich, George M.
Abstract:: The toxicity of chlorobenzene (CB) was investigated in rainbow trout following acute ip administration (1. 0 ml/kg, 1:1 in corn oil) and chronic exposure (2. 1 ppm and 2. 9 ppm) via the water in a continuously flowing system for 15 and 30 days. In the acute study, overt toxicity...

Wheat genotypes selected under optimum conditions and their response to water and heat stress

Creator:: Briceno-Felix, Guillermo Ariel
Abstract:: Concerns have been expressed that wheat (Triticum aestivum L.) cultivars selected under optimum conditions may lack adequate adaptation for stress environments. Experimental populations were grown under three environmental conditions 1) optimum, 2) reduced irrigation, and 3) high temperature. Field experiments were conducted at the Center for Northwest Experimental Station (CIANO),...

Fish oral antigen delivery system development and optimization

Creator:: Zhang, Jia Ai (Allen)
Abstract:: Oral administration is the most practical way of vaccination of fish. It has advantages over intraperitoneal injection and immersion methods that include no stressful handling, no interference with routine fish husbandry and antigens can be delivered to the fish in their feed. An oral antigen delivery system was developed for...

Interactions between the immune system, stress and thymulin

Creator:: Christian, Richard L., (Richard Leroy), 1971-
Abstract:: This study was conducted to determine the effects of shipping stress on the immune system in domestic lambs (Ovis aries) and to determine the potential of the thymic peptide, thymulin, to reduce those effects of stress on the immune system. Treatments consisted of no shipping (as unstressed controls), shipping (as...

Effects of harvest date on sweet corn maturity, sugar content and yield

Creator:: Wong, Yueh-Mei
Abstract:: Studies were conducted in 1976 and 1977 on the effects of harvest dates on maturity, yields and sugar content of four cultivars of sweet corn. The cultivars were 'Golden Cross Bantam', 'Jubilee', 'Rapidpak' and 'Tendertreat'. Moisture content of kernels ranged from 80 to 67 per cent for the six harvest...

Determination of α-Amylase activity and soluble starch content in normal and cork spotted D̀'Anjou' pear fruit

Creator:: Li, Shiao Jing
Abstract:: There was a linear relationship of [alpha]-amylase activity from 2 to 12 hours incubation in both freeze-dried and fresh 'd'Anjou' pear fruit tissue. Activity was greater, however, in fresh as compared with freeze-dried tissues. [alpha]-Amylase activity from both types of samples was not detected until 60 minutes incubation. After 90...
