The fruits and seeds of the Rancho La Brea Pleistocene deposits

Creator:: Templeton, Bonnie Carolyn
Abstract:: More than 4,000 specimens of fruits and seeds were extracted from the matrix removed from inside the skulls of sabre-tooth cats excavated from various pits in the Rancho La Brea deposits. Of this number, spproximately 1,445 specimens are involved in this study. Many comparisons with modern fruits and seeds made...

Seasonal pattern of secondary growth in stems of northern white spruce (Picea glauca (Moench) Voss)

Creator:: Gregory, Robert A.
Abstract:: Cambial activity in white spruce stems in Alaska was observed from April, 1964 to September, 1965 in over 300 samples taken from 50- to 60-year-old natural stands. Mitotic index was used as a measure of the rate of periclinal division of fusiform cells in the cambial zone. Anticlinal divisions are...

Anatomical studies of Pinus ponderosa Laws : infested by Elytroderma deformans (Weir) Darker

Creator:: Wirtz, Felicia Pietrykowski
Abstract:: Pine needle blight of Pinus ponderosa Laws. caused by Elytroderma deformans (Weir) Darker is recognized by changes in the needles, in the bark and in the development of the branches. Anatomical studies of the host-parasite relation have been made previously on young pine tissue up to four years of age...

Anatomical changes in the secondary phloem of grand fir (Abies grandis (Dougl.) Lindl.), induced by the balsam woolly aphid (Adelges piceae Ratz.)

Creator:: Saigo, Roy Hirofumi
Abstract:: The balsam woolly aphid (Adelges piceae Ratz.) feeds by inserting its stylets intra- and intercellularly into the cortex or outer phloem of the true firs. While feeding, the aphid injects into the bark an unknown stimulatory substance which affects the adjacent cortical parenchyma cells, the activity of the vascular cambium...

The culture and biochemical analysis of some estuarine phytoplankton species

Creator:: DeMort, Carole Lyle
Abstract:: The biochemical composition of ten species of estuarine phytoplankton was determined. Studies were made of their growth in various culture media and of their relative value as food for oyster larvae. Nine of the species were isolated from Yaquina Bay, Oregon. An attempt was made to select species which commonly...

Benthic algal communities of the Metolius River

Creator:: Sherman, Barbara Jane Powell, 1938-
Abstract:: Samples of benthic algae were collected from the Metolius River of central Oregon at two-week intervals between April 15, 1967 and March 9, 1968. Species of filamentous algae and diatoms present were recorded for every sampling station on each sampling date. Permanent mounts of diatom frustules were prepared. This sampling...

Development of the storage organ of Brassica campestris L.

Creator:: Larson, Ann Marie
Abstract:: Developmental changes in the storage organ of Brassica campestris L. were followed from the organization of the embryonic radicle and hypocotyl to the mature storage organ. Three independent primary meristems gave rise to the cortex, the stele, and the root cap-epidermis. The primary development is typical of the Cruciferae. Cambial...

Root initiation and differentiation in Pseudotsuga menziesii (Mirbel) Franco

Creator:: Bogar, Gerald Dale
Abstract:: Tissue differentiation of the primary root and its associated laterals is reported. Secretory elements are the first of the primary tissues to mature. They appear to be located between the precursory phloem and pericycle in the primary root, but are more closely associated with the pericycle in long lateral roots....

Comparative wood anatomy of the Fagaceae of Taiwan

Creator:: Lee, Chun-shu
Abstract:: Many species of the Fagaceae have been variously interpreted on the basis, primarily of external morphological characteristics. The objectives of this study are to elucidate generic and specific characteristics of the wood of Fagaceae and to attempt to obtain evidence regarding taxonomic relationships among some of the species occurring in...
