Species With Extrafloral Nectaries In A Temperate Flora (Nebraska), Kathleen H. Keeler Mar 1979

Species With Extrafloral Nectaries In A Temperate Flora (Nebraska), Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

Extrafloral nectaries (EFNs) are glands on a plant, not involved in pollination, that produce solutions containing sugars (and other compounds). Long noted by morphologists, EFNs have recently been observed to be part of ant-plant mutualisms. The function of EFNs appears to be to attract aggressive insects, especially ants, which by disturbing or preying upon herbivores, reduce damage to the plant (Janzen, 1966a,b; Elias and Gelband, 1975; Keeler, 1975, 1977; Bentley, 1976, 1977a,b; Schemske, 1978; Tilman, 1978; Inouye and Taylor, 1979; Pickett ad Clark, 1979). Furthermore, they constitute an unusual plant defense against herbivores: at EFNs plants employ ants as a …


Nocturnal Pollination Of Abronia Fragrans (Nyctaginaceae), Kathleen H. Keeler, Myra S. Fredricks Jan 1979

Nocturnal Pollination Of Abronia Fragrans (Nyctaginaceae), Kathleen H. Keeler, Myra S. Fredricks

School of Biological Sciences: Faculty Publications

Abronia fragrans Nutt. (Nyctaginaceae) is a white-flowered herb of dry sandy soils from Idaho and South Dakota to Arizona and Texas. It can be readily observed to fit a night-blooming, moth-pollinated syndrome (Faegri and van der Pijl, The principle of pollination ecology, 1971). This does not seem to have been noted: in all references to A. fragrans we could find, the only indication of nocturnal anthesis was the comment of Nelson (Handbook of Rocky Mountain plants, 1969), who observed that the fragrance was more noticeable at night. Tillett (Brittonia 19:299-327, 1967), working on Pacific species, suggested that the …

The Extrafloral Nectaries Of Ipomoea Carnea (Convolvulaceae), Kathleen H. Keeler Nov 1977

The Extrafloral Nectaries Of Ipomoea Carnea (Convolvulaceae), Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

lpomoea carnea (Convolvulaceae) possesses two types of extrafloral nectaries, located on the petiole and on the pedicel. These secrete a complex nectar containing sugars and amino acids. The insects attracted to the extrafloral nectaries are predominantly ants and they are relatively abundant throughout the year. A number of incidents of plant defense as a result of the presence of extrafloral nectary visitors at the extrafloral nectaries of I. carnea were observed and are consistent with the ant-guard theory of the function of extrafloral nectaries.

A Bibliography Of Taxonomic Literature Of The Great Plains Flora, With Supplements I, Ii, And Iii, Ralph E. Brooks Dec 1976

A Bibliography Of Taxonomic Literature Of The Great Plains Flora, With Supplements I, Ii, And Iii, Ralph E. Brooks

School of Biological Sciences: Faculty Publications

There is at present no recent comprehensive manual of the Great Plains flora. Consequently, students of the flora must utilize monographs, revisions, and other sources in their work. This bibliography was compiled in order to facilitate location of available literature, and will be useful to anyone interested in the systematics of the plants of the Great Plains. This compilation was produced for the Great Plains Flora Association as an initial step in the preparation of a major flora for the region.

Mosses Of The Great Plains: Introduction And Catalogue, Steven P. Churchill

School of Biological Sciences: Faculty Publications

This account initiates a series of articles concerning the mosses of the Great Plains. The boundary of this region (Fig. 1) is adopted in part from a parallel study currently in progress on vascular plants (McGregor et aI., 1977). However, in addition, this moss study includes that region of Canada studied by Bird (1962). The total area included in this study of the Great Plains thus occupies about 665 thousand square miles, extending from southern Manitoba to southeastern Alberta, south to northeastern New Mexico and northwestern Oklahoma.

Crum, Steere and Anderson (1973) have listed 1,170 species, 267 genera, and 58 …

New Records Of Native And Introduced Plants From Nebraska, Steven P. Churchill, Robert B. Kaul, David M. Sutherland Jan 1976

New Records Of Native And Introduced Plants From Nebraska, Steven P. Churchill, Robert B. Kaul, David M. Sutherland

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Recent field work in Nebraska by staff of the University of Nebraska Herbarium has produced a number of records of previously uncollected specimens and has confirmed the presence of species collected only a few times long ago. Some of the records are of American species which are indigenous to Nebraska or which have recently spread to the state, while other records are of foreign species which are thoroughly established in the wild. Some of these are potentially serious weeds, though none have reached that stage yet.

All specimens cited are deposited in the University Herbarium in Nebraska Hall, Lincoln, except …


Anatomical Observations On Floating Leaves, Robert B. Kaul Jan 1976

Anatomical Observations On Floating Leaves, Robert B. Kaul

School of Biological Sciences: Faculty Publications

An examination of 24 genera of aquatic plants having floating leaves and leaf-like thalli has been made. Functional stomata occur on the adaxial sides of floating leaves of angiosperms and some ferns, and in some floating leaves there are stomata on the abaxial surface as well. Most floating leaves have prominently chambered mesophyll, and in some instances the chambers are locally enlarged and form buoys.

School of Biological Sciences: Faculty Publications

This is the first report of Ipomoea carnea (Convolvulaceae) from lowland Costa Rica. These populations are unusual for the species in flower color, flowering season and pollinator. Other aspects of the biology of the species in Guanacaste, especially pollination, flower robbing and extrafloral nectary visitors, are discussed.

Lysimetric Calibration Of The Bowen Ratio-Energy Balance Method For Evapotranspiration Estimation In The Central Great Plains, Blaine L. Blad, Norman J. Rosenberg Mar 1974

Lysimetric Calibration Of The Bowen Ratio-Energy Balance Method For Evapotranspiration Estimation In The Central Great Plains, Blaine L. Blad, Norman J. Rosenberg

Department of Agronomy and Horticulture: Faculty Publications

Most reports show good agreement between evapotranspiration (ET) rates estimated by Bowen Ratio-Energy Balance (BREB) method and rates measured with lysimeters, although underestimation by the BREB model has occasionally been reported. This study was conducted to evaluate the performance of the BREB technique in the climatic conditions characteristic of the central Great Plains, a region where a significant proportion of the energy consumed by evapotranspiration is supplied from advected sensible heat.

Agreement between the BREB method and lysimetric measurements of ET is good during non-advective periods but during advective periods the BREB model underestimates ET by about 20%. Data collected …
