Descriptive Ethology And Activity Patterns Of Black-Footed Ferrets, Tim W. Clark, Louise Richardson, Steven C. Forrest, Denise E. Casey, Thomas M. Campbell Iii

Great Basin Naturalist Memoirs

Aspects of the aboveground ethology and activity patterns of the black-footed ferrets (Mustela nigipes) are described for a population in northwestern Wyoming as a first step in building a descriptive ethogram and quantification of activity patterns. We observed at least 237 individual ferrets for 208 hr on 441 occasions from 2 December 1981 through 25 September 1984. Mainenance behaviors (locomotion, alert, grooming, and sunning, defecation and urination, digging, and predation) and social behavior (reproduction, ontogeny, maternal, play, agonistic) are described as well as some ferret-human interactions. Ferret vocalizations are subjectively described. We located ferrets during most months including …

Description And History Of The Meeteetse Black-Footed Ferret Environment, Tim W. Clark, Steven C. Forrest, Louise Richardson, Denise E. Casey, Thomas M. Campbell Iii

Great Basin Naturalist Memoirs

The black-footed ferret (Mustela nigripes) occupied area lies in the western Big Horn Basin, Park County, Wyoming. Cody, a nearby town, shows a record high temperature of 40.5 C and a low of -43.3 C, with 173 days each year below 0 C. Area geology is dominated by Absaroka volcanics. Soils are shallow (0.5 m) and underlain by unconsolidated gravels; well-drained, medium-textured clay-loams (ca 1 m in depth); or clays derived from shale parent materials. Vegetation is characterized by a wheatgrass-needlegrass shrubsteppe type (Agropyron/Stipa/Artemisia). Prior to white settlement, the area hosted a diverse large mammal community. …

Organic Matter Budgets And Models For Four Plant Communities In The Great Dismal Swamp, J. Patrick Megonigal

Biological Sciences Theses & Dissertations

Budgets and models of organic matter dynamics were developed for one mesic and three seasonally flooded plant communities in the Dismal Swamp. Components included aboveground parts, belowground parts, litter and soil organic matter (SOM).

Net primary- production was significantly greater on them flooded sites. Comparisons show that the Dismal Swamp is highly productive despite relatively low nutrient inputs.

Budget calculations showed that over 65% of the total input to SOM comes from roots. Leaves contributed about 70% of the aboveground inputs.

The model predicted that species composition, aboveground biomass and turnover rates on the cedar site will become quite similar …

Laboulbeniales On Semiaquatic Hemiptera. V. Triceromyces, Richard K. Benjamin

Aliso: A Journal of Systematic and Floristic Botany

Six species of Triceromyces (Laboulbeniales), including the type, T. balazucii (on Hebridae), parasitic on semiaquatic Hemiptera, were studied at the light-microscopic level. Descriptions are provided for all of the taxa, and features of developmental morphology are described, compared, and illustrated with photographs and line drawings. Four species are described as new: T. hebri (on Hebridae), T. hydrometrae (on Hydrometridae), and T. biformis and T. bullatus (on Mesoveliidae). The species growing on Hebridae and Hydrometridae are monoecious. The two species on Mesoveliidae develop monoecious and dioecious morphs, which occur together on the same host individual. This phenomenon is recognized and described …

Wood Anatomy Of Stilbaceae And Retziaceae: Ecological And Systematic Implications, Sherwin Carlquist

Aliso: A Journal of Systematic and Floristic Botany

Wood anatomy of ten species in five genera of the Cape Province (South Africa) family Stilbaceae is reported in quantitative and qualitative terms. Wood anatomy for stem, root, and lignotuber is reported for the monotypic Cape genus Retzia. Stilbaceae and Retziaceae are alike in wood anatomy but differ from Verbenaceae by having scalariform perforation plates with few and wide-bordered bars (simple plates and modified scalariform plates are also present); vessel elements clearly fibriform in shape; very scarce axial parenchyma; and long uniseriate wings on multiseriate rays. When added to endosperm presence and ericoid habit, these features may serve to segregate …

The Distribution And Phytogeographic Relationships Of The Woody Plants Of The Soviet Far East, Thomas S. Elias

Aliso: A Journal of Systematic and Floristic Botany

The woody flora of the Soviet Far East is rich and diverse when compared to dendrofloras at similar latitudes of the world. The bulk of this region lies north of latitude 46 degrees. This area includes the northernmost stations in eastern Asia for many genera, e.g., Abelia, Acer, Aralia, Carpinus, Corylus, Fraxinus, Hydrangea, Ilex, Juglans, Magnolia, Morus, Quercus, Phellodendron, Sasa, Schizophragrna, Schisandra, Skimmia, Syringa, Tilia, and Ulmus. The majority of the woody species native to the Soviet Far East do not occur elsewhere in the U.S.S.R. Many of the trees and shrubs are native to Japan, Korea, or China and …

On The Submersion Of Dicraurus Into Iresine (Amaranthaceae), James Henrickson, Scott Sundberg

Aliso: A Journal of Systematic and Floristic Botany

The two species of Dicraurus Hook. f. (Amaranthaceae) are shown to be more closely related to different species in Iresine L. than they are to one another. In addition, characters used to distinguish Dicraurus are more widespread within Iresine than was formerly thought, necessitating the merger of Dicraurus into Iresine. The two species as placed in Iresine are I. alternifolia S. Wats. and I. leptociada (Hook. f.) Henrickson & Sundberg. Complete descriptions and distribution maps of the two species are included.

Reproductive Phytochemistry Of Bombacaceae, Ron Scogin

Aliso: A Journal of Systematic and Floristic Botany

Floral anthocyanins among Bombacaceae exhibit minimal variation and consist of three commonly occurring cyanidin glycosides. Cyanidin 3-rutinoside occurs uniquely in the genus Pachira among taxa surveyed. Nectars are characterized by copious volumes and being somewhat dilute and hexose rich with respect to sugars. No evidence is detectable among Bombacaceae for a nonfiying-mammal floral chemistry syndrome which is distinguishable from a bat-visitation syndrome.

Floral Pigments Of The Yellow Camellia, Camellia Chrysantha (Theaceae), Ron Scogin

Aliso: A Journal of Systematic and Floristic Botany

Floral pigments of Camellia chrysantha consist of three flavonoids (quercimeritrin, rutin, and isoquercitrin) and two xanthophylls (neoxanthin and an unidentified xanthophyll). The transfer of yellow petal coloration from C. chrysantha to other Camellia species may be hampered by interspecific genetic incompatibilities and by the complexities of genetic regulation of biosynthesis of the pigments involved.

Wood Anatomy Of Cassiope (Ericaceae), Gary D. Wallace

Aliso: A Journal of Systematic and Floristic Botany

Wood anatomical characteristics for 21 taxa of Cassiope are reported. Qualitative features differ somewhat from the general pattern of the Ericaceae. However, considerable deviation is found in the quantitative aspects of the wood features. The stems are very slender with narrow growth rings evident in all but one species. Vessel elements are very small and usually have scalariform perforation plates with several bars. Vessels are extremely abundant in transection. Vascular rays are mostly uniseriate with a few biseriates and all are composed exclusively of erect cells. The imperforate elements are tracheids which are the only conductive elements in the late …

Wood Anatomy Of Gesneriaceae, Sherwin Carlquist, David A. Hoekman

Aliso: A Journal of Systematic and Floristic Botany

Qualitative and quantitative data are presented for woods of 37 species representing 11 genera; most species included represent a maximal degree of woodiness for the family, and herbaceous groups are mostly omitted. Growth rings are absent or nearly so. Vessel elements have simple perforation plates (except for Kohleria elegans) and alternate circular or oval pits of various sizes on vessel-vessel walls (often laterally elongate, often with gaping apertures, on vessel-parenchyma and vessel-septate fiber interfaces). Grooves interconnect pit apertures in vessels of four genera. Vessels are grouped, usually in radial chains, to a moderate extent. Tyloses are present. Imperforate tracheary …

An Understory Survey Of Baber Woods, Edgar County, Illinois, Amy Jo Burns

Masters Theses

Several vegetation studies have been undertaken in Baber Woods, Edgar County, Illinois, in the past 20 years. After looking at the data of these studies it was decided that an additional study was needed to determine if the increasing importance value (IV) of Acer saccharum was indeed important. It appears that this species is starting to take over the native oak-hickory woods as well as decreasing the diversity of the herbaceous understory (Ebinger, 1986). The present study was undertaken to determine of Acer saccharum has increased enough to justify implementation of some type of forest management.

Wood Anatomy Of Myoporaceae: Ecological And Systematic Considerations, Sherwin Carlquist, David A. Hoekman

Aliso: A Journal of Systematic and Floristic Botany

Quantitative and qualitative features are presented for 28 collections of three genera (Bontia, Eremophila, Myoporum); data on Oftia are also included since it is sometimes referred to Myoporaceae. Wood of all Myoporaceae represents variation on a basic plan: woods diffuse porous or semi-ringporous; vessels with simple perforation plates; lateral wall pits of vessels alternate and circular, with grooves interconnecting some pit apertures; vessels grouped to various degrees into radial multiples; imperforate tracheary elements all fiber-tracheids with pit cavities 1-5 μm in diameter (wider on contacts with ray cells), nonseptate; axial parenchyma vasicentric scanty plus, in some …

Systematic And Ecological Wood Anatomy Of Californian Scrophulariaceae. Ii. Penstemon Subgenus Saccanthera, David C. Michener

Aliso: A Journal of Systematic and Floristic Botany

Wood anatomy of nonarboreal Scrophulariaceae is little studied, yet such information is needed to understand the evolution of woodiness in the family and order. Description and quantification of wood characters of six species (nine taxa) of Penstemon subgenus Saccanthera show that these woods are specialized. Paedomorphic features include the standard declining-to-level curve of vessel element length by age, and (in several samples) a pronounced tendency to raylessness. Variation in ray characteristics is as great within as between species, suggesting that unsampled populational variation in ray characteristics may be present. Cells intermediate between fibers and nonseptate parenchyma are present and complement …
