Zobrazení krajiny od 17. století do počátku 20. stoletíKLOMFAROVÁ, Monika January 2016 (has links)
The thesis is focused on the development and presentation of landscape painting from the 17th century to the early 20th century. The work is divided into a theoretical and practical. The theoretical part is focused on Dutch, Italian, English, French and foremost Czech landscapes, its main leaders and contemporary Czech artist Frantisek Hodonsky presenting the landscape in abstract form. It explores the influence of the Impressionist style, which inspired the practical part of the thesis. The practical part includes a summary of sketches which rendition of meadow in various forms also with different impressions of the momental feeling from the landscape. The practical part explains the preparation of the canvas and the subsequent production of three paintings measuring at least of 50 x 80 cm.

Odor preference and social behavior in meadow voles, Microtus pennsylvanicusFerkin, Michael H. January 1989 (has links)
Thesis (Ph.D.)--Boston University / PLEASE NOTE: Boston University Libraries did not receive an Authorization To Manage form for this thesis or dissertation. It is therefore not openly accessible, though it may be available by request. If you are the author or principal advisor of this work and would like to request open access for it, please contact us at open-help@bu.edu. Thank you. / Seasonal differences in odor preference and social behavior existed among adult meadow voles. During the breeding season, a female preferred its own odor and the odor of males to the odor of another females. Males preferred the odor of females to the odor of other males. Paired encounters between breeding females were more agonistic than encounters between males or encounters between males and females. During the nonbreeding season, a female preferred the the odor of another female to the odor of males. Males did not display an odor preference for any conspecifics. Paired encounters between males were more agonistic than encounters between males and females or encounters between females. Encounters between nonbreeding females contained few agonistic acts. Seasonal differences also existed in the interactions between adults and juveniles. During the early breeding season, adult males were more agonistic than adult females toward juvenile males. During the late breeding season, adult females were more agonistic than adult males toward juvenile males. Encounters between an adult female and a juvenile female in the late breeding season contained few agonistic acts, indicating that overwintering groups are female-biased, and contain juvenile females. Juveniles did not display a shift in odor preferences. They preferred the odor of opposite-sex adults to the odor of same-sex adults, regardless of season. Familiarity, through association during rearing, reduced agonistic behavior between parents and young, and between siblings. Paired encounters between close-kin that were not familiar were agonistic, and similar to encounters between unfamiliar, and unrelated conspecifics. Conspecifics were more agonistic toward closely related males than females. Voles also preferred the odor of a familiar nestmate, independently of genetic relatedness. Familiarity decreased the number of agonistic behaviors between adult females, but increased the number of agonistic behaviors between adult males. Familiarity had no effect on the number of agonistic behaviors between a male and a female. / 2031-01-01

Adaptive Reuse and Renovation: A Learning Center, Huntley Meadows Park And The Huntley VillaLucente, Richard C. 12 October 2000 (has links)
In doing research for the documentation of the Huntley Meadows Plantation for public record at the Library of Congress and assessing a possible use for this site for the Friends of Huntley, i saw a humble little piece of Virginian history decaying and being swept away by sprawling development. Sufficient research of historical American architecture is important to determine whether it has cultural or architectural significance.
This thesis does not provide a solution to this problem of preserving architecture. It is a case study for preserving and reactivating Huntley Meadows Plantation and Huntley Meadows Park through adaptive reuse and renovation. / Master of Architecture

Conservation and ecological restoration of Rocky Mountain subalpine meadows: vegetation responses to tree encroachmentShaw, Adrienne Kara 20 April 2009 (has links)
Over the past century tree encroachment has occurred in North American subalpine meadows. Causes of tree establishment have been related to climate influences and exclusion of fire, but very few studies have looked at the consequence of tree encroachment on meadow vegetation. Within the southern Canadian Rocky Mountains, Waterton Lakes National Park and Castle Special Management Area,
14 meadows were randomly selected at wet and dry sites. Nonmetric multidimensional scaling showed that species composition changed during the transition of open meadow to forest for both wet and dry habitats. There were no significant differences in these two management areas in terms of conifer encroachment and the effects on meadow species. Results of this study show that conifer encroachment has increased over the last century with the consequences of loss in meadow species through a decrease in abundance, richness and diversity. Wet sites were significantly more sensitive to conifer encroachment than dry sites. The greatest
inhibitory effects of trees on meadow vegetation within the ecotone occurred when trees were 54-72 years old for wet sites and 77-112 years old for dry sites. Ecological restoration of these meadows is important for ongoing habitat conservation, maintaining species and landscape diversity and ecosystem resilience.

Vegetative ecology of Hunts Cove, Mt. Jefferson, OregonCampbell, Alcetta Gilbert 22 February 1973 (has links)
The vegetative communities in the subalpine meadows of Hunts
Cove, Mt. Jefferson, and some of the major environmental factors
affecting them were studied in the summer of 1971. Hunts Cove is in
the subalpine Tsuga mertensiana parkland of the Central Oregon High
Cascades. Habitats within the Cove vary considerably; elevation
changes from 1500 m to 1900 m; water regime ranges from bogs and
seeps to desert; snowlie varies as much as two months at different
points in the same year.
Estimates of vegetative cover and frequency were taken on 300
quadrats. Snow lie was monitored on a weekly basis. Soils were collected
and analyzed.
Eleven meadow communities were distinguished. They are:
A. The short sedge communities, 1) Carex nigricans-Aster and
2) Carex nigricans-Polytrichum on late snowfree, poorly drained sites;
B. Bryophyte, on very late snowfree, damp, shaded soil; C. Heath
communities on well drained sites, 1) Phyllodoce-Cassiope on
exposed late snowfree slopes, 2) Vaccinium deliciosum on moderately
late snowfree slopes and 3) Potentilla-Carex nigricans on very
late snowfree sites with rodent activity; D. Senecio lush herb on mesic
warm sites; E. Hydric communities, 1) Eleocharis-Aulacomnium
occurring in stagnant water, 2) Carex rostrata-Sphagnum in freely
moving water, 3) Carex scopulorum in seeps and bogs with permanent
water supply, probably an edaphic climax, and 4) Carex sitchensis in
swamps flooded during meltoff.
These communities were arrayed in a floristic ordination and the
position of all hydric, lush herb, and short sedge sample plots was
found to parallel snowfree dates. Well drained heath communities
became snowfree in the order expected from other studies.
Comparison of the communities with other studies from the
Northwest suggests Phyllodoce-Cassiope, Vaccinium deliciosum and
the Carex nigricans communities to be parts of a consistent vegetative
pattern extending north into Southern B. C. / Graduation date: 1973
