Por sua vez, as sinúsias de trepadeiras respondem às mudanças temporais ecológicas e ambientais decorrentes das alterações na estrutura das florestas. Nas florestas tropicais em sucessão secundária, os processos ecológicos responsáveis pela organização das sinúsias de trepadeiras estão relacionados às mudanças que ocorrem na estrutura arbórea ao longo do tempo, uma vez que as trepadeiras estão associadas fisicamente às árvores. Meu objetivo foi investigar os processos e padrões relacionados com a organização e a estrutura de comunidades de trepadeiras em diferentes estádios sucessionais, e relacioná-los com a disponibilidade de recursos limitantes, como suportes e luz, em escala local e regional. Para tanto, utilizei uma cronossequência formada por quatro florestas, sendo três restauradas em tempos diferentes e um remanescente com floresta natural madura. No capítulo 1, quantifiquei alguns parâmetros ecológicos das sinúsias de trepadeiras entre as florestas e encontrei diferenças significativas. No capítulo 2, pude demonstrar como que a organização filogenética de cada comunidade em cada fragmento florestal, i.e. em escala local, foi relacionada à variação na disponibilidade de recursos. No capítulo 3 discuti como a variação de luz entre os fragmentos florestais, i.e. em escala regional, influenciaria a organização filogenética e funcional das comunidades de trepadeiras / Abstract: Climbing plants occupy a prominent place in many tropical forests not only as a constituent element, but also as a group of species that is able to lead the organization of forest communities over time. In turn, the climbing plants of synusiae respond to ecological and environmental changes resulting from alterations in the temporal structure of forests. During secondary succession of tropical forests, the ecological processes responsible for the organization of communities of climbing plants are related to changes in the tree structure over time, since climbing plants are physically attached to the trees. My goal was to investigate, in local and regional scale, the processes and patterns related to the organization and structure of communities of climbing plants in different successional stages, and relate them to the availability of limiting resources, such as light and supports. For this, I used a chronosequence comprised of four forests, three forests restored at different times and a remnant mature natural forest. In Chapter 1, I computed some ecological parameters about climbing plants communities and compared between the forests. In Chapter 2, I demonstrated how the phylogenetic organization of each community in each forestal fragment, i.e. on a local scale, was related to changes in resource availability. In Chapter 3, I discussed how the light variation between forestal fragments, i.e. at the regional scale, would influence the phylogenetic and functional organization of communities of climbing plants / Doutorado / Biologia Vegetal / Doutor em Biologia Vegetal

Polyfunkční objekt / Multifunctional building

Lauko, Marek January 2020 (has links)
The aim of the diploma thesis is to prepare documentation for construction. The building is partially basement and in terms of building physics is designed as a building with almost zero energy consumption. For the purpose of the work is chosen multifunctional object, which consists of veterinary clinic and shop with pet supplies. The building land is located in the cadastral area of Brno-Královo Pole in a built-up area designated for mixed areas of trade and services on a relatively flat plot no. 4800/28 on Edisonova Street. The new building is located on the southeast side of the property, which is followed by parking from the northwest side. The purpose, appearance and volume of the building do not interfere in any way with the character of the territory. Veterinary clinic is partially basement with two floors. In the basement is a technical background for the whole multifunctional building. On the first floor is a waiting room with a reception and two examination rooms, an office and a changing room for employees. On the floor are specialized workplaces, X-ray, ultrasonographic, otoscopic, laboratory and operating room together with hospitalization for animals. The shop with pet supplies is designed as a single storey, consisting of a sale area with a warehouse and facilities for employees. The southeast facade is covered with expanded metal. The construction system of the building is wall-mounted, made of ceramic bricks for thin-layer mortar. Ceiling constructions are designed from large-area filigree panels. The roof is vegetational.
