The theoretical part contains summary of the literature on the topic of succession, mining, human impacts on biodiversity, land reclamation and ecological requirements of reptiles and amphibians. The practical part contains the observations of these two model groups of animals and subsequent evaluation of their abundance and diversity. During the three years I made total 37 herpetological observation, during which I observed the occurrence of eight species of reptiles and amphibians on five locations. When observing reptiles and amphibians I used non-invasive methods of observation. The found species were Zootoca vivipara (507 individuals), Lacerta agilis (583 individuals), Pelophylax esculentus (976 individuals), Pelophylax ridibundus (710 individuals), Pelophylax lessonae (1,401 individuals), Lissotriton vulgaris (203 individuals), Natrix natrix (32 individuals) and Anguis fragilis (7 individuals). The values in the brackets represent the total number of individuals found during 3 seasons. Generically the richest site was "Jezírka" (8 species), species habitat poorest contrary, "Přesyp" (2 species). In all the years the abundance of two model groups (frogs and lizards) were significantly different (abundance of Pelophylax: Chí Square = 2764; d. f. = 4, p <0.001, Zootoca + Lacerta: Chí Square = 119; d. f. = 4, p <0.001. Pelophylax: Chí Square = 1573; d. f. = 4, p <0.001, Zootoca + Lacerta: Chí Square = 43; d. f. = 4, p <0.001. Pelophylax: Chí Square = 37; d. f. = 4, p <0.001, Zootoca + Lacerta: Chí Square = 741; d. f. = 4; p <0.001). The researchl lasted three vegetation seasons. They had distinctly different climatic conditions. The abundance of reptiles and amphibians in season of 2013 was significantly impacted by the spring floods. Season 2014 any major climatic fluctuations and therefore I considered it as a standard. Season 2015 was greatly influenced by the high summer temperatures and the lack of greater precipitation during the summer months. This fact influenced mainly amphibian populations.

Vegetation sampling was carried out to determine processes of succession of aquatic and wetland plant species. Different stages of wetland and aquatic vegetation were analyzed in sand pits in the Třeboňsko Protected Landscape Area in the Czech Republic. Moreover different sizes of phytosociologial relevés of aquatic vegetation were analyzed to determine sufficient size for detection of successional changes.

今日、遊具「砂場」は、不十分な認識や過小評価、誤解等により、環境の悪化やその放置、不適切な使用、さらには砂場設置率の大きな低下という問題を抱えている。本研究ではこのような現状を、単なる一遊具の問題ではなく、近代的な子ども観・遊び観の喪失につながる問題として捉え、砂場の物理的環境改善や新たな砂場のデザイン、様々な活用法や価値を伝える知的連携の実験的検証を通し、砂場の価値の再構築を試みた。 / Today, sandboxes are facing problems such as deterioration of the environment, neglect and inappropriate use due to insufficient recognition, underestimation and misunderstanding, as well as a significant decline in the percentage of sandboxes installed. In this study, we have attempted to reconstruct the value of sandboxes by improving the physical environment of sandboxes, designing new sandboxes, and experimentally verifying various uses and intellectual collaboration to convey the value of sandboxes. / 博士(ソーシャル・イノベーション) / Doctor of Philosophy in Social Innovation / 同志社大学 / Doshisha University
