Working to the conservation and good use of the Devonian palaeontological heritage in Floresta, Boyacá (Colombia): a review of teaching case studies …
2019
The Floresta Massif, located in the Eastern Cordillera of Colombia, has a diverse and precious natural heritage. It is one of the areas that contains an exceptional palaeontological heritage of the Middle Devonian not only of Colombia, but also of South America. This heritage is represented by fossil specimens of marine fauna and terrestrial flora (correlated with North America and Europe) of the Floresta and Cuche Formations, respectively. Since 2004, actions made by several academic and research institutions, community and local government have introduced schoolchildren, teenagers and University students to art and science, and have promoted the conservation of palaeontological heritage a…
Indikatori piekrastes lagūnu biotopu struktūras un funkciju novērtēšanai
2015
Indikatori piekrastes lagūnu biotopu struktūras un funkciju novērtēšanai Laura Ločmele. 2015. Piejūras mitrāju biotopu kompleksi Latvijā ir reti sastopami.Šī iemesla dēļ veikts pētījums ar mērķi novērtēt piejūras lagūnu stāvokli un noskaidrot to kvalitāti raksturojošos indikatorus. Lauka apstākļos tika ievākti dati par ūdens ķīmiskajiem parametriem, lagūnu floru un veģetāciju. Ar attālās izpētes palīdzību, iegūti dati par veģetācijas struktūru un lagūnu ģeogrāfiskajiem parametriem. Galvenās darbā izmanotās datu apstrādes metodes bija PCA, TWINSPAN un korelācijas analīze. Tika veikta lagūnu kvalitātes novērtēšana, balstoties uz to struktūras un funkciju indikatoriem. Pētījumā tika secināts, …
Gardens on Canvas and Paper: Cataloguing Botanical Abundance in Late Medici Tuscany
2016
What is the purpose of portraying a branch from a pear tree in bloom and fruit, of listing hundreds of citrus varieties or of dissecting a huge truffle? When Cosimo III (1642–1723), the penultimate grand duke of the Medici dynasty, commissioned artists and botanists alike to create comprehensive visual and textual catalogues of Tuscan flora, aesthetics and curiosity seemed to go hand in hand with a demonstration of knowledge and prosperity. This article deals with the collection of botanical paintings by Bartolomeo Bimbi (1648–1730), housed in the Casino della Topaia close to the city of Florence, and with the mainly handwritten work of the grand ducal botanist Pier Antonio Micheli (1679–17…
Floristic survey of the former royal hunting reserve of Renda, near Palermo (Sicily, Italy)
2021
A mountainous area in western Sicily, where relic wood vegetation is still preserved notwithstanding past and present human pressure, is here analysed in order to prepare a checklist of its vascular flora. Field investigations allowed to compile a floristic inventory including 601 infrageneric taxa belonging to 304 genera and 80 families. Some remarks on the biological and chorological spectra are presented, and some measures to protect flora and vegetation are suggested, too.
POLLEN MORPHOLOGY AND REPRODUCTIVE PERFORMANCES IN OPUNTIA FICUS-INDICA (L.) MILL.
2015
The fruits of Opuntia ficus-indica (L.) Mill., the most worldwide cultivated species of Cactaceae family, contain viable seeds (100-250) of large size. This characteristic influences the commercial quality of the fruit. The study of floral biology in Opuntia allows to understand the behaviour of the plant during reproductive phase and perhaps to distinguish clones with different fruits behaviour (with seed and seedless). The study resulted in a palynological characterization by optical and scanning microscopy (SEM), followed by a qualitative analysis on the male line with pollen viability and in vitro germination tests, in addition to a pollen-pistil interaction survey. The plant material c…
