Ruggero Tomaselli
Ruggero Tomaselli (Trento, 22 August 1920 – Monzuno, 30 March 1982) was an Italian botanist. He introduced the study of phytosociology to Italy. Biography Tomaselli was born in Trento on 22 August 1920. In 1943 he graduated from the University of Pavia in Natural Sciences and began his university career as an assistant to the chair of Geology; in 1947 he was appointed assistant of the chair of Botany held by Raffaele Ciferri. In 1946 he specialized in plant cytology at Sorbonne University and in 1948 he began working at the , under the direction of Josias Braun-Blanquet, dedicating himself to the study of phytosociology. After winning a scholarship at the University of Kansas, where in 1952 he worked with the geographer A. W. Kuchler, he returned to Pavia and began to study the phytogeography of Mediterranean vegetation.

University Of Catania
The University of Catania () is a university located in Catania, Sicily. Founded in 1434, it is the oldest university in Sicily, the 13th oldest in Italy, and the 29th oldest in the world. With over 38,000 enrolled students, it is the largest university in Sicily. History The university was founded by King Alfonso I of Sicily on 19 October 1434. A charter was granted after two royal councillors ( Adamo Asmundo and Battista Platamone) convinced the king to accept the founding of a '' Studium Generale'' in Catania, with the papal recognition arriving ten years later from Pope Eugene IV (18 April 1444). Alfonso V with this gesture wanted to compensate the city (in which there had been recently established the royal court) for moving the Sicilian capital from Catania to Palermo. The activity of the Atheneum actually started a year later, in 1445, with six professors and ten students. The first four faculties were Medicine, Philosophy, Canon and Civil Law and Theology. Lessons were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized Author citation (botany), author abbreviations. These were initially based on Authors of Plant Names, Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium (Australian Plant Name Index, APNI). The IPNI database is a collection of the names registered by the three cooperating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Zamiaceae
The Zamiaceae are a family of cycads that are superficially palm or fern-like. They are divided into two subfamilies with eight genera and about 150 species in the tropical and subtropical regions of Africa, Australia and North and South America. The Zamiaceae, sometimes known as zamiads, are perennial, evergreen, and dioecious. They have subterranean to tall and erect, usually unbranched, cylindrical stems, and stems clad with persistent leaf bases (in Australian genera). Their leaves are simply pinnate, spirally arranged, and interspersed with cataphylls. The leaflets are sometimes dichotomously divided. The leaflets occur with several sub-parallel, dichotomously branching longitudinal veins; they lack a mid rib. Stomata occur either on both surfaces or undersurface only. Their roots have small secondary roots. The coralloid roots develop at the base of the stem at or below the soil surface. Male and female sporophylls are spirally aggregated into determinate cones that gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Bromeliaceae
The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, '' Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss ('' Tillandsia usneoides''), and terrestrial species, such as the pineapple ('' Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte ''Tillandsia'' species tha ...

International Code Of Nomenclature For Algae, Fungi, And Plants
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. For fungi the ''Code'' was revised by the ''San Juan Chapter F'' in 2018. The 2025 edition of ICBN, the ''Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Lichen
A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context. Lichens have since been recognized as important actors in nutrient cycling and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails.

Pier Luigi Nimis
Pier Luigi Nimis is a senior professor of botany (retired in 2023) at the University of Trieste in Italy. He specialises in lichenology and phytogeography, including the uses of lichens as indicators of pollution and devising methods for web-based identification keys. Early life and education Pier Luigi Nimis was the first of two boys, grown up in the small home town of Tarcento in Friuli (NE Italy). His father, Carlo, was an Alpine soldier who survived the Russian expedition of WW2, returned on foot, and became a prosperous baker; his mother, Matilde, was a popular teacher who taught whole generations of young people. Fascinated from a young age by insects, the young Nimis built a remarkable collection of more than 10.000 specimens from the surroundings of his village, which, however, was swept away by the 1976 Friuli earthquake. Nimis studied at the Liceo Classico Jacopo Stellini in Udine, after which he went to the University of Trieste, where he worked on a thesis on the thor ...
