Ficus Crassiuscula
''Ficus crassiuscula'' is a species of flowering plant in the family Moraceae, native to Central America (Guatemala, Honduras, Belize, Nicaragua, Costa Rica, Panama) and north-western parts of South America (Colombia, Ecuador, Peru and Venezuela). Taxonomy ''Ficus crassiuscula'' was first described in 1917. In the 1960 ''Flora of Panama'' Gordon P. DeWolf Jr. considered this species to be a synonym of the non-climbing ''F. insipida'', but this taxonomic interpretation has not been followed by subsequent authorities. With about 750 species, ''Ficus'' (Moraceae) is one of the largest angiosperm genera. ''F. insipida'' is classified in subgenus '' Pharmacosycea'', section ''Pharmacosycea'', subsection ''Bergianae'', along with ''F. adhatodifolia'', ''F. carchiana'', ''F. gigantosyce'', ''F. insipida'', ''F. lapathifolia'', ''F. mutisii'', ''F. oapana'' (''spec. nov.''? ined.), ''F. obtusiuscula'', ''F. piresiana'', ''F. rieberiana'' and ''F. yoponensis''.

Otto Warburg (botanist)
Otto Warburg (20 July 1859 – 10 January 1938) was a German-Jewish botanist. He was also a notable industrial agriculture expert, and president of the Zionist Organization from 1911 to 1921. Biography Otto Warburg was born in Hamburg on 20 July 1859 to a family whose ancestors came to Germany in 1566, possibly from Bologna. He completed his studies at the Johanneum Gymnasium in Hamburg in 1879, and continued his education in the field of botany at the University of Bonn which he left after one semester to move to the University of Berlin, and later to University of Strasbourg, where he received his Ph.D in 1883. He went on to study chemistry in Munich and physiology in Tübingen with Wilhelm Pfeffer. In 1885 he embarked on a 4-year expedition to Southern and Southeastern Asia, ending in Australia in 1889. Warburg's cremated remains were brought to Israel and buried at Kibbutz Degania in 1940. Zionism and scientific career In 1911 Warburg was elected president of the Zionis ...

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Journal Of Ecology
The ''Journal of Ecology'' is a bimonthly peer-reviewed scientific journal covering all aspects of the ecology of plants. It was established in 1913 and is published by Wiley-Blackwell on behalf of the British Ecological Society. The journal publishes papers on plant ecology (including algae) in both terrestrial and aquatic ecosystems. In addition to population and community ecology, articles on biogeochemistry, ecosystems, microbial ecology, physiological plant ecology, climate change, molecular genetics, mycorrhizal ecology, and the interactions between plants and organisms such as animals or bacteria, are published regularly. Besides primary research articles, it publishes "Essay Reviews" and "Forum" articles. In 2008, the first papers in a new series called "Future Directions" were published. These short papers are intended to stimulate debate as to where a field within plant ecology is going, or needs to go. In addition, the journal contains a long-running series on the "Bio ...

Hemiepiphyte
A hemiepiphyte is a plant that spends part of its life cycle as an epiphyte. The seeds of primary hemiepiphytes germinate in the canopy and initially live epiphytically. They send roots downward, and these roots eventually make contact with the ground. Secondary hemiepiphytes are root-climbers that begin as rooted vines growing upward from the forest floor, but later break their connection to the ground. When this happens, they may send down long roots to the ground.Mayo et al. "Araceae" in Kubitzki (1998b ''The families and genera of vascular plants''): "The root climbers and hemiepiphytes normally grow in humid forests, often very high in the canopy. When losing connection with the forest floor, they may send down long roots to the ground; such plants may be referred to as secondary hemiepiphytes. Hemiepiphytes and root climbers cling tightly to the bark of the host with negatively phototropic roots. Skototropism, an orientation movement towards a well-defined dark area, ha ...

Cladistics
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. R ...

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

Ficus Yoponensis
''Ficus yoponensis'' is a species of fig tree found in Central and South America. It can grow to heights of tall, having a trunk diameter of . The trunk is buttressed, light grey in colour and reasonably smooth. Its petioles are long, the stipules are straight and long. The leaves and stems are hairless. The leaves are long and wide, but larger in juveniles, being up to long and wide. The time at which they flower varies between individuals, but each tree tends to flower at a similar time each year. As in all figs, the flowers are enclosed inside the fig and can only be accessed by fig wasps, which enter to pollinate the flowers and lay their own eggs. The resulting fruit grows to in diameter and turns from green to purple with maturity. On average in Panama, ''F. yoponensis'' produce a new flush of leaves every 20 weeks and flower every 25 weeks. The species is similar in appearance to ''Ficus insipida'' but has smaller leaves, stipules and fruits and only occurs in prim ...

Ficus Rieberiana
''Ficus'' ( or ) is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes in the family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig (''F. carica'') is a temperate species native to southwest Asia and the Mediterranean region (from Afghanistan to Portugal), which has been widely cultivated from ancient times for its fruit, also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood. However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout the tropics, both as objects of worship and for their many practical uses. Description ''Ficus'' is a pantropical genus of trees, shrubs, and vines occupying a wide variety of ecological niches; most are evergreen, but ...
