Root turnover and productivity of coniferous forests
(Martinus Nijhoff/Dr. W. Junk Publishers; Martinus Nijhoff/Dr W. Junk Publishers ; Springer Science+Business Media, 1983-02)
Fine roots and mycorrhizae have recently been shown to produce a major portion of the organic matter entering decomposition. Roots and mycorrhizae constitute 63 to 70% of total net primary production in Douglas-fir and ...
Two new species of Galphimia (Malpighiaceae), and a key to the Mexican species with deciduous petals
(2005-02-07)
Galphimia mirandae and G. oaxacana, two new Mexican species with deciduous petals, are described and illustrated. A key to all 14 Mexican species of Galphimia with deciduous petals is presented.
Recent phylogeographic structure of a “weedy” widespread Neotropical tree species, Cordia alliodora (Boraginaceae)
(Blackwell, 2013)
Aim Although hundreds of tree species have broad geographic ranges in the Neotropics, little is known about how such widespread species attained disjunct distributions around mountain, ocean and xeric barriers. Here, we ...
Stigmaphyllon hispidum (Malpighiaceae), a new species from Bahia, Brazil
(2000-06-30)
Stigmaphyllon hispidum, a new species of Malpighiaceae, is described from Bahia, Brazil, where it was collected in a remnant of coastal forest, a vegetation type called Mata Atlantica. Its floral structure and adaxial ...
The status of Agardhiella tenera and Agardhiella baileyi (Rhodophyta, Gigartinales)
(Kluwer Academic Publishers; Dr. W. Junk B.V. Publishers ; Springer Science+Business Media, 1973-10)
Evidence is presented to support the placement of Agardhiella tenera in Solieria (as S. tenera comb. nov.) for the reason that a large fusion cell is present in the center of the cystocarp. Since A. tenera is the type ...
Anonymous and EST-based microsatellite DNA markers that transfer broadly across the fig genus (Ficus, Moraceae)
(2012)
• Premise of the study: We developed a set of microsatellite markers for broad utility across the species-rich pantropical tree genus Ficus (fig trees). The markers were developed to study population structure, hybridization, ...
Three new species of Bunchosia (Malpighiaceae): B. cuscana, B. hedraiophylla, and B. neillii
(2015-07-15)
Three new species of Bunchosia are described and illustrated. Bunchosia cuscana from Andean Peru bears two pseudoracemes per leaf axil, instead of the more common single inflorescence, and is compared with B. argentea with ...
Characterization of twenty-six microsatellite markers for the tropical pioneer tree species Cecropia insignis Liebm (Urticaceae)
(Springer, 2014-12)
Cecropia insignis is an ecologically important Neotropical pioneer tree and major vertebrate food source. Although this species is relatively common in faunally intact tropical rainforests, its population dynamics may be ...
Comment on “Persistent effects of pre-Columbian plant domestication on Amazonian forest composition”
(American Association for the Advancement of Science, 2017-10-20)
Levis et al. (Research Articles, 3 March 2017, p. 925) concluded that pre-Columbian tree
domestication has shaped present-day Amazonian forest composition.The study, however,
downplays five centuries of human influence ...
