Loss of YABBY2-Like Gene Expression May Underlie the Evolution of the Laminar Style in Canna and Contribute to Floral Morphological Diversity in the Zingiberales. [PDF]

open access: yes, 2015
The Zingiberales is an order of tropical monocots that exhibits diverse floral morphologies. The evolution of petaloid, laminar stamens, staminodes, and styles contributes to this diversity.

Quimiotaxonomia da superordem Zingiberiflorae (sensu Dahlgren) I: flavonóides como marcadores quimiossistemáticos Chemotaxonomy of superorder Zingiberiflorae [sensu Dahlgren] I: flavonoids

open access: yesActa Botânica Brasílica, 1993
A análise das características flavonoídicas da ordem Zingiberales (superordem Zingiberiflorae, Monocotyledonae) reforçou a separação das suas famílias em dois grupos: grupo I (Strelitziaceae, Heliconiaceae, Musaceae e Lowiaceae) e grupo II (Zingiberaceae,

Isolated Grauer's gorilla populations differ in diet and gut microbiome

open access: yesMolecular Ecology, Volume 32, Issue 23, Page 6523-6542, December 2023., 2023
Abstract The animal gut microbiome has been implicated in a number of key biological processes, ranging from digestion to behaviour, and has also been suggested to facilitate local adaptation. Yet studies in wild animals rarely compare multiple populations that differ ecologically, which is the level at which local adaptation may occur.

Structure and composition of the ground-herb community in a terra-firme Central Amazonian forest Estrutura e composição da comunidade herbácea terrestre em uma floresta de terra-firme da Amazônia Central

open access: yesActa Amazonica, 2004
The herb community of tropical forests is very little known, with few studies addressing its structure quantitatively. Even with this scarce body of information, it is clear that the ground herbs are a rich group, comprising 14 to 40% of the species ...

The effect of elevation on species richness in tropical forests depends on the considered lifeform: results from an East African mountain forest [PDF]

open access: yes, 2019
Elevation gradients in tropical forests have been studied but the analysis of patterns displayed by species richness and elevation have received little attention.

Pollination syndromes in African Marantaceae [PDF]

open access: yesAnnals of Botany, 2009
The Marantaceae (550 spp.) is the most derived family in the order Zingiberales and exhibits a complex explosive pollination mechanism. To understand the evolutionary significance of this unique process of pollen transfer, comparative morphological and ecological studies were conducted in Gabon.During a total stay of 11 months, 31 species of ...

Phylogeny and classification of Marantaceae [PDF]

open access: yesBotanical Journal of the Linnean Society, 2001
Abstract Relationships of Marantaceae were estimated from nucleotide sequence variation in the rps 16 intron (plastid DNA) and from morphological characters. Fifty-nine species (21 genera) formed the ingroup, and 12 species (12 genera) of other Zingiberales formed the outgroup. There is no support for the traditional subdivision of Marantaceae into a

The fallow period as a weed-break in shifting cultivation (tropical wet forests) [PDF]

open access: yes, 1995
In the wet tropics weeds can grow all year round. In shifting cultivation systems the fallow period is used to restrain the development of weeds because they threaten the re-use of the land.
