Non-equilibrium dynamics and floral trait interactions shape extant angiosperm diversity. [PDF]

, 2016
Why are some traits and trait combinations exceptionally common across the tree of life, whereas others are vanishingly rare? The distribution of trait diversity across a clade at any time depends on the ancestral state of the clade, the rate at which ...

Reproductive traits and floral visitors of Aechmea distichantha plants growing in different habitats of a South American xerophytic forest [PDF]

, 2018
Aechmea distichantha, a widely-distributed facultative epiphytic bromeliad species, is present from rainforests to xerophytic forests. At its southernmost distribution (Humid Chaco) it grows in the understory and forest edges.

Seed development and its relationship to fruit structure in species of Bromelioideae (Bromeliaceae) with fleshy fruits

, 2020
In Bromeliaceae, fruit type and seed morphology have been used to distinguish the subfamilies. We studied seed and fruit development of three species of Bromelioideae (Aechmea bromeliifolia, Billbergia distachia and Neoregelia bahiana) relating seed ...

Morphological Phylogenetic Analysis of Two Early-Diverging Genera of Bromelioideae (Bromeliaceae)

Rodriguésia
Bromelia includes 66 species, grouped in three subgenera: Bromelia, Distiacanthus and Karatas. The genus is one of the earlier divergent groups within Bromelioideae, a subfamily with innumerable problems of generic delimitation.

Functional types in the Bromeliaceae: relationships with drought‐resistance traits and bioclimatic distributions

Functional Ecology, Volume 31, Issue 10, Page 1868-1880, October 2017., 2017
Plain Language Summary Summary Neotropical Bromeliaceae occupy an exceptional diversity of habitats. The five principal functional types, which are defined by innovations such as Crassulacean acid metabolism (CAM), epiphytism, the tank growth form and neoteny, display distinct ecological water‐use strategies.

High Species Diversity in Fleshy-Fruited Tropical Understory Plants [PDF]

, 2001
Key innovations may increase the number of taxa in a clade that possesses the proposed innovation in comparison to its sister group that lacks the trait through either increased speciation or reduced extinction rates.
