Aim

Palms are an iconic, diverse and often abundant component of tropical ecosystems that provide many ecosystem services. Being monocots, tree palms are evolutionarily, morphologically and physiologically distinct from other trees, and these differences have important consequences for ecosystem services (e.g., carbon sequestration and storage) and in terms of responses to climate change. We quantified global patterns of tree palm relative abundance to help improve understanding of tropical forests and reduce uncertainty about these ecosystems under climate change.

Location

Tropical and subtropical moist forests.

Time period

Current.

Major taxa studied

Palms (Arecaceae).

Methods

We assembled a pantropical dataset of 2,548 …

Typification Of The Genus Dicaryum (Verbenaceae), John J. Pipoly Iii, Jon M. Ricketson

Marine & Environmental Sciences Faculty Articles

The genus Dicaryum Willd. ex Roem. & Schult. was described in 1819 and does not have a type species. Two species were described, and one, D. subdentatum Willd. ex Roem. & Schult., is better selected as the type because the other species, D. serrulatum Willd. ex Roem. & Schult., is not a Verbenaceae but rather a Primulaceae-Myrsinoideae and belongs to Geissanthus Hook. f. Given the circumstances, we choose D. subdentatum as the type species of Dicaryum, which is a synonym of Citharexylum ilicifolium Kunth.

A New Species Of Cybianthus (Myrsinaceae) From The Cordillera Del Condor (Ecuador And Peru), John J. Pipoly Iii, Jon M. Ricketson

Marine & Environmental Sciences Faculty Articles

Cybianthus condorensis Pipoly & Ricketson, a new species from the Cordillera del Condor of Ecuador and Peru, is described herewith. Because of its alternate, coriaceous, and revolute leaves; scattered to densely appressed lepidote branchlets, inflorescence rachises, and calyces; subsessile pistillate flowers; and sandy habitat, this species is easily recognized.

Lineages tend to retain ecological characteristics of their ancestors through time. However, for some traits, selection during evolutionary history may have also played a role in determining trait values. To address the relative importance of these processes requires large-scale quantification of traits and evolutionary relationships among species. The Amazonian tree flora comprises a high diversity of angiosperm lineages and species with widely differing life-history characteristics, providing an excellent system to investigate the combined influences of evolutionary heritage and selection in determining trait variation. We used trait data related to the major axes of life-history variation among tropical trees (e.g. growth …

While Amazonian forests are extraordinarily diverse, the abundance of trees is skewed strongly towards relatively few ‘hyperdominant’ species. In addition to their diversity, Amazonian trees are a key component of the global carbon cycle, assimilating and storing more carbon than any other ecosystem on Earth. Here we ask, using a unique data set of 530 forest plots, if the functions of storing and producing woody carbon are concentrated in a small number of tree species, whether the most abundant species also dominate carbon cycling, and whether dominant species are characterized by specific functional traits. We find that dominance of forest …

Lectotypification Of Ardisia Dawnaea (Myrsinaceae), Jon M. Ricketson, John J. Pipoly Iii

Marine & Environmental Sciences Faculty Articles

A taxonomically complex issue regarding Ardisia gracilis Lace, A. dawnaea C. E. Parkinson, and A. dawnensis M. P. Nayar & G. S. Giri (Myrsinaceae) from Burma [Myanmar] is discussed and resolved with the lectotypification of A. dawnaea.

A New Species Of Cybianthus (Myrsinaceae) From Tobago And Venezuela, John J. Pipoly Iii, Jon M. Ricketson

Marine & Environmental Sciences Faculty Articles

ybianthus pittierianus Pipoly & Ricketson (Myrsinaceae) is described from Tobago, and its taxonomic relationships are discussed. This species is often confused with C. rostratus (Hassk.) G. Agostini owing to its free portions of the filaments being longer than the anthers, and leaves with similar elliptic shapes and with petioles less than 1.2 cm. However, C. pittierianus is easily distinguished from C. rostratus by the former's leaf blade apices abruptly acute to short-acuminate (vs. long-acuminate to caudate), with secondary veins in 18 to 24 pairs (vs. 28 to 32 pairs), corollas 2.4–3 mm (vs. 2.1–2.5 mm), and corolla lobes chartaceous (vs. …

A New Combination In Ardisia (Myrsinaceae) From Vietnam, Jon M. Ricketson, John J. Pipoly Iii

Marine & Environmental Sciences Faculty Articles

The lectotypification of Ardisia tinctoria Pit. and subsequent reidentification of the type material as A. quinquegona Blume subsp. quinquegona resulted in two collections being orphaned under the name A. tinctoria var. microcarpa Pit. We elect to elevate the variety name A. tinctoria var. microcarpa and, here, propose the following new combination, A. microcarpa (Pit.) Ricketson & Pipoly, comb. et stat. nov., to accommodate these orphaned collections.
