Eighteen new species of Neotropical Costaceae (Zingiberales).

In preparation for a full taxonomic revision of the Neotropical genera of Costaceae (i.e., , , , and ), we present the description of 17 new species of Neotropical and one new species of the Neotropic endemic genus with notes on their distribution and ecology, vernacular names (when known), and diagnostic characters for identification.

The genetic mechanisms underlying the convergent evolution of pollination syndromes in the Neotropical radiation of L.

Selection together with variation in floral traits can act to mold floral form, often driven by a plant's predominant or most effective pollinators. To investigate the evolution of traits associated with pollination, we developed a phylogenetic framework for evaluating tempo and mode of pollination shifts across the genus L., known for its evolutionary toggle between traits related to bee and bird pollination.

The influence of chronotype on the body mass index of U.S. college students.

Objectives: The relationship between a college student's chronotype and body mass index (BMI) is important to understand for university decision makers who want to build healthy and inclusive academic communities. This study aimed to evaluate how a student's chronotype influences their BMI.

Material And Methods: Participants were college students from Oral Roberts University (n=384) with a mean age of 18.

To which world regions does the valence-dominance model of social perception apply?

Over the past 10 years, Oosterhof and Todorov's valence-dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear whether these findings apply to other regions.

Unraveling the Spiraling Radiation: A Phylogenomic Analysis of Neotropical L.

The family of pantropical spiral gingers (Costaceae Nakai; 125 spp.) can be used as a model to enhance our understanding of the mechanisms underlying Neotropical diversity. Costaceae has higher taxonomic diversity in South and Central America ( 72 Neotropical species, 30 African, 23 Southeast Asian), particularly due to a radiation of Neotropical species of the genus L.
