Background and Aims: A significant proportion of orchid species assigned to subtribe Oncidiinae produce floral oil as a food reward that attracts specialized bee pollinators. This oil is produced either by glabrous glands ...

Nomenclatural amendments and notes are provided for taxa belonging to diverse genera within subtribe Pleurothallidinae (Orchidaceae) in order to comply with the International Code for algae, fungi, and plants. The proposed ...

Microsatellite markers provide high polymorphism levels, useful to study genetic diversity and gene flow patterns in plant populations. Here we develop and characterize microsatellite primers to evaluate patterns of genetic ...

On April 11, 2019, Dr. William Mark Whitten, a prolific neotropical orchid biologist passed away unexpectedly. He leaves an extensive corpus of work focused on (but not limited to) orchid pollination and systematics, ...

Objectives: Although fermented food use is ubiquitous in humans, the ecological and evolutionary factors contributing to its emergence are unclear. Here we investigated the ecological contexts surrounding the consumption ...

Las palmas son uno de los principales componentes de los bosques tropicales; no obstante, existe muy poca información disponible para identificar plántulas. En este trabajo desarrollamos una clave dicotómica con fotografías ...

Most of the world’s land surface is currently under human use and natural habitats remain as fragmented samples of the original landscapes. Measuring the quality of plant progeny sired in these pervasive environments ...

We document here for the first time ultrastructural details of the cellular interaction of Asteridiella callista and its host Stachytarpheta mutabilis var. violacea from Costa Rica. A. callista attaches to the host with ...

The internal temperature of nests largely depends on the materials used in their construction because the characteristics of each material affect the isolation of nest walls. In urban environments, the availability of natural ...

Twelve orchid species previously described in the genus Maxillaria are transferred to Heterotaxis, Inti, Pityphyllum, and Sauvetrea. In addition, 19 new heterotypic synonyms in Maxillariinae are presented; these and a few ...
