2013 36E(1) 76-91 Julio Andrés Sierra-Giraldo, David Sanin, Luis Fernando Coca, Juan Mauricio Posada-Herrera Araceae in a High Andean Forest of the Colombian Occidental Cordillera (Natural National Park Tatam (Read)
ABSTRACT: Colombia represents the highest register of Araceae species by area. However, across the country there is a high sampling bias, with records especially lacking in the Andes and the biogeographic region of Choc?. Therefore, a study of the aroids was developed in the oriental slope of the Colombian Western Cordillera in the Natural National Park Tatam? using plots every 200m in an altitudinal range between 2400 ? 3000m asl. Two genera (Anthurium and Chlorospatha) and 14 species were recorded. Of these 71.42% had a terrestrial habit, 21.43% were hemiepiphyte and 7.14% epiphyte. The genus with the largest number of species (12) and the widest distribution was Anthurium. One species, Anthurium longegeniculatum, was present through all the altitudinal gradient studied. The highest species diversity was found in the plots located between 2400 ? 2600 m. The known distribution of nine species of Anthurium and two species of Chlorospatha is enlarged in the Natural National Park Tatam?. These results highlight the fact that it?s necessary to increase the sampling and the floristic researches on Araceae, due its complexity, high diversity and endemism in the Neotropics, especially in the Andes.

2014 37E(1) 4-10 Román Felipe Díaz-Ayala, Luisa Fernanda Hurtado, Julio Andrés Sierra-Giraldo First record of Anura (Dendropsophus columbianus -Anura: Hylidae-) as floral visitors of Araceae (Zantedeschia aethiopica (L.) Spreng) (Read)
ABSTRACT: No amphibian has yet been reported among the many interactions between Araceae and their flower visitors. This paper reports the possible use of the inflorescences of Zantedeschia aethiopica as a habitat for Dendropsophus columbianus, and suggests that further exploration of this kind of interaction would be of interest.

2016 39(2) 127-133 Julio Andrés Sierra-Giraldo, A. Lorena Hernandez-G, Monica M. Carlsen New distribution record for Anthurium zuluagae Croat (Araceae) in Colombia (Buy)
ABSTRACT: Anthurium zuluagae is recorded in the municipality of Gachalá (Department of Cundinamarca), in the Colombian Eastern Cordillera. This new record expands its distribution area in Colombia. Anthurium zuluagae is an uncommon and poorly known species. Therefore, more research on its population status and ecological characteristics, such as type of pollinators and dispersers, is needed as well as to understand the distribution patterns of the Colombian aroids particularly in the Eastern Cordillera.
