“…Epiphytes represent up to 25 percent of the vascular plant diversity in wet Neotropical forests (Gentry & Dodson 1987). Angiosperm epiphytic communities in Neotropical forests are highly diverse in species richness, but dominated by a few monocotyledonous families (e.g., Orchidaceae, Bromeliaceae, and Araceae), which may locally comprise up to two-thirds of the epiphyte community (Ingram et al 1996, Kreft et al 2004, Benavides et al 2005, Wester et al 2011. Most epiphytes are herbaceous plants that spend their whole life (holo-epiphytes) or part of it (hemi-epiphytes) on their host trees (phorophytes), which they use as mechanical support (Benzing 1990).…”

Association between rainfall seasonality and the flowering of epiphytic plants in a Neotropical montane forest

The association between the reproductive phenology of epiphytic communities with environmental and ecological factors remains largely unexplored. Because epiphytes depend on environmental moisture, seasonal changes in moisture conditions likely act as the primary determinants of their reproductive timing. We examined whether water limitation or pollinator competition structures the flowering phenologies of an epiphytic community in a seasonal mountain forest in Costa Rica. Additionally, we addressed the environmental factors that might trigger floral induction. Using a 24‐month dataset of bimonthly flowering records from 104 species, we found high seasonality of flowering at the species level but somewhat lower seasonality at the community level. The flowering mid‐dates of most epiphytes, particularly from monocotyledonous species, occurred during the wettest months, as predicted if water limitation structures flowering. The increased moisture and nutrient availability during the rainy season give epiphytes the resources needed to complete floral development and anthesis, and later fruit and seed maturation. The observed flowering pattern of epiphytes coincides with reproductive patterns of terrestrial herbs and shrubs from seasonal tropical ecosystems, and suggests shared constraints to sexual reproduction in both ecological guilds under similar climatic conditions. In contrast, flowering patterns of congeneric epiphytes in the same pollination guild mostly did not follow the expectations of a pollinator competition scenario. Finally, we discuss the possible combined effect of precipitation, temperature, and daily insolation on floral induction of epiphytic plants.

“…Nat. 39(151):218-227, abril-junio de 2015 Las epifitas vasculares constituyen entre el 10 y el 25 % de la flora local en las franjas de bosque tropical lluvioso a premontano (Nieder, et al, 2001;Wester, et al, 2011), mientras que en los bosques montanos pueden alcanzar el 50 % (Kelly, et al, 1994). Estas plantas están representadas por 27.614 especies, 913 géneros y 73 familias (Zotz, 2013), de las cuales las Orchidiaceae, Araceae, Bromeliaceae, Piperaceae, Gesneriaceae, Melastomataceae y Ericaceae son las más diversas (Gentry & Dodson, 1987;Benavides, et al, 2006).…”

ResumenSe estudió la diversidad, la densidad poblacional y la distribución espacial y vertical de las especies de Columnea (Gesneriaceae) en la Reserva Natural Río Ñambí en el suroccidente de Colombia. Se ubicaron 100 cuadrantes (10 x 10 m) con el fin de cuantificar la diversidad alfa, la densidad y los patrones de distribución vertical y espacial de las especies de Columnea. La diversidad y la densidad poblacional de cada especie se analizaron con relación a la elevación. Se encontraron 15 especies de Columnea entre los 1.100 y los 1.500 msnm. La densidad de las especies varió con la elevación y fue mayor entre los 1.100 y los 1.300 msnm, con un patrón de distribución espacial agregado. La riqueza varió entre 10 y 12 especies por franja altitudinal, mientras que la diversidad alfa se redujo entre los 1.400 y los 1.500 msnm. La similitud en la composición de especies entre los sitios fue baja, lo que indica una gran diversidad beta para este ensamble. Los resultados de este estudio indican que la Reserva Natural Río Ñambí presenta la riqueza de Columnea más alta registrada para cualquier localidad hasta el momento. Se discuten las diferencias en la densidad y la distribución vertical de las especies y su relación con sus polinizadores y dispersores.Palabras clave: Chocó biogeográfico, Columnea, densidad, diversidad, distribución espacial. Diversity, population density and spatial distribution of Columnea (Gesneriaceae) in the Río Ñambí natural reserve, Nariño, Colombia AbstractWe studied the diversity, population density and vertical and spatial distribution of the species of Columnea in the Río Ñambí natural reserve, southwestern Colombia. We divided the area under study in 100 plots (10 x 10 m) in order to quantify the alpha diversity, the density, and the vertical and spatial distribution pattern of Columnea species. The diversity and population density of each species were analyzed according to the elevation. Fifteen species of Columnea were recorded in altitudes ranging from 1100 to 1500 m.a.s.l. Species density varied with elevation and was highest between 1100 and 1300 m.a.s.l., showing a clumped spatial distribution pattern. Species richness varied between 10 and 12 species per altitudinal belt, while the alpha diversity decreased between 1400 and1500 m.a.s.l. The similarity of species composition was low among sites indicating a high beta diversity for this assemblage. The results of this study showed that the Río Ñambí natural reserve exhibits the highest Columnea richness recorded for a locality to date. We discuss here the differences in density and vertical distribution of Columnea species and their relationship with pollinators and dispersers.
