From dusk till dawn: nocturnal and diurnal pollination in the epiphyte Tillandsia heterophylla (Bromeliaceae)

In order to compare the effectiveness of diurnal and nocturnal pollinators, we studied the reproductive biology and pollinators of Tillandsia heterophylla E. Morren, an epiphytic tank bromeliad endemic to southeastern Mexico. Since anthesis in T. heterophylla is predominantly nocturnal but lasts until the following day, we hypothesised that this bromeliad would receive visits from both diurnal and nocturnal visitors, but that nocturnal visitors would be the most effective pollinators, since they arrive first to the receptive flower, and that bats would be the most frequent nocturnal visitors, given the characteristics of the nectar. Flowering of T. heterophylla began in May and lasted until July. The species is fully self-compatible, with an anthesis that lasts for ca. 15-16 h. Mean volume of nectar produced per flower was 82.21 μl, with a mean sugar concentration of 6.33%. The highest volume and concentration of nectar were found at 20:00 h, with a subsequent decline in both to almost zero over the following 12-h period. T. heterophylla has a generalist pollination system, since at least four different morphospecies of visitors pollinate its flowers: bats, moths, hummingbirds and bees. Most of the pollinating visits corresponded to bats and took place in the early evening, when stigma receptivity had already begun; making bats the probable pollinator on most occasions. However, diurnal pollinators may be important as a 'fail-safe' system by which to guarantee the pollination of T. heterophylla.

“…Species in this family are pollinated mostly by vertebrates, and hummingbirds are their most frequent visitors (ZANELLA et al 2012). The effects of plantpollinator interaction on plant reproduction, however, are still poorly understood (ANTONELLI & SANMARTÍN 2011, KAMKE et al 2011, ZANELLA et al 2012. Species in this family have two main breeding systems, and self-compatibility (SC) is more common than self-incompatibility (SI).…”

“…Among epiphytic bromeliads, the most common reproductive system is self‐fertilization (Bush & Beach, ; Aizen & Feinsinger, ; Canela & Sazima, ; Lasso & Ackerman, , ; Ramírez‐Morillo et al ., , ; Cascante‐Marin et al ., , ; Cascante‐Marín et al ., ; Matallana et al ., ; Kamke et al ., ; Paggi et al ., ; Mondragón et al ., ).

“…Experimental studies conducted in 88 species of bromeliads showed that 66% are self‐compatible (58 species), 8% are self‐compatible but pollinator dependent and 25% are self‐incompatible. Among the 58 self‐compatible species, 36 species have a high proportion of fruit set produced by autonomous self‐fertilization (Bush & Beach, ; Aizen & Feinsinger, ; Canela & Sazima, ; Lasso & Ackerman, , ; Ramírez‐Morillo, Fernández‐Concha & May, ; Cascante‐Marin et al ., , ; Ramírez‐Morillo et al ., ; Cascante‐Marín, Wolf & Oostermeijer, ; Matallana et al ., ; Kamke et al ., ; Paggi et al ., ; Mondragón, Valverde & Hernández‐Apolinar, ). Studies describing the breeding system of a community of epiphytes are scarce (Bush & Beach, ; Matallana et al ., ), making it possible that the overall pattern of the distribution of breeding systems among bromeliads could be biased towards self‐compatible species.…”

Are breeding system and florivory associated with the abundance ofTillandsiaspecies (Bromeliaceae)?

Plant species abundance is partly determined by reproductive success and the factors that limit this success. We studied the flowering phenology, breeding systems and florivory in a community of seven epiphytic Tillandsia spp. in a tropical dry forest in central Mexico. Flowering periods were distributed throughout the year, and corolla sizes suggested that most species share pollinators. The most common breeding system was self‐incompatibility (Tillandsia achyrostachys, T. caput‐medusae and T. hubertiana), T. lydiae was infertile, T. circinnatioides was partially self‐compatible and T. recurvata and T. schiedeana were self‐compatible with high autonomous self‐pollination. Floral morphology suggests that delayed selfing occurs in the autonomous self‐pollinated species, and separation between stigma and stamens could result in self‐pollination in the remaining species being avoided. Less than 5% of the inflorescences in the most abundant species (T. recurvata) suffered damage by florivores, but > 40% of inflorescences were damaged in the other species. In damaged inflorescences, fruit set decreased by up to 89%. Our data show that the dominant species (T. recurvata) is autogamous and its reproductive success is slightly reduced by resource constraints and florivory. In the less abundant species, resource limitation and florivory dramatically reduced reproductive success, but the strength of these limiting factors is season dependent. © 2014 The Linnean Society of London, Botanical Journal of the Linnean Society, 2015, 177, 50–65.
