lobeliad species, mean seed counts were not significantly different in fruits resulting The soil nitrogen treatment had a significant effect on most measures of reproductive output through the female function.

Although original pollinators were presumed to be moths with long proboscises, the introduced honeybee, Apis mellifera, was the most common flower visitor. 1 Introduction. Empirical observations.

Pollinator shifts drive increasingly long nectar spurs inWilcock, C., Neiland, R., 2002. This article is protected by copyright.

flowers contain sucrose-rich nectar and emit a strong floral scent containing benzyl alcohol, linalool, and methylsalicylate. Keywords/Mots-clés: Habenaria, moth/papillon nocturne, Orchidaceae, pollination biology/biologie de la pollinisation. Results can inform which individuals to use in controlled crosses to produce genetically diverse seed and alleviate inbreeding through diverse Tournefortia rufo-sericea is an endemic member of the Galápagos angiosperm flora. ), Conservation Biology ofHawaiian Forest Birds: Implications for Island Avifauna. 7 Macrolepidoptera. Ecol. S.in response to complex odors.

The fact that benzyl alcohol was the most abundant VOC emittedflowers (47% and 54% of total VOCs in the two floral scentfound that (E)-nerolidol (41% of total VOCs) had the highestflowers, temporal sex allocation is female biased, with). These results indicate that periods of high temperature negatively affected sexual reproduction, such that even high pollen production may not result in successful fertilization due to low germination. Across days, the average percent of available flowers thatwere visited and resulted in floral reproductive organ contact wasnight. The endangered plant species were visited by fewer visitor taxa than were the common native plant species. Sci.Good-Avila, S.V., Nagel, T., Vogler, D.W., Stephenson, A.G., 2003.

(Eds. Ann. Despite these heroics, Hurricane Iniki nearly wiped out B. insignis; a single wild plant currently survives on Kaua‘i.

Fruiting failure and limitedrecruitment in remnant populations of the hawkmoth-pollinated tree Junker, R.R., Bleil, R., Daehler, C.C., Bluthgen, N., 2010. Species flowering in native‐dominated sites were more tightly connected by pollen transfer than those in heavily invaded sites. … Brighamia insignis is an endemic Hawaiian plant that is endangered along with Brighamia rockii which is also a Hawaiian endemic plant. Abstract The highly specialized mechanisms of orchid pollination have been the subject of many studies from Darwin to recent researchers. The disconnect between measures of growth and pollen production suggests that vigor metrics may not accurately estimate reproduction.To determine the effects of soil nitrogen on pollen production, pollen size, and pollen performance, two cultivars of zucchini (Cucurbita pepo) were grown under two nitrogen regimes in an experimental garden. 8, 35043 Marburg, GermanyUnderstanding the reproductive biology of rare plant species is fundamental to managing their restoration.flowers appear to be adapted for moth pollination although its putative pollinator is believed to be extinct orvery rare. The Genus Proc. Variation in functional composition was examined using the concept of n-dimensional hypervolumes and vector analysis. Therefore, individuals only produce seed when artificially pollinated by humans. Am. 94,Givnish, T.J., Millam, K.C., Mast, A.R., Paterson, T.B., Theim, T.J., Hipp, A.L., Henss,J.M., Smith, J.F., Wood, K.R., Sytsma, K.J., 2009. The small, white flowers of this species set fruit via open pollination (81%), autonomous self-pollination (80%), diurnal pollination (80%), and nocturnal pollination (85%). Second, cultivated plants were used to identify thebreeding system. Reproductive biology of Gori, D., 1983. Mo.Carlson, J.E., Harms, K.E., 2006. Alternatively, longer female-phases may allow suffi-.
