Cím:	Honeybee (Apis mellifera) mediated increased reproductive success of a rare deceptive orchid / É. Biró, J. Bódis, T. Nagy, J. Tökölyi, A. Molnár V.

Megjegyzések:	Honeybees are the most numerous and significant among insect pollinators, but despite their significance their potential role in increasing the reproductive success of threatened European orchids remains largely unexplored. In this study we aim to evaluate the effect of apiary proximity on the fructification rate of the rare and endangered Adriatic Lizard Orchid (Himantoglossum adriaticum H. Baumann). To do so, first we quantified the reproductive success (fruit set) of the Adriatic Lizard Orchids in a Hungarian population in close proximity to a honeybee apiary at Nagytevel. Then we compared the reproductive success in this population to the reproductive success in 3 other Hungarian, 4 Croatian populations (observed during the same year, 2013) and further 4 populations from Hungary (studied in previous years, 1992?2011) with no apiaries in the close proximity of these. The realised 61.7 % fruit set at Nagytevel is the highest reproductive success ever recorded for this species. The importance of apiaries is further emphasised by the fact that the reproductive success of Lizard Orchid individuals decreased significantly with increasing distance from the apiary. Our results provide empirical support for the conservation importance of apiculture and suggest promising results for practical application of apiaries in the conservation of of deceptively pollinated orchids characterised by lower fruit set (e.g. Orchis, Anacamptis, Himantoglossum).

Cím:	Precipitation and timing of flowering in ghost orchids (Epipogium aphyllum Sw.) / Nagy T., Nótári K., Takács A., Malkócs T., Tökölyi J., Molnár V. A.
Dátum:	2018

Megjegyzések:	The rare, fully mycoheterotrophic Ghost Orchid, Epipogium aphyllum is only visible dur- ing its short flowering and fruiting season, which lasts for a few weeks between May and October. Due to the apparent unpredictability of its flowering, decades may pass between subsequent observations at the same locality. The factors affecting timing of flowering in this enigmatic species remain largely unexplored. In Hungary, it is an extremely rare species: between 1924 and 2014 only 25 dated observations from 15 locations are known. Hungary is located on the edge of the species' distribution area where higher precipitation may occur only in higher regions of mountains. Hence, the spatial and temporal pattern of precipitation might limit the emergence of generative shoots. In this paper we compared rainfall patterns in relation with the Ghost Orchids' observations to multiannual precipita- tion averages. The year of flowering and the month preceding flowering (but not the year before flowering and the month of flowering) were characterised by significantly more rainfall than the multi-annual average precipitation. These results suggest that the appear- ance of the species in Hungary is precipitation-dependent.
