Effects of habitat fragmentation on the reproductive success of the nectar-producing orchid Gymnadenia conopsea and the nectarless Orchis mascula KU Leuven
Habitat fragmentation decreases plant population sizes and increases spatial isolation, which hampers the exchange of seeds and pollen between fragmented populations. This may result in decreased population viability. We compared the effects of population size and isolation on the reproductive success of two orchid species, Gymnadenia conopsea (nectar-producing) and Orchis mascula (nectarless) growing in highly fragmented calcareous grassland in ...
