Floral Display And Habitat Fragmentation: Effects On The Reproductive Success Of The Threatened Mass-Flowering Conospermum Undulatum (Proteaceae) [Dataset], Nicola Delnevo, Eddie Van Etten, Margaret Byrne, William Stock

Research Datasets

1. Fragmentation of natural vegetation is currently one of the largest threats to plant populations and their interactions with pollinators. Plant reproductive susceptibility to habitat fragmentation has been investigated in many species; however, the response of wild mass-flowering species is poorly known, with research limited to mainly boreal plant species.

2. Here we studied twelve remnant populations of the threatened mass-flowering shrub Conospermum undulatum in the southwest Australian biodiversity hotspot, each presenting different population size, level of isolation, and floral display. We assessed the impact of fragmentation on: 1) fruit and seed production; and 2) seed germination. To gain a …

Isolation, Characterization, And Cross-Amplification Of 20 Microsatellite Markers For The Rare Conospermum Undulatum (Proteaceae) [Dataset], Nicola Delnevo, Andrea Piotti, Eddie J. Van Etten, William D. Stock, Margaret Byrne

Research Datasets

Premise of the study: Recent habitat fragmentation is posing a risk to the wavy-leaved smokebush, Conospermum undulatum, a rare plant species endemic to the south-western Western Australia. Microsatellites markers are required to characterize the genetic diversity and structure of the species for conservation purposes and to facilitate ecological studies. Methods and Results: Illumina MiSeq high-throughput sequencing was used to develop 20 novel microsatellite markers for C. undulatum. Polymorphism at each locus was assessed using 72 individuals from three natural populations. Nineteen markers were polymorphic, with the number of alleles per locus ranging from two to 21, and observed and expected …
