Floristic classifications and bioregionalizations are not predictors of intra-specific evolutionary patterns.

The relationship between intra-specific and inter-specific patterns and processes over evolutionary time is key to ecological investigations. We examine this relationship taking an approach of focussing on the association between vegetation and floristic classifications, summaries of inter-specific processes, and intra-specific genetic structuring. Applying an innovative, multispecies, and standardised population genomic approach, we test the relationship between vegetation mapping schemes and structuring of genetic variation across a large, environmentally heterogenous region in eastern Australia.

Culture age of Tulasnella affects symbiotic germination of the critically endangered Wyong sun orchid Thelymitra adorata (Orchidaceae).

Orchids (Orchidaceae) are dependent on mycorrhizal fungi for germination and to a varying extent as adult plants. We isolated fungi from wild plants of the critically endangered terrestrial orchid Thelymitra adorata and identified them using a multi-region barcoding approach as two undescribed Tulasnella species, one in each of phylogenetic group II and III (OTU1) of the Tulasnellaceae. Using symbiotic propagation methods, we investigated the role of Tulasnella identity (species and isolate) and age post isolation, on the fungus's ability and efficacy in germinating T.
