Understanding which orchid mycorrhizal fungi (OMF) are needed to support orchid growth is critical for their conservation. We used DNA sequencing and network analysis of OMF collections from the North American Orchid Conservation Center, along with published sequences, to compare the OMF associated with 28 species and 4 natural hybrids in the genus Platanthera . We found that relatedness of orchid species was generally a poor...

Taxonomic ambiguity, frequent hybridization, and limited resolution of species boundaries continue to constrain orchid conservation strategies. In this study, we employed population genomic analyses across nine taxa of Platanthera native to eastern North America to critically reassess species boundaries and evaluate spatial patterns of genetic structure. Utilizing 3RADseq-derived SNP datasets, we delineated species limits, ide...

Survival and reproduction are the two primary life‐history traits essential for species’ persistence; however, the environmental conditions that support each of these traits may not be the same. Despite this, reproductive requirements are seldom considered when estimating species’ potential distributions. We sought to examine potentially limiting environmental factors influencing the distribution of an oviparous reptile of con...
