Molecular phylogenetic analyses reveal multiple long-distance dispersal events and extensive cryptic speciation in Nervilia (Orchidaceae), an isolated basal Epidendroid genus Open
Introduction The terrestrial orchid genus Nervilia is diagnosed by its hysteranthous pattern of emergence but is nested among leafless myco-heterotrophic lineages in the lower Epidendroideae. Comprising ca. 80 species distributed across Af…

The effect of intentional summer flooding for mosquito control on the nitrogen dynamics of impounded Avicennia germinans mangrove forests Open
Coastal wetlands such as mangrove forests are breeding grounds for nuisance-causing insects. Rotational Impoundment Management (RIM) for mosquito control involves annual summer inundation of impounded mangrove forests with estuarine water …

Long-term periodic management of Phragmites australis maintains native brackish wetland plant communities Open
Complete eradication of invasive plants is often infeasible while in some cases ‘functional eradication’, the reduction of an invader to low levels with reduced ongoing management costs, is a sustainable option. Non-native Phragmites austr…

Reproductive responses to increased density and global change drivers in a widespread clonal wetland species, Schoenoplectus americanus Open
The expansion of many wetland species is a function of both clonal and sexual propagation. The production of ramets through clonal propagation enables plants to move and occupy space, while seeds produced by sexual reproduction enable spec…

Hybridization in the Fringed Orchids: An Analysis of Species Boundaries in the Face of Gene Flow Open
Natural hybridization between closely related species in sympatry is an evolutionary process that is common in orchids. Once seen as a threat to parent species, interspecific genetic change is increasingly viewed as a source of novel varia…

Landscape and site factors drive invasive <span><i>Phragmites</i></span> management and native plant recovery across Chesapeake Bay wetlands Open
Successful invasive plant management—where invaders are sufficiently reduced and diverse native plant communities recover—remains an elusive goal for land managers. The site‐ and landscape‐scale drivers of variable management outcomes and …

Shade and drought increase fungal contribution to partially mycoheterotrophic terrestrial orchids Goodyera pubescens and Tipularia discolor Open
Many photosynthetic plants supplement photosynthetic carbon with fungal carbon, but the mechanisms that govern dependence on mycoheterotrophic carbon are poorly understood. We used exclusion shelters to manipulate water and light availabil…

Choosing a Favorable Substrate to Cultivate Native Orchids Symbiotically: Examples Using Goodyera tesselata and Platanthera blephariglottis Open
U.S. native temperate terrestrial orchids are of horticultural and conservation interest but are considered difficult to propagate from seed due to complex ecological requirements and a variable need for a mycorrhizal fungus. Although ther…

Protocorm-Supporting Fungi Are Retained in Roots of Mature Tipularia discolor Orchids as Mycorrhizal Fungal Diversity Increases Open
Mycorrhizal fungi are critical to understanding the distribution patterns of many plants, but they are especially important for orchids. Some orchids may change the mycorrhizal fungi they use through their lives, either in response to chan…

Low‐level dissolved organic carbon subsidies drive a trophic upsurge in a boreal stream Open
Energy pathways in stream food webs are often driven by allochthonous basal resources. However, allochthonous dissolved organic carbon (DOC) is generally viewed as a minor if not insignificant basal resource because much of the DOC pool co…
