Going With the Flow? Relative Importance of Riverine Hydrologic Connectivity Versus Tidal Influence for Spatial Structure of Genetic Diversity and Relatedness in a Foundational Submersed Aquatic Plant

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
We assessed genotypic and genetic diversity in the submersed aquatic plant species Vallisneria americana in the Potomac River, USA, to understand how riverine hydrologic connectivity and tidal regime affected spatial genetic structure. We found striking differences in the structure of diversity, clonal growth, and relatedness in different tidal ...

Wild Bee Assemblages and Pollination Networks of Managed Emergent Wetlands in Central New York, USA

open access: yesEcology and Evolution, Volume 15, Issue 2, February 2025.
Wetlands are underrepresented in wild bee surveys yet we find they host a diversity of bee species and offer important late‐season floral resources. Wetland restoration and management for wildlife in the northeastern United States creates a matrix of freshwater wetland habitat that helps support the landscape's wild bee fauna.
