Lampsilis dolabraeformis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Lampsilis dolabraeformis faces severe population declines primarily due to dam construction and river channelization that have altered natural flow regimes and sediment transport patterns essential for mussel reproduction. Water quality degradation from agricultural runoff and urban development has reduced dissolved oxygen levels and increased sedimentation in critical habitat areas. The species' complex reproductive cycle, which requires specific fish hosts for larval development, makes it particularly vulnerable to disruptions in aquatic ecosystem connectivity and fish community composition.
Habitat
This freshwater mussel inhabits medium to large rivers with stable gravel and sand substrates, typically in areas with moderate to swift current flow. It requires well-oxygenated waters with low sedimentation levels and depends on specific fish species as hosts for its parasitic larval stage.
