Decrypting the Invasion of Non-native Cattails (Typha spp.) in the Fraser River Estuary, British Columbia, Using Morphological and Microsatellite Analyses

Abstract

Paper summary generated by OpenAI: This study investigates the invasion of hybrid cattail (Typha × glauca) in the Fraser River Estuary, British Columbia, using morphological and microsatellite analyses. By evaluating 46 samples identified in the field, the research confirms the accuracy of morphological identification, revealing that 100% of the field identifications were correct. The findings indicate that most hybrids are F1s, displaying heterosis in several traits, and provide the first genetic evidence of T. × glauca in British Columbia. This work enhances regional monitoring and management strategies for Typha by offering a reliable method for identifying this cryptic invasive species.
