Abstract

Premise of research. Sixty percent of the vegetation in the alpine and subalpine region of Victoria, Australia, is endemic, making this region of prime importance for biodiversity and landscape conservation. Persistence of species under climate change may depend on genetic adaptation to changing environmental conditions, which in turn can be affected by patterns of gene flow and genetic variation for adaptive traits. Methodology. Carex hebes and Carex breviculmis are two sedge species commonly found across the Bogong High Plains of the Victorian alpine region. Carex hebes is common but restricted to alpine and subalpine areas, whereas C. breviculmis has a broader distribution. We used micros..
