Tales of the unexpected: phylogeography of the arctic-alpine model plant Saxifraga oppositifolia (Saxifragaceae) revisited.
Arctic-alpine biota occupy enormous areas in the Arctic and the northern hemisphere mountain ranges and have undergone major range shifts during their comparatively short history. The origins of individual arctic-alpine species remain largely unknown. In the case of the Purple saxifrage, Saxifraga oppositifolia, an important model for arctic-alpine plants, phylogeographic studies have remained ...
متن کاملRespiratory Shifts in Developing Petals of Saxifraga cernua.
Changes in the oxygen uptake of petal slices by the cytochrome and alternative respiratory pathways were monitored during petal development in the arctic herb Saxifraga cernua. As the petals developed, rates of total respiration increased to a maximum rate during petal unfolding (day 4.5), and thereafter declined. Respiration in petals of all ages was at least partially resistant to cyanide, in...
متن کاملPopulation Genetic Differentiation and Taxonomy of Three Closely Related Species of Saxifraga (Saxifragaceae) from Southern Tibet and the Hengduan Mountains
The effects of rapid, recent uplift of the Hengduan Mountains on evolution and diversification of young floristic lineages still remain unclear. Here, we investigate diversification of three closely related Saxifraga species with a distribution restricted to the Hengduan Mountains (HM) and southern Tibet, and comment on their taxonomy based on molecular evidence. Three chloroplast DNA fragments...
متن کامل“The Ex Situ Conservation of Stinking Cedar”
The propagation of plants for food, timber, medicines and aesthetics has been a principal activity of man for millennia. However, the systematic propagation of plant material for the purposes of conservation has a recent history, probably dating back only a few decades. The propagation and distribution of Torreya taxifolia from wild collected, documented material is one of the largest projects ...
متن کاملIntegrating Ex situ and In situ Conservation of Lemurs
Site-based and cross-regional habitat and species conservation e!orts in Madagascar, such as proposed in the previous chapters of this Lemur Conservation Strategy, should always be the main focus of lemur conservation. However, with many wild lemur populations rapidly declining and their habitat being lost at constantly high rates, captive assurance colonies are becoming increasingly important,...
