Cenozoic plant macrofossil sites ofTasmania [PDF]

open access: yesPapers and proceedings of the Royal Society of Tasmania, 2002
Tasmania has an outstanding Cenozoic plant fossil record, including several sites of international significance. This paper provides a compendium of macrofossil sites and associated literature. Macrofossils (leaves, fruit, flowers, wood) are known from 59 sites, ranging from Early Eocene to Late Pleistocene in age. Most are Palaeogene to early Neogene,

The coming and going of a marl lake: multi-indicator palaeolimnology reveals abrupt ecological change and alternative views of reference conditions

open access: yesFrontiers in Ecology and Evolution, 2015
Eutrophication is the most pressing threat to highly calcareous (marl) lakes in Europe. Despite their unique chemistry and biology, comprehensive studies into their unimpacted conditions and eutrophication responses are underrepresented in conservation ...
