Water Ecology
Published in Frank R. Spellman, Handbook of Water and Wastewater Treatment Plant Operations, 2020
Modern ecology has its early roots in plant geography (i.e., plant ecology, which developed earlier than animal ecology) and natural history. The early plant geographers (ecologists) included Carl Ludwig Willdenow (1765–1812) and Friedrich Alexander von Humboldt (1769–1859). Willdenow was one of the first phytogeographers; he was also a mentor to von Humboldt. Willdenow, for whom the perennial vine Willdenow’s spikemoss (Selaginella willdenowii) is named, developed the notion, among many others, that plant distribution patterns changed over time. Von Humboldt, considered by many to be the father of ecology, further developed many of Willdenow’s notions, including the notion that barriers to plant dispersion were not absolute (Smith, 2007).
Igneous intrusives in the Greater Sydney Region
Published in P.J.N. Pells, Engineering Geology of the Sydney Region, 2018
The only data on the on-shore dykes in the Greater Sydney Region which is known to roe but has been excluded from this compilation are: five long dykes marked in diagrammatic form by David (1896, Plate 1) which he extended to foci on Port Jackson between Musone Point and Double Bay; these can be interpreted to correspond to several actual dykes listed by others.an unpublished ‘field’ map of the NE of the Greater Sydney Region which was made by K.R.Sharp when a student (Pers. Comm. 21/8/75); a photocopy of this map is possessed by several geologists and organisations. Many of the dykes were taken from Willan’s (1925) map; some curiously shaped lineaments Been on aerial photographs are also marked as dykes.3 manuscript maps made by Lloyd (c.1950) which are collations of the data on the maps of Waterhouse (1902), Pittman (1903) and Willan (1925).a small scale map included in the thesis by Bell (1966, Plan 1)and which contains a few dykes selected from published maps.several small ‘popular’ publications on the natural history of the Sydney area which contain an outline of the geology and usually mention the dyke at Long Reef Point (MV 443649).
Geoscience in the Flinders Ranges: papers in support of World Heritage Nomination
Published in Australian Journal of Earth Sciences, 2020
The rock formations of the Flinders Ranges of northern South Australia have fascinated humankind since the first arrival of the indigenous people to the region tens of thousands of years ago. The appeal of the ranges is no different today, with thousands of tourists drawn to the area each year to view the panorama, walk the trails and become one with the environment, commonly with nightly campfire discussions including the day’s geological observations. In a region where nature offers many interrelated dimensions of natural history, including geology, mineralogy, geomorphology, soil science, botany, zoology, ecology and climatology, the geology underpins most of these. The geology, and the resulting scenery, are the outstanding highlight of the Flinders Ranges.
