floodplains; hurricanes; rivers; sediments; watersheds; Great Barrier Reef; Queensland
Abstract:
... The sedimentology, geomorphology and chronology of late Quaternary fluvial landforms and sedimentary sequences within the Mulgrave River catchment in northeast Queensland suggest that episodic stripping or wholesale erosion of Holocene floodplains is a major mode of sediment delivery to the Great Barrier Reef lagoon. The last major phase of Holocene valley sediment removal likely occurred sometime ...

Abstract:
... Waterholes in African savanna ecosystems are often locations of carnivore serial predation. At Ngamo Pan, located in Hwange National Park, Zimbabwe, predators take advantage of natural and artificial waterholes to ambush prey, resulting in the a vast accumulation of large mammal bones across the local landscape. Lions are presumed responsible for many predation occurrences surrounding waterhole lo ...

Measuring the abundance and size distribution of framboidal and euhedral microscopic crystals of pyrite has proven to be an effective method to determine the paleoenvironmental conditions in sedimentary rocks bearing these minerals. However, micropyrites can be found in other geological environments as well, such as low-grade metamorphic and hydrothermal. In these cases, their sizes and distributi ...

Abstract:
... Inshore reefs on Australia's Great Barrier Reef (GBR) are widely argued to be in decline, although recent reports suggest that some may be more resilient than traditionally assumed. Resolution of this debate requires long-term insights into past reef development and variability to provide context for the assessment of present reef condition. Long-term reef growth histories can preserve extended re ...

Abstract:

It started at the Julian 1–2 boundary and lasted approximately until the latest Julian or early Tuvalian. In the Tethys this is reflected by a change from limestone deposits to, first, organic rich mudstones and then to siliciclasti ...
