Subduction fluxes through geologic time
Much of my research career has been spent working both on modern oceanic volcanic systems and at the same time looking at their Archaean counterparts. Many authors have attempted to make inferences on early Earth models based on modern processes which can be increasingly well constrained. In this short review I show how we are beginning to understand and quantify inputs to modern subduction sys...
متن کاملTrichoptera Phylogeny, Adaptations, and Biogeography Through Geologic Time
Trichoptera are a well-studied group of aquatic insects that are recognized by both entomologists and limnologists, for their especially peculiar habit of building nets and cases. The phylogeny of the order is a point of controversy with systamatists. However, the knowledge of their biogeography and their water quality and temperature tolerance provides great promise for the study of past aquat...
متن کاملNatural radioactivity in virgin and agricultural soil and its environmental implications in Sungai Petani, Kedah, Malaysia
A study on natural radioactivity in virgin and agricultural soil samples collected from Sungai Petani was conducted using high-purity germanium. The mean activity concentrations of 226Ra, 232Th, and 40K in virgin soils were 51.06±5.83, 78.44±6.42, and 125.66±7.26 Bq kg−1, respectively, while those in agricultural soils were 80.63±5.78, 116.87±7.87, and 200.66±18.24 Bq kg−1, respectively. The co...

متن کاملThe Decapoda (crustacea) as Predators on Mollusca through Geologic Time
The relationship between predator and prey is a persistent theme in marine paleontology. Herein we focus on the decapod Crustacea, the shrimps, lobsters, and crabs, and their role as predators on the Mollusca through geologic time. Five major means by which decapods crush shells or eat shelled prey might be recorded in the body-fossil record, as they require specialization of the appendages. Th...
