Intermediate disturbance in a late-successional hemlock-northern hardwood forest
1 An old-growth mesic forest in northern Michigan, USA, experienced an unusually intense storm in July 2002. Permanent inventory plots and a 2.9-ha mapped stand allow comparison of effects of this rare disturbance with patterns of ‘baseline’ mortality. 2 Tree mortality attributable to immediate effects of the storm was of similar magnitude to mortality over the previous decade, amounting to abo...
متن کاملSpatial and temporal variations in leaf area index, specific leaf area and leaf nitrogen of two co-occurring savanna tree species.
Foliage growth, mass- and area-based leaf nitrogen concentrations (Nm and N a) and specific leaf area (SLA) were surveyed during a complete vegetation cycle for two co-occurring savanna tree species: Crossopteryx febrifuga (Afzel. ex G. Don) Benth. and Cussonia arborea A. Rich. The study was conducted in the natural reserve of Lamto, Ivory Coast, on isolated and clumped trees. Leaf flush occurr...
متن کاملStudy of spatial and temporal rain and drought patterns in the south of Iran using TRMM
Droughts are one of the most damaging climatic phenomena, and the most complex natural hazard which affects the economy, agriculture, public health and environment in large areas. The aim of this study is to compare drought indicators derived from tropical rainfall measuring mission (TRMM) data in the south of Iran. Also the TRMM rainfall was considered, so as to investigate changes in the rai...
متن کاملSpatial and Temporal Variation in Calcium and Aluminum in Northern Hardwood Forest Floors
Acid rain results in losses of exchangeable base cations from soils, but the mechanism of base cation displacement from the forest floor is not clear, and has been hypothesized to involve mobilization of aluminum from the mineral soil. We attempted to test the hypothesis that losses of calcium from the forest floor were balanced by increases in Al in New Hampshire northern hardwoods. We measure...
متن کاملSpatial and temporal distribution of larvae of coral reef fishes in northern Red Sea, Egypt
The larval community of coral reef fishes in the Red Sea was studied in coastal and offshore sites to determine the effects of the exposure to waves and currents and the distance from the shore in structuring the larval fish community. Plankton sampling from inshore and offshore sites and the exposed and sheltered sides of the reefs resulted in the collection of 2048 larvae representing 49 diff...
