Palaeobotanical studies from tropical Africa: relevance to the evolution of forest, woodland and savannah biomes.
Fossil plants provide data on climate, community composition and structure, all of which are relevant to the definition and recognition of biomes. Macrofossils reflect local vegetation, whereas pollen assemblages sample a larger area. The earliest solid evidence for angiosperm tropical rainforest in Africa is based primarily on Late Eocene to Late Oligocene (ca. 39-26 Myr ago) pollen assemblage...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Diatom fossils in mires: a protocol for extraction, preparation and analysis in palaeoenvironmental studies
When fossil diatoms are preserved in mires, they can be excellent indicators of ecological conditions and very useful in palaeoenviromental reconstruction, both alone and in combination with other siliceous fossils. Processing techniques for diatom frustules have varied and been modified according to the sediment from which the diatoms are being extracted. They differ from those used for palyno...
متن کاملHealth Sector Reforms -- Measures, Muddles & Mires
Public sector reforms for several decades have been premised on the assumption that improving the ability of government to manage its business will lead to improved social and economic progress.
