[{"name":"norstrom-2017-mozambique-1","title":"Paleoenvironmental data from Lake Chilau, southern Mozambique, inferring savanna and lake level dynamics in the last 7700 years","summary":"This data set contains proxy data from a paleoenvironment reconstruction study covering the last 7700 years in southern Mozambique, derived from fossil sediments in Lake Chilau, located within the savanna ecosystem. The proxy records are based on assemblages of fossil phytoliths (siliceous plant remains) and diatoms (siliceous algae frustules).

The Holocene, DOI: 10.1177\/0959683617721327","comments":"These data were retreived for a study that explored temporal dynamics within grassland and Miombo woodland ecosystems and their potential coupling to hydro-climate change during the late-Holocene period (Norstr\u00f6m et al., 2017). The data describe phytolith assemblages used for interpretation of vegetation dynamics, and diatom assemblages used for lake-level variability. The Lake Chilau record suggests high abundance of Panicoideae and other mesophytic grasses during the AD 1200s and 1300s, followed by an increase in Chloridoideae and grasses of more xerophytic affinity between ca. AD 1400 and 1550. This vegetation transition takes place during the early phase of the so-called \u2018Little Ice Age\u2019 (LIA), when regional palaeoclimate records report a shift from warmer and wetter towards drier and cooler conditions in southern Africa. Concurrent to these shifts within the grassland biome, the Chilau record reports an increase in phytoliths associated with arboreal vegetation (ca. AD 1400\u20131550), probably associated with the woody component of the Miombo savanna ecosystem.","category":"Lacustrine","subcategory":"Sediment cores","keywords":"Diatoms; Phytoliths; Miombo; Savanna; Lake level; Mozambique; Africa; Palaeoclimate; Palaeoecology; Palaeohydrology","scientist":"Elin Norstr\u00f6m","firstname":"Elin","lastname":"Norstr\u00f6m","address":"Departement of Geological Sciences, Stockholm University","postalcode":"SE-106 91","city":"Stockholm ","province":"","country":"Sweden","parameters":"Earth science > Climate indicators > Paleoclimate indicators > Biological records > Paleovegetation","location":"Continent > Africa > Eastern Africa > Mozambique","progress":"Completed","language":"English","project":"Reconstruction of past hydrological change and vegetation dynamics in south-east Africa (VR-U-forsk, 348-2013-6241, PI Elin Norstr\u00f6m, Stockholm University)","publisher":"Bolin Centre Database","version":"1","constrains":"Free, but cite Norstr\u00f6m et al.
