Fire and herbivory interact to alter ecosystems carbon cycling. In savannas, herbivores can reduce fire activity by removing grass biomass, but the size of these effects what regulates them remain uncertain. To examine grazing on fuels regimes across African we combined data from herbivore exclosure experiments with remotely sensed density. We show that, broadly substantially both herbaceous biomass activity. The was strongly associated densities, surprisingly, mostly consistent different...
ABSTRACTThe mid-Pliocene Upper Laetolil Beds at Laetoli in northern Tanzania have produced a rich diversity of fossil vertebrates, including the remains and traces early hominin, Australopithecus afarensis. The fauna from older Lower Beds, dating 3.8 Ma to than 4.3 Ma, has not previously been subject detailed analysis. This study, based on renewed palaeontological investigations, provides first systematic account fauna, along with brief synthesis geology palaeoecology. Forty species mammals...
Climate and environmental change are considered to be important drivers of hominin evolution. However, the relationships between climate at global regional scale on a local pertinent paleoecology paleobiology remain unclear. In addition change, localized geomorphological factors such as basin hydrology topography have been suggested play critical role in driving paleoenvironmental change. This study uses linear mixed models test relative impact versus local-scale variation stable carbon...
