Many East African mountains are characterized by an exceptionally high biodiversity. Here we assess the hypothesis that climatic fluctuations during the Plio-Pleistocene led to ecological fragmentation with subsequent genetic isolation and speciation in forest habitats in East Africa. Hypotheses on speciation in savannah lineages are also investigated. To do this, mitochondrial DNA sequences fr...

The Buxton-Norlim Limeworks southwest of Taung, South Africa, is renowned for the discovery of the first Australopithecus africanus fossil, the 'Taung Child'. The hominin was recovered from a distinctive pink calcrete that contains an abundance of invertebrate ichnofauna belonging to the Coprinisphaera ichnofacies. Here we describe the first fossil bee's nest, attributed to the ichnogenus Celli...

ABSTRACT The analysis of downstream changes in ancient fluvial systems can better inform depositional models for foreland-basin systems. Herein we analyze the basal deposits Early Cretaceous Cedar Mountain Formation Utah to understand variety present and develop a model Sevier foreland basin. We also evaluate long-held interpretation braided origin these document numerous examples point-bar dep...

The first international workshop From Start-up to SaaS Conglomerate: Life Cycles of Software Products, IW-LCSP 2013 was held in June 11 2013 at Potsdam, Germany. In the workshop five papers were presented with topics varying from product management in ecosystems and challenges in empirical requirements engineering research to start-up methods, incubators and accelerators. In these workshop note...

Broad-scale climate control of vegetation is widely assumed. Vegetation-climate lags are generally thought to have lasted no more than a few centuries. Here our palaeoecological study challenges this concept over glacial-interglacial timescales. Through multivariate analyses of pollen assemblages from Lake El'gygytgyn, Russian Far East and other data we show that interglacial vegetation during ...
