The article discusses sex, death, and deception in evolutionary processes. An example is given of the tongue orchid which secretes a chemical that mimics the pheromones of a female wasps causing the male wasps to land on the flower. The male wasp rubs against a pollen packet which it transfers...

Extreme weather events are expected to increase in frequency and magnitude due to climate change. Their effects on vegetation are widely unknown. Here, experimental grassland and heath communities in Central Europe were exposed either to a simulated single drought or to a prolonged heavy...

In May of 2011, an enteroaggregative Escherichia coli O104:H4 strain that had acquired a Shiga toxin 2-converting phage caused a large outbreak of bloody diarrhea in Europe which was notable for its high prevalence of hemolytic uremic syndrome cases. Several studies have described the genomic...

Biomass burning is an integral part of the Earth system, influencing and being influenced by global climate conditions, vegetation cover and human activity. Fire has long been associated with certain vegetation types and land uses in Southeast Asia, but has increasingly affected forests in...

Predicting future ecosystems changes is necessary for better managing human resources. Such forecasting requires robust vegetation models which have been tested versus observed field data. Nowadays, it is very common that a simulation model is firstly validated using modern observed data and...
- Holocene vegetation change in the mediterranean-type climate regions of Australia. Dodson, J.R. // Holocene;Nov2001, Vol. 11 Issue 6, p673
In Australia mediterranean-type climates occur in southwestern Australia and in near coastal South Australia and adjacent western Victoria. These regions support species-rich sclerophyllous heaths and shrublands with the biodiversity particularly high in the southwest. Palynological records show...
- The history of mediterranean-type environments: climate, culture and landscape. Roberts, N.; Meadows, M.E.; Dodson, J.R. // Holocene;Nov2001, Vol. 11 Issue 6, p631
This editorial introduction highlights four of the principal themes in late-Quaternary research on summer-dry, mediterranean-type environments: first, issues of historical biogeography, such as convergent evolution; second, the synchroneity of past climate change between and within different...

The sensitivity of global and regional climate to changes in vegetation density is investigated using a coupled biosphere-atmosphere model. The magnitude of the vegetation changes and their spatial distribution are based on natural decadal variability of the normalized difference vegetation...
