1. Predicting the effects of warming and species loss on ecosystems are two significant challenges currently facing ecologists. However, little is known of the interactive effects of these two factors. […]
The composition of saprotrophic fungal communities on sessile oak (Quercus petraea) and sycamore (Acer pseudoplatanus) leaf litters from a woodland at Cefnpennar in South Wales, UK, were analysed in late […]
The use of complexity-based approaches may help to advance our understanding of Earth as a system.
The study of animal foraging behaviour is of practical ecological importance1, and exemplifies the wider scientific problem of optimizing search strategies2. Lévy flights are random walks, the step lengths of […]
As marine turtles traverse entire ocean basins, a number of techniques have been developed to gather information on their movements at sea. These range from basic methods, such as mark […]
This study examined divergence in the foraging distribution, at-sea behaviour and provisioning strategies of a small procellarid, the Cook’s petrel Pterodroma cookii, during chick-rearing at 2 islands off New Zealand, […]
1. A wide range of instrumentation has been deployed on albatrosses and petrels at Bird Island, South Georgia, in studies dating back to the mid-1980s. Early results indicated the huge […]
Whilst we have now a good understanding how past glaciation influenced species at the northern hemisphere, our knowledge of patterns and modes of speciation is far more limited for the […]
Ice cores are a widely used archive to reconstruct past changes of the climate system. This is done by measuring the concentration of substances in the ice and in the […]
During the Middle Pliocene, the Earth experienced greater global warmth compared with today, coupled with higher atmospheric CO2 concentrations. To determine the extent to which the Middle Pliocene can be […]
A statistical comparison of the latitude of the open/closed magnetic field line boundary (OCB) as estimated from the three far ultraviolet (FUV) detectors onboard the IMAGE spacecraft (the Wideband Imaging […]
