Palaeoecology A breath of fresh air
Nature, 1999We owe our oxygen-rich atmosphere to the photosynthetic activity of ancient bacteria. Chemical traces found in rocks have pushed back the origins of this process to 2.5 billion years ago.

Palaeoecological background: Neotropics
Climatic Change, 1991Strong changes of temperature and rainfall effected tropical South America during the last few millions of years; the sequence of the last glacialinterglacial cycle is relatively well known. Humid and cooler climates occurred in the period between >50 000 and approx. 25 000/30 000 B.P. A cold and very dry climate occurred in the period of approx.

Palaeoecology of the Graptoloidea
Earth-Science Reviews, 2012Abstract Graptoloids (Class Graptolithina) were colonial pterobranch hemichordates and formed a major component of the early Paleozoic macrozooplankton. By analogy with modern pterobranchs, they filtered food particles from the water mass in which they lived by means of ciliated lophophores.

The palaeoecology of trilobites
Journal of Zoology, 2014AbstractTrilobites comprise a major group of extinct marine arthropods, which thrived in a variety of habitats surrounding the Palaeozoic palaeocontinents. The evidence that can be used to infer their ecology is reviewed, including functional anatomy, field occurrence and geology in comparison with living arthropods and palaeogeography. Where different

Aerobiologia, 1992
Aerobiology involves the study of particles present in the air. Of these, palaeoecologists are most interested in pollen and spores, specially those which come to rest on the surface of the ground. Pollen sampling in palaeoecological studies, therefore, uses a pollen trap which is placed at ground level and the sampling period is a whole season or year.

Beachcombing and palaeoecology
Geology Today, 2011Beachcombing is not just a diversion for the idle; it can provide unique data for the observant geologist. The perspicacious palaeontologist may find informative specimens either in pebbles or in unusual Recent shells that provide analogues of, for example, ancient organisms or interactions between extinct species.

Geology Today, 2007
With increasing interest in climate change and other issues associated with the history of the environment and anthropogenic evolution there is an ongoing requirement to investigate the Earth's natural systems. A key approach is for scientists to look back into geological time, perhaps millions of years, to see how the world has reacted to natural ...
