to depressions. The shapes of the peatland bodies are mainly determined by the configuration of the under-lying and surrounding mineral stratum; their hydrotopography is also dependent on climatic factors. Conditions may vary considerably in differ-ent parts of the same peatland. For instance, parts

An important and interesting type of semantic relation, expressed in language, ‘is the relation between the parts of things and the wholes which they comprise ’ (Winston et al. 1987:417). Relationships which are expressed either with the term part, or which by their position in a part

We examined the dispersal of larvae (glochidia) of a common unionid mussel species, Actinonaias ligamentina, which need to attach to a host fish in order to develop into juveniles, in a lowland river (Sydenham River, Ontario, Canada). Generally, the decline in the number of glochidia captured

sites within the Hudson Bay Lowland, as part of the Northern Wetland Study. Two mechanisms, one diffusive and the other episodic, were found likely to be responsible for the emissions of nitrous oxide. The annual diffusive flux ranged from-3.8 mg(N20)/m 2 in a treed bog to 7.9 mg(N20)/m 2 in an open fen

) submarine fan system. The material collected from the Polish Lowlands and its interpre-tation was subsequently compared with the data from the marginal parts of the Late Cretaceous basin. All the data derived from both boreholes and outcrops have been compiled and the correlation of trends and geological

of relic terraces and raised fields indicates that the Rio Bec Maya were sophisticated cultivators. The ancient lowland Maya have been traditionally portrayed as swidden (shifting cultivation) agriculturalists (1). The persistence of the swidden concept has inhibited field inquiry of past modes

Nitrogen (N), a most limiting nutrient, is the input required in the largest quantity for lowland rice production. The concerns on N economy and efficiency and its impact on environment have renewed interest in exploring alternative or supplementary N source for sustainable agriculture. Several
