Sentence examples for biotic structure from inspiring English sources

The sediment biotic structure seems largely dependent on detritus-based chains, and has a high degree of spatial variability.

This gives an indication of which are the most important environmental variables implicated in the (correlative) 'explanation' of the biotic structure.

At the same time, extreme flood events may have important long-term selective and genetic consequences (e.g. Pujolar et al. 2011) given the potentially long-lasting alternations to the physical and biotic structure of the stream rearing environment.

Several lists of criteria have been formulated to discriminate between abiotic and biotic structures [21 23].

The biotic structuring factor has never before been investigated from a very small scale-perspective.

The impact of these pathways on arthropod diversity is mediated by the three ecological determinants of the populations that constitute a community: (i) abiotic conditions of the environment (including non-trophic use of biotic structures), (ii) trophic resource availability and (iii) predation (Chase & Leibold, 2003).

Classifications were derived for aquatic macrophytes, macroinvertebrates, freshwater fish and frogs using community-level modelling, or GDM, which relates the biotic assemblage structure with environmental variables.

These materials, in turn, are used to document multiple aspects of an organism's biology (green circles), including elements of genotypic and phenotypic variation as well as interspecific relationships such as parasite-pathogen dynamics, co-evolutionary relationships, and biotic community structure.

It occurs as a result of environmental variation in abiotic factors and/or biotic factors structuring the spatial distribution of populations.

Landscapes are composed of distinct, bounded units that are differentiated by biotic and abiotic structure and composition.

Soil ecosystem shifts are abrupt changes that occur at "tipping points" and have long-lasting effects on the landscape and both the biotic and abiotic structure of the soil.
