Stochasticity in Structural and Functional Characteristics of an Indiana Stream Fish Assemblage: A Test of Community Theory

In general, ecological assemblages and communities appear to be regulated primarily by either deterministic or stochastic processes. It is currently important to quantify the relative frequencies of these two types of assemblages since most ecological theory is applicable only to deterministic systems. We attempted to distinguish the mechanism regulating species abundances and trophic structure in an Indiana stream fish assemblage. Samples collected over a 12-yr period were separated by season…

Assemblage stability in stream fishes: A review
- Environmental Science

It is suggested that CVs are a better estimator of population/assemblage stability, than either Kendall's W or the standard deviation of the logarithms of numerical censuses and the interpretation of CV values is less ambiguous than either of the aforementioned metrics.

Results from this study suggest that turtles and fishes can be considered simultaneously and exhibit similar patterns of species distribution across the landscape, at least at local scales.
Spatiotemporal Variation in Fish Assemblage Structure in Tropical Floodplain Creeks

Biotic assemblages of aquatic floodplain systems have great potential to randomly reshuffle during annual flood periods, and have been described both as stochastically and deterministically…
Persistence of Stream Fish Assemblages: Effects of Environmental Change

It is suggested that, in the absence of detailed knowledge of home ranges of component species, an assessment of assemblage stability should be based on at least several localities within a watershed.
Temporal changes in replicated experimental stream fish assemblages: predictable or not?
- Environmental Science
- 2006
The finding that initially identicalassemblages, isolated from most external factors, would diverge in the structure of fish assemblages over time suggests a lack of strong internal, deterministic controls in the assemblaging, and that idiosyncratic or stochastic components even within habitat patches can play an important role in assemblage structure in natural systems.
Functional Organization of Stream Fish Assemblages in Relation to Hydrological Variability
- Environmental Science
- 1995
The strong hydrological—assemblage relations found in the 34 midwestern sites suggest thatHydrological factors are significant environmental variables influencing fish assemblage structure, and that hydrology alterations induced by climate change (or other anthropogenic disturbances) could modify stream fishassemblages structure in this region.

- Environmental ScienceThe American Naturalist

The test of taxocene persistence and resilience showed that this assemblage was both persistent and resilient over the course of the study, despite repeated defaunation, demonstrating that the relationship of environment to community organization is complex and dependent upon the evolutionary and ecological characteristics of the taxa examined.

It is hypothesized that increased suibstratum complexity leads to greater species richness based on several lines of evidence: different species showed different substratum preferences, colonization of mixed stubstrata generally resulted in greater mean species richness than did colonization of a single substratum type, and both species diversity and substratum complexity were greatest at the within-microhabitat level.

Regression analyses show that the number of species in any area was correlated most strongly with stream depth although an effect of position was also significant, and species diversity was independent of position and depended on depth alone.

Contemporaneous disequilibrium, a new hypothesis to explain the "paradox of the plankton".

A contemporaneous disequilibrium model to explain the diversity of the lake phytoplankton is highly plausible, because at any one time, many patches of water exist in which one species is at a competitive advantage relative to the others.
