“…Likewise, interspeciÞc interactions in this biotope are rare or nonexistent, and this is thought to be largely a consequence of low species richness, low niche occupancy, and abundant resources (Crafford et al 1986, Crafford 1990. Such a paucity of interspeciÞc interactions is in keeping with what theory would predict for an apparently stable, though adverse environment, where abiotic constraints should be more important than biotic interactions (Southwood 1977, Greenslade 1983, Holm 1988.…”

“…For example, Connell (1975Connell ( , 1980 and Menge and Sutherland (1987) suggested that competition is most likely in moderately harsh physical environments, and Arthur (1987) argued that older communities are more likely to be structured by interspeciÞc interactions than younger ones. Likewise, Holm (1988) suggested that given sufÞcient time, and hence the accumulation of species, interspeciÞc interactions are likely to develop in stable, adverse environments.…”

“…In the previous section on ecological concepts, species functional traits were interrelated with species-habitat relationships, species distribution and abundance, and suitability criteria for preferential mesohabitat use, i.e., water depth, velocity, substrate; proximity to instream structural elements; and bank vegetative cover [113,116,[221][222][223][224][225][226]. This section expands on the review of fish trait-based concepts because of its key role for the development of multi-stage ecohydraulic-based mesohabitat classification schemes.…”

Stream restoration practice typically relies on a geomorphological design approach in which the integration of ecological criteria is limited and generally qualitative, although the most commonly stated project objective is to restore biological integrity by enhancing habitat and water quality. Restoration has achieved mixed results in terms of ecological successes and it is evident that improved methodologies for assessment and design are needed. A design approach is suggested for mesohabitat restoration based on a review and integration of fundamental processes associated with: (1) lotic ecological concepts; (2) applied geomorphic processes for mesohabitat self-maintenance; (3) multidimensional hydraulics and habitat suitability modeling; (4) species functional traits correlated with fish mesohabitat use; and (5) multi-stage ecohydraulics-based mesohabitat classification. Classification of mesohabitat units demonstrated in this article were based on fish preferences specifically linked to functional trait strategies (i.e., feeding resting, evasion, spawning, and flow refugia), recognizing that habitat preferences shift by season and flow stage. A multi-stage classification scheme developed under this premise provides the basic "building blocks" for ecological design criteria for stream restoration. The scheme was developed for Midwest US prairie streams, but the conceptual framework for mesohabitat classification and functional traits analysis can be applied to other ecoregions.

“…In this study, we define environmental stability as the degree of constancy and predictability of changes in local environmental conditions (Bruton 1989, Holm 1989. Other investigations have shown that altricial forms are typically associated with unstable or colonial environments, where competition for resources is usually less intense than in more stable environments (May 1974, Balon 1981, 1986b, Noakes & Balon 1982, Stearns 1982, Bruton 1989).…”

“…In this case, enhanced vitellogenesis in L. goodei could be associated with the precocial development of morphological characters. However, the differences in reproductive investment and morphological development may have actually been driven by fac-tors other than those associated with environmental stability (Holm 1989). Lee et al (1980) suggested that L. goodei occur predominantly in waters with extremely low dissolved oxygen concentrations.…”

SynopsisImportant differences were observed in the early ontogenies of Lucania parva and Lucania goodei. These differences can be explained in terms of the altricial-precocial model of speciation. Lucania parva can be recognized as an altricial form that produces many eggs with relatively little yolk investment, compared to the more precocial L. goodei. Many of the differences observed in embryo, larva and juvenile specimens appear to be related to these differences in gamete investment. Accelerated developmental rates in the precocial form suggest that paedomorphosis is an important proximate mechanism in the bifurcation of alternative lifehistory styles in this genus. Some morphological characteristics, such as vitelline circulation and body shape, may be transformations associated with the particular environmental conditions in which the animals must develop and survive. Our observations suggest that these two species in the genus Lucania have followed different ontogenic trajectories in response to prevailing environmental conditions.
