Patterns of Life-History Diversification in North American Fishes: implications for Population Regulation
Interspecific patterns of fish life histories were evaluated in relation to several theoretical models of life-history evolution to explore relationships among variables and to ordinate species. Expand
Patterns of variation in life history among South American fishes in seasonal environments
The three reproductive patterns are interpreted as being adaptative with respect to relative intensity and predictability of temporal and spatial variation in abiotic environmental parameters, food availability, and predation pressure. Expand
Life history strategies, population regulation, and implications for fisheries management
Life history theories attempt to explain the evolution of organism traits as adaptations to environmental vari- ation. A model involving three primary life history strategies (endpoints on aExpand
Spatial and Temporal Variation in Tropical Fish Trophic Networks
Four lowland aquatic food webs were investigated over the course of two years, finding that extensive among—site variation in food—web parameters was associated with differences in species richness and environmental differences associated with rainfall patterns, physiography, and gross primary production. Expand
Compensatory density dependence in fish populations: importance, controversy, understanding and prognosis
This work advocates an approach to compensation that involves process-level understanding of the underlying mechanisms, life-history theory, careful analysis of field data, and matrix and individual-based modelling. Expand
Overfishing of Inland Waters
Abstract Inland waters have received only slight consideration in recent discussions of the global fisheries crisis, even though inland fisheries provide much-needed protein, jobs, and income,Expand
Ecomorphological Diversification in Lowland Freshwater Fish Assemblages from Five Biotic Regions
The analysis supports the thesis that species interactions are important determinants of community morphological features, particularly in species-rich tropical regions and interprets evidence of greater niche diversification at lower latitudes within a habitat type as being derived primarily from the influence of competition and predation. Expand
Organization in Natural Assemblages of Desert Lizards and Tropical Fishes
Techniques are developed for the analysis of community organization and bench tested on a set of simple model systems with known structure (i.e., with and without guild structure, with varyingExpand
Ontogenetic diet shifts and resource partitioning among piscivorous fishes in the Venezuelan ilanos

  • 1 November 1989
Patterns of habitat utilization indicate that piranhas may restrict diurnal use of the open-water region by other piscivores, and diffuse competition for food resources during the approximately four-month transition season probably is the principal factor yielding patterns of diet specialization. Expand
Local and regional determinants of stream fish assemblage structure: inferences based on taxonomic vs. functional groups
It is suggested that analyses using functional groups can more directly infer ecological responses to environmental variation, and therefore may provide a more fruitful avenue for developing and testing ecological theory of community organization across biogeographic scales. Expand
