Fluctuating Asymmetry:Environmental causes in adult and larval tiger salamanders, <i>Ambystoma tigrinum nebulosum</i>
Foraging trade-offs along a predator-permanence gradient in subalpine wetlands
Scott A. Wissinger, Howard H. Whiteman, Grace B. Sparks, Gretchen L. Rouse, Wendy S. Brown, Foraging Trade-Offs along a Predator-Permanence Gradient in Subalpine Wetlands, Ecology, Vol. 80, No. 6 (Sep., 1999), pp. 2102-2116
Two new Harpellales living in Ephemeroptera nymphs in Colorado Rocky Mountain streams
Two new species of harpellid gut fungi (Zygomycota: Trichomycetes) are described from the hindguts of mayfly nymphs inhabiting high altitude Rocky Mountain streams: the new genus and species Legeriosimilis tricaudata living in Ameletus sp. (Siphlonuridae), and the new species Glotzia coloradense fro
Courtship behavior in a polymorphic population of the Tiger Salamander, <i>Ambystoma tigrinum nebulosum</i>
Delayed egg hatching and semivoltinism in the nearctic stonefly <i>Megarcys signata</i> (Plecoptera:Perlodidae)
Delayed egg hatching can influence the survival of aquatic insects by reducing exposure to competi- tors, predators, parasites, or unfavorable environmental conditions. We examined egg development in a Colorado population of the stonefly, Megarcys signata (Plecoptera: Perlodidae), whose larvae in- h
Rapid size-specific changes in the drift of <i>Baetis bicaudatus</i> (Ephemeroptera) caused by alterations in fish odour concentration
Criteria determining behavioural responses to multiple predators by a stream mayfly
McIntosh. A. R. and Peckarsky, B. L. 1999. Criteria determining behavioural responses to multiple predators by a stream mayfly - Oikos 85: 554-564. We investigated prey responses to multiple predators by observing drift and positioning of Buetis bicuudctrus (Ephemeroptera: Baetidae) nymphs in the pr
Three Harpellales that live in one species of aquatic chironomid larva
Two new species of harpellid gut fungi, Smittium fecundum and Stachylina robusta, were found living in larvae of Psectrocladius sp. (Diptera: Chironomidae) in a high-altitude kettle pond in the Rocky Mountains of Colorado. A third species of Harpellales, Smittium mucronatum, previously known only fr
Dispersal of the fairy shrimp <i>Branchinecta coloradensis</i> (Anostraca): Effects of hydroperiod and salamanders
The absence of fairy shrimp (Anostraca) from permanent ponds and lakes is hypothesized to be the result of vertebrate predation. However, hatching cues for anostracan diapausing eggs include factors associated with the filling of temporary pond basins, and desiccation often increases the fraction of
Dispersal and gene flow in freshwater invertebrates
Sex-specific fitness payoffs in a facultatively paedomorphic population of the tiger salamander <i>Ambystoma tigrinum nebulosum</i>
Phenotypic plasticity of a larval caddisfly along a predator-permanence gradient in subalpine wetlands
The effect of trout on the diversity, richness and abundance of the mayfly species
A manual of the common North American species of the aquatic leafmining genus Hydrellia (Diptera: Ephydridae)
Effects of size at metamorphosis on stonefly fecundity, longevity, and reproductive success
The data suggest that selection pressures determining body size at metamorphosis may operate independently on males and females, resulting in evolution of sexual size dimorphism, protandry, and mating early in the adult stage.
Head and body size relationship in polymorphic tiger salamander larvae from Colorado
Fitness and community consequences of avoiding multiple predators
This study demonstrates the importance of considering multiple predators when measuring direct sublethal effects of predators on prey fitness and indirect effects on lower trophic levels, and attributes the non-additivity of effects of fish and stoneflies on mayfly growth to an interaction modificat
Life histories and the strengths of species interactions: combining mortality, growth, and fecundity effects
Interactive effects of one species on another may simultaneously influence mortality, growth, and fecundity. To quantify the strength of an interaction between two species, we must therefore use techniques that integrate these various responses into estimates of overall effect. Demographic models of
