Estimation of invertebrate biomass is a critical step in addressing many ecological ques- tions in aquatic environments. [] Key Result A total of 442 new and published regressions are presented, mostly for genus or species, based on total body length or other linear measurements. The regressions include 64 families of aquatic insects and 12 families of other invertebrate groups (mostly molluscs and crustaceans).

Length–mass relationships for adult aquatic and terrestrial invertebrates in a California watershed

The results suggest that the use of terrestrial regressions to estimate aquatic insect biomass flux in riparian habitats overestimates both the absolute magnitude of biomass flux as well as its relative importance to insect standing stocks.

Estimation of biomass from body length and width for tropical rainforest canopy invertebrates

It was concluded that the most accurate method for estimating invertebrate biomass from proxy body measurements is the use of taxon-specific regression equations, especially those that incorporate body width in the model, but equations based on body shape categories may be useful for estimating the biomass of groups for which no length-mass relationship has been determined.

Length-mass relationships of macro-invertebrates in a freshwater stream in Japan

The results show that the relationships could differ at the genus level, and careful estimates may be needed for the length-mass relationships even in the same genus if the targets have diverse ecological traits.

Length–mass relationships for transitional water benthic macroinvertebrates in Mediterranean and Black Sea ecosystems

Length-mass relationships for macroinvertebrates in freshwater environments of Patagonia (Argentina)

The equations obtained allow the estima- tion of biomass of invertebrates in Patagonian running waters from measurements of linear di- mensions, facilitating calculations of benthic standing crop and of secondary production.

Length-mass relationships in the aquatic invertebrate genera Helobdella (Hirudinea: Glossiphoniidae) and Asellus (Crustacea: Asellidae) of an Andean wetland of Colombia

The goal of this study was to find mathematical relationships between the length and biomass of two representative genera of aquatic invertebrates in the Jaboque (Engativa) wetland located in Bogota, Colombia, to facilitate estimation of the mass of individuals.

Spatial and Temporal Pattern in Length-Mass Regressions of Freshwater Gastropods in Nevada Spring Ecosystems

Length-mass regressions of gastropods showed intraspecific variation, as well as spatiotemporal variation among the same species, and published equations should be used with caution when habitat characteristics and length ranges are similar compared to those in the literature.

Length‐mass models for some common New Zealand littoral‐benthic macroinvertebrates, with a note on within‐taxon variability in parameter values among published models

Regression models are developed and presented to predict dry mass from two linear dimensions for 17 benthic macroinvertebrate taxa common to littoral zones of New Zealand lakes and there was a very high degree of variability among published length‐mass models for the family Chironomidae.

Relationships between length and weight of freshwater macroinvertebrates in Japan

The length–weight relationships obtained in this study were similar to those obtained in North America and Europe at the lowest taxonomic level, whereas they could be different from those obtained at the higher taxonomic levels.

Length-mass equations for freshwater unionid mussel assemblages: Implications for estimating ecosystem function

Biomass is often used to scale the contributions of individuals and their functional traits to a community or ecosystem. However, accurate biomass measurements can require destructive sampling, which…

Estimation of insect biomass by length and width

Estimation of insect biomass is extremely important to studies of ecosystem processes because of the great abundance of insects, their ecological and taxonomic diversity (Stork, 1988) and their importance as a vertebrate food resource (Rotenberry, 1980).

Chironomid biomass determination from larval shape

Comparison of measurements of freshly-killed chironomid larvae with measurements taken after preservation in 70% ethanol showed no change in body shape due to preservation, and length measurements from larvae preserved in this way are suitable for use in the calculation of larval biomass when the relationship to the unpreserved weight is known.

Although egg production and birth rates were highest in summer months, high death rates were responsible for the late-summer declines in density and production, which suggest heavy predation or environmental stress, or both, during summer months.

Population size, growth, and production of a unionid clam, Anodonta grandis simpsoniana, in a small, deep Boreal Forest lake in central Alberta

Production/biomass ratios were highest for clammers of 2 and 3 years of age, but the amount of biomass produced was greatest for clams of 5–8 years ofAge, and the overall production/biOMass ratio (live weight) was 0.25 and varied with annual differences in growth.

Production dynamics and resource utilization of snag-dwelling mayflies in a Blackwater river

It is suggested that a fluctuating habitat (snags), a continuously replenished food supply, high biomass turnover, and high drift densities help perpetuate a persistent, resilient, and diverse mayfly assemblage with little resource partitioning.

Distribution, Age Structure, and Movements of the Freshwater Mussel Elliptio complanata (Mollusca: Unionidae) in a Headwater Stream

Distribution of the mussels was highly clumped, but no physical, chemical, or hydrologic factors examined were significantly correlated with mussel abundance.

Trophic linkage between stream centrarchids and their crayfish prey

A trophic level energy budget was developed by enumerating food habits for different age (size) fish, estimating annual production for both fish and crayfish, and using laboratory- and literature-derived bioenergetic and gross efficiency data.

Relationships between body size and biomass of aquatic insects

P predictive equations were developed to estimate dry weight from body length measurements for forty-three taxa of aquatic insects and indicated that the relationship between biomass and body size was best expressed by a power equation, Y =aXb, rather than by linear or exponential equations.

Length-Weight Regressions in Tropical and Temperate Forest-Understory Insects

Powers of the length-weight relation W = a l b for overall and taxon-specific regressions of forest-understory insects are almost always less than 3 and frequently substantially so, a tendency that is apparently more pronounced in the tropics.
