The structure of diversity in a chironomid community inhabiting submerged macrophytes was analysed, including the relationship between predation/competition and chironomid diversity. Diversity as expressed by the Shannon functionH′ was found to be strongly associated with equitabilityJ but not with species richnessS in this community. Chironomid species richness was correlated with the abundance of diatoms. DiversityH′ and equitabilityJ were significantly correlated with chironomid density… 

Dietary overlap and coexistence of chironomid larvae in a detritus-based stream

Of the seven orders of macroinvertebrates that make up the DuffinCreek riffle community, the Chironomidae were the dominant taxonmaking up, numerically, 25.8–53.7% of the total fauna. Cricotopus sp.,

The role of pH in structuring communities of maine wetland macrophytes and chironomid larvae (Diptera)

An examination of individual chironomid taxa by stepwise multiple regression showed that distribution of most taxa was controlled by water chemistry variables and macrophyte habit (i.e., floating, submergent), suggesting that competitive dominance of a few taxas was responsible for lower richness in low pH wetlands, whereas competition was weaker in high pH wetlands.

Littoral chironomids of a large Alpine lake: spatial variation and variables supporting diversity

Chironomidae are a major group of littoral secondary producers whose spatial changes in assemblage structures are shaped by diverse variables. Using their subfossil remains, we aimed at disentangling



Population dynamics, life histories and species richness in an epiphytic chironomid community.

The chironomid fauna on the spiked water-milfoil Myriophyllum spicatum was studied quantitatively for a year in a small lowland stream in eastern England and it was revealed that a significantly higher number of species than expected coexisted in April and May.

A review of the biology of British Naididae (Oligochaeta) with emphasis on the lotic environment

Naidids live in a wide range of aquatic habitats but are particularly important numerically as part of the benthic fauna of rivers with stony substrates and the response of naidid species to different kinds of pollution is varied.

Resource utilization, overlap and temporal community dynamics: a null model analysis of an epiphytic chironomid community.

The results indicate that competition is not an important factor in the temporal organization of the epiphytic chironomid community and the relationship between overlap and resource availability was discussed in a wider context.

Population ecology of the commensal chironomid Epoicocladius flavens on its mayfly host Ephemera danica

Enhanced chance of survival, rather than the supply of detrital food particles which collect on the host's body, is considered as an important benefit to accrue to E. flavens from this commensalism.

Plant Species Diversity in a Marine Intertidal Community: Importance of Herbivore Food Preference and Algal Competitive Abilities

Predators or herbivores do not simply increase or decrease species diversity of their food, but can potentially do both and the results may apply to most generalized consumers and provide a framework within which previously confusing results can be understood.

On the feeding habits of Thienemannimyia festiva (Diptera: Chironomidae)

Feeding habits of a little‐known tanypod, Thienemannimyia festiva (Diptera: Chironomidae) were analysed using samples collected from Lough Neagh, Northern Ireland, finding significant differences in diet were observed between the fourth and the third instar predators.

Grazing interactions between pulmonate snails and epiphytic algae and bacteria

The effects of grazing by Lymnaca peregra and Planorbis planorbis on Ceratophyllum demersum epiphyton and the possible mutual benefits which algae and snails may derive from coexistence were investigated under simulated natural conditions.

Density—body size allometry does not exist in a chironomid community on Myriophyllum

There is some difficulty in extending the logic of the density-body size allometry to many invertebrate communities, where body size is a strongly time-dependent, variable trait.

An assessment of biological interactions in an epilithic stream community using time-lapse cinematography

In situ time-lapse cinematography was used to record and enumerate behavioral interactions between members of an epilithic insect community in a small Michigan (U.S.A.)trout stream and interactions between simuliid larvae were less likely to lead to emigration than were interactions between blackflies and other groups.

There is no simple relationship between diversity and stability in ecological systems, and an alternate perspective for interpreting population stability is suggested.
