ABSTRACT Chironomidae, so‐called non‐biting midges, are considered key bioindicators of aquatic ecosystem variability. Data derived from morphologically identifying their chitinous remains in sediments document chironomid larvae assemblages, which are studied to reconstruct ecosystem changes over time.

Relative impacts of morphological alteration to shorelines and eutrophication on littoral macroinvertebrates in Mediterranean lakes [PDF]
Development of effective methods for assessing the ecological status of lakes based on littoral benthic fauna has been hampered by the lack of quantitative data on the relative impacts of key pressures on the benthic community.

ABSTRACT Aim Changing biodiversity and environmental conditions may allow multi‐host pathogens to spread among host species and affect prevalence. There are several widely acknowledged theories about mechanisms that may influence variation in pathogen prevalence, including the controversially debated dilution effect and abundance‐occupancy relationship

Worldwide Generic Key to Pupae of Ceratopogonidae This is the first attempt at keying pupae of all known genera of Ceratopogonidae of the world. Generally, regional keys are more useful for identification but the material I examined was seriously limited and often included reared species representing genera which were otherwise unknown within a ...
