Predator Size Structure Fails to Alter Nonconsumptive Effects in Streams. [PDF]
Ecol EvolStonefly predators caused pervasive nonconsumptive effects on benthic invertebrates in a headwater stream. These effects did not depend on stonefly size structure. Predator biomass may be the key determinant of stonefly induced nonconsumptive effects in streams.

The first mayfly (Ephemeroptera, Baetidae) from Late Cretaceous amber of North Carolina, USA [PDF]
Fossil RecordNowadays, Baetidae are among the most diverse and widespread mayfly families worldwide. However, fossil records of this family are very scarce, and each newly discovered specimen is of great importance for assessing the evolutionary history of this group.

Identification of Larvae of Australian Baetidae [PDF]
Museum Victoria Science Reports, 2011 Identification keys are provided for larvae of 57 species of Baetidae from Australia for the genera Bungona (2 spp), Centroptilum (10 spp), Cloeon (7 spp), Offadens (32 spp), Platybaetis (1 sp), and Pseudocloeon (5 spp). Species concepts were formed by using a combination of morphological characters and nuclear and mitochondrial DNA sequences.
