Feeding spectrum of a dominant splash zone enchytraeid, Mesenchytraeus bungei Michaelsen, 1901 (Annelida: Oligochaeta), in Lake Baikal (East Siberia) [PDF]
The first data on feeding spectrum of Baikal enchytraeids are given. Previously we found that Mesenchytraeus bungei Michaelsen, 1901 dominates in abundance in splash zone Oligochaeta community of Bolshie Koty Bay, Lake Baikal.

Invertebrate biomechanics [PDF]
Invertebrate biomechanics focuses on mechanical analyses of non-vertebrate animals, which at root is no different in aim and technique from vertebrate biomechanics, or for that matter the biomechanics of plants and fungi. But invertebrates are special - they are fabulously diverse in form, habitat, and ecology and manage this without the use of hard ...

Zoology: Invertebrates that Parasitize Invertebrates [PDF]
The genome of an orthonectid, a group of highly modified parasitic invertebrates, is drastically reduced and compact, yet it shows the bilaterian gene toolkit. Phylogenetic analyses place the enigmatic orthonectids within Spiralia, although their exact placement remains uncertain.

Deterrent activities in the crude lipophilic fractions of Antarctic benthic organisms: chemical defences against keystone predators [PDF]
Generalist predation constitutes a driving force for the evolution of chemical defences. In the Antarctic benthos, asteroids and omnivore amphipods are keystone opportunistic predators.
