New Rb-Sr mineral ages temporally link plume events with accretion at the margin of Gondwana.
Read more of: New Rb-Sr mineral ages temporally link plume events with accretion at the margin of Gondwana.Five of six Rb-Sr muscovite mineral isochron ages from the Scotia Metamorphic Complex of the South Orkney Islands, West Antarctica, average 190 ± 4 Ma. The muscovite ages are interpreted […]

How useful are the recommended counts and indices in the systematics of the Octopodidae (Mollusca: Cephalopoda)
Read more of: How useful are the recommended counts and indices in the systematics of the Octopodidae (Mollusca: Cephalopoda)A morphological dataset based on 14 standard counts and indices was constructed for 68 specimens comprising 12 species of octopuses. This was used to construct distance matrices based on morphological […]

Parasite treatment affects maternal investment in sons
Read more of: Parasite treatment affects maternal investment in sonsParasitism can be a major constraint on host condition and an important selective force. Theoretical and empirical evidence shows that maternal condition affects relative investment in sons and daughters; however, […]

Cold hardening processes in the Antarctic springtail, Cryptopygus antarcticus: clues from a microarray.
Read more of: Cold hardening processes in the Antarctic springtail, Cryptopygus antarcticus: clues from a microarray.The physiology of the Antarctic microarthropod, Cryptopygus antarcticus, has been well studied, particularly with regard to its ability to withstand low winter temperatures. However, the molecular mechanisms underlying this phenomenon […]
