Caridina biyiga sp. nov. is described from Leichhardt Springs, Kakadu National Park, Northern Territory, Australia, based on morphological and molecular data. The new species is highly distinctive among its congeners in having the dactylus of pereiop

Pacific island stream communities are species-poor because of the effects of extreme geographic isolation on colonization rates of taxa common to continental regions. The effects of such low species richness on stream ecosystem function are not well

The mechanical behaviour of the Nb reinforcement (250 μm thick foils) in Nb5Si3/Nb/Nb5Si3 laminates were investigated under a variety of stress states and test temperatures. Tests were conducted at room temperature (298 K) and 77K on as-received Nb

The systematic relationships of the freshwater shrimp family, Kakaducarididae, were examined using mitochondrial and nuclear DNA sequences. Combined nuclear (18S rDNA, 28S rDNA, Histone) and mitochondrial (16S rDNA) analyses placed the kakaducaridid

The freshwater shrimp family Kakaducarididae Bruce, 1993 is revised and its familial status reappraised using morphological characters and the results of a complementary molecular study (Page et al. 2008). Based on combined morphological–molecular

Mechanical alloying(MA) and Reactive Sintering(RS) techniques were successfully used to produce Nb5Si3. Model laminates of mechanically alloyed Nb5Si3 and commercially pure niobium were prepared via vacuum hot pressing. Tensile properties for the as-

The freshwater shrimp Macrobrachium australiense is distributed throughout the majority of inland, north-west, north-east and eastern drainages. Owing to the large amount of morphological divergence, both between and within catchments, this species h
