Patterns of reproductive ontogeny in four species coral reef wrasses (F: Labridae) Hemigymnus melapterus, fasciatus, Cheilinus fasciatus and Oxycheilinus digramma were investigated. Populations each sampled from two island groups the central Great Barrier Reef (GBR), Australia, reefs Philippines. These three sampling locations span 30° latitude. The GBR Philippine experience biologically signif...

Morphological changes in the reared rock bream, Oplegnathus fasciatus, from hatching to six days after hatching were examined during the early growth stage under starvation. All the larvae died within five days when feeding was delayed for three days after hatching. These results imply that initial larval food should be supplied within two days of hatching. Changes in the pectoral angle and the...

Many studies have been conducted on the fine structure of the "9 + 2" microtubules from cilia and flagella . The techniques used include both thin sectioning of whole cilia or flagella and negative staining of isolated microtubules . In this study, cilia from four diverse species of ciliate protozoa : Euplotes eurystomus, Spirostomum ambiguum, Tetrahymena pyriformes, and Colpoda ; and sperm fro...

Eight genera and 21 species of the tribe Anisoscelini (Coreidae, Coreinae) are recorded in Argentina: Anisoscelis foliaceus (Fabricius); Coribergia declivicollis (Berg); Dalmatomammurius vandoesburgi (Brailovsky); Holymenia hystrio (Fabricius); Leptoglossus chilensis (Spinola); L. cinctus (Herrich-Schaeffer); L. concolor Walker; L. crassicornis (Dallas); L. dentatus Berg; L. fasciatus (Westwood...

The first reliably identified Trechini beetle species from Baltic amber, Trechus balticus sp. n., is described. This new fossil species is most similar to extant species of the Palaearctic Trechus sensu stricto, as well as to the Nearctic Microtrechus Jeannel, 1927. Since the fossil specimen is a female and some important character states cannot be investigated, its true systematic position wit...

We assessed the fish assemblage structure and composition of Nova Ponte Reservoir (Araguari River, Upper Paraná Basin, Brazil). We observed significant differences in abundance (p = 0.0003), richness (p = 0.0005) and diversity (p = 0.02) between lacustrine and riverine zones of the reservoir. Nine species were significantly more abundant in the riverine region: Astyanax altiparanae, Astyanax gr...

Panus natarajanus sp. nov. from the Western Ghats of Karnataka, India, is described, illustrated and discussed along with P. velutinus, P. tephroleucus, P. ciliatus, P. hookerianus, Lentinus fasciatus, L. concentricus, and L. megacystidiatus. Lentinus alpacus is re-allocated to Panus as P. alpacus comb. nov., and contrasted with P. parvus. A short description with illustrations is provided of L...

The bamboo-feeding species of tribe Evacanthini are reviewed. They include 9 genera and 13 species: Angustella leucostriata Li & Wang, 1991, Boundarus nigronotus Zhang, Zhang & Wei, 2010a, Carinata kelloggii (Baker, 1923), C. nigrofasciata Li & Wang, 1994a, Convexana fleura Chen, Yang & Li, 2012, Evacanthus repexus Distant, 1908, Onukia guttata Li & Wang, 1991, O. nigra Li & Wang, 1991, Parapyt...
