-Calaxius galapagensis, a new species, is described on the basis of two ovigerous females from coral rubble in shallow water at North Plaza off Isla Santa Cruz, Galapagos Islands. The species is compared with the eight previously described species of Calaxius Sakai & de Saint Laurent, 1989, and characterized by a strongly tridentate rostral apex, and by rows of corneous spine-like setae on pere...

A new subtribe Pseudometrioxenina Legalov, subtrib. nov. with type genus Pseudometrioxena gen. and a genus: species Metrioxena decisa Pascoe, 1885 are described. nov differs from the Metrioxenina in rostrum males long erect setae ventrally, femora always lacking tooth metatibiae almost straight males. Vladimirixena 2009 elytra longitudinal carinae. key to subtribes of tribe Metrioxenini is given.

Abstract The study of integration and modularity aims to describe the organization components that make up organisms, evolutionary, developmental functional relationships among them. Both have been studied at interspecific (evolutionary) intraspecific (phenotypic ontogenetic) levels different degrees across various clades. Although evolutionary are well-characterized birds, knowledge patterns i...

Geometric morphometry has been widely used in decapods’ studies for taxonomic needs, and eco-morphological adaptation intraspecific variations recordings. Among the 40 species of genus Hippolyte, Mediterranean endemic Hippolyte sapphica is only one with two distinct conspecific morphotypes, without intermediate forms: morph-A a long, dentate morph-B very short, toothless rostrum. Previous have ...

In this paper age determination and morphological characteristics of blacktip catfish, Plicofollis dussumieri, from Oman Sea were evaluated. A total of 132 fish specimens were collected from fishing trawlers or landings from March 2011 to July 2012, with minimum and maximum of 245 mm, 195 g and 767 mm, 5801 g, respectively. Maximum life span was 12 years for the length range of 245 – 767 mm FL,...

Paleotemperatures based on ?18O values derived from belemnites are usually “too cold” compared to other archives and paleoclimate models. This temperature bias represents a significant obstacle in paleoceanographic research. Here we show geochemical evidence that belemnite calcite fibers composed of two distinct low-Mg phases (CP1, CP2). Phase-specific situ measurement revealed systematic offse...

Summary Bark in an empty container from the USA was inspected Ningbo port, China, and a Devibursaphelenchus population detected. It processed identified as minor sp. n. The new species is characterised by lateral field with three incisures, female stylet tripartite, 13.9 (12.7-14.6) μ m long without basal thickenings, secretory-excretory pore at same level nerve ring or slightly posterior, vagi...

Conventional and diffusion tensor MR imaging studies in twins sustaining severe pediatric traumatic brain injury identified reduction in fractional anisotropy (FA) in all regions of the corpus callosum, particularly the posterior body, rostral body, and genu, relative to healthy cotwins. FA from the rostrum, genu, anterior body, posterior body, and isthmus were correlated with measures of readi...

The holotype specimen of Ancylomenes australis, new species, (Crustacea: Decapoda: Pontoniinae) from Sodwana Bay, South Africa, is described and illustrated. It is the only species of the genus reported from south east Africa. It is an associate of cerianthid anemones and has a species specific colour pattern. Closely similar to A. venustus (Bruce, 1990) it is readily distinguished from it and ...
