The genus Eumerus Meigen, 1822 (Diptera: Syrphidae) is one of the most diverse hoverfly genera in west Palaearctic Region with 140 confirmed species and 80 occurring European continent. It also highly Iberian Peninsula plus Balearic Canary Islands 43 species. Recent works on this have increased number endemic to up five. Nowadays, taxonomy, distribution biology taxonomy are still far be fully u...

Rattan cane is an important forest product with economic value. Its anatomical, physical, and biological properties vary the height. This makes it difficult to select appropriate diameter for harvesting. Understanding material of rattan different sizes enhance its utilization performance end uses. Thus, present study was performed on two species, Calamus zollingeri ornatus, at heights (bottom/m...

We evaluate hemolymph osmotic and ionic regulatory abilities and characterize a posterior gill microsomal (Na+, K+)-ATPase from the marine swimming crab, Callinectes ornatus, acclimated to 21 per thousand or 33 per thousand salinity. C. ornatus is isosmotic after acclimation to 21 per thousand but is hyposmotic at 33 per thousand salinity; hemolymph ions do not recover initial levels on acclima...

The spatial and seasonal distribution of different demographic groups of the swimming crab Callinectes ornatus was analyzed with respect to its population biology in three bays (Ubatumirim, Ubatuba, and Mar Virado) in southeastern Brazil. In each bay, monthly sampling was performed during two years along six transects, established at 5, 10, 15, and 20 m depth (parallel to the beach line), in a ...

A new species of the fish family Labridae, Suezichthys rosenblatti, is described from specimens collected at Isla San Felix, Isla Juan Fernandez and Isla San Ambrosio, off the coast of Chile. Suezichthys rosenblatti is distinct in having a combination of 11 dorsal fin soft rays and 11 anal fin soft rays. It falls in the group of species that has 1½ scale rows above the lateral line and lack a s...

We analyzed the phylogenetic relationships of the Malagasy plated lizards in the family Gerrhosauridae based on DNA sequence fragments of four mitochondrial and five nuclear genes. Various clades were strongly supported by the concatenated data set and also recovered by separate analyses of mtDNA and nucDNA. In particular, two clades here named the Z. rufipes group (containing Z. bemaraha , Z. ...

Cephalopoda were observed in situ and under laboratory conditions at Lizard Island, Great Barrier Reef, Australia. Observations on habitat, foraging and activity patterns are included. The major chromatic components and body patterns are described for Octopus cyanea, O. ornatus, Hapalochlaena spp., Metasepia pfefferi and Sepia papuensis. Components of body pattern include color, texture, postur...

An updated checklist of the genus Eumerus Meigen, 1822 is presented from Pakistan along with two new country records, i.e., vestitus Bezzi, 1912 and sogdianus Stackelberg, 1952. native to Central Southern Europe, but recorded east Asia, Afrotropical region, recently also India. Both species are collected northern areas – extreme edge western Himalayas, where a significant diversity hoverflies h...

specimens of the subfamily milesiinae (diptera: syrphidae) were collected using sweeping net from saqqez region, kordestan province located in the northwestern iran during 2012-2013. in total 25 species in 12 genera were identified. of which eumerus transcaspicus (stackelberg, 1952) is reported for first time from iran. diagnostic characters besides supplementary photos of the new record are pr...
