Morpho butterflies are universally admired for their iridescent blue coloration, which is due to nanostructured wing scales. We performed a comparative study on the coloration of 16 Morpho species, investigating the morphological, spectral and spatial scattering properties of the differently organized wing scales. In numerous previous studies, the bright blue Morpho coloration has been fully at...

dunaliella is a green halotolerant microalga, which has several industrial applications e.g. β-carotene production. identification of different dunaliella species has been carried out by morpho-physiological and recently molecular studies. to achieve an improved understanding of taxonomy, these studies are required to be in linkage. the present study describes molecular and specific morpho-phys...

Abstract We analyzed two morpho-species, Astyanax aeneus and caballeroi , coexisting in Lake Catemaco, with ecological differences previously associated different trophic niches. While A. is a widely distributed species, endemic to Catemaco. Due the contrasting morphology between these sympatric they were originally assigned genera, but little known about their genetic differentiation. hypothes...

The use of planktonic foraminifera in paleoceanography requires taxonomic consistency and precise assessment of the species biogeography. Yet, ribosomal small subunit (SSUr) DNA analyses have revealed that most of the modern morpho-species of planktonic foraminifera are composed of a complex of several distinct genetic types that may correspond to cryptic or pseudo-cryptic species. These geneti...

The Morpho butterflies exhibit surprisingly brilliant blue wings originating from the submicron structure created on scales of the wing. It shows extraordinarily uniform color with respect to the observation direction which cannot be explained using a simple multilayer interference model. We have performed microscopic, optical and theoretical investigations on the wings of four Morpho species a...

Molecular phylogenetic analyses of 18S rDNA (SSU) gene sequences confirm the placement of Crusticorallina gen. nov. in Corallinoideae, the first nongeniculate genus in an otherwise geniculate subfamily. Crusticorallina is distinguished from all other coralline genera by the following suite of morpho-anatomical characters: (i) sunken, uniporate gametangial and bi/tetrasporangial conceptacles, (i...

Rapid phenotypic evolution is observed in response to rapid environmental changes. These variations can occur at different scales, from the population community. We intended characterize these multiscale responses rodents archaeological site El Harhoura 2 (Rabat, Morocco), dated Late Pleistocene Holocene, and relate them paleoenvironmental variations. Upper lower first molars were used as proxi...

An abundant female population of a criconematid species identified as Mesocriconema kirjanovae (Andr ssy, 1962) Loof &De Grisse, 1989 is reported from a natural habitat in southeastern Spain. Measurements and morpho-anatomy obtained with light microscopy and scanning electron microscopy are included and compared with previous data on this species.

Four paddy fields in Guilan province in the north of Iran seasonally were sampled from April 2008 to January 2009. Twenty-two morphospecies belonging to three families of the heterocystous blue-green algae were identified. Fourteen species and one variety of these taxa are new record for Iran. Among the families Nostocaceae with six genera and 16 species showed the highest species richness.
