A black, non-troglomorphic amphibian from the karst of Slovenia: Proteus anguinus parkelj n. ssp. (Urodela: Proteidae) Naturalis
Sket, B.; Arntzen, J.W..
A morphologically distinct cavernicolous salamander Proteus anguinus from southeastern Slovenia (Bela Krajina) is described as P. a. parkelj ssp. n. It differs from P. a. anguinus in a dark pigmentation, fully developed eyes, a skull with broader and shorter bones and fewer teeth, a voluminous jaw musculature that gives the head a bulky appearance, a proportionally longer trunk with a higher number of vertebrae, shorter extremities, and a shorter tail. Most of these traits are considered to be plesiomorphic character states. An allozyme analysis over 40 loci has shown the new dark pigmented taxon to be genetically similar to a white and troglomorphic neighbouring population from Stična (DNei = 0.23). Both populations in turn are genetically dissimilar to a...

A Comparative Analysis of the Morphological Characteristics of Elite Karatekas, Judokas, Taekwondoists, Boxers and Wrestlers International Journal of Morphology
Malacko,Julijan; Doder,Dragan; Stankovic,Veroljub; Dokmanac,Milorad; Savic,Biljana; Doder,Radoslava.
The aim of this research was to use a system of 37 variables of morphological characteristics on a sample of 108 elite male athletes (25 karatekas, 27 judokas, 19 taekwondoists, 18 boxers and 19 wrestlers), aged 17 to 23, to determine any statistically significant differences between the groups of athletes in terms of variable means, so that during the training process, the selection of athletes could be carried out in a proper and objective manner and that the training transformation processes could be managed more effectively. After processing the data using the statistical method of a multivariate and univariate analysis of variance (MANOVA/ANOVA), we obtained results that indicate that among the karatekas, judokas, taekwondoists, boxers and wrestlers...

A distinctive new cloud-forest rodent (Hystricognathi: Echimyidae) from the Manu Biosphere Reserve, Peru Mastozool. neotrop.
Patterson,Bruce D.; Velazco,Paul M..
Recent surveys in Peru 's Manu National Park and Biosphere Reserve uncovered a new species of hystricognath rodent, a spiny rat (Echimyidae) with dense, soft fur. Inhabiting Andean cloud-forests at 1900 m, the new rodent belongs to a radiation of "brush-tailed tree rats" previously known only from the Amazon, Orinoco, and other lowland river drainages. Phylogenetic analysis of morphology (cranial and dental characters) unambiguously allies the new species with species of Isothrix. While the inclusion of the new taxon does not resolve the "star phylogeny" which underlies the echimyid radiation, it identifies the Andes as a possible theatre for the evolution of some soft-haired members of the group. The new species is described and a revised diagnosis of the...

A grama-tio-pedro (paspalum oteroi) no Pantanal Mato-Grossense. Infoteca-e
COMASTRI FILHO, J.A.; COSTA JUNIOR, E.M.A..
Um dos grandes desafios que os tecnicos e criadores da regiao do Pantanal Mato-Grossense tem enfrentado e a obtencao de especies forrageiras exoticas, que substituam com vantagem as especies nativas, consideradas de baixo indice de produtividade. Entretanto, esse proposito ate o momento no pode ser atendido, em funcao das dificuldades de adaptacao das especies introduzidas as condicoes de inundacao ou de extrema seca, alem da baixa fertilidade da maioria dos solos da regiao. Tais fatores tem impedido a persistencia de muitas dessas especies ou inibido a expressao de seu potencial produtivo. Devido a isso, chegou-se a conclusao de que e necessario dedicar mais estudos as especies nativas, que, em muitas situacoes, representam a opcao mais viavel na producao...

A light- and electron microscopic study of primordial germ cells in the zebra fish (Danio rerio) Biol. Res.
Deniz Koç,Nazan; Yüce,Rikap.
In sexually reproducing organisms, primordial germ cells (PGCs) give rise to the cells of the germ line, the gametes. In many animals, PGCs are set apart from somatic cells early during embryogenesis. This study explores the origin of primordial germ cells (PGCs) of the zebra fish and examines their morphology during early development (1st day-15th day). PGCs were selectively stained by the alkaline phosphatase histochemical reaction and viewed by light and electron microscopy from the time they are first detectable in the yolk sac endoderm. PGCs occurred in the subendodermal space on the syncytial periblast; differing from the surrounding endodermal cells. Later the PGCs moved to between the blastoderm and yolk sac and transferred to the dorsal mesentery...

A monographic review of the Thermosbaenacea (Crustacea: Peracarida) A study on their morphology, taxonomy, phylogeny and biogeography Naturalis
Wagner, H.P..
In addition to a taxonomic review of the whole order Thermosbaenacea, the general morphology and chaetotaxy are discussed in detail. Due to the results of cuticular staining, and through the study of specimens with SEM techniques also, corrections to earlier interpretations could be made. A chaetotaxic classification, modified after the one of Watling (1989), is presented. In the taxonomic part 34 species are recognized, belonging to seven genera (one new), four families (one new). The examination of adult material of the type species of Monodella, i.e., Monodella stygicola Ruffo, 1949, warranted the creation of Tethysbaena gen. nov., to comprise all other taxa previously included in Monodella. Transferred to Tethysbaena are: M. argentarii Stella, 1951; M....

A Morphological Study of the Suprascapular Notch in a Sample of Scapulae at the University of Kwazulu Natal International Journal of Morphology
Manikum,C; Rennie,C; Naidu,E. C. S; Azu,O. O.
The suprascapular notch (SSN) is important, as it is a risk factor in the development of suprascapular nerve entrapment syndrome. The purpose of this study is to describe the morphology of the SSN of a sample of normal scapulae in the Discipline of Clinical Anatomy, University of KwaZulu Natal. Sixty scapulae were used consisting of 37 males and 23 females (mean age 51 years). The superior transverse diameter and maximal depth of the notches were measured. Comparisons were made of the notch in relation to the maximal width and length of the scapulae, laterality and sex. The Rengachary classification method was adopted to describe the shape of the SSN. Analysis of morphological variations showed Type II- wide blunted V-shaped notch to be predominant (65%)....

A multi-gene phylogeny of Lactifluus (Basidiomycota, Russulales) translated into a new infrageneric classification of the genus Naturalis
Crop, E. de; Nuytinck, J.; Putte, K. van de; Wisitrassameewong, K.; Hackel, J.; Stubbe, D.; Hyde, K.D.; Roy, M.; Halling, R.E.; Moreau, P.-A.; Eberhardt, U.; Verbeken, A..
Infrageneric relations of the genetically diverse milkcap genus Lactifluus (Russulales, Basidiomycota) are poorly known. Currently used classification systems still largely reflect the traditional, mainly morphological, characters used for infrageneric delimitations of milkcaps. Increased sampling, combined with small-scale molecular studies, show that this genus is underexplored and in need of revision. For this study, we assembled an extensive dataset of the genus Lactifluus, comprising 80 % of all known species and 30 % of the type collections. To unravel the infrageneric relationships within this genus, we combined a multi-gene molecular phylogeny, based on nuclear ITS, LSU, RPB2 and RPB1, with a morphological study, focussing on five important...

A natural infrageneric classification for Cicer (Leguminosae, Cicereae) Naturalis
Davies, A.M.R.; Maxted, N.; Maesen, L.J.G. van der.
A comprehensive morphological survey and analysis of all taxonomically recognised wild species of Cicer L. (Leguminosae, Cicereae) is presented. The data (104 characters from 152 herbarium specimens representing 34 of the 44 recognised taxa in the genus Cicer with supplementary data for the remaining taxa taken from the literature) were analysed using multivariate statistics (cluster analysis, factor analysis and ordination techniques). The results are discussed in the context of extant classifications and the re-organisation of a novel infrageneric classification also incorporating information from published genetic data. A revised classification with 3 subgenera, 5 sections and 2 series is proposed.

A new deep-sea genus of nannastacidae (Crustacea, cumacea) from the lucky strike hydrothermal vent field (Azores triple junction, mid-atlantic ridge) ArchiMer
Corbera, J; Segonzac, Michel; Cunha, M.
A new cumacean genus and species, Thalycrocuma sarradini gen. et sp. nov., belonging to the family Nannastacidae is described from several sites of the Lucky Strike hydrothermal vent field (Mid-Atlantic Ridge, 37N, 1700 m depth). The new genus differs from others in the family by males lacking exopods on the pereopods 3 and 4 and having an antenna with a five-articulate peduncle and a short flagellum. This is the first cumacean species that could be considered, at the moment, as endemic from hydrothermal vent areas. Data on the accompanying fauna including other cumacean species (Cyclaspis longicaudata, Bathycuma brevirostre, Procampylaspis sp. and Makrokylindrus sp.) and some ecological remarks are included. A key for the currently known genera of the...

A new Morphological Classification of the Anterior Inferior Iliac Spine: Relevance in Subspine Hip Impingement International Journal of Morphology
Morales-Avalos,Rodolfo; Leyva-Villegas,Jorge I; Sánchez-Mejorada,Gabriela; Méndez-Aguirre,Omar; Galindo-Aguilar,Oscar Ulises; Quiroga-Garza,Alejandro; Villarreal-Silva,Eliud E; Vílchez-Cavazos,Félix; Galván,José R.B; Elizondo-Omaña,Rodrigo E; Guzmán-López,Santos.
Femoroacetabular impingement syndrome (FAI) is a clinical entity that has been recognized in recent years as a frequent cause of pain and the early development of hip arthrosis. Subspine hip impingement is characterized by the prominent or abnormal morphology of the anteroinferior iliac spine (AIIS), which contributes to the development of a clinical picture that is similar to FAI. The aims of this study were to propose a new morphological classification of the AIIS, to determine the prevalence of the different AIIS morphologies based on this classification and to correlate the presence of said morphologies with different gender and age groups. The sample consisted of 458 hemipelvises from individuals of known age and sex (264 men and 194 women). Each...

A new Neotropical species of Liothrips (Thysanoptera: Phlaeothripidae) associated with Ludwigia (Myrtales:Onagraceae) Rev. Soc. Entomol. Argent.
Zamar,María I.; Hernández,María C.; Soto-Rodríguez,Gerardo A.; Retana-Salazar,Axel P..
Liothrips ludwigi (Thysanoptera: Phlaeothripidae) is described and a key to differentiate it from the other four species present in Argentina is provided. This species can be distinguished by the following characters: major setae on head and pronotum slender and brown yellowish; anteromarginal setae short (14µ-21µ), and metanotum reticulated with hexagonal cells. Liothrips ludwigi feeds and reproduces on Ludwigia grandiflora (Michx.) Greuter & Burdet and L. grandiflora ssp. hexapetala (Hook. & Arn.) G.L. Nesom & Kartesz (Myrtales: Onagraceae). This is the first record of the association between Liothrips and this family of plants.

A new record of giant squid Architeuthis sp. (Cephalopoda: Oegopsida) in Brazilian waters Rev. Bras. Zool.
Martins,Rodrigo Silvestre; Perez,José Angel Alvarez.
A carcass of a giant squid Architeuthis sp. was found afloat off Southern Brazil (28°05'S, 45°35'W) on 29 August 1999. The specimen was a mature female of 116 cm mantle length and had arms incomplete and tentacles missing. The specimen was morphologically similar to those previously described for the Southwest Atlantic, but a few peculiarities were found on the shape of the fins, head and the cross-section and length of ventral arms. Spermatophores were found embedded within the skin of the left ventral arm, at around 60 cm from the mouth, and could be traced to the core of the arm, radiating nearly four centimeters from the point of entry. This was the third record of Architeuthis in Brazilian waters and the eighth in Southwest Atlantic when the specimen...

A new species of Asplenium section Thamnopteris (Aspleniaceae) from Indonesia Naturalis
Dong, S.Y.; Mujahidin; Wei, L.L.; Chao, Y.S..
A new species, Asplenium riswanii (sect. Thamnopteris), is described from Central Java and West Papua, Indonesia. It is distinct from any known species by having thick and rigid fronds, abaxially keeled midribs, broadly lanceolate scales, and distantly spaced sori. Morphologically, A. riswanii is not similar to any species from Malesia but somewhat close to A. antrophyoides from mainland Southeast Asia. Molecular data reveal it has an isolated position in the phylogeny. The micromorphology of spores and leaf epidermis of A. riswanii is also documented and a key to the species of Asplenium sect. Thamnopteris from Malesia is given.

A new species of Sipapoantha (Gentianaceae: Helieae) from northern Brazil Naturalis
Lepis, K.B.; Maas, P.J.M.; Struwe, L..
A new species from Gentianaceae (tribe Helieae) is described from northern Brazil. Sipapoantha obtusisepala sp. nov. is distinct from the previously single member of the genus, Sipapoantha ostrina, by having a woody and branched habit, sessile and ovate leaves with an acute apex, and a smaller calyx with circular lobes. Sipapoantha obtusisepala is based on somewhat incomplete material and tentatively placed in Sipapoantha based on the presence of key generic characters such as coriaceous leaves with strongly revolute margins and blue corollas. It has only been recorded from one locality in the Brazilian-Guyana border area in the state of Roraima.

A New Statistical Method for Comparative Anatomy International Journal of Morphology
Aversi-Ferreira,Tales Alexandre.
Rules, formulas and statistical tests have been widely used in studies that use continuous variables in the normal or Gaussian distribution or other tests whose data fit this type of distribution (t and z distributions) and whose parameters can be defined. However, there are cases in which the model and goal of the scientific work allow only the use of discrete or nominal variables. The absence or presence of a structure or organ (muscles, nerves, blood vessels, bones, and ligaments), characteristics associated with these organs, such as the source of nerves, vessels and muscles and the distribution of nerves and vessels are discrete and / or nominal variables that do not fit the Gaussian distribution, nor of z or t, unless the measures of these structures...
