Aedeagus morphology as a discriminant marker in two closely related Cactophilic species of Drosophila (Diptera; Drosophilidae) in South America Anais da ABC (AABC)
Franco,Fernando F.; Prado,Pedro R.R.; Sene,Fábio M.; Costa,Luciano F.; Manfrin,Maura H..
Drosophila serido and D. antonietae are sibling species belonging to the Drosophila buzzatii cluster. Morphologically, they can only be discriminated by quantitative traits. In this paper we analyze the length and equalized average curvature of four regions of the aedeagus of D. antonietae and D. serido. Specimens of D. serido and D. antonietae were classified correctly 96.74% of the time. Based only on the variable that most contributed to the discrimination of the groups (equalized average curvature of the arch IV of the aedeagus), we observed significant intraspecific morphological divergence in D. serido in relation to the D. antonietae, in agreement with other markers. The high morphological divergence in equalized average curvature of the arch IV of...

Biological aspects of Autoplusia egena (Guenée) (Lepidoptera: Noctuidae, Plusiinae) Neotropical Entomology
Specht,Alexandre; Vogt,Tatiane G.; Corseuil,Elio.
Autoplusia egena (Guenée) is a moth distributed throughout the Western hemisphere. The larvae have already been found feeding on several different plant families, including important crops such soybeans and beans. To contribute to the knowledge of its biology in laboratory conditions, and considering the duration and the morphometry of each development stage, a laboratorial rearing was accomplished at 25 ± 1°C, 70 ± 10% RH and 14h photophase. The larvae were fed with black bean leaves and the adults were fed with a honey solution at 10%. The results, expressed by the mean (± SE), for the periods of each stage were: egg 3.0 ± 0.00 d; larva 15.7 ± 1.25 d; pre-pupa 1.9 ± 0.05 d; pupa 8.8 ± 0.09 d and adult: longevity 12.1 ± 0.95 d, pre-oviposition 5.4 ± 0.50...

Bruguiera (Rhizophoraceae) in the Indo-West Pacific: a morphometric assessment of hybridization within single-flowered taxa Naturalis
Duke, N.C.; Ge, X.-J..
The first putative hybrid tree species of the genus Bruguiera (Rhizophoraceae), B. × rhynchopetala, is reported from mangrove forests of China and Australia. It was described from China previously as a variety of B. sexangula. The hybrid is acknowledged as B. gymnorhiza × B. sexangula with parent species restricted to different parts of the Indo-West Pacific. The hybrid is recognised at north-eastern and south-eastern parts of the overlap area between parent distributions, but it appears absent in western parts. Further local assessments are needed across the range. Hybrid status is supported by: 1) intermediate and shared morphological characters; 2) distribution limited to areas of co-occurrence of B. gymnorhiza and B. sexangula; and 3) molecular...

Morphological variation in a secondary contact between divergent lineages of brown trout (Salmo trutta) from the Iberian Peninsula Genet. Mol. Biol.
Hermida,Miguel; San Miguel,Eduardo; Bouza,Carmen; Castro,Jaime; Martínez,Paulino.
The aim of this study was to analyze the morphological variation of brown trout (Salmo trutta) in the Duero basin, an Atlantic river basin in the Iberian Peninsula, where a spatial segregation of two divergent lineages was previously reported, based on isozyme, microsatellite and mtDNA data. In these studies, two divergent pure regions (Pisuerga and Lower-course) and several hybrid populations between them were identified. Morphological variation was evaluated in 11 populations representative of the genetic differentiation previously observed in the Duero basin, using multivariate analysis on 12 morphometric and 4 meristic traits. A large differentiation between populations was observed (interpopulation component of variance: 41.8%), similar to that...

Tanisaki,Maurício; Ogawa,Koichi; Lapa,Rita de Cássia Ribeiro da Silva; da Silva,Marcelo Cavenaghi Pereira; Watanabe,Ii-sei.
The characteristics of Calomys callosus major palatine nerve were studied employing light, transmission and high resolution scanning electron microscopy methods. For light microscopy, the specimens were fixed in Bouin's fixative solution, processed routinely and the sections were stained with hematoxylin­eosin and Azo-Carmin to identify nerve fibers. For high resolution scanning electron microscopy the O-D-O method reported by <a href="#13">Tanaka (1989)</a> was used to examine nerve fiber components and to measure the myelin sheath. Thin sections were examined by transmission electron microscopy to show axoplasmic elements and adjacent structures. The results revealed nerve fiber bundles in the lamina propria of Calomys callosus palatine...

Morphometrical Analysis of the Effect of Nicotine Administration on Brain's Prefrontal Region in Male Rat International Journal of Morphology
Jalili,C; Salahshoor,M. R; Khademi,F; Jalili,P; Roshankhah,S. H.
Nicotine is the most important alkaloid compound in tobacco. One of the major effects of nicotine is stimulation of mesocorticolimbic system. Prefrontal cortex plays a pivotal role in personality and mental state. It is considered the main cause of addiction as it is located in mesocorticolimbic dopamine system. Twenty four male rats were divided into four groups based on nicotine administration dose (0, 0.5, 1 and 1.5 g/kg). After animals were anesthetized, their brains were fixed using transcardiac method. Tissue processing and Golgi staining were performed and the stained tissue sections were analyzed by optic microscope and Motic software. By increasing the dose, nicotine significantly decreased the number of neuronal processes. In the higher dose,...

The taxonomic status of Myotis levis levis and Myotis levis dinellii (Mammalia: Chiroptera: Vespertilionidae) Rev. Bras. Zool.
Miranda,João M. D.; Bernardi,Itiberê P.; Sponchiado,Jonas; Passos,Fernando C..
Investigating the Myotis levis complex is important for understanding the taxonomic status of the two subspecies currently recognized in it: Myotis levis levis (I. Geoffroy, 1824) and M. levis dinellii Thomas, 1902. Both M. levis levis and M. levis dinellii have been recently observed in sympatry in Argentina. This finding suggests that these populations might in fact correspond to distinct species rather than subspecies, as they have traditionally been designated. By using a multivariate morphometric approach, we demonstrate that M. l. levis has secondary sexual dimorphism in several measurements, with females being larger than males; sexual dimorphism was not detected in M. levis dinellii. However, we found morphometric differences between the two taxa....

Use of Morphometric Variables for Differentiating Spanish Hound Breeds International Journal of Morphology
González,A; Luque,M; Rodero,E; González,C; Aguilera,R; Jiménez,J; Sepúlveda,N; Bravo,S; Herrera,M.
The term Podencos refers to a group of dog breeds from Spain and classification in Group 5 of dog breeds by the Fédération Cynologique Internationale (FCI). The aim of this study was to compare traits morphometric breeds of Podencos; Canario, Ibecenco, Andaluz (small, medium and large) and Orito. Ten morphometric variables were measured in 385 animals (245 females and 140 males), head length, muzzle length, height at withers, rump height, body length, head width, rump width, chest depth, chest girth and the shin circumference. Morphostructural variables were more homogeneous in the Podenco Ibicenco and the Podengo Canario, because for many years there were gradually distinctive trait standards for each breed. The discriminate analysis indicated...

Worker morphology of the ant Gnamptogenys striatula Mayr (Formicidae, Ectatomminae) in different landscapes from the Atlantic Forest domain Rev. Bras. entomol.
Oliveira,Roseli F.; Silva,Rogério R.; Souza-Campana,Débora R.; Nakano,Márcia A.; Morini,Maria Santina C..
Morphological traits, such as size and shape, may reflect a combination of ecological and evolutionary responses by organisms. Ants have been used to evaluate the relationship between the environment and species coexistence and morphology. In the present study, we analyzed the morphology of workers of Gnamptogenys striatula Mayr in different landscapes from the Atlantic Domain in southeastern Brazil, focusing on the variation in the morphological attributes of these populations compared to those from a dense ombrophilous forest. Eighteen morphological traits of functional importance for interactions between workers and the environment were measured to characterize the size and shape of the workers. In general, the results show that ants of urban areas...
