| ABSTRACT Interspecific hybridization has several consequences for parental species, from blurring species limits to the emergence of new taxa. Petunia axillaris and P. exserta occur in sympatry in southernmost Brazil and naturally hybridize despite their different pollination syndromes and habitat requirements. We employed genetic and morphological analyses to characterize two contact zones between the species with the aim of determining the effect of interspecific hybridization. Microsatellite loci and a morphometric evaluation of the corolla shape were used to classify individuals based on their origin as pure parental or hybrids. Corolla color was used to classify individuals a priori (white, red or intermediate, for P. axillaris, P. exserta or hybrid,... |

| The epididymal region of the domestic duck is composed by efferent ductules, whose histotopology was characterized by the proximal and distal ductules and sequentially by the epididymal duct. The epithelial lining of the efferent ductules was ciliated pseudostratified and formed by columnar cells. Also the ducts epididymidis epithelium was pseudostratified but non-ciliated. Concerning the histomorphometric analysis, the epithelial height mean was significantly greater in the distal efferent ductules, differing from the lower epithelium height mean observed in proximal efferent ductules and epididymal duct. The maximum and minimum diameter mean were significantly greater in the proximal efferent ductules, comparatively to the same diameter means of the... |

| ABSTRACT: South America has numerous Criollo horse breeding farms; however, information on foal hoof growth is still limited and identifying the ideal periods to apply corrective trimming is a frequent concern for horse owners. In the present study, a morphometric analysis of hoof growth was performed on 46 Criollo foals from birth to weaning (0-8 months). Results showed that hoof growth rate was higher in the first four months followed by a decrease until the eighth month. Average growth rate of the hoof was 0.21cm per month, whereas that of the heel was 0.14cm per month. However, no significant differences were observed between medial and lateral heel length or between limbs. Coronary band perimeter and solar width showed an average increase of 0.97cm... |

| Previous studies have shown that food amount influence fish otolith structure, opacity and shape and that diet composition has an effect on otolith chemical composition. This study investigated the potential correlation between diet and otolith shape in 5 wild marine fish species by addressing 4 complementary questions. First, is there a global relationship between diet and otolith shape? Second, which prey categories are involved in this relationship? Third, what are the respective contributions of food quantity and relative composition to diet–otolith shape co-variation? Fourth, is diet energetic composition related to otolith shape? For each species, we investigated how otolith shape varies with diet. These questions were tackled by describing diet in... |

| Striped red mullet Mullus surmuletus L. 1758 is an economically important species in the Mediterranean Sea and in the northern Atlantic Ocean, where it is exploited from the Bay of Biscay to the southern North Sea (ICES, 2010). In Atlantic waters, there are two main areas where this species is caught, the Bay of Biscay and the eastern English Channel. This species was initially exploited by the Spanish fleets along the Spanish coast inside the Bay of Biscay. Originally considered as valuable by-catch (Marchal, 2008), the growing exploitation ofM. surmuletus and a conspicuous increase in landings in the English Channel and the southern North Sea by French, English and Dutch fleets have been observed from the 1990s onwards. This was attributed to an increase... |

| Exposure to physical or psychological stress causes brain damage ranging from minimal behavioural alterations to different neurodegeneration degrees implying the overproduction of oxidative-nitrosative compounds, apoptosis and cell proliferation. In the present investigation, we have analysed the effect of the chronic stress by immobilisation applied to pregnant rats over the forebrain development of the embryos. The morphometric analyses showed an accelerated evagination of the telencephalic vesicles in 12 days old fetus from stressed mothers. The forebrain perimeter and the thickness showed significative differences in relation to age-matched controls. This stress effect seemed reversible during subsequent gestational stages. This is the first work... |

| The objective of this study was to report the distinctive anatomical and histological features of the trachea of the Arabian Oryx (Oryx leucoryx). The number of tracheal rings and tracheal length were measured. The diameter, thickness and cross sectional area of tracheal ring were determined at four tracheal regions (cranial cervical (CCR), middle cervical, thoracic inlets and intra thoracic). Tracheal rings were also collected for histological analysis. The mean length of the trachea was 54.1cm ± 0.73, while the number of tracheal rings varied from 50-51. Tracheal ring measurements (diameter, thickness and cross sectional area) were smallest at the thoracic inlet region. The ratio of the outer transverse to outer vertical and inner transverse to inner... |

| Se determinó la variación espacio-temporal de la biomasa de los grupos morfo-funcionales de macroalgas y su relación con las variables ambientales: temperatura, salinidad, oxígeno disuelto y precipitaciones en dos localidades (laguna y playa) de pastizales al Norte de Ciego de Ávila desde marzo de 2010 a febrero de 2011. Las colectas se realizaron utilizando marco cuadrado de 25 cm de lado y se tomaron 15 unidades de muestreo en cada sitio. Se determinaron cinco grupos morfo- funcionales: foliosas y globosas, coriáceas, filamentosas, corticadas y calcáreas articuladas, presentando variaciones espacio- temporales los dos últimos. La laguna tuvo menor diversidad algal (13 géneros) y mayor biomasa total determinado por el aporte de las calcáreas... |

| A partir de análisis morfométricos se determinó la relación existente entre los escudos dorsales con el largo recto del caparazón (LRC) para 44 ejemplares de tortuga carey (Eretmochelys imbricata), provenientes de los dos sitios de capturas tradicionales en Cuba (Nuevitas y Cocodrilo) que operaron hasta el 2008. Se tomaron dos mediciones por escudos, ancho del escudo (AE) y largo del escudo hasta la línea de imbricación (LI) para los cuatro escudos del lado izquierdo (c1-c4) y los cinco vertebrales (v1-v5). Se encontró una relación estadísticamente significativa para todos los escudos medidos tanto en la relación (LRC-AE) como (LRC-LI), p < 0,05, resultando estas moderadamente fuertes. Las correlaciones positivas entre los escudos y los largos rectos... |

| Com o objetivo de estudar a variabilidade genética intra-específica em Oncidium varicosum Lindl. (Orchidaceae - Oncidiinae), foram avaliadas cinco populações de Minas Gerais, coletadas em Alfenas (AL), Estiva (ES), Pedra do Coração (PC), Pedra Branca (PB) e Pouso Alegre (PA). Foram considerados 22 caracteres florais, medidos a partir de "vouchers" (fichas florais), empregando-se métodos estatísticos univariados e multivariados (análise discriminante canônica - CDA e análise de agrupamento a partir de distância de Mahalanobis). Houve diferença significativa (p < 0,05) entre populações, pelo teste F, para 13 caracteres. O primeiro eixo canônico separou a população PA de PB e de PC. Os indivíduos de PA são menores que os de PC, que são menores que os de... |
