| Abstract Marine turtle hybridization is usually sporadic and involves reports of only a few individuals; however, Brazilian populations have high hybridization rates. Here we investigated the presence of hybrids in morphologically identified immature hawksbills (Eretmochelys imbricata) along the South Western Atlantic (SWA). We sequenced one mitochondrial (D-Loop) and three nuclear DNA (RAG1, RAG2, and CMOS) markers to better understand the patterns and characteristics of hybrids. We identified 22 hybrids (n = 270), 11 of them at the extreme South of the SWA. Uruguay had the highest hybrid frequency in the SWA (~37.5%) followed by southern Brazil with 30%. These are common areas for loggerheads (Caretta caretta) but uncommon for hawksbills, and these... |

| We evaluated qualitatively and quantitatively the community structure of aquatic insects (Ephemeroptera, Plecoptera, and Trichoptera) in 19 streams in areas of Cerrado in the Paraguay, Paraná, and São Francisco river basins. The number of genera and taxonomic composition were compared at spatial (at the hydrographic basins level) and conservation levels (more preserved and less preserved areas). The influence of spatial and environmental factors in richness and abundance was also evaluated. The geographical distribution of Grumicha, Coryphorus, and Austrotinodes was expanded. The highest Trichoptera richness was found in the São Francisco river basin (F = 5,602, p = 0,004) and a higher number of Ephemeroptera genera occurred in the relatively less... |

| Cross-amplification was tested and variability in microsatellite primers (designed for Neotropical parrots) compared, in five macaw species, viz., three endangered blue macaws (Cyanopsitta spixii [extinct in the wild], Anodorhynchus leari [endangered] and Anodorhynchus hyacinthinus [vulnerable]), and two unthreatened red macaws (Ara chloropterus and Ara macao). Among the primers tested, 84.6% successfully amplified products in C. spixii, 83.3% in A. leari, 76.4% in A. hyacinthinus, 78.6% in A. chloropterus and 71.4% in A. macao. The mean expected heterozygosity estimated for each species, and based on loci analyzed in all the five, ranged from 0.33 (A. hyacinthinus) to 0.85 (A. macao). As expected, the results revealed lower levels of genetic variability... |

| Abstract Myrteae is the largest and most diverse tribe within Myrtaceae and represents the majority of its diversity in the Neotropics. Members of Myrteae hold ecological importance in tropical biomes for the provision of food sources for many animal species. Thus, due to its several roles, a growing interest has been addressed to this group. In this study, we report the sequencing and de novo assembly of the complete chloroplast (cp) genomes of six Myrteae species: Eugenia brasiliensis, E. pyriformis, E. nitida, Myrcianthes pungens, Plinia edulis and Psidium cattleianum. We characterized genome structure, gene content, and identified SSRs to detect variation within Neotropical Myrteae. The six newly sequenced plastomes exhibit a typical quadripartite... |

| Emas National Park is a very importam Conservation Unit in the Cerrado Biome. Nevertheless the fauna of this region is still poorly known. In this study, a revised list of the mammal fauna of the Emas National Park with comments about the composition and the number of species surveyed is presented. Eighty six species of mammals were recorded in the Park and neighboring area, including several rare and threatened species, like the bush dog (Speothos venaticus (Lund, 1842)), Marsh deer (Blastocerus dichotomus (Illiger, 1815)) and others. The giant rat (Kunsia tomentosus (Lichtenstein, 1830)) was recorded for the first time in a conservation unit. On the other hand, species usually very common in the Cerrado biome, don't occur in Emas National Park: the... |

| The standard length of 7610 specimens of 43 species from eight streams of rio Tibagi basin was obtained in order to analyze the means of fish sizes. The higher mean size was observed in Gymnotus carapo Linnaeus, 1758 (165,5 mm) and the smaller, in Phalloceros caudimaculatus (Hensel, 1868) (16,25 mm). Some fish like Acestrorhynchus lacustris (Reinhardt, 1874), Leporinus obtusidens (Valenciennes, 1836), Gymnotus carapo Linneus, 1758 and Synbranchus marmoratus Bloch, 1795 can reach big or medium size when adults but were collected only young, evidencing they use some streams in beginning of life. The mean size of total species was 49,81mm, what shows the small size composition of fishes in the streams. The Kolmogov-Smirnov test comparing the mean size of all... |

| ABSTRACT Due to the important ecological role of Nymphalidae as consumers of fermented fruits, excrement, exudates of decomposed plants and animals, as well as bioindicators of environmental quality that attract the interest of the general public, this study aimed to characterize the fauna of frugivorous butterflies at the Serra Azul State Park - PESA (Mato Grosso, Brazil) with regards to composition, taxonomic richness and spatial distribution. Collections were carried out in 2014 from six 250 m plots in a RAPELD module (5x5 km). We defined five sampling points in each plot and placed a Van Someren-Rydon trap (VSR), with a bait made from banana fermented in cane juice, positioned 1 m above the ground for 24 hours. We collected 204 specimens of Nymphalidae... |

| Ce rapport fait état d'une étude réalisée au laboratoire de Génétique et Pathologie de l'IFREMER dans le cadre de l'analyse d'épisodes de mortalité anormale survenue en écloserie privée de crevettes pénéides. Plusieurs hypothèses ont été avancées. La présence de Vibrio harveyi a amené à constituer une collection de 40 souches à partir desquelles une identification bactériologique a été effectuée. Elle montre en effet une dominance de souches appartenant à un groupe homogène de Vibrio harveyi. La technique de ribotypage (digestion d'ADN génomique, transfert de Southem-blot et hybridation avec une sonde spécifique) est alors mise en place. Plusieurs difficultés techniques ont ralenti l'analyse et n'ont donc pas permis d'avoir des résultats assez avancés pour... |

| This study evaluated the bee community and their associated melliferous plants in the northern region of the state of Santa Catarina, Brazil in order to ascertain the diversity and floral interactions of the local Apidae. Twelve samplings were conducted (April 2006 to March 2007) in transects, where nets were used to capture bees directly from their flowers. Voucher specimens for both bees and plants were deposited at UNIVILLE. Diversity and equitability indexes were calculated. Our sampling effort resulted in a total of 934 bees in 72 genera and five families. Forty-four plant species belonging to 19 families were visited. A dominant family in Southern Brazil, Asteraceae, was visited most often (50% of the taxa). Nearly 20% of the plants were visited by... |

| To assess the status of coral formations dominated by Acropora palmata (APF) and A. cervicornis (ACF) in the Tayrona National Natural Park (TNNP), Colombian Contribución No. 855 del Instituto de Investigaciones Marinas y Costeras – INVEMAR Caribbean, a study was conducted at the bays of Chengue, Gayraca, Nenguange and Cinto between May- December 2001. The distribution and extension of the formations in the study area were evaluated by swimming along the coast and using draft maps, a GPS and a calibrated flow-meter, and their living cover were estimated in quadrat-belt transects (1x10 m). Atotal of 29 APF (119320 m2) and 12 ACF (21760 m2) were assessed. Almost all the APF exhibited living colonies of A. palmata, but the mean cover by this species reached... |
