| ABSTRACT Campylothorax viruaensis sp. nov., a new species of paronellid springtail from the Amazon Rainforest, state of Roraima, Brazil, is herein described and illustrated. The new species is characterized by: pale yellow body with dark blue pigment on abdomen III and IV; dorsal chaetotaxy presenting S5i macrochaeta on head, mesothorax with 6-8 macrochaetae in p1-4 complex; A5 as macro or microchaeta on abdomen IV; collophore anterior side with 4+4 anterior long chaetae; and mucro with five teeth. Other characteristics usually omitted in traditional descriptions for the genus are presented such as morphology of apical region of third and fourth antennal segments, labial papillae, chaetotaxy of subcoxae, collophore, abdomen V and ventral region of head.... |

| Abstract Fourteen novel microsatellite loci are described and characterized in two species of electric eels, Electrophorus variiand E. voltaifrom floodplains and rivers of the Amazon rainforest. These loci are polymorphic, highly informative, and have the capacity to detect reliable levels of genetic diversity. Likewise, the high combined probability of paternity exclusion value and low combined probability of genetic identity value obtained demonstrate that the new set of loci displays suitability for paternity studies on electric eels. In addition, the cross-amplification of electric eel species implies that it may also be useful in the study of the closely related E. electricus, and to other Neotropical electric fishes (Gymnotiformes) species as tested... |

| Rosewood (Aniba rosaeodora Ducke, Lauraceae) is an Amazonian evergreen tree and a source of the purest linalool, the main component of its essential oil, which is very valuable in the international perfumery market. After decades of over-exploitation it is currently considered as threatened. We evaluated the genetic diversity and its distribution in four populations in Central Amazonia. Thirty-five reliable RAPD markers were generated, of which 32 were polymorphic (91.4%). Variation was higher within the populations (76.5%; p < 0.0001) and geographic distribution contributed to population differentiation (23.4%; p < 0.0001). The Amazon River had a small influence on gene flow (3.3%; p < 0.0001), but we identified evidence of gene flow across the... |
