Molecular and Serologic Detection of Ehrlichia spp. in Endangered Brazilian Wild Captive Felids

Ehrlichiosis, an emergent tickborne disease that affects both humans and animals, may represent a threat to the survival and preservation of wild felids in Brazil There are few studies of ehrlichiosis in wild felids in Brazil, but Ehrlichia spp are present in domestic cats Antibodies to Ehrlichia canis have been reported in a puma (Puma concolor) In this study we assessed the presence of these hemoparasites in the blood of Brazilian wild captive felids of the 72 animals tested, 5 (7%) were seropositive for the E cams antigen, and L1 (15%) were positive for E emirs DNA sequences We also performed sequence alignment to establish the identity of the parasite species infecting these animals using 16S rRNA and omp-1 genes Sequences based on 16S rRNA were similar to those found in dogs and cats from Thailand, Brazil, China, and Taiwan and with E canis obtained from a single individual (human) in Venezuela Ehrlichia sp sequence from sampled felines based on omp-1. gene was similar to the p28 and p30 multigene family of E canis To our knowledge, this is the first study of molecular detection of Ehrlichia sp in Brazilian wild feline species

Molecular phylogenetic and morphological analyses of Oidium heveae, a powdery mildew of rubber tree

Powdery mildew of rubber tree caused by Oidium heveae is an important disease of rubber plantations worldwide. Identification and classification of this fungus is still uncertain because there is no authoritative report of its morphology and no record of its teleomorphic stage. In this study, we compared five specimens of the rubber powdery mildew fungus collected in Malaysia, Thailand, and Brazil based on morphological and molecular characteristics. Morphological results showed that the fungus on rubber tree belongs to Oidium subgen. Pseudoidium. Nucleotide sequence analysis of the ribosomal DNA internal transcribed spacer (ITS) region and the large subunit rRNA gene (28S rDNA) were conducted to determine the relationships of the rubber powdery mildew fungus and to link this anamorphic fungus with its allied teleomorph. The results showed that the rDNA sequences of the two specimens from Malaysia were identical to a specimen from Thailand, whereas they differed by three bases from the two Brazilian isolates: one nucleotide position in the ITS2 and two positions in the 28S sequences. The ITS sequences of the two Brazilian isolates were identical to sequences of Erysiphe sp. on Quercus phillyraeoides collected in Japan, although the 28S sequences differed at one base from sequences of this fungus. Phylogenetic trees of both rDNA regions constructed by the distance and parsimony methods showed that the rubber powdery mildew fungus grouped with Erysiphe sp. on Q. phillyraeoides with 100% bootstrap support. Comparisons of the anamorph of two isolates of Erysiphe sp. from Q. phillyraeoides with the rubber mildew did not reveal any obvious differences between the two powdery mildew taxa, which suggests that O. heveae may be an anamorph of Erysiphe sp. on Q. phillyraeoides. Cross-inoculation tests are required to substantiate this conclusion. © The Mycological Society of Japan and Springer-Verlag 2005.

The history of the introduction of the giant river prawn, Macrobrachium cf. rosenbergii (Decapoda, Palaemonidae), in Brazil: new insights from molecular data

The giant river prawn, Macrobrachium cf. rosenbergii, is one of the most cultivated freshwater prawns in the world and has been introduced into more than 40 countries. In some countries, this prawn is considered an invasive species that requires close monitoring. Recent changes in the taxonomy of this species (separation of M. rosenbergii and M. dacqueti) require a re-evaluation of introduced taxa. In this work, molecular analyses were used to determine which of these two species was introduced into Brazil and to establish the geographic origin of the introduced populations that have invaded Amazonian coastal waters. The species introduced into Brazil was M. dacqueti through two introduction events involving prawns originating from Vietnam and either Bangladesh or Thailand. These origins differ from historical reports of the introductions and underline the need to confirm the origin of other exotic populations around the world. The invading populations in Amazonia require monitoring not only because the biodiversity of this region may be affected by the introduction, but also because admixture of different native haplotypes can increase the genetic variability and the likelihood of persistence of the invading species in new habitats.

A regulação da economia da inovação: patentes e biodiversidade no desenvolvimento dos países do trópico úmido

Esta dissertação apresenta uma análise da regulação da inovação em países do Trópico Úmido. A questão norteadora é como estes países lidam com a regulação da propriedade industrial nas suas políticas de inovação e como eles incorporam sua rica biodiversidade neste contexto. Propriedade intelectual – particularmente patentes – fornece uma ampla discussão nas políticas de inovação, contudo, também indicam como as questões da biodiversidade são negligenciadas pelos governos ao estabelecer seu caminho de convergência para o desenvolvimento. O estudo selecionou alguns países do Trópico Úmido que são conhecidos por seus esforços de convergência e de grande biodiversidade, são eles: Brasil, China, Cingapura, Filipinas, Índia, Indonésia, Malásia, México, Tailândia, Taiwan e Vietnã. Os dados coletados nas bases de dados de patentes da Organização Mundial da Propriedade Intelectual – OMPI mostram que esses países fazem pouco uso de patentes para a proteção da biodiversidade. O conhecimento científico sobre a riqueza de espécies e sua apropriação pela sociedade é limitada. Isso pode ocorrer quando a biodiversidade não é vista pelas instituições do Trópico Úmido como um ativo crucial. Argumenta-se que os países devem concentrar seus investimentos em P&D em ativos específicos, portanto, nós acreditamos que isso se aplica para a biodiversidade. Fazendo uma análise dos sistemas de patentes de regulamentação desses países selecionados, verificou-se que os requisitos básicos de uma patente são padronizados. Nossa análise sugere que os países do Trópico Úmido redirecionem a sua proteção da propriedade intelectual, a fim de que as inovações futuras destaquem os ativos específicos da região. Além disso, um projeto cuidadoso de leis sobre esses direitos é necessário, levando em conta os aspectos econômicos, sociais e ambientais. A divulgação das vantagens locais através da análise da intensidade da apropriação da biodiversidade por meio do sistema de patentes, bem como a comparação entre a dinâmica das leis de patentes dos países no sistema de inovação, pode orientar as decisões institucionais em relação ao desenvolvimento tecnológico regional.

Responses of transplanted native tree species to invasive alien grass removals in an abandoned cattle pasture in the Lacandon region, Mexico

We tested the early performance of 16 native early-, mid-, and late-successional tree species in response to four intensities of grass removal in an abandoned cattle pasture dominated by the introduced, invasive African grass, Cynodon plectostachyus, within the Lacandon rainforest region, southeast Mexico. The increase in grass removals significantly improved the performance of many species, especially of early-and mid-successional species, while performance of late-successional species was relatively poor and did not differ significantly among treatments. Good site preparation and at least one additional grass removal four months after seedling transplant were found to be essential; additional grass removals led to improved significantly performance of saplings in most cases. In order to evaluate the potential of transplanting tree seedlings successfully in abandoned tropical pastures, we developed a "planting risk index", combining field performance measurements and plantation cost estimations. Our results showed a great potential for establishing restoration plantings with many early-and mid-successional species. Although planting risk of late-successional species was considered high, certain species showed some possibilities of acclimation after 18 months and should be considered in future plantation arrangements in view of their long-term contributions to biodiversity maintenance and also to human welfare through delivery of ecosystem services. Conducting a planting risk analysis can help avoid failure of restoration strategies involving simultaneous planting of early-, mid-, and late-successional tree species. This in turn will improve cost-effectiveness of initial interventions in large-scale, long-term restoration programs.

Aerial organ anatomy of Smilax syphilitica (Smilacaceae)

Smilax L. in Brazil is represented by 32 taxa and it is a taxonomically difficult genus because the plants are dioecious and show wide phenotypic variation. The analysis and use of leaf anatomy characters is recognized as a frequently successful taxonomic method to distinguish between individual taxon, when floral material is absent or minute differences in flowers and foliage exist such as in Smilax. The aim of this study was to characterize the anatomical features of the aerial organs in Smilax syphilitica collected from the Atlantic Rainforest, in Santa Teresa-ES and the Smilax aff syphilitica from the Amazon Rainforest, in Manaus, Brazil. For this, a total of three samples of Smilax were collected per site. Sample leaves and stems were fixed with FAA 50, embedded in historesin, sectioned on a rotary microtome, stained and mounted in synthetic resin. Additionally, histochemical tests were performed and cuticle ornamentation was analyzed with standard scanning electron microscopy. S. syphilitica and S. aff syphilitica differed in cuticle ornamentation, epidermal cell arrangement and wall thickness, stomata type and orientation, calcium oxalate crystal type, and position of stem thorns. Leaf blades of S. syphilitica from the Amazon Rainforest have a network of rounded ridges on both sides, while in S. aff syphilitica, these ridges are parallel and the spaces between them are filled with numerous membranous platelets. Viewed from the front, the epidermal cells of S. syphilitica have sinuous walls (even more pronounced in samples from the Amazon); while in S. aff syphilitica, these cells are also sinuous but elongated in the cross-section of the blade and arranged in parallel. Stomata of S. syphilitica are paracytic, whereas in S. aff syphilitica, are both paracytic and anisocytic, and their polar axes are directed towards the mid-vein. Calcium oxalate crystals in S. syphilitica are prisms, whereas in S. aff syphilitica, crystal sand. Thorns occur in nodes and internodes in S. syphilitica but only in internodes in S. aff syphilitica. These features have proven to be of diagnostic value and may support a separation into two species, but future studies are needed to confirm that S. aff syphilitica is indeed a new taxon. Rev. Biol.
