Sand Ecosystems

We studied the Orchidaceae flora of white-sand ecosystems (campinaranas) in the Uatumã Sustainable Development Reserve, Amazonas State, Brazil. The family was represented by 60 species and 31 genera, with Maxillaria (10 spp.), Epidendrum (9 spp.) and Octomeria (6 spp.) being the most rich genera. Among the listed species, approximately 40% have a restricted distribution in the Amazonian domain, ocurring in different ecosystems. Four species, Cattleya wallisii, Maxillaria brasiliensis, Octomeria sagittata and Prosthechea vespa are known only from Brazil. Epiphytism was the most common habit, and Aldina heterophylla (Fabaceae) was the preferential phorophyte, with 67% of the total taxa occurring associated with this tree species. Taxonomic descriptions, illustrations, ecological comments, phenological information, geographical distribution and an identification key of the taxa are provided.

Two new species of Caraipa (Calophyllaceae) are described and illustrated: Caraipa glabra and C. iracemensis. Both species are known only from the municipality of Presidente Figueiredo, Amazonas state, Brazil. They both occur on patches of white-sand vegetation and they are locally abundant. Caraipa glabra is a small tree and can be distinguished from other Caraipa species by the complete absence of hairs on the leaf lamina, pedicel and fruits. Caraipa iracemensis is morphologically similar to C. grandifolia and C. caespitosa, and can be distinguished by its habit, leaves and petiole size, as well as fruit surface and size.

The Sustainable Development

Global warming has become international concern, culminating with the ratification of the Kyoto Protocol which includes definitions and objectives of the sustainable development mechanisms and features that make it easier for the industrialized countries to jointly compensate for their polluting greenhouse gas emissions. Porciúncula is a city known for its agricultural development and the lack of characterization of ecosystems associated with the Atlantic Forest biome. Facing this chaotic scenario is Nova Canaã farm located in the Ribeirão da Perdição Environmental Preservation Area its forest ecosystem provides a series of environmental services such as carbon storage and CO2 sequestration. The team of researchers from OM Consultoria Ambiental performed the quantification of the biomass (Bwood) of the bole which resulted in estimates of 398.4753 t.ha-1 corresponding to 199.2377 tC.ha-1. The estimates obtained for the forest ecosystem of the farm can be used as a reference for the establishment of forest restoration projects under the under the sustainable development mechanism established the Kyoto Protocol.

The citrus leprosis mite, Brevipalpus yothersi Baker, is not considered to cause major damage to orange trees in the Brazilian Amazonas state. However, little is known about the diversity of plant mites and about mite damage to plants in this state of northern Brazil. The objective of the present study was to evaluate the level of occurrence of the leprosis mite in this region and the diversity and prevailing population levels of associated mites in unsprayed orange groves of the surroundings of Manaus, Amazonas state. In total, 1,614 mites were collected on citrus trees (616 of eminently predatory groups, 541 of eminently phytophagous groups and 457 of other groups). On plants growing spontaneously in orange groves, 514 mites were collected (270 of eminently predatory groups, 26 of eminently phytophagous groups and 218 of other groups). Most predators collected (638 specimens) belonged to Phytoseiidae, representing 14 species. The most abundant phytoseiids were Amblyseius aerialis Muma and Iphiseiodes zuluagai Denmark & Muma. Only 197 B. yothersi were collected, on leaves of orange, Lantana camara L. and Solanum paniculatum L.. Leprosis symptoms were not observed, and this may be related to the relatively low densities of the leprosis mite. The plant species Borreria verticillata (L.), Clidenia hirta (L.), L. camara, Paspalum virgatum L. and S. paniculatum are reservoirs of two abundant predatory mites of orange trees, A. aerialis and I. zuluagai.

Central Amazon

The Amazon River Basin, one of the world’s most threatened ecosystems, has an enormous diversity of fish species, a result of temporally and spatially complex habitat containing biogeochemically different river systems. The annual hydrologic cycle results in floodplain lakes during low water and inundates forests during high water, exposing fish to different resources and environmental conditions. The two principal river systems in the central Brazilian Amazon are blackwater, with nutrient-poor acidic water, and nutrient-rich whitewater. Although species-rich, the Amazon Basin is data-poor in terms of comparative studies on a regional scale. We analyzed data sets from independent sampling studies of pelagic fish in 16 floodplain lakes, nine whitewater (Rio Solimões) and seven blackwater (Rio Negro), in the central Amazon Basin of Brazil. Our findings suggest striking similarities in pelagic fish diversity patterns. Species richness was virtually equal (165 in whitewater and 168 in blackwater). Both species richness, and number of migratory species, per lake increased toward the confluence of the rivers in both systems in our study. The proportion of unique species was also similar in whitewater lakes and blackwater (41 and 43%, respectively), boosting total regional richness to 237 species. However, species composition in whitewater lakes was more homogenous (lower β diversity), and species composition was associated with conductivity and pH in whitewater, but with dissolved oxygen and transparency in blackwater. Therefore, regional fish diversity cannot be represented by sampling one lake or even one drainage system, but must include multiple lakes from both systems. These two systems may differ in sensitivity to anthropogenic stressors such as damming and deforestation.
