Los sistemas tradicionales en las zonas productoras de café (Coffea arabica) se desarrollan ecosistemas bajo sombra, con amplia diversidad especies flora y fauna. En la actualidad, composición florística original ha modificado por cambios el establecimiento Inga spp. Por lo anterior, surge importancia conocer estructura arbórea actual del sistema agroforestal cultivo Soconusco, Chiapas. Para ta...

The distribution of macroinvertebrate communities from 5 sampling sites of the Tajan River were used to examine the relationship among physiochemical parameters with macroinvertebrate communities and also to assess ecological classification system as a tool for the management and conservation purposes. The amount of variation explained in macroinvertebrate taxa composition is within values r...

Biodiversity plays a crucial role in stability and productivity of natural ecosystem. The main goal of this research was to classify ecological groups in steppe rangeland and investigate their relationships with plant diversity indices. Therefore, fifty different Land Unit Tracts (LUT) were identified in Khod-Neuk basin, Yazd province, Iran, in 2010. Vegetation and soil samples were taken in th...

Tropical forests are major repositories of biodiversity, but are fast disappearing as land is converted to agriculture. Decision-makers need to know which of the remaining forests to prioritize for conservation, but the only spatial information on forest biodiversity has, until recently, come from a sparse network of ground-based plots. Here we explore whether airborne hyperspectral imagery can...

The feeding diversity of macroinvertebrates from the estuary of Mondego was estimated with Shannon–Wiener complementary evenness following the methodology presented in Gamito and Furtado (2009. Ecological Indicators, 9: 1009-1019). Results were compared with those from BAT (Benthic Assessment Tool; Teixeira et al., 2009. Marine Pollution Bulletin, 58: 1477-1786) applied to the same data set, ob...

The arbuscular mycorrhizal (AM) fungal distributions in the rhizosphere of 20 medicinal plants species in Zhangzhou, southeast China, were studied. The results showed 66 species of 8 genera of AM fungi were identified, of which 38 belonged to Glomus, 12 to Acaulospora, 9 to Scutellospora, 2 to Gigaspora, 2 to Funneliformis, 1 to Septoglomus, 1 to Rhizophagus, and 1 to Archaeospora. Glomus was t...

he Norbert Wiener Centenary Congress was held at Michigan State University, November 27–December 3, 1994. The Congress was cosponsored by the American Mathematical Society, the International Association of Cybernetics, and the World Organization of Systems and Cybernetics. The aim of the Congress was to reveal the depth and strong coherence of thought that runs through Wiener’s legacy and to ex...

forests are biologically diverse systems, representing some of the richest biological areas on earth. they offer a variety of habitats for plants, animals and micro-organisms. however, forest biodiversity is increasingly threatened as a result of deforestation, fragmentation, climate change and other stressors. biodiversity is the variation of life forms within a given ecosystem, biome, or on t...
