      'My Favorites' is a special kind of lens which you can use to bookmark modules and collections directly in Connexions. 'My Favorites' can only be seen by you, and collections saved in 'My Favorites' can remember the last module you were on. You need a Connexions account to use 'My Favorites'.

      Definition of a lens

      Lenses

      A lens is a custom view of Connexions content. You can think of it as a fancy kind of list that will let you see Connexions through the eyes of organizations and people you trust.

      What is in a lens?

      Lens makers point to Connexions materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

      Who can create a lens?

      Any individual Connexions member, a community, or a respected organization.

      What are tags? tag icon

      Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

Digital Elevation Model

Module by: John Janovec

Summary: A digital elevation model of the los amigos conservation area.

Figure 1: By viewing this Digital Elevation Model (DEM), it is clear that one of the dominant factors of our study landscape is its hydrological complexity. Like arteries and veins, the complex hydrology has driven landscape change, which has in turn driven the evolution and diversification of the rich flora and fauna of the region. The Amazon Rivers Program have discovered a highly diverse aquatic fauna in the region and are testing landscape-scale hypotheses regarding the evolution and diversification of the aquatic ecosystems. Faced with a high diversity of plant species in the study area, Los Amigos Botany is still in the stage of exploration and discovery. Collections have been made in the region of the station property (red diamond), and in selected areas along the Madre de Dios (1), Los Amigos (2), Amiguillos (3), and other (4) rivers. In collaboration with Mathias Tobler, team members of the Los Amigos Botany project will intensify focus on quantitative inventory and monitoring of plant diversity built within a framework of GIS and other tools for organization, analysis, visualization, and presentation of biotic and abiotic diversity patterns (betadiversity) across the landscape. For the systematic inventory and monitoring of plant diversity, we will apply the Los Amigos GIS to design, guide, and manage an intense collection strategy that maximizes the heterogeneity of habitats sampled. We will use this type of approach to test some on-going hypotheses about the evolution and diversification of plant diversity in the study area and region.
