Extending the Network

Although our network emerged from a need to understand an extreme event that is regionally resetting major ecosystem types, the potential for DIREnet easily extends to other complementary themes and programs (Figure 5) including 1) an examination of drought as a special case of extreme events (Gutshick & BassiriRad 2003), 2) a global perspective on drought impacts (Kogan 1997), 3) the major environmental challenges suggested by the national Research Council for NEON (Tilman et al 2003), and associated work on climate change (CLIMAS), and 4) the socioeconomic implications of drought (Swetnam et al in prep).

A severe regional drought that began in the late 1990’s rapidly and dramatically altered southwestern forest and woodland ecosystems (Fig. 1). The drought became a catalyst, bringing researchers and land managers together to consider a long-term strategy to understand the drought in light of global climate change. The result of these interactions was the Drought Impacts on Regional Ecosystems Network (DIREnet). The network consists of 45 core participants from 24 institutions and coordinates studies on drought impacts on forest and woodlands of the Southwest. It also seeks to understand the role of climate change in mediating such extreme events. DIREnet will promote specific research questions and collaborations that could not be addressed without such pan-regional coordination. An example of promoting collaborations is a recent study documenting the impacts of the drought and ensuing bark-beetle outbreaks, and proposing a linkage to climate change (Breshears et al 2005). This is an important study that documents the extent (Fig. 1) and intensity (Fig. 2) of a major drought that was hotter than past droughts and may be one of the first documented global change droughts.



Figure 5. Extensions of network activities


The success of DIREnet will in large part be measured by our ability to foresee and make connections with other networks and programs. For example, how well would the proposed NEON climate domains help us document the ecological impacts of this or future droughts. Figure 6 shows that the Rocky Mountain-Colorado Plateau (Domain 13) contained the vast majority of the mortality observed in southwestern forests and woodlands. Thus, if NEON infrastructure had been dispersed across three fixed platforms and one mobile platform, it would have greatly aided our ability to understand the processes and document the patterns of the drought-related mortality across the region and over different time scales. The drought and its relationship with climate change should be used as a model in developing NEON infrastructure and determining its deployment.

The overall plan for the network is illustrated in Figure 3. The network activities include identifying research themes, targeting funding opportunities and products, developing a coordination plan that includes a powerful online research forum, and the development of education (Figure 4) and outreach efforts.

DIREnet Informatics

The Southwest Ecological Research Forum (SERF): exploring a novel informatics metaphor


  • Conventional community websites are often just passive data warehouses  hard to search, weak metadata, quickly outdated.

  • Most of scientific “action” – analysis, discussion, collaboration – happens off-line.

  • Drinking from a firehose: scientists need more help indexing, organizing, and staying aware of ongoing developments in a data-rich world.

SERF Design Goals:

  • Complete, extensible data archive for DIRENET community.

  • Interactive Community: Authentication, user-customizable tools/interfaces, access control

  • Powerful tools for online collaboration and data awareness

  • Bring not just research data, but also scientific interaction within the community online in a virtual lab space!

Key Hypotheses

1) Spatial and temporal climate variability (Comrie et al. 1998) correlate with tree mortality (Logan & Powell 2001), fire (Swetnam & Betancourt 1992) and ecosystem productivity across the region (Allen et al. 1998);

2) Northern populations of Southwest tree species will experience less drought stress and hence less selection for drought tolerance

3) Evolutionary paths will be redirected. There is evidence that extreme events such as these droughts exert the major selection pressures (Gutschick & BassiriRad 2003) and may explain diverse patterns of trait associations;

4) Drought & tree mortality will greatly alter fire regimes across the region in complex ways;

5) Consequences of the death and changing distributions of dominant trees will be community-wide (Whitham et al. 2003). For example, with over 1000 species dependent upon pinyon pine (Brown et al. 2001), drought will affect diverse taxa from microbes to vertebrates and only a coordinated network can bring the findings of such diverse taxa and disciplines together;

6) Ecosystems will be completely transformed (versus intact ecosystems moving upwards along gradients of temperature and precipitation) (Scheffer et al. 2001);

7) Invasive species will expand across the region as a result of wide-scale disturbance; and

8) The recovery phase is prolonged and may account for major effects on inclusive fitness (Gutschick & BassiriRad 2003), thus, it is imperative to follow the patterns of resource use, growth, development, and reproduction over long periods and diverse geographic locations, by coordinating research of many groups and institutions.

SERF Features:

  • Dynamic, customized interface. Users have access to differing data and operations depending on identity.

  • Secure user data uploadand sharing.

  • User curation. Users have control over their own data and records  easy editing and full control over access/sharing.

  • Powerful search mechanisms: Search across datasets; create and download “virtual datasets” drawn from such searches.

  • Data-connected discussion forums: Authorized users contribute to “discussion forums” attached to specific datasets.

  • Interconnection with Grid: Ultimate goal is to allow searches spanning datasets in SERF and other Grid sources.

  • Data Awareness: SERF users can request notification when specific kinds of datasets/data types are added to SERF.

  • E-Notebook:SERF Users can bookmark and annotate search results, data records, and other SERF contents in an online notebook.

Figure 3. Functions of the Network

Progress to date:

  • Core SERF infrastructure created and installed.

  • People, Pubs, and Labs modules complete and being populated.

  • Search and virtual result set download tools complete.

  • Several research data sets (climatology) installed.

  • Prototypes of data uploading mechanisms.
