Promotion of collection importance is paramount in securing a future in research and outreach through the exposure of diverse stakeholders to the incredible resource of biological collections. One outlet to increase exposure to collections’ data is through data aggregation. Data aggregation allows for a wide array of research, education and outreach activities that would otherwise be impossible. As the National Resource for Advancing Digitization of Biodiversity Collections (ADBC) funded by the National Science Foundation - iDigBio has made large contributions to collections with regards to communication, outreach and community training. Two facets of iDigBio’s mission statement are: to facilitate the aggregation of collections data and to promote its use. Recently, a new resource for fish collections (fishfindR.net) has contributed to both the aforementioned missions. FishFindR utilizes data aggregated by iDigBio to explore, share and compare fish collection data as it is presented in the iDigBio portal via a web resource. The data is shown in accessible, easy to use and easy to read interfaces. This resource also provides the fish research community with a way to reconcile collection data to institutions from the iDigBio recordsets. This gives fish collections stakeholders data and tools that will be useful in communicating their value, advocating for support, applying best practices to their data publishing and improving collections’ sustainability as a community. Going forward, it is the hope that this resource will provide other taxonomic disciplines with a framework to provide similar services for their stakeholders and that through a network of taxonomic specific collection resources that collections’ staff will become similarly empowered to use their own data as a communication tool.

<em>Abstract.</em>—We reexamined a local population of Guadalupe Bass <em>Micropterus treculii </em>after cessation of a stocking program that significantly reduced the number of individuals that were hybridized with Smallmouth Bass <em>M. dolomie</em> u. Analysis of five years of post-stocking fish collection data show that the percentage of hybrids has increased in all four study sections of the upper Guadalupe River since stocking stopped. We found that hybridization had increased from 0.0% to 9.9% in Johnson Creek, 19.8% to 28.8% in North Fork Guadalupe River, 5.6% to 12.0% in South Fork Guadalupe River, and 24.2% to 26.5% in Guadalupe River main stem sections. This represents an average increase of 6.8% for all streams combined (range = 2.2–9.9%) from the last year of stocking. We also examined hybridization levels in individual stream fragments created by instream barriers (<em>n </em>= 76) to assess spatial variability along tributary and main stem corridors. Although hybridization appears to be increasing on a stream-wide basis, finer scale analysis show that hybrid distribution was spatially complex and there was a substantial portion of the study area with little or no hybridization. There were gradients of decreasing hybridization in an upstream direction in each of the tributaries and marked break points upstream of which hybridization was considerably lower (<10%). We also found that hybridization was highly variable among individual stream fragments (range 0%–71.4%) including those immediately adjacent to one another. These findings suggest that instream barriers may restrict genetic mixing throughout the system and contribute to partial isolation of populations within stream fragments. As such, further targeted intervention efforts are likely necessary to further reduce hybridization in fragments that still contain high proportions of hybrids. The patchy distribution that we observed may be a critical component to consider in assessment and restoration efforts; not only for Guadalupe Bass but also in other endemic black basses threatened by hybridization.

Wireless sensor networks are often deployed in open or even hostile environment, its security problem is very prominent, Data aggregation is easily to be attacked for security during the specific implementation process. In order to reduce the transmission of redundant data and enhance security, this article proposed a secure data aggregation and authentication scheme, .data was gathered according to the mode code, collection data was transmitted in encrypted form which will be selected nodes, ensured the confidentiality of the data; A session key was generated and delaied aggregation and authentication by using counter, ensured the integrity , authenticity and freshness of data during the transmission .The security analysis showed that the program had higher security which resisted the attack initiativly, node compromise attack and select forwarding attack and other malicious behaviors.
