  Citation × Citation Citation Abstract Copy Title: How sweet is the land? Modeling caloric landscapes for tropical hummingbirds Author: Birkett, Christina Nozomi Pollination is a critical ecosystem function for sustaining biodiversity. However, pollinators and the services they provide are threatened by landscape-altering anthropogenic activities across the globe. Habitat loss and fragmentation, introduction of invasive species, chemical use, and urbanization have been shown to impact pollination. Pollinator foraging behavior is thought to be largely a function of available floral rewards, therefore, understanding the role of resource distributions in pollinator abundance and behavior within disturbed landscapes is a key piece of information for conservation. Fine scale information on floral resource distribution across disturbed landscapes is lacking in most systems. Here we demonstrate how existing presence-only species distribution modeling techniques (i.e., Maximum entropy modeling [MaxEnt]) can be combined with widely available environmental information to create resource landscapes for both pollinator communities and specific pollinators of interest. This model is the first of its kind, making possible simultaneous visualization of fine-scale resource configuration and quantity across abroad spatial extent. We tested this method to build caloric landscapes using tropical hummingbird-plant system in Costa Rica. We found that our MaxEnt models performed well on independent data for all 13 flower species we examined. Our landscape-scale caloric map showed that available calories within each 35m² pixel ranged from 0 to greater than 30,000 across our study region. Our model provides the possibility of predicting pollinator movement and abundance based upon resource supply. As its parameters are flexible, it is broad in its potential applications. The flexibility in calibration to desired resource landscapes permits applying the model to other pollinator-plant systems. We hope that this model will complement the current ecologist’s toolbox, aiding in ensuring the continuation and health of pollinator systems. Title: How sweet is the land?

  Citation × Citation Citation Abstract Copy Title: Comparing Himalayan blackberry (Rubus armeniacus) management techniques in upland prairie communities of the W.L. Finley National Wildlife Refuge Author: Ensley, Jona L. Dedicated to the preservation and promotion of many of the nation’s most threatened and endangered species, the W.L. Finley National Wildlife Refuge is highly invested in the management of some of the last remaining upland prairies once prevalent throughout Oregon's Willamette Valley. More than a century of land fragmentation, fire suppression, and cultivation has shifted species composition and physical structure of the native prairies toward woodland ecosystems, reducing habitat quality and quantity. This transition is greatly driven by the encroachment and introduction of the non-native, woody invader Himalayan blackberry (Rubus armeniacus). This study focused on the three most common Himalayan blackberry management techniques used within the refuge's upland prairies: late summer mowing, late summer burning, and a combination of both. The goal was to analyze the efficacy of each technique in meeting the refuge objectives of controlling Himalayan blackberry populations and promoting native prairie physiognomy after one application using a complete random block design. Findings were presented to refuge managers to facilitate improved management of these fragile communities. Mowing was found to have the greatest reduction in blackberry stem and plant density and resulted in the lowest resprout density post-treatment. This treatment also met the refuge objectives of reducing woody cover and increasing graminoid cover, but did little to increase herbaceous cover when compared to the control group. Burning produced no significant increase in herbaceous cover or reduction in woody cover and provided favorable conditions for Himalayan blackberry seedling germination, contributing to a larger blackberry problem in years to come. In promoting herbaceous habitat for upland-dependent species, mowing with subsequent burning was the most successful technique. Though not as effective in reducing blackberry vigor as mowing alone, this treatment showed the most potential of the three in managing for all objectives.

  Citation × Citation Citation Abstract Copy Title: Assessing the Current State of Transboundary Cooperation in the International Columbia River Basin Author: Timboe, Ingrid A. The Columbia River Treaty (CRT) is often used as an example of how treaties can work to normalize, regulate, and improve the cooperative management of shared water resources between basin countries. Few would argue that, in its limited mandate to regulate hydropower generation and flood risk management for downstream communities, the CRT has been anything but a success. However, there are many aspects of water resource management, including water quality, aquatic species, and indigenous peoples' rights and responsibilities that are left unaddressed by the Treaty. These issues are of increasing importance to managers and stakeholders in river basins around the world. This paper asks, in the absence of a formal agreement governing these issues, are the United States and Canada coordinating the broader management of the Columbia River and its international tributaries? If so, around which water resource issues do they collaborate and at what level? If not, do these gaps in co-management negatively affect the basin? In order to assess the current state of transboundary water cooperation between the United States and Canada within the basin, 50 transboundary initiatives were identified and categorized into management categories including: ecosystem function, fish passage & habitat, climate change, invasive species or toxics management, and energy. Interviews were then conducted with 34 natural resource managers throughout the international basin on their work with these initiatives, specifically addressing areas where they are, and are not, collaborating at this time. The interviews revealed that, while there is a great deal of collaborative work being done, it appears largely fragmented and restricted to sub-basin activities. International, basin-wide cooperation, outside of treaty obligations under the CRT, appears limited at this time. This thesis contends that there is a need for these sub-basin activities to be networked with one another, either through the Treaty, or through an inclusive, legitimate, and transparent river basin organization.

  Citation × Citation Citation Abstract Copy Title: Host selection and wood channelization by beetles in conifer logs in western Oregon Author: Zhong, He The host preferences and wood channelization rates of scolytid and cerambycid beetles were studied at the H. J. Andrews Experimental Forest (Lane County, Oregon) during 1986 and 1987. Attack density and gallery volumes were measured in fall-felled experimental logs of four major conifer species: Douglas-fir (Pseudotsuga mensiesii (Mirb.) Franco), western hemlock (Tsuga heterophylla (Raf.)Sarg.), Pacific silver fir (Abies amabalis (Dougl.)Forbes), and western redcedar (Thu'a plicata Donn). The ambrosia beetles (Coleoptera: Scolytidae), Trypodendron lineatum (Olivier) and Gnathotrichus spp., were significantly more abundant in Douglas-fir and western hemlock than in silver fir or western redcedar, but Xyleborinus saxeseni (Ratzeburg) showed no discrimination among the four tree species. The average emergence of ambrosia beetle brood per gallery was 1.8 in spring-felled Douglas-fir logs and 2.2 in western hemlock. The data indicate a declining ambrosia beetle population emerging from these logs. About 0.16% of the sapwood volume of Douglas-fir and about 0.18% of the sapwood volume of western hemlock were removed by Trypodendron. About 0.01% of the sapwood volume of Douglas-fir and about 0.06% of the sapwood volume of western hemlock were removed by Gnathotrichus. The bark beetles (Coleoptera: Scolytidae) Dendroctonus pseudotsugae Hopkins and Dryocoetes autographus Ratzeburg excavated about 7.6% of Douglas-fir phloem surface area. Pseudohylesinus sericeus (Mannerheim) removed 6.8% of Pacific silver fir phloem surface area. Long-horned beetles (Coleoptera: Cerambycidae) excavated an additional 2.3% of Pacific silver fir phloem surface area. These data indicate that each tree species has a distinct boring insect species pool with differences in channelization rates through time. Colonization and fragmentation of fallen trees by beetles are important to the initiation of the decomposition process in forest ecosystems.
