342. [Article] Songbird communities in burned and logged stands with variable tree retention in the Canadian Rocky Mountains
By emulating natural disturbances such as wildfire, managers hope to maintain biodiversity in managed forests. Leaving residual (live) trees in harvested areas is key to this strategy. However, the effectiveness ...Citation -
Island biogeography has strongly influenced the study of biodiversity because archipelagos provide natural model systems for investigating patterns of diversity and the processes that shape ecological ...

344. [Article] The influence of forest management on headwater stream amphibians at multiple spatial scales
To effectively manage for biodiversity at broad, ecosystem scales, the influences of habitat structure at multiple spatial scales on vertebrate species must be understood. There are few studies on the ...Citation -
345. [Article] Total aboveground biomass and structure of tropical forest delineated by Projeto RADAMBRASIL in northern Rondonia, Brazil
Tropical forests are of global importance with respect to their influence on biogeochemical cycles, climatic patterns, and as large reservoirs of biodiversity. Yet, few studies have quantified their structure, ...Citation -
Riparian forests in the central Oregon Coast Range vary along a coniferous-deciduous compositional continuum. Variations in structure and composition affect water quality, fish and wildlife, biodiversity, ...

347. [Article] Relationship between plant and butterfly community composition on upland prairies of the Willamette Valley, Oregon
Small remnants of 'natural' habitats exist today throughout much of the world. Upland prairies in the Willamette Valley, Oregon have been nearly eliminated by conversion to agriculture and other uses. ...Citation -
348. [Article] Andean roots, coca, and grassroots development in the Bolivian Yungas : food sovereignty and agrarian change for native farmers
Since the 1952 Bolivian agrarian reform, farmer unions have sought to establish themselves as producers for regional markets. Development strategies led by the World Bank and IMF have largely jeopardized ...Citation -
349. [Article] A community-based approach for evaluating tradeoffs across marine ecosystem services in Oregon
As competing uses of our coastlines increase, natural resource agencies are employing marine spatial planning (MSP) to designate areas for different uses or activities in order to reduce conflicts while ...Citation -
350. [Article] Efficacy of Empirical Seed Zones: Pseudoroegneria Spicata Reproductive Phenology & Seedling Stage Traits
Ecological restoration is needed to mitigate losses to biodiversity. Restoration success is enhanced through the use of native plant materials that are genetically diverse and locally adapted. Seed transfer ...Citation
