Centrarchid Utilization and Attraction to Newly Remediated Habitat and Structure in an Urban Lake, Syracuse, New York
Get PDFOnondaga Lake in Syracuse, New York, has experienced centuries of habitat degradation. A new substrate layer and habitat structures were added to enhance fish habitat. We hypothesized that centrarchids would respond to the enhancements. We examined centrarchid population size, reproduction, and recruitment relative to remediated habitat and their use of existing and new structures. The Largemouth Bass population and juvenile centrarchid catches were distributed more evenly between basins in 2017 than in previous years, and we concluded this is very likely an immediate response to new habitat availability and structure. In 2017, the whole-lake population estimate was the second highest recorded since sampling began in 1986, and the proportion of nests in remediated shoreline areas increased. Depth of the structures did not influence fish attraction; vegetated and grouped sites attracted greater richness and diversity, and more black bass visits than individual sites or structures
Integration of remote sensing, modeling, and field approaches for rangeland management and endangered species conservation in Central Asia
Get PDFIntegration of robust scientific approaches and on-the-ground conservation practice to “bridge the gap” between biologists and field managers is a perennial challenge in biodiversity conservation. In this thesis I present five, related case studies of integrating key scientific approaches (remote sensing techniques, habitat modeling and suitability analysis, and population modeling) with field practices to facilitate sustainable and locally accepted rangeland management, support conservation of snow leopard and Altai argali, and suggest options for tiger restoration in Central Asia. My synthesis of these case studies reveals that to advance regional long-term conservation initiatives, conservation science has to address relevant conservation problem directly, suggest solutions and recommendations that can be implemented by conservation managers given their capacity levels, fit into local knowledge systems as they pertain to the ecosystems under consideration, and focus on sharing lessons learned across projects
LIFE CYCLE ASSESSMENT AND TECHNO ECONOMIC ANALYSIS OF ELECTRICITY FROM COMMUNITY BASED BAMBOO GASIFICATION IN A RURAL AND REMOTE ISLAND OF INDONESIA
No full textBamboo is widely grown in Indonesia and is a potential energy crop for people living in rural areas. The implementation of bamboo gasification in Mentawai Island, one of rural and remote small islands in Indonesia, which follows the principle of a community-based renewable energy system, is expected to replace unsustainable conventional diesel power while also improving the socio-economic condition of the community. Life cycle assessment and techno-economic analysis are conducted to assess the community bamboo gasification system in terms of its global warming impact and economic viability. The global warming impact of community bamboo gasification ranges from -11 to 76 g CO2eq/kWh, with the highest contribution originating from synthetic fertilizer production. With a starting bamboo price at 0.20 per kWh of electricity produced, the system shows a positive net present value and a levelized cost of electricity around 84 per ton CO2 is expected by replacing diesel power with bamboo gasification
INFLUENCES OF VEGETATION MANAGEMENT STRATEGIES ON POLLINATOR ASSEMBLAGES ON POWERLINE RIGHTS-OF-WAY
Get PDFPollination carried out by insects is an essential ecosystem function required by 87% of angiosperms and contributing an estimated annual $170 billion in services worldwide. Unfortunately, pollinator populations are declining due to a variety of factors, including introduced pathogens/parasites, pesticide use, and habitat loss/degradation, all of which are caused or facilitated by humans. Powerline rights-of-way (ROWs) have been proposed as conservation/restoration areas as these habitats are able to provide nesting substrates and foraging resources. Field plots were located along powerline ROWs in central New York and in Ohio with explicit goals being to: 1) compare operational vegetation management (IVM) and experimental vegetation management techniques, 2) compare experimental techniques to one another, and 3) compare invasive-exotic plant removal on powerline ROWs by quantifying pollinator parameters (abundance, family richness, diversity, evenness), and describing assemblages to elucidate relationships between pollinators and IE plant prevalence. In New York field plots, management techniques included: tree removal using mechanical means followed by application of herbicide to cut stumps, foliar herbicide application, and brush hog mowing. In Ohio, three management outcomes and their effects on pollinators were evaluated, including tree removal, tree and woody invasive removal, and removal of all woody plants. Throughout the growing season, pollinators were collected with pan traps and sweep netting. Community measures were compared between operational and experimental treatments using paired t-tests and among treatment groups, while relationships among assemblages, treatments, months, and vegetation information were explored using multi-variate analyses. Few treatment effects were observed within community measures, however there were demonstrated differences between pollinator assemblages in operational IVM areas and brush hog mowing areas. Presence of showy honeysuckle, Lonicera bella, and glossy buckthorn, Frangula alnus, was associated with a change in pollinator assemblages and decreased pollinator abundance, richness, and diversity. Curculionidae, Vespidae, Colletidae, and Crabronidae were indicator families in plots where IE species had been removed. Additionally, Halictidae and Hesperidae were associated with disturbance levels associated with treatment methods. In order to further investigate treatment effects, researchers must follow managed areas throughout one full treatment cycle – this would allow determination of treatment half-life and variation in effects throughout the cycle
