Ecophysiology Of Seedlings Of Three Mediterranean Pine Species In Contrasting Light Regimes, Tala Awada, Kalliopi Radoglou, Mariangela N. Fotelli, Helen I. A. Constantinidou

School of Natural Resources: Faculty Publications

Seasonal dynamics of net photosynthesis (A_net) in 2-year-old seedlings of Pinus brutia Ten., Pinus pinea L. and Pinus pinaster Ait. were investigated. Seedlings were grown in the field in two light regimes: sun (ambient light) and shade (25% of photosynthetically active radiation (PAR)). Repeated measures analyses over a 12-month period showed that A_net varied significantly among species and from season to season. Maximum A_net in sun-acclimated seedlings was low in winter (yet remained positive) and peaked during summer. Maximum A_net was observed in June in P. pinea (12 μmol m^–2 s^–1), …

Air Temperature Errors Caused By Air Filter And Construction Effects On Hmp45c Temperature Sensors In Weather Stations, K. G. Hubbard, X Lin

School of Natural Resources: Faculty Publications

For non–ventilated air temperature measurements at weather stations, both ambient wind speed and solar radiation are known to affect the magnitude of air temperature measurement errors. The objective of this study is to explore the effect of the sensor’s housing and to quantify any stagnation or conduction errors. The HMP45C temperature and relative humidity sensor with a Gill radiation shield is widely used in remote monitoring sites. The use of a filter in the HMP45C leads to loss of ventilation, while the protrusion of the sensor housing below the Gill shield exposes it to radiation loading and potentially increased conduction …

Novel Technique For Remote Estimation Of Co2 Flux In Maize, Anatoly A. Gitelson, Shashi B. Verma, Andrés Viña, Donald C. Rundquist, Galina P. Keydan, Bryan Leavitt, Timothy J. Arkebauer, George G. Burba, Andrew E. Suyker

School of Natural Resources: Faculty Publications

There is considerable interest in assessing the magnitude of carbon sources and sinks for agricultural lands, grasslands, and forests. In this paper, we propose a novel technique to remotely assess CO₂ fluxes in maize using reflectances (ρ) in two spectral channels either in the green around 550 nm or in the red edge near 700 nm and the NIR (beyond 750 nm). Differences of reciprocal reflectances [(ρ_Green)^-1 - (ρ_NIR)^-1] and [(ρ_RedEdge)^-1- (ρ_NIR)^-1] accounted for more than 90 percent of the variability in mid-day canopy …

Remote Estimation Of Leaf Area Index And Green Leaf Biomass In Maize Canopies, Anatoly A. Gitelson, Andrés Viña, Timothy J. Arkebauer, Donald C. Rundquist, Galina P. Keydan, Bryan Leavitt

School of Natural Resources: Faculty Publications

Leaf area index (LAI) is an important variable for climate modeling, estimates of primary production, agricultural yield forecasting, and many other diverse studies. Remote sensing provides a considerable potential for estimating LAI at local to regional and global scales. Several spectral vegetation indices have been proposed, but their capacity to estimate LAI is highly reduced at moderate-to- high LAI. In this paper, we propose a technique to estimate LAI and green leaf biomass remotely using reflectances in two spectral channels either in the green around 550 nm, or at the red edge near 700 nm, and in the NIR (beyond …

Towards A Unified Approach For Remote Estimation Of Chlorophyll-A In Both Terrestrial Vegetation And Turbid Productive Waters, Giorgio Dall'olmo, Anatoly Gitelson, Donald C. Rundquist

School of Natural Resources: Faculty Publications

In this study we tested the applicability of a method, originally developed for terrestrial plant leaves, to retrieve chlorophyll-a concentrations from reflectance spectra of turbid productive waters. We tuned the conceptual model according to the optical characteristics of the aquatic medium, and accurately predicted chlorophyll-a concentrations in water bodies over a wide range of optical conditions. Our results provide evidence that this technique may be considered as a general solution, independent of the type of medium, for assessing chlorophyll concentration in optically deep media using remotely sensed data.

Avhrr-Based Spectral Vegetation Index For Quantitative Assessment Of Vegetation State And Productivity: Calibration And Validation, Felix Kogan, Anatoly A. Gitelson, Edige Zakarin, Lev Spivak, Lubov Lebed

School of Natural Resources: Faculty Publications

The goal of the work was to estimate, quantitatively, vegetation state and productivity using AVHRR-based Vegetation Condition Index (VCI). The VCI algorithm includes application of post-launch calibration to visible channels, calculation of NDVI from channels’ reflectance, removal of high-frequency noise from NDVI’s annual time series, stratification of ecosystem resources, and separation of ecosystem and weather components in the NDVI value. The weather component was calculated by normalizing the NDVI to the difference of the extreme NDVI fluctuations (maximum and minimum), derived from multi-year data for each week and land pixel. The VCI was compared with wheat density measured in Kazakhstan. …

Survival Rates And Recovery Distributions Of Canada Geese Banded In Nebraska, Larkin A. Powell, Mark Vrtiska, Nick Lyman

School of Natural Resources: Faculty Publications

We analyzed banding and recovery data for Canada geese (Branta canadensis) banded in Nebraska during 1990–2000. Survival rates were lower during 1996–2000 (adult: 0.688, SE = 0.016; juvenile: 0.611, SE = 0.029), than 1990–1995 (adult: 0.727, SE = 0.011; juvenile: 0.639, SE = 0.024). Average juvenile-to-adult ratio from banding data was 0.834 (SD = 0.485), resulting in an annual population growth rate (λ) estimate for 1990–1995 of 0.995 (95% CI = 0.021), and 0.922 (0.018) for 1996–2000. Our recovery analysis suggests that 67% of geese banded in Nebraska are shot in Nebraska. Over 30% of both juvenile and adult recoveries …

Urban Canada Geese In Georgia: Assessing A Golf Course Survey And A Nuisance Relocation Program, Larkin A. Powell, Michael J. Conroy, Kipling S. Balkcom, Joe Caudell

School of Natural Resources: Faculty Publications

Nuisance complaints about Canada geese (Branta canadensis), have risen in recent years. In Georgia, managers have responded by relocating some nuisance geese to rural areas. During 1993–1996, we used band recoveries of relocated geese to determine the efficacy of relocation as a management strategy. We also used data from a post-card survey of golf courses to monitor the urban subpopulation of Canada geese in Georgia during 1998–2001. Flocks considered by golf course superintendents to be a nuisance were larger (1998: 48.8 geese, 1999: 71.5, 2000: 73.2, 2001: 67.2) than nonnuisance flocks (1998: 13.1 geese, 1999: 16.7, 2000: 25.8, 2001: 18.1). …

Temporal Variations Of Extreme Precipitation Events In The United States: 1895–2000, Kenneth E. Kunkel, David R. Easterling, Kelly Redmond, Kenneth Hubbard

School of Natural Resources: Faculty Publications

A newly available data set of daily precipitation observations was used to study the temporal variability of the frequency of short-duration extreme precipitation events for 1895–2000 in the conterminous United States. Event durations of 1, 5, 10, and 30 day and return periods of 1, 5, and 20 year were analyzed. For all combinations of duration and return period, heavy precipitation frequencies were relatively high during the late 19th/early 20th Centuries, decreasing to a minimum in the 1920s and 30s, followed by a general increase into the 1990s. The frequencies at the beginning of the 20th Century were nearly as …

Fire Climate Interactions And Predicting Fire Season Severity In The Mediterranean Climate Areas Of California, Southern Oregon, And Western Nevada, Alan H. Taylor, Carl N. Skinner, Andrew M. Carleton, Scott L. Stephens, Valerie Trouet, Bernd Haupt, Andrew Pierce

JFSP Research Project Reports

• We identified annual area burned for 37 National Forests in Washington, Oregon, and California between 1929 and 2004 from annual fire reports. Variation in area burned each year on National Forest lands is strongly related (r2 = 0.87) to total area burned in California. This indicates area burned in National Forests is a good indicator of total area burned in a state. • Four large groups of National Forests were identified that had similar temporal patterns of fire extent. Three of these groups were spatially coherent and included mainly: 1) Washington and northern Oregon; 2) northern California and California …

Ecological Considerations In The Design Of River And Stream Crossings, Scott D. Jackson

Scott D. Jackson

As long linear ecosystems, rivers and streams are particularly vulnerable to fragmentation. There is growing concern about the role of road crossings – and especially culverts – in altering habitats and disrupting river and stream continuity. Most of the culverts currently in place were designed with the principal objective of moving water across a road alignment. Little consideration was given to ecosystem processes such as the natural hydrology, sediment transport, fish and wildlife passage, or the movement of woody debris. It is not surprising then that many culverts significantly disrupt the movement of aquatic organisms. Survival of individual animals, facilitation …

Determination Of Home Techniques For Storing And Conserving Food In The Homes Of Cuambo And La Rinconada In Imbabura Province, 2001-2002, Marisol Caicedo Barrios

Theses and Dissertations

In Ecuador, there is a grave socioeconomic nutritional problem, and it is seen clearest in Imbabura province in the communities of Cuambo and La Rinconada. One of the biggest problems is inadequate food, due principally to the poor food storage and conservation habits. Considering this problem, it is necessary to deepen the knowledge of improved traditional techniques for storing and conserving food, through which families can store and manage their product better, controlling and avoiding losses due to insects, rodents, and climate, and guaranteeing conservation of the same. The investigation was oriented to implement alternative, improved storage and conservation technologies …
