Analysis of Spatial Variation in Flood Risk Perception AgEcon
Atreya, Ajita; Susana, Ferreira.
We use hedonic property models to estimate the spatial variation in flood risk in the city of Albany, GA. In addition to knowing whether a property is in the floodplain, we have a unique dataset with actual inundation maps from tropical storm Alberto that hit Albany in 1994. In the absence of information on the structural damages caused by a flood, having information on the actual inundated area can be useful to tease out information effect of a new flood from potential reconstruction cost. We find that the discount in actually inundated properties is larger which supports our hypothesis that homeowners respond better to what they have visualized (“seeing is believing”) and also the potential reconstruction cost in addition to information effect is...

Stakeholder-led science: engaging resource managers to identify science needs for long-term management of floodplain conservation lands Ecology and Society
Bouska, Kristen L.; Missouri Cooperative Fish and Wildlife Research Unit, Department of Fisheries and Wildlife, University of Missouri; Upper Midwest Environmental Sciences Center, U.S. Geological Survey; kbouska@usgs.gov; Lindner, Garth A.; Missouri Cooperative Fish and Wildlife Research Unit, Department of Fisheries and Wildlife, University of Missouri; lindnerg@missouri.edu; Paukert, Craig P.; U.S. Geological Survey Missouri Cooperative Fish and Wildlife Research Unit, Department of Fisheries and Wildlife Sciences, University of Missouri; paukertc@missouri.edu; Jacobson, Robert B.; Columbia Environmental Research Center, U.S. Geological Survey; rjacobson@usgs.gov.
Floodplains pose challenges to managers of conservation lands because of constantly changing interactions with their rivers. Although scientific knowledge and understanding of the dynamics and drivers of river-floodplain systems can provide guidance to floodplain managers, the scientific process often occurs in isolation from management. Further, communication barriers between scientists and managers can be obstacles to appropriate application of scientific knowledge. With the coproduction of science in mind, our objectives were the following: (1) to document management priorities of floodplain conservation lands, and (2) identify science needs required to better manage the identified management priorities under nonstationary conditions, i.e., climate...

Photosynthesis, Growth and Development of Tabebuia avellanedae Lor. ex Griseb. (Bignoniaceae) in Flooded Soil BABT
Davanso,Viviane M.; Souza,Luiz A. de; Medri,Moacyr E.; Pimenta,José A.; Bianchini,Edmilson.
Morphological, anatomical and ecophysiological modifications caused by flooding in the growth and development of Tabebuia avellanedae Lor. ex Griseb. (Bignoniaceae) were studied and correlated with tolerance to the excess of water in the soil. Three-month-old plants, grown in a greenhouse, underwent a period of 56 days of flooding and a post-flooding period. Photosynthesis rate and growth decreased in T. avellanedae when flooding duration increased. Though not much tolerant, plant adapted itself to short flooding periods. This relative tolerance was probably due to the capacity of T. avellanedae in developing structures which lessened flooding effects and promoted internal diffusion of oxygen from the aerial part to the roots, such as stem fissures,...

Desarrollo de plántulas de tres especies tropicales en combinación con la inoculación micorrizica bajo inundación artificial. Colegio de Postgraduados
Martínez Sánchez, Araceli.
La presente investigación se realizó para contribuir en el conocimiento del uso de la inoculación con hongos micorrízicos vesículo arbúscular (HMVA) en especies tropicales bajo condiciones de inundación y no inundación en vivero, con el fin de obtener plantas de calidad. Por esta razón se estableció un experimento dentro de las instalaciones del Colegio de Postgraduados, Campus Montecillo, que consistió de dos fases; en la fase uno se evaluó el efecto de dos cepas micorrízicas (Glomus intraradices y Zac-19), en tres especies forestales tropicales, Tabebuia donnell-smithii, Tabebuia rosea y Haematoxylum campechiaium, se utilizó un diseño experimental con bloques completamente al azar. Las evaluaciones fueron mensualmente durante tres meses midiéndose...

Responses and adaptations of collembolan communities (Hexapoda: Collembola) to flooding and hypoxic conditions. Repositório Alice
MARX, M. T.; WILD, A.-K.; KNOLLMANN, U.; KAMP, G.; WEGENER, G.; EISENBEIS, G..
Abstract ? Standard ecological methods (pitfall traps, trunk eclectors and soil cores) were used to evaluate collembolan community responses to different flooding intensities. Three sites of a floodplain habitat near Mainz, Germany, with different flooding regimes were investigated. The structures of collembolan communities are markedly different depending on flooding intensity. Sites more affected by flooding are dominated by hygrophilic and hygrotolerant species, whereas the hardwood floodplain is dominated by mesophilic species. The survival strategies of the hygrophilic and hygrotolerant species include egg diapause and passive drifting. The physiological adaptations to hypoxic conditions of several collembolan species were analyzed using a...

Periodicidades, tendencias e previsao a partir da analise espectral dinamica da serie dos niveis do rio Paraguai, em Ladario (1990/1995). Repositório Alice
NORDEMANN, D.J.R..
As series das medias mensais e anuais dos valores do nivel do rio Paraguai, em Ladario (1990/1995), foram estudadas por varios metodos numericos que incluem: analise de Fourier, periodograma, analise espectral dinamica e regressao iterativa. A finalidade do trabalho e identificar as grandes caracteristicas do regime do rio e, atraves das principais periodicidades embutidas na serie, as possiveis causas ou os fatores que podem intervir em suas variacoes. O regime do rio nao e estacionario, porem, tentou-se utilizar apenas as oito periodicidades maiores para prever o comportamento do rio numa escala de tempo de algumas decadas.

Nest plasticity of Cornitermes silvestrii (Isoptera, Termitidae, Syntermitinae) in response to flood pulse in the Pantanal, Mato Grosso, Brazil Rev. Bras. entomol.
Plaza,Tarik G. D.; Carrijo,Tiago F.; Cancello,Eliana M..
Nest plasticity of Cornitermes silvestrii (Isoptera, Termitidae, Syntermitinae) in response to flood pulse in the Pantanal, Mato Grosso, Brazil. The Pantanal is one of the largest wetlands in the world. Since many areas in Pantanal are flooded during part of the year, it is expected that plants and animals would have mechanisms for their survival during the flooded period. This study investigated the existence of differences in nest shape and inquilines of Cornitermes silvestrii in areas influenced by the flood pulse. We measured the volume, height, width, and height/width ratio of 32 nests in flooded areas and 27 in dry areas, and performed an one-way-Anova with the quasi-Poisson distribution to determine if there were differences in the nest measurements...

Aplicacoes de tecnicas de sensoriamento remoto e sistema de informacoes geograficas na avaliacao da dinamica de inundacao no Pantanal. Repositório Alice
SILVA, J. dos S. V. da.
Este trabalho tem por objetivo avaliar a dinamica de inundacao numa secao do Pantanal, a partir da analise e integracao de dados de sensoriamento remoto com dados de campo, usando um Sistema de Informacoes Geograficas (SIG). Foram utilizados dados de cotas fluviometricas tomados nos leitos dos rios e na planicie de inundacao, inagens do satelite Landsat 5-TM, fortografias aereas verticais pancromaticas, fotografias aereas obliquas de 35mm e documentos cartograficos disponiveis da area de estudo. Elaboraram-se 5 mapas tematicos do estado de inundacao no ano hidrologico de 1989, referentes as datas de 09/04/89, 11/05/89, 12/06/89, 14/07/89 e 16/09/89, os quais foram armazenados e quantificados atraves do SIG e impressos por uma plotadora Versatec.
