Abstract:

The high variability in the recruitment of marine fishes is probably explained by small fluctuations in the mortality rates of early developmental stages. A popular proxy for the potential mortality of fish larvae is the study of nutritional condition (or simply "condition"). According to the growth-mortality hypothesis, a lowered condition has a high associated probability of total mortality.<br/><br/>This thesis offers new information on several aspects of nutritional condition and growth indices, by working on two main lines: <br/><br/>1) Laboratory Studies: Three main types of condition i

Abstract:

A wide variety of assessment techniques are presently available to quantify the environmental performance of an organisation. They are predominantly site- or area-specific, making them sensitive to differences in the environmental capacity of an area, and they exclude a number of global impacts. A more generic level-plane assessment tool, which quantifies the environmental burden, may therefore be needed to make a valid comparison between organisations. Furthermore, the generic process data used in these assessment tools, to inform policy decisions on a material or product, does not recognise

Abstract:

Moss dominated ecosystems are an important part of the global terrestrial carbon cycle. Over large areas, remote sensing can be useful to provide an improved understanding of these ecosystems. Two boreal mossess (Pleurozium and Sphagnum) were assessed using remote sensing based spectral vegetation indices for estimating biochemical capacity and photosynthetic efficiency by varying net photosynthesis rate via changes in water content. In the laboratory, changes in the normalized difference vegetation index (NDVI) and chlorophyll index coincided with declining photosynthetic capacity due to desi

The objective was to investigate the performance and accuracy of the satellite-derived VI products under improved sensor characteristics and algorithms. These include the "atmospheric resistant" VIs that incorporate the "blue" band for normalization of aerosol effects and the most widely-used, normalized difference vegetation ind

Self-belief about exercise strongly influences people's exercise behavior. This relationship may have significant impact on health-related physical fitness and help to address the exercise behavior deficit in the US.

The purpose of this study was to identify self-beliefs about exercise and determine if these beliefs influence behaviors and result in greater levels of physical fitness.

Abstract:

To protect and restore the biological integrity of streams, we need to be able to both detect biological degradation and infer likely causes of impairment. Managers often use biological indices to measure biological condition and detect degradation. However, the ability to detect degradation can be limited by the performance of the indices we develop. Index performance varies widely, but the sources of this variation are often unclear. In addition, although bioassessments are useful tools for detecting biological degradation, they do not identify stressors associated with impairment. My thesis

Abstract:

To assess sustainability of privately owned rangeland, a questionnaire was used to gathered data from ranches in Cooke, Montague, Clay, Wise, Parker, and Jack counties in North Central Texas. Information evaluated included: management philosophy, economics, grazing practices, environmental condition, quality of life, and demographics. Sustainability indices were created based on economic and land health indicator variables meeting a minimum Cronbach‘s alpha coefficient (α = 0.7). Hierarchical regression analysis was used to create models explaining variance in respondents’ indices scores.

Abstract:

A urbanização, quando não é devidamente planejada, potencializa impactos ambientais negativos ao ambiente e danos à saúde da população, pois traz consigo mudanças no meio físico e biológico, devido à descaracterização dos cursos dágua, mudança na geomorfologia dos terrenos, impermeabilização dos solos, corte de vegetação, verticalização das construções, entre outros. O conhecimento sobre a qualidade ambiental urbana em cidades já estabelecidas permite identificar os aspectos e impactos ambientais negativos decorrentes das ações humanas, planejar e propor ações de melhoria que favoreçam o bem e

Abstract:

Les estuaires et les zones côtières constituent des territoires à fort enjeux stratégiques économiquement et pour l'environnement. Ils assurent de nombreuses fonctions biologiques et écologiques dont celle de nourricerie et de frayère pour les poissons. Ces écosystèmes sont pourtant soumis à de multiples facteurs de stress, à la fois naturels et anthropogéniques, qui peuvent représenter une menace potentielle envers les organismes aquatiques, en particulier pour les espèces commerciales de poissons. Dans ce contexte, les effets de facteurs de stress environnementaux tels que la contamination c

Work object – Vyžuona river, which has 26 km lenght, is left affluent of Šventoji river, belongs to subbasin of Šventoji river and runs from northeast to southwest of Lithuania. Work aim – identify water quality and bounded with it live organisms of Vyžuona river. Work tasks – analyse physical-chemical water parameters of Vyžuona river, identify varietal composition of organisms, define and evaluate contamination of river objects. Work results – After the reasearch was made there was defined that Vyžuona river in Utena town (1 km from Krašuona river and Vieša river junction) belongs to average

Abstract:

Excess fine sediment from human activity is a major pollutant to streams across the U.S.; however, distinguishing human-induced sedimentation from natural fine sediment is complex. The U.S. Environmental Protection Agency recently implemented a protocol for the quantitative field assessment of human-induced sedimentation using measurements of stream geomorphology. Macroinvertebrate community composition, streambed sediment stability, and sediment composition were studied at 49 sites in the James River watershed in central Virginia. Sediment composition was found to be a stronger driver of comm

Abstract:

Este trabalho propÃe o desenvolvimento de um modelo de avaliaÃÃo e apoio ao gerenciamento integrado de resÃduos sÃlidos urbanos, com base em indicadores ambientais, especificamente nas etapas do serviÃo de coleta, varriÃÃo, capina e roÃada e no planejamento de limpeza. Uma pesquisa de opiniÃo (MÃtodo Delphi) foi realizada para determinar a importÃncia de cada um dos 24 (vinte e quatro) indicadores na composiÃÃo do Ãndice de avaliaÃÃo do gerenciamento integrado de resÃduos sÃlidos urbanos (IGU). A anÃlise estatÃstica apontou a regressÃo logÃstica ordinal como modelo matemÃtico mais adequado aos
