  • Effects of Eutrophication on Stream Ecosystems
    EFFECTS OF EUTROPHICATION ON STREAM ECOSYSTEMS Lei Zheng, PhD and Michael J. Paul, PhD Tetra Tech, Inc. Abstract This paper describes the effects of nutrient enrichment on the structure and function of stream ecosystems. It starts with the currently well documented direct effects of nutrient enrichment on algal biomass and the resulting impacts on stream chemistry. The paper continues with an explanation of the less well documented indirect ecological effects of nutrient enrichment on stream structure and function, including effects of excess growth on physical habitat, and alterations to aquatic life community structure from the microbial assemblage to fish and mammals. The paper also dicusses effects on the ecosystem level including changes to productivity, respiration, decomposition, carbon and other geochemical cycles. The paper ends by discussing the significance of these direct and indirect effects of nutrient enrichment on designated uses - especially recreational, aquatic life, and drinking water. 2 1. Introduction 1.1 Stream processes Streams are all flowing natural waters, regardless of size. To understand the processes that influence the pattern and character of streams and reduce natural variation of different streams, several stream classification systems (including ecoregional, fluvial geomorphological, and stream order classification) have been adopted by state and national programs. Ecoregional classification is based on geology, soils, geomorphology, dominant land uses, and natural vegetation (Omernik 1987). Fluvial geomorphological classification explains stream and slope processes through the application of physical principles. Rosgen (1994) classified stream channels in the United States into seven major stream types based on morphological characteristics, including entrenchment, gradient, width/depth ratio, and sinuosity in various land forms.

  • The Effects of Urbanization on Natural Resources in Jamaica
    Doneika Simms. The Effects of Urbanization on Natural Resources in Jamaica . 44th ISOCARP Congress 2008 THE EFFECTS OF URBANIZATION ON NATURAL RESOURCES IN JAMAICA BACKGROUND OF STUDY AREA Jamaica is the third largest island in the Caribbean, comprising of approximately 4,400 sq. miles or 10,991 square kilometers in area. Over two-thirds of the country’s land resources consist of a central range of hills and mountains, with the Blue Mountain Range being the most significant, ranging over 6000 ft. in height (GOJ, 1994; Clarke, 2006). This means that urban development in areas such as the capital city of Kingston and other principal towns such as Montego Bay and Ocho Rios is limited to the relatively small amount of flat lands most of which has a coastal location (see figure 1). Figure 1 Showing a Map of Jamaica and the Various Cities along the Coast Source: http://www.sangstersrealty.com/jamaica_map.htm Although a significant portion of the terrain is mountainous, in several places the coastal plain extends to form broad embayments. Among these, a dry embankment on the south side of the island known as the Liguanea Plain has been occupied by the city of Kingston. The built-up area of the city spreads over 50 sq. miles and comprises the parish of Kingston and the suburban section of St. Andrew. The city is located on the eastern side of the island which is sheltered from the north-east trade winds by the Blue Mountains, hence being ideal for the major seaport of the country- the Kingston Harbour (Clarke, 2006).

  • Urbanization As a Threat to Biodiversity: Trophic Theory, Economic Geography, and Implications for Conservation Land Acquisition
    Proceedings of a Symposium at the Society for Conservation Biology 2004 Annual Meeting URBANIZATION AS A THREAT TO BIODIVERSITY: TROPHIC THEORY, ECONOMIC GEOGRAPHY, AND IMPLICATIONS FOR CONSERVATION LAND ACQUISITION Brian Czech1 ABSTRACT—Habitat loss is often cited as the primary cause of species endangerment in the United States, followed by invasive species, pollution, and direct take. Urbanization, one type of habitat loss, is the leading cause of species endangerment in the contiguous United States and entails a relatively thorough transformation from the “economy of nature” to the human economy. Principles of economic geography indicate that urbanization will continue as a function of economic growth, while principles of conservation biology indicate that the most thorough competitive exclusion occurs in urban areas. These findings suggest the need for an ecologically macroeconomic approach to conservation land acquisition strategies. “Habitat loss” is often cited as the primary cause of species these types of habitat loss are considered separate causes of endangerment in the United States, followed by invasive species endangerment, invasive species are identified as the species, pollution, disease, and direct take.

Revista Brasileira de Gestão Urbana, v. 13, e20200260. https://doi.org/10.1590/2175-3369.013.e20200260 Abstract Cities experience the extensive urban heat island effect (UHI), which continue to pose challenges for humanity's increasingly urban population, where tropical cities have experienced a continued and rapid urbanization process in the past few decades. We present the evolution of surface UHI and its controlling factors in the Metropolitan Region of Belém, over the last 16 years (2003–2018), which has experienced unique consolidated economic growth and urban transformation under wet equatorial climate. We incorporate MODIS and Landsat satellite data and evaluate statistical techniques for estimates the variation in the land surface temperature (LST) during two seasons: wet season and dry season. Our result revealed that the regions of fast urbanization resulted in a decrease of normalized difference vegetation index and increase of LST.

  • Wildland Fire in Ecosystems: Effects of Fire on Fauna
    United States Department of Agriculture Wildland Fire in Forest Service Rocky Mountain Ecosystems Research Station General Technical Report RMRS-GTR-42- volume 1 Effects of Fire on Fauna January 2000 Abstract _____________________________________ Smith, Jane Kapler, ed. 2000. Wildland fire in ecosystems: effects of fire on fauna. Gen. Tech. Rep. RMRS-GTR-42-vol. 1. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 83 p. Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals’ ability to thrive in the altered, often simplified, structure of the postfire environment. The extent of fire effects on animal communities generally depends on the extent of change in habitat structure and species composition caused by fire. Stand-replacement fires usually cause greater changes in the faunal communities of forests than in those of grasslands. Within forests, stand- replacement fires usually alter the animal community more dramatically than understory fires. Animal species are adapted to survive the pattern of fire frequency, season, size, severity, and uniformity that characterized their habitat in presettlement times. When fire frequency increases or decreases substantially or fire severity changes from presettlement patterns, habitat for many animal species declines. Keywords: fire effects, fire management, fire regime, habitat, succession, wildlife The volumes in “The Rainbow Series” will be published during the year 2000.

  • Effects of Urbanization on Stream Water Quality in the City of Atlanta, Georgia, USA†
    HYDROLOGICAL PROCESSES Hydrol. Process. 23, 2860–2878 (2009) Published online 13 August 2009 in Wiley InterScience (www.interscience.wiley.com) DOI: 10.1002/hyp.7373 Effects of urbanization on stream water quality in the city of Atlanta, Georgia, USA† Norman E. Peters* US Geological Survey, Georgia Water Science Center, 3039 Amwiler Rd., Suite 130, Atlanta, Georgia 30360-2824, USA Abstract: A long-term stream water quality monitoring network was established in the city of Atlanta, Georgia during 2003 to assess baseline water quality conditions and the effects of urbanization on stream water quality. Routine hydrologically based manual stream sampling, including several concurrent manual point and equal width increment sampling, was conducted ¾12 times annually at 21 stations, with drainage areas ranging from 3Ð7 to 232 km2. Eleven of the stations are real-time (RT) stations having continuous measures of stream stage/discharge, pH, dissolved oxygen, specific conductance, water temperature and turbidity, and automatic samplers for stormwater collection. Samples were analyzed for field parameters, and a broad suite of water quality and sediment-related constituents. Field parameters and concentrations of major ions, metals, nutrient species and coliform bacteria among stations were evaluated and with respect to watershed characteristics and plausible sources from 2003 through September 2007. Most constituent concentrations are much higher than nearby reference streams. Concentrations are statistically different among stations for several constituents, despite high variability both within and among stations. Routine manual sampling, automatic sampling during stormflows and RT water quality monitoring provided sufficient information about urban stream water quality variability to evaluate causes of water quality differences among streams.

Commerce, migration, employment, industry configuration and population increases are factors that contribute significantly to the urbanization phenomenon. With respect to the contributions of commerce, mining activities have led to the advancement and regression of cities. An abundance of literature exists on the negative effects of urbanization and mining on the environment. The main reason for the research that produced this initial findings was to determine how urbanization, when induced by mining, impacts on the environment and how to ensure future sustainable urbanization. The research was done qualitatively through interviews of knowledgeable individuals within the relevant industries within the mining town of Kathu, in the Northern Cape of South Africa. The research found that centralization of employment, resources and trade lead to urbanization, which is primary driven by the mining industry. In addition, it was observed that mining as a factor that accelerates urbanization, also impact negatively on the environment.

    Population Growth, Urbanization, and Future Wildfire Risks W. Knorr1*, L. Jiang2, and A. Arneth3 1Department of Physical Geography and Ecosystem Science, Lund University 2National Center for Atmospheric Research, and Shanghai University 3Karlsruhe Institute of Technology, Institute of Meteorology and Climate Research/Atmospheric Environmental Research, Abstract: Wildfires, as a component of terrestrial ecosystem ecology and risk factor in human societies, are affected by climatic conditions, atmospheric CO2 concentration, and population intervention. Studies of historical burned areas show that increasing population size and density significantly contributed to a secular decline in wildfire activity. While future wildfire prevalence is commonly believed to increase in a warmer and in many places drier world, increasing CO2 concentration and related in the prevalence of shrubs vs. grasses tend to lower wildfires predictions. More importantly, uncertainties in future population growth and spatial distribution under different urbanization trajectories may lead to different wildfires trends. Adopting the semi-empirical fire model SIMFIRE and combining it with the global dynamic vegetation model LPJ-GUESS, this paper explores impacts of population growth and urbanization on future wildfire risks. It reveals that a smaller population concentrated in urban areas will lead to higher wildfire prevalence, and human exposure to wildfires is driven mainly by sprawling human settlements to fire prone areas. Extended abstract: Motivation: Wildfire is a basic component of terrestrial ecology and co-evolved with natural vegetation structure and species composition (Bowman et al., 2009; Arneth et al., 2010). Wildfire is also considered as a major risk to human societies due to its damages to properties and lives and atmospheric pollution and associated health hazard (Kasischke and Penner, 2004).
