Abstract:
Gray wolves are a premier example of how predators can transform ecosystems through trophic cascades. However, whether wolves change ecosystems as drastically as previously suggested has been increasingly questioned. We demonstrate how wolves alter wetland creation and recolonization by killing dispersing beavers. Beavers are ecosystem engineers that generate most wetland creation throughout boreal ecosystems. By studying beaver pond creation and recolonization patterns coupled with wolf predation on beavers, we determined that 84% of newly created and recolonized beaver ponds remained occupied until the fall, whereas 0% of newly created and recolonized ponds remained active after a wolf killed the dispersing beaver that colonized that pond. By affecting where and when beavers engineer ecosystems, wolves alter all of the ecological processes (e.g., water storage, nutrient cycling, and forest succession) that occur due to beaver-created impoundments. Our study demonstrates how predators have an outsized effect on ecosystems when they kill ecosystem engineers.

Abstract:
There is a global increase in urbanization, which contributes to the loss and fragmentation of urban wetland and pond habitats. Urban ponds have an important role in the ecology of urban areas, as they provide essential habitats for aquatic species. The objective of this study is to demonstrate ecological engineering approaches to restoring aquatic biological communities in an urban pond ecosystem, which can be used to achieve water purification of such ecosystems globally. The general approach of first cleaning out the ponds and then systematically applying different treatments of plants and fish was designed and implemented in the field. We used three replicated ponds per engineering treatment to determine which of the treatments was the best option based on an assessment of water quality and biological indicators. The main findings of this study were as follows: a combination of aquatic animals and aquatic plants can provide the best water purification performance; furthermore, macrobenthos, such as Bellamya purificata, can be used as biological indicator species for monitoring dominant species and water quality in a local urban pond ecosystem. In conclusion, maintaining biological species diversity over different trophic levels can provide the best water purification performance in urban pond ecosystems.

Abstract:
Abstract Climate-induced hazards are adversely affecting the pond ecosystems in Bangladesh. Most of the poor communities collect water from isolated ponds for drinking and other domestic needs. This paper explores how the small pond ecosystems and associated livelihoods of the coastal communities are vulnerable and argues that the pond ecosystem can be a potential resource base for community based adaptation in the coastal regions of Bangladesh. A set of quantitative and qualitative tools were applied to 309 households across five villages. The study showed that 96% of the respondents are dependent on pond water for drinking. More than 50% households expressed that temperature, rainfall variations and salinity intrusion, directly and indirectly, affect the pond water. Physical parameter values of temperature, pH and salinity from the ponds showed changes across different seasons. Drinking water scarcity during pre-monsoon (March–May), winter (Dec–Feb), disaster and immediate post-disaster period among the communities is high. Salinity intrusion and surface runoff caused by excessive rainfall in short periods also cause deterioration in the quality of pond water. However, successful examples of pond water usage emerged through the discussions, especially during a post-disaster crisis, which strengthens the idea that ponds could be a resource base for community-based adaptation in the coast of Bangladesh.

Abstract:
Pond ecosystems are biodiversity-rich habitats, which support great biological diversity and provide important ecological services, but increasingly face risk of pollution and drought events. With increase in use of road-salts, ponds become vulnerable to high levels of salt pollution and may impair their biological communities and ecosystem functions. However, understanding the impacts of these two threats combined are limited. In this study, we experimentally investigated the impacts of road-salt pollution and the expected future increase in drought events on ponds' physical conditions, communities and ecosystem functions. In a two-way factorial design, 20 experimental mesocosms were used to test the individual and combined effects of climate change-driven drought events and salt pollution on natural pond ecosystems. Treatments were presence or absence of water salinization to mimic pollution by road-salts, and drying to mimic drought events. Our drought treatment doubled water salinity during the experimental period. While salt additions significantly affected ponds' physical conditions and leaf litter decomposition, both salt additions and drying showed no independent impacts on pond biota and ecosystem functions. However, our path analysis revealed that drying indirectly reduced leaf litter decomposition and eco-system productivity through changes in ponds' physical conditions, although it did not affect biomass of insects and periphyton. Overall, our findings suggest that anticipated drought events will amplify road-salt pollution, and subsequently affect ponds' biodiversity, food webs, and ecosystem functions. Implications for restoration, conservation and climate change adaptation may include actively managing snow-melting salts and long-term monitoring of changes in ponds' biophysical conditions and ecological functions.

Abstract:
Ponds are an integral component of the hydrological system; and perform diverse roles in the biosphere. Studies on pond ecosystems are, however, often neglected, probably, due to their little size. There is no doubt that little things perform many important activities in our lives. The literature survey on pond environment studies shows very little investigative works in India; and there is no review publication on pond environment reports. In Europe, pond conservation initiative has, however, resulted in many studies on the subject. In Indian perspectives, when there is a dearth of studies on ponds, it is futile to say that there is any concrete institutional initiative on pond conservation. The 2010-2011 report of the Central Pollution Control Board (CPCB) shows that there are only 60 CPCB pond water quality monitoring stations in the country. In these scenarios, an attempt has been made in this manuscript to compile the reports on pond environment in India. The problems faced by ponds in India, mostly from pollution and encroachment, have been discussed in the text. Based on outcomes of different pond reports, some suggestions have been discussed in the end of the manuscript for an effective pond conservation initiative, and their sustainable management in India.

Abstract:
This study aims to analyze the management pattern of integrated mangrove ponds (silvofishery) as a form of creating an environmentally friendly ecosystem and the sustainable use of its resources. The study was conducted through direct observation of three silvofishery patterns that were developed based on the level of knowledge and motivation of the farm-pond community in the coastal area of archipelago Pangkajene District, Pangkep Regency. The research variables consist of 3 integrated management patterns, namely: 1) embankment path pattern, 2) trench path pattern, and 3) complangan pond pattern. These three patterns want to know their contribution to the production of Chanos chanos biomass, Penaeid shrimp, and Scylla sp., as a natural biodiversity and as indicator of environmentally friendly and sustainable ecosystems. Knowledge and motivation data on environmental management (silvofishery) are analyzed based on Structural Equation Modeling (SEM). Whereas the production of 3 silvofishery patterns were analyzed by Anova by SRD (0.05) test. The results showed knowledge and motivation contribute positively to the management of integrated silvofishery patterns. Furthermore, these three patterns of silvofishery contribute positively in maintaining pond production (milkfish, shrimp and crab), where the silvofishery pond pattern gives a greater influence value, and supports the realization of sustainable management of integrated ecosystems of mangroves and ponds.

Abstract:
Small ponds often survive the transition from forested to suburban land cover and provide habitat for many species, yet little is known about how suburbanization affects pond ecosystems. We surveyed 18 small ponds across a forest-to-suburban land cover gradient and compared how physical and chemical changes altered biological and ecosystem properties, such as nutrient and food web dynamics. Suburbanization decreased canopy cover, increased water temperatures, and increased periphyton chlorophyll a, but was associated with only weak increases in total nutrients. Yet, stable isotope analysis indicated that suburbanization altered nitrogen dynamics and resource use in the food web. We observed increases in δ15N in algae, biofilm, and frog larvae across the suburban gradient, indicative of wastewater intrusion. Suburbanization also shifted the energy and nutrient source of a dominant consumer (Rana sylvatica; = Lithobates sylvaticus) from leaf litter to algae. Overall, we identified cryptic changes to suburban pond ecosystems, highlighting that suburbanization can profoundly impact nutrients and food web resources. As residential land use increases globally, we may expect substantial shifts in nutrient dynamics and food web pathways.

Abstract:
Biologists now recognize that ecology can drive evolution, and that evolution in turn produces ecological patterns. I extend this thinking to include longer time scales, suggesting that macroevolutionary transitions can create phenotypic differences among species, which then have predictable impacts on species interactions, community assembly and ecosystem functioning. Repeated speciation can exacerbate these patterns by creating communities with similar phenotypes and hence ecological impacts. Here, I use several experiments to test these ideas in dragonfly larvae that occupy ponds with fish, ponds without fish, or both. I show that macroevolutionary transitions between habitats cause fishless pond species to be more active relative to fish pond specialists, reducing prey abundance, shifting prey community composition and creating stronger trophic cascades. These effects scale up to the community level with predictable consequences for ecosystem multi-functioning. I suggest that macroevolutionary history can have predictable impacts on phenotypic traits, with consequences for interacting species and ecosystems.

Abstract:
Migratory animals such as seabirds, salmon and whales can transport large quantities of nutrients across ecosystem boundaries, greatly enriching recipient food webs. As many of these animals biomagnify contaminants, they can also focus pollutants at toxic levels. Seabirds arguably represent the most significant biovectors of nutrients and contaminants from the ocean to the land, given their sheer numbers and global distribution. However, long-term census data on seabirds are rare. Using palaeolimnological proxies, we show that a colony of Arctic seabirds has experienced climate-induced population increases in recent decades. We then document increasing concentrations of contaminants, including polychlorinated biphenyls and cadmium, in pond sediments that are linked to biotransport by seabirds. Our findings suggest that climate-related shifts in global seabird populations will have the unexpected consequence of restructuring coastal ecosystems.

Abstract:
Phytoplankton community plays an important ecological role in the aquatic ecosystems as the primary producers and forms the fundament of the aquatic food chain for supporting the water community. Thus, the phytoplankton community structure is a good indicator of water quality due to its sensitiveness to environmental stresses. Two newly dug ponds in Institut Teknologi Sumatera may give an opportunity to study the early colonizing stages of various freshwater communities including phytoplankton. The study attempted to determine the composition and abundance of phytoplankton. Samples were collected from two ponds (A and C) in the reservoir water of Institut Teknologi Sumatera. The content of Phosphorus (P), Nitrogen (N), and Chlorophyll-a (algae biomass) were determined. Phytoplankton had higher diversity in Pond C than Pond A in the study period, in which a total of seven taxa were found, namely Bacillariophycea, Cyanophyceae, Chlorophyceae, Conjugatophyceae, Dinophyceae, Euglenophyceae, Gymnodiniaceae. The most species abundance of both ponds was Peridinium sp. and Trachelomonas sp. The Pond C had the highest mean value of the Shannon-Wiener diversity index. The Linear mixed-effect model showed that low turbidity will result in high phytoplankton diversity. The finding of this study suggests that higher phytoplankton diversity would achieve a natural carrying capacity, and thus would serves as an indicator of ecosystem health.

Actualmente existen diversos problemas medioambientales, dos de ellos corresponden a la futura crisis energética, debido al agotamiento de los combustibles fósiles, y a la existencia de aguas residuales con altas concentraciones de nitrógeno y carbono. Un microorganismo llamado microalga podría ser una potencial solución a estos problemas, ya que éstos consumen nitrógeno y carbono para acumular lípidos en su medio intracelular, el cual posteriormente es procesado para producir biocombustibles. Sin embargo, la producción de energía a partir de microlagas es aún muy cara, es por eso que se debe optimizar este proceso, en este trabajo se abordará la estrategia de optimización a través del acoplamiento de ecosistemas, los cuales corresponden a: Piscina de microalgas (PM), digestor anaeróbico (DA) y una planta de tratamiento de aguas (PTA). El objetivo general de esta investigación es encontrar el arreglo espacial óptimo entre ellos. Se diseñaron y calibraron modelos matemáticos simples para el ecosistema PM y PTA. La calibración se llevó a cabo usando las curvas de nitrógeno y de demanda química de oxígeno (DQO) en paralelo, con una suma de errores de 22.5% para el PM y de 38.5% para el PTA. Los parámetros obtenidos son comparables a los encontrados en la literatura. Los ecosistemas fueron acoplados a través de sus flujos de DQO y de nitrógeno, y las siguientes funciones objetivo fueron definidas: 1) Maximizar el metano producido 2) Maximizar la energía total producida y 3) Maximizar las ganacias obtenidas gracias al valor del metano y de la biomasa producida. Además, fueron consideradas restricciones medioambientales, tales como la concentración de nitrógeno y la DQO en la salida del sistema. Si lo que se maximiza es el metano, se obtienen 99.96 [mol]. El reactor anaeróbico es el más grande y recibe la alimentación más alta, el CH4 generado corresponde al 72.4% del máximo teórico. En este caso, el arreglo espacial no puede ser presentado como una cadena de etapas porque el diagrama de flujos obtenido es uno circular y por lo tanto el orden entre cada ecosistema es irrelevante para el proceso. Si la ganacia y la energía total producida son maximizadas, se obtuvo 343.6 US$ y 115.53 [kWh], respectivamente. El ecosistema de tratamiento de aguas recibe la alimentación más alta, el cual produce el mayor beneficio económicos y la mayor producción de energía. El metano producido es un 21% del máximo teórico. En ambos casos, el arraglo espacial obtenido son iguales, debido a la presencia de mínimos locales y a la similtud de las funciones objetivo. Además, es posible concluir que el primer paso del proceso debiese ser el ecosistema PTA, luego el DA y finalmente el PM. Así, se pudo cumplir el objetivo general de este trabajo. Finalmente, la metodología usada es capaz de cumplir los objetivos planteados, incluso es posible escalar el problema agregando otros ecosistemas o usarla en otras aplicaciones." "In recent years several environmental problems have come about, two of them are an energy crisis as a result of fossil fuel exhaust and the waste water created with high nitrogen and carbon concentrations. A potential solution of the aforementioned problems is contained in the properties of microalgae, which is a microorganism that can accumulate lipids in its intracellular medium. These lipids can be processed and converted into biofuel by allowing microalgae to consume nitrogen and an organic source from the medium. However, energy production from microalgae is too expensive in comparison with fossil fuel and thus there is a need to optimize this process. The strategy of optimizing by coupling ecosystems will be carried out in this work. The ecosystems that will be coupled are: Microalgae pond (MP), anaerobic digester (AD) and wastewater treatment plant (WWT). The general objective of this research is to find the optimal spatial arrangement among them through mathematical modelling. Simple mathematical models were designed and calibrated to MP and WWT ecosystem. Calibrations were carried out using nitrogen and chemical oxygen demand (COD) curves in parallel with a sum error of 22.5% in MP and 38.5% in WWT. Obtained parameters are similar to ones found in previous literature. Ecosystem were coupled through COD and nitrogen flows and the following objectives functions were defined: 1) Maximize methane produced 2) Maximize total energy produced and 3) Maximize profit due to the value of methane and microalgae biomass produced. Environmental constraints were considered, such as nitrogen and COD because they are in the output. When the methane produced was maximized it reached 99.96 [mol]. The anaerobic reactor has the biggest size, it receives the highest input flow, and CH4 generated is the 72.4% of maximum theoretical methane production. This result determined that the spatial arrangement can not be summarized by a chain of processes since the flowsheet obtained is a circular one and thus the order is irrelevant for the process. When profit and total energy produced are maximized, it was obtained 343.6 US$ and 115.53 [kWh]$ respectively. Waste water ecosystem received the biggest input flow, which produced the majority of amount of revenues and energy. Methane produced is equal to 21% of maximum theoretical. In both cases, the spatial arrangements obtained are equals due to the presence of local minima and the similarity in the objective function. These calculations allow to conclude the best order of the ecosystems: WWT, AD, and finally MP. Finally the methodology is enough to reach the objectives of this work, even it is possible to scale the system adding more than one ecosystem or using this methodology in other fields.

Abstract:
Integrating green or blue space into cities can provide environmental and public health benefits which maximize urban sustainability. One type of green/blue infrastructure that has been understudied is urban stormwater ponds, which are used to manage stormwater runoff. Their performance is typically only evaluated in terms of hydrological functions, with little focus on their capacity to provide ancillary benefits to communities. In this exploratory study, an online survey was distributed to six neighbourhoods in the City of Ottawa, ON to gain insight into the social value of urban stormwater ponds. The results revealed that despite some disadvantages, most respondents visited their neighbourhood stormwater ponds regularly and largely appreciated the cultural ecosystem services provided by these ponds, such as opportunities for experiencing nature, especially wildlife, and outdoor recreation. These findings can be used to improve the multifunctionality of stormwater ponds and optimize both environmental and social sustainability outcomes.

Abstract:
In urban areas, stormwater management ponds (SWPs) are built to mitigate polluted runoff. Although these ponds are increasing in numbers, their ecology is not well understood. Physical and chemical characteristics of 17 SWPs in the City of Ottawa were measured to determine the drivers of phytoplankton biomass (Chl. a) and primary production (PP). While total phosphorus was the best predictor of algal biomass in the ponds (as in lakes), the imperviousness of the catchment could also predict Chl. a. Planktonic PP in two ponds measured seasonally was more closely related to water residence time than to nutrient concentrations with rates approaching at times the theoretical maximum for aquatic systems. In one pond, whole ecosystem metabolism, estimated using diel changes in dissolved oxygen and δ18O-O2, suggested that these hypereutrophic systems were net sinks for carbon in the summer but likely sources to the atmosphere at other times of the year.

Abstract:
The ecology of ponds is threatened by urbanisation and as cities expand pond habitats are disappearing at an alarming rate. Pond communities are structured by local (water quality, physical) and regional (land-use, connectivity) processes. Since ca1904 >80% of ponds in Birmingham, U.K., have been lost due to land-use intensification, resulting in an increasingly diffuse network. A survey of thirty urban ponds revealed high spatial and temporal variability in water quality, which frequently failed environmental standards. Most were eutrophic, although macrophyte-rich, well connected ponds supported macroinvertebrate assemblages of high conservation value. Statistically, local physical variables (e.g. shading) explained more variation, both in water quality and macroinvertebrate community composition than regional factors. Nonetheless, habitat availability within the wider landscape was important. Ecosystem functioning (leaf-litter breakdown) along a rural-urban gradient was confounded by habitat area, despite a decrease in functional redundancy. Ponds are identified that promote network connectivity and management of land-use within 100m may buffer against diffuse pollution with reductions in riparian shading required to improve growth conditions for oxygenating vegetation and to reduce nutrient levels. The results indicate that many urban ponds are threatened habitats that require active management to protect and restore water quality, biodiversity and ecosystem functioning.

Abstract:
This doctoral dissertation was produced in a cooperation between Halmstad University (Wetland Research Centre, School of Business and Engineering) and Lund University (Limnology & Marine Biology, Department of Ecology). Abstract . Wetland creation at large, regional scales is implemented as a measure to abate the biodiversity loss in agricultural landscapes and the eutrophication of watersheds and coastal areas by non-point source nutrient pollution (mainly nitrogen). The consequences of creating many new wetlands for biodiversity conservation and nutrient reten- tion (ecosystem functioning) in agricultural landscapes are still relatively unknown, both on local (per wetland) and regional (per landscape) scales. In Sweden, wetland creation has progressed already since the 1990s, and by now larger numbers of created wetlands are present, mainly in the intensively farmed landscapes of southwestern Sweden. This thesis aimed to investigate the following aspects in these systems: (i) their large-scale effects on biodiversity, (ii) their functional diversity of bacterial denitrifiers, (iii) the abiotic and biotic influences on wetland ecosystem functioning, (iv) the potential for biodiversity-function links, and (v) the potential for functional links and joint functioning.(i) Created wetlands hosted diverse assemblages of macroinvertebrates and plants. They maintained a similar com- position and diversity as natural ponds in agricultural landscapes. The environmental conditions per wetland did hardly affect macroinvertebrate and plant assemblages, and the prerequisites for nutrient retention did neither. In landscapes were wetland creation efforts had increased the total density of small water bodies by more than 30%, macroinver- tebrate diversity of created wetlands was facilitated on both local and regional scales. (ii) Diverse communities of denitrifying bacteria with the capacity for conducting different denitrification steps (functional types) were present in all investigated wetlands. The richness of denitrifying bacteria communities was affected by nitrate concentration and hydraulic loading rate, which may potentially be relevant for the nitrogen retention function of created wetlands. The diversity across different functional types of bacterial denitrifiers increased with nitrate concentration. (iii) Both abiotic and biotic factors influenced ecosystem functions of created wetlands. Variation in nitrogen retention was associated to nitrate load, but even to vegetation parameters. In wetlands with constant nitrate load, planted emergent vegetation facilitated nitrogen retention compared to other vegetation types. In wetlands with variable loads, nitrogen retention was facilitated if nitrate load was high and many different vegetation types were present; nitrogen load could explain the majority of the variation in nitrogen retention compared to vegetation parameters. Phosporus retention of created wetlands was best explained by vegetation parameters. Litter decomposition was inhibited at high nitrate to phosphorus ratios. Methane production increased with age and decreased with plant cover. (iv) Biodiversity may facilitate wetland ecosystem functions, particularly in dynamic wetland ecosystems. Nitrogen retention increased with vegetation type diversity, phosphorus retention capacity with plant richness, and litter decomposition with macroinvertebrate diversity. (v) Created wetlands have the capacity of sustaining several parallel ecosystem services. Some wetland functions were coupled; nitrogen retention increased with fast litter decomposition. On the other hand, methane emission and nitro- gen retention were independent of each other, as were nitrogen and phosphorus retention.In conclusion, created wetlands have the potential to at least partly abate the lost biodiversity and multifunctionality caused by the past extensive destruction of natural wetlands in agricultural landscapes.

Abstract:
Urbanization involves the conversion of natural areas to impervious surfaces, which can lead to an increase in the frequency and severity of flood events in cities. To mitigate flood risk, stormwater ponds are constructed to manage urban runoff. Stormwater ponds can also be colonized by wildlife, but their suitability as habitat is disputed due to potential toxicological risks. This study assessed the suitability of stormwater ponds as habitat for the bioindicators Odonata (dragonflies and damselflies) and determined environmental factors that impact their community structure. Odonata (adults, nymphs and exuviae) were sampled at 41 stormwater ponds and 10 natural reference ponds across the National Capital Region of Canada, with a subset of ponds sampled over four years (2015-2018). Plant communities, water quality and surrounding land cover were analyzed at each pond to determine their impacts on Odonata community structure. Overall, stormwater ponds had lower Odonata abundance and a greater variation in species richness and community structure compared to natural ponds but had comparable dragonfly reproduction rates. Plants were the most significant driver of Odonata communities, as stormwater ponds with a high richness of native wetland plants had higher Odonata abundance and community structures similar to natural ponds. Water quality was the second most important driver of Odonata communities with dragonflies showing greater sensitivity to urban contaminants than damselflies. While stormwater ponds had higher concentrations of trace elements than natural ponds (e.g. Ni, V, As), concentrations were generally below toxic levels for all elements except copper and chloride, the latter likely an input from winter road salting. Surrounding land cover was the least important factor affecting Odonata communities. In conclusion, this research demonstrated the importance of local-scale factors related to plants and water quality in sustaining Odonata communities and specifies recommendations for stormwater pond design and maintenance that enhance urban biodiversity.

Salt marshes are physically, chemically, and biologically dynamic environments found globally at temperate latitudes. Tidal creeks and marshtop ponds may expand at the expense of productive grass-covered marsh platform. It is therefore important to understand the present magnitude and drivers of production and respiration in these submerged environments in order to evaluate the future role of salt marshes as a carbon sink. This thesis describes new methods to apply the triple oxygen isotope tracer of photosynthetic production in a salt marsh. Additionally, noble gases are applied to constrain air-water exchange processes which affect metabolism tracers. These stable, natural abundance tracers complement traditional techniques for measuring metabolism. In particular, they highlight the potential importance of daytime oxygen sinks besides aerobic respiration, such as rising bubbles. In tidal creeks, increasing nutrients may increase both production and respiration, without any apparent change in the net metabolism. In ponds, daytime production and respiration are also tightly coupled, but there is high background respiration regardless of changes in daytime production. Both tidal creeks and ponds have higher respiration rates and lower production rates than the marsh platform, suggesting that expansion of these submerged environments could limit the ability of salt marshes to sequester carbon.

Abstract:
Field measurement and modelling of the material cycle are carried out for the cultivation pond of penaeid shrimp Penaeus japonicus. The main purpose of the present study is to investigate the sustainability of coastal shrimp aquaculture, which is increasingly being questioned due to many problems like disease, excessive nutrient enrichment, and low levels of dissolved oxygen tension. Despite the great economic importance of shrimps and their suitability to aquaculture, little is known about the material cycle through the cultivation pond. Additionally, the collapse of shrimp aquaculture in most tropical countries may be attributed to the lack of ecological, biological, and environmental understanding. Hence field measurement of water quality is conducted in the shrimp cultivation pond, which locates in the Kyushu district of Japan. Various environmental factors such as water temperature, salinity, and the concentrations of dissolved oxygen, nutrients, and chlorophyll a are monitored for the water in the pond and that drawn from the outer sea during November and December of 2006. In addition to field measurement, one dimensional numerical model is developed for the shrimp cultivation pond to understand the material cycle through the pond in a quantitative manner. The numerical model consists of physical, lower trophic-level ecosystem, and shrimp growth submodels. The numerical values of physical and physiological parameters are calibrated to achieve the best agreement between observed and simulated results. By integrating results from field measurement and numerical simulation, it is revealed that the quality of water in the cultivation pond is quite different from that drawn from the outer sea. In particular the concentration of chlorophyll a is much higher in the cultivation pond due to large primary production. The results of the numerical simulation show that the high productivity is attributed partly to the activities of shrimps. The information from field measurement and the simulated results of the developed numerical model are useful to optimize the food quantity and quality, the population density of shrimps, and the design of watermills or the other equipments to improve the water quality for sustainable use of coastal shrimp cultivation pond.

Abstract:
Cities are growing at a phenomenal pace and the speed has created a huge gap between the urban dwellers and nature. Though development of cities are driven by many economic factors and ecological driving factors are acknowledged in recent times, water resources still lack importance. The significance of urban water bodies are mainly in two ways: one is to help the survival of the water dependent ecosystem and landscape and the other is to recharge the water beneath the ground. Since ancient times water had a great role in human culture in many ways through rituals and lifestyle, especially in India. Creating huge man made reservoirs, for agriculture and day to day uses. Unfortunately, in recent times anthropogenic activities have created the worst phase of degradation of natural resources and mainly water. So as an urban designer there is a great social responsibility and commitment for building up a better and healthy city have a key role in integrating such natural resources positively with the newly heading urbanized world.In this study an attempt to make a qualitative analysis of the current scenario of urban ponds in Trivandrum has been made.

Abstract:
The main objective of the surface water monitoring – periodically to conduct water quality testing, to find out the possible sources of pollution in time and to warn population. Water samples for analysis of surface water bodies – rivers Raseika (Raseiniai district, central Lithuania) were taken during the autumn season. The river Raseika belongs to the basin of the river Jura. This river was drained for many times and has a lot of ponds. The treated urban sewage of Raseiniai wastewater treatment plants flows to this river. Also the river Raseika is polluted by population sewage, which are not col-lected and treated. The river Raseika flows through Dubysa Regional Park area, which was established in 1992 to preserve Dubysa erosive valley landscape, natural and cultural heritage values: the picturesque Dubysa valley; significant geomor-phological, hydrographic, cultural, botanical and landscape values, natural ecosystem stability, biota components, unique flora and fauna, natural fish migration routes and spawning grounds. Six points were selected to carry out the monitoring of the river Raseika. The nitrogen concentrations were mostly not corre-sponding to the standards. Most of the ascendances were found in samples where the treated urban sewage of Raseiniai city wastewater treatment plants flows in the river.

Abstract:
Thermal Management System developed for aerospace carriers (missile, aircraft, space station), bounds processes of generation and dissipation, transfer and conversion of power, refrigeration, and of bio-metabolism related substances. Local ecosystem of the carrier combines technological and biological subsystems, interacting with internal and outer spaces. The conceptual IETM System performs recovery of waste thermal energy, generation of “free” refrigeration, and recovery of byproducts into safe coolants (ammonia - water). Thermal Management solutions include novel technologies of intensification of the heat transfer and of conversion of the waste resources into refrigeration for extension of cooling capabilities for high heat radars, lasers and microwave generators. The IETM includes Vacuum-Evaporative Refrigeration (VER) utilizing “free natural” vacuum and waste heat-activated refrigeration circuits. VER generates ~1000 Btu of “free” cold per pound of wastewater or ammonia. The introduced high performance microstructure of compound electrohydrodynamic (EHD) boundary microsystems intensifies nucleate boiling, preventing dryout. The coils of the microwires adjoin to the boiling surface and form precision microstructure of heat sink with microchannels between the coils and the surface. The microcavities form the active bubbling nucleation sites along the spiral zones of contacts of the microwires and basic surfaces. The fins-microelectrodes develop additional heat transfer surface and evenly distributed spiral zones of the nucleation sites. Like fibers of a fine wick, the electric forces in EHD capillary structures of the microelectrodes retain the liquid and push out generated vapor bubbles from the surface. Good manufacturability and performance of novel MEMS are based on well-developed materials and common winding technology “borrowed” from electrotechnical industry. Conversion of waste resources into refrigeration and EHD activation of boiling allow meeting strong limitations in weight, reliability and consumption of energy. These conceptual approaches provide diversities in refrigeration capabilities for IETM.

Abstract:
The muskrat (Ondatra zibethicus) is a common, semi-aquatic rodent native to the United States. It spends its life in aquatic habitats and is well adapted for swimming. Although muskrats are an important part of native ecosystems, their burrowing and foraging activities can damage agricultural crops, native marshes and water control systems, such as aquaculture and farm ponds and levees. Such damage can significantly impact agricultural crops like rice that rely on consistent water levels for growth. Laws, regulations, and ordinances regarding the take of muskrats varies by state and province where they are found and regulations on seasons, bag limits, and type of traps or devices that can be used to take them must be carefully followed.
