Resumen
Meltwater mixing in small arctic lakes at Saqvaqjuac (63°68′N, 90°40′W) was studied in 1980 and 1981 to evaluate the applicability of theoretical lake water renewal times to the modeling of ice-covered lakes. Two 370-GBq tritium additions were made to 7.09-ha P&N Lake. One was mixed with the unfrozen water at the time of maximum lake-ice thickness (May 1980) and the other was mixed with the lake immediately after freezing (October 1980). Dye experiments were also performed at four lakes to define the spatial and temporal distribution of the inflow and icemelt layers. Results from the tritiated water and dye addition experiments, as well as conductance and temperature profiles, showed that during ice-on, the cold low-density meltwater floated in a thin layer 0–100 cm beneath the ice, extended over the entire subice-surface area, and left the lake without mixing with the heavier subice water. These results imply that (1) lake models incorporating a lake flushing rate term need to be reevaluated to accommodate the lack of meltwater mixing beneath spring ice and (2) more attention should be given to the early spring meltwater chemistry and its distribution within the upper lake strata.

Resumen
The effects of water color on lake stratification, mean epilimnetic irradiance, and lake temperature dynamics were examined in small, north-temperate lakes that differed widely in water color (1.5–19.8 m–1). Among these lakes, colored lakes differed from clear lakes in the following ways: (i) the epilimnia were shallower and colder, and mean epilimnetic irradiance was reduced; (ii) the diel temperature cycles were more pronounced; (iii) whole-lake heat accumulation during stratification was reduced. The depth of the epilimnion ranged from 2.5 m in the clearest lake to 0.75 m in the most colored lake, and 91% of the variation in epilimnetic depth was explained by water color. Summer mean morning epilimnetic temperature was ~2 °C cooler in the most colored lake compared with the clearest lake. In clear lakes, the diel temperature range (1.4 ± 0.7 °C) was significantly (p = 0.01) less than that in the most colored lake (2.1 ± 1.0 °C). Change in whole-lake heat content was negatively correlated with water color. Increasing water color decreased light penetration more than thermocline depth, leading to reduced mean epilimnetic irradiance in the colored lakes. Thus, in these small lakes, water color significantly affected temperature, thermocline depth, and light climate.

Resumen
The distribution of lake trout (Salvelinus namaycush) with respect to water temperature, dissolved oxygen, and light intensity was surveyed in three small Canadian Shield lakes at the Experimental Lakes Area, northwestern Ontario. Based on hydroacoustic and gillnet surveys, there was considerable variation among lakes in temperatures occupied by lake trout during the summer. During the day, lake trout were concentrated at 4-8°C in Lake 375, broadly distributed from 6 to 15°C in Lake 442, and concentrated in the epilimnion at 19°C in Lake 468. At night, lake trout in all lakes occupied epilimnetic waters at 19-20°C. Lake trout inhabited highly oxygenated water, with 75-90% of fish at >6 mg dissolved oxygen ·L-1 throughout the spring and summer in all three lakes. Light intensity did not affect lake trout distribution in Lake 468 but may have contributed to lake trout daytime descent into cool waters in Lakes 375 and 442. We suggest that previously assumed niche boundaries of lake trout do not adequately describe critical habitat for the species in small lakes, the same lakes that are likely most sensitive to erosion of such habitat.

Resumen
The patterns of spatial distribution of planktonic crustaceans changed with increasing lake size. Greatest abundances were often found offshore in smaller lakes but nearshore in larger lakes. Interstation similarity of plankton, measured with Jaccard's and Renkonen's indices, was higher in small- to middle-sized lakes and lower in very small and very large lakes, indicating that mechanisms existed at both ends of the size spectrum which prevented plankton from mixing horizontally. The information content of a single central lake sample was evaluated against a lake average from 9–10 stations. To capture at least 80% of the species present, one station was sufficient only in smaller lakes, three to six stations were needed in the smallest and medium-sized lakes, and more than nine stations were needed in the largest lake. The single central station in small- and medium-sized lakes represented average total plankton abundance and dominant species relatively well but underestimated rare species. In larger lakes, lake average plankton was not well characterized by a single station. In Lake Superior, the central station reflected the offshore but not the nearshore community. Neither plankton abundance nor the number of species appeared related to lake size in the series of lakes investigated.

Resumen
The hypolimnetic oxygen consumption rates of 28 Ontario lakes were calculated and compared with lake morphology, chemical concentrations, and productivity measures. In most cases, hypolimnia had upper zones where average light intensities were greater than 1% of surface light. In these layers, oxygen dynamics were highly variable from year to year and production rather than consumption was common. The ratio of areal oxygen consumption below the 1% light level to planktonic production corrected for retention was studied as a measure of percent available material decomposed. Using stepwise multiple regressions, we found this parameter to be related to mean thickness of the hypolimnion, lake organic carbon, and iron concentrations. The range of lake productivities in the data set was small and did not explain a significant portion of the variance in areal hypolimnetic depletion rates.

Resumen
The article presents the results of studies of the environmental properties of organochlorines which differ in properties and origin, in the lake ecosystems of the Bolshezemelskaya tundra (Nenets Autonomous Okrug, Russia). The purpose of this study was to evaluate and assess the levels, distribution characteristics and composition of organochlorines in the bottom sediments of small lakes located in the Adzva river basin in Pymvashor natural boundary (the northernmost location of the exit of thermal-mineral springs of the continental Europe) and in the adjacent area, outside this unique subarctic hydrothermal zone.In order to meet this goal, multi-method (hydrochemical, geochemical, etc.) research was carried out using standard generally approved laboratory practices with their adaptation to the study goals. The quantitative content and composition of the target individual organochlorines were determined by gas chromatographic method with electron-capture detection.The presence of chlorophenol compounds and polychlorinated benzenes (including persistent organic pollutants) was shown in the lakes sediments. The influence of specific microclimatic conditions of subarctic hydrothermal system on the composition and distribution of chlorophenol compounds in lake sediments was considered. In the small lake sediment core in Pymvashor natural boundary a reducing trend in the levels of organochlorines with depth has been recorded (conditioned among other things by the lithological features of bottom sediments). The chlorophenol compounds were found at highest concentrations (619.3–765.5 ng/g) in the sediment upper layers, rich in organic matter; chlorophenol composition was represented mainly by chlorinated phenols, most likely of biotic origin. A lower concentration (185.0 ng/g) of chlorophenol compounds of predominantly abiogenic origin was determined in the lake sediments outside hydrothermal system. The presence and levels of persistent organochlorine pollutants (pentachlorophenol 0.1–2.4 ng/g; hexa- and pentachlorobenzenes 0.4–3.6 ng/g) in the lake sediments were associated with long-range atmospheric transport from various origin sources in nearby regions and low-latitude territories.

Resumen
Effects of depression depth (ZT), lake surface elevation (ES), catchment area:lake surface area (AT:AO), trophic status, and surficial geology on sediment burial rates in small Western Boreal Plain lakes were assessed using content and chronology of cores from a relatively large and small lake on each of moraine (M), glaciofluvial (GF), and glaciolacustrine (GL) deposits. Aquatic and terrestrial plant and sediment carbon:nitrogen (C:N) suggested most buried C was aquatic. The rate of long-term total C burial averaged 31 g·m–2·year–1 (range: 0–84 g·m–2·year–1); this was recently 79 g·m–2·year–1 (range: 40–180 g·m–2·year–1) (higher and more variable rates than previously reported for Boreal lakes). Long-term C accrual rate and sediment depth increased with increasing ZT. In each landform, a relatively low base elevation (EB = ES – ZT) lake began accumulating sediment thousands of years before a high EB lake. GF depressions were deeper and had accrued more C·m–2 (and infilled) faster than M and GL lakes; a large GF lake had no organic sediment, perhaps because of large groundwater inputs. Increasing AT:AO corresponded with increasing C accrual rates where precipitation and evaporation dominated (surface runoff infrequent) (M and GL) but not where groundwater dominated (GF lakes) lake water budgets, illustrating the importance of landform and depression characteristics in regionalizing lake-C burial estimates.

This paper studies the diversity and distribution of Odonata (Insecta) in the South Urals region lakes such as Lake Large Miassovo, Lake Small Miassovo, Lake Ilmenskoe, Lake Savelkul and Lake Baraus. We revised dragonflies in five lakes during May-September 2014-2016. Dragonflies and larvae were identified up to the species. As results, 36 species (12 Zygoptera and 22 Anisoptera) belonging to 15 genera were recorded. To compare the similarities of dragonfly communities of different lakes we used the Canonical Correspondence Analysis (CCA) according the Jaccard index. Comparing the number of records of odonate species for selected lakes in our study, we found that the small richness of species was typical for lakes Savelkul and Baraus (22% and 25% of the total number of species, respectively) and the large values of the species richness was obtained for lakes Small Miassovo, Ilmenskoe and Large Miassovo (50%, 72%% and 80% of the total number of species, respectively).

Resumen
Despite lakes being a key part of the global water cycle and a crucial water resource, there is limited understanding of whether regional or lake-specific factors control water storage variations in small lakes. Here, we study groups of small, unregulated lakes in North Carolina, Washington, Illinois, and Wisconsin, USA using lake level measurements gathered by citizen scientists and lake surface area measurements from optical satellite imagery. We show the lake level measurements to be highly accurate when compared to automated gauges (mean absolute error = 1.6 cm). We compare variations in lake water storage between pairs of lakes within these four states. On average, water storage variations in lake pairs across all study regions are moderately positively correlated (ρ = 0.49) with substantial spread in the degree of correlation. The distance between lake pairs and the extent to which their changes in volume are correlated show a weak but statistically significant negative relationship. Our results indicate that, on regional scales, distance is not a primary factor governing lake water storage patterns, which suggests that other, perhaps lakes-specific, factors must also play important roles.

Resumen
ABSTRACT Small eukaryotes, cells with a diameter of less than 5 μm, are fundamental components of lacustrine planktonic systems. In this study, small-eukaryote diversity was determined by sequencing cloned 18S rRNA genes in three libraries from lakes of differing trophic status in the Massif Central, France: the oligotrophic Lake Godivelle, the oligomesotrophic Lake Pavin, and the eutrophic Lake Aydat. This analysis shows that the least diversified library was in the eutrophic lake (12 operational taxonomic units [OTUs]) and the most diversified was in the oligomesotrophic lake (26 OTUs). Certain groups were present in at least two ecosystems, while the others were specific to one lake on the sampling date. Cryptophyta, Chrysophyceae, and the strictly heterotrophic eukaryotes, Ciliophora and fungi, were identified in the three libraries. Among the small eukaryotes found only in two lakes, Choanoflagellida and environmental sequences (LKM11) were not detected in the eutrophic system whereas Cercozoa were confined to the oligomesotrophic and eutrophic lakes. Three OTUs, linked to the Perkinsozoa, were detected only in the Aydat library, where they represented 60% of the clones of the library. Chlorophyta and Haptophyta lineages were represented by a single clone and were present only in Godivelle and Pavin, respectively. Of the 127 clones studied, classical pigmented organisms (autotrophs and mixotrophs) represented only a low proportion regardless of the library's origin. This study shows that the small-eukaryote community composition may differ as a function of trophic status; certain lineages could be detected only in a single ecosystem.

Resumen
Small scale patchiness of phytoplankton biomass was the area around a single sampling station on a freshwater lake (Charnwood Water, Loughborough) between October l978 and October 1981. Patchiness in zooplankton and nutrients was also investigated. Data were initially examined by one-way analysis of variance in order to separate actual variation from measurement error. Nested analysis of variance models were used to examine the relative contributions of horizontal. vertical and diurnal variation and two-way analysis of variance was used to examine the importance of horizontal variation on the resolution of seasonal changes in phytoplankton biomass.

Texto completo
Resumen
The source of the pollen preserved within fossil assemblages is one of the most important factors to be considered when attempting to reconstruct fonner vegetation landscapes. Due to its mode of dispersal, at anyone time a pollen assemblage is a spatially aggregated record or pollen from local, extra-local and regional vegetation. Studies of pollen recruitment to lakes with surface inflows have shown that fluvial transport plays a dominant role in the recruitment of pollen to these sites. Pollen assemblage fonnation in lakes is further complicated by lirnnological processes which may affect the stratigraphic 'integrity' of the sediment record. A range of techniques and methodologies have been employed to investigate the influence of recruitment and lirnnological processes on the assemblage characteristics and pollen catchment area of an intennediate sized lake basin with surface inflows. The impact of land-use change OIi sediment yields and sediment sources has also been investigated through the use of mineral magnetic and sediment analytical techniques. The relative importance of aerial and streamborne recruitment has been established by , momtoring of pollen input to the lake from both sources over a 17 month period. Results , confmn the importance of fluvially transported pollen at this site and indicate that between 70-90% Qf the total pollen reaching the lake is derived via inflow streams at the present day. Downstream changes in the composition of streambome pollen caught in Tauber traps submerged within the main inflow stream suggests that at least 35% of the pollen recruited via the inflow is currently derived from 'local' riparian vegetation communities. Spatial and temporal patterns of intra-lake pollen deposition have been assessed by analysis and comparison of 24 surface lake mud samples and the pollen content of two parallel sediment cores. Central surface mud samples exhibit less 'noise' than those from marginal zones. Higher variability in littoral surface sediments, as measured by mean, standard deviation and coefficient of variation values of individual pollen types, is thought to reflect high deposition from lake marginal vegetation as well as limnological factors such as water turbulence. A greater diversity of pollen types were found in streamborne assemblages but in other respects percentages of the major pollen types in air, stream and surface lake samples were very similar. Comparison of the pollen, magnetic and sedimentological characteristics of parallel cores taken from the central lake area show close downcore strati graphic correspondence over the topmost 80cm. The shallowness of the lake does not appear to have produced any noticeable discontinuities or non-unifonn patterns of pollen and sediment deposition in central zones. . The effective pollen catchment area of the lake has been established by determining the 'sensitivity' of radiometrically dated lake pollen profiles to vegetation changes at different spatial scales within the landscape, established from documentary records of local and regional land-use and woodland history. From these data it is estimated that c. 70% of the pollen recruited to the lake originates from vegetation growing within c. 2.0 km of the lake. This conclusion contrasts with models of pollen recruitment proposed for similar sized lakes without inflow streams where a significant regional component (>60%) is predicted. Results suggests that the single largest contribution to total influx comes from stream marginal vegetation. A lakewide change in sediment type is recorded after Enclosure in 1789, as the focus of arable activity shifted from outside to inside the lake's drainage catchment. Mineral magnetic properties of lake sediment and catchment soils and sediments also indicate a shift in the source of allochthonous inputs reaching the lake at this time, from subsoil to topsoil derived material. Estimated inorganic sediment yields over the last 50 years are Iow when compared to similar sites with high lake/catchment ratios.

Resumen
The Heinrich- Martin Dam Impoundment (HMDI), located in northcentral LaMoure County, North Dakota, is an important water body for fishing, boating, and other recreational activities. To eliminate the thermal stratification and low dissolved oxygen (DO) zone near the bottom, an artificial aeration system was installed and operated by the North Dakota Game and Fish Department (NDG&F). This study was conducted to investigate whether aeration improved water quality of HMDI and to evaluate aeration as a tool to effectively manage eutrophication in lakes of this type. Field monitoring and laboratory analyses were conducted during three consecutive summers, in 2010, 2011 and 2012, to evaluate the impact of aeration on the spatial and temporal variation of physical, chemical, and biological water quality. Variables monitored included total and dissolved forms of inorganic nitrogen (N) and phosphorus (P), chlorophyll a, turbidity, water temperature and dissolved oxygen (DO). Field sampling was carried out during aerated conditions in 2010 and 2012 and under non-aerated conditions in 2011. The study revealed no significant differences between aeration and non-aeration conditions in soluble reactive phosphorus (SRP), total phosphorus (TP), or total nitrogen (TN) concentrations in the water column. In contrast, mean ammonia-nitrogen concentration at the near-bottom layers during non-aerated conditions decreased significantly under artificial aeration, while mean nitrate and nitrite concentrations increased significantly under aeration. Under aerated conditions, dissolved inorganic nutrients, TN, TP, temperature, and algae were homogenously distributed throughout the water column. Aeration expanded aerobic habitats for fish and distributed bio-available nutrients, stimulating algal growth throughout the water column. These results indicate that the existing aeration system vertically mixed nutrients throughout the water column of the HMDI. Chlorophyll a results showed that aeration distributed algae throughout the water column and circulated available nutrients for their growth. In addition, the results indicated that aeration improved water quality as measured by Secchi depth, turbidity, DO and algal biomass based on recommended levels by NDDoH. In a nitrogen-limited, phosphorus-rich water body, like HMDI, lowering phosphorus (P) load rather than nitrogen (N) load is recommended as a means of reducing algal biomass.

Resumen
Nonylphenol is a widely used organic compound which has been reported to have potential risk to aquatic environment. According to the result of recent studies, it has been detected in many lakes in Stockholm, Sweden, which raised great concern. In this thesis, a dynamic fate model was adopted and modified from literature in order to study the distribution and concentration of nonylphenol in small lakes, guide the field sampling and provide information for corresponding decision making. Two lakes in Stockholm, Lake Trekanten and Lake Drevviken, were selected as case studies. Another model was included for comparison purpose. Based on the model result, the most important nonylphenol removal process in both lakes was the transformation in water. A sensitivity analysis showed that the model results were most sensitive to the process of nonylphenol water inflow. In terms of sediment concentration of nonylphenol, satisfactory agreements were obtained from the comparison between model results and field data. However, problems, such as the simultaneous handling of nonylphenol and nonylphenol ethoxylates, may cause uncertainties on the model performance. The result of the analysis about scenario load change and the seasonal variation showed that the sediment nonylphenol content is more stable to the seasonal change compare to nonylphenol water content, but the response times to load change of nonylphenol content in these two compartments are quite close and somewhat lower than the water residence time.

Resumen
The purpose of this thesis is to evaluate whether the Territorial Use-Rights in Fishing (TURFs) of Lake Titieaca, Peru, are effective in overcoming the common property problem of typical fisheries and therefore whether TURFs may prove valuable as part of a more formal management system. It has recently been argued that TURFs should be incorporated into small-scale fisheries management schemes since they should be effective in controlling fishing effort, in promoting a more equitable distribution of the benefits from fishing and in reducing administrative inefficiencies. To determine whether TURFs are in fact effective in controlling fishing effort, I examine Lake Titieaca fisheries in Peru. First, I demonstrate the widespread existence of Lake Titicaca's TURFs and their control over the entire shoreline, most of the littoral area and even part of the pelagic area. Second, I document how, in spite of TURFs' illegality, Lake Titieaca shore dwellers are able to combine legal and illegal means to enforce their traditional rights over their fishing areas. Third, by showing that the relative difference between the returns to labour from fishing with those from alternative activities ranges from 50 to more than 100%, I demonstrate that local fishermen capture substantial fishing rents. If one takes into account that most fishing activities are carried out when there is little else to do, this range increases to 90-180%. I thus conclude that Lake Titieaca fisheries have not reached their bioeconomic equilibrium yet and that the predictions of the common property theory do not apply to them. And fourth, I demonstrate that the origins of these rents can be traced to fishermen's membership in TURF-holding communities, their ability to restrict physical access to the shoreline, and the obligations associated with this membership. Among these obligations are the participation in communal projects and celebrations, the fulfillment of administrative or ceremonial responsibilities, and the undertaking of agricultural activities, all of which constrain the amount of household labour available for fishing. In the concluding section, I consider the potential role of TURFs in a formal management context. I show that, in the long term, even formally recognized TURFs would not be sufficient in themselves to prevent overfishing. I therefore propose that Lake Titieaca TURFs be incorporated into a broader, decentralized management strategy which would capitalize on their strengths and promote cooperation between members of shore communities, fisheries scientists and administrators.

Resumen
The Engineer Research and Development Center, Information Technology Laboratory’s (ERDC-ITL’s) Big Data Analytics team specializes in the analysis of large-scale datasets with capabilities across four research areas that require vast amounts of data to inform and drive analysis: large-scale data governance, deep learning and machine learning, natural language processing, and automated data labeling. Unfortunately, data transfer between government organizations is a complex and time-consuming process requiring coordination of multiple parties across multiple offices and organizations. Past successes in large-scale data analytics have placed a significant demand on ERDC-ITL researchers, highlighting that few individuals fully understand how to successfully transfer data between government organizations; future project success therefore depends on a small group of individuals to efficiently execute a complicated process. The Big Data Analytics team set out to develop a standardized workflow for the transfer of large-scale datasets to ERDC-ITL, in part to educate peers and future collaborators on the process required to transfer datasets between government organizations. Researchers also aim to increase workflow efficiency while protecting data integrity. This report provides an overview of the created Data Lake Ecosystem Workflow by focusing on the six phases required to efficiently transfer large datasets to supercomputing resources located at ERDC-ITL.

Texto completo
Resumen
In the countries of the Lake Chad Basin, Boko Haram’s emergence has created major new security challenges for the region’s governments. Cameroon’s Far North region, the most populous in the country, is at the heart of these security issues. Since late 2020, Boko Haram has intensified attacks in Far North localities with assassinations targeting civilians, kidnappings, and looting in small towns along the Nigerian border. In response, the Cameroonian government has pursued a hardline strategy and militarized the affected localities. In addition to arbitrary arrests, prolonged pre-trial detention, prison overcrowding, and the death penalty are all sources of concern. This policy note outlines core findings from a case study of the Boko Haram ex-associates reintegration process in Cameroon. The note examines how existing community norms or mechanisms might be as useful as more standard approaches to disarmament, demobilization, and reintegration (DDR) in addressing challenges presented by Boko Haram ex-associates in Cameroon.

Texto completo
Resumen
Despite decades of interventions aiming to reduce child labour, children’s engagement with exploitative work remains widespread, particularly in South Asia. Emerging evidence about cash transfer programmes point towards their potential for reducing children’s engagement with work, but knowledge is scarce in terms of their impact on exploitative work and in urban settings. One component of the CLARISSA programme is to trial an innovative ‘cash plus’ intervention and to learn about its potential for reducing children’s harmful and hazardous work in two slum areas in Dhaka, Bangladesh. This Working Paper presents findings from a small-scale qualitative study that was undertaken in late 2019, aiming to inform the design of the cash plus intervention. Findings point towards the potential for cash transfers to reduce the need for children to engage in exploitative work and highlight key considerations for design and delivery, including mode and frequency of delivery and engagement with local leaders and community representatives.
