Abstract:
The purpose of this study was to investigate the link existing between inventory control strategies and supply chain viabilityusing downstream petroleum firms in Rivers State,Nigeria. This study adopted cross-sectional survey design. Questionnaires was the key instrument for data generation. The respondents were 134downstream petroleum staff in Rivers State. The study adoptedcensus since the population was not large, thus there was no need of sampling. Cronbach’s alpha test was adoptedto test the reliabilityof the instrument. The Pearson Moment Product Correlation Coefficient was used to test postulated hypotheses. The studyfinds out that,inventory control strategies significantly improve supply chain resilience and sustainable supply chain of downstream petroleum firms. Thus,by implementing inventory control strategies, thesefirms will improve their supply chain resilience and sustainable supply chain, and in turnthe attainable of their goal(s). It was recommended that, downstream petroleum firms should implement full inventory control strategies for effective and strong supply chain resilience and sustainable supply chain. Downstream petroleum firms should conduct regular assessment of their inventory control strategies in order to be updated with current realities for better supply chain resilience and sustainable supply chain.

Abstract:
It is widely accepted that firms can achieve effective inventory management with the right strategies. This study analyzed the inventory control strategies of small to medium-sized enterprises (SMEs) in Jamaica. The objectives of the study were to identify whether these companies used the “best practices” in inventory control, the effects of their strategies on business performance, and the factors that affected the development of their strategies. The study employed a methods triangulation approach that included case studies, interviews, questionnaires, and observation with a focus on twelve inventory-intensive SMEs in retail and manufacturing/distribution industries. The SMEs were found to use common inventory control strategies such as stock counts, Enterprise Resource Planning (ERP) systems, forecasting, and inventory classification.The findings of this study support institutional theory and isomorphism because it was discovered that due to external influences, firms studied within the same industry adopted similar strategies, and even in different industries, the ‘best practices’ in inventory control were the same. The drivers of this isomorphic organizational behavior were found to be costs, government regulations, and imitation of successful strategies in other companies. The SMEs surveyed were classified as semi-automated due to limited automation and confirmed success in their inventory management. The study validates the existence of institutionalism among SMEs in the retail as well as manufacturing/distribution industries in Jamaica. A broader scope examining larger firms and other industries would further identify isomorphic organizational behavior across the Jamaican business landscape. For future research, an investigation of financial performance and changes and adoption of new inventory control strategies of Jamaican SMEs is recommended to achieve a broad view of inventory management on the financial performance of Jamaican SMEs.

Abstract:
Despite using computerized merchandise control systems in retail, the rate of stockouts has remained stagnant. The inability to satisfy customer needs has caused a loss of 4% in potential revenue and resulted in dissatisfied customers. The purpose of this qualitative multiple case study was to explore cost-effective inventory control strategies used by discount retail managers. The conceptual framework that grounded the study was chaos theory, which helped identify why some business leaders rely on forecasting techniques or other cost-effective strategies as an attempt to prevent stockouts. The target population was comprised of discount retail managers located throughout northeast Jacksonville, Florida. Purposeful sampling led to selecting 6 retail managers who successfully demonstrated cost-effective inventory control strategies for mitigating stockouts. Data were collected through face-to-face semistructured interviews, company websites, and company documents. Analysis included using nodes to identify similar words and axial-coding to categorize the nodes into themes. Transcript evaluation, member checking, and methodological triangulation strengthened the credibility of the findings. Five themes emerged: (a) internal stockout reduction strategies, (b) external stockout reduction strategies, (c) replenishment system strategies, (d) inventory optimization strategies, and (e) best practices for inventory control. This study may contribute to positive social change by improving inventory management, which may reduce demand fluctuations in the supply chain and reduce logistics costs in the transportation of freight thereby leading to improved customer satisfaction.

Abstract:
Thesis (Ph. D.)--Massachusetts Institute of Technology, Sloan School of Management, Operations Research Center, 2003.<br>Includes bibliographical references (p. 127-130).<br>Traditional inventory models focus on effective replenishment strategies and typically assume that a commodity's price is exogenously determined. In recent years, however, a number of industries have used innovative pricing strategies to manage their inventory effectively. These developments call for models that integrate inventory control and pricing strategies. Such models are clearly important not only in the retail industry, where price-dependent demand plays an important role, but also in manufacturing environments in which production/distribution decisions can be complemented with pricing strategies to improve the firm's bottom line. To date, the literature has confined itself mainly to models with variable ordering costs but no fixed costs. Extending some of these models to include a fixed cost component is the main focus of this thesis. In this thesis, we start by analyzing a single product, periodic review joint inventory control and pricing model, and characterizing the structure of the optimal policy under various conditions. Specifically, for the finite horizon periodic review case, we show, by employing the classical k-convexity concept, that a simple policy, called (s, S, p), is optimal when the demand functions are additive. For the model with more general demand functions, we show that an (s, S, p) policy is not necessarily optimal. We introduce a new concept, the symmetric k-convex functions, and apply it to provide a characterization of the optimal policy. Surprisingly, in the infinite horizon periodic review case, the concept of symmetric k-convex functions allows us to show that a stationary (s, S, p) policy is optimal for both discounted and average profit models even for general demand functions.<br>(cont.) Our approach developed for the infinite horizon periodic review joint inventory control and pricing problem is then extended to a corresponding continuous review model. In this case, we prove that a stationary (s, S, p) policy is optimal under fairly general assumptions. Finally, the symmetric k-convexity concept developed in this thesis is employed to characterize the optimal policy for the stochastic cash balance problem.<br>by Xin Chen.<br>Ph.D.

Abstract:
The number of trips on highways and urban networks has significantly increased in the recent decades in many cities across the world. At the same time, the road network capacities have not kept up with this increase in travel demand. Urban road networks in many countries are severely congested, resulting in increased travel times, increased number of stops, unexpected delays, greater travel costs, inconvenience to drivers and passengers, increased air pollution and noise level, and increased number of traffic accidents. Expanding traffic network capacities by building more roads is extremely costly as well as environmentally damaging. More efficient usage of the existing supply is vital in order to sustain the growing travel demand. Travel Demand Management (TDM) techniques involving various strategies that increase the travel choices to the consumers have been proposed by the researchers, planners, and transportation professionals. TDM helps create a well balanced, less automobile dependent transportation system. In the past, several TDM strategies have been proposed and implemented in several cities around the world. All these TDM strategies, with very few exceptions, are static in nature. For example, in the case of congestion pricing, the toll schedules are previously set and are implemented on a daily basis. The amount of toll does not vary dynamically, with time of day and level of traffic on the highway (though the peak period tolls are different from the off-peak tolls, they are still static in the sense that the tolls don't vary continuously with time and level of traffic). The advent of Electronic Payment Systems (EPS), a branch of the Intelligent Transportation Systems (ITS), has made it possible for the planners and researchers to conceive of dynamic TDM strategies. Recently, few congestion pricing projects are beginning to adopt dynamic tolls that vary continuously with the time of day based on the level of traffic (e.g. I-15 value pricing in California). Dynamic TDM is a relatively new and unexplored topic and the future research attempts to provide answers to the following questions: 1) How to propose and model a Dynamic TDM strategy, 2) What are the advantages of Dynamic TDM strategies as compared to their Static counterparts, 3) What are the benefits and costs of implementing such strategies, 4) What are the travel impacts of implementing Dynamic TDM strategies, and 5) How equitable are the Dynamic TDM strategies as compared to their Static counterparts. This dissertation attempts to address question 1 in detail and deal with the remaining questions to the extent possible, as questions 2, 3, 4, and 5, can be best answered only after some real life implementation of the proposed Dynamic TDM strategies. Two novel Dynamic TDM strategies are proposed and modeled in this dissertation -- a) Dynamic Congestion Pricing and b) Dynamic Highway Space Inventory Control System. In the first part, dynamic congestion pricing, a real-time road pricing system in the case of a two-link parallel network is proposed and modeled. The system that is based on a combination of Dynamic Programming and Neural Networks makes "on-line" decisions about road toll values. In the first phase of the proposed model, the best road toll sequences during certain time period are calculated off-line for many different patterns of vehicle arrivals. These toll sequences are computed using Dynamic Programming approach. In the second phase, learning from vehicle arrival patterns and the corresponding optimal toll sequences, neural network is trained. The results obtained during on-line tests are close to the best solution obtained off-line assuming that the arrival pattern is known. Highway Space Inventory Control System (HSICS), a relatively new demand management concept, is proposed and modeled in the second half of this dissertation. The basic idea of HSICS is that all road users have to make reservations in advance to enter the highway. The system allows highway operators to make real-time decisions whether to accept or reject travellers' requests to use the highway system in order to achieve certain system-wide objectives. The proposed HSICS model consists of two modules -- Highway Allocation System (HAS) and the Highway Reservation System (HRS). The HAS is an off-line module and determines the maximum number of trips from each user class (categorized based on time of departure, vehicle type, vehicle occupancy, and trip distance) to be accepted by the system given a pre-defined demand. It develops the optimal highway allocations for different traffic scenarios. The "traffic scenarios-optimal allocations" data obtained in this way enables the development of HRS. The HRS module operates in the on-line mode to determine whether a request to make a trip between certain origin-destination pair in certain time interval is accepted or rejected.<br>Ph. D.

Thereafter the production of sea salt started to be made in a process of continuous flow, where the product is constantly stored in yards, with daily movements in and out of salt. Thus far, the major bottleneck found in this production process is the control of production, because due to the large amount produced and variety of losses existing in the various stages of production there are not a regulated and safe way to control inventories with accuracy and speed demanded. In a typical case with a salt marsh company of Rio Grande do Norte state, salt produced is stored in two open courtyards and inventory control of salt made by carrying input / output relationship of salt in each storage yard. This work developed a conceptual model of inventory control, based on topography, adopting surveys into one of the courtyards of the company. There were 25 biweekly survey measurements over a year book to generate digital models representing the stock. For each measurement, results were compared with the values of inventory accounting provided by the salt marsh in order to identify existing losses and mark out the sales department on the actual stock available at each measurement date. Inventories calculated by the model indicated losses of 6,349 tonnes for the period of one year book and 3,279 tonnes for the period between harvests, when compared to the accounting control<br>O fortalecimento da ind?stria nacional nos ?ltimos 20 anos exigiu a moderniza??o, mecaniza??o e amplia??o da produ??o salineira.

Abstract:
This chapter emphasizes the key elements required to implement supply chain strategy in a firm. It highlights the differences in supply chain strategies, its alignment with corporate strategies, and the associated drivers of supply chain management. This chapter also highlights the dynamics associated with inventory and success of supply chain of a firm. It tries to provide a framework to resolve the supply chain managers' dilemma as to hold inventory for order fulfilment or to enhance the inventory turnover ratio to maximize profitability. The chapter discusses all facets of inventory management – it includes inventory management of constant as well as dynamic demand. This chapter introduces the concept of adaptive inventory control for non-stationary demand. There are situations when all assumptions of conventional approach may fail and hence points out the importance of application of artificial intelligence and data science in inventory management. This chapter brings out the varied dimensions of contracts that are crucial to have an effective supply chain system. Here the author attempts to put forward an outsourcing decision framework to facilitate make or buy decision. This chapter relates the concept of materials requirement planning (MRP) with independent items. Since supply chains are going global, this chapter introduces the concepts behind global sourcing including the significance of INCO (international commercial) terms.

Abstract:
India's quick service restaurant market has expanded significantly in recent years. For small-scale QSRs, inventory management continues to be an essential challenge. Inventory management enhances the efficiency of business operations by influencing the stockpile and supply of essential products and materials. The research aims to highlight the importance of inventory control and management in QSRs. Primary data was collected from 120 operational QSRs in Bangalore in Karnataka and 30 from Kottayam in Kerala. It was found that most of the respondents felt that proper inventory management and control could help to improve their service quality and help to reduce costs. It has been found that the factors service, savings, and risk have a strong positive correlation with inventory cost. Several techniques and strategies like techniques for cooking with no waste, menu planning with fewer ingredients, networks for local sourcing, matching demand and supply through seasonal planning have been identified to increase the performance of QSRs.

Abstract:
Inventory management is pivotal for business performance and profitability. Efficiently handling inventory levels enhances operational efficiency and financial strategies. Poor management can result in financial losses, stock imbalances, delayed order fulfillment, and dissatisfied customers. This chapter discusses inventory management frameworks, focusing on objectives, techniques, and best practices. The primary goal is to balance overstocking and understocking, ensuring adequate working capital while optimizing costs. The chapter delves into various inventory management techniques, aiming to effectively control and manage inventory. It particularly sheds light on two pivotal techniques: Vendor-Managed Inventory (VMI) and Just-in-Time (JIT). VMI reduces inventory levels and improves fill rates, enhancing supply chain performance. On the other hand, JIT minimizes excess inventory and improves material flow. Both techniques present challenges and benefits.

Abstract:
This chapter focuses on materials and inventory performance. It explores inventory management and the different types of inventory: raw materials, work in process, finished goods, cycle, buffer, anticipation, and pipeline inventories. The chapter highlights the importance of keeping an inventory, as demand is not always predictable. It then notes inventory management as the planning and controlling of inventories in order to meet the competitive priorities of the operation. In addition, the chapter explores the strategies in materials management, production planning, and control systems. It also narrates the developments in inventory management by referencing just-in-time, radio frequency identification, and electronic data interchange.

Abstract:
Abstract The small mobile nuclear power system using the HeXe Brayton cycle as its energy conversion system has promising application potential. Among the research, control strategies get a lot of attention, which makes variable operation of the system possible. Among various control strategies, inventory control is widely used in the load-following process as it enables the system to remain high efficiency during load regulation. However, compared to other control strategies, it has a slower response time, which needs to be improved. In this study, a one-dimensional dynamic model of a simple HeXe close Brayton cycle reactor power conversion system, as well as its main equipment, has been proposed. Focusing on inventory control, the effects of initial tank volume and pressure on load range that the control strategy could meet were investigated. The open loop simulation of coolant mass in the loop was carried out. After that, to overcome its disadvantage, inventory control has been modified for rapid load regulation by combining with valves, so that the optimized inventory control method could meet the rapid load change process while maintaining high efficiency and safe operation of the system.

Abstract:
In the context of large-scale hydrogen energy utilization for power generation, the R-Graz cycle has demonstrated remarkable performance and technological feasibility. To meet the requirements of grid supply, it is imperative to develop appropriate control strategies to achieve stable and efficient operation. In addition to the conventional control parameters such as fuel and IGV adjustments, there exists an additional control parameter called split ratio. In this study, various control strategies were formulated and performance analyses were conducted for the R-Graz cycle. The results indicate that the control strategy aiming to maintain the turbine inlet temperature outperforms the strategy aiming to maintain the exhaust temperature in terms of efficiency. Within the control strategy focused on maintaining the turbine inlet temperature, the inventory control strategy demonstrates superior efficiency compared to the split ratio and IGV control strategies. By integrating the advantages of various control strategies, a hybrid inventory control strategy suitable for the R-Graz cycle is proposed. At 40% load, the efficiency is about 87.1% of the design point, surpassing conventional F-class combined cycle units.

Abstract:
Abstract High-temperature heat pumps (HTHPs) are becoming increasingly relevant in the industry as they represent a promising solution for decarbonising industrial heat. These technologies can enable the electrification of industrial processes by exploiting electricity from renewables to provide process heat at temperatures above 250 °C, as in the case of emerging Brayton-based HTHPs. To succeed in this purpose, HTHPs must also ensure operational flexibility, which entails the ability to operate safely under varying loads and promptly respond to fluctuations in demand, while maintaining high efficiencies. Moreover, the ability to provide large flexible electric loads to transmission system operators, has the potential to unlock innovative business cases and further promote the use of these systems. Common control strategies for achieving this, include employing bypass mechanisms, fluid inventory control, and adjusting turbomachinery rotational speeds. Despite their variety, the simultaneous use of such control strategies is often limited as they may lead to significantly different system behaviours, both in terms of transient and steady performance. In this paper, rotational speed and fluid inventory control are examined from a transient perspective to maintain the desired sink temperature while regulating the thermal load of the system. Results indicate that rotational speed control leads to negligible sink temperature residuals, while fluid inventory control better preserves the HTHP performances for varying temperature glides.

Abstract:
This paper considers a modular product assembly and inventory planning and control problem in a remanufacturing environment. The return process of end-of-life product is a stochastic process in terms of arriving time, quality and quantity. We investigate the returned module reassembly policies in an assemble-to-order strategy. A threshold policy is considered to control the admission of the product returns and its effect on the trade-off between excessive inventory and stock out. We study how the control parameters in these strategies relate to the average inventory level and stock out level of the remanufacturable modules. Starting with a single quality grade problem, we extend the analysis to a multiple quality grade problem and derive exact expression of the system performance measures as function of the control parameters. Main objective of this paper is to provide managerial insights into decision-making for stochastic remanufacturing systems.

Abstract:
New infectious diseases, especially one of the magnitudes of COVID-19, leads to complex situations for individuals and communities alike. Particularly in higher education, learners faced a surrealist world in which education shifted abruptly to an online setting because of the virus. Regardless of their field of study, they had to apply coping strategies to adapt and incorporate new values, beliefs, and perspectives into a new learning environment. Universities must foster educational opportunities to train learners on these capacities to prepare professionals for their success in their profession. This study’s objective was to assess these adaptability strategies that higher-education learners had to tackle the uncertainty of the coronavirus pandemic. A quantitative approach was considered with a descriptive and cross-sectional design. The convenience sample consisted of 34 learners in the final year of their medical program. As an instrument, an adaptation of the Proactive Coping Inventory was used with a 5-level Likert scale where 1 stands for total disagreement and 5 with total agreement. According to the results, students use more than one strategy to cope with difficult situations. The mean obtained in the control strategy was 3.98, curiosity 3.18, confidence 3.02, and concern was 2.97. The ANOVA test showed that there is no significant difference in the dimensions (p-value of 0.062). These results indicate that students had the intellectual curiosity to propose new personal and professional development goals and monitor the scope of those through selfregulation. Institutions need to learn from what they implemented amid the pandemic and incorporate best practices for the new normality ahead.

Abstract:
The objectives of this research are (1) to assemble and analyze commercial vehicle emission measurement data, (2) classify the effects of vehicle characteristics and traffic activities on commercial vehicle emissions, (3) estimate commercial vehicle emissions statewide in Illinois, and (4) identify truck emission-control strategies with a focus on truck electrification feasibility. The study found that vehicle type, make, age, odometer mileage, fuel type, engine brand (manufacturer), and engine built year are all important factors for truck emissions, and their effects are statistically significant according to ANOVA results. All pollutant emissions (CO, NOx, PM10, PM2.5, CO2) other than CH4 have a downward trend from 2019 to 2021 in Illinois. Such emission trends may be explained by a shift from long-distance truck trips to more regional and local trips between 2019 and 2021. Prolonged journey time due to charging and high initial adoption cost remain deterrents for long-haul e-truck adoption by carriers. Therefore, government policy plays a key role in facilitating electrification.

Full text
Abstract:
The War in the Pacific National Historical Park (WAPA), a protected area managed by the National Park Service (NPS), was established "to commemorate the bravery and sacrifice of those participating in the campaigns of the Pacific Theater of World War II and to conserve and interpret outstanding natural, scenic, and historic values on the island of Guam." Coral reef systems present in the park represent a vital element of Guam?s cultural, traditional, and economical heritage, and as such, are precious and in need of conservation. To facilitate the management of these resources, NPS determined that a scleractinian (stony coral) species survey was necessary to establish a baseline for existing coral communities and other important factors for conservation. EnviroScience, Inc. performed a survey of stony coral species, coral habitat, and current evidence of stressors at WAPA?s H?gat and Asan Units in 2022. This report summarizes these findings from a management perspective and compares its findings to previous survey data from 1977 and 1999 (Eldridge et al. 1977; Amesbury et al. 1999). WAPA is located on the tropical island of Guam, located on the west-central coast of the island, and encompasses 2,037 acres. Underwater resources are a significant component of the park, as 1,002 acres consists of water acres. The park is comprised of seven units, of which two of these, the H?gat and Asan Beach Units, include all the oceanic water acres for the park. The H?gat Beach Unit (local spelling, formerly known as ?Agat?) is located at the south-west portion of the park and consists of 38 land acres and 557 water acres (NPS 2003). The Asan Beach Unit consists of 109 acres of land and 445 water acres (NPS 2003). A current baseline for existing coral communities and other important factors for conservation necessitates the need for up-to-date data on the location, presence, relative abundance, and present health of corals. Park managers need this updated data to determine where and how to best focus conservation priorities and identify restoration opportunities. Management actions in park reef areas informed by this inventory included identifying locations where there were: high rates of sedimentation; high coral biomass; rare or threatened species, with a priority given to species endemic to Guam and listed as ?threatened? under the U.S. Endangered Species Act (ESA; Acropora globiceps, A. retusa, A. speciosa, and Seriatopora aculeata); coral persistence and decline, disease and/or nuisance species, including the crown-of-thorns starfish (Acanthaster cf. solaris, ?COTS?) and the sponge Terpios hoshinota; and bleached areas. All work carried out was in accordance with the NPS statement of work (SOW) requirements, which involved a quantitative inventory using both new and pre-existing transects. The resulting transects totaled 61 (including the four from the 1999 study), each measuring 50 meters in length and distributed across depths of up to 50 feet. Divers took photo-quadrat samples covering an area of approximately 9 m?, encompassing 50 photo-quadrats of dimensions 0.50 m x 0.36 m (n=50). The collective area surveyed across all 61 transects amounted to ~549 m?. Additionally, a qualitative search was conducted to enhance documentation of coral species that have limited distribution and might not be captured by transects, along with identifying harmful species and stressors. Timed roving diver coral diversity surveys were carried out at a total of 20 sites occurring within the waters of WAPA, including eight sites at the H?gat unit and 12 sites at the Asan unit. The findings from this report reveal significant disparities in benthic cover compositions between H?gat and Asan units. The H?gat unit exhibits high abundances of turf algae and unconsolidated sediment while the Asan beach unit presents a different scenario, with hard coral as the dominant benthic cover, followed closely by crustose coralline algae (CCA). The Asan unit is also more difficult to access from shore or boat relative to H?gat which provides that unit some protection from human influences. The Asan beach unit's prevalence of hard coral, CCA, and colonizable substrate suggests a more favorable environment for reef growth and the potential benefits of maintaining robust coral cover in the area. These distinct differences in benthic communities highlight the contrasting ecological dynamics and habitats of the two study areas. Across both H?gat and Asan beach unit transects, a total of 56 hard coral species were recorded from 27 genera, with 44 species recorded from the H?gat unit and 48 species recorded from the Asan unit. Of the four historical transects surveyed in the Asan unit from 1999, three experienced declines in percent coral cover (17.38-78.72%), while the fourth had an increase (10.98%). During the timed roving diver coral diversity surveys, a total of 245 hard coral species, including 241 scleractinian coral species representing 49 genera and 4 non-scleractinian coral species representing 4 genera were recorded. Uncertainties related to coral identification, unresolved boundaries between morphospecies, differences in taxonomists' perspectives, and the rapidly evolving state of coral taxonomy have significant implications for species determinations during coral diversity surveys. While the recent surveys have provided valuable insights into coral diversity in WAPA waters, ongoing taxonomic research and collaboration among experts will be essential to obtain a more comprehensive and accurate understanding of coral biodiversity in the region. Of the several ESA coral species that were searched for among the H?gat and Asan beach units, Acropora retusa was the only coral species found among quantitative transects (n=2) and A. globiceps was observed during coral diversity surveys. Acropora speciosa, which was dominant in the upper seaward slopes in 1977, is now conspicuously absent from all the surveys conducted in 2022 (Eldredge et al., 1977). The disappearance and reduction of these once-dominant species underscores the urgency of implementing conservation measures to safeguard the delicate balance of Guam's coral reefs and preserve the diversity and ecological integrity of these invaluable marine ecosystems. Other formerly common or locally abundant species were infrequently encountered during the diversity surveys, including Acropora monticulosa, A. sp. ?obtusicaulis?, A. palmerae, Stylophora sp. ?mordax?, Montipora sp. ?pagoensis?, and Millepora dichotoma. Significant bleaching-associated mortality was recorded for these species, most of which are restricted to reef front/margin zones exposed to moderate-to-high levels of wave energy. Sedimentation was present in both H?gat and the Asan units, though it was more commonly encountered in H?gat transects. While significant portions of the reef area within the WAPA H?gat unit are in poor condition due to a variety of stressors, some areas still hosted notable coral communities, which should be a potential focus for park management to prevent further degradation. There is a need for more effective management of point source pollution concerns, particularly when subpar wastewater treatment or runoff from areas with potential pollution or sediment-laden water is flowing from nearby terrestrial environments. Future monitoring efforts should aim to establish a framework that facilitates a deeper understanding of potential point source pollution incidents. This would empower park managers to collaborate with adjacent communities, both within and outside of park boundaries, to mitigate the localized impacts of pollution (McCutcheon and McKenna, 2021). COTS were encountered during transect surveys as well as in coral diversity surveys. including along the upper reef front/reef margin at site Agat-CS-2. The frequency of these observations, particularly in the WAPA H?gat unit and where stress-susceptible corals are already uncommonly encountered, raise concern about the ability of the populations of these coral species to recover following acute disturbance events, and calls in to question the ability of some of these species to persist in WAPA waters, and in Guam?s waters more broadly. More frequent crown-of-thorns control efforts, even if only a handful of sea stars are removed during a single effort, may be required to prevent further loss to vulnerable species. There were several documented incidents of Terpios hoshinota covering large sections of branching coral in the reef flat along transects, but it is still unclear how detrimental this sponge is to the overall reef system. There is a concern that elevated levels of organic matter and nutrients in the water, such as those resulting from sewage discharge or stormwater runoff, could lead to increased Terpios populations (De Voogd et al. 2013). Consequently, it is important to track populations in known areas of sedimentation and poor water quality. The presence of unique species at single survey sites within the study areas underscores the ecological importance of certain locations. Some species are known to occur in other locations in Guam, while a few may be limited to specific sites within WAPA waters. These differences are likely influenced by environmental and biological factors such as poor water quality, severe heat stress events, chronic predation by crown-of-thorns sea stars, disease, and reduced herbivore populations. These factors collectively shape the condition of the benthic community, leading to variations in species distribution and abundance across the study sites. Documenting coral stress and identifying potentially harmful species allows for proactive management strategies to prevent the establishment of nuisance or detrimental species while populations are still manageable. Updated data on the location, presence, relative abundance, and health of corals is essential for park managers to prioritize conservation efforts and identify restoration opportunities effectively. Observations from this report raise concerns about the health and resilience of coral ecosystems in the H?gat unit and emphasize the need for knowledge of local factors that shape benthic community structure. Understanding the drivers responsible for these variations is crucial for effective conservation and management strategies to preserve the ecological balance and overall health of coral reefs in both units. Continued monitoring efforts will be critical in assessing long-term trends and changes in benthic cover and enabling adaptive management approaches to safeguard these valuable marine ecosystems in the face of ongoing environmental challenges.

Abstract:
Managers are challenged with the impact of problematic plants, including exotic, invasive, and pest plant species. Information on the cover and frequency of these plant species is essential for developing risk-based approaches to managing them. Based on surveys conducted in 2006, 2013, 2018, and 2021, Heartland Inventory and Monitoring Network staff and contractors identified a cumulative total of 38 potentially problematic plant species in Pea Ridge National Military Park. Of the 35 species found in 2021, we characterized 13 as very low frequency, 9 as low frequency, 9 as medium frequency, and 4 as high frequency. Of these 35 species, midpoint cover estimates of 4 medium frequency and all 4 high frequency species exceeded the 10-acre threshold. The 10-acre threshold represents a limit beyond which eradication of a problematic plant species is likely not possible. Clearing of eastern redcedar (Juniperus virginiana) continues to be evident in our observations, and sericea lespedeza (Lespedeza cuneata) appears to have increased as clearing progressed. The rapid increase in Japanese stiltgrass (Microstegium vimineum) appears to be parkwide. Because of the number, extent, and cover of problematic plants in the park, control efforts should focus on early detection treatments and strategic treatment of high priority, widespread species to protect features of the park’s natural and cultural landscapes. High priority species may include plant species capable of rapid spread, species at low population levels, and species that can be effectively controlled.
