Abstract:

Abstract The uprising alternately called EDSA Revolution or People Power Revolution or EDSA People Power Revolt, which led to the downfall of Filipino dictator Ferdinand Marcos in 1986, supposedly ushered in the formal restoration of civil freedoms that had been snatched away by Marcos’ martial law. In the aftermath of the uprising, formal democratic institutions and civil rights were returned, including the right to free elections and the right to peaceful assembly. But as this article seeks to show, the administrations after EDSA have been marred by the neglect of workers’ welfare and the failure to address old labor concerns such as inadequate wages, job precarity, and contractualization. Given the shortage of employment opportunities in the Philippines, the administrations after EDSA have also promoted migration as its de facto job-generating mechanism. But the export of human resources is not without its ugly consequences, such as making overseas Filipino workers (OFWs) susceptible to abuse and exploitation. Deploying the notion of counter-history and using various materials from both government and non-government organizations, this article undertakes to critically assess the labor conditions during the historical period after the fabled EDSA People Power Revolt, and concludes that no notable changes have taken place.

Abstract:

Does talking about the triumph of the 1986 People Power EDSA Revolution still make sense nowadays? When the ideals of this glorious revolution are now nothing but contents of Philippine history textbooks and items of the culture industry, do we still need to re-imagine it? These are some of the reflective questions that will challenge and guide this paper‟s architecture. In what follows, the author will push all the possibilities for a Nietzschean re- thinking of the EDSA Revolution as “ the experience of difference and an exemplar of ascending life. ” In the first part, an account of the nature of EDSA revolution will be illustrated; while in the second, the principle of the „ Will to Power ‟ and „ Eternal Return ‟ will be explained using Gille s Deleuze‟s rhizomatic eyeglasses. In the third, the narrative of the revolution, i.e., the process on how the Epifanio Delos Santo Avenue (EDSA) turned into an arena for collective-political action will be delineated. Furthermore, the concept of difference will be utilized in explaining the dynamic occurrences produced by the Dionysian assemblage of Filipino bodies. In the last, the challenge of a different return of the said revolution will be explained.

Abstract:

The general framework of the bottom-up approach for modeling mobile emissions and energy use involves the following major components: (1) quantifying traffic flow and (2) calculating emission and energy consumption factors. In most cases, researchers deal with complex and arduous tasks, especially when conducting actual surveys in order to calculate traffic flow. In this regard, the authors are introducing a novel method in estimating mobile emissions and energy use from road traffic flow utilizing crowdsourced data from Google Maps. The method was applied on a major highway in the Philippines commonly known as EDSA. Results showed that a total of 370,855 vehicles traveled along EDSA on average per day in June 2019. In comparison to a government survey, only an 8.63% error was found with respect to the total vehicle count. However, the approximation error can be further reduced to 4.63% if cars and utility vehicles are combined into one vehicle category. The study concludes by providing the limitations and opportunities for future work of the proposed methodology.

Abstract:

This study examines how nine children’s stories which won awards in the Don Carlos Palanca Memorial Awards for Literature in the English category portray and shape children’s view of themselves, their peers, family, community and the world. Using Marxism, Gender, Race and Ethnic Studies as its theoretical framework, the study reveals that the stories underscore the differences in gender roles, institutionalize the school and community as sites for learning and hegemony, contextualize decision making and ethnic identity and expose the vulnerability of women and children as reserved labor force. Furthermore, the child heroes are active participants in their respective social circles and are often enjoined to carry out adult responsibilities such as taking care of a sibling and saving a community. This paper concludes that children’s literature, specifically stories, have powerful influences in shaping the child’s conceptions of his or her sexuality, class consciousness and multiple roles as member of the family, community, and the state.Keywords: Children’s literature, family, gender roles, Post-Edsa II, sexualityCite as: Majul, M.A.M.

Abstract:

The power plant with renewable energy sources is needed to reduce the pollution. One of this kind is in Bali, that is PLTSa (Garbage Power Plant) Suwung. However, PLTSa Suwung is no longer operating for now. PLTSa Suwung is connected with Serangan feeder, this connection named Distributed Generation. When PLTSa Suwung doesn’t operate, it will affect the Serangan feeder’s voltage profile. The change of voltage profile will be analyzed with EDSA Technical 2000 Service Pack 3.5 software. The research will give five scenarios with different electrical power supply from each scenario. The gap of the voltage profile between scenario 1 (100% power supply from PLTSa) and scenario 5 (0% power suplly from PLTSa) is 0,0079% for medium voltage bus and 0,0062% for low voltage bus. This small gap shows that the connected PLTSa Suwung doesn’t give effect to voltage profile of Serangan feeder.

Abstract:

Abstract. When it comes to business and marketing, huge outdoor advertising is considered as one of the best ways by contributing largely in disseminating information about a product, service or even raise awareness. With commuters or the people riding in a moving car as its target audience, the placement of advertising materials is very crucial since it should be visible and must deliver its message in a short span of time. This study tests the methodology of gathering data using action camera and DSLR mounted and situated on a moving vehicle, utilizing structure from motion techniques, to extract the geometry of the billboards from the point cloud generated from structure-from-motion as acquired from camera videos that would be used to represent these billboards in the three-dimensional space. These extracted geometries would be used for visibility analysis from a passenger’s point of view by assessing the percentage of visible content and logos of each billboard from each point of observation along the path of a moving vehicle. The results of this study are nine sets of mean percent visibilities and raster representations that show the mean percent visibility of the billboards as viewed from the road of interest. To assess product placement effectiveness of the billboards, visibility percentage of the product logos contained in the nine billboards was also obtained.

Abstract:

We analyzed the susceptibility of Arabidopsis mutants with defects in salicylic acid (SA) and jasmonic acid (JA)/ethylene (ET) signaling to infection by Cauliflower mosaic virus (CaMV). Mutants cpr1-1 and cpr5-2, in which SA-dependent defense signaling is activated constitutively, were substantially more resistant than the wild type to systemic infection, implicating SA signaling in defense against CaMV. However, SA-deficient NahG, sid2-2, eds5-1, and pad4-1 did not show enhanced susceptibility. A cpr5 eds5 double mutant also was resistant, suggesting that resistance in cpr5 may function partially independently of SA. Treatment of cpr5 and cpr5 eds5, but not cpr1, with salicyl-hydroxamic acid, an inhibitor of alternative oxidase, partially restored susceptibility to wild-type levels. Mutants etr1-1, etr1-3, and ein2-1, and two mutants with lesions in ET/JA-mediated defense, eds4 and eds8, also showed reduced virus susceptibility, demonstrating that ET-dependent responses also play a role in susceptibility. We used a green fluorescent protein (GFP)-expressing CaMV recombinant to monitor virus movement. In mutants with reduced susceptibility, cpr1-1, cpr5-2, and etr1-1, CaMV-GFP formed local lesions similar to the wild type, but systemic spread was almost completely absent in cpr1 and cpr5 and was substantially reduced in etr1-1. Thus, mutations with enhanced systemic acquired resistance or compromised ET signaling show diminished long-distance virus movement.

Abstract:

Since the late 1980s, Filipino entertainment television has assumed and maintained a dominance in national popular culture, which expanded in the digital era. The media landscape into which digital technologies were launched in the Philippines was largely set in the wake of the 1986 popular movement and change of government referred to as the EDSA revolution: television stations that had been sequestered under martial law were turned over to family-dominated commercial enterprises, and entertainment media proliferated. Building upon the long development of entertainment industries in the Philippines, new social media encounters with entertainment content generate expanded and engaged publics whose formation continues to operate upon a foundation of televisual media. This article considers the particular role that entertainment media plays in the formation of publics in which comedic, melodramatic and celebrity-led content generates networks of followers, users and viewers whose loyalty produces various forms of capital, including in notable cases political capital.

Abstract:

AbstractThe subject of this paper is the politics of 'use' and 'misuse' of religious iconography during popular uprisings in the Philippines. It will discuss the ways in which religious icons, specifically the Santo Niño and Our Lady of EDSA, are co-opted for specific political and social agendas. "Rebellion" is broadly defined here as the combined action of a large group of people against what they see as the oppressive and hegemonic force that prevents the full enactment of their common interest. The concern here is to describe how mass action incorporates the imagery of divine personages so that revolutions are, simultaneously, acts of worship and rebellion. This paper asks the following question: What are the processes by which religious iconographies contextualise rebellion in the Philippines? What are the circumstances that led to a repetition of such events throughout the history of the country? And finally, under whose authority are rebellions and protests in the Philippines labelled and packaged as 'holy' and 'divine'? This paper will argue that the 'holiness' of religiously inspired mass uprisings is contingent upon specific acts of legitimisation, 'packaging' and semantic contestation.

Abstract:

En la literatura hay una falta de investigación acerca de las desigualdades en salud en Sudamérica y sus diferencias con respecto a las de los países desarrollados. Como en Italia se han registrado tendencias similares en los últimos años y muestra similaridades con la Argentina, se ha decidido utilizar el país mediterráneo con fines comparativos. La hipótesis planteada consistió en que, más allá de las diferencias estructurales, las desigualdades en salud presentarían patrones similares en ambos países, caracterizados por una economía capitalista. Los grupos sociales en posiciones educativas y ocupacionales favorables exhibirían un mejor estado de salud que los grupos desfavorecidos. Se presentaron algunas estadísticas descriptivas sobre la situación general en los dos países, y luego se analizaron datos provenientes de dos encuestas que recolectan información individual sobre condiciones sociales y estados de salud (EDSA, de 2017 a 2018, y “EHIS - European Health Interview Survey”, ISTAT, 2015). Los resultados muestran que la Argentina e Italia poseen diferentes niveles de bienestar, tasa de mortalidad y servicios de salud, pero que las disparidades relativas en salud parecen muy similares, confirmando la hipótesis de Marmot (2017) sobre la forma general de las desigualdades en salud. Trabajadores manuales y precarios, particularmente las personas desempleadas, sistemáticamente presentan un peor estado de salud percibido con respecto a las clases sociales más altas.

Abstract:

While the organization of the Philippine sugar industry evolved to promote and balance the short-term interests of planters, millers and traders, it now undermines the industry and threatens the economic fortunes of those who depend upon it. By perpetuating inefficiency and fostering a frenzy of trading that affords inordinate profits for the least productive sector, this structure has become the major obstacle to restoring the Philippines to its former status as one of the world's most efficient and technologically advanced producers of cane sugar. As efficiency falls further behind that of other sugar producing countries, and as industrial consumers become more disgruntled with paying high prices for sugar, the nation risks the collapse of an industry that has already proven vulnerable to intermittent crises. The last time a crisis occurred — in the mid-1980s — planters faced foreclosure, mills stood idle, and workers and their families suffered malnutrition and dislocation, leading commentators to refer to Negros, the nation's premier sugar-growing island, as “Asia's Ethiopia” and a “social volcano”. While conditions have improved since the EDSA Revolution, the structure that has emerged does little to encourage productivity, efficiency and fairness. Since the industry continues to employ 500,000 workers, with as many as three million dependents, a collapse would lead to mass displacement, hunger, and political upheaval.This paper will outline the history of the Philippine sugar industry, examine its current structure, and describe the political and economic forces that sustain it. My first contention is that the institutional organization, rather than government policy, cultural attitudes, or neo-colonial dependency, is fundamentally responsible for the poor performance of the industry in recent decades and, unless major changes are forthcoming, will be mainly responsible for its ultimate demise.

Abstract:

CoVID-19 pandemic forced a countrywide lockdown in the Philippines from March 16, 2020 to May 15, 2020 and extended to May 31, 2020 in Metro Manila and some parts of Central Luzon. Because of these forced restrictions, the air pollution level in Metro Manila drastically slowed down just a few weeks upon the implementation of the lockdown. Therefore, this study aimed to establish a preliminary case review on the implications of the lockdown to the air quality in the country’s capital with the aid of data from the Centre for Research on Energy and Clean Air (CREA) and Airtoday.ph station. The empirical analysis revealed that when Metro Manila was under Enhanced Community Quarantine (ECQ), tropospheric nitrogen oxide (NO2) dropped by approximately 52% compared to the 2019 levels in the same period. The city also registered the lowest PM 2.5 air pollution levels during the first 30 days of the lockdown with an average of 11.59 ug/m3. Moreover, the satellite image from the Institute of Environmental Science and Meteorology (IESM), UP Diliman showed a lower Atmospheric Optical Depth (AOD) of 0.01, which means that the air is clean during the lockdown period when compared with the AOD value during the same period in 2018 and 2019. At the Lung Center of the Philippines, a comparison of pre-ECQ and ECQ air quality levels showed that PM2.5 is reduced from 80% to 180%, particularly during evenings and early mornings. A similar trend along EDSA Munoz, where 70-90% reduction of PM 2.5 was observed since the ECQ. Overall, the study revealed that lockdown measures, fortunately, have brought the opportunity to rationalize human impact on the environment. Although we could say those travel restrictions or lockdown is an unconventional measure to air pollution prevention and control, it is possible to improve air quality by reducing nonessential individual movements by highlighting the importance of fuel-free activities or implementing short-term lockdowns (3-5 days).

Full text

Abstract:

Ethylene response factor 1 (ERF1) is a transcriptional factor from Arabidopsis thaliana that regulates plant resistance to the necrotrophic fungi Botrytis cinerea and Plectosphaerella cucumerina and whose overexpression enhances resistance to these fungi. Here, we show that ERF1 also mediates Arabidopsis resistance to the soilborne fungi Fusarium oxysporum sp. conglutinans and F. oxysporum f. sp. lycopersici, because its constitutive expression in Arabidopsis confers enhanced resistance to these pathogens. Expression of ERF1 was upregulated after inoculation with F. oxysporum f. sp. conglutinans, and this response was blocked in ein2-5 and coi1-1 mutants, impaired in the ethylene (ET) and jasmonic acid (JA) signal pathways, respectively, which further indicates that ERF1 is a downstream component of ET and JA defense responses. The signal transduction network controlling resistance to F. oxysporum fungi was explored using signaling-defective mutants in ET (ein2-5), JA (jar1-1), and salicylic acid (SA) (NahG, sid2-1, eds5-1, npr1-1, pad4-1, eds1-1, and pad2-1) transduction pathways. This analysis revealed that Arabidopsis resistance to F. oxysporum requires the ET, JA, and SA signaling pathways and the NPR1 gene, although it is independent of the PAD4 and EDS1 functions.

Abstract:

Introduction. Pseudomonas aeruginosa grows in extracellular DNA (eDNA)-enriched biofilms and infection sites. eDNA is generally considered to be a structural biofilm polymer required for aggregation and biofilm maturation. In addition, eDNA can sequester divalent metal cations, acidify growth media and serve as a nutrient source. Aim. We wanted to determine the genome-wide influence on the transcriptome of planktonic P. aeruginosa PAO1 grown in the presence of eDNA. Methodology. RNA-seq analysis was performed to determine the genome-wide effects on gene expression of PAO1 grown with eDNA. Transcriptional lux fusions were used to confirm eDNA regulation and to validate phenotypes associated with growth in eDNA. Results. The transcriptome of eDNA-regulated genes included 89 induced and 76 repressed genes (FDR<0.05). A large number of eDNA-induced genes appear to be involved in utilizing DNA as a nutrient. Several eDNA-induced genes are also induced by acidic pH 5.5, and eDNA/acidic pH promoted an acid tolerance response in P. aeruginosa . The cyoABCDE terminal oxidase is induced by both eDNA and pH 5.5, and contributed to the acid tolerance phenotype. Quantitative metal analysis confirmed that DNA binds to diverse metals, which helps explain why many genes involved in a general uptake of metals were controlled by eDNA. Growth in the presence of eDNA also promoted intracellular bacterial survival and influenced virulence in the acute infection model of fruit flies. Conclusion. The diverse functions of the eDNA-regulated genes underscore the important role of this extracellular polymer in promoting antibiotic resistance, virulence, acid tolerance and nutrient utilization; phenotypes that contribute to long-term survival.

Abstract:

Environmental DNA (eDNA) is increasingly used to measure biodiversity of marine ecosystems, yet key aspects of the temporal dynamics of eDNA remain unknown. Of particular interest is in situ persistence of eDNA signals in dynamic marine environments, as eDNA degradation rates have predominantly been quantified through mesocosm studies. To determine in situ eDNA residence times, we introduced an eDNA signal from a non-native fish into a protected bay of a Southern California rocky reef ecosystem, and then measured changes in both introduced and background eDNA signals across a fixed transect over 96 hours. Foreign eDNA signal was no longer detected only 7.5 hours after introduction, a time substantially shorter than the multi-day persistence times in laboratory studies. Moreover, the foreign eDNA signal spread along the entire 38 m transect within 1.5 hours after introduction, indicating that transport and diffusion play a role in eDNA detectability even in protected low energy marine environments. Similarly, native vertebrate eDNA signals varied greatly over the 96 hours of observation as well as within two additional nearby fixed transects sampled over 120 hours. While community structure did significantly change across time of day and tidal direction, neither accounted for the majority of observed variation. Combined, results show that both foreign and native eDNA signatures can exhibit substantial temporal heterogeneity, even on hourly time scales. Further work exploring eDNA decay from lagrangian perspective and quantifying effects of sample and technical replication are needed to better understand temporal variation of eDNA signatures in nearshore marine environments.

Abstract:

Environmental DNA (eDNA) is an increasingly used non-invasive molecular tool for detecting species presence and monitoring populations. In this article, we review the current state of non-avian reptile eDNA work in aquatic systems, and present a field experiment on detecting the presence of painted turtle (Chrysemys picta) eDNA. Thus far, turtle and snake eDNA studies have shown mixed results in detecting the presence of these animals under field conditions. However, some instances of low detection rates and non-detection occur for these non-avian reptiles, especially for squamates. We explored non-avian reptile eDNA quantification by sampling four lentic ponds with different densities (0 kg/ha, 6 kg/ha, 9 kg/ha, and 13 kg/ha) of painted turtles over three months to detect differences in eDNA using a qPCR assay amplifying the COI gene of the mtDNA genome. Only one sample of the highest-density pond amplified eDNA for a positive detection. Yet, estimates of eDNA concentration from pond eDNA were rank-order correlated with turtle density. We present the “shedding hypothesis”—the possibility that animals with hard, keratinized integument do not shed as much DNA as mucus-covered organisms—as a potential challenge for eDNA studies. Despite challenges with eDNA inhibition and availability in water samples, we remain hopeful that eDNA can be used to detect freshwater turtles in the field. We provide key recommendations for biologists wishing to use eDNA methods for detecting non-avian reptiles.

Abstract:

Environmental DNA (eDNA) methods for detecting aquatic species are advancing rapidly, but with little evaluation of field protocols or precision of resulting estimates. We compared sampling results from traditional field methods with eDNA methods for two amphibians in 13 streams in central Idaho, USA. We also evaluated three water collection protocols and the influence of sampling location, time of day, and distance from animals on eDNA concentration in the water. We found no difference in detection or amount of eDNA among water collection protocols. eDNA methods had slightly higher detection rates than traditional field methods, particularly when species occurred at low densities. eDNA concentration was positively related to field-measured density, biomass, and proportion of transects occupied. Precision of eDNA-based abundance estimates increased with the amount of eDNA in the water and the number of replicate subsamples collected. eDNA concentration did not vary significantly with sample location in the stream, time of day, or distance downstream from animals. Our results further advance the implementation of eDNA methods for monitoring aquatic vertebrates in stream habitats.

Abstract:

Environmental DNA (eDNA) analysis with species-specific primer/probe sets is promising as a tool to quantify fish abundance and distribution. Nevertheless, several factors could reduce the accuracy of this method. Here, we aimed to analyze whether intraspecific variability and diel activity rhythm affect eDNA detection in Japanese eels (Anguilla japonica). For this purpose, we performed tank experiments focusing on two points. First, we assessed the effects of base pair sequences with probe region polymorphism on eDNA detection. Next, we evaluated the influences of diel rhythm, activity, and individual differences in eDNA release rate on eDNA concentration. We examined the base pair sequences of the probe regions of 20 individuals and found genetic mismatches in two of them. The eDNA concentration was estimated to be much lower in these variants than it was in the other individuals. We conducted a rearing experiment on four non-variant individuals to explore the influences of diel activity and inter-individual differences in eDNA detection. Nocturnal eel activity was reflected in the eDNA detection but the inter-individual differences remained large. The observed weak positive correlations between eDNA concentration and activity suggest that eDNA emission is highly dependent on basal metabolism. The present study suggests that consideration of polymorphic sites at the probe region and diel activity rhythms should improve the accuracy and precision of abundance estimation through eDNA. Such fine-tuning is applicable not only for eels but also for other fishes to be targeted by eDNA technology.

Abstract:

Environmental DNA (eDNA) is a powerful tool for monitoring the distribution of aquatic macro-organisms. However, environmental factors, including the water temperature and water quality, can affect the inhibition and/or degradation of eDNA, which complicates accurate estimations of eDNA concentrations and the detection of the presence/absence of species in natural habitats. Further very few eDNA studies have been conducted for reptiles, especially with respect to estimating their biomass and/or abundances. Here we examined the relationship between the visually-observed number of red-eared sliders (Trachemys scripta elegans) and eDNA concentrations across 100 ponds. Additionally, we evaluated the effect of water quality on red-eared slider eDNA concentration in these ponds. We found that there was a significant positive correlation between the observed number of red-eared sliders and the eDNA concentration in the ponds. On comparing various water quality indicators, including dissolved nitrogen, dissolved phosphorous, organic matter, and chlorophyll a (Chl. a), we found that only Chl. a had a negative correlation with the red-eared slider eDNA concentration, while we did not find any inhibition in the quantitative PCR. We conclude that concentrations of eDNA can potentially be used for estimating the abundance of the red-eared slider. Additionally, Chl. a might indirectly influence the degradation of eDNA through the microorganisms bonded to the phytoplankton in the ponds, as microbial activity is thought to decrease eDNA persistence.

Abstract:

Environmental DNA (eDNA) sampling has proven to be a valuable tool for detecting species in aquatic ecosystems. Within this rapidly evolving field, a promising application is the ability to obtain quantitative estimates of relative species abundance based on eDNA concentration rather than traditionally labor-intensive methods. We investigated the relationship between eDNA concentration and Arctic char (Salvelinus alpinus) abundance in five well-studied natural lakes; additionally, we examined the effects of different temporal (e.g., season) and spatial (e.g., depth) scales on eDNA concentration. Concentrations of eDNA were linearly correlated with char population estimates ([Formula: see text] = 0.78) and exponentially correlated with char densities ([Formula: see text] = 0.96 by area; 0.82 by volume). Across lakes, eDNA concentrations were greater and more homogeneous in the water column during mixis; however, when stratified, eDNA concentrations were greater in the hypolimnion. Overall, our findings demonstrate that eDNA techniques can produce effective estimates of relative fish abundance in natural lakes. These findings can guide future studies to improve and expand eDNA methods while informing research and management using rapid and minimally invasive sampling.

Abstract:

Detecting environmental DNA (eDNA) in water samples is a powerful tool in determining the presence of rare aquatic species. However, many open questions remain as to how biological and physical conditions in flowing waters influence eDNA. Motivated by what one might find in a stream/river benthos we conducted experiments in continuous flow columns packed with porous substrates to explore eDNA transport and ask whether substrate type and the presence of colonized biofilms plays an important role for eDNA retention. To interpret our data, and for modelling purposes, we began with the assumption that eDNA could be treated as a classical tracer. Comparing our experimental data with traditional transport models, we found that eDNA behaves anomalously, displaying characteristics of a heterogeneous, polydisperse substance with particle-like behaviour that can be filtered by the substrate. Columns were quickly flushed of suspended eDNA particles while a significant amount of particles never made it through and were retained in the column, as calculated from a mass balance. Suspended eDNA was exported through the column, regardless of biofilm colonization. Our results indicate that the variable particle size of eDNA results in stochastic retention, release and transport, which may influence the interpretation eDNA detection in biological systems.

Abstract In this paper, we have simulated an optical 32 channel WDM system with 10 Gbps data rate for various hybrid amplifiers at varying lengths. Stand-alone EDFA gives better performance than other individual amplifiers but when hybrid with Raman amplifier, the performance of the WDM system is enhanced. A lot of researchers are working on the hybrid amplifiers like EDFA and Raman. In this research paper we have also included latest amplifier such as Ytterbium and Praseodymium amplifiers and the performance of the various hybrid combinations is compared. So, different hybrid amplifiers such as Raman-EDFA, EDFA-Yb, Raman-Yb, EDFA-Pr and Raman-Pr have been analyzed for performance parameters like quality factor, bit error rate, eye height and channel power. The analysis shows that EDFA-Pr has maximum Q-factor of 15.4883 at 80 km. EDFA-Pr has a maximum eye opening of 0.00534 at 80 km of length but at 120 km transmission distance EDFA-Yb shows maximum eye opening of 0.00154. Below 100 km of transmission distance, EDFA-Pr shows minimum BER value ranging from 10–54 to 10–20 but as the length is increased above 100 km EDFA-Yb shows better performance with values ranging from 10–16 to 10–09.

Further, the EDFA conversion efficiency (CE) as a function of laser pump powers is presented. Simplified mathematical expressions for the EDFA gain, NF, and CE are provided. The C-band EDFA signal gain remained flat in the spectral region 1539 to 1562 nm. Moreover, the C-band EDFA NF increased with wavelength and decreased with the 1480 nm laser pump powers.

Abstract:

Environmental DNA (eDNA) techniques are gaining attention as cost-effective, non-invasive strategies for acquiring information on fish and other aquatic organisms from water samples. Currently, eDNA approaches are used to detect specific fish species and determine fish community diversity. Various protocols used with eDNA methods for aquatic organism detection have been reported in different eDNA studies, but there are no general recommendations for fish detection. Herein, we reviewed 168 papers to supplement and highlight the key criteria for each step of eDNA technology in fish detection and provide general suggestions for eliminating detection errors. Although there is no unified recommendation for the application of diverse eDNA in detecting fish species, in most cases, 1 or 2 L surface water collection and eDNA capture on 0.7-μm glass fiber filters followed by extraction with a DNeasy Blood and Tissue Kit or PowerWater DNA Isolation Kit are useful for obtaining high-quality eDNA. Subsequently, species-specific quantitative polymerase chain reaction (qPCR) assays based on mitochondrial cytochrome b gene markers or eDNA metabarcoding based on both 12S and 16S rRNA markers via high-throughput sequencing can effectively detect target DNA or estimate species richness. Furthermore, detection errors can be minimized by mitigating contamination, negative control, PCR replication, and using multiple genetic markers. Our aim is to provide a useful strategy for fish eDNA technology that can be applied by researchers, advisors, and managers.
