Improvements on the Pfafstetter basin coding system proposal
Authors: Teixeira Alexandre de Amorim , Silva Adalene Moreira , Pruski Fernando Falco , Davis Jr Clodoveu , Roig Henrique Llacer , Diniz Noris Costa
Published: April 2022

ABSTRACT The coding basin system proposed by Pfafstetter (1989) is an important reference point and adopted by the principal water resources management system in the world. This adoption is due to the method’s simplicity and the topological relationship between the river stretches built-into the codes. Otherwise, the Pfafstetter basin coding system can only be applied in a hydrographic vector represented by an anti-arborescence binary graph. This type of representation causes loss of hydrographic information due to the simplification of regions where there are anabranching, braided or delta areas that implies multiple confluences, cycles or disruptions of the network. This paper proposes improvements to the Pfafstetter basin coding system, maintaining it simple, while keeping the topological relationship between the stretches and including the possibility to represent the hydrography with multiple confluences, cycles, delta mouths, sinks, water masses and disruptions to drainage.
Morphological and molecular characterization of Austrodiplostomum compactum metacercariae in the eyes and brains of fishes from the Ivaí River, Brazil

Published: April 2022

Abstract Austrodiplostomum spp. (Platyhelminthes: Digenea) are endoparasites with a broad geographic distribution in South America. During the larval stage, they parasitize the eyes, brains, muscles, gill, kidneys and swim bladder of a wide variety of fishes. The metacercariae of Austrodiplostomum spp. have several morphological characteristics during development, but are very similar among species, which makes it necessary to use molecular tools to contribute to the elucidation during the larval stage. The objective of this study was to perform morphological and molecular analyses of Austrodiplostomum sp. found in specimens of Hypostomus sourced from the Ivaí River in the state of Paraná, Brazil. Of the 93 analyzed specimens (H. hermanni [n = 50], H. albopunctatus [n = 9], Hypostomus sp. 1 [n = 24], and Hypostomus sp. 2 [n = 10]), 60 were parasitized. A total of 577 Austrodiplostomum sp. metacercariae was collected from the infected hosts; DNA from seven of these samples was extracted, amplified, and sequenced. The morphological data associated with the genetic distance values and the relationships observed in the COI gene tree, indicate that all metacercariae were A. compactum. This is the first record of A. compactum parasitizing H. hermanni, H. albopunctatus, Hypostomus sp. 1, and Hypostomus sp. 2 in the Ivaí River.
Cardiovascular manifestation of end-stage liver disease and perioperative echocardiography for liver transplantation: anesthesiologist’s view
Authors: Han Sangbin , Park Jaesik , Hong Sang Hyun , Park Chul Soo , Choi Jongho , Chae Min Suk
Published: April 2022

Liver transplantation (LT) is the curative therapy for decompensated cirrhosis. However, anesthesiologists can find it challenging to manage patients undergoing LT due to the underlying pathologic conditions of patients with end-stage liver disease and the high invasiveness of the procedure, which is frequently accompanied by massive blood loss. Echocardiography is a non-invasive or semi-invasive imaging tool that provides real-time information about the structural and functional status of the heart and is considered to be able to improve outcomes by enabling accurate and detailed assessments. This article reviews the pathophysiologic changes of the heart accompanied by cirrhosis that mainly affect hemodynamics. We also present a comparative review of the diagnostic criteria for cirrhotic cardiomyopathy published by the World Congress of Gastroenterology in 2005 and the Cirrhotic Cardiomyopathy Consortium in 2019. This article discusses the conditions that could affect hemodynamic stability and postoperative outcomes, such as coronary artery disease, left ventricular outflow tract obstruction, portopulmonary hypertension, hepatopulmonary syndrome, pericardial effusion, cardiac tamponade, patent foramen ovale, and ascites. Finally, we cover a number of intraoperative factors that should be considered, including intraoperative blood loss, rapid reaccumulation of ascites, manipulation of the inferior vena cava, post-reperfusion syndrome, and adverse effects of excessive fluid infusion and transfusion. This article aimed to summarize the cardiovascular manifestations of cirrhosis that can affect hemodynamics and can be evaluated using perioperative echocardiography. We hope that this article will provide information about the hemodynamic characteristics of LT recipients and stimulate more active use of perioperative echocardiography.
Choice of neuromuscular block reversal agent to reduce postoperative pulmonary complications
Authors: Cho Sung-Ae , Sung Tae-Yun
Published: April 2022

The definition of postoperative pulmonary complications (PPCs) is inconsistent in literature; however, PPCs include pulmonary abnormalities that adversely affect patient outcomes, such as respiratory failure, atelectasis, pneumonia, pleural effusion, and exacerbation of underlying lung conditions. Furthermore, although the incidence of PPCs varies according to its definition, surgery type, and patient population, they can lead to increased morbidity, mortality, duration of hospitalization, and medical costs; thus, efforts to identify and reduce the risk factors are important to improve patient outcomes. Among the risk factors for PPCs, residual neuromuscular block is a representative and preventable anesthesia-related risk factor that is affected by the choice of the reversal agent. However, it is not clear whether the chosen reversal agent, i.e., sugammadex, reduces PPCs better when compared to anticholinesterases. Additionally, the effects of the reversal agents on PPCs in high-risk patients, such as elderly patients, pediatric patients, those with end-stage renal disease, obesity, obstructive sleep apnea, or those undergoing specific surgeries, are diverse. To reduce the PPCs associated with the use of neuromuscular blocking agents, it is important to confirm complete reversal of the neuromuscular block under neuromuscular monitoring. Additionally, efforts to reduce the incidence of PPCs through interdisciplinary communication are required.

How the Teaching Development Grant was used (and the problem of common-sense understandings of teaching and learning)
Authors: Moyo Temwa , McKenna Sioux , Ndebele Clever
Published: April 2022

Teachers at primary and secondary education levels are required to hold a professional qualification but, at the higher education level, all that is required is content expertise. This may well contribute to South Africa's low university throughput and retention rates, in response to which, since 2004, the state has provided ZAR5.5 billion in the form of the Teaching Development Grant (now the University Capacity Development Grant) to address poor completion rates. We present an analysis of the use of the grant across the sector using a social realist framework. Every academic and student has themselves been taught and so have developed untheorised assumptions about curriculum and pedagogy. Such common-sense assumptions about teaching and learning often serve to reinforce the status quo, which is particularly problematic in a sector with poor and racially differentiated throughput and success rates. Many initiatives funded through the grant evidenced a reliance on common-sense assumptions rather than on theorised accounts. In particular, student development often took the form of remedial, add-on initiatives that left the mainstream curriculum untouched-and staff development was often generic and short term. We also found that expertise in academic development, which could potentially challenge common-sense assumptions, was unevenly distributed.

Published: April 2022

Las prácticas de exclusión son experiencias sociales lesivas para la identidad y la autopercepción de quienes las padecen. Entre los diversos grupos sociales que históricamente han vivido prácticas de exclusión social están las minorías sexuales. Este artículo explora las experiencias de exclusión social de cinco personas transgénero, en tres universidades de la ciudad de Medellín (Colombia). El método utilizado fue el hermenéutico y la técnica de recolección de la información fue la entrevista episódica. Los resultados evidenciaron que hay una ausencia de políticas inclusivas hacia las personas transgénero en las universidades, que implican vulnerabilidad, invisibilización y marginalidad, teniendo efectos en su autopercepción e inserción social.

Authors: Sánchez Gómez Rosalba , Cárdenas Rodríguez Edna Katherine
Published: April 2022

El objetivo de esta investigación fue conocer las representaciones sociales de la mujer en estudiantes de quinto grado de una institución educativa pública de Tunja. Es un estudio cualitativo interpretativo. Se utilizaron las técnicas red de asociaciones, grupos focales y observación, a partir de lo cual emergieron cuatro categorías sobre la mujer: ser de otro, imagen pública, contestaria y ser sexual. Se logra constatar que la representación de la mujer se configura, principalmente, a partir de las características biológicas, que, como lo plantea Colín (2013), determinan su ser en el mundo; también se evidencia una construcción identitaria con base en los parámetros socioculturalmente normalizados, propiciando el mantenimiento de relaciones de poder entre los sexos (Lagarde, 2005), el sometimiento, la discriminación hacia lo femenino y el rechazo hacia otras formas de ser mujer.

Authors: Castellanos Paola , Londoño Constanza
Published: April 2022

El objetivo del presente estudio cualitativo tenía como objetivo comprender la relación entre la identificación como fumador (identidad de consumo) y la percepción del riesgo en adolescentes universitarios adolescentes fumadores. Para recolectar la información se realizaron entrevistas a profundidad de forma individual a 10 adolescentes entre 17 y 20 años de edad. Se analizaron los resultados usando el programa Atlas T. Los resultados evidencian que existe relación entre el nivel de consumo y el grado de identificación con el consumo de cigarrillo. Las tasas más bajas de consumo e identificación, se relacionaron con menor percepción del riesgo e intentos de cesación y menor probabilidad percibida de adoptar cambios. Adicionalmente respecto de la identidad de consumo se observa que las valoraciones, atribuciones y expectativas representan factores importantes para el inicio y mantenimiento del hábito de fumar y se relaciona con los niveles de consumo en la población universitaria.

Authors: Ali Paiwand , Qader Ari , Hasan Hawree , Rasul Faraydoon , Hiwa Vyan
Published: April 2022

Background 
Upper lid blepharoplasty is one of the most commonly performed procedures in aesthetic plastic surgery, which directly affects facial rejuvenation. The periocular region is the main point of focus in routine face-to-face interaction. Understanding the periorbital surgical anatomy, facial analysis, and specific change in the skin, muscle and fat with preoperative workup and a thoughtfully conceived surgical plan targeted according to the difference gives a successful outcome.
Objectives 
This dynamic region has both functional and aesthetic influence on the face; unfortunately, this area develops ageing sooner than other regions of the face.
Patients and Methods
A total of 30 patients underwent upper lid blepharoplasty. In the most lateral part, the orbicularis oculi muscle was divided horizontally. The lower part was suspended to the periosteum of the orbital rim with a single stitch of the long-standing absorbable suture. The upper part overlapped over the lower part of the muscle and fixed them by a single stitch in a single stitch pant over vest fashion.
Results
This technique provides more youthfulness to the eye, especially at the region of lateral canthus, as it lifts the tissue superolateral. It has minimal effect on lateral canthus laxity but shows marked improvement in lateral lower lid and crowfeet; it also shows valuable improvement of lateral hooding. 
Conclusion
The orbicularis oculi muscle suspension procedure is a good technique that reliably corrects and reshapes the outer portion of both upper and lower eyelids. It is an easy technique, and it would be helpful as an adjunctive procedure with blepharoplasty in selected cases.
DYSAUTONOMIA FOLLOWING ACUTE ISCHEMIC STROKES: A SINGLE INSTITUTIONAL EXPERIENCE
Authors: Shekhbzeni Aso
Published: April 2022

Background 

Many studies have found that patients with ischemic stroke can develop autonomic system disturbances, affecting the heart, causing different types of arrhythmias and even sudden death. 

Objectives 

To analyze the occurrence of cardiovascular autonomic dysfunction and cardiac arrhythmias after acute ischemic stroke.

Patients and Methods

This case-controlled study was conducted at the Rizgary Teaching Hospital from July 1st, 2018, to September 30th, 2019. Fifty patients with acute ischemic stroke were enrolled consecutively and were age-matched and gender-matched with a group of 50 individuals (control group). Four bedside autonomic function tests (deep breathing, heart rate response to standing, isometric handgrip test, and blood pressure response to standing) were used to assess autonomic dysfunction during the acute post-stroke phase. In addition, all patients and controls underwent 24-hour Holter cardiac monitoring.

Results

Although abnormal autonomic function testing was more frequent in post-stroke cases than in healthy controls, there was no statistically significant difference in these results among stroke sub-groups. There were more arrhythmias in patients with stroke in comparison with the control group; premature ventricular and atrial contractions were more frequent in stroke patients than in the control group (P-value <0.001 and P-value<0.001, respectively). 

Conclusion

Cardiac dysautonomia is common in patients with acute ischemic stroke, and cardiac dysrhythmias are commonly encountered in patients with insular infarctions. Whether these dysrhythmias are life-threatening or not, further analytic studies are required to uncover their clinical significance.

Authors: Rahman Renas , Fattah Chro
Published: April 2022

Background  Interpregnancy interval is a modifiable risk factor for adverse outcomes in infants and their mothers. The World Health Organization proposed that women wait a minimum of twenty-four months following a live birth and six months following a miscarriage before conceiving again. Objectives  The aim is to assess the outcome of pregnancy and complications correlated with an interpregnancy interval following a prior pregnancy loss. Patients and Methods This is a prospective comparative study that includes 100 patients in a maternity teaching hospital in Sulaymaniyah - Iraq, between April 2020 to March 2021, divided into two groups of 50 patients each, as groups A and B. One group has an interpregnancy interval <3 months and the other group has interpregnancy interval ≥ 3 months. This study included women whose final reproductive outcomes were a pregnancy loss and afterwards became pregnant. The study outcome included the outcome of the pregnancy, whether delivered by caesarian section or vaginal delivery, the outcome of the baby including birth weight and APGAR score in 1 minute and 10 minutes, and whether admitted to the Neonatal Care Unit or not. The outcome also included the pregnancy complications such as pregnancy loss, type of the pregnancy loss, and complications of the pregnancy (pre-eclampsia, gestational diabetes, and preterm birth <37weeks). Results The pregnancy outcomes turned out as 76 cases of live births, and 24 cases of miscarriage. From live births, 58 cases were delivered vaginally, and 18 cases were delivered by caesarean section.  Conclusion This study showed that conception within 12 weeks of prior miscarriage, was not related to an increased liability of poor pregnancy outcomes.
Design and Analysis of Soft Computing Based Improved Routing Protocol in WSN for Energy Efficiency and Lifetime Enhancement
Authors: Paliwal Rakesh , Khan Irfan
Published: April 2022

Mobile wireless sensor networks have been developed as a result of recent advancements in wireless technologies. Sensors in the network are low-cost and have a short battery life, in addition to their mobility. They are more applicable in terms of the essential properties of these networks. These networks have a variety of uses, including search and rescue operations, health and environmental monitoring, and intelligent traffic management systems, among others. According to the application requirements, mobile wireless sensor nodes are energy limited equipment, so energy conservation is one of the most significant considerations in the design of these networks. Aside from the issues posed by sensor node mobility, we should also consider routing and dynamic clustering. According to studies, cluster models with configurable parameters have a substantial impact on reducing energy usage and extending the network's lifetime. As a result, the primary goal of this study is to describe and select a smart method for clustering in mobile wireless sensor networks utilizing evolutionary algorithms in order to extend the network's lifetime and ensure packet delivery accuracy. For grouping sensor nodes in this work, the Genetic Algorithm is applied initially, followed by Bacterial Conjugation. The simulation's results show a significant increase in clustering speed acceleration. The speed of the nodes is taken into account in the suggested approach for calibrating mobile wireless sensor nodes.

Mucormycosis is a life-threatening, locally invasive, rapidly progressive, opportunistic fungal infection, associated with several anaesthetic challenges.

We aimed to study its relation with patient’s comorbidities, covid treatment strategies, also to observe the intubation difficulties, changes in hemodynamic parameters, post anaesthesia recovery status and perioperative complications.

In this time bound study, total 160 patients were included. During pre-anaesthetic evaluation, presence of associated co-morbidities, course of Covid-19 disease, requirement of O2 therapy were noted. On the day of surgery, premedications and sedation were given. Induction was done with propofol/etomidate along with sevoflurane/desflurane. Intubation was done with succinyl choline/ atracurium and difficulties in intubation were graded according to Modified Intubation Difficulty Scale. Anaesthesia was maintained with the mixture of Oxygen, Air and inhalation agent along with intermittent Atracurium. Hemodynamic parameters, intra operative and post operative outcome were noted. Unstable patients were shifted to intensive care unit.

Among patients of rhino-orbito-cerebral mucormycosis, most common co morbidity found was diabetes mellitus (42%). Here, 61% were on room air, rest needed oxygen therapy. Total 52% patients required >/= 2 intubation attempts, in which 9% were video laryngoscope assisted and 11% required additional maneuvers. 22% patients were started on intravenous nitroglycerin to manage intraoperative hypertension. 9.3% patients required ICU admission, of which 2.5% could not survive.

Possibilities of developing rhino-orbito-cerebral mucormycosis in patients having diabetes mellitus are high. The anaesthetic management requires eternal vigilance to encounter difficult intubation, delayed recovery, and higher rate of morbidity and mortality.

Authors: Peng Yufei , Li Hua , Li Xiaoyan , Wang Jikang , Zhang Xinyu
Published: April 2022

In the optical storage DC microgrid in island mode, in view of the large inrush current problem of the inverter controlled by the optical storage VSG when switching from off-grid to grid-connected operation mode, a pre-synchronization control strategy based on secondary frequency regulation and voltage regulation was proposed. This strategy can adjust the large frequency and voltage fluctuations caused by active and reactive load changes under the independent DC microgrid of the optical storage. At the same time, it can complete the effective tracking of the grid phase before connecting to the grid, and reduce the impulse current when the optical storage microgrid is isolated and connected to the grid. The real-time digital simulation platform (RTDS) is used to simulate and analyze the proposed control scheme, and the simulation results verify the feasibility of the proposed control strategy.

De esta manera, se impulsó la cultura y aprendizaje mediante una red de centros culturales y parques biblioteca; así como mejorando la movilidad urbana. Debido a que el contexto de Lima se asemeja tanto social como geográficamente a Medellín, la hipótesis consiste en diseñar un Parque Biblioteca en el distrito de Independencia, Lima, Perú con el fin de brindar a una determinada comunidad espacios que fomentarían el aprendizaje continuo, las actividades culturales, el ocio, el entretenimiento, la recreación y el deporte. De este modo, esta biblioteca estaría actualizada a las tecnologías contemporáneas y adaptadas al contexto local al incluir espacios interiores de interés de la comunidad; así como una extensa área verde y espacios exteriores en respuesta al deporte que practican en la zona. Adicionalmente, esta biblioteca cuenta con un centro cultural que contiene espacios para eventos públicos o privados, talleres polivalentes, áreas de estudio y espacios de reunión para la comunidad. Se aplica el énfasis basado en la teoría de Learning Streets del Arq. Prakash Nair, la cual consiste en utilizar circulaciones y espacios residuales para fomentar el aprendizaje continuo. Por último, en el parque se incluyen actividades que carecía el terreno original, como juegos infantiles, plataformas de baile, lugares de reunión, área deportiva y sendas peatonales.

Authors:   Institute of Physics and Mathematics FRC Komi SC UB RAS, Gromov N.A.
Published: April 2022

The behavior of amplitudes and cross section of the main processes, caused by electromagnetic and weak interactions of particles during the contraction of the Standard Model gauge group is analysed. The dependences of the elastic scattering cross sections of photons, electrons (positrons) and neutrinos (antineutrinos) on electrons, as well as the annihilation of electrons and positrons into two photons, into a neutrino-antineutrino pair, into a muon-antimuonpair on the temperature of the Universe are established, taking into account that the contraction parameteris inversely proportional to the temperature ε∼T−1.
Solving the inverse electrical problem in materials science: generalized Voight model
Authors:   Institute of Chemistry FRC Komi SC UB RAS, Sekushin N.A.
Published: April 2022

This work deals with the theoretical foundations of high-frequency impedance spectroscopy used for the study of functional polycrystalline materials. A method for constructing an electrical model of a sample in the form of a classical and generalized Voight scheme is described. The impedance hodograph of the classical Voight scheme is an overlay ofsemi-circles, from which geometric dimensions it is possible to determine the parameters of the equivalent scheme. It is shown that for inhomogeneous materials, the considered semicircles are rotated relative to the origin of the complex plane and shifted horizontally. To model such systems, it is necessary to use a generalized Voight scheme, in which thecapacitors are replaced with elements of a constant phase. The ways of transition from the “inconvenient” parameters of such two-poles to the electrical characteristics of the material volume are considered. Three new integral characteristics of an inhomogeneous medium are proposed: the peak parameters on the imaginary impedance frequency characteristic (the frequency of the impedance resonance and the half-width of the peak). Both values canbe determined without measuring the geometric dimensions of the sample. In addition, the “dielectricloss correction factor” has been introduced, which affects the horizontal offset of the impedance frequency response.

Published: April 2022

Microblogging is a new and socialized media form born of the fourth industrial revolution. In every sense, aggressive development has far-reaching effects on humanity. Stakeholders, non-profit groups, and state and non-state actors are all interested in internet marketing. A vast number of social websites, such as Twitter, Tumblr, Plurk, and others, have recently gained popularity among normal internet users. This study sought to illustrate how microblogging has driven the market to expand and established tactics in such a period. The study used an exploratory research approach with a focus on literature in the fields of business administration, entrepreneurship, internet academic journal, blogs, government publications and records, a variety of research reports, and individual research. The study established that users relied on microblogging to share different types of information through frequent and lengthy conversions and microblogging marketing is an aggressive alternative source of business growth. Therefore, Microblogging marketing has contributed to global business and supported marketing strategy. The study suggested that microblogging marketing should be users’ friendly, actively forward users' objective quality evaluation products, and create a harmonious and equitable social media environment. Further research should be conducted to determine how corporate microblogging might benefit workers at work and business world

La  COVID-19 y la continuidad de la emergencia sanitaria han generado  que durante el 2021 se mantenga el distanciamiento social y los cuidados en el aforo de los espacios públicos. Esto ha   ocasionado que la presencialidad a clases aún se vea afectada,  obligando a que las instituciones de educación superior continúen via remota sus actividades. La carrera de odontología es eminentemente práctica, en ese sentido muchos de los cursos tuvieron que experimentar una adecuación a esta nueva contingencia. En el presente artículo se presentan las adecuaciones, estrategias y metodologías aplicadas en dos cursos de carrera eminentemente clínicos que se imparten en el sexto y séptimo ciclo de la carrera de odontológia de la Facultad de Estomatología de la Universidad Peruana Cayetano Heredia, denominados Clínica Integral del Adulto III y Clínica Integral del Adulto IV que se imparten en el primer y segundo semestre de cada año. Se muestra cómo se llevaron a cabo estos cursos vía remota  y usando un modelo de simulación personalizado (Maqueta-UPCH)  con el objetivo de llevar a cabo la adquisición de competencias por parte de los alumnos. Esta es una experiencia inédita  nunca antes descrita a la fecha.
A narrative review of graduate employability models: their paradigms, and relationships to teaching and curricula
Authors: Cook Elizabeth J.
Published: April 2022

Increasingly governments expect universities to improve graduate employment outcomes. Universities respond by implementing employability strategies in, alongside and outside curricula, with debates ongoing about whether employability is part of the curriculum, why and how. The context and process of employability is commonly framed in neoliberal and human capital paradigms. Some academics are resistant to their university’s employability strategy and programmes often adopt a ‘bolt on’ approach, which is outside the curriculum. At this time, the world is in the midst of multiple crises, linked to sustainability, technology and survival in societies, which are redefining and affecting life and work. With all these tensions in mind, should universities reconsider how they think and act with respect to graduate employability, careers and the world of work? What are the key values of employability paradigms and models, and how do they connect to the curriculum? This paper presents a narrative review of conceptual employability models published in the peer reviewed higher education literature since 2000 with each model positioned on a continuum based on its: (1) paradigm, i.e., underlying beliefs about careers, employability and employment; and (2) relationship to teaching and curricula (i.e., intra-, extra- and/or co-). I observe that most models are focused on the employability of individuals (i.e., career, skills, capabilities) and economic success (i.e., markets, knowledge economy, workforce), with limited consideration of wider contributions to local and global career development through social, ecological or technological lenses. Models with stronger individualistic focus appear to be less connected to teaching and curricula than models that also focus on others. The potential implications of these observations for universities and teaching and learning are discussed.
Ecological impacts of the African sharptooth catfish Clarias gariepinus in the Guapi-Macacu, a River in the Guapimirim Environmental Protection Area, southeastern Brazil
Authors: Dumith Michelle Torres , Santos Alejandra FGN
Published: April 2022

The African sharptooth catfish (Clarias gariepinus) is the most important catfish species for aquaculture. It has great capacity to endure several stressing factors, such as adverse environmental conditions, as well as a broad feeding flexibility. Notwithstanding, the presence of this alien fish in the Guapimirim Environmental Preservation Area, in Southeast of Brazil, may generate negative impacts on the community of native fish. In 2018, during dry and rainy seasons, samples from the fish community were collected in thirty-two sites of the Guapi-Macacu River, and the abiotic variables (salinity, pH, temperature, turbidity, dissolved oxygen, and transparency) were assessed to diagnose which factors influence in the distribution of the alien fish along the river. Moreover, species within the ichthyofauna were evaluated as bioindicators to identify possible alterations in the community. Multivariate analyzes indicated that the African sharptooth catfish dominates the buffer zone of the environmental protection area, benefiting from higher levels of dissolved oxygen and temperature. However, C. gariepinus still do not dominate the most protected area of Guapimirim, where a higher percentage of native fish species dwell. The alterations in abiotic factors, related to the increase in the temperature, may significantly contribute to the domination of this invading alien fish in this protected area, being necessary the constant monitoring of some key species, as well as the population of the invading species in this environmental preservation area.
