Abstract: Southern river otter densities of 0.03 to 0.62/km of river were estimated for three rivers of the coast of the Mexican State of Oaxaca by the number of feces found on transects. The estimated population for the 19 perennial rivers of the state was 495. Scat analysis showed that crustaceans, fish, insects and amphibians are the main components of the otter’s diet.  Keywords: Lontra longicaudis, density, abundance, diet, Ayuta, Copalita, Zimatán. Palabras clave: Lontra longicaudis, densidad, abundancia, alimentación, Ayuta, Copalita, Zimatán.

AbstractDue to human activities, some species have expanded their distribution into areas that were historically difficult or impossible to reach by natural dispersal. Such species may become invasive if they successfully establish reproductive populations. Predation is one of the main barriers that exotic species may face in newly colonized areas. We evaluated the effect of an invasive prey (armored catfish:Pterygoplichtyssp.) on the dietary niche breadth and trophic level of a native predator (Neotropical river otter:Lontra longicaudis) in northern Guatemala. We examined otter scats from three rivers: two where the invasive armored catfish occurred and one without the invasive fish. Samples were collected two and seven years after the first report of the catfish in the area. We performed gross scat analysis and stable isotope analyses of nitrogen and carbon of fecal matter. Where the invasive armored catfish occurred, it was the main prey item forL. longicaudis. Particularly in the river outside of protected areas seven years after the first report of the catfish, where it accounted for 49% of the otter diet. Concordance was found between the two techniques to estimate dietary niche breadth and trophic level. The dietary niche breath of otters was narrower seven years after the invasion in comparison to two years after the invasion in both invaded rivers, but, the extent of the reduction was less inside the protected area. Finally, the trophic level of otters also showed a reduction related to the occurrence of the armored catfish on their diet.ResumenComo producto de las actividades humanas algunas especies han expandido su distribución hacia áreas que históricamente eran difícil o imposible de alcanzar mediante de dispersión natural. Estas especies pueden convertirse en invasoras si establecen exitosamente poblaciones reproductivas. La depredación es una de las principales barreras que las especies exóticas deben afrontar en las áreas recientemente colonizadas. Evaluamos los efectos de una especie invasora (el pez diablo:Pterygoplichtyssp.) sobre la amplitud de nicho alimenticio y el nivel trófico de un depredador nativo (la nutria de rio Neo-tropical:Lontra longicaudis) en el norte de Guatemala. Examinamos las excretas de nutrias provenientes de tres ríos: dos donde el pez diablo se encuentra presente y uno donde este invasor aún está ausente. Las muestras fueron colectadas dos y siete años después del primer reporte de del pez diablo en le área. Realizamos un análisis macroscópico de las excretas y análisis de isotopos estables de nitrógeno y carbono de la materia fecal. Donde el pez diablo invasor estaba presente, fue el principal ítem alimenticio deL. longicaudis. Particularmente en el río ubicado fuera de áreas protegidas siete años después del primer reporte del pez diablo, donde este consistió en el 49% de la dieta de la nutria. Encontramos concordancia entre las dos técnicas para estimar la amplitud de nicho dietario y nivel trófico. La amplitud de nicho dietario de las nutrias fue más angosto siete años después de la invasión en comparación con dos años luego de la invasión en ambos ríos invadidos, pero la magnitud de la reducción fue inferior dentro del área protegida. Finalmente, observamos una reducción en el nivel trófico de las nutrias relacionada con la ocurrencia del pez diablo en su dieta.

A utilização de novas metodologias em sala de aula é um assunto recorrente dentro das discussões sobre o ensino de geografia. Possuindo isso em mente, como produto da disciplina de Oficina em Geografia II da Universidade Estadual do Ceará (UECE) foi elaborado um material didático alternativo com objetivo de auxiliar os docentes na construção de um ensino contextualizado de Geografia. Essa pesquisa objetiva apresentar uma metodologia alternativa para o ensino de Geografia que visa praticar além da ação cognitiva de memorizar um conceito, trabalhando a interdisciplinaridade, a criatividade, o emocional e a cooperação. A proposta foi construir um RPG (Role Playing Game), que é um jogo que se utiliza da interpretação de personagens para criar e contar histórias coletivamente nas quais todos os agentes se tornam ativos dentro desse processo. Realizaram-se os seguintes procedimentos: revisão bibliográfica, seleção e adaptação do sistema de regras. Por fim, produziu-se a aventura de RPG intitulada “A busca pelo arco de Gelo”, que trabalha alguns aspectos físicos do nordeste brasileiro principalmente do estado do Ceará. Após a elaboração do material constatou-se a importância de trabalhar perspectivas para além do conteudismo. Sentiu-se a necessidade de aplicar no ensino básico para mensurar seu real impacto. Palavras-chave:  Recurso Didático. RPG. Geografia Física. ABSTRACTThe use of innovative methodologies in the classroom is a recurring subject in discussions about geography teaching. With that in mind, as a result of the discipline Workshop in Geography II from the State University of Ceará (UECE) was created, an alternative didactic material with the aid of teachers in the construction of a contextualized geography teaching. This research looks to show an alternative perspective for the teaching of geography that aims to practice beyond the cognitive action of memorizing the concept, but also working on interdisciplinary, creativity, the emotional and cooperation. The proposal was to build an RPG (Role Playing Game), which is a game that uses character interpretation to create and tell stories collectively in which all agents become active within that process. The following procedures were executed: bibliographic review, selection and adaptation of the rules system. At the end, it produced an adventure of RPG "The search for the arc of Ice" that works on physical aspects from the Brazilian northeast, focusing on the state of Ceará. After the material elaboration, it was clear the importance to work on perspectives beyond content. It felt the need to apply the didactic resource to measure its real impact.

The Impact

Income tax in many countries is one of the main sources of filling the public budget and levers of influence on the development of economic processes at the macro level. The income tax ensures the balance of economic interests of the state, legal entities and individuals and the avoidance of excessive tax pressure. The impact of European integration processes on the Ukrainian accounting system increases the relevance of the development of the organization and methods of accounting for income tax. The purpose of the article is to establish the main phases of the evolution of the concept of “income tax”, clarify its economic content and identify the characteristics as an object of accounting. The article examines the historical phases of the income tax evolution, taking into account amendments in the tax law in Ukraine. A review of interpretations of the concept of “income tax” by foreign and domestic scholars was made, to establish the three main approaches to its interpretation: as a direct tax paid by a business entity from the received profit; as an item of the company financial statement, informing concerned parties on the amount of the assessed and paid tax; as a company’s payment to the state for utilization of economic infrastructure and resources. The author’s definition of the concept of “income tax” is proposed, which contributes to the clarification of the accounting terminology. It is argued that income tax should be considered through the prism of the tax law and accounting standards. A comparison of treatment to income tax as an accounting object in the National Accounting Standard 17 “Tax Income” and International Accounting Standards 12 “Income Taxes” is made. Based on a study of the legal framework for the accounting of income tax, its main components are identified as an object of accounting.

The Current Account

The article highlights the features of the formation and assessment of the balance of payments in Ukraine. The balance of payments of Ukraine is a functional macroeconomic model that reflects all transactions that are carried out between the subjects of the national economy and the subjects of the economies of other countries of the world. This model allows you to develop and implement a sound foreign economic policy of Ukraine, analyze the state of commodity and financial markets, conduct scientific research of economic processes in the state, etc. Ukraine is actively implementing the methodology of balance of payments formation according to the recommendations of the International Monetary Fund. Ukraine's balance of payments by main components is grouped into two accounts: "capital and financial transactions" and "current transactions": capital transactions cover all transactions related to the receipt or payment of capital transfers and the acquisition or sale of property rights and non-financial assets; current transactions include all transactions between residents and non-residents on real values, as well as transactions on the free provision or receipt of valuables for current use. Like any other "balance of payments" consists of receipts and payments. It is active (surplus) when revenues are greater than payments and passive (deficit) when payments are greater than revenues. Based on the assessment of the balance of payments of Ukraine for 2020, certain conclusions can be drawn: stable external demand for food softened the drop in exports of goods from Ukraine during the COVID-19 pandemic, and the increase in prices contributed to its growth at the end of 2020; despite a slight recovery in domestic demand in the IV quarters of 2020, imports of goods to Ukraine by the results of 2020 decreased significantly; the current account surplus in Ukraine in 2020 was provided by a significant positive balance of trade in services and a record surplus of the primary income account; capital outflow from Ukraine on the financial account stopped at the end of 2020 due to the optimism of investors; despite the crisis and significant payments on external debt, Ukraine's gross reserves increased in 2020, and the financial crisis once again confirmed the importance of both international support and a balanced macroeconomic policy. The current account surplus in Ukraine in 2020 reached one of the largest levels in the history of Ukraine, it was formed due to a significant decrease in imports of goods and services, a reduction in payments on primary income and the relative stability of exports of goods and remittances. The article proposes recommendations for improving approaches to the formation of the balance of payments in Ukraine using certain methods when regulating the balance of payments of the state.
