Full textAbstract:
AbstractIn 2003, the parasite fauna of 197 European eelsAnguilla anguilla, captured at three different locations (Laufenburg, Karlsruhe and Beneeden Leeuwen) in the River Rhine, was analysed. The eels harboured a total of 18 species, among them the protozoa (Myxidium giardi, Myxobolus kotlaniandTrypanosoma granulosum), acanthocephalans (Acanthocephalus anguillae, Acanthocephalus lucii, Echinorhynchus truttae, Pomphorhynchus laevis), nematodes (Paraquimperia tenerrima, Pseudocapillaria tomentosa, Camallanus lacustris, Raphidascaris acus, Spinitectus inermisandAnguillicola crassus), cestodes (Bothriocephalus clavicepsandProteocephalus macrocephalus) and monogeneans (Pseudodactylogyrussp.). The parasite fauna at the different locations is discussed with respect to the crustacean fauna present at these locations. The investigation shows that changes in the composition of the crustacean fauna, due to the anthropogenic breakdown of a biogeographic barrier, are reflected in the composition of the intestinal eel parasite fauna.

This study aims to study the pike (Esox lucius) parasitic fauna in the Vyatka River of the Kirov region. Studies were conducted at two sites in the middle of the river Vyatka in 2016–2018 The distance between them is 300 km. A total of 26 individuals were investigated. Caught specimens of fish were examined for the presence of parasites in accordance with generally accepted methods. Over the entire period of studying the pike parasite fauna in the Vyatka River, 24 different parasite species were recorded by various researchers. As a result of our research, 9 species of parasites were recorded, trematodes – 1 species – Azygia lucii, cestodes – 1 species - Triaenophorus nodulosus, nematodes – 2 species – Сamallanus lacustris, Raphidascaris acus, proboscis worm – 3 species – Acanthocephalus anguillae, Acanthocephalus lucii, Neoechinorhynchus rutili, crustaceans 1 species – Ergasilus sieboldi and glochidia 1 species – Anodonta cygnea. The total infection of pike with all kinds of parasites was 100%, with intestinal species – 66.6%. The high extensiveness of invasion is marked by crustaceans Ergasilus sieboldi – 73.1%. The study provides a comparative analysis of the parasite fauna of the common pike in the Vyatka River over 80 years. There is a tendency to reduce the species diversity of pike parasites from 24 species to 9, the disappearance of some species and the acquisition of new ones – proboscis worm Acanthocephalus anguillae with extensiveness of invasion – 15.4%, intensity of invasion – 5.3 specimen, abundance index – 0.81 specimen. The results obtained allow us to conclude that there is a significant decrease in the species diversity of pike parasites, which is probably due to the influence of the anthropogenic factor.

Apresenta-se uma reflexão crítica sobre os caminhos da técnica com destaque para a sua relação com uma economia capitalista que vê na natureza apenas uma fonte de lucro. Analisam-se as relações entre a teoria da sociedade do risco, a formação dos refugiados ambientais e as históricas violências estruturais que demarcam o Brasil Contemporâneo. Por outro lado, a realidade da fauna brasileira e o cenário de violação causado pelo ser humano como uma força geológica prejudicial à preservação dos animais não humanos, têm sido fator que contribui para o agravamento da situação ambiental. Discutem-se as contradições do contrato político quando se trata da proteção dos animais não humanos.

Full textAbstract:
The composition of the helminth fauna of the main commercial fish species in the lake ecosystem of the Narochansky National Park was determined. It is represented by 10 species of helminths having a complex development cycle with the participation of intermediate hosts, as well as 1 species of helminths (Gyrodactylus sp.), a representative of cl. Monogenea, having a direct development cycle. It was noted that the highest level of invasion was typical for larvae of trematodes Tylodelphys conifera. The greatest variety of parasitic helminths is observed in fish from lake Miastro and Naroch (7 species of helminths each). It was revealed that the most common representatives of the helminth fauna of fish inhabiting the lakes of Narochansky National Park are metacercariae of trematodes of the Diplostomum genus. They were found in fish in all water reservoirs examined. Their host spectrum was also the widest. Examination of the three-spine stickleback showed a severe damage by plerocercoids Ligula intestinalis (prevalence 92% to 98.4%, infection intensity 1–4 pairs per fish). In addition, proboscis worms Acanthocephalus lucii were found in the intestines of the three-spine stickleback. The trematode fauna of fish muscles from the Naroch lake group is rather poor and represented by three types of helminths: Rhipidocotyle illense, Paracoenogonimus ovatus and Apophallus muelingi.

Full textAbstract:
One of the predators of the ichthyofauna of the Lower Tobol is Esox lucius (Linnaeus, 1758) (Esociformes, Esocidae). The purpose of this work is to study the current state of the E. lucius parasite fauna in the lower reaches of the Tobol River. In the present study 47 individuals of the northern pike of different sex aged from 2+ to 8+ years were examined by the method of complete parasitological dissection. As a result of the research, 23 types of parasites were found in the pike. The largest number of species of parasitic organisms – 20 – were found in May, 12 were found in December and 11 in September. Of these, 10 species are specific to northern pike: Haemogregarina esoci (Nawrotzky, 1914), Chloromyxum esocinum (Dogiel, 1934), Myxidium lieberkuhni (Biitschli, 1882), Myxosoma anurum (Cohn, 1895), Henneguya psorospermica (Thelohan, 1995), Tetraonchus monenteron (Wagener, 1857), Gyrodactylus lucii (Kulakowskaja, 1951), Triaenophorus nodulosus (Pallas, 1781), Azygia lucii (Miiller, 1776), Raphidascaris acus (Bloch, 1779). For the first time an intraerythrocyte parasite – H. esoci – was found in pike in the Lower Tobol, the extensiveness of invasion was 18.7% in December, and 6.2% in May. Epistylis sp. and Trichodinella epizzotica parasitized on the surface of the body of fish only in May, whereas members of the genus Trichodina were found in winter and spring. In all seasons, parasitization by M. anurum and H. psorospermica was established on the gills. The greatest occurrence of spores of M. lieberkuhni and C. esocinum was observed in the spring. Myxosporidia parasitized in the kidneys and T. monenteron parasitized on the gills during all periods of the study (the latter with an extensivity of invasion of 100.0%). All examined fish are infected with T. nodulosus 100.0% of cases. In May, other types of cestodes were found: P. esocis and Dibothriocephalus latus. Three pike were infected with proteocephalis. The larval stage of diphyllobothriid was found in one fish in the liver and gonads in an amount of 139 individuals. In the pikes’ stomach, during all periods of the study, A. lucii was found in all the fish examined. In the autumn period of the study immature R. campanula were found in in the intestine of 4 fish specimens. The nematode R. acus was found in pike only in spring. This nematode was found in fish aged 4+–8+. In May, glochidia with a high intensity of invasion were found on fins, gill covers and gills of fish. E. sieboldi copepods were found on the gills; in May, one specimen was found in one pike and in September in 6 with AI of 0.7. Tetraonchus monenteron was a dominant species, in May its degree of dominance decreased with the greatest uniformity of species in this study period. Having considered the age dynamics of pike infection by various types of parasites, it was found that in the age group 4+–5+ the number of species of parasites was greatest (20), while in groups 2+–3+ and 6+–8+ it was 14. In the pike, the core parasitic fauna were M. anurum, H. psorospermica, T. monenteron, T. nodulosus, A. lucii. Seasonality has virtually no effect on the degree of infection with specific parasites. The age of fish largely determines the qualitative and quantitative composition of the parasite fauna.

Full textAbstract:
Frutos e sementes (diásporos) possuem adaptações às diversas formas de dispersão e a grande variedade nessas estruturas torna complexa sua classificação morfológica e identificação do material botânico quando coletado em fruto. O uso das chaves convencionais muitas vezes trava o processo devido à terminologia pouco usual, e a aplicação de chaves interativas pode ser uma alternativa. Pesquisas no Cerrado sobre dispersão mostraram que as espécies zoocóricas são maioria, principalmente em fitofisionomias florestais. Devido à diversidade morfológica, caracteres estruturais dos diásporos podem ser comparados para identificação das plantas, principalmente quando associados a um banco de imagens com exemplos ilustrados que torne o processo acessível. O objetivo desse trabalho foi a construção de uma chave interativa ilustrada para identificação de espécies do Cerrado do Jardim Botânico de Brasília que são dispersas pela fauna. Foram obtidas 157 espécies zoocóricas com frutos frescos e maduros, distribuídas em 61 famílias e 111 gêneros. A chave eletrônica foi confeccionada no “Lucid”, programa de chaves interativas de múltipla entrada que possibilita uso de imagens. A chave foi testada com alunos de graduação da Universidade de Brasília e tem se mostrado uma ferramenta prática na identificação das espécies, já estando disponível gratuitamente no site www.frutosatrativosdocerrado.bio.br.

Full textAbstract:
The present study presents the results from examinations of bleak’s endohelminth species and structure of helminth communities from the Bulgarian part of the Lower Danube River. In 2015 and 2016, on a seasonal manner, 91 specimens of Alburnus alburnus (Linnaeus, 1758) (bleak) were examined with standard techniques for parasites. Five species of parasites: Nicolla skrjabini (Ivanitzky, 1928), Ligula intestinalis (Linnaeus, 1758), Acanthocephalus lucii (Müller, 1776), Pomphorhynchus laevis (Müller, 1776) and Contracoecum microcephalum (Stossich, 1890), larvae were identified. The analysis of the dominant structure of the found parasite species is presented to the component and infracommunities levels. All parasite species were accidental for the parasitic communities of examined fish with the exception of P. laevis and N. skrjabini. P. laevis was a core parasite species and N. skrjabini was a component parasite species for the helminth communities of bleak. The parasite communities of A. alburnus were discussed and compared with previous research data on parasite communities of bleak from River Danube in Bulgaria. New data for helminths and helminth communities of A. alburnus from Danube River (biotope Vetren) and their seasonal occurrence are presented.

En Nicaragua los estudios de la Malacofauna del Occidente son relativamente pocos, principalmente para la clase Gasterópoda, teniendo como únicas referencias dentro del país estudios realizados por MARENA, COMAP, USAID y FUNCOD en el 2002, en el cual identificaron cerca de 106 especies entre flora y fauna , en el cual se mencionan algunos bivalvos, por otro lado Santana Aguilar en el 2006, identifico 70 especies de bivalvos y 92 gasterópodos en la Reserva Natural Cosigüina, por ultimo pero no menos importante los libros recopilados por López y Urcuyo en el 2008, quienes realizan un registro de las principales características de ambas clases, dividiendo la información en dos tomos, uno para cada uno, dando un registro fotográfico al final de cada toma de las especies de bivalvos y gasterópodos más comunes en el Pacifico. Sin embargo, estos estudios no toman un registro concreto de la parte costera de León, el cual presenta una diversidad de especies de ambas clases y que son de gran interés comercial para los comunitarios, puesto que es su fuente de ingresos económicos, por ello, surge la iniciativa de realizar este estudio en la Isla Santa Lucia, la cual es considerada una zona de amortiguamiento de la Reserva Natural Juan Venado, compartiendo especies tanto de flora y fauna. El estudio se realizó en los meses de septiembre a noviembre, luego de finalizar el período de veda de la clase Bivalvia, teniendo muestreos cada 20 días, tomando como referencia la línea costera noroeste de la Isla Santa Lucia, las caletas de “El Rosario” y “El Gancho” (las cuales se caracterizan por presentar la mayor estación de bivalvos y algunos gasterópodos, según indicaban lugareños), se capturaban un total de 360 especímenes, de los cuales se identificaron la presencia de 19 especies en tallas de 1 centímetro a 22.9 centímetros, predominando en el caso de los bivalvos el género Anadara sp., de la clase de los gasterópodos las especies de Rhinocoryne homboltdti, seguido de Cerithidae sp., e Ilichione subrugosa, presentando la zona costera mayor diversidad de especies de la clase gasterópoda en comparación a las caletas, no obstante las caletas presentaron mayor dominancia de especies de la clase Bivalvia.

Realizou-se estudo da fauna de fitonematóides em dois municípios do estado de São Paulo (Pariquera-Açu e Cananéia) sob domínio da Mata Atlântica e dois do estado do Mato Grosso (Nova Maringá e Guarantã do Norte) sob domínio da Floresta Amazônica, com o objetivo de conhecer a diversidade de fitonematóides desses biomas e avaliar o efeito do uso agrícola do solo sobre a comunidade de fitonematóides. Para tanto, foram efetuadas amostragens em áreas de vegetação primária e em áreas próximas cultivadas. Para cada amostra, foram extraídos os nematóides de 200 cm³ de solo e em 10 gramas de raízes pela técnica de peneiramento combinada com flutuação em centrífuga com solução de sacarose. Em seguida, os espécimes foram mortos pelo calor e fixados em formalina. Os nematóides foram posteriormente quantificados, para determinação da abundância de cada táxon, sendo as identificações taxonômicas realizadas com base em características morfológicas e morfométricas. Os dados foram analisados com base na abundância, freqüência e índices de similaridade (Jaccard e Bray e Curtis). Assinalaram-se 34 gêneros e as identificações específicas foram efetuadas para 22 táxons. Para a espécie Aorolaimus banoae foram apresentadas novas características morfológicas e morfométricas. Observou-se que, com a retirada da vegetação primária e a implantação dos cultivos de plantas perenes ou anuais, houve intenso processo de redução da diversidade de fitonematóides e da introdução de novos táxons, o que resultou em baixa similaridade entre os locais de vegetação primária e aqueles cultivados, demostrando-se elevada influência da atividade agrícola sobre a comunidade de fitonematóides.A study about plant parasitic nematode fauna was conducted in two municipalities from São Paulo State (Pariquera-Açu and Cananéia in the Atlantic Forest) and two from Mato Grosso State (Nova Maringá and Guarantã do Norte in the Amazon Forest), Brazil. The aims of this study were to evaluate the diversity of plant-parasitic nematode fauna in locations of primary and to evaluate the effect of agricultural land use on the plant parasitic nematode communities. Nematodes were extracted from 200 cm³ of soil and 10 grams of roots by a sieving and sugar flotations technique and fixed with formalin. Nematodes were counted for determination of abundances of each taxon and the taxonomic identification was based on morphological and morphometric features. The following variables were obtained: abundance, frequency and similarity indexes (Jaccard and Bray e Curtis). A total number of 34 genera were recorded and 22 taxons were identified at species level. Concerning Aorolaimus banoae species, new morphological and morphometric features were presented. It was observed that, after removal of primary vegetation and implantation of perennial or annual crops, occurred a conspicuous reduction of plant parasitic nematode diversity, associated with introduction of exotic species, resulting in low similarity between location of primary vegetation and the cultivated ones. The results demonstrated that the agricultural practices affect strongly the plant parasitic nematode communities.

Full textAbstract:
Nos últimos anos houve um crescimento exponencial da energia solar fotovoltaica no Brasil, incentivado pelo interesse do setor financeiro rentista no desenvolvimento de grandes projetos de energias renováveis. O pensamento assentado na racionalidade colonial é observado na expansão energética brasileira, com a priorização do lucro e na acumulação de capital, em detrimento do meio ambiente. A busca por investimentos criou uma competição entre Estados e a flexibilização das exigências ambientais transformou o licenciamento ambiental em uma mera formalidade, dada a facilidade de obtenção. Verificou-se ainda a inexistência de políticas públicas no país para o aproveitamento de áreas degradadas ou em processo de desertificação para a geração de energia limpa. Por fim, percebe-se que o bioma semiárido é o mais afetado com a transição energética brasileira, já que concentra grande parte dos novos projetos, com grandes impactos ambientais para a sua fauna e flora.
