Redescription of Bryconamericus iheringii (Boulenger, 1887) (Characiformes: Characidae).
No full textBryconamericus iheringii (Boulenger, 1887) was described from the laguna dos Patos basin, where it is widely distributed. Together with other species that occur exclusively in the south of Neotropical region, B. iheringii forms a clade characterized by the subterminal mouth, always at level of ventral margin of the orbit; 5–6 rows of scales above lateral line; teeth of the outer row of premaxilla aligned; and dentary with teeth gradually decreasing in an anteroposterior direction. The lack of taxonomic studies regarding B. iheringii makes it difficult to identify it in relation to other congeners, as well as to determine its area of occurrence. The objective of this work was to restrict Bryconamericus iheringii to populations that are phenotypically closer to the lectotype of the species. For this, 225 specimens from the laguna dos Patos and rio Uruguai basins were analyzed. Of these, 131 specimens were identified as B. iheringii and supported the redescription proposed here. Furthermore, we present a new diagnostic proposal for B. ikaa and B. ytu. Bryconamericus iheringii is diagnosed from B. ikaa by color and B. ytu by the number of gill-rakers. Bryconamericus pliodus and B. boops are maintained as junior synonyms of B. iheringii. Finally, we suggest carrying out analyzes in populations distributed in other basins (upper and lower Paraná basins) to determine whether or not these populations belong to B.Bryconamericus iheringii (Boulenger, 1887) foi descrita da bacia da laguna dos Patos, onde é amplamente distribuída. Junto de outras espécies que ocorrem exclusivamente no Sul da região Neotropical, B. iheringii forma um clado caracterizado pela boca subterminal, sempre ao nível da margem ventral da órbita; 5-6 séries de escamas acima da linha lateral; dentes da série externa do pré-maxilar alinhados; e dentário com dentes decrescendo gradativamente em sentido anteroposterior. A falta de estudos taxonômicos aprofundados em relação a B. iheringii torna difícil a sua identificação em relação as demais congêneres, bem como a determinação de sua área de ocorrência. O propósito deste trabalho foi restringir Bryconamericus iheringii às populações que mais se aproximam, fenotipicamente, do lectótipo da espécie. Para isso, foram analisados 225 exemplares provenientes das bacias da laguna dos Patos e do rio Uruguai. Destes, 131 exemplares foram identificados como B. iheringii e embasaram a redescrição aqui proposta. Apresenta-se uma nova proposta de diagnose para B. ikaa e B. ytu. Bryconamericus iheringii é diagnosticada de B. ikaa pela coloração, e de B. ytu pelo número de rastros branquiais. Bryconamericus pliodus e B. boops são mantidos como sinônimos-júniores de B. iheringii. Ao final, recomendamos a realização de análises em populações distribuídas em outras bacias (alto e baixo Paraná) para determinar se estas populações pertencem ou não a B. iheringii.Master
Закономерности формирования волновой активности в прибрежном районе юго-восточной части российского сектора Черного моря
No full textThe wave regime of the coastal waters in the Southeastern Russian sector of the Black Sea has been described based on the data of the wave-measuring station located in the area adjacent to Tuapse. The data of observations for the time range from 1975 to 2005 were used. Such characteristics as wave types, fetch lengths, wave type repeatability by month and direction, wave repeatability for the waves of different heights, the number of days with storm wave action, and the duration of storm wave conditions have been investigated. It is shown that the sea wave action in the coastal waters near Tuapse is determined by the observed wind, the influence of open sea waves, as well as by the orography of the sea port area, open to the wave systems from the southwest, south, and, to a lesser extent, from the west.Описан режим волнения в прибрежной части юго-восточного района российского сектора Черного моря по данным волномерного поста, расположенного в районе г. Туапсе. Использованы данные наблюдений за период 1975–2005 гг. Изучены такие характеристики, как типы волнения, длина разгона волн, повторяемость типов волнения моря по месяцам и по направлениям, повторяемость волн различной высоты, число дней со штормовым волнением, продолжительность штормовых волнений. Показано, что волнение моря в прибрежном районе Туапсе определяется наблюдаемым ветром, влиянием волнения открытого моря, а также орографией акватории порта, доступной для систем морских волн от юго-запада, юга, в меньшей степени — от запада.PublishedNon Referee

First record de miniaturization in Parodontidae (Actynopteri: Characiformes), with the description de four new species in the Upper Rio Paraná e Rio São Francisco basins.
No full textThe fish de the genus Apareiodon belonging to the family Parodontidae comprises 14 valid species. They are rheophilic species, usually living in places with running water e rocky bottom. The three genera can be differentiated by the absence e presence de anatomical characters. Miniature fishes are those that have reduced standard length in the adult stage, compared to non-miniature species, relative to non-miniature species, and are often accompanied by pedomorphism. Miniaturization can be separated into two groups: those with identical shape to non-miniature species but reduced size, e those with reduced size with juvenile characteristics. In this paper, the first four miniature species de the genus are described. The new species are: Apareiodon sp. n. 1 known from a marginal pond of the Rio Verde, upper Paraná river basin; Apareiodon sp. n. 2 known from the Rio Mourão, upper Paraná river basin; Apareiodon sp. n. 3 known from Lagoa 45 and Lagoa do Parente from the Rio Turvo, upper Paraná river basin e Apareiodon sp. n. 4 known from a marginal pond of the Rio Boa Vista, São Francisco river basin. The species differ from their congeners by their reduced size, a black spot on the caudal peduncle, more rays on the pectoral fin e fewer cusps on the teeth. The lack of research and data on miniaturization in this genus regarding taxonomic, ecological e natural history aspects is highlighted,and this work is the first record containing data and information on the group. The miniaturization, taxonomic aspects e geographical distribution de the new species are discussed.Os peixes do gênero Apareiodon pertencente à família Parodontidae compreende 14 espécies válidas. São espécies reofílicas, normalmente vivendo em locais de água corrente e fundo rochoso. Os três gêneros podem ser diferenciados pela ausência e presença de caracteres anatômicos. Peixes miniaturas são aqueles que possuem comprimento padrão reduzido na fase adulta, em relação as espécies não miniaturas, e muitas vezes são acompanhados de pedomorfismo. A miniaturização pode ser separada em dois grupos: que possuem forma idêntica às espécies não miniaturas, porém tamanho reduzido, e que possuem tamanho reduzido com características juvenis. São descritas neste trabalho, as quatro primeiras espécies miniaturas do gênero. As novas espécies são: Apareiodon sp. n. 1 conhecida de uma lagoa marginal do rio Verde, bacia do alto rio Paraná; Apareiodon sp. n. 2 conhecida no rio Mourão, bacia do alto rio Paraná; Apareiodon sp. n. 3 conhecida da lagoa 45 e lagoa do Parente do rio Turvo, bacia do alto rio Paraná e Apareiodon sp. n. 4 conhecida de uma lagoa marginal do rio Boa Vista, bacia do rio São Francisco. As espécies se diferenciam das congêneres por possuírem tamanho reduzido, uma mancha preta no pedúnculo caudal, mais raios na nadadeira peitoral e menos cúspides nos dentes. Destaca-se a falta de pesquisas e dados em relação á miniaturização neste gênero quanto aos aspectos taxonômicos, ecológicos e história natural, sendo este trabalho o primeiro registro contendo dados e informações sobre o grupo. São discutidos a miniaturização, aspectos taxonômicos e distribuição geográfica das novas espécies.Master
To use, or not to use plastic- that is the question: Well, I would say REUSE
No full textPlastic, a material often regarded as one of the biggest threats to the environment, has become so ingrained in our lives that we find it almost everywhere, ranging from something as small as a toothbrush to massive containers. In fact, this subject has gained so much prevalence that no science lectures in schools are complete without discussing the detrimental effects of plastic, which have become so deeply embedded in our brains that the moment I hear plastic, I see an ambulance siren wailing, screaming at the top of its lungs, “PLASTIC IS BAD, STAY AWAY”.Challenge 10: Change humanity’s relationship with the ocean.Publishe

A review of aquatic toxicology investigations in Turkish waters.
No full textAquatic toxicity studies have been conducted for many years, and their importance has been understood for some time. The need for aquatic toxicity studies arises from the widespread use of chemicals in many different industries, such as agriculture, manufacturing, and energy production. These chemicals can enter aquatic environments through various means, including runoff from fields, discharges from factories, and spills or leaks from storage tanks or pipelines. Once in the aquatic environment, these chemicals can have harmful effects on aquatic life, including fish, crustaceans, molluscs, and algae. By conducting aquatic toxicity studies, researchers can gain a better understanding of the potential harmful effects of chemicals on aquatic life and ecosystems and can inform decisions about their use and regulation to protect the environment. This review summarizes the available aquatic toxicity studies in Turkish waters.PublishedReferee

Considerations on the low-altitude operations of the cruising-type AUV Gondou for seafloor photographic surveys.
No full textThe Japan Coast Guard AUV Gondou is a cruising-type autonomous underwater vehicle. The Gondou is equipped with a downward-looking camera system that potentially unveils detailed seafloor feature from a different perspective than acoustic observations. As the Gondou is designed to run at relatively high-speed for wide-range seafloor mapping, the vehicle has limited maneuverability in horizontal and vertical directions. These operational characteristics of the vehicle require careful considerations in the design of mission planning and predetermination of contingency avoiding behaviors. This technical report notes our operational efforts to conduct seafloor photographic surveys with the cruising-type AUV.PublishedReferee
