“…Collection of relatively rare freshwater fauna depends on factors such as the number of samples collected, the size of the waterbodies studied (Azovsky, 2011; Vieira et al., 2017), and the complexity and effectiveness of the sampling methods and approaches used (Castilho et al., 2016; Gutkowska et al, 2013). We tried to increase and balance sampling effort in each studied region by adding species lists from respective regional literature (including other waterbodies and periods).…”

1. Broad-scale assessment of biodiversity is needed for detection of future changes across substantial regions of the Arctic. Presently, there are large data and information gaps in species composition and richness of the freshwater planktonic and meiobenthos communities of the Russian Arctic. Analysis of these data is very important for identifying the spatial distribution and temporal changes in species richness and diversity of rotifers, cladocerans, and copepods in the continental Russian Arctic.2. We investigated biogeographic patterns of freshwater plankton and meiobenthos from c. 67° to 73°N by analysing data over the period 1960-2017. These data include information on the composition of rotifers, cladocerans, and copepods obtained from planktonic and meiobenthic samples, as well as from subfossil remains in bottom sediments of seven regions from the Kola Peninsula in the west, to the Indigirka River Basin (east Siberia) in the east. 3. Total richness included 175 species comprised of 49 rotifer genera, 81 species from 40 cladoceran genera, and 101 species from 42 genera of calanoid, cyclopoid, and harpacticoid copepods. Longitudinal trends in rotifer and micro-crustacean diversity were revealed by change in species composition from Europe to eastern Siberia. The most common and widespread species were 19 ubiquitous taxa that included Kellicottia longispina (Rotifera), Chydorus sphaericus s. lat. (Cladocera), Heterocope borealis, Acanthocyclops vernalis, and Moraria duthiei (Copepoda). The highest number of rare species was recorded in the well-studied region of the Bolshezemelskaya tundra and in the Putorana Plateau.4. The total number of copepod and rotifer species in both Arctic lakes and ponds tended to increase with latitude. Relative species richness of copepods was positively associated with waterbody area, elevation, and precipitation, while relative species richness of cladocerans was positively related to temperature. This result is consistent with known thermophilic characteristics of cladocerans and the cold tolerance properties of copepods, with the former being dominant in shallow, warmer waterbodies of some western regions, and the latter being dominant in This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…This was calculated with the following formula: C = p.100/P, where C is the constancy index, p is the number of samples where the species occurred, and P is the total number of samples. Also, species were classified as constant (present in > 80% of samples), frequent (50-80%), common (20-50%) and rare (< 20%) (Castilho et al, 2016).…”

Adjacent environments contribute to the increase of zooplankton species in a neotropical river

Aim:The distribution of the zooplankton community along the Paraná River and in adjacent environments (tributaries and lakes) was evaluated, as well as the contribution of the community present in these environments to the species composition of the Paraná River. It was expected that the ensemble of species found in the last sampling site of the Paraná River would represent the accumulation of species found in the upstream sites. Methods: The community was sampled at 25 sites, during 2013 and 2014, and the species richness and composition were determined. The similarity in the composition of the community between the environments was evaluated using cluster analysis, and the contribution of the species to the Paraná River was evaluated using nestedness analysis, using the NODF index. Results: Overall, 193 species were registered (116 rotifers, 48 cladocerans and 29 copepods), with the majority of species considered as rare (163 species). In general, the composition of the community in the river was dissimilar to the adjacent environments, although there was a relationship among communities. Rotifers presented broad distribution throughout the area. As expected, the zooplanktonic species presented a nested distribution, with the last river site representing a set of the species registered in the upstream sites. Conclusion: The results show the importance of the tributaries and lakes to the occurrence of species along the river. The distinct hydrological characteristics of the environments, as well as flow velocity, depth and connectivity, were responsible for the development of planktonic populations in the lakes that arrived in the main river through tributaries. With these results, we suggest the importance of the conservation of adjacent environments of the Paraná River for the maintenance of the zooplanktonic species in this system.

“…A riqueza foi representada pelo número de espécies e a densidade numérica expressa em organismos por metro cúbico (org./m³). A classificação da frequência de ocorrência foi baseada em Dajoz (1983) e Castilho et al (2016): espécies constantes ocorrem em mais de 50% das amostras, de 25% a 50% são consideradas espécies acessórias e percentuais menores que 25% espécies acidentais.…”

RESUMO: As comunidades zooplanctônicas são importantes componentes na cadeia alimentar considerando os produtores primários e os demais níveis. Além disso, algumas espécies são sensíveis ou tolerantes à poluição orgânica. Aqui testamos a hipótese de que a composição de espécies varia conforme o gradiente de eutrofização. Buscou-se estabelecer os possíveis fatores ambientais responsáveis pela variação na distribuição das espécies. Esse estudo teve como objetivo caracterizar a comunidade zooplanctônica e relacionar os dados com a qualidade da água em reservatórios do Estado de São Paulo. Amostras foram coletadas através de arrasto vertical por meio de rede de plâncton (68 (m) em sete corpos d’água. Todos os espécimes foram identificados através de literatura específica e contados em camâra de Sedgwick rafter. Os dados bióticos e abióticos foram analisados através da análise de correspondência canônica. Um total de 67 táxons foram encontrados, sendo Rotifera o predominante. No geral, os reservatórios apresentaram condições eutróficas, principalmente Salto Grande, Barra Bonita e Broa. Os resultados apontaram que os rotíferos Trichocerca longiseta (Schrank, 1802), Hexarthra sp., Brachiounus spp. e Keratella tropica (Apstein, 1907) seguiram o gradiente de eutrofização. Além desses, microcrustáceos como Notodiaptomus, Mesocyclops, Metacyclops e Diaphanossoma ocorreram em reservatórios eutróficos. Por outro lado, os cládoceros Ceriodaphnia cornuta (Sars, 1886) e Bosminopsis deitersi Richard, 1895 foram considerados indicadores de melhor qualidade devido à relação com águas mais transparentes. Os resultados apontam que algumas espécies do zooplâncton são efetivas para o monitoramento ambiental sem descartar as análises físico-químicas e biológicas.
