A presença de vegetação num ecossistema aquático é mais uma aréa disponível para a colonização. Vários estudos têm demonstrado uma relação positiva entre a presença de macrófitas e a abundância e a diversidade de Chironomidae. As variáveis ambientais e as larvas de Chironomidae associadas com as macrófitas Salvinia sp. e Myriophyllum sp. foram estudadas num reservatório com pequenas dimensões no estado de São Paulo, Brasil. Em Salvinia os grupos predominantes foram Tanytarsus, Monopelopia e Labrundinia, entretanto Cricotopus e Tanytarsus alternaram a dominância em Myriophyllum. Alem disso, discutiu-se a estrutura dos grupos funcionais de alimentação associados a essas macrófitas.

Plant meals from Eichhornia crassipes and Salvinia molesta can be used as alternative ingredients for feed in aquaculture. The purpose of this study was to determine the effect of the use of plant meals as a feed on the growth of Pangasius. The experimental designed consist of three treatments and triplicates: P0: commercial feed (control); P1: feed with the addition of 25% Eichhornia crassipes; P2: feed with the addition of 25% Salvinia molesta. The results showed that plant meals in feed showed significantly different results on the growth of body weight, specific growth rate, and efficiency of Pangasius feed. The recommended treatment was the addition of Salvinia molesta with a weight growth value of 3.84 g, a specific growth rate of 2.07%, and feed efficiency of 59.96%.

This study used two biosorbents obtained from the aquatic plants Salvinia sp. and Pistia stratiotes to establish a sustainable and alternative treatment for industrial wastewater and other water bodies that contain Pb(II). The biosorbent named Salvinia with NaOH (SOH) was obtained from Salvinia sp., and Salvinia and Pistia mixture with NaOH (SPOH) was obtained from a mixture of the two plants in a 1:1 ratio. The biosorbents were characterized by zeta potential, infrared (IR) spectroscopy, scanning electron microscopy (SEM), energy-dispersive spectroscopy and Boehm titration. The results of Boehm titration and IR analysis indicated the presence of basic functional groups, whereas those of SEM analysis indicated that the biosorbents have a structure conducive to adsorption. Batch adsorption experiments were performed to observe the effects of pH, contact time, initial lead concentration and temperature on the metal removal process. The results revealed that the biosorbents efficiently removed Pb(II) from aqueous solutions, with a maximum observed adsorption capacity (saturation limits, qmax) of 202 mg g−1 and 210.1 mg g−1 for SPOH and SOH, respectively. The Freundlich, Langmuir and Dubinin–Radushkevich models were applied to the data; these biosorbent studies did not satisfactorily adjust to either of the models, but the information obtained helped us understand the adsorption mechanism.

As macrófitas possuem complexidades estruturais morfológicas diferentes, oferecendo aos animais a disponibilidade de vários nichos. Esses vegetais também são um importante substrato para o desenvolvimento de perifíton, que possui grande valor nutricional e constitui um dos principais alimentos dos invertebrados aquáticos, principalmente naidídeos. Este estudo teve como objetivo verificar a diversidade da comunidade de Oligochaeta em macrófitas dos gêneros Egeria sp. e Salvinia sp., em lagoas marginais da represa do Ribeirão das Anhumas. Essas macrófitas possuem características tridimensionais distintas e hábitos diferentes, sendo a Egeria submersa fixa e a Salvinia flutuante livre. As coletas das macrófitas foram realizadas entre os meses de agosto de 2012 e abril de 2013. Das amostras vegetais foram tomadas 100 gramas de biomassa (peso úmido) de cada gênero e a remoção das plantas do ambiente foi feita com o auxílio de uma peneira com malha 0,21 mm. Entre as duas macrófitas analisadas, a Egeria sp. foi a que obteve maior diversidade, riqueza e abundância em relação à Salvinia sp. Esses resultados demonstram que as macrófitas aquáticas são importantes para o estabelecimento dos oligoquetos, fornecendo principalmente proteção e alimento, e que possivelmente a morfologia e hábito das plantas são os fatores que mais influenciam na associação da oligogauna com esses vegetais.

The aquatic macrophytes Salvinia sp. and Pistia stratiotes have a natural capacity to adsorb various elements, including heavy metals. This capacity was enhanced with a chemical treatment using NaOH alkaline solution for Salvinia sp. and a mixture of both Salvinia sp. and Pistia stratiotes at a proportion of 1:1, whose respective biosorbents were called SSOH and MBOH. Adsorption tests were done in a ternary system containing the metals copper, lead and manganese; the parameters considered were: starting concentration, kinetics, pH and temperature. The adsorption isotherms for SSOH had a maximum adsorptive capacity of 50.20, 53.85 and 14.68 mg g−1 for Cu, Pb and Mn, respectively; for MBOH, maximum values were 44.62, 35.17 and 15.74 mg g−1 for Cu, Pb and Mn, respectively. The metals displayed different behaviors with pH variation. The results also showed an adsorption preference of Cu > Pb > Mn for SSOH. Desorption and readsorption studies were also carried out, showing 100% desorption and increased adsorption capacity in readsorption tests. Surface area and porosity analysis with the Brunauer–Emmett–Teller (BET) method indicate that after chemical modification, MBOH and SSOH biomasses had their surface increased in comparison to SS, with values of 165.5657 (MBOH), 157.4392 (SSOH) and 78.9432 m2 g−1 (SS).

Full textAbstract:
Existence of heavy metals in industrial waste is gaining global attention since their negative impact to environment. One of the efforts to solve the problem was to use plant to absorb metal in liquid medium, known as rhizofiltration. This research was aimed to select aquatic plants which showed relative resistantce and susceptibility to chromium. Four species of aquatic plants (Pistia stratiotes, Eichhornia crassipes, Lemna minor and Salvinia sp.) were grown in artificial medium (Hoagland) supplemented with 0, 1, 2, 4 and 8 ppm chromium. The plants resistance and absorption toward chromium was observed based on the morphology and chromium content in their biomass. Based on their resistance to and absorption of chromium, the selected plants were tested further in liquid waste of tanning industry. In Hoagland medium, Salvinia sp. demonstrated 67.2% higher resistance and absorption toward chromium while that of P. stratiotes 20.3% lower compared to other plants which were tested. This result could be applicable in reducing such environmental pollutant as the heavy metal chromium from industrial waste.

The aim of this work was to determine the caloric density of leaves, stems and roots of aquatic macrophytes in different environments of the Baía subsystem (Baía river and Fechada and Guaraná lagoons) on the Upper Paraná river floodplain, in addition to identify the variability between ecological groups. Samplings of Eichhornia crassipes, Salvinia spp, Pistia stratiotes, Eichhornia azurea, Polygonum sp, Cyperaceae and Poaceae were carried out in February 2003. Spatial differences in the caloric densities were not observed for these plants. Caloric density values varied from 1906.9 cal/g dry weight (root) to 4675.0 cal/g dry weight (leaf). However, significant differences between the caloric content averages of the vegetative structures were observed only for Polygonum sp and Salvinia spp. In relation to the ecological groups, the highest average value was verified for the emergent macrophytes (3529.7 ± 722.5), which were significantly different from the floating ones (3056.5 ± 571.0). There was no difference between the sites included in the subsystem when the caloric densities were compared.

Assays were carried out to evaluate the consumption of dissolved oxygen resulting from mineralisation processes in resources usually found in aquatic systems. They were also aimed at estimating the oxygen uptake rate of each investigated process. Experiments were conducted using substrates from 3 different places. A fixed amount of substrate was added to 5 litres of water from Lagoa do Infernão that was previously filtered with glass wool. After adding the substrates the bottles were aired and the amount of dissolved oxygen and the temperature were monitored for 55 days. The occurrence of anaerobic processes was avoided by reoxygenating the bottles. The experimental results were fitted to a first order kinetics model, from which the consumption of dissolved oxygen owing to mineralisation processes was obtained. The amount of oxygen uptake from the mineralisation processes appeared in the following decreasing order: Wolffia sp., Cabomba sp., Lemna sp., DOM (Dissolved Organic Matter), Salvinia sp., Scirpus cubensis, stem, Eichhornia azurea, sediment and humic compounds. The deoxygenation rates (day-1) were: 0.267 (humic compounds), 0.230 (Lemna sp.), 0.199 (E. azurea), 0.166 (S. cubensis), 0.132 (sediment), 0.126 (DOM), 0.093 (Cabomba sp.), 0.091 (stem), 0.079 (Salvinia sp. and Wolffia sp.). From these results, 2 groups of resources could be identified: the first one consists of detritus with higher amounts of labile (ready to use) compounds, which show a higher global oxygen uptake during the mineralisation process; the second one consists mainly of resources that show refracting characteristics. However, when the consumption rates are analysed it is noted that the mineralised parts of the refracting substrates can be easier to process than the labile fractions of the less refracting resources.

Abstract. The genus Salvinia is composed of fast-growing floating ferns, capable of surviving in different environmental conditions. Some authors suggest that the relationships between this genus and macroinvertebrates may serve as water quality indicators. The present study aimed to determine the influence of seasonality and water quality on macroinvertebrate diversity associated with the Salvinia biloba Raddi. Water and fern were collected in rainy and dry seasons and was conducted a microbiological analysis of the water, as well as, the area of fern cover on the water, richness, and density of macroinvertebrates. Microbiological analysis of the water detected > 5,700 CFU/mL (rainy season) and 175 CFU/mL (dry season) of heterotrophic bacteria and was positive for total thermotolerant coliforms. The S. biloba cover on the water surface was 100% in the rainy and 30% in the dry season. In the rainy season, 142 macroinvertebrates were identified, divided into 12 morphospecies, with a density of 434 individuals/m3. In the dry season, there were 419 individuals in 14 morphospecies, with a density of 2,076 individuals/m3 exhibited. The highest species density recorded in the rainy season was for Chironomidae sp.1 (Diptera) (57.71%) and Odonata Zygoptera sp.1 (17.44%), and in the dry season, Chironomidae sp.2 (73.98%) followed by Gerromorpha sp.1 (Hemiptera), with 9.54%. The Sørensen similarity index between the two seasons was 53.84%. The higher density of Gerromorpha sp.1 in the dry season may indicate an increase in environmental integrity.

As baixas taxas de sobrevivência de adultos (26%) alimentados com Azolla sp. e de ninfas (40%) e adultos (30%) em L. natans indicam que estas plantas podem representar recursos alimentares alternativos. Experimentos com P. stratiotes e S. auriculata dentro de gaiolas flutuantes, no campo, sem P. acuminata, resultaram num aumento do peso fresco das plantas (51-64%). Com 20 gafanhotos (ninfas e adultos) houve decréscimo de peso (40-45%). Estes dados reforçam o potencial dc P. acuminata como agente de controle biológico de macrófitas aquáticas específicas.

RESUMO A possibilidade do uso de herbicidas em ecossistema aquático para controle de macrófitas quando em condições de desequilíbrio levou à necessidade de estudos que avaliam a concentração de efeito que seja eficiente e ecologicamente equilibrada, sem causar maiores impactos aos organismos não alvo e ao ecossistema aquático. O glifosato é o princípio ativo de alguns herbicidas e é conhecido pela sua eficácia, amplo espectro de ação e baixa toxicidade. Neste trabalho foi investigada a menor concentração de efeito para controle da Eichhornia crassipes e da Salvinia sp em experimentos realizados em triplicata e observados pelo período de 20 dias após aplicações de glifosato nas concentrações de 6,25; 12,5; 25,0; 50,0 e 100 L.ha-1. Como resultado, verificou-se que apenas a concentração de 100 L.ha-1 apresentou diferença significativa de efeito comparada ao controle. O efeito ao final do vigésimo dia foi superior a 90%, tornando-se aparente a partir do décimo dia. Existiu uma pequena diferença na sensibilidade entre as espécies, no entanto, a concentração de efeito foi semelhante. A dose de 100 L.ha-1 impediu a ocorrência de rebrota, no prazo de 30 dias, e causou efeito residual pobre em espécies vegetais inseridas no ambiente após a aplicação do herbicida.

The selection of plant species for phytoremediation activities is very important in the conservation of soil, water, plant, and animal life to create a conducive environment within a community or ecosystem. Plant survival is one indication for the selection of phytoremediation plants. This study aims to determine the survival of some plants in void areas of coal mining. Types of plants used are surface water plants species and the edge of void plant species. The plants of surface water area consisting of Kiambang (Salvinia sp.), Enceng gondok (Eichornia crassipes), Genjer (Limnocharis flava), and Kangkung (Ipomoea aquatica). The plants which planted on edge of void were purun tikus (Eleocharis dulcis) and Bamban (Donax canniformis). Time of observation time was 6 months. Data were analyzed using a tabular matrix that contained the percentage of plant life/period time. The growth of the plant is specifically defined according to the color visibility and the development of plant form. The results of the study found that the highest surface survival species were Kiambang (Salvinia sp.) and Kangkung (Ipomoea aquatica). Both of them still survive for 6 months of observation. The growth percentage of these two plants at the end of the observations are 36% and 20% respectively. Enceng gondok (Eichhornia crassipes) has a survival for 4 months. Whole water plant growth was depressed by indications of death, tendencies to yellowish-brownish or blackish, and smaller body parts. Purun tikus (Eleocharis dulcis) and Bamban (Donax canniformis) grown on the edge of voids have a high survival. Both of them showed ≥95% survival at the end of observation time.

ABSTRACTAquatic plants are important part of aquatic ecosystem that can be used as an phytoremidiation agent, trapping organic matter in eutrophic waters as well as cleaning and controlling heavy metal pollution, pesticides and oil. The aim of research to assess the ability of some aquatic plants to organic matter and phosphate reduction for improve water quality. Research conducted at the Greenhouse of Institution Research for Fishes Resources Rehabilitation in May 2016. The study using factorial completely randomized and all treatment were conducted in triplicate. Aquatic plants are used Azolla sp., Spirodela sp., Duckweed (Lemna sp.), Salvinia sp., Water lettuce (Pistia sp), and water hyacinth (Eicchornia crassipes). Water media used are high stock solution of organic matter derived from fish farming waste water containing undigested, food, faeces and urine of fish. Water sampling was conducted on day 0 (T0), 2nd (T2), 5th (T5) and 9th (T9) after planting. The results showed that the total organic matter) and P-PO4 significantly different based on day of sampling, while the aquatic plant treatment significantly different at P-PO4 concentration, but not significantly different from the organic matter. However, based on the percentage change showed that the wood lettuce (Pistia sp) capable of lowering the BOT and P-PO4 as much as 55.52% and 60.62%, and the water hyacinth can lower both BOT and P-PO4 as much as 23.38 % and 92.68%. Relative growth rate (RGR) was higher in the aquatic plants that tend to be small as Spirodela sp, Lemna sp and with doubling time (DT) is relatively short. Water hyacinth plants tend to have a lower RGR values and DT are relatively long. The value of RGR and DT related to the availability of nutrients.Keywords: Aquatic Plants, Water Quality, Relative Growth Rate (RGR), Doubling Time (DT)ABSTRAKTumbuhan air merupakan bagian penting dari ekosistem perairan yang dimanfaatkan sebagai agen fitoremediasi, perangkap bahan organik di perairan eutrofik serta membersihkan dan mengontrol pencemaran logam berat, pestisida dan minyak.

The kinetics of oxygen consumption related to mineralisation of 18 taxa of aquatic macrophytes (Cyperus sp, Azolla caroliniana, Echinodorus macrophyllus, Eichhornia azurea, Eichhornia crassipes, Eleocharis sp1, Eleocharis sp2, Hetereanthera multiflora, Hydrocotyle raniculoides, Ludwigia sp, Myriophyllum aquaticum, Nymphaea elegans, Oxycaryum cubense, Ricciocarpus natans, Rynchospora corymbosa, Salvinia auriculata, Typha domingensis and Utricularia foliosa) from the reservoir of Piraju Hydroelectric Power Plant (São Paulo state, Brazil) were described. For each species, two incubations were prepared with ca. 300.0 mg of plant (DW) and 1.0 L of reservoir water sample. The incubations were maintained in the dark and at 20 ºC. Periodically the dissolved oxygen (DO) concentrations were measured; the accumulated DO values were fitted to 1st order kinetic model and the results showed that: i) high oxygen consumption was observed for Ludwigia sp (533 mg g-1 DW), while the lowest was registered for Eleocharis sp1 (205 mg g-1 DW) mineralisation; ii) the higher deoxygenation rate constants were verified in the mineralisation of A. caroliniana (0.052 day-1), H. raniculoides (0.050 day-1) and U. foliosa (0.049 day-1). The oxygen consumption rate constants of Ludwigia sp and Eleocharis sp2 mineralisation (0.027 day-1) were the lowest. The half-time of oxygen consumption varied from 9 to 26 days. In the short term, the detritus of E. macrophyllus, H. raniculoides, Ludwigia sp, N. elegans and U. foliosa were the critical resources to the reservoir oxygen demand; while in the long term, A. caroliniana, H. multiflora and T. domingensis were the resources that can potentially contribute to the benthic oxygen demand of this reservoir.

Full textAbstract:
Lebak swamp weeds such as Kayambang (Salvinia molesta) grow abundantly. They can be used as compost, which effectively improves soil fertility, increasing nutrients N, P, and P K quickly and environmentally friendly. The effectiveness of compost fertilizer needs to be increased by adding indigenous microbes as decomposers and biological agents to control plant diseases. The activities carried out to empower horticultural farmer groups on sandy land in Tanjung Pinang Village, Palangka Raya are through socialization, training in composting with three types of antagonist fungus Trichoderma sp. (Trichocompost), facilitate the procurement of weed chopping machines, assist farmers in horticultural crop cultivation, and increase farmers' independence in self-supporting organic fertilizers. The use of Kayambang as Trichocompost with microbial decomposers and indigenous biological agents is new knowledge for partner farmers. The application of Trichocompost on the demonstration plots shows that eggplant plant growth and yields are excellent, meaning that Trichocompost can improve the fertility of sandy soils. Farmers participating in the training stated that the use of Trichocompost could reduce farming costs because it can substitute for manure that has been used by farmers and can meet the self-help needs of organic fertilizers. Participants wanted an advanced mentoring program because the farmers had not yet mastered the isolation or propagation of biological agents and decomposer microbes.

Full textAbstract:
In this paper we evaluated the population dynamics and obtained estimates of the net primary production of the aquatic macrophyte Nymphaea rudgeana in an arm of the Itanhaém River (São Paulo State, Brazil). This species presents, in the studied area, a broad seasonal variation of biomass. As from November (13.1 g DW/m²) we observed a gradual increase of biomass that reached a maximum in February (163.1 g DW/m²). Then, the biomass decreased, maintaining low levels until a new growth period. The reduction of biomass is associated to the development of floating aquatic macrophytes (Pistia stratiotes and Salvinia molesta) and, subsequently to environmental factors (higher salinity values) that are unfavorable to their development. The net primary production of N. rudgeana was estimated from the biomass data, and the annual productivity value was estimated between 3.02 and 3.82 t/ha/year.

This study presents a kinetic model of oxygen consumption during aerobic decomposition of detritus from seven species of aquatic macrophytes: Cabomba furcata, Cyperus giganteus, Egeria najas, Eichhornia azurea, Salvinia auriculata, Oxycaryum cubense and Utricularia breviscapa. The aquatic macrophytes were collected from Óleo Lagoon situated in the Mogi-Guaçu river floodplain (SP, Brazil). Mineralization experiments were performed using the closed bottles method. Incubations made with lake water and macrophytes detritus (500 mL and 200 mg.L-1 (DM), respectively) were maintained during 45 to 80 days at 20 °C under aerobic conditions and darkness. Carbon content of leachates from aquatic macrophytes detritus and dissolved oxygen concentrations were analyzed. From the results we concluded that: i) the decomposition constants differ among macrophytes; these differences being dependent primarily on molecular and elemental composition of detritus and ii) in the short term, most of the oxygen demand seems to depend upon the demineralization of the dissolved carbon fraction.

Com o objetivo de analisar o potencial de uso do carfentrazone-ethyl no controle das principais plantas daninhas aquáticas no Brasil, foi instalado um experimento em vasos com água. Utilizaram-se os seguintes tratamentos herbicidas (g i.a. ha-1): carfentrazone-ethyl a 15, 30 e 60; glyphosate a 4.536; 2,4-D a 4.690; imazapyr a 1.250; e uma testemunha sem herbicida. Esses tratamentos foram testados nas seguintes espécies: Eichhornia crassipes, Salvinia auriculata, Pistia stratiotes, Myriophyllum aquaticum, Brachiaria arrecta, Hydrocotyle umbellata, Typha sp. e Echinochloa polystachya. As avaliações foram efetuadas aos 7, 14, 21 e 28 dias após os tratamentos. Os resultados mostraram que o carfentrazone-ethyl foi eficiente no controle de E. crassipes (maior dose) e P. stratiotes (duas maiores doses), com efeito supressivo sobre S. auriculata. Foi observado que nas outras plantas daninhas estudadas não houve eficiência de controle.

Assim, nosso estudo objetivou fornecer um panorama da associação entre Oligochaeta e macrófitas, em ambientes aquáticos continentais brasileiros, por meio de uma revisão da literatura junto a um inventário de espécies associadas a macrófitas aquáticas em lagoas marginais da represa Ribeirão das Anhumas (Américo Brasiliense-SP). Na revisão, analisamos 10 artigos, nos quais obtivemos dados sobre 41 espécies. Amostramos, ainda, cinco gêneros de macrófitas, Egeria, Salvinia, Utricularia, Eleocharis e Ceratophyllum, de agosto e dezembro de 2012 e em março e abril de 2013, na represa Ribeirão das Anhumas. Registramos 21 espécies de Oligochaeta associadas a essas macrófitas. Com os dados obtidos na revisão junto ao inventário da represa Ribeirão das Anhumas, evidenciamos o total de 41 espécies associadas a macrófitas aquáticas, com maior riqueza da família Naididae (93,33%), seguida por Opistocystidae (4,44%) e Alluroididae (2,22%). Nosso estudo inventariou cerca de 48% da diversidade de Oligochaeta registrados em ecossistemas continentais no Brasil, destacando, assim, a importância das macrófitas como recurso para esses invertebrados, principalmente para a família Naididae.

Infernão Lake, located within the Jataí Ecological Station in Luiz Antônio Municipal district (São Paulo State, Brazil), is one of the most typical ox-bow lake of the Mogi-Guaçu River, and it presents, as the main feature, its great quantity of aquatic macrophytes, whose intensive development, in the last years practically covered the whole mirror of water. With the purpose to point out the composition and to establish the relative participation of the phytophilic zoocoenosis that inhabits the different macrophytes of that lake, a collection program of the main vegetation stands was established. The collections, were carried out randomly, during dry season (1994), in stands of Salvinia auriculata, Utricularia sp., Cabomba piauhyensis, Eichhornia azurea and Scirpus cubensis being used specific methodology for each vegetable type. The analysis of the different macrophytes showed the presence of 4,130 macroinvertebrates of 28 families, in which Chironomidae (Diptera) and Naididae (Oligochaeta) were the most representative, contributing on the average with 51% and 25% of the total fauna. Asheum, Beardius, Chironomus, Goeldichironomus, Parachironomus and Polypedilum were the most abundant Chironomidae genera. Species of the genus Dero (Dero) and D. (Aulophorus) represented the most typical Naididae of the phytofauna. With clear faunistic gradient from the shore to the center of the lake, the taxocoenosis indicated low similarity (PSc < 50%), evidencing its own characteristics of each biotope. On the contrary, there was a high similarity (PSc > 60%) among the associated communities on different vegetables, when grouped into feeding guilds, with expressive participation, in most of the macrophytes, of the collector-gatherers category, except on S. auriculata, whose predators (> 50%) and collector-filterers (> 20%) dominance turned that zoocoenosis distinct from the others.

O objetivo deste estudo foi avaliar a eficiência do herbicida fluridone no controle de plantas aquáticas submersas (Egeria densa, Egeria najas e Ceratophyllum demersum) que ocorrem no reservatório da Usina Hidrelétrica Eng. Souza Dias (Jupiá), região noroeste do Estado de São Paulo. A pesquisa, que consistiu de aplicações de fluridone, foi conduzida em lagoas marginais do rio Tietê, denominadas Flórida e Barrenta. As lagoas foram divididas em faixas, cada uma delas representando um tratamento. As faixas das lagoas receberam uma aplicação inicial de fluridone, procurando-se atingir a concentração de 20 ppb. As aplicações subseqüentes foram dimensionadas para recompor e/ou manter esta concentração, sendo realizadas sempre com o auxílio de uma barra de aplicação munida de três mangueiras, com pontas injetoras submersas na água, em três profundidades (0,2, 0,6 e 1,2 m). O volume de aplicação foi mantido próximo a 54 l ha-1 de calda. Foram feitas avaliações visuais dos sintomas de fitointoxicação nas três espécies estudadas, assim como avaliação da biomassa. Nas condições da pesquisa, o fluridone controlou as macrófitas submersas Egeria najas e Egeria densa; quando cessou o efeito do fluridone, aconteceu a reinfestação de Egeria densa e Egeria najas; e não houve controle de Ceratophyllum demersum nem das espécies não-alvo, como Salvinia auriculata, Ipomoea spp., Merremia sp., Typha latifolia e Cyperus spp.

Foram criados mesocosmos de lagoa para avaliação do efeito de glifosato a organismos não alvo, quando utilizado para o controle de Eichhornia crassipes (Mart.) Solms (1883) e Salvinia sp., macrófitas aquáticas flutuantes. Foi utilizada a formulação comercial Roundup Original®. Avaliou-se o efeito sobre bactérias por meio de ensaios de determinação de coliformes totais, Escherichia coli e contagem de bactérias heterotróficas; sobre fitoplâncton e perifíton; e sobre caramujos e peixes. Ocorreram flutuações na comunidade bacteriana com rápido reestabelecimento, sem consequências consideráveis para a qualidade da água, por não causar alterações na comunidade geral, nem de patógenos. O fitoplâncton e perifíton apresentaram redução da riqueza de espécies e diversidade de Shannon, elevação da densidade de organismos, porém não significativas e alterações na abundância relativa das famílias das espécies. Os peixes e caramujos ficaram por aproximadamente vinte dias sem reproduzir, a partir de quando voltaram a reproduzir e crescer. Os experimentos foram conduzidos com cobertura total de macrófitas no espelho d’água e mostraram que é possível o uso da formulação em ambientes com crescimento descontrolado de macrófitas aquáticas flutuantes, na concentração testada e com controle do processo de aspersão, sem causar efeito significativo aos organismos não alvo avaliados. As alterações não significativas podem ser potencializadas com o uso recorrente de herbicidas, além da possibilidade de seleção de espécies resistentes dos organismos alvo.

Full textAbstract:
ABSTRACT The females of Mansonia are voraciously hematophagous. The spiracular apparatus of the immature, larval, and pupal forms is adapted to perforate submerged aquatic vegetation, from whose aeriferous aerenchyma they obtain the oxygen necessary for breathing. The proliferation of aquatic plants, in some cases linked to anthropic modifications that reduce water flow and/or increase organic matter content, may therefore contribute to the spread of these mosquitoes. This study aims to assess the presence of immature individuals of Mansonia in different aquatic plants of the Madeira River basin in 10 lentic and lotic environments and correlate their population density with abiotic factors such as water pH, dissolved O2, conductivity, and temperature. The sampling lasted from February 2016 to June 2018, a 29-month period during which 31,287 specimens belonging to the genus Mansonia were captured. Of the 12 species of macrophytes inspected, Eichhornia crassipes made up 70.1% of the samples. Lentic environments accounted for 58.9% of the samples and lotic environments for 41.1%. Immature individuals were most commonly found on Eichhornia crassipes, with this plant accounting for an average of 96.2% of all individuals, with a percentage ranging between 58.2% and 77.1% in different breeding areas. Only at the Foz do Igarapé Jirau site was a different distribution observed, with the number of aquatic plants more nearly equal: 83.3% of the larvae were found in Eichhornia crassipes, 9.2% in Ceratopteris pteridoides, 3.6% in E. azurea, 2.0% in Salvinia sp., and 1.9% in Pistia sp. The greatest richness was found in Iguapé do Raul. Concerning the larval/plant relationship, although less frequent, E. azurea had a higher larval density of Mansonia spp. It is important to emphasize that this finding may indicate a possible selection for this plant. Egg deposition by Mansonia spp. was more abundant in sample areas with Eichhornia crassipes and Pistia sp. The number of specimens collected was positively correlated with temperature, pH, and conductivity. These correlations showed a marked increase in the rainy season. Therefore, we were able to establish preliminary parameters of how environmental changes influence the ecology of this important genus of mosquitoes, the species of which are critical disease vectors.

Full textAbstract:
Abstract The fossil record of Marsilea is challenging to assess, due in part to unreliable reports and conflicting opinions regarding the proper application of the names Marsilea and Marsileaceaephyllum to fossil leaves and leaflets similar to those of modern Marsilea. Specimens examined for this study include material assigned to Marsileaceaephyllum johnhallii, purportedly the oldest fossil record of a Marsilea-like sporophyte from the Lower Cretaceous of the Dakota Formation, Kansas, U.S.A.; leaves and leaf whorls of the extinct aquatic angiosperm Fortuna from several Late Cretaceous and Paleocene localities in western North America; and leaves and leaflets resembling Marsilea from the Eocene Green River Formation, Colorado and Utah, U.S.A. Literature on the fossil record of Marsilea was also reviewed. As a result, several taxonomic changes are proposed. Marsileaceaephyllum johnhallii is reinterpreted as an aquatic angiosperm that shares some architectural features with the genus Fortuna, although Marsileaceaephyllum is here maintained as a distinct genus with an emended diagnosis; under this reinterpretation, the name Marsileaceaephyllum can no longer be applied to sporophyte organs with affinities to Marsileaceae. Three valid fossil Marsilea species are recognized on the basis of sporophyte material that includes characteristic quadrifoliolate leaves and reticulate-veined leaflets: Marsilea campanica (J. Kvaček & Herman) Hermsen, comb. nov., from the Upper Cretaceous Grünbach Formation, Austria; Marsilea mascogos Estrada-Ruiz et al., from the Upper Cretaceous Olmos Formation, Mexico; and Marsilea sprungerorum Hermsen, sp. nov., from the Eocene Green River Formation, U.S.A. The species are distinguished from one another based on leaflet dimensions. Leaves from the Eocene Wasatch Formation, U.S.A., are transferred from Marsileaceaephyllum back to Marsilea, although not assigned to a fossil species. Finally, an occurrence of Marsilea from the Oligocene of Ethiopia is reassigned to Salvinia. A critical evaluation of the fossil record of Marsilea thus indicates that (1) the oldest fossil marsileaceous sporophytes bearing Marsilea-like leaves are from the Campanian; (2) only four credible records of sporophyte material attributable to Marsilea are known; and (3) the oldest dispersed Marsilea spores are known from the Oligocene.

Full textAbstract:
Temnothorax is a large myrmicine ant genus with a range spanning the northern hemisphere, including the northern half of the Neotropics. Many of the Neotropical species were originally placed in the now defunct genus Macromischa. Recent molecular work has revealed that distinct lineages of Neotropical Temnothorax have arrived by evolutionary convergenceat a morphological syndrome with characteristics that were used to diagnose the former genus Macromischa. One such lineage is the salvini clade, which in this study is redefined to contain 63 species, 35 of which are described as new. A key to all species of the salvini clade based on the worker caste is provided; additionally, a worker-based key to all clades of the New World is provided. The following species are redescribed: T. albispinus (Wheeler), T. androsanus (Wheeler), T. annexus (Baroni Urbani), T. augusti (Baroni Urbani), T. aztecus (Wheeler), T. ciferrii (Menozzi & Russo), T. flavidulus (Wheeler & Mann), T. fuscatus (Mann), T. goniops (Baroni Urbani), T. huehuetenangoi (Baroni Urbani), T. ixili (Baroni Urbani), T. leucacanthus (Baroni Urbani), T. nigricans (Baroni Urbani), T. ocarinae (Baroni Urbani), T. pastinifer (Emery), T. pergandei (Emery), T. politus (Smith), T. pulchellus (Emery), T. rugosus (Mackay), T. salvini (Forel), T. schwarzi (Mann), T. skwarrae (Wheeler), T. subditivus (Wheeler), T. tenuisculptus (Baroni Urbani), T. terricola (Mann), T. terrigena (Wheeler), T. torrei (Aguayo).

The aim of this work is to assess the morphological characteristics and parameters of biomass production, such as fresh and dry matter weight (FMW and DMW, g/plant), yield of dry matter (YDM) in terms of ton/ha, essential oil content (EOC, mL/100 g) and yield of essential oils (YEO) expressed as L/ha of the following plants Salvia verbenaca, Salvia argentea, Salvia lavandulifolia, Salvia pratensis, Salvia sclarea, Salvia triloba and Salvia officinalis. Except for Salvia argentea (S2) all other species have adapted to the south Brazilian climate conditions, with morphological differences among the species evaluated. In terms of DMW and YDM, S. officinalis was found to be the most productive species with 445.83 g/plant and 11.14 ton/ha. The higher essential oil content and yield was observed for S. officinalis, affording 1.99 mL/100 g and 221.74 L/ha, respectively. Chemical characterisation of the essential oils obtained from hydrodistillation was performed through GC and GC/MSD analyses, which revealed for most of the species studied, α e β-thujone, camphor and 1,8-cineole as major compounds, apart from S. sclarea, for which linalool, linalyl acetate and α-terpineol were the major components.

ABSTRACT In this study, petiol anatomy of 17 Salvia sp. taxa were compared statistically. In all the studied taxa, some differences were found in the petiole shape, number of vascular bundles and the presence of chlorenchyma. Anatomical variations in 17 Salvia taxa have been investigated by means of numerical methods (Analysis of variance and Pearson correlation). By the analysis of the investigated taxa from 17 leaf anatomy related characters, it has been determined that epidermis width and trachea diameter are the best character pairs which represent the variations in them. It has been also found that the results from numerical analysis of the leaf anatomy characters can provide additional evidences that correspond to the anatomy for the recognition of the taxa.

Full textAbstract:
A new definition for the genus Moribaetis Waltz & McCafferty 1985 is given. Its type species, Moribaetis maculipennis (Flowers 1979) is redescribed based on male and female imagoes reared from larvae near the type locality in Panama. Larvae, formerly wrongly attributed to Moribaetis salvini (Eaton 1885), and a male imago, formerly wrongly attributed to Moribaetis macaferti Waltz 1985, belong to a new species Moribaetis latipennis sp. n., which is described here based on a male imago reared from larva in Panama. Both species, M. maculipennis and M. latipennis sp. n., are distinct from M. salvini, which is known as a single male imago (lectotype) from Costa Rica. All other species, formerly attributed to Moribaetis, are excluded from this genus; a new combination Caribaetis macaferti comb. n. is proposed for the species originally described as Moribaetis macaferti Waltz (in Waltz & McCafferty) 1985, and a new combination Baetis (Rhodobaetis) mimbresaurus comb. n. is proposed for the species originally described as Moribaetis mimbresaurus McCafferty 2007.

Full textAbstract:
Abstract Sage is medicinal plant, known for its antioxidant and anti-inflammatory effects. Eight extract samples were tested in this study: extract from Salvia officinalis L. varieties from two different geographical localities (Jaslovské Bohunice and Pobedim, Slovakia), Salvia officinalis L., variety “bicolor”, Salvia officinalis L., variety “purpurescens”, Salvia apiana, Salvia divinorum, and two callus cultures of Salvia sclarea L. and Salvia aethiopis L. The highest values for composite parameters were observed for extract from Salvia apiana. It can be concluded that prepared sage extract samples are rich on polyphenolic acids (2 950±265 μg.mL−1 GAeq.) and amines (197±5.50 μg.mL−1 TRPeq.). HPLC analysis confirmed the dominant content of rosmarinic acid in the extracts; the highest content was detected in the Salvia apiana extract (1 120±15 μg.mL−1). Extract from Salvia apiana expressed too the highest antioxidant activity (1 710 – 4 669 μg.mL−1TEAC). Similarly, the highest inhibition activity was observed for this extract on thrombin (57±3.3 %) and on other proteinases (over 80 %). Spearman correlation analysis and PCA analyses revealed a coherence between antioxidant activity of samples and their content of rosmarinic acid as well as inhibitory activity towards particular proteases, and revealed the significance of thiol based secondary metabolites. Cluster analysis demonstrates the differences of Salvia apiana extract from extracts of S. officinalis L., the group of S. divinorum extract and from callus cultures.

Full textAbstract:
Background: During a prospecting revision of Salvia collections at IEB, MEXU and XAL herbaria for Flora of Veracruz, undetermined specimens, or misidentified either as S. nana or S. prunelloides, not referable to any known species were identified.
Hypotheses: The morphological characters of these specimens match with those of Salvia subg. Calosphace sect. Farinaceae and support them as an undescribed species.
Taxon: Lamiaceae, Salvia sp. nov.
Study site: Central portion of the state of Veracruz.
Methods: Botanical explorations were conducted in the two general areas in which the putative new species has been recorded, new specimens were collected and prepared according to standard procedures. A thorough morphological examination was applied, and the hypothesis was tested contrasting the evidence against specialized taxonomic literature and specimens of the most similar species.
Results: Salvia sp. nov. is vegetatively almost identical to S. nana but lacks the diagnostic floral characters defining the group to which this species belongs, sect. Uliginosae. Floral characters rather match those of sect. Farinaceae, to which is assigned; between the species of this section, it is most similar to S. oblongifolia but clearly differs by vegetative characters (petiole length, absence of axillary leaves, leaf shape, size, pubescence and texture, as well as by having thickened veins).
Conclusions: Morphological and comparative examination contrasting with the species of Salvia justifies the recognition of a new Salvia species, which is here named as Salvia gomezpompae and properly described.

So far, of the 292 known species of solenogasters (Mollusca, Aplacophora), 62 belong to the clade Pholidoskepia Salvini-Plawen, 1978. Of these, only two have an abyssal distribution (3500–6000 m depth). Among Pholidoskepia, Dondersiidae Simroth, 1893 is the most diverse family. This study contributes to the knowledge of this family with the description of one new genus and six new species from the abyssal South Atlantic Ocean: Dondersia ? foraminosa sp. n., Nematomenia divae sp. n., Nematomenia brasiliensis sp. n., Nematomenia ? guineana sp. n., Helluoherpia vieiralaneroi sp. n. and Inopinatamenia (gen. n.) calamitosa sp. n. Specimens were collected during DIVA (Latitudinal Gradients of Deep-Sea BioDIVersity in the Atlantic Ocean) expeditions in the Guinea (DIVA 2 Me 63/2, 2005) and Brazil (DIVA 3 Me 79/1, 2008) Basins. Specimens were characterized based primarily on the sclerites and internal anatomy, which was studied using histology. The importance of the radula and mantle sclerites for taxonomy is emphasized. Amended diagnoses for the family and some genera within this family are provided. This contribution increases the described diversity of Dondersiidae to ten genera and 38 species and highlights the need for more study of solenogasters in the deep sea.
