Abstract:
A potential approach to the preparation of affordable activated hydrochar is the hydrothermal carbonization of biomass wastes. In this study, hydrochar was made by hydrothermally carbonizing corncob wastes and then activating them with sodium hydroxide (NaOH). According to the findings, the adsorption capabilities of hydrochar generated at prolonged retention durations, lesser liquid-to-solid ratios, and elevated temperatures were considerably greater. The hydrochars were then analyzed utilizing a variety of characterization methods, and batch tests involving the sorption of rose bengal dye were carried out under a variety of conditions. According to the findings, activated hydrochar has a specific surface area of 12.794 m2/g. In order to better understand and characterize the process of rose bengal dye adsorption, sorption kinetics, and sorption equilibrium onto the produced hydrochars, sorption kinetics and isotherms were further examined through experimental data fitting. The NaOH-activated hydrochar’s adsorption capacity was 799.9 mg/g, respectively. The objective of this research was to assess the viability of using NaOH-activated hydrochar derived from corncobs as an economical and efficient sorbent for eliminating anionic dyes like rose bengal from aqueous solutions. Additionally, the study sought to investigate how various factors influence its sorption capabilities and to provide insights into the adsorption process through kinetic and isotherm analyses.

Abstract:
Hydrothermal carbonization (HTC) is a prominent thermochemical technology that can convert high-moisture waste into a valuable product (called hydrochar) at a relatively mild treatment condition (180–260 °C and 2–10 MPa). With rapidly growing research on HTC and hydrochar in recent years, review articles addressing the current and future direction of this research are scarce. Hence, this article aims to review various emerging applications of hydrochars, e.g., from solid fuel to soil amendment, from electron storage to hydrogen storage, from dye adsorption, toxin adsorption, heavy metal adsorption to nutrient recovery, and from carbon capture to carbon sequestration, etc. This article further provides an insight in the hydrochar’s working mechanism for various applications and how the applications can be improved through chemical modification of the hydrochar. Finally, new perspectives with appropriate recommendations have been made to further unveil potential applications and its improvement through hydrochar and its modified version.

Abstract:
With the increasing needs of clean water supplies, the use of biomass wastes and residues for environmental remediation is essential for environmental sustainability. In this study, the residues from winery and citrus juice industries, namely grape skin and orange peel, respectively, were first converted to hydrochars by hydrothermal carbonization (HTC) and then a cationic dye (methylene blue) adsorption was studied on hydrochars. Hydrochars from both feedstocks were produced at three different temperatures (180, 220, and 250 °C) and a fixed residence time (1 h) to evaluate the hydrochar’s performance on the dye adsorption. The hydrochars were characterized in terms of their pH, pH at point of zero charge (pHPZC), surface functionalities, and surface area. A batch adsorption study of the dye was carried out with variable adsorbate concentration, pH, and temperature. Two adsorption isotherms namely Langmuir and Freundlich models were fitted at 4, 20, and 36 °C. The thermodynamic properties of adsorption (Gibbs free energy (ΔG), enthalpy (ΔH) and entropy (ΔS)) were evaluated from the isotherms fittings. Results showed that the dye adsorption on both hydrochars was significant and followed Langmuir isotherm. The maximum adsorption capacity on citrus waste hydrochar was higher than the winery waste hydrochar at any corresponding HTC temperature. Although hydrochars showed the lowest surface area (46.16 ± 0.11 and 34.08 ± 1.23 m2/g for citrus and winery wastes, respectively) at 180 °C, their adsorption was the highest, owing to their maximum density of total oxygen functional groups (23.24 ± 0.22 and 32.69 ± 1.39 µmol/m2 for citrus and winery wastes, respectively), which decreased with the increase in HTC temperature. This research shows a sustainable route for the production of highly effective adsorbent materials at lower HTC temperatures from citrus and winery wastes.

Abstract:
The hydrothermal carbonization (HTC) of avocado peel was investigated by varying the reaction temperature, reaction time, and catalyst/feedstock ratio. After the HTC process, there was a drastic change in both the structure and chemical composition of the hydrochar compared to the feedstock. This modification aids hydrochar’s improved fuel characteristics, as seen by a drop in the H/C and O/C ratios, as well as an increase in fixed carbon content. The higher heating value (HHV) increased in the feedstock to a maximum value of 27.15 MJ·kg−1, corresponding to hydrochar, which is obtained at an optimized condition. Notably, the HHV and carbon content of the noncatalytic sample are only higher than those of the feedstock but lower than those of the samples surveyed. The combustion behavior and thermal characteristics of hydrochars show that the HTC of the avocado peel in the presence of FeCl3 catalyst introduces a possible direction of application in converting agro-industrial by-products into fuel.

Abstract:
Cation modified hydrochars were synthesized by hydrothermal carbonization (HTC) of sugarcane bagasse, followed by impregnation of three different cations (Ca, Mg, and Fe) or co-precipitation of Fe3+ and Fe2+. HTC enhanced the hydrochar surface area and increased the enrichment of oxygen functional groups on the hydrochar surface confirmed by FTIR. The oxygen functional groups further improve the adsorption capacity for cations during hydrochar chemical modification. Physical appearance, FTIR and XRF confirmed that Ca2+, Mg2+ and Fe2+ or Fe3+ were well retained in the bagasse-derived hydrochar. The pHpzc values of all chemically modified hydrochars were greater than the unmodified hydrochar or bagasse alone. Modification with different cations improved phosphate uptake capacity. The Fe-modified hydrochar with about 45-50% Fe content showed greater phosphate removal efficiency than Ca- and Mg-modified hydrochars. In addition, hydrochars decorated by impregnation of Fe3+ demonstrated better phosphate removal than ones produced by co-precipitation of Fe3+ and Fe2+. Thus, chemically modified hydrochars could be used as an environmentally alternative adsorbent for phosphate removal from aqueous solutions.

Abstract:
In this study, cassava stem-derived hydrochar was modified with sodium hydroxide (NaOH) treatment, followed by loading of minerals, was used to prepare cation-modified hydrochars with enhanced phosphate removal ability. Cassava stems were converted to hydrochar by hydrothermal carbonization at 240 °C for 60 min, then it was soaked in 2 M NaOH for 3 h. The NaOH-treated hydrochars were then loaded with iron (Fe), magnesium (Mg) and calcium (Ca). The cassava stems and the derived hydrochars were analyzed for carbon, hydrogen, nitrogen and oxygen content, surface morphology and elemental compositions. Methylene Blue Numbers (MBN) measured surface area and porosity, and pH at the point of zero charge (pHpzc) was determined. Modification with Fe, Mg and Ca improved phosphate removal efficiency of the resulting hydrochars. Treatment of synthetic wastewater containing 50 mg P/L at pH 7 with the dosage of 2 g/L of the cation-modified hydrochars for 360 min showed that phosphate removal efficiency of these modified hydrochars were - Fe-modified 81 %, Mg-modified 66 % and Ca-modified 56 %. When the adsorbent dosage increased to 20 g/L, more than 98 % of phosphate was removed by the hydrochars modified with Fe, Ca and Mg. In the same conditions, phosphate removal efficiency was for the NaOH-treated hydrochars - 89 %, hydrochar derived from cassava steam - 69 % and the starting material - 59 %. The phosphate removal ability of these cation-modified hydrochars increased even when initial phosphorus concentration was increased to 100 mg P/L. This work demonstrated that an abundant agricultural residue, cassava stems, can be converted into effective phosphate adsorbents. HIGHLIGHTS Cassava stem were converted to hydrochar by aqueous carbonization at elevated temperature and pressure - hydrothermal carbonization (HTC) Sequential steps of alkali treatment and chemical modification, following HTC, were used to improve the phosphate removal ability of the cassava stem-derived hydrochar Loading of minerals (Fe, Mg and Ca) was a vital way to increase the adsorption of phosphates on hydrochar Phosphorus removal efficiency of Fe-loaded hydrochar was better than Mg- and Ca-loaded hydrochars Cation-modified hydrochars showed good phosphate removal ability over a wider concentration range GRAPHICAL ABSTRACT

Abstract:
Municipal sewage sludge was subjected to a hydrothermal carbonization (HTC) process for developing a hydrochar with high adsorption capacity for water remediation in terms of dye removal. Three hydrochars were produced from municipal sewage sludge by performing HTC at 190, 220 and 250 °C, with a 3 h reaction time. Moreover, a portion of each hydrochar was subjected to a post-treatment with KOH in order to increase the adsorption capacity. Physicochemical properties of sludge samples, raw hydrochars and KOH-modified hydrochars were measured and batch adsorption studies were performed using methylene blue (MB) as a reference dye. Data revealed that both raw and modified hydrochars reached good MB removal efficiency for solutions with low MB concentrations; on the contrary, MB in high concentration solutions was efficiently removed only by modified hydrochars. Interestingly, the KOH treatment greatly improved the MB adsorption rate; the modified hydrochars were capable of capturing above 95% of the initial MB amount in less than 15 min. The physicochemical characterization indicates that alkali modification caused a change in the hydrochar surface making it more chemically homogeneous, which is particularly evident for the 250 °C hydrochar. Thus, the adsorption process can be regarded as a complex result of various phenomena, including physi- and chemi-sorption, acid–base and redox equilibria.

Abstract:
Hydrochar is a carbon-based material that can be used as soil amendment. Since the physical-chemical properties of hydrochar are mainly assigned to process parameters, we aimed at evaluating the organic fraction of different hydrochars through 13C-NMR and off-line TMAH-GC/MS. Four hydrochars produced with sugarcane bagasse, vinasse and sulfuric or phosphoric acids were analyzed to elucidate the main molecular features. Germination and initial growth of maize seedlings were assessed using hydrochar water-soluble fraction to evaluate their potential use as growth promoters. The hydrochars prepared with phosphoric acid showed larger amounts of bioavailable lignin-derived structures. Although no differences were shown about the percentage of maize seeds germination, the hydrochar produced with phosphoric acid promoted a better seedling growth. For this sample, the greatest relative percentage of benzene derivatives and phenolic compounds were associated to hormone-like effects, responsible for stimulating shoot and root elongation. The reactions parameters proved to be determinant for the organic composition of hydrochar, exerting a strict influence on molecular features and plant growth response.

Abstract:
A model hydrochar was synthesized from glucose at 180 °C and its Cu(II) sorption capacity was studied experimentally and computationally as an example of molecular-level adsorbent design. The sorption capacity of the glucose hydrochar was less than detection limits (3 mg g−1) and increased significantly with simple alkali treatments with hydroxide and carbonate salts of K and Na. Sorption capacity depended on the salt used for alkali treatment, with hydroxides leading to greater improvement than carbonates and K+ more than Na+. Subsequent zeta potential and infrared spectroscopy analysis implicated the importance of electrostatic interactions in Cu(II) sorption to the hydrochar surface. Computational modeling using Density Functional Theory (DFT) rationalized the binding as electrostatic interactions with carboxylate groups; similarly, DFT calculations were consistent with the finding that K+ was more effective than Na+ at activating the hydrochar. Based on this finding, custom-synthesized hydrochars were synthesized from glucose-acrylic acid and glucose-vinyl sulfonic acid precursors, with subsequent improvements in Cu(II) adsorption capacity. The performance of these hydrochars was compared with ion exchange resins, with the finding that Cu(II)-binding site stoichiometry is superior in the hydrochars compared with the resins, offering potential for future improvements in hydrochar design.

Abstract:
Citric acid (CA) was used for the hydrothermal carbonization (HTC) of cellulose nanofiber and found to exert remarkable effects on the chemistry and physical aspects of the product distribution. More specifically, the morphology, yield, elemental and proximate composition, chemical functional groups, thermal properties and surface properties of the resultant hydrochars were studied extensively. The morphological properties of the final char were the singularly most surprising and unique finding of this study. The cellulose nanofiber hydrochars were contrasted to hydrochars from bleached softwood pulp, having a similar composition with the former, to pinpoint the role of nano-dimensions. Without the presence of CA, the pulp hydrochar lacked several of the spherical dimensions shown in the nanocellulose; however, and unexpectedly, the presence of CA caused a homogenization of the final product distribution for both samples. Finally, thermally stable and high surface area hydrochars were obtained when the hydrochar was rinsed with acetone.

Abstract:
A capivara (Hydrochaeirs hydrochaeris ), maior roedor, pertence à subordem dos Histricomorfos, os quais caracteristicamente possuem subplacenta. Com o objetivo de descrever o desenvolvimento da placenta durante o terço inicial de prenhez analisaram-se 3 úteros e suas placentas (n=9) e 7 úteros vazios, os quais foram fixados em formol 10% em tampão fosfato, obtidas no Frigorífico Panamby-Porã. Cada placenta foi fixada em formol 10% PBS. Macroscopicamente o útero é duplo, com 1 óstio vaginal da cérvix, e em fêmeas prenhez possui regiões abauladas que representam as placentas, implantadas na face mesometrial, com conexões com a face antimesometrial por tiras esbranquiçadas. As placentas analisadas sinalizavam diferentes idades gestacionais pelo crow-rump dos fetos (11,5mm, 55mm e 58cm). A decídua capsular (3-5 mm) envolve o conjunto placentário e torna-se mais delicada e transparente com o avançar da prenhez. Os embriões estão envoltos pelo âmnio, e ventralmente comunicam-se com a placenta principal pelo cordão umbilical. As seguintes regiões placentárias foram identificadas como, decídua (capsular e basal), placenta vitelínica (visceral e parietal), âmnio, placenta principal e subplacenta. A inversão do saco vitelinico caracteriza-se pela placenta vitelínica visceral e parietal. A placenta principal é discóide e lobulada. Os lóbulos surgem na face fetal e desenvolvem-se em direção ao centro da placenta principal. A imunomarcação positiva da citoqueratina no cinsiotrofoblasto e da vimentina no endotélio dos capilares fetais comprovou a organização do labirinto. A subplacenta esta na interface da placenta principal com a decídua basal, e composta por lóbulos de sinciotrofoblasto citoqueratina positivos, dispostos sobre o eixo de mesênquima intensamente vascularizados. Estes resultados demonstram que a placentação da capivara é semelhante àquela descrita em guinea-pig, paca, cutia e mocó.
Capybara (Hydrochaeirs hydrochaeris), largest rodent, belongs to the suborder of the Hystricomorpha, which characteristically possesses subplacenta. Aiming to describe the development of the placenta during early gestation, it was analyzed seven control and three pregnant uterus and its placentas (n=9), which were fixed in a 10% PBS formol solution; the animals were acquired at the Panamby-Porã abattoir. Gross anatomically, the uterus was doubled presenting one vaginal ostium in the cervix; in the uterus of pregnant females it is observed swelling regions that represents the placenta, which is implanted in the mesometrial face, being connected to the anti-mesometrial face by white streaks. The fetuses crow-rump classification ? 11.5mm, 55mm and 58cm ? signaled different gestational periods. The capsular decidua (3-5 mm) involves the placental set and becomes more delicate and transparent during the pregnancy. The embryos are packed by the amnion, and are ventrally connected to the principal placenta by the umbilical cord. Placental regions were identified: capsular and basal decidua, visceral and parietal vitelline placenta, amnion, principal placenta and subplacenta. The inversion of the yolk sac was characterized by the parietal and visceral vitelline placenta. The principal placenta was discoid and lobulated. The lobules aroused in the fetal face and developed in direction to the center of the principal placenta. The positive immune labeling to citokeratin in the syncytium trophoblast and of vimetin in the capillar endothelium proved a labyrinth formation. The subplacenta aroused along the interface of the main placenta and the basal decidua and it is composed by lobules of positives citokeratin syncytium trophoblast disposed over the well developed vascular mesenchima. These results demonstrate that the placentation of the capybara is similar to guinea-pig, paca, agouti and mocó descriptions.

Resumo: O presente trabalho teve como objetivo selecionar um método para identificação de animais, fornecendo subsídios indispensáveis para a caracterização ou descaracterização de crime, tanto na matança de animais silvestres como torturas de animais domésticos, ambos protegidos por lei, bem como verificar a cristalização da hemoglobina, mais precisamente da oxihemoglobina, em sangue "in natura", com anticoagulante e coagulado de capivaras. Esta é a mais delicada prova das diferenças de constituição química da hemoglobina, pois se acompanha da diferença de estrutura física. Aliado a isto, esta técnica possui baixo custo de implantação, rapidez na obtenção dos resultados, por ser de fácil preparação e manejo. No presente trabalho foram utilizadas preparações modificadas de COSTA (1933). Após a compilação e análise dos dados verificou-se que a quantidade, o tamanho, a cor, o local e o contorno do cristal não estão associados ao sexo do animal e que a quantidade de cristal depende da técnica empregada, sendo a técnica 2 (sangue fresco oxalatado é centrifugado, o sedimento é laqueado pela saponina; junta-se sulfato de sódio, agita-se energicamente e em seguida centrifuga-se durante 10 minutos na velocidade 4 ) a que produz mais cristais. Observou-se também que das técnicas empregadas, nenhuma influenciou o contorno do cristal obtido. Das técnicas utilizadas constatou-se que a técnica de n° 02 é a que produz cristais maiores, com coloração mais intensa (rosa intenso) e com distribuição regular na lâmina. Também .observou-se que a quantidade, o tamanho e a localização do cristal não estão associados à utilização ou não do luto, somente após 48 horas com luto, houve influência na coloração e no contorno dos cristais

Abstract:
A capivara é uma espécie da fauna silvestre que se favoreceu da situação de conversão de áreas florestais para fins agropecuários, tornando-se bastante comum. Tal superpopulação causa conflitos, especialmente em virtude de prejuízos agrícolas e riscos de transmissão de doenças. Entretanto, a espécie apresenta grande potencial zootécnico e econômico, sendo que, aparentemente, o sistema produtivo mais sustentável seria o extensivo. Para fornecer subsídios técnicos a este sistema, torna-se necessário o monitoramento das populações. Um dos métodos mais utilizados para populações de capivaras é o de contagem direta dos animais, utilizada usualmente em ambientes mais abertos, porém pouco eficiente em locais de vegetação mais fechada e para populações mais arredias. O que se buscou testar neste trabalho foi um método de monitoramento alternativo à contagem direta. O trabalho foi realizado em sete áreas, sendo quatro com populações fechadas e três abertas. Semanalmente foram contadas as fezes depositadas durante esse período numa área amostral, contados diretamente os animais e levantados dados sobre flutuação real das populações fechadas. A obtenção de um índice de abundância através da contagem de fezes apresentou um coeficiente de regressão linear melhor que a contagem direta, em comparação com a flutuação real da população, obtida em ambientes fechados. Porém, nenhum dos métodos apresentou resultados satisfatórios que refletissem, no índice, as alterações ocorridas na população. A contagem de fezes mostrou-se satisfatória para separar em faixas de número de indivíduos as diferentes populações e também na aplicação da estimativa populacional baseada na técnica de Índice-manipulação-índice. O trabalho levanta inúmeras questões a respeito da intensidade amostral, de possíveis estudos quanto ao uso do habitat e do grau de confiabilidade dos monitoramentos baseados em contagens diretas.
The capybara is a wild species that would be favored by the conversion of the forest areas to farmlands, becoming abundant. Such overpopulation causes conflicts, especially due to agricultural damages and risks of transmission of illnesses. However, this species presents a great potential in both aspects: zootechnical and economical. As a result, apparently, the most sustainable productive system would be the extensive one. In order to supply technical subsidies to this system, surveying of populations become necessary. One of the survey methods most used in capybara populations is the direct counting that is usually adopted in ecosystems predominantly herbaceous. However, this methodology relies in some problems. It presents low efficiency in dense forested areas as well as in dealing with fearful capybara individuals. Thus, we proposed in this study a surveying method as an alternative to the direct counting one. The work was done on seven areas (four with closed populations and three open). Weekly, the individuals had been counted, as well as the feces deposited in the period on a sample area, besides getting the real data with respect to fluctuation of the closed populations. The attainment of an index of abundance through the feces counting presented a coefficient of linear regression better that the direct counting, in comparison with the real fluctuation of the population, gotten in closed environments. However, none of the methods presented satisfactory results that they reflected, in the index, the occurred alterations in the population. The feces counting revealed satisfactory to also separate in bands of number of individuals the different populations and in the application to estimate populations based in the technique of Index-manipulation-index. The work raises innumerable questions about the sampling intensity, possible studies about the home range use and the degree of trustworthiness of the surveys based on direct countings.

A capivara Hydrochaeris hydrochaeris é um roedor de grande porte e semiaquático. A espécie ocorre em vários ambientes, podendo ocorrer em regiões com alto grau de influencia antrópica. A BR-471 que corta longitudinalmente a ESEC Taim, causa impacto localmente na região, por estar ocasionando prejuízos à fauna e a flora, em função dos atropelamentos de capivaras ao longo da reserva. Nesta região também vem sendo utilizados pesticidas e herbicidas, que podem estar contribuindo com a presença de metais. Estes metais podem se depositar no sedimento e na coluna d’água afetando direta ou indiretamente os organismos. No entanto as capivaras estão sujeitas aos efeitos da bioacumulação destes possíveis contaminantes, adquiridos através da ingestão de plantas contaminadas por metais. Com isso, o objetivo desse trabalho é avaliar os níveis de contaminação por metais pesados em tecidos de capivaras (Hydrochaeris hydrochaeris) mortas por atropelamentos na Br-471 Sul do Rio Grande do Sul. Para determinar as concentrações de metais (Ag, Cd, Cu, Pb, e Zn) em diferentes tecidos (fígado, rim, gordura, músculo) pelo e conteúdo estomacal de capivara, foram realizadas coletas mensais ao longo de um ano. As amostragens dos animais mortos serão feitas através de necropsia, as amostras e serão acondicionadas em tubos de plástico e posteriormente congeladas. Após, essas amostras serão pesadas, secas e digeridas em ácido nítrico e diluídas em água MilliQ. As concentrações de Ag, Cd, Cu, Pb, e Zn serão determinados por espectrofotometria de absorção atômica. Os dados serão expressos como média ± erro padrão. As médias dos metais dos tecidos de machos e fêmeas serão comparadas através de Analise de Variância de duas vias (ANOVA), seguida de teste a posterior de Tukey, com significância de 5%. Os resultados, demonstraram que a concentração de prata foi menor na primavera em relação às outras estações do ano nas amostras (P<0,05), não houve variação significativa (P< 0,05) na concentração de cádmio nas amostras, a concentração de chumbo na primavera foi maior em todas as amostras (P< 0,05), a concentração de cobre no inverno e no outono foi significativamente menor que o verão e a primavera (p< 0,05), a concentração de zinco não teve variação ao longo do ano (P< 0,05). O Cd, Ag e o Pb não tiveram variação significativa ao longo do ano no sedimento (P<0,05), já o Cu foi presente no sedimento na primavera, e o Zn foi maior no outono e inverno. (P<0,05). Os resultados deste trabalho demonstraram que as capivaras estão contaminadas por metais não essenciais na Estação Ecológica do Taim. Além disso, podemos sugerir a utilização de pelo para o monitoramento de contaminação da capivara por metais.
The capybara Hydrochaeris Hydrochaeris is a rodent large and semiaquático. The species occurs in various environments and can occur in regions with high anthropogenic influences. The BR- 471 that cuts along the ESEC Taim, impacts locally in the region, to be causing damage to fauna and flora, according to the roadkill capybaras along the reservation. This region has also been used herbicides and pesticides that may be contributing to the presence of metals. These metals can be deposited in the sediment and the water column affecting directly or indirectly the bodies. However capybaras are subject to the effects of bioaccumulation of these possible contaminants, acquired through eating plants contaminated by metals. Thus, the aim of this study is to assess the levels of heavy metal contamination in tissue capybaras (Hydrochoerus hydrochaeris) killed by being run over in the BR-471 South Rio Grande do Sul. To determine the concentrations of metals (Ag, Cd, Cu , Pb, and Zn) in different tissues (liver, kidney, fat, muscle) and the stomach contents of capybara, monthly samples were taken over a year. Samples of the dead animals will be made through autopsy, samples and will be placed in plastic tubes and subsequently frozen. After these samples are weighed, dried and digested in nitric acid and diluted in MilliQ water. The Ag concentrations of Cd, Cu, Pb, and Zn are determined by atomic absorption spectrophotometry. The data are expressed as mean ± standard error. The means of the metals of male and female tissues will be compared by analysis of two-way variance (ANOVA) followed by Tukey test later, with 5% significance. The results showed that the silver concentration was lower in the spring relative to the other seasons in samples (P <0.05), there was no significant difference (P <0.05) in cadmium concentration in the samples, the concentration lead spring was higher in all samples (P <0.05), the concentration of copper in the winter and autumn was significantly lower than the spring and summer (p <0.05), the concentration of zinc was not variation throughout the year (P <0.05). Cd, Ag and Pb have not changed throughout the year in the sediment (P <0.05), whereas the Cu was present in the sediment in the spring, and Zn was higher in autumn and winter. (P <0.05). These results demonstrated that capybaras are contaminated by non-essential metals in the Taim Ecological Station. In addition, we suggest the use of at for contamination monitoring of the capybara for metals.

Abstract:
O presente trabalho teve como objetivo conhecer os fatores que propiciam as grandes densidades ecológicas de capivaras, através da comparação das dinâmicas populacionais de dois agrupamentos, em diferentes localidades do município de Pirassununga, SP (Campus Administrativo da Universidade de São Paulo – USP/Pirassununga e o Centro de Pesquisa e Gestão de Recursos Pesqueiros e Continentais – CEPTA/Ibama), para que futuramente seja possível propor uma metodologia de manejo que promova o controle populacional dessa espécie no Estado de São Paulo. Para tanto, foi realizado o monitoramento populacional de ambos agrupamentos durante 15 meses, através da contagem direta dos animais, constituindo na principal fonte de informação para determinar as dinâmicas populacionais. Adicionalmente realizaram-se as capturas dos indivíduos de ambas populações pelo uso de bretes fixos, para que fossem feitas as pesagens, sexagens e marcações eletrônicas pelo uso de microchips e assim, conhecer a distribuição etária, bem como a proporção entre sexos. O uso de ceva no interior dos bretes, para a atração dos animais, possibilitou a realização das contagens diretas e das capturas e recapturas. Para a análise das dinâmicas populacionais foram realizadas as comparações descritivas e estatísticas das densidades ecológicas das populações e das respectivas classes etárias, além do cálculo da taxa de crescimento das mesmas. A alimentação em ceva apresentou-se influenciada pela hierarquia de dominância social, o que fez com que apenas as parcelas dominantes fossem capturadas. Percebeu-se, através das capturas, que o número de fêmeas apreendidas foi superior ao de machos nas parcelas dominantes das duas populações. Por meio das observações foram detectados indivíduos satélites e subagrupamentos, cuja ocorrência pode caracterizar um sistema biológico de metapopulação. A comparação descritiva e estatística das densidades ecológicas das populações, bem como a comparação das taxas de crescimento revelaram superioridade populacional do agrupamento do CEPTA/Ibama em relação ao Campus da USP/Pirassununga, provavelmente pelo maior número de picos de acasalamentos observados, os quais possivelmente são influenciados pelo tipo de habitat antropizado e abundante em recursos hídricos presente no CEPTA/Ibama.
The present research aimed the knowledge of the factors that allow the high ecological densities of capybaras through the population dynamics comparison of two capybara groups in the district of Pirassununga, SP (Campus Administrativo da Universidade de São Paulo – USP/Pirassununga and Centro de Pesquisa e Gestão de Recursos Pesqueiros e Continentais – CEPTA/Ibama), intending to propose forward a management methodology for capybara population control in the State of São Paulo. The populations monitoring was carried out through direct count of animals during 15 months, which played the main role to determine the population dynamics. Fixed traps were used to allow the weightings, sex definitions and identification through microchips, and also to know the age distribution and sex ratios. It was used bait inside the traps to attract animals and thus make direct counting and capture possible. To analyze population dynamics it was used the population ecological densities comparisons (statistically and descriptively) and also their rates of increase. It was detected social dominance hierarchy inside the traps, thus only the dominant part of population could be caught. Females represented the majority among captured animals. Satellites individuals and new groups were seen during observations and their existence might characterize a biological system of metapopulation. The descriptive and statistic comparisons of population ecological densities, as well as their rates of increase showed population superiority of CEPTA/Ibama’s group probably for its bigger reproduction effort detected, which possibly receives influence of anthropogenic and water abundant habitats of CEPTA/Ibama.

Abstract:
O habitat natural da capivara é a América Central e do Sul, em áreas que vão desde o Panamá até a Argentina, o que inclui a região Andina. Estes animais são herbívoros, diurnos, semi-aquáticos, gregários e dóceis; eles formam grandes rebanhos e são potencialmente importantes para: a produção de carne de ótima qualidade, couro e óleo, amplamente utilizado na medicina popular. Apesar de seu presuntivo valor econômico, estes animais foram até o momento pobremente estudados, mesmo no que tange às suas características reprodutivas. Neste trabalho, foi dada especial atenção ao estudo macro e microscópico da placenta de termo destes animais, órgão de fundamental importância para o sucesso do desenvolvimento fetal, manutenção da gestação e garantia de expansão dos rebanhos. Foram utilizadas 11 placentas de termo de capivaras (Hydrochaeris hydrochaeris). Nossos resultados mostraram uma placenta vitelina e uma placenta corioalantoidiana coexistindo juntas até o final da gestação, exibindo uma forma discóide irregular e fixada à região mesometrial do útero pelo pedúnculo da placenta. A placenta corioalantoidiana é formada por estruturas irregulares que caracterizam os lobos e lóbulos placentários; à microscopia eletrônica de transmissão a barreira placentária é do tipo hemomonocorial. O principal componente celular da placenta, o trofoblasto, está em grande parte representado pelo sinciciotrofoblasto, tanto nas regiões de trocas, o labirinto que constitui a região lobular, como nos interlóbulos. Na região de trocas o trofoblasto é polarizado, apresenta uma composição de organelas semelhante à encontrada em células com intensa atividade de síntese protéica e endocitose. A análise geral dos componentes vasculares e sanguíneos, materno e fetal da placenta, também sugere que a circulação placentária é do tipo contracorrente. Em todos os aspectos morfológicos estudados, a placenta da capivara foi bastante semelhante à observada em cobaias por outros autores.
South and Central America are the natural habitat of the capybara, in the areas that go from Panama to Argentina, including the Andes region. These animals are herbivorous, diurnal, semi-aquatic, gregarious and docile; they live in large groups and are potentially important for the production of high quality meat, skin and oils, largely utilized in popular medicine. In spite of their economical value for the South and Central America populations, capybaras have not yet been properly studied, not even regarding their reproductive features. In this study, special attention has been given to the macroscopic and microscopic analyses of the mature placenta, an organ of fundamental importance to the fetal development and the maintenance of the gestation. Eleven mature placentas of capybara (Hydrochaeris hydrochaeris) were used. Our results show a vitelline and a chorio - allantoic placenta, coexisting until the end of the gestation, and exhibiting an irregular discoidal shape, fixed to the mesometrial region of the uterus by the stem placenta. The chorio - allantoic placenta is formed by irregular structures that characterize the placental lobes and lobules and, under electron microscopy, the materno - fetal barrier is hemomonochorial. The main cellular placental component is largely represented by the syncytiotrophoblast in the exchange areas of the labyrinth, which form the lobular region, as well as in the interlobular area. In the labyrinthic region the trophoblast is polarized and presents typical organelles of cells, which express intense protein synthesis activity and endocytosis. The general analysis of the vascular and blood components of the placenta was suggestive of a countercurrent placental circulation. Our morphological results also show that the capybara placenta has a similar structure to that found in the guinea pig by other authors.

Abstract:
Muitas espécies de mamíferos selvagens são criadas para produção de carne. No Brasil, a capivara (Hydrochaeris hydrochaeris), a paca (Agouti paca), o cateto (Tayassu tajacu) e a queixada (Tayassu pecari) são criadas comercialmente para este fim, porém são escassas as informações sanitárias a respeito dessas espécies. Assim, o presente estudo teve por objetivo estudar a presença de infecção causada por leptospiras, micobactérias, brucelas e Erysipelothrix spp. em 138 animais dessas quatro espécies, provenientes de nove criadouros e abatidos em estabelecimento com Serviço de Inspeção Federal. Nenhum animal apresentou anticorpos séricos contra brucelas lisas. As capivaras apresentaram a maior freqüência de animais sorologicamente reagentes para leptospiras (54,5%), seguidas das queixadas (39%) e dos catetos (21,7%). O sorovar mais provável mais freqüente para as espécies estudadas foi o Grippotyphosa, seguido do Hardjobovis e do Tarassovi. Das capivaras foram isolados Leptospira santarosai a partir de rim e Mycobacterium xenopi a partir de linfonodo mesentérico. Das queixadas foi isolado Erysipelothrix rhusiopathiae a partir de tonsila. Segundo os bancos de dados Scopus, Pubmed e Cab Abstracts (Ovid), trata-se dos primeiros relatos de isolamento de M. xenopi em capivara e de E. rhusiopathiae em queixada.
Many species of wild mammals are raised for meat production. In Brazil, the capybara (Hydrochaeris hydrochaeris), paca (Agouti paca), collared peccary (Tayassu tajacu) and the white-lipped peccary (Tayassu pecari) are commercially bred, however there is limited sanitary information related to these species. This study aimed to search for the presence of infection caused by Leptospira spp., Mycobacteria spp., Brucella spp. and Erysipelothrix spp. in 138 animals belonging to those species, coming from nine commercial breeders and slaughtered under the Federal Inspection Service. None of these animals presented antibodies against smooth brucellas. The capybaras showed the highest frequency of seropositive animals for leptospirosis (54.4%), followed by the white-lipped peccaries (39%) and the collared peccaries (21.7%). The most frequent serovar was Grippotyphosa, followed by Hardjobovis and Tarassovi. Leptospira santarosai was isolated from the kidneys and Mycobacterium xenopi from the mesenteric lymph nodes of the examined capybaras. Erysipelothrix rhusiopathiae was isolated from the tonsils of one white-lipped peccary. According to the data banks Scopus, Pubmed e Cab Abstracts (Ovid), this is the first report of M. xenopi isolation from capybara and of E. rhusiopathiae from white-lipped peccary.

Abstract:
Foi realizada a pesquisa de anticorpos anti-Toxoplasma gondii, através do teste de aglutinação modificado (MAT), em 68 amostras de soros de capivaras de seis municípios no estado de São Paulo. Anticorpos (MAT?25) foram encontrados em 51 (75%) capivaras examinadas. Dentre estas realizou-se o bioensaio em camundongos, com tecidos do cérebro, coração e língua, de 40 capivaras, sendo obtidos 36 isolados (90%). Não houve associação entre o número de isolados e idade das capivaras (p=0,21), sexo (p=0,58) ou tipo de criação (p=0,62), isto é, criadouros e vida livre, bem como a freqüência de isolamentos e os títulos de anticorpos (p=0,99). A análise de polimorfismo de comprimento dos fragmentos de DNA gerados por enzimas de restrição (RFLP) sobre produtos do locus SAG2 amplificados pela reação em cadeia pela polimerase (PCR) revelou que 20 isolados (55,5%) pertenciam ao genótipo I, 14 (38,9%) ao genótipo III e dois (5,6%) que apresentaram genótipo misto (tipos I e III). Não foi encontrado isolado tipo II. A proporção de isolados tipo I entre as capivaras de vida livre foi maior (p=0,049) do que entre as capivaras provenientes de criadouros. Por outro lado, entre as capivaras de criadouros, a proporção de isolados tipo III foi maior (p=0,041). A maioria dos isolados tipo I (12/20) causou óbito em todos os camundongos infectados e, em nenhum grupo com este isolado, 100% dos camundongos sobreviveram. A maioria dos isolados tipo III (8/14) não matou nenhum camundongo infectado. A freqüência de óbitos em camundongos com genótipo I (86%) foi maior do que o tipo III (44,9%) (p<0,001), enquanto a sobrevida dos camundongos com genótipo III foi significativamente maior que a dos camundongos com genótipo I (p<0,001). Foram encontrados cistos nos cérebros dos camundongos infectados em todos os 36 isolados. A análise genotípica também foi realizada diretamente dos tecidos de 35 das 36 capivaras (homogeneizados de tecidos) das quais houve isolamento pelo bioensaio, usando nestedPCR-RFLP no locus SAG2. Foram caracterizadas 22 amostras (62,8%), 21 delas idênticas aos dos isolados correspondentes. Em uma amostra genótipo misto foi obtido dos tecidos primários e tipo I no isolado. Os genótipos mistos foram confirmados pelo seqüenciamento de DNA dos produtos da nestedPCR obtidos das amostras primárias das capivaras.
Antibodies to Toxoplasma gondii were assayed by the modified agglutination test (MAT) in serum samples of 68 capybaras from six counties in São Paulo state, Brazil. Antibodies (MAT?25) were found in 51 (75%) capybaras examined. Tissues (brain, heart and tongue) of 40 of the seropositive capybaras were bioassayed in mice and 36 (90%) isolates were obtained. There was no statistical association between number of isolates and age (p=0.21), gender (p=0.58) and type of rearing (p=0.62), as well as no association with frequency of isolations and antibody titer distribution (p=0.99). Restriction fragment length polymorphism (RFLP) analysis in PCR-amplified SAG2 locus products revealed that 20 isolates (55.5%) were genotype I, 14 (38.9%) were genotype III and two (5.6%) were mixed genotypes (types I and III). Type II isolate was not found. The proportion of type I isolates in the group of wildlife capybaras was higher (p=0.049) than in the captive rearing group. On the other hand, the proportion of type III isolates was significantly higher in the captive rearing group (p=0.041). Most of the type I isolates (12/20) killed all infected mice and none of those groups had 100% of surviving mice. Most of the mice infected with genotype III isolate survived. The mortality rate in mice infected with genotype I (86%) was higher than the type III (44.9%) (p<0.001) and mice infected with type III isolates survived for longer periods than type I isolates (p<0.001). Tissue cysts were found in mice infected with all 36 isolates. Genotyping was also done directly from the tissue homogenates from the 35 of 36 capybaras using nested-PCR-RFLP analysis on the SAG2 locus. Twenty?two samples (62.8%) were characterized and in 21 the genotypes found were the same as those from the corresponding isolates. In one sample, mixed genotype was detected directly from the primary sample and type I from the mice isolate. The mixed genotype was confirmed by direct DNA sequencing of the nestedPCR products from the capybaras primary samples.

Abstract:
AbstractThe drive towards a low carbon economy will lead to an increase in new lignocellulosic biorefinery activities. Integration of biorefinery waste products into established bioenergy technologies could lead to synergies for increased bioenergy production. In this study, we show that solid residue from the acid hydrolysis production of levulinic acid, has hydrochar properties and can be utilised as an Anaerobic Digestion (AD) supplement. The addition of 6 g/L solid residue to the AD of ammonia inhibited chicken manure improved methane yields by +14.1%. The co-digestion of biorefinery waste solids and manures could be a promising solution for improving biogas production from animal manures, sustainable waste management method and possible form of carbon sequestration.
