Este trabalho analisou a influência dos usos da terra no município de Ponta Grossa-PR sobre a temperatura de superfície terrestre. Imagens orbitais multitemporais foram utilizadas para obtenção do uso e cobertura e para geração dos valores de temperatura. A partir dos mapas de uso e cobertura e de classes de temperaturas, realizaram-se os cruzamentos estatísticos dos dados. Análises de coordenadas principais foram executadas para cada ano, a fim de avaliar quais classes de temperatura foram mais bem relacionadas com as diferentes classes de uso. As classes área urbana e solo exposto apresentaram as temperaturas mais elevadas, já as classes floresta e cultivo florestal apresentaram temperaturas menores. Através dos diagramas de ordenação da análise de coordenadas, notou-se a formação de dois grupos principais de classes. Um deles formado por classes mais antropizadas, associado aos vetores de temperaturas maiores, outro com as classes de formações vegetais, associados aos vetores de temperaturas mais brandas. This study examined the influence of land use in the city of Ponta Grossa-PR on the Earth's Surface Temperature. Multitemporal orbital images were used to obtain the usage and coverage, and to generate temperature values. With the use of maps and coverage and temperature classes data crosses were obtained. Main coordinate analyses were performed for each year in order to assess which temperature classes were more significant for the different use classes. Classes urban areas and exposed soil showed higher temperatures, since the forest and forest cultivation classes had lower temperatures. Through the ordering diagrams coordinate analysis, the formation of two major groups of classes was noted. One of them consists of more anthropic classes associated with the vectors of higher temperatures; another with classes of plant formations, associated with the vectors of milder temperatures. 332-344 marfagirl@hotmail.com paulocostafh@gmail.com kellygm77@gmail.com apaandrade@gmail.com Semestral

Mangrove forests have a simple architecture. They shelter a few number of arboreal species that grow in a saline environment subject to tidal activity. The research objective was to evaluate possible interactions between physical-chemical soil attributes and plant-leaf nutrient concentrations of different mangrove species. Different mangrove species growing in the same soil, and the same mangrove species growing in two different soil classes were evaluated as to their leaf nutrient concentration patterns. The study was carried out in mangrove areas of the State of Paraná, southern Brazil, in two distinct soil classes: HISTOSOL THIOMORPHIC Salic sodic and GLEYSOL THIOMORPHIC Salic sodic; and three different species: Avicennia schaueriana, Laguncularia racemosa and Rhizophora mangle. Two subareas were delimited within each area from which soil and leaf samples were collected. Samplings from five individuals of each dominant mangrove species were taken from the soil (0-10 cm deep) under each tree crown projection. The data was submitted to statistical analysis using a set of simple and multivariate analysis in order to determine possible differences among mangrove species leaf nutrient concentrations, and whether these differences might be correlated with the soil attributes or not. The results exposed that the nutritional state of the mangrove species is different and independent form the soil attributes in which they grow. Few correlations were found among leaf nutrient concentrations and soil attributes, suggesting differential selective nutrient uptake among species. Los manglares son bosques de arquitectura simple que albergan pocas especies arbóreas, creciendo en un ambiente salino sometido a la influencia de las mareas. El objetivo de este trabajo fue evaluar las posibles interacciones entre las propiedades fisicoquímicas del suelo y la concentración de nutrientes en hojas de diferentes especies de mangle. Se investigó si las diferentes especies que se desarrollan en la misma clase de suelo tienen concentraciones de nutrientes foliares similares, y si las plantas de mangles de la misma especie que se desarrollan en diferentes tipos de suelos tienen concentraciones foliares similares. El estudio se desarrolló en manglares del Estado de Paraná, sur de Brasil, en dos tipos de suelos diferentes (HISTOSOL TIÓNICO Salino sódico y GLEYSOL TIÓNICO Salino sódico). Se analizaron tres especies vegetales diferentes (Avicennia schaueriana, Laguncularia racemosa y Rhizophora mangle). En cada área se delimitaron dos subáreas para recolectar el suelo y las hojas de cada una de las especies. Se tomaron cinco individuos de cada especie del dosel dominante para recoger hojas y muestras de suelo de 0-10 cm, en la proyección de la copa de los árboles seleccionados. Se realizaron análisis univariados y multivariados para probar si las especies de mangle tienen perfiles nutricionales diferentes, y si existe alguna correlación entre las propiedades del suelo con la composición química de las hojas. Los resultados mostraron que el estado nutricional de las especies de mangle es distinto e independiente de los atributos de los suelos en los que se encuentran. Las concentraciones de elementos en las hojas presentan poca correlación con los nutrientes del suelo, lo que sugiere que la absorción de nutrientes por las plantas es selectiva. Manguezais são florestas de arquitetura simples, abrigando poucas espécies arbóreas, vegetando em ambiente salino e sujeito ao regime de marés. O objetivo desta pesquisa foi avaliar as possíveis interações entre os atributos físico-químicos do solo e a concentração de nutrientes nas folhas de diferentes espécies de mangue. Assim, foi investigado se as diferentes espécies que se desenvolvem sobre a mesma classe de solo apresentam concentrações de nutrientes foliares similares, e se plantas de mangue da mesma espécie que ocorrem sobre diferentes classes de solo apresentam concentrações de nutrientes foliares similares. O estudo foi desenvolvido em manguezais no Estado do Paraná, Sul do Brasil, em duas classes distintas de solo (ORGANOSSOLO TIOMÓRFICO Sálico sódico e GLEISSOLO TIOMÓRFICO Sálico sódico), e três espécies diferentes de plantas (Avicennia schaueriana, Laguncularia racemosa and Rhizophora mangle). Em cada área foram delimitadas duas subáreas para coleta de solo e folhas das espécies. Cinco indivíduos do dossel dominante de cada espécie para coleta de folhas, na projeção da copa das árvores, e amostras de solo de 0-10 cm foram selecionados. Para testar se espécies de mangue apresentam perfis nutricionais distintos e se há correlação entre os atributos do solo com a composição química foliar um conjunto de análises univariadas multivariadas foram realizadas. Os resultados demonstraram que o estado nutricional das plantas é distinto e individualizado, independente dos atributos do solo em que se encontram as espécies. As concentrações dos elementos nas folhas pouco se correlacionaram com os nutrientes do solo, sugerindo absorção seletiva dos nutrientes pelas plantas.

- Abstract
The effluent generated in the beverage industry is rich in organic load, requiring a high degree of treatment of the process water, before returning it to nature. In this context, the main objective of this study is to verify was to evaluate the phytotoxicity of effluent from the beverage industry by root elongation and seed germination of Lactuca sativa L. (lettuce) as well as the correlation of these variables with the Color and COD of the raw and treated effluent. The seed germination and root elongation of 540 lettuce seeds divided into 4 concentrations, one positive control and one negative control, each of which was represented by 3 Petri dishes (replicates) with 15 seeds in each plate were evaluated. The seeds were incubated in the absence of light at a constant temperature of 22 ± 2 ° C for 120 hours. At the end of the exposure period, the results showed that there was no statistical difference between the EC50 root growth and the germination index of the treated and treated effluent and the root elongation index showed significant inhibition according to the method for both the effluent Treated as for the brute. Since the percentage of germination and root growth showed a significant correlation with color and COD, it is possible to conclude the treatment inefficiency of the treatment by advanced oxidative process in the studied effluent.

- Abstract
This work aimed to carry out a first diagnosis of local birds, concentrating in six fragments of Ombrophylous Mixed Forest, using methods adequate to be repeated in subsequent periods. The assessment of birds on long-term may be used as local bioindicator, especially because these areas will be managed in the future. In the sampled area it was registered 124 species from 41 families. Four species listed in the Red Book of Threatened Fauna in the State of Paraná were recorded: Polioptila lactea (Creamy-bellied Gnatcatcher), Mesembrinibis cayennensis (Green Ibis), Accipiter superciliosus (Tiny Hawk) and Leptasthenura striolata (Striolated Tit-Spinetail). When the six forest fragments were assessed using the irregular transects method, it was registered 102 species. The trees survey, carried out by sample plots, resulting in 92 species. The Relative Frequency of wild bird community matrix and its sub-group of forest specialist birds presented significant correlation with the Coverage Value of the tree community (DBH ≥ 10cm).

- Abstract
Pulp and paper mill wastewater (PPMWW) contains high concentrations of recalcitrant compounds that cause toxicity to organisms. Advanced oxidation processes (AOPs) have the ability to degrade these compounds and reduce overall toxicity. Physicochemical characterization and Lactuca sativa toxicity test were conducted to compare the effectiveness of two post-treatments: UV/H
2 O2 and photo-Fenton. A comparison of four phytotoxicity indexes was carried out. PPMWW from a Brazilian treatment plant was characterized by high values of phenols, color, integrated spectral area (ISA), and chemical oxygen demand (COD), and caused significant inhibition to seedling development. The use of both post-treatments allowed the removal of over 75% of phenols, color, ISA, and COD. Although UV/H2 O2 was more effective in removing phenols and ISA, photo-Fenton better reduced phytotoxicity. The most sensitive phytotoxicity indexes were RGIC0.8 and GIC80% , whereas SGC0 , REC-0.25 and REC-0.50 better showed the effectiveness of the post-treatments. We suggest the combined use of two phytotoxicity indexes: one that evaluates the effects on seed germination and, another, on root elongation, e.g., SGC0 and RGIC0.8 . Additionally, we recommend the use of ISA for monitoring programs of wastewater treatments because it is a cost-effective approach that allows narrowing down the search and identification of compounds present in complex mixtures., (Copyright © 2020 Elsevier Inc.
