2. Morphological diversity of foliar trichomes in Asteraceae from Sand-fields of the Pampa biome, Rio Grande do Sul State, Brazil
RESUMO Asteraceae é a maior família das angiospermas e ocorre predominante em áreas campestres. Este estudo buscou identificar e caracterizar os tricomas foliares de 34 espécies de Asteraceae dos Campos de Areais do bioma Pampa por meio de análises da epiderme (vista frontal e transversal) em microscopia de luz e eletrônica de varredura. Foram identifi

3. A taxonomic synopsis of Cypella (Iridaceae) in Brazil
ABSTRACT A taxonomic synopsis of Cypella (Iridaceae) in Brazil is presented with recognition of 16 species, two of them represented by two subspecies. An identification key to the taxa is provided and species are described and illustrated. New synonyms are indicated, and eight lectotypes, two epitypes and one neotype are designated. Results include distribut

4. Methodology for classification of land use and vegetation cover using MODIS-EVI data
RESUMO Objetivou-se neste estudo verificar a aplicabilidade do uso de séries temporais do sensor MODIS-EVI para o mapeamento do uso do solo e cobertura vegetal no Bioma Pampa no Estado do Rio Grande do Sul. O período de estudo compreendeu os meses de junho de 2013 até junho de 2014. Os procedimentos incluíram a utilização de imagens do Sensor MODIS, da

5. Vegetation Burning in Pampa Biome Altered the Chemical Composition of Rainfall
ABSTRACT Rainfall is one of the primary nutrient inputs to vegetation and its chemical composition is dependent on air quality as falling rain scavenges gaseous and particulate emissions from natural, industrial, and agricultural activities. The objective of this study was to evaluate whether the vegetation burn in a region of the Pampa biome influences the

6. Discovery and characterization of SSR markers in Eugenia uniflora L. (Myrtaceae) using low coverage genome sequencing
Abstract: Eugenia uniflora L. (Myrtaceae) is a tree species widely distributed in South America suffering the effects of the exploitation of natural populations. In this study, we employed low coverage sequencing of the E. uniflora genome for mining of SSR markers. The de novo assembly generated 2,601 contigs with an average length of 1139 bp and spans 3.15

7. Developing a Soil Physical Quality Index (SPQi) for lowlands under different deployment times of no-tillage
ABSTRACT: Soil physical quality in lowlands from the Pampa biome under no-tillage (NT) plays an important role; therefore, this study aimed to establish a soil physical quality index (SPQi) from a minimum data set to detect the effects of different deployment times of NT in an Albaqualf. The comparison of areas with one (NT1), three (NT3), five (NT5) and sev

8. Nutrient Input via Incident Rainfall in a Eucalyptus dunnii Stand in the Pampa biome
ABSTRACT We evaluated the nutrient input via incident rainfall in a Eucalyptus dunnii stand in the Brazilian Pampa biome. During the two-year study, we analyzed nutrient concentrations in incident rainfall (P), throughfall via drip (Pi), and stemflow (Et). Ion concentrations (NO2-, NO3-, PO43- , SO42-, Cl-, K+, Ca2+ , and Mg2+) were determined from the aque

9. Soil Biological, Chemical, and Physical Properties After a Wildfire Event in a Eucalyptus Forest in the Pampa Biome
ABSTRACT Wildfire events cause considerable environmental disturbance but few studies have examined changes in soil properties due to fire. This study aimed to assess the effect of a wildfire event on chemical, physical, and biological properties of the soil in a eucalyptus forest in the Pampa biome. Part of a seven-year-old eucalyptus forest was affected by

10. Visual Evaluation of the Soil Structure under Different Management Systems in Lowlands in Southern Brazil
ABSTRACT The “Visual Evaluation of Soil Structure” (VESS) is a method used primarily to evaluate the soil structural quality of Oxisols in Brazil and secondly for more specific research, consultancy, and teaching purposes. Since the methodology was never applied and compared with laboratory evaluations of physical properties of hydromorphic soils of the

11. NDVI and meteorological data as indicators of the Pampa biome natural grasslands growth
ABSTRACT The present study aimed to characterize the dynamics of NDVI and meteorological conditions, relating both to the annual dynamics of biomass accumulation in natural pastures of the Pampa biome as a way of subsidizing growth modeling. Forage accumulation rate data from a long-term experiment, NDVI data from the MODIS images, and meteorological data me

12. Diversity of Drosophilidae (Insecta, Diptera) in the Restinga forest of southern Brazil
Abstract Although members of Drosophilidae are frequently the topic of ecological studies in Brazil, few have explored Restinga or, until only recently, Pampa biome environments. This study proposes to describe the diversity and temporal variation of the Drosophilidae assemblage from a Restinga forest of Rio Grande do Sul, Brazil. We performed monthly collec
