1. Evaluation of the Concentration of Cu, Zn, Pb and Cr in Different Fish Species from the São Gonçalo Channel in Pelotas-RS, Brazil
The objective of this study was to evaluate the concentration of Cu, Zn, Cr and Pb in different species of fish collected in the estuarine and limnic regions of the São Gonçalo channel, located in the Patos-Mirim lagoon complex in the coastal plain of Rio Grande do Sul State (Southern Brazil) during 2013 (autumn, winter and spring) and 2014 (summer).

2. Epiphytic ferns in swamp forest remnants of the coastal plain of southern Brazil: latitudinal effects on the plant community
ABSTRACT Community structure and spatial distribution of epiphytic ferns in swamp forest remnants along the coastal plain of the state of Rio Grande do Sul were analyzed. A total of 440 trees were sampled in fifty-seven 10 x 10 m plots. Each phorophyte was divided into five ecological zones (strata), where all species of epiphytic ferns were recorded. A tota

3. Cordão Formation: loess deposits in the southern coastal plain of the state of Rio Grande do Sul, Brazil
ABSTRACT Loess consists of silt-dominated sediments that cover ~10% of the Earth's surface. In southern South America it occurs in Argentina, Bolivia, Paraguay and Uruguay, and its presence in southern Brazil was never studied in detail. Here is proposed a new lithostratigraphic unit, Cordão Formation, consisting of loess deposits in the southern Brazilian

4. Stichelia pelotensis (Lepidoptera, Riodinidae): conservation, notes, and rediscovery of an endangered butterfly from southern Brazil
ABSTRACT Stichelia pelotensis (Lepidoptera, Riodinidae) is an endemic and threatened butterfly from the Pampa biome in southern Brazil, and has not been recorded in its type locality in the last 56 years. Recently, a population was found in two sites from extreme south Brazil, Pelotas, Rio Grande do Sul state. These records are an important find given the co

5. The sea-level highstand correlated to marine isotope stage (MIS) 7 in the coastal plain of the state of Rio Grande do Sul, Brazil
A planície costeira do estado do Rio Grande do Sul, no sul do Brasil, inclui quatro sistemas deposicionais do tipo laguna-barreira formados por sucessivas transgressões marinhas do Quaternário, correlacionadas aos estágios isotópicos marinhos (MIS) 11, 9, 5 e 1, apesar da escassez de idades absolutas. Este estudo descreve um máximo transgressivo marinh

6. Palynomorphs in Holocene sediments from a paleolagoon in the coastal plain of extreme southern Brazil
This paper presents the results of a qualitative palynological analysis of a 140 cm-thick section of Holocene sediments from a paleolagoon, representing the last 2600 years, taken from an outcrop at Hermenegildo Beach (33º42'S; 53º18'W), located in the municipality of Santa Vitória do Palmar, in the state of Rio Grande do Sul, Brazil. Samples were treated

7. Diet of Lontra longicaudis (Olfers, 1818) (Carnivora: Mustelidae) in three limnic systems in Southern Rio Grande do Sul State, Brazil
The aim of the present work was to study the diet of Lontra longicaudis in three limnic systems (anthropogenic shallow lakes, pluvial channel and coastal stream) in Rio Grande do Sul State coastal plain, southern Brazil. Fishes were the most consumed item in all the three systems, being Mugilidae the most representative family in the pluvial channel and coas

8. Geomorfologia, estratigrafia de sequências e potencial de preservação dos sistemas Laguna Barreira do Quaternário Costeiro do Rio Grande do Sul.
The stratigraphic record of Rio Grande do Sul Coastal Plain embraces four high-frequency depositional sequences corresponding to four barrier-lagoon systems (I to IV). These sequences have been developed during the Pleistocene and Holocene, in response to glacioeustatic cycles of 100 ka. The Holocene coastal system, related to the younger sequence (IV), exhi

9. A hybrid zone of the genus Ctenomys: a case study in southern Brazil
We describe variation at microsatellite loci and the chromosomal polymorphisms of a hybrid population, and hybridizing populations of Ctenomys minutus (the minor tuco-tuco) from the coastal plain of Rio Grande do Sul, southern Brazil. Cytogenetic analysis and a survey of six microsatellite loci included 101 specimens of C. minutus from the parental populatio

11. Chlorococcales latu sensu(Chlorophyceae) em ambientes aquáticos na planície costeira do Rio Grande do Sul, Brasil : ecológicos taxonomia, distribuição e aspectos ecológicos / Desmodesmus and Scenedesmus (Scendesmaceae, Sphaeropleales, Chlorophyceae) in aquatic environments from the Coastal Plain of Rio Grande do Sul, Brazil
Este trabalho trata do estudo da flora de Desmodesmus An, Friedl & Hegew. e Scenedesmus Meyen, encontrada em lagoas isoladas, lagoas interligadas, banhados, açudes e ambientes lóticos da Planície Costeira do Rio Grande do Sul. A composição taxonômica, e as relações entre a riqueza e a densidade com as variáveis temperatura e pH foram avaliadas. O es

12. Morfodinâmica da embocadura da Lagoa do Peixe e da linha de praia adjacente
The investigation of morphological change in lagoonal inlets and shorelines can be instrumental to describe the influence of short term coastal processes. The Lagoa do Peixe (LP) is set within the Parque Nacional da Lagoa do Peixe (PNLP), 344 km², located on the mid-section of the Rio Grande do Sul coastal plain. The objective of this work was to describe t
