Insects are important environmental bioindicators, due to the species diversity and wide range of habitats occupied. The present study evaluated the temporal variation in composition and abundance of soil insects in an urban forest fragment in the municipality of Toledo, in the state of Paraná, by analyzing their abundance and seasonality. Monthly samplings were conducted between August 2011 and July 2012 at four sampling sites within the fragment. At each site, three pitfall traps remained exposed for 48 hours. Captured insects were fixed in alcohol, sorted and identified. Throughout the study period, we captured 11,568 insects from 11 orders and 35 families. Coleoptera was the richest order (12 families), followed by Diptera and Hemiptera (5),... |

The richness and abundance of the assemblage of species in a community are a way to understand the patterns of diversity found around the world. This study describes the assemblages of Saturniidae and Sphingidae in an area of Montana Mixed Ombrophilous Forest, Tijucas do Sul, Paraná, Brazil, 880m, 25º50'8.93"S, 49º 02'55.20"W. Samples were collected between November 2010 and September 2011 during two nights at the twelve new moons periods with a light trap equipped with black light lamp (ultraviolet) of 46 watts between two mercury mixed-light lamps HWL 250 watts from 6:00 p.m to 06:00 a.m. The sampling effort totaled 288 hours. This sampling effort was responsible for the capture of 1235 specimens, distributed in 124 species: 858 specimens and 86 species... |

Insects associated with sweet potato, Ipomoea batatas were surveyed at Ituporanga Experimental Station, EPAGRI S.A., Santa Catarina State, Brazil, from 1991 to 1994. Astylus variegatus Germ. (Coleoptera: Dasytidae) and Chaetocnema apricaria Suffr. (Coleoptera: Chrysomelidae) were abundant throughout the crop cycle. The complex of Homoptera (Aphididae: Pemphigida e and Cicadellidae), Diabrotica speciosa Germ., and Typophorus nigritus versutus Lef. (Coleoptera: Chrysomelidae) were constantly present but at lower levels than A. variegatus and C. apricaria. Systena sp. (Coleoptera: Chrysomeliadae) and Lagria villosa Fabr. (Coleoptera: Lagriidae), were casual and occurred at low frequency. |

Abstract: Habitat fragmentation is one of the principal causes of the decline of species worldwide, and the Brazilian Atlantic Forest and Cerrado savanna biomes are among the most severely affected by this process. While highly fragmented, remnants of Atlantic Forest can still be found within the Cerrado domain of southern Goiás, where previous studies have revealed high levels of biodiversity. To inventory the mammalian species that occur in the region, two fragments of semideciduous Atlantic Forest were sampled between 2011 and 2016, using line transect surveys and camera trapping. A total of 1016 records were obtained of 30 mammal species, of which eleven are under some threat of extinction. The species richness recorded on this study was similar to or... |

We present data on species composition, relative abundance and estimated densities for leaf-litter anuran amphibians from an Atlantic Forest area within the Parque Estadual do Desengano, in the state of Rio de Janeiro, Brazil, based on results of a short-term survey carried out during the winter at altitudes of 1000-1500 m. Three sampling methods were used: plot sampling, visual encounter surveys (VES; performed during the day, at the twilight, and at night), and pitfall traps. We recorded 13 species, with the direct-developer Ischnocnema parva (Girard, 1853) being the most abundant. Most frogs (ca. 90% of all individuals) sampled by VES were captured during the crepuscular and nocturnal periods. The estimated density of the local leaf-litter frog... |

Our objectives were to develop a method that would be appropriate for long-term ecological studies, but that would permit rapid surveys to evaluate biotic complementarity and land-use planning in Amazonia. The Amazon basin covers about 7 million km². Therefore, even a sparse coverage, with one sample site per 10.000 km², would require about 700 sampling sites. Financial considerations limit the number of sites and investment at each site, but incomplete coverage makes evaluation of biotic complementarity difficult or impossible (Reddy & Dávalos 2003). Our next challenge is to install similar systems throughout Amazonia. The cost, based on modification of Al Gentry's original design is moderate (less than US$ 50.000 per site if it is not necessary... |

Abstract: In order to inventory the species richness and fish fauna composition along the Ivinhema river basin, 232 stretches of rivers and streams were sampled from 2000 to 2018, using a rectangular sieve, trawls, gillnets, cast nets, and electrofishing. A total of 141 species was caught in the basin, including seven orders and 35 families. For the recorded species, 42 are from the upper Paraná river, 51 from lower Paraná river, 27 from other basins, two from other continents, and the origin for 19 species are unknown/not reported. Six species are registred for the first time in the upper Paraná river basin: Astyanax abramis, Moenkhausia oligolepis, Serrapinnus kriegi, Curimatopsis myersi, Pyxiloricaria menezesi, and Cichlasoma dimerus. This is the first... |

Infection caused by Toxoplasma gondii, toxoplasmosis, is one of the most frequent zoonoses in the world; it normally affects both genders equally. Humans are one of several possible intermediate hosts, and the disease is oligosymptomatic in most cases. Vertical transmission is an important cause of fetal malformation and sequels in newborns. Approximately 10% of postnatal cases present multiple manifestations, ranging from low fever and mild lymphadenopathy to severe encephalitis. In moderate cases, lesions such as retinochoroiditis may emerge during acute infection or even years later. We analyzed 313 cases of toxoplasmosis from 1992 to 2004, including 261 acute cases. Most patients were women (68.1%), and 39% of these were pregnant. Among acute infection... |

Abstract This study aimed to carry out a diagnosis of the cheese whey exploitation by the Brazilian dairy industry using a questionnaire survey. The dairy industries (n=100) were mainly from Southeast (55%) and South (25%) regions and supervised by the Federal Inspection System (80%). Most of them produced (67%) and processed (60%) sweet cheese whey, using it in whey dairy beverages (60%), Ricotta (20%), whey concentrate (15%), and milk blends (5%), which were resold for supermarkets (53%) or industries (20%). However, 27% of the industries discard whey in the effluent treatment system or use as animal feed, suggesting a market for using this by-product. |

Las gallinas ciegas se encuentran entre las plagas de suelo de mayor importancia económica en el mundo, incluyendo México. Considerando que el suelo es el ambiente más favorable para los nematodos entomopatógenos (NEP), es posible recuperar aislamientos de NEP que puedan tener el potencial para ser desarrollados como agentes de control biológico de esta plaga. Por esta razón se llevó a cabo un muestreo en el estado de Guanajuato, una de las regiones agrícolas más importantes de México. La colecta de nematodos se realizó utilizando larvas de Galleria mellonella como cebo en lugares con grandes poblaciones de gallina ciega. Los nematodos obtenidos se identificaron utilizando métodos morfológicos y moleculares. Después, la susceptibilidad de la gallina ciega... |

Both in literature and in practice, it is claimed that joint knowledge production (JKP) by researchers, policy makers, and other societal actors is necessary to make science relevant for addressing climate adaptation. Although recent assessments of JKP projects have provided some arguments in favor of their societal merit, much less is known about their scientific merit. We explored the latter by developing a conceptual framework addressing characteristics of doing JKP as well as hypotheses on potential merits and pitfalls in terms of its process, output, and impact for science. Semistructured interviews with six environmental science research leaders as well as discussions with five researchers involved in past JKP projects were used to start... |

Robert Costanza presents four compelling visions of the future, but the language he uses to describe them is emotive and value-laden and may bias the survey results. The descriptions and analogies used may evoke responses from the survey participants that reveal more about their reactions to the description than their attitudes toward a given scenario. It is hypothesized that the use of more neutral language may lead to more support for the scenario involving "self-limited consumption with ample resources" that Costanza calls "Big Government." If this hypothesis is correct, then the skeptic's policy that Costanza appears to prefer has the additional advantage of always leading to the favored outcome, regardless of the state of the world. |

An interdisciplinary field trip to a remote marine lab joined graduate students from fine arts and natural resource science departments to think creatively about the topic of climate change and science communication. We followed a learning cycle framework to allow the students to explore marine ecosystems and participate in scientific lectures, group discussions, and an artist-led project making abstract collages representing climate change processes. Students subsequently worked in small groups to develop environmental communication material for public visitors. We assessed the learning activity and the communication product using pre- and post-field trip participant surveys, focus group discussions, and critiques by art and communication experts of the... |

Small rural Alaskan communities face many challenges surrounding rapid social and ecological change. The role of local subsistence resources may change over time because of changes in social perception, economic need, and cultural patterns of use. We look at the Bering Sea’s Pribilof Islands, comprising two very small communities, and investigate the relationship between the local residents and seabirds as a natural resource. Seabirds may strengthen ties to older ways of life and have potential for future economic opportunities, or modernization may direct interest away from seabirds as a cultural and economic resource. We conducted a survey and interviews of residents of the two Pribilof Island communities, St. Paul and St. George, to assess... |
