Animal-vehicle collisions are the main negative impact of roads on wildlife, where they cause population declines, shifts in community structure, and potential changes in species behavior. Here, we determined mammal roadkill rates and the hotspots with higher rates for medium-and large-bodied mammals on the Highway PR-445 in the state of Paraná, Br...
Ao longo da história, a relação do homem com a natureza foi consolidada a partir de uma visão utilitarista dos recursos naturais. Foi justamente a partir da década de 70, quando a população mundial beirava os 4 bilhões de habitantes, que os primeiros eventos voltados
para discutir os limites de nosso crescimento foram realizados. Desde então, a Ed...

The Pampa represents one of the domains of highest floristic richness in South America, however, especially in relation to the ferns and lycophytes, it still poorly known. This study aims to list the ferns and lycophytes associated with the Tigre and Palomas hills and discuss the floristic aspects that shape the fern and lycophyte flora at the isol...
The galls are structures formed of plant tissues in response to the activity of different types of organisms, especially by insects. As a consequence of an intimate relationship with their host plants, most of these insects have a very narrow host range. In this study we report for the first time the occurrence of galls on Microgramma mortoniana (P...

Sarcophagida...
Most studies on holoparasitic plants have focused on taxonomic or systematic issues. The objective of this study was to examine the ecological aspects of parasitism of Langsdorffia hypogaea (Balanophoraceae) in the Pantanal wetlands. Individuals of L. hypogaea were dug out by hand and the host trees were identified. Eighty-eight percent of host tre...

Most of the information available about the reproduction of Panthera onca comes from animals in captivity or sightings by hunters and little is known about the reproductive behavior of this species in the gild. In this paper, we describe the courtship behavior observed between a pair of jaguars (Panthera onca) on the banks of the Rio Vermelho, in t...
A vistar um animal silvestre atropelado é um cenário comum a quem trafega por muitas rodovias brasileiras. No entan-to, o atropelamento de animais silvestres é uma das prin-cipais ameaças a muitas espécies da fauna brasileira. O núme-ro de animais mortos todos os anos em nossas rodovias ultra-passa os milhares e, até então, nada se tem feito para m...
