In 30 surveys across Cordoba city and surroundings (Argentina) I recorded, from November 2001 to May 2002, a total of 109 ornamental plants infested with aphid colonies. Surveys were conducted in the local botanical garden as well as homestead gardens and nurseries. Seventeen species of aphids were identified, 4 of which are new species in the area, from 47 ornamental plants. In a total of 59 plant/aphid associations, 38 new associations were found. I present the first record of aphids colonizing Cactaceae in Argentina. Most aphid colonies were medium and a high proportion (more than 40%) showed alate individuals. The most frequent aphid species, Aphis gossypii Glover and Aphis craccivora Koch were especially associated with the most frequent damages:... |

Recent studies have intended to quantify urban consumption and trade in Amazonian towns. However, little is still known about the different ways in which bushmeat is made available in urban areas, including commercial and noncommercial flows, and how those flows contribute to link forests to urban livelihoods. In this study we qualitatively describe the structure and functioning of bushmeat flows in terms of species, catchment area, stakeholders involved, and the motivations for their activity in the main towns of the Amazon trifrontier region between Brazil, Colombia, and Peru. We show that bushmeat trade to urban areas exists under an organized but invisible commodity chain providing a source of income to about 195 persons. Bushmeat is made available... |

Nature-based solutions promoting green and blue urban areas have significant potential to decrease the vulnerability and enhance the resilience of cities in light of climatic change. They can thereby help to mitigate climate change-induced impacts and serve as proactive adaptation options for municipalities. We explore the various contexts in which nature-based solutions are relevant for climate mitigation and adaptation in urban areas, identify indicators for assessing the effectiveness of nature-based solutions and related knowledge gaps. In addition, we explore existing barriers and potential opportunities for increasing the scale and effectiveness of nature-based solution implementation. The results were derived from an inter- and transdisciplinary... |
