| The term "commons" refers to collectively exploited resources and their systems of usage; a synonymous term is common pool resources. Fisheries are typical common pool resources and also one of the most conspicuous examples of unsustainable use of natural resources. We examine one of the few globally important fisheries that is held to be sustainable, the Peruvian anchovy fishery, and considers the extent to which the institutional characteristics of the fishery conform to design principles that are considered prerequisites for long-term, successful, community-based common pool resources. Results showed that greater conformity to the principles was found in the sustainable phase of the fishery, compared to its unsustainable phase. For this case study, the... |

| Although bigleaf mahogany [Swietenia macrophylla King (Meliaceae)] is the premier timber species of Latin America, its exploitation is unsustainable because of a pattern of local depletion and shifting supply. We surveyed experts on the status of mahogany in Bolivia and Peru, the world's past and present largest exporters. Bolivia no longer has commercially viable mahogany (trees > 60 cm diameter at breast height) across 79% of its range. In Peru, mahogany's range has shrunk by 50%, and, within a decade, a further 28% will be logged out. Approximately 15% of the mahogany range in these two countries is protected, but low densities and illegal logging mean that this overestimates the extent of mahogany under protection. The international community... |

| Reduced Emissions from Deforestation and Forest Degradation (REDD+) has received strong support as a major component of future global climate change policy. The financial mechanism of REDD+ is payment for the ecosystem service of carbon sequestration in tropical forests that is expected to create incentives for conservation of forest cover and condition. However, the costs of achieving emissions reduction by these means remain largely unknown. We assess the set-up, implementation, and monitoring costs, i.e., collectively the transaction costs, of six of the first seven REDD+ project designs from the Peruvian Amazon and compare them with established projects in Brazil and Bolivia. The estimated costs vary greatly among the assessed projects from US$0.16 to... |

| Complex systems are shaped by cross-scale interactions, nonlinear feedbacks, and uncertainty, among other factors. Transdisciplinary approaches that combine participatory and conventional methods and democratize knowledge to enable diverse inputs, including those from local, informal experts, are essential tools in understanding such systems. The metaphor of a “bridge” to overcome the divide between different disciplines and knowledge systems is often used to advocate for more inclusive approaches. However, there is a shortage of information and consensus on the process, methodologies, and techniques that are appropriate to achieve this. This paper compares two case studies from Peru and South Africa in which community-level assessments... |

| Recent high-resolution hydrographic measurements (1976-2001) from the eastern South Pacific (ESP) were employed combined with high-resolution data from the World Ocean Circulation Experiment to evaluate the vertical and horizontal extension of the OMZ (oxygen minimum zone, < 20 µmol kg-1) there. Of the six permanent hypoxic regions in the world oceans, the ESP OMZ is volumetrically the fourth largest, occupying 2.74 x 10(6) km³ and accounting for ~11% globally. Examples of variability in the vertical position of the OMZ in the water-column and also in its intensity offshore central Chile will be addressed. We conclude that the OMZ in the ESP is partly based on old, low-oxygen waters from intermediate depths of the North Pacific Ocean, which were further... |

| The oxygen minimum zone (OMZ) off the Peruvian coast, though shallower and more intense than other OMZs, exhibits a spatial distribution that varies with latitude, depth and distance to the coast. The spatial variability in oxygen content imposes latitudinal and bathymetric zonations of the benthic communities. Nevertheless the spatial patterns of the benthic communities are also modulated by the bottom topography and the sedimentary environments, which in turn are controlled to a large extent by the poleward undercurrent. While the bathymetric patterns of the macro- and meiobenthos have been previously described, latitudinal changes have received less attention. We found that, in parallel with opposed latitudinal gradients of oxygen and fresh organic... |

| In fluctuating environments, matching breeding timing to periods of high resource availability is crucial for the fitness of many vertebrate species, and may have major consequences on population health. Yet, our understanding of the proximate environmental cues driving seasonal breeding is limited. This is particularly the case in marine ecosystems, where key environmental factors and prey abundance and availability are seldom quantified. The Northern Humboldt Current System (NHCS) is a highly productive, low-latitude ecosystem of moderate seasonality. In this ecosystem, three tropical seabird species (the Guanay Cormorant Phalacrocorax bougainvillii, the Peruvian Booby Sula variegata, and the Peruvian Pelican Pelecanus thagus) live in sympatry and prey... |

| Since flat subduction of the Nazca Plate beneath Peru was first recognized in the 1970s and 1980s a satisfactory explanation has eluded researchers. We present evidence that a lost oceanic plateau (Inca Plateau) has subducted beneath northern Peru and propose that the combined buoyancy of Inca Plateau and Nazca Ridge in southern Peru supports a 1500 km long segment of the downgoing slab and shuts off arc volcanism. This conclusion is based on an analysis of the seismicity of the subducting Nazca Plate, the structure and geochemistry of the Marquesas Plateau as well as tectonic reconstructions of the Pacific¿Farallon spreading center 34 to 43 Ma. These restore three sub¿parallel Pacific oceanic plateaus; the Austral, Tuamotu and Marquesas, to two Farallon... |

| Species in the Order Carnivora are susceptible to habitat fragmentation, deforestation, and climate change because of their medium to large size, large spatial requirements, and other species-specific requirements, providing challenges to conservation and management. Understanding their distributions and occurrence in the face of these threats is crucial for conservation. Peru has 21 carnivore species regulated by the CITES Convention (61.8% of all Peruvian carnivore species). The aims of this project were: a) to generate distribution maps of Peruvian carnivores listed by CITES, b) to describe their distribution by ecoregions, c) to describe changes in species richness through time, and d) to identify species and areas in need of further research and... |
