| ABSTRACT Tree legumes are an underexploited resource in warm-climate silvopastures. Perceived benefits of tree legumes include provisioning (browse/mast, timber, fuel, human food, natural medicines, and ornamentals), regulating (C sequestration, greenhouse gas mitigation, soil erosion control and riparian buffers, shade, windbreaks, and habitat for pollinators), supporting (biological N2-fixation, nutrient cycling, soil fertility and soil health, photosynthesis, and primary productivity), and cultural ecosystem services. Tree legumes, however, have not been assessed to the same extent as herbaceous legumes. Once tree legumes are established, they are often more persistent than most herbaceous legumes. There are limitations for extended research with tree... |

| Abstract We report the first known infestation of mangroves by the invasive moth Hyblaea puera in Paraná, Southern Brazil. The infestation caused massive defoliation of Avicennia schaueriana trees, affecting approximately 20,000 hectares of mangroves. We discuss the implications for conservation and management, focusing on protected areas, the ecology of mangroves, and local livelihoods. |

| Monetary contributions might not be appropriate welfare measures in contingent valuation (CV) when household incomes are very low. In such cases, willingness to pay (WTP) is restricted by a household's ability to reduce its consumption of other goods to pay for the environmental good under valuation. Beneficiaries, however, may be willing to contribute their time to work on a project instead of paying money. In this context, we assess the benefits of ecosystem services restoration in a rural area of high conservation value in central Chile, using a CV study that includes two WTP questions, one for cash and another for labor payments. The results indicate that labor payments in the form of a number of working hours per week were highly accepted among... |

| ABSTRACT: The extraction of sea salt depends on the occupation of large areas at the estuary banks, many of them inserted in Permanent Preservation Areas (PPAs). Thus, the objective was to evaluate the economic viability of Environmental Offsets (EO) as an alternative to the unoccupied PPAs in the saltworks. In order to do so, 27 solar saltworks installed in the region of the Brazilian White Coast were evaluated for the occupation of PPAs - measured using images from satellite, georeferenced, vectored with corresponding PPA bands generated - and estimated to EO (Impact Degree x Sum of the investments necessary to implement the project) and Economic Impact (Net Present Value, with long-term interest rate of 7%) of vacating PPAs. It was considered that EO... |
