Ecosystem service trade-offs and land use among smallholder farmers in eastern Paraguay Ecology and Society
Grossman, Jake J.; University of Minnesota: Twin Cities, Department of Ecology, Evolution, and Behavior; gross679@umn.edu.
The trade-off between economically critical provisioning services and environmentally sustaining supporting services often seems absolute. Yet, when land use is inefficient, managers may be able to increase provision of both economically and ecologically sustaining services. To explore such sustainable "win-win" outcomes, I present a model of predicted trade-offs of provisioning and supporting services on smallholder farms in eastern Paraguay. The spatially implicit model simulates smallholder parcels as mosaics of subsistence agriculture, cattle pasture, eucalyptus plantations, and/or natural forest cover, and predicts provisioning and supporting service supply depending on the relative abundance of each land-use type per parcel. I represent provisioning...

New records of Neusticomys oyapocki (Rodentia, Sigmodontinae) from a human-dominated forest landscape in northeastern Brazilian Amazonia Mastozool. neotrop.
Leite,Rafael do Nascimento; da Silva,Maria Nazareth F.; Gardner,Toby A..
Here we report three new specimens of Neusticomys oypocki from northeastern Brazilian Amazonia collected in a plantation forestry landscape. These represent one third of all known N. oyapocki specimens and extend the distribution of the species ca. 360 km southwards. All specimens were captured with pitfall traps, which reinforce the importance of this method for comprehensive small mammal inventories. Moreover, captures occurred during the dry season in primary, secondary, or plantation forests, suggesting that species of Neusticomys may be more opportunistic habitat generalists than previously thought.
