Lost in aggregation? On the importance of local food price data for food poverty estimates

American Journal of Agricultural Economics, EarlyView.
Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

Choice experiments on land managers' participation in environmental programs: A systematic review and meta‐analysis of estimate validity

American Journal of Agricultural Economics, EarlyView.
Abstract Discrete choice experiments are increasingly being used to estimate land managers' willingness to accept participation in incentive‐based environmental programs. This is a specific application of discrete choice experiments: the estimation of willingness to accept for a private good (program participation) where respondents have to make trade ...

Soil salinity effects on pollen and pollinator visitation in a buzz‐pollinated glycophyte, Solanum carolinense

American Journal of Botany, EarlyView.
Abstract Premise Human activity has significantly altered the salt cycle, affecting an estimated 2.5 billion acres of soil worldwide. Elevated soil salinity is a well‐known plant stressor, but it may also affect interactions between plants and insects, which are often sodium limited.

A case of budding speciation in the California Floristic Province and infraspecific divergence in Abronia villosa

American Journal of Botany, EarlyView.
Abstract Premise Budding speciation occurs when peripheral populations adapt to local ecological conditions and “bud” off from a widespread progenitor species. Traditionally regarded as rare because of its sympatric and parapatric nature, budding speciation is largely understudied.

Extroparvum occidentale gen. et sp. nov. and the Cretaceous diversification of Lauraceae

American Journal of Botany, EarlyView.
Abstract Premise The fossil record of Lauraceae extends back to the Early Cretaceous and comprises numerous flowers. However, phylogenetic relationships of many of these fossil flowers remain unresolved. To better understand the early evolutionary history of Lauraceae, we conducted phylogenetic analyses of living and extinct members of the family and ...
