Ethnoecology of pollination and pollinators

open access: yesRevue d'ethnoécologie, 2015
This paper brings together three case studies on the interrelationships amongst people, pollination processes and pollinators (notably honeybees). In the palm groves of Saharan oases, the milieu and varieties of palm trees are created by horticulturalists, who fulfil themselves the role of pollinators.

Climate change and perennial crop production: Evidence of yield impact and adaptation in California

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Perennial crops are economically important. They contribute to food security, providing essential nutrients that are often lacking in annual crops, and provide additional environmental benefits compared with annual crops. Despite their importance, empirical research on the impacts of climate change and adaptation on perennial crops remains ...

Evaluating the African arid corridor hypothesis: A meta‐analysis including the phylogenetic and biogeographical history of Sesamothamnus

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise We examined the African arid corridor (AAC) disjunction pattern of vascular plants between northeastern and southwestern Africa in the context of geological and climatic events since the late Miocene. We developed a phylogenetic and biogeographical framework for the arid‐adapted genus Sesamothamnus (Pedaliaceae), a classic example of ...

Ecological niche modeling reveals habitat differentiation and climatic vulnerability in two imperiled, sympatric southern Appalachian carnivorous plants

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Understanding the habitat requirements of imperiled flora is critical for informing ex situ conservation practices, designing effective reintroduction strategies, and understanding how climate change will impact such species, especially in montane regions with high levels of environmental heterogeneity. In southern Appalachia, USA, the

Pollinator conservation—the difference between managing for pollination services and preserving pollinator diversity

open access: yesCurrent Opinion in Insect Science, 2015
Our review looks at pollinator conservation and highlights the differences in approach between managing for pollination services and preserving pollinator diversity. We argue that ecosystem service management does not equal biodiversity conservation, and that maintaining species diversity is crucial in providing ecosystem resilience in the face of ...
