Interspecific competition underlying mutualistic networks

open access: yes, 2012
The architecture of bipartite networks linking two classes of constituents is affected by the interactions within each class. For the bipartite networks representing the mutualistic relationship between pollinating animals and plants, it has been known ...

Nudging local: Do information treatments work?

open access: yesJournal of the Agricultural and Applied Economics Association, EarlyView.
Abstract This study examines how information nudges shape consumer preferences for locally grown foods. Using an online discrete choice experiment with blueberries, we assess the effectiveness of tailored information emphasizing local economy support, quality, and environmental benefits in increasing consumer valuation of state‐branded products ...

Native bees (Hymenoptera: Apoidea) and berry polycultures: Studying farmers’ motivations for diversification and the impact of mass floral resources on pollinator communities [PDF]

open access: yes, 2017
Floral resource continuity is an important component in pollinator conservation. Mass blooms early in the season may bolster pollinator communities on sequentially flowering crops by creating a resource pulse in an agricultural landscape.

Perinatal Exposure to the Neonicotinoid Thiacloprid Impacts Transcription of Neuroplasticity and Neuroendocrine Markers in Mice but Not in the Zebrafish Model

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Neonicotinoids are widely used insecticides in agriculture, aquaculture, pet care, and urban pest control. Initially developed to selectively target the insect cholinergic system, their extensive use has raised concerns about adverse effects on nontarget vertebrates.

Resource availability and competition shape pollinator trophic specialization in longleaf pine savannas

open access: yesBasic and Applied Ecology
Realized trophic specialization, or the food resources with which a species interacts locally, is driven by a species fundamental niche, resource availability, and competition. However, the simultaneous effects of resource availability and competition on
