Nature-Based Solutions for Agriculture in Circular Cities: Challenges, Gaps, and Opportunities
(Peer reviewed; Journal article, 2021-09-17)Urban agriculture (UA) plays a key role in the circular metabolism of cities, as it can use water resources, nutrients, and other materials recovered from streams that currently leave the city as solid waste or as wastewater ... -
Neighbourhood convenience stores and childhood weight outcomes: an instrumental variable approach
(Journal article; Peer reviewed, 2018-07-21)The association between the commercial food environment and childhood obesity is increasingly assessed in the literature, but little is known about the role of convenience stores, an important food retail format worldwide. ... -
Nematodes as a Limiting Factor in Potato Production in Scandinavia
(Journal article; Peer reviewed, 2012-03-22)Plant parasitic nematodes associated with potato feed on roots and/or tubers. About 70 species, representing 24 genera, have been reported from potato. Since nematodes attack underground plant parts, there are no reliable ... -
The Neonicotinoid Imidacloprid Impairs Learning, Locomotor Activity Levels, and Sucrose Solution Consumption in Bumblebees (Bombus terrestris)
(Peer reviewed; Journal article, 2023-03-20)Bumblebees carry out the complex task of foraging to provide for their colonies. They also conduct pollination, an ecosystem service of high importance to both wild plants and entomophilous crops. Insecticides can alter ... -
Neutral processes related to regional bee commonness and dispersal distances are important predictors of plant–pollinator networks along gradients of climate and landscape conditions
(Peer reviewed; Journal article, 2022-10-17)Understanding how niche-based and neutral processes contribute to the spatial varia-tion in plant–pollinator interactions is central to designing effective pollination con-servation schemes. Such schemes are needed to ... -
