New Zealand Journal of Agricultural Research, Volume 66, Issue 6, Page 519-619, December 2023., 2023 ABSTRACT Food and feed has been produced from genetically modified (GM) crops for 25 years. It is timely to review whether this technology has globally delivered the expected benefits and whether the ongoing debate on risks is justified. Expected benefits associated with GM include increased crop yields, reduced pesticide and insecticide use, reduced ...

Grazing hay meadows: History, distribution, and ecological context
Applied Vegetation Science, Volume 26, Issue 2, April/June 2023., 2023 Grazing hay meadows, once widespread across Europe, became limited to rural regions with maintained traditional agriculture. Spring and autumn grazing, along with corralling and manuring of hay meadows, were integral parts of all farming systems existing in the Carpathian Mountains in parallel before agricultural intensification. We describe details on

Drying conditions alter the defensive function of seed mucilage against granivores
Journal of Ecology, Volume 111, Issue 2, Page 525-536, February 2023., 2023 We found that increasing temperatures reduced the drying time of mucilaginous seeds, leading to less strong attachment and easier exploitation by granivorous ants. These results add to a small, but growing, literature on the importance of seed mucilage in seed survival and demonstrate strong and largely predictable context‐dependency in this trait's ...

Risk assessment for Birds and Mammals
EFSA Journal, Volume 21, Issue 2, February 2023., 2023 Abstract The European Commission asked EFSA to revise the Guidance on the risk assessment for birds and mammals. That guidance described how to perform risk assessment for birds and mammals from plant protection products, containing pesticide active substances, in accordance with Regulation (EU) 1107/2009.

Ecology and Evolution, Volume 12, Issue 10, October 2022., 2022 Intra‐annual growing season precipitation variability and temperature variability indirectly influenced the community intra‐annual biomass stability by negative effect on intra‐annual species asynchrony and intra‐annual species richness, respectively. ; Intra‐annual biomass stability of dominant species and dominant functional group were insensitive to

Controlled freezing studies as a corollary selection method for winterhardiness in perennial flax
Crop Science, Volume 62, Issue 5, Page 1734-1757, September/October 2022., 2022 Abstract Perennial flax (Linum spp.) breeding objectives at the University of Minnesota (UMN) are to develop agronomic (oilseed, fiber) and horticultural (cut flower, garden perennial) varieties that are hardy in Minnesota (USDA Plant Hardiness Zones 3 and 4).

Can omic tools help generate alternative newer sources of edible seed oil?
Plant Direct, Volume 6, Issue 6, June 2022., 2022 Abstract There are three pathways for triacylglycerol (TAG) biosynthesis: De novo TAG biosynthesis, phosphatidylcholine‐derived biosynthesis, and cytosolic TAG biosynthesis. Variability in fatty acid composition is mainly associated with phosphatidylcholine‐derived TAG pathway. Mobilization of TAG‐formed through cytosolic pathway into lipid droplets is

Using δ15N to screen for nitrogen fixation: Reference plant position and species
Agronomy Journal, Volume 114, Issue 3, Page 1842-1850, May/June 2022., 2022 Abstract The δ15N natural abundance technique is frequently used to quantify the proportion of legume nitrogen derived from atmospheric fixation (%Ndfa). This method compares the δ15N of a legume with a nonlegume reference plant to estimate the %Ndfa. For accurate estimations, it is recommended to pair each legume plot with a nonlegume reference plant ...

Ecology and Evolution, Volume 11, Issue 18, Page 12816-12833, September 2021., 2021 In our study, we analyzed the impact of restoration on the genetic variation of typical grassland plant species. Our results indicate that the transfer of local seed‐containing plant material is a technique highly suitable to create genetically variable and locally adapted plant populations.

Journal of Ecology, Volume 109, Issue 5, Page 2219-2233, May 2021., 2021 In a study of 43 plant species, the most consistent response to density was an increase in the proportion of biomass allocated to roots, suggesting that intraspecific competition was mainly for below‐ground resources. Our results further show that growth conditions, species characteristics and their interactions influence patterns of biomass allocation
