Delivering Integrated Pest and Pollinator Management (IPPM).

Trends Plant Sci 2020 Jun 12;25(6):577-589. Epub 2020 Mar 12.

Department of Plant Protection Biology, Swedish University of Agricultural Sciences, PO Box 102, SE-23053 Alnarp, Sweden.

The need to reduce pollinator exposure to harmful pesticides has led to calls to expedite the adoption of integrated pest management (IPM). We make the case that IPM is not explicitly 'pollinator friendly', but rather must be adapted to reduce impacts on pollinators and to facilitate synergies between crop pollination and pest control practices and ecosystem services. To reconcile these diverse needs, we introduce a systematic framework for 'integrated pest and pollinator management' (IPPM). Read More

Crop and forest pest metawebs shift towards increased linkage and suitability overlap under climate change.

Commun Biol 2020 May 11;3(1):233. Epub 2020 May 11.

ETH, Landscape Ecology, Zurich, Switzerland.

Global changes pose both risks and opportunities to agriculture and forestry, and biological forecasts can inform future management strategies. Here, we investigate potential land-use opportunities arising from climate change for these sectors in Europe, and risks associated with the introduction and establishment of novel insect pests. Adopting a metaweb approach including all interaction links between 126 crops and forest tree species and 89 black-listed insect pest species, we show that the metawebs shift toward increased numbers of links and overlap of suitable area under climate change.

Why Seed Physiology Is Important for Genebanking.

Plants (Basel) 2020 May 2;9(5). Epub 2020 May 2.

Global Crop Diversity Trust, Platz Der Vereinten Nationen 7, 53113 Bonn, Germany.

Genebank management is a field in its own right; it is multifaceted, requiring a diverse set of skills and knowledge. Seed physiology is one area that is critical to the successful operation of seed genebanks, requiring understanding of seed quality during development and maturation, seed dormancy and germination, and seed longevity in storage of the target species. Careful management of the workflow between these activities, as seeds move from harvest to storage, and the recording and management of all relevant associated data, is key to ensuring the effective conservation of plant genetic resources.

A critical analysis of the potential for EU Common Agricultural Policy measures to support wild pollinators on farmland.

J Appl Ecol 2020 Apr 16;57(4):681-694. Epub 2020 Feb 16.

Plant Ecology and Nature Conservation Group Wageningen University Wageningen The Netherlands.

Agricultural intensification and associated loss of high-quality habitats are key drivers of insect pollinator declines. With the aim of decreasing the environmental impact of agriculture, the 2014 EU Common Agricultural Policy (CAP) defined a set of habitat and landscape features (Ecological Focus Areas: EFAs) farmers could select from as a requirement to receive basic farm payments. To inform the post-2020 CAP, we performed a European-scale evaluation to determine how different EFA options vary in their potential to support insect pollinators under standard and pollinator-friendly management, as well as the extent of farmer uptake.

Plants with lengthened phenophases increase their dominance under warming in an alpine plant community.

Sci Total Environ 2020 Apr 24;728:138891. Epub 2020 Apr 24.

Department of Agroecology, Aarhus University, Tjele 8830, Denmark; Center for Circular Bioeconomy, Aarhus University, Tjele 8830, Denmark. Electronic address:

Predicting how shifts in plant phenology affect species dominance remains challenging, because plant phenology and species dominance have been largely investigated independently. Moreover, most phenological research has primarily focused on phenological firsts (leaf-out and first flower dates), leading to a lack of representation of phenological lasts (leaf senescence and last flower) and full phenological periods (growing season length and flower duration). Here, we simultaneously investigated the effects of experimental warming on different phenological events of various species and species dominance in an alpine meadow on the Tibetan Plateau.

Neonicotinoids suppress contact chemoreception in a common farmland spider.

Sci Rep 2020 Apr 27;10(1):7019. Epub 2020 Apr 27.

Crop Research Institute, Biodiversity Lab, Prague, Czech Republic.

Neonicotinoid insecticides are increasingly recognized for their role as information disruptors by modifying the chemical communication system of insects and therefore decreasing the chances of reproduction in target insects. However, data from spiders are lacking. In the present study, we tested the responses of males of a common agrobiont spider, Pardosa agrestis, to the application of field-realistic concentration of acetamiprid, which was formulated as Mospilan, and trace amounts of thiacloprid, which was formulated as Biscaya.

Can flooding-induced greenhouse gas emissions be mitigated by trait-based plant species choice?

Sci Total Environ 2020 Apr 10;727:138476. Epub 2020 Apr 10.

Soil Biology Group, Wageningen University & Research, PO Box 47, 6700 AA Wageningen, the Netherlands; Department of Agroecology - Soil Fertility, Aarhus University, Blichers Allé 20, 8830 Tjele, Denmark.

Intensively managed grasslands are large sources of the potent greenhouse gas nitrous oxide (NO) and important regulators of methane (CH) consumption and production. The predicted increase in flooding frequency and severity due to climate change could increase NO emissions and shift grasslands from a net CH sink to a source. Therefore, effective management strategies are critical for mitigating greenhouse gas emissions from flood-prone grasslands. Read More

Cadmium and Mercury phytostabilization from soil using Miscanthus × giganteus.

Sci Rep 2020 Apr 21;10(1):6685. Epub 2020 Apr 21.

Institute for Medical Research and Occupational Health, Ksaverska c. 2, 10000, Zagreb, Croatia.

The determination of the effects of cadmium and mercury on the growth, biomass productivity and phytoremediation potential of Miscanthus × giganteus (MxG) grown on contaminated soil was the main aim of this paper. The use of bioenergy plants as an innovative strategy in phytotechnology gives additional benefits, including mitigation and adaptation to climate change, and soil remediation without affecting soil fertility. An experiment was set up as a randomized complete block design with the treatments varied in concentrations of Cd (0, 10 and 100 mg kg soil) and Hg (0, 2 and 20 mg kg soil) added to the soil.

Pseudomonas fluorescens promote photosynthesis, carbon fixation and cadmium phytoremediation of hyperaccumulator Sedum alfredii.

Sci Total Environ 2020 Jul 8;726:138554. Epub 2020 Apr 8.

MOE Key Laboratory of Environment Remediation and Ecological Health, College of Environmental and Resource Sciences, Zhejiang University, Hangzhou 310058, China. Electronic address:

Plant growth-promoting bacteria (PGPB) can promote photosynthesis and biomass production of hyperaccumulators, achieving enhanced phytoremediation efficiency of cadmium (Cd). A better understanding of the mechanisms controlling photosynthesis of hyperaccumulating plants by PGPB is necessary for developing strategies that promote the practical phytoextraction of Cd-polluted soils. In this study, chlorophyll fluorescence, gas exchange, and transcriptome sequencing were conducted to evaluate the physiological and transcriptional changes on photosynthesis and carbon fixation in hyperaccumulator Sedum alfredii after inoculation with PGPB Pseudomonas fluorescens.

Effects of winter chilling vs. spring forcing on the spring phenology of trees in a cold region and a warmer reference region.

Sci Total Environ 2020 Jul 31;725:138323. Epub 2020 Mar 31.

Swiss Federal Institute for Forest, Snow and Landscape Research WSL, CH-8903 Birmensdorf, Switzerland; Key Laboratory of Geographical Processes and Ecological Security in Changbai Mountains, Ministry of Education, School of Geographical Sciences, Northeast Normal University, Changchun 130024, China.

Regions at high latitudes and high altitudes are undergoing a more pronounced winter warming than spring warming, and such asymmetric warming will affect chilling and forcing processes and thus the spring phenology of plants. We analyzed winter chilling and spring forcing accumulation in relation to the spring phenology of three tree species (Ulmus pumila, Populus simonii, and Syringa oblata) growing in a cold region (CR) compared with trees in a warmer reference region (WR), using the Dynamic Model and the Growing Degree Hour (GDH) model. We tested that forcing rather than chilling affects the spring phenology of trees in CR (hypothesis I), and that trees in CR have both lower mean chilling and forcing temperature and thus longer accumulation periods than trees in WR (hypothesis II).

Arbuscular mycorrhiza influences carbon-use efficiency and grain yield of wheat grown under pre- and post-anthesis salinity stress.

Plant Biol (Stuttg) 2020 Apr 16. Epub 2020 Apr 16.

Department of Agroecology, Aarhus University, Research Centre Flakkebjerg, DK-4200, Slagelse, Denmark.

Soil salinity severely affects and constrains crop production worldwide. Salinity causes osmotic and ionic stress, inhibiting gas exchange and photosynthesis, ultimately impairing plant growth and development. Arbuscular mycorrhiza (AM) have been shown to maintain light- and carbon use-efficiency under stress, possibly providing a tool to improve salinity tolerance of the host plants. Read More

Modelling the monthly abundance of Culicoides biting midges in nine European countries using Random Forests machine learning.

Parasit Vectors 2020 Apr 15;13(1):194. Epub 2020 Apr 15.

Division for Diagnostics and Scientific Advice, National Veterinary Institute, Technical University of Denmark (DTU), Lyngby, Denmark.

Background: Culicoides biting midges transmit viruses resulting in disease in ruminants and equids such as bluetongue, Schmallenberg disease and African horse sickness. In the past decades, these diseases have led to important economic losses for farmers in Europe. Vector abundance is a key factor in determining the risk of vector-borne disease spread and it is, therefore, important to predict the abundance of Culicoides species involved in the transmission of these pathogens.

Negative Roles of Strigolactone-Related SMXL6, 7 and 8 Proteins in Drought Resistance in .

Biomolecules 2020 Apr 14;10(4). Epub 2020 Apr 14.

Stress Adaptation Research Unit, RIKEN Center for Sustainable Resource Science, 1-7-22, Suehiro-cho, Tsurumi, Yokohama 230-0045, Japan.

Previous investigations have shown that the SUPPRESSORS OF MAX2 1-LIKE6, 7 and 8 (SMXL6, 7 and 8) proteins redundantly repress strigolactone (SL) signaling in plant growth and development. Recently, a growing body of evidence indicated that SLs positively regulate plant drought resistance through functional analyses of genes involved in SL biosynthesis and positive regulation of SL signaling. However, the functions of the SL-signaling negative regulators SMXL6, 7 and 8 in drought resistance and the associated mechanisms remain elusive. Read More
