daily calorific intake for countries across the globe. Wheat crops are attacked by a diverse range of herbivorous invertebrates (pests) that cause significant yield loss. It is anticipated that yield loss caused by pests will increase in response to a changing climate. Currently, these pests are primarily controlled using pesticides, however there is an increased need for more sustainable pest [...]

Smart Solutions, Big Returns: Closing Biodiversity Knowledge Gaps with Digital Agriculture

Ruben Remelgado, Vítězslav Moudrý, Elisa Padulosi, et al.

Published: 2023-12-23
Subjects: Agriculture, Biodiversity

The global expansion and intensification of food production threaten biodiversity, vital for ecosystem services and food security. The Kunming-Montreal Global Biodiversity Framework (GBF) advocates drastic changes in agricultural management, yet translating recommendations into local action is challenging. Biodiversity-friendly practices carry highly uncertain benefits, dissuading their adoption. [...]

Ecosystem functions and services provided by dung beetles: a global meta-analysis

Fevziye Hasan, Louis A Schipper, Kiri Joy Wallace, et al.

Published: 2023-12-19
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences

Dung beetles are known to carry out a range of ecosystem functions such as secondary seed dispersal, bioturbation, nutrient cycling, plant growth, pest and parasite control, and trophic regulation, many of which support key ecosystem services. Despite the globally purported significance of this group of insects for ecosystem functioning, there has been no quantitative synthesis to establish the [...]

The implementation of a new genomic assembly pipeline named Only The Best (otb) has effectively addressed various challenges associated with data management during the development and storage of genome assemblies. otb, which incorporates a comprehensive pipeline involving a setup layer, quality checks, templating, and the integration of Nextflow and Singularity. The primary objective of otb is to [...]

Sharing the burden: Cabbage stem flea beetle pest pressure and crop damage are lower in rapeseed fields surrounded by other rapeseed crops

Daniel J Leybourne, Antonia M C Pahl, Petra Melloh, et al.

Published: 2023-11-04
Subjects: Agriculture, Entomology, Life Sciences, Other Ecology and Evolutionary Biology

The cabbage stem flea beetle (Psylliodes chrysocephala) is a significant pest of rapeseed (Brassica napus). Feeding by adult P. chrysocephala can cause severe leaf damage and larval infestation can reduce stem strength, both of which impact crop growth and development, causing substantial yield losses and economic damage. The structure of the agricultural landscape can regulate herbivorous pest [...]

A Comprehensive Assessment of Verticillium Wilt of Potato: Present Status and Future Prospective

Shreejana KC, Amrit Poudel, Dipiza Oli, et al.

Subjects: Agricultural Science, Agriculture, Life Sciences, Plant Pathology, Plant Sciences

The fungal disease Verticillium wilt is a soil-borne pathogen that is caused by Verticillium dahliae. This disease affects a wide range of crops and can cause significant yield losses. Recent findings suggest that Verticillium wilt has been affecting potato crops in abundant demesne around the global world, including in North America, parts of Europe, and Asia. In some cases, the disease has been [...]

Yield declines and producer responses to shifting climate and economic conditions in Mexican coffee production

Katherine Ennis, Paulo Quadri, Kai Zhu, et al.

Coffee’s climate sensitivity contributes to extreme production and price fluctuations. However, as coffee is a perennial crop, producers have difficulty responding to short-term market shifts. Combining historical climate, production and price data from all coffee-growing municipalities in Mexico, we examined trends of climate and coffee production and then characterized and quantified coffee [...]

Developing systems theory in soil agroecology: Incorporating heterogeneity and dynamic instability

Ecosystem management is integral to the future of soils, yet anthropogenic drivers represent a key source of uncertainty in ecosystem models. First- and new-generation soil models formulate many soil pools using first-order decomposition, which tends to generate simpler yet numerous parameters. Systems or complexity theory, developed across various scientific and social fields, may help improve [...]

Maintenance and expansion of genetic and trait variation following domestication in a clonal crop

Oliver White, Manosh Biswas, Wendawek M. Abebe, et al.

Published: 2022-09-01
Subjects: Agriculture, Bioinformatics, Biosecurity, Genetics and Genomics, Genomics, Life Sciences, Plant Sciences

Clonal propagation enables favourable crop genotypes to be rapidly selected and multiplied. However, the absence of sexual propagation can lead to low genetic diversity and accumulation of deleterious mutations, which may eventually render crops less resilient to pathogens or environmental change. To better understand this trade-off, we characterise the domestication and contemporary genetic [...]

The light spectrum for plant cultivation: a source of colourful arguments

Pedro José Aphalo, Titta K Kotilainen

Published: 2022-05-30
Subjects: Agriculture, Food Science, Life Sciences

The concept of ``wasted illumination'' and its application to the design of light sources for plant cultivation is a good example of misuse of reductionism. Equating instantaneous rate of photosynthesis to crop yield is a prevailing but nonsensical idea, and in the case of the design of red plus blue light sources an extreme case of ignoring the multiple regulatory mechanisms and interactions [...]

The Global Forest Health Crisis: A Public Good Social Dilemma in Need of International Collective Action

Society is confronted by interconnected threats to ecological sustainability. Among these is the devastation of forests by destructive non-native pathogens and insects introduced through global trade, leading to the loss of critical ecosystem services and a global forest health crisis. We argue that the forest health crisis is a public good social dilemma and propose a response framework that [...]

Achieving global biodiversity goals by 2050 requires urgent and integrated actions

Paul Leadley, Andrew Gonzalez, Cornelia Krug, et al.

Human impacts on the Earth’s biosphere are driving the global biodiversity crisis. Governments are preparing to agree on a set of actions intended to halt the loss of biodiversity and put it on a path to recovery by 2050. We provide evidence that the proposed actions can bend the curve for biodiversity, but only if these actions are implemented urgently and in an integrated manner.

Flower strips increase the control of rosy apple aphids after parasitoid releases in an apple orchard

Kévin Tougeron, Louise Ferrais, Pauline Gardin, et al.

Mass releases of two parasitoid species, Aphidius matricariae and Ephedrus cerasicola, may provide an alternative measure to pesticides to control the rosy apple aphid Dysaphis plantaginea in organic apple orchards. As a proof of concept study, we tested if the presence of flower strips between apple tree rows could improve the action of three early parasitoid releases—and of other naturally [...]

Subjects: Agriculture, Life Sciences

In recent years, interest has increased in regenerative practices as a strategy for transforming food systems and solving major environmental problems such as biodiversity loss and climate change. However, debates persist regarding these practices and how they ought to be defined. This paper presents a framework for exploring the regenerative potential of food systems, focusing on how food [...]

A practical conservation tool to combine diverse types of evidence for transparent evidence-based decision-making

Making the reasoning and evidence behind conservation decisions clear and transparent is a key challenge for the conservation community. Similarly, combining evidence from diverse sources (e.g., scientific vs non- scientific information) into decision-making is also difficult. Our group of conservation researchers and practitioners has co-produced an intuitive tool and template [...]
