Subjects: Agriculture, Biodiversity, Economics

The UK government's Biodiversity Challenge Funds (BCF; including Darwin Initiative, Illegal Wildlife Trade Challenge Fund, and Darwin Plus) have funded hundreds of conservation projects across the Global South since the early 1990s. Increasingly, these projects include goals relating to human livelihoods, recognising the complex interrelationships between poverty reduction and biodiversity [...]

Physical Trait Variation in Hass Avocados Across Different Fruit Sizes

Juan Opazo, Gonzalo Riadi

Published: 2024-07-04
Subjects: Agriculture, Life Sciences

Hass avocados are globally consumed, nutrient-rich fruits. While current analyses mainly benefit the industry, there is a need for research focused on consumer advantages. Understanding the statistical relationships between the physical characteristics of avocados, particularly pulp content, can help consumers make better purchasing decisions. This study examines the physical attributes of Hass [...]

Beyond the buzz: A review of the prospects of replacing meat consumption with insect-based foods

Corentin Biteau, Tom Bry-Chevalier, Dustin Crummett, et al.

Published: 2024-04-04
Subjects: Agriculture, Food Science, Nutrition

The substantial environmental footprint of meat production means that dietary shifts are needed to reduce greenhouse gas emissions. Insects may offer one alternative. However, to deliver genuine benefits for sustainability of the food system, insects must first be widely accepted and consumed by the general public. In this review, we examine the necessary stages that need to be fulfilled before [...]

Have the environmental benefits of insect farming been overstated? A critical review

Corentin Biteau, Tom Bry-Chevalier, Dustin Crummett, et al.

Published: 2024-04-04
Subjects: Agricultural and Resource Economics, Agriculture, Food Science

Humanity's food system has an immense environmental impact, and insects have been frequently proposed as a more environmentally sustainable option. The industrialised farming of insects for livestock feed and human food has attracted the attention of industry, policymakers, and the scientific community. However, many of the benefits commonly mentioned by companies and proponents of insect farming [...]

Social cues and habitat structure influence the behavior of a non-social insect

Matteo Marcantonio, Stefano Masier, Argiris Kourtidis, et al.

Published: 2024-03-05
Subjects: Agriculture, Animal Sciences, Biodiversity, Entomology, Life Sciences

Habitat fragmentation and loss is a known threat to biodiversity. Their combined effect leaves organisms in small isolated patches of habitat, contributing to the current biodiversity crisis. The first response of animals to environmental change is typically behavioral. Beyond the physical elements of the environment, the "social landscape" shapes the spatial distribution of the habitats [...]

Thresholds and prediction models to support the sustainable management of herbivorous insects in wheat. A review

Daniel J Leybourne, Kate Storer, Abigail Marshall, et al.

Subjects: Agriculture, Entomology

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 [...]

otb: Creating a HiC/HiFi Pipeline to Assemble the Prosapia bicincta Genome

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.

Published: 2023-07-28
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.

Published: 2023-04-06
Subjects: Agricultural and Resource Economics, Agricultural Economics, Agriculture, Environmental Sciences, Environmental Studies, Geography, Life Sciences, Nature and Society Relations, Other Environmental Sciences

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: 2022-05-31
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 [...]
