Bumblebee cost-effectiveness for sunflower pollination in isolation cages

Ekonomika Poljoprivrede (1979), 2010
The lack of pollinators during sunflower seed production in isolation cages can lower the seed yield up to 90%. That is why we analyzed the cost-effectiveness of bumblebee usage as pollinators.

Geoarchaeological characterisation of a Younger Dryas site in the Alpine uplands: Cornafessa rock shelter (Italy)

Geoarchaeology, Volume 38, Issue 1, Page 35-56, January/February 2023., 2023
Abstract The effects of the Younger Dryas (YD) fluctuation on Late Pleistocene hunter‐gatherers' settlement and subsistence systems in the southern Alps are poorly known. This is primarily due to the scarcity of archaeological sites dating from the YD, in contrast with the extensive evidence available from the lateglacial interstadial and the early ...

Animal pollination shapes fruits market features, seeds functional traits and modulates their chemistry

Scientific Reports
In this study, we experimentally addressed the impact of different pollination treatments on the morphological, reproductive and chemical traits of fruits and seeds of two crop species, the wild strawberry (Fragaria vesca L.) and cowpea (Vigna ...

Charting the landscape of the environmental exposome

iMeta, Volume 1, Issue 4, December 2022., 2022
We describe the biological and chemical components of the environmental exposomes in three major environmental matrices that are highly relevant to human and social‐economical health—air, soil, and water. We discuss how different exposome components can interact with each other. Finally, we propose a list of outstanding challenges to be tackled to push

A Comprehensive Review of Current Robot- Based Pollinators in Greenhouse Farming [PDF]

arXiv
The decline of bee and wind-based pollination systems in greenhouses due to controlled environments and limited access has boost the importance of finding alternative pollination methods. Robotic based pollination systems have emerged as a promising solution, ensuring adequate crop yield even in challenging pollination scenarios.

Cost estimation model for isolation and segregation of non‐genetically modified corn and soybeans at country grain elevators

Cereal Chemistry, EarlyView.
Abstract Background and Objective Corn and soybean meal are important ingredients for livestock and poultry feed. Feed producers who wish to produce non‐genetically modified (non‐GM) feed must segregate ingredients, especially corn and soybeans, throughout the supply chain.
