Ecologists have discovered that the food hoards pygmy owls collect in nest-boxes (‘freezers’) for winter rot due to high precipitation caused by heavy autumn rains and if the hoarding has been initiated early in the autumn. The results of the study show that climate change may impair predators’ foraging and thus decrease local overwinter survival.Associated journal article: Giulia Masoero, Toni Laaksonen, Chiara Morosinotto, Erkki Korpimäki. Climate change and perishable food hoards of an avian predator: Is the freezer still working? Global Change Biology, 2020; DOI: 10.1111/gcb.15250

Farmers around the world are looking for innovative methods to save water, reduce costs and produce higher yields. No-till farming is a popular practice to improve soil quality and reduce soil erosion. Instead of using a plow to disturb soil before planning, it employs a drill or alternative equipment to grow crops without breaking the ground.
Is no-till growing as great as it’s made out to be? Should it be adopted by all to help the Earth? The answer is yes and no. What it really comes down to is the type of no-till farming, and whether it is being used in collaboration with other environmental conservation practices.

Global changes in land use are disrupting the balance of wild animal communities in our environment, and species that carry diseases known to infect humans appear to be benefiting, finds a new study.Associated journal article: Rory Gibb, David W.

Plants are factories that manufacture yield from light and carbon dioxide — but parts of this complex process, called photosynthesis, are hindered by a lack of raw materials and machinery. To optimize production, scientists have resolved two major photosynthetic bottlenecks to boost plant productivity by 27 percent in real-world field conditions, according to a new study. This photosynthetic hack has also been shown to conserve water.Associated journal article: Patricia E. López-Calcagno, Kenny L. Brown, Andrew J. Simkin, Stuart J. Fisk, Silvere Vialet-Chabrand, Tracy Lawson, and Christine A. Raines. Stimulating photosynthetic processes increases productivity and water-use efficiency in the field.

An unexpected partnership between one of the largest dairy cooperatives in America and a technology powerhouse that is more often associated with cubical farms than actual farms is taking on some of the biggest threats to the US food system to help farmers produce more food, more profitably and more sustainably.

Human changes to the environment have been linked to widespread pollinator declines. New research shows that intensive land use will further decrease pollination and reproductive success of wild plants, especially of those plants that are highly specialized in their pollination.Associated journal article: Joanne M.
