Newswise — To reduce biodiversity loss in agricultural landscapes, more sustainable and environmentally friendly agricultural practices are needed. A research team from the Universities of Göttingen and Hohenheim in Germany, and Venda in South Africa, investigated how ecosystem services such as pollination could be improved in macadamia plantations. The scientists showed that a certain design of plantations – for instance, how the rows of trees are arranged, the varieties, and the integration of semi-natural habitats in and around the plantations – can increase the pollination performance of bees. The results were published in the Journal of Applied Ecology.

The research team first investigated the role of insect pollinators in the nut production of macadamia trees. “Insect pollination of macadamia flowers is essential for production. A complete loss of insect pollinators would reduce the amount of nuts by 75 percent,” says Professor Ingo Grass, Head of the Department of Ecology of Tropical Agricultural Systems at the University of Hohenheim. To find out which conditions encourage pollinators, the researchers observed and counted the bees and other insects on the macadamia flowers. “Surprisingly, it is less important how many honey bee colonies were established in the vicinity. The more important factor is how large the proportion of semi-natural habitats is in the vicinity of the plantation, since the majority of pollinators fly from the semi-natural habitats into the plantations,” says first author Mina Anders, PhD student in Functional Agrobiodiversity, University of Göttingen.

The arrangement of the rows of trees in the plantations is therefore particularly important: 80 percent more nuts grew at the edge of the plantation, ie land that borders on semi-natural habitats, than in the middle of the plantation. Directly after flowering, the nut formation increased more than threefold in tree rows planted at right angles to semi-natural habitats, compared to rows planted parallel to the habitats. “Pollinators move more easily from their habitat to the plantations when the rows are perpendicular, as they prefer to fly along the rows rather than through them,” Anders explains. Agronomic practices such as artificial irrigation, on the other hand, did not increase the initial nut formation.

“Given the urgency to reduce the harmful environmental impacts of agricultural practices, we emphasise the enormous potential of supporting ecology through intelligent plantation design and the restoration and maintenance of semi-natural habitats in plantations and the surrounding landscape,” says Professor Catrin Westphal, Head of Functional Agrobiodiversity.

Moon Landing

In a significant milestone for space exploration, Firefly Aerospace’s Blue Ghost Mission 1 made a successful landing on the Moon at 3:34 a.m. EST on Sunday. Positioned near the volcanic feature of Mons Latreille within Mare Crisium, a vast basin exceeding 300 miles in diameter, this event marks a pivotal moment in NASA’s initiatives concerning lunar exploration.

This successful moon landing represents the first delivery under NASA’s Commercial Lunar Payload Services (CLPS) initiative for Firefly Aerospace, and it adds another achievement to the Artemis campaign aimed at returning humans to the Moon. The Blue Ghost lander now rests upright and stable on the lunar surface, ready to begin its suite of scientific operations.

The Blue Ghost craft is carrying ten cutting-edge NASA science and technology instruments designed to perform a variety of functions over approximately one lunar day, which translates to about 14 Earth days. Acting Administrator Janet Petro highlighted the importance of this mission, stating, “This incredible achievement demonstrates how NASA and American companies are leading the way in space exploration for the benefit of all.” The lessons learned from this mission will enhance future safety protocols for scientific exploration on the Moon and beyond.

Following its launch from NASA’s Kennedy Space Center on January 15, the Blue Ghost traveled over 2.8 million miles. During this journey, it downlinked more than 27 gigabytes of data while conducting several critical science operations. One notable achievement included signal tracking from the Global Navigation Satellite System (GNSS) at a record distance of 246,000 miles, validating the potential for similar positioning systems to be used effectively on the Moon.

Nicky Fox, associate administrator for science at NASA Headquarters, emphasized the significance of this mission in laying the groundwork for future human presence on the Moon: “The science and technology we send to the Moon now helps prepare the way for future NASA exploration and long-term human presence to inspire the world for generations to come.”

The instruments aboard the Blue Ghost will perform a variety of tasks during their lunar surface operations, including testing advanced drilling technology, collecting regolith samples, and developing lunar dust mitigation strategies. The insights gained from these experiments will contribute to our understanding of how space weather and cosmic forces interact with Earth.

As operations continue, the team intends to capture stunning imagery of the lunar sunset and investigate the behaviors of lunar dust during dusk conditions—an occurrence previously documented by Apollo 17 astronaut Eugene Cernan. Following the lunar sunset, the lander will remain functional for several hours into the lunar night.

Firefly Aerospace’s CEO, Jason Kim, expressed gratitude to NASA for the partnership and outlined the significance of this mission. “Blue Ghost’s successful Moon landing has laid the groundwork for the future of commercial exploration across cislunar space,” he stated, adding, “We’re now looking forward to more than 14 days of surface operations to unlock even more science data that will have a substantial impact on future missions to the Moon and Mars.”
