Genetics of Alternating Sexes in Walnuts

Scientists have uncovered a genetic mechanism in walnuts and their ancestors that has remained stable for 40 million years. Male-first or female-first flowering, balanced by a single genetic locus, parallels sex determination in animals. This evolutionary trait ensures genetic diversity,…

An inexpensive fix for struggling wildflowers

Raking dead grass (thatch) helps native plants grow by improving light access, according to a study. In three-year tests, raking increased plant diversity, reduced invasive grasses, and boosted wildflowers. While it also raised some invasive wildflowers, raking offers a low-cost,…

Land use in tropical regions: Biodiversity loss due to agricultural trade three times higher than thought

Intensive land use for agriculture in tropical regions, driven by international trade, has caused over 90% of biodiversity loss since 1995, far exceeding previous estimates of 20-30%. Research using satellite data highlights hotspots like Brazil, Indonesia, and Madagascar. Solutions include…
