Cost of parasite exposure depends on host ontogeny 寄生接觸的代價依賴於宿主發育階段
Ecological Entomology, Volume 51, Issue 3, Page 592-603, June 2026.The cost of parasite exposure varies across host developmental stages, demonstrating that ontogeny influences the expression of non‐consumptive effects (NCEs). Mite exposure resulted in consumptive effects in fly eggs and NCEs in early‐stage pupae; mite longevity was comparable when provisioned with pupae or water but increased when provisioned with ...

Policy, Waste, and Power: Textile Dumping in Chile's Atacama Desert
Latin American Policy, Volume 17, Issue 2, June 2026.ABSTRACT Globally, 87% of textile fibers end up incinerated or in landfills, with Chile bearing the brunt of this crisis. Every year, 39,000 tons of discarded clothing are illegally dumped in the Atacama Desert, turning it into a sacrifice zone for the Global North's waste economy.

New Phytologist, Volume 250, Issue 6, Page 3990-4001, June 2026.Summary Beyond fully mycoheterotrophic plants, many green plants may also obtain carbon from fungal partners. However, bulk stable isotope analyses often lack sufficient resolution in arbuscular mycorrhizal and rhizoctonia‐associated orchid systems, limiting inference of fungal‐derived organic nutrient acquisition.
