Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

open access: yesAdvanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

Cryptic destruction of India's native forests [PDF]

open access: yesConservation Letters, 2010
Abstract India sustains some of the world's most imperiled forests. The Forest Survey of India recently announced that forest cover in India had expanded by nearly 5% over the past decade. This result, while technically accurate, is misleading. The Forest Survey estimates forest cover by using automated algorithms
