Welti, Ellen; Kaspari, Michael Humans, caterpillars, and fungal pathogens agree, food tastes better with a pinch of salt. While humans are omnivores and can obtain sodium when eating animal products like meat and dairy, herbivores and detritivores have fewer salty menu items. This is why porcupines will eat backpackers’ sweaty hiking boots, deer come to salt licks, and sweat bees seek human perspiration. Unlike animals, … Continue reading Herbivores and fungal pathogens take it with a grain of salt
Rebecca K. Vandegeer, Ximena Cibils-Stewart, Richard Wuhrer, Susan E. Hartley, David T. Tissue, Scott N. Johnson Farmers face many challenges in the management of their crops, including insect pests and drought that can both drastically reduce yields. Pest management using chemical pesticides can be costly, environmentally damaging and overuse can lead to pesticide resistance. An alternative management option may be to harness naturally occurring plant-based … Continue reading Caterpillar pests find leaf silicon particles less appealing than drought-induced changes to their host plants
Van Leeuwen, Casper; Mulder, Andrea; van Aalderen, Roland Seed dispersal by animals is important for the transport of plant seeds to new locations. Many animals ingest, transport and defecate viable seeds – which can lead to colonization in fragmented habitats, expand plant ranges in response to global changes, or ensure space for a next generation. Many fruit-eating birds and mammals are well-known seed dispersers, but … Continue reading How far can fish transport plant seeds?

Nacho Villar, Claudia Paz, Valesca Zipparro, Sergio Nazareth, Leticia Bulascoschi, Elisabeth S. Bakker and Mauro Galetti Tropical forests play a critical role in the global nitrogen cycle. These forests are populated by many animals that feed mostly on fruits, including some of the largest mammals such as tapirs and peccaries. Now a new study in the Atlantic Forest of Brazil has found that these so … Continue reading Frugivory regulates the nitrogen cycle in tropical forests
Zhongxiang Sun, Yibin Lin, Rumeng Wang, Qilin Li, Qi Shi,Scott R. Baerson, Li Chen, Rensen Zeng and Yuanyuan Song Co-evolution of complex plant-insect interactions plays a vital role in structuring terrestrial ecosystems. Volatile chemicals emitted by plants play key roles in signaling between plants and other organisms. Upon herbivore attack, plants increase emission of herbivore-induced plant volatiles (HIPVs) that protect plants by eliciting both direct … Continue reading Insect larvae use herbivore-induced plant volatiles as inducers to disarm plant chemical defense
