Frugivory regulates the nitrogen cycle in tropical forests

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

Insect larvae use herbivore-induced plant volatiles as inducers to disarm plant chemical defense

Insect larvae use herbivore-induced plant volatiles as inducers to disarm plant chemical defense

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
