Global warming is affecting the phenological cycles of plants and animals, altering complex synchronization that has co-evolved over thousands years between interacting species trophic levels. Here, we examined how warmer winter conditions affect timing budburst in six common European trees hatching a generalist leaf-feeding insect, spongy moth

Abstract An increase in biotic interactions towards lower latitudes is one of the most consistent patterns ecology. Higher temperatures and more stable climatic conditions at low are thought to enhance interactions, accelerating biological evolution leading stronger anti-herbivore defences plants. However, some studies report contradictory findings, highlighting need for further investigation into underlying mechanisms. We used a combination field observations feeding trials controlled environments investigate effect climate on chemical insect herbivory pedunculate oak ( Quercus robur L.) throughout its geographic range Europe, while controlling physical defences. The concentration lignin, flavonoids, total phenolics increased significantly with temperature, whereas both weight spongy moth Lymantria dispar larvae were negatively influenced by temperature. Lignin positively it had no herbivory. found evidence strong positive relationships between growth leaf Our study underscores complexity plant–herbivore along gradients highlights research disentangle these intricate relationships.

North American forest systems are significantly impacted by spongy moths ( Lymantria dispar Linnaeus). It is unclear, nevertheless, how the invasion risks of from Asia and Europe in relative to each other. In this study, we compared potential ranges (ASM) those (ESM) America, investigated range shifts between America (NASM) ASM ESM. ESM would occupy larger than NASM, i.e., 7.16 6.98 times, respectively. Thus, one should not undervalue invasive posed Europe. Compared ESM, displayed America. likely due ASM’s tolerance more variable climates. Consequently, even though was recently introduced it’s possible that former has higher risk American.
