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

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.

In this paper, we present the results of field investigations on suitability three types trunk traps (‘Commercial 1’, ‘Commercial 2’, and ‘Prototype’) for capturing spongy moth (Lymantria dispar) larvae in two areas with different climates forest ecosystems. NE Slovenia, which were characterized by Pannonian climate regular rainfall during research period (2022–2024), 2’ trap was most suitable capture old larvae. a 20–30 m tall trees dominant species Quercus robur, Carpinus betulus, Pinus sylvestris, it proved easy to set trunks change their parts upon inspection captures. 1’ be less suitable, since bags quickly filled water downpours consequently fell out traps. ‘Prototype’ an area Mediterranean (Greece), where (Quercus spp.) smaller (3–4 m) both younger older could more easily come into contact sticky surface inner part trap, longer-lasting effectiveness possible drier climate.

As one of the important types forest resources, mapping stock volume (FSV) in larch (Larix decidua) forests holds significant importance for resource management, carbon cycle research, and climate change monitoring. However, accuracy FSV using common spectral texture features is often limited due to their failure fully capturing seasonal changes growth characteristics vegetation. Phenological can effectively provide essential information regarding status forests. In this study, multi-temporal Sentinel-2 satellite imagery were initially acquired Wangyedian Forest Farm Chifeng City, Inner Mongolia. Subsequently, various phenological extracted from time series variables constructed by Gaussian Process Regression (GPR) Savitzky–Golay filters, stepwise differentiation, Fourier transform techniques. The alternative further refined through Pearson’s correlation coefficient analysis forward selection algorithm, resulting six groups optimal subsets. Finally, four models including Random (RF), K-Nearest Neighbors (KNN), Support Vector Machine (SVM), Multiple Linear (MLR) algorithms developed estimate FSV. results demonstrated that incorporating significantly enhanced model performance, with SVM exhibiting best performance—achieving an R2 value 0.77 along RMSE 46.36 m3/hm2 rRMSE 22.78%. Compared without features, inclusion these led a 0.25 increase while reducing 10.40 5%. Overall, integration feature not only improves but also has potential implications delaying saturation phenomena.

Temperature and food quality are the most important environmental factors determining performance of herbivorous insects. The objective our study was to evaluate responses spongy moth (formerly known as gypsy moth) [Lymantria dispar L. (Lepidoptera: Erebidae)] simultaneous variation in these two factors. From hatching fourth instar, larvae were exposed three temperatures (19 °C, 23 28 °C) fed four artificial diets that differed protein (P) carbohydrate (C) content. Within each temperature regime, effects nutrient content (P+C) ratio (P:C) on development duration, larval mass, growth rate, activities digestive proteases, carbohydrases, lipase examined. It found had a significant effect fitness-related traits physiology larvae. greatest mass highest rate obtained at °C high-protein low-carbohydrate diet. A homeostatic increase activity observed for total protease, trypsin, amylase response low substrate levels modulation overall enzyme detected only with diet quality. decrease P:C affected coordination indicated by significantly altered correlation matrices.
