Climatic adaptation of seed maturity in Scots pine and Norway spruce populations
Silva Fennica, 2001 Seed maturation of Scots pine and Norway spruce in a provenance experiment at Kortkeros (northern Russia) was examined by the X-ray method. Logarithmic relationships were found between seed anatomy development and long-term average thermal sum.

Insect Science, EarlyView.Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

Integrative Zoology, EarlyView.We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

Agricultural and Forest Entomology, EarlyView.We assess the effect of sanitation felling performed in 2022 in North‐Eastern Italy on bark beetle damage that occurred in 2023 across eight spruce forest types, as evaluated using multispectral satellite imagery. Bark beetle damage was reduced only at very high or very low sanitation felling rates.
