Interglacial pollen records are valuable archives of past vegetation dynamics and provide important information about responses to different-than-today climates. pre-dating the Last Glacial Maximum (LGM) scarce on Swiss Plateau in contrast many available Late Holocene records. This is mainly due rapidly changing palaeo-environmental conditions throughout Quaternary low preservation potential ma...

Climate change is projected to trigger strong declines in the potential distribution of major tree species Europe. While minor natives have moved into spotlight as alternatives, their ecology often poorly understood. We use an ensemble modelling approach on a set promising native gain insights under different climate scenarios. Moreover, we identify urgency and altered distributions favor by co...

The equilibrium moisture content and specific gravity of Uludag fir (Abies bornmüelleriana Mattf.) hornbeam (Carpinus betulus L.) woods were investigated following heat treatment at different temperatures times. Two prediction models established based on the Aquila optimization algorithm back-propagation neural network model. To demonstrate effectiveness accuracy proposed model, it was compared...

The protection and propagation of rare endangered species are key to the preservation their population development; however, due scarcity individuals, potential effects status in whole forest ecosystem still poorly understood. Using data from a 60 × 140 m dynamic monitoring sample Carpinus tientaiensis (Betulaceae) Zhejiang Southeast China. We assessed distribution diameter at breast height (DB...

In this research, hornbeam chips were cooked under chemimechanical pulp (CMP) conditions, and the pulps were prepared at a yield level of 85%. The CMP pulps were separately bleached with hydrogen peroxide and sodium dithionite with and without treatment with DTPA. Then 60 gr/m 2 handsheets were made. The goal was to determine whether complementary bleaching with sodium dithionite improves optic...
