Dieback in temperate forests is understudied, despite this biome predicted to be increasingly affected by more extreme climate events a warmer world. To evaluate the potential drivers of dieback we reconstructed changes radial growth and intrinsic water-use efficiency (iWUE) from stable isotopes tree rings. Particularly, compared size, radial-growth trends, responses (temperature, precipitation...
The city longhorn beetle (Aeolesthes sarta) (CLB) (Coleoptera – Cerambycidae) is a polyphagous invasive pest of both healthy and suppressed broadleaved trees in central Asia. CLB causes great degree damage the countries its origin. To understand this better way, detailed review study has been conducted to gather all valuable information related CLB. This covers main aspects CLB, morphology, eco...

The estimation of species composition and species-specific stem volumes are critical components many forest inventories. use airborne laser scanning with multiple spectral channels may prove instrumental for the cost-efficient retrieval these variables. In this study, we scanned a boreal using two channels: 532 nm (green) 1064 (near infrared). data was used in two-step methodology to (1) classi...
Stumps left behind after the felling of trees represent an important source renewable energy that could be used for fuel mixtures as a sustainable solution. The subject this research was to determine influence tree species, stump diameter size, and subsoil on time required processing. Evaluated parameters included mean one stump’s processing; processing based diameter; different soil types spec...
Litter quality is often considered the main driver of rates of decomposition. Litter decomposes faster in its home environment than in any other environment, which is called the home-field advantage (HFA). However, evidence for this phenomenon has not been universal. In addition, litter mixtures of different species can induce a non-additive effect (NAE) on decomposition processes. However, the...
