A process-based model of conifer forest structure and function with special emphasis on leaf lifespan [PDF]
We describe the University of Sheffield Conifer Model (USCM), a process-based approach for simulating conifer forest carbon, nitrogen, and water fluxes by up-scaling widely applicable relationships between leaf lifespan and function. The USCM is designed

Ips typographus showed lower reproductive output in an occasional host (Pinus sylvestris) under laboratory conditions, and did not prefer its main host (Picea abies) over P. sylvestris in two‐choice bioassays. Abstract BACKGROUND The Eurasian spruce bark beetle, Ips typographus, is one of the most serious pests of Norway spruce (NS, Picea abies), with ...

Geochemical analysis of Cenozoic fossil conifers at high latitudes: Implications for molecular preservation and environmental change [PDF]
Fossil materials record ancient life and their adapted environment. Arctic plant fossils are critical for our understanding of the Earth’s paleoenvironment when high latitudes were under ice-free conditions.

Shaping future forests: how can ecophysiology support climate‐smart forest management?
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

Effects of Heat Treatment on Thermal Decomposition and Combustion Performance of Larix spp. Wood
Larix spp., a wood species of low dimensional stability, was heat-treated in nitrogen at 180 to 210 °C for 6 h. Changes in the thermal decomposition and combustion behaviors of the wood after heat treatment were investigated by TGA, SEM, FTIR, and cone ...

The study identified 41 priority conservation grids and 8 critical conservation gaps not covered by national reserves for medicinal gymnosperms. We proposed a practical, multi‐dimensional framework for their conservation. ABSTRACT To elucidate the geographical distribution patterns and hotspots of medicinal gymnosperms in China, providing a scientific ...
