Effects of post-fire logging on forest surface air temperatures in the Siskiyou Mountains, Oregon, USA [PDF]

, 2010
Following stand-replacing wildfire, post-fire (salvage) logging of fire-killed trees is a widely implemented management practice in many forest types. A common hypothesis is that removal of fire-killed trees increases surface temperatures due to loss of ...

Demonstration of methods used to create binary Conifer Refugia and Conifer Absence variable. [PDF]

, 2020
Conifer Refugia is defined by the presence of post-fire mature conifers, and Conifer Absence contained no live mature trees following the fire. Panels A-D span the same extent within the 2012 High Park fire.

Linking community structure and climate vulnerability in desert plant assemblages of southern California

American Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Taxonomic reassessment of fossil Sequoia and Protosequoia from the Upper Miocene of Central Honshu, Japan, with implications for leaf morphological variation in extant S. sempervirens

American Journal of Botany, EarlyView.
Abstract Premise Since its emergence in the Mesozoic, Sequoia (Cupressaceae) has been considered to possess conserved leaf morphology. However, recent studies have shown that the leaves of extant S. sempervirens become smaller, with a scale form, with increasing tree height.

Changing winter climate and snow conditions induce various transcriptional stress responses in Scots pine seedlings

Frontiers in Plant Science, 2022
In northern boreal forests the warming winter climate leads to more frequent snowmelt, rain-on-snow events and freeze-thaw cycles. This may be harmful or even lethal for tree seedlings that spend even a half of the year under snow.
