Origin of Intra-annual Density Fluctuations in a Semi-arid Area of Northwestern China

Frontiers in Plant Science, 2021
Intra-annual density fluctuation (IADF) is a structural modification of the tree ring in response to fluctuations in the weather. The expected changes in monsoon flow would lead to heterogeneous moisture conditions during the growing season and increase ...

Host preferences of non‐native Acalolepta aesthetica (Coleoptera: Cerambycidae) on the Island of Hawaiʻi

Agricultural and Forest Entomology, EarlyView.
Acalolepta aesthetica is a non‐native cerambycid established on the Island of Hawaiʻi. We show its preferred hosts are woody species that are highly valued for agricultural, horticultural and cultural uses. We used a resource selection function to estimate host preferences and found that kukui (Aleurites moluccanus), the state tree, was preferred ...

Apical control of xylem formation in the pine stem. I. Auxin effects and distribution of assimilates

Acta Societatis Botanicorum Poloniae, 2014
The effect of IAA upon cambial activity, xylem differentiation and translocation of assimilates from the lateral shoot was investigated in spring and late summer in decapitated and ring-barked young trees of Pinus silvestris in the forest stand ...

Intra-annual cambial activity and carbon availability in stem of poplar [PDF]

Tree Physiology, 2009
Cambial activity is influenced by many environmental and physiological factors and among them, carbon acts as a source of energy for the growing meristems. This work has focused on the intra-annual stem growth of poplar compared with the carbon available for xylogenesis processes in cambium and outer wood.

Attraction of Phoracantha mastersi (Coloeptera: Cerambycidae) to copulation‐associated olfactory stimuli

Agricultural and Forest Entomology, EarlyView.
Damage caused by Phoracantha mastersi larvae are the primary cause of forest decline in Australia's subalpine forests. Behaviour of male adult beetles was tested in response to a suite of commercial semiochemicals and conspecifics engaged in active copulation within a Y‐maze.

Tree Growth Under Climate Change: Evidence From Xylogenesis Timings and Kinetics

Frontiers in Plant Science, 2020
Tree growth is one of the most studied aspects of tree biology, particularly secondary growth. In the Mediterranean region, cambial activity is mostly determined by water availability.

Therapeutic Bark Gouging as an Effective Complement for the Management of Ips typographus and Pityogenes chalcographus While Preserving Habitat for Secondary Scolytine (Coleoptera: Curculionidae) Species

Journal of Applied Entomology, EarlyView.
ABSTRACT Norway spruce will likely remain an important tree species in Europe over the next few decades despite efforts to transform forests and reduce its distribution range more to its natural range. Consequently, Ips typographus will remain one of the most relevant forest pests the management of which will become increasingly challenging due to ...

Rain exclusion affects cambial activity in adult maritime pines [PDF]

Agricultural and Forest Meteorology, 2017
Abstract Drought frequency and intensity are expected to increase in the Mediterranean basin with unforeseen impacts on forest ecosystems. In this study, we investigated the effect of a rain exclusion experiment on the growth dynamics of adult maritime pine trees. The rain exclusion experiment took place from March to October 2014.

Tree growth response and adaptation to climate change and climate extremes: From canopy to stem

Journal of Integrative Plant Biology, EarlyView.
This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...

Perception of gravity expressed by production of cambial callus in ash (Fraxinus excelsior L) internodes

Acta Societatis Botanicorum Poloniae, 2011
In ash internodes isolated from vertical stems during winter dormancy, cambial activity was stimulated by applying an aqueous solution of auxin to the apical end and water to the basal end.
