First Fossil Fokienia (Cupressaceae) in South China and Its Palaeogeographic and Palaeoecological Implications

Frontiers in Earth Science, 2021
Fokienia A. Henry & H. H. Thomas is a monotypic genus of the Cupressoideae Rich. ex Sweet (Cupressaceae), native to subtropical evergreen mesophytic forests in South China, northern Laos and Vietnam. The fossil record of Fokienia is very scanty, with

Tree defence and bark beetles in a drying world: carbon partitioning, functioning and modelling. [PDF]

, 2020
Drought has promoted large-scale, insect-induced tree mortality in recent years, with severe consequences for ecosystem function, atmospheric processes, sustainable resources and global biogeochemical cycles.

Post‐LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor

Cytoskeleton, EarlyView.
ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit

Cryopreservation of Abies alba embryogenic tissues by slow-freezing method

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2022
Embryogenic tissues of Abies alba Mill. were cryopreserved using the slow-freezing approach. Four cell lines were incubated for 24 h on a medium with 0.5 M sorbitol and pre-treated with 5% DMSO. Subsequently, the tissues were frozen at a cooling rate of

Developing a macroecology for human‐altered ecosystems

Ecography, EarlyView.
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

Early genome duplications in conifers and other seed plants

Science Advances, 2015
A new phylogenomic approach reveals that conifer genomes are duplicated despite rare polyploidy among extant species. Polyploidy is a common mode of speciation and evolution in angiosperms (flowering plants). In contrast, there is little evidence to date

Alpine ungulates adjust diel activity to the natural return of wolves amid anthropogenic pressures

Ecography, EarlyView.
As wolves recolonise their historical range across Europe, ungulates face predation once more – but in landscapes profoundly altered by human activity. This shift raises crucial questions about their capacity to express adaptive antipredator behaviours.

Does biotic resistance govern forest invasions by bark and ambrosia beetles?

Ecography, EarlyView.
The theory of biotic resistance states that community diversity promotes resistance to biological invasions. This theory has been widely explored for its ability to explain variation in habitat invasibility to non‐native plant species and while the theory holds in some systems, it does not in others.

Experimental Analysis of Fire Behavior in Pine Forests and Agricultural Fields: Large‐Scale Tests Conducted Within the European TREEADS Project

Fire and Materials, EarlyView.
ABSTRACT Two large‐scale experiments investigated fire spread mechanisms in vegetation ground fires in a pine forest and an agricultural field within the European TREEADS project. The tests, conducted in Saxony‐Anhalt and Brandenburg, targeted regions with dry, sandy soils and extensive pine stands and aim to improve suppression strategies and wildfire
