Biodiversity relationships in three structural components in a beech forest of Fagus grandifolia subsp. mexicana

Botan‪ical Sciences, 2019
Background: Several studies have called attention to beech forest conservation and restoration in Mexico. Human activities (e.g., logging and grazing) have perturbed the few beech forests that persist in the Sierra Madre Oriental, Mexico. However, basic

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

The nitrogen/phosphorus and the succession of phytoplankton in two lakes located in the alluvial prairie of main river in Germany

Revista Facultad de Ingeniería Universidad de Antioquia, 2006
Variation in seasonal nitrogen/phosphorus ratio and phytoplankton community succession were compared between March and November 1997 in a lake directly connected to the Main River and in another lake without direct connection.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Ruderal succession starting at different seasons

Acta Societatis Botanicorum Poloniae, 2014
Succession experiments were carried out in 1 m2 sized plots on three different soils (S = sand. SCL = silty clayey loam, CL = clayey loam). Vegetation was allowed to grow for 9 years, starting at different dates between 18.06.1969 and 1.04.1971.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Dispersal and establishment both limit colonization during primary succession on a glacier foreland [PDF]

, 2009
Plant colonization can be limited by lack of seeds or by factors that reduce establishment. The role of seed limitation in community assembly is being increasingly recognized, but in early primary succession, establishment failure is still considered ...

Assemblages of Collembola across a 130-year chronosequence of beech forest

Soil Organisms, 2011
Although microarthropods dominate forest floor faunas in both diversity and abundance, long-term aspects of forest cycles have been widely neglected in soil ecological research in the past.

Chronosequence Resampling Elucidates Tree Community and Forest Structure Recovery Patterns in Restored Tropical Rainforest

Ecology and Evolution
Forest restoration is an essential tool for conserving biodiversity in tropical regions; yet, restoration outcomes in the Afrotropics remain largely understudied.
