The Presence of IUCN Red List Tree Species in Dependence of Site Characteristics in the Vietnamese Cat Ba National Park

Diversity, 2020
Rare or endangered tree species are important components of forest ecosystems and play a crucial role in management and conservation. Understanding what influences their presence is critical for managers, conservationists and planners.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

National Red Lists: the largest global market for IUCN Red List Categories and Criteria [PDF]

Endangered Species Research, 2008
The 2 major challenges currently confronting the International Union for Conservation of Nature (IUCN) with regard to the 'red listing' process are the taxonomic, and the geographic growth of the data base. Taxonomic growth refers to the objective of gradually assessing the risk of extinction of all the world's species and periodically repeating such ...

Ambiguity in guideline definitions introduces assessor bias and influences consistency in IUCN Red List status assessments

Frontiers in Ecology and Evolution, 2015
The IUCN Red List is the most widely used tool to measure extinction risk and report biodiversity trends. Accurate and standardised conservation status assessments for the IUCN Red List are limited by a lack of adequate information; and need consistent ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
