Autocorrelated exogenous factors and the detection of delayed density dependence

, 2003
DOI: 10.1890/02-0557© Ecological Society of AmericaCoupled trophic interactions with specialist predators or resources are thought to be primarily responsible for generating delayed density dependence.

Large trees are surrounded by more heterospecific neighboring trees in Korean pine broad-leaved natural forests

Scientific Reports, 2018
Negative conspecific density dependence is one of the principal mechanisms affecting plant performance and community spatial patterns. Although many studies identified the prevalence of density dependent effects in various vegetation types by analyzing ...

Frequency and density-dependent selection on life-history strategies--a field experiment. [PDF]

PLoS ONE, 2008
Negative frequency-dependence, which favors rare genotypes, promotes the maintenance of genetic variability and is of interest as a potential explanation for genetic differentiation.

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Negative density dependence mediates biodiversity–productivity relationships across scales [PDF]

, 2017
Regional species diversity generally increases with primary productivity whereas local diversity–productivity relationships are highly variable.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Habitat filtering masks the detection of phylogenetic and functional density dependence on seedling survival across seasons in a subtropical forest, Southwestern China

Ecological Processes
Background Negative density dependence and habitat filtering are crucial mechanisms driving species coexistence and community assembly. However, empirical evidence regarding how habitat filtering interacts with density dependence remains limited ...
