Interpopulation Variation in Egg Mortality in Response to Hot and Dry Conditions in North American Populations of the Invasive Tiger Mosquito, Aedes albopictus

Ecology and Evolution
How wild organisms are responding to climate change is one of the most pressing issues of the 21st century. As ectotherms, insects are particularly vulnerable to increases in temperature and extreme weather events because their fitness and survival are ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Insect responses to seasonal time constraints under global change are facilitated by warming and counteracted by invasive alien predators

Scientific Reports
In seasonal environments, organisms with complex life cycles not only contend with seasonal time constraints (TC) but also increasingly face global change stressors that may interfere with responses to TC.

Five-year carry-over effects in dune slack vegetation response to hydrology

Ecological Indicators
Dune slacks are biodiverse seasonal wetlands within sand dune systems, strongly influenced by the dynamics of the local groundwater regime. Future climate predictions indicate strong adverse impact on the hydrology and therefore ecology of these wetland ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Sex-dependent carry-over effects on timing of reproduction and fecundity of a migratory bird

, 2016
Life of many organisms flows as a sequence of annual cycles. Timing of cyclical events is shaped by natural selection also via the domino effects that any life history stage has on the stages that follow. Such 'carry-over effects' have major consequences

Economic and Environmental Feasibility of Variable Rate Nitrogen Fertilizer Application with Carry-Over Effects

Journal of Agricultural and Resource Economics, 1998
This study evaluates the long-term profitability and environmental impacts of variable rate versus uniform nitrogen application in seed potato production with nitrogen carry-over effects included.

Immediate and carry-over effects of increased soil frost on soil respiration and microbial activity in a spruce forest

Soil Biology and Biochemistry, 2019
Increased soil frost associated with winter climate change could have immediate and carry-over effects on biological processes in high-altitude forest soils, but the nature of these processes remain poorly understood.

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 ...

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
