Seed density and priority effects outweigh limiting similarity and diversity in contributing biotic resistance to invasion [PDF]

NeoBiota
Despite numerous ecological theories proposed to explain plant invasion dynamics, few studies have evaluated multiple mechanisms simultaneously within a single experimental framework.

African Grass Invasion Threatens Tropical Wetland Biodiversity: Experimental Evidence from Echinochloa pyramidalis Invasion in a Mexican Ramsar Site

Grasses
African grasses deliberately introduced for cattle forage have become among the most destructive invaders of tropical wetlands globally, yet invasion mechanisms and management strategies remain poorly understood.

Habitat augmentation drives secondary invasion: an experimental approach to determine the mechanism of invasion success

Ecology, 2016
AbstractThe entry of secondary invaders into, or their expansion within, native communities is contingent on the changes wrought by other (primary) invaders. When primary invaders have altered more than one property of the recipient community, standard descriptive and modeling approaches only provide a best guess of the mechanism permitting the ...

Diverse Ecological Strategies Increase Invasion Resistance in an Experimental Grassland Restoration

Ecology and Evolution
Understanding how the characteristics of native plant communities influence invasion is a pressing question, with implications for theory and management.

Purifying selection shapes the dynamics of P-element invasion in Drosophila simulans populations

Genome Biology
Background Transposable elements (TEs) are DNA sequences that can move within a host genome. Many new TE insertions have deleterious effects on their host and are therefore removed by purifying selection.

A forward genetic screen reveals a primary role for Plasmodium falciparum Reticulocyte Binding Protein Homologue 2a and 2b in determining alternative erythrocyte invasion pathways.

PLoS Pathogens, 2018
Invasion of human erythrocytes is essential for Plasmodium falciparum parasite survival and pathogenesis, and is also a complex phenotype. While some later steps in invasion appear to be invariant and essential, the earlier steps of recognition are ...

Admixture is a driver rather than a passenger in experimental invasions [PDF]

Journal of Animal Ecology, 2016
Genetic admixture propels invasions of Callosobruchus maculatus across experimental landscapes.In Focus: Wagner, N.K., Ochocki, B.M., Crawford, K.M., Compagnoni, A. & Miller, T.E.X. (2017) Genetic mixture of multiple source populations accelerates invasive range expansion.

An Experimental Protocol for the Boyden Chamber Invasion Assay With Absorbance Readout

Bio-Protocol
The phenomenon of cell invasion is an essential step in angiogenesis, embryonic development, immune responses, and cancer metastasis. In the course of cancer progression, the ability of neoplastic cells to degrade the basement membrane and penetrate ...

H-ferritin: A new cytoprotective antioxidant strategy via detoxification of hydrogen peroxide to oxygen

Nano Research
It is well reported that cellular ferritin reduces the intracellular oxidative stress by sequestering excess ferrous ions, preventing them from participating in Fenton reactions that generate damaging harmful reactive oxygen species (ROS). Here we show a
