Frequency and Density Associated Grouping Patterns of Male Roosevelt Elk

open access: yesFrontiers in Ecology and Evolution, 2020
Group-size variation has been examined within a framework of costs and benefits to ecological factors such as food limitations and risks from predators.

A two‐sex integrated population model reveals intersexual differences in life history strategies in Cooper's hawks

open access: yesEcosphere, 2023
Integrated population models (IPMs) combine population counts with demographic data to improve the precision of estimates of population size and demographic rates.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Spatially explicit analyses unveil density dependence

open access: yes, 2004
Density-dependent processes are fundamental in the understanding of species population dynamics. Whereas the benefits of considering the spatial dimension in population biology are widely acknowledged, the implications of doing so for the statistical ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Individual differences, density dependence and offspring birth traits in a population of red deer [PDF]

open access: yes, 2008
Variation between individuals is an essential component of natural selection and evolutionary change, but it is only recently that the consequences of persistent differences between individuals on population dynamics have been considered.

Density dependence and phenological mismatch: consequences for growth and survival of sub-arctic nesting Canada Geese

open access: yesAvian Conservation and Ecology, 2015
The extent to which species are plastic in the timing of their reproductive events relative to phenology suggests how climate change might affect their demography.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.
