A Novel Image‐Based Approach for Analyzing Neutrophil Chemotaxis Using a Boyden Chamber Assay

open access: yesCurrent Protocols, Volume 5, Issue 11, November 2025.
Abstract Chemotaxis is a fundamental biological process in which cells such as leukocytes migrate directionally from one site to another in response to a chemical gradient. This process of cellular migration is critical for execution of appropriate physiological responses to inflammation, as observed during immune defense and wound healing responses ...

Across the edge: Spatial segregation drives community structure in tri‐trophic multilayer networks at a forest–grassland edge

open access: yesJournal of Animal Ecology, Volume 94, Issue 11, Page 2205-2219, November 2025.
This study reveals how forest–grassland edges act as ecological barriers that shape tri‐trophic interaction networks. Using multilayer network theory, it uncovers how species influence and biodiversity patterns emerge across spatial layers, offering novel insights into edge‐driven community assembly and conservation in fire‐prone mosaics.

On the Identifiability of Genetic Parameters for Growth in Mice With a Massively Deep Pedigree

open access: yesJournal of Animal Breeding and Genetics, Volume 142, Issue 6, Page 706-717, November 2025.
ABSTRACT In models with direct and maternal genetic effects, structural features of the data are a potential source of bias and low accuracy of estimates for genetic covariance parameters. One of the well‐known reasons for such poor practical identifiability is the lack of dams with own observations.
