Anthropogenic Impacts on Bark and Ambrosia Beetle Assemblages in Tropical Montane Forest in Northern Borneo

open access: yesInsects
Anthropogenic disturbances, such as forest conversion, have a profound impact on species distributions and biodiversity in tropical forests. This study aimed to determine the diversity and distribution of bark and ambrosia beetles (Curculionidae ...

The compared costs of domination, location-domination and identification

open access: yesDiscussiones Mathematicae Graph Theory, 2020
Let \(G\) be a graph and \(\{u\in V(G):d_G(u,v)\leq r\}\) is a ball of radius \(r\in\mathbb{N}\) centered at \(v\in V(G)\) and denoted by \(B_r(v)\). We say that \(x,y\in V(G)\) are \(r\)-twins if \(B_r(x)=B_r(y)\). A set \(D_1\subseteq V(G)\) is an \(r\)-dominating code of \(G\) if \(D_1\cap B_r(v)\neq\emptyset\) for every \(v\in V(G)\).

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

open access: yesFEBS 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 ...

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

open access: yesFEBS 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 ...

Loss of ecologically important genetic variation in late generation hybrids reveals links between adaptation and speciation

open access: yesEvolution Letters, 2020
Adaptation to contrasting environments occurs when advantageous alleles accumulate in each population, but it remains largely unknown whether these same advantageous alleles create genetic incompatibilities that can cause intrinsic reproductive isolation

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

In situ imagery unravels resources exploitation strategies among ant communities in a tropical agrosystem

open access: yesEcosphere
Ants are one of the most widespread groups of insects, but the mechanisms allowing them to coexist despite having similar nutritional needs remain unclear.
