Enhancement of immune checkpoint inhibitor efficacy by DHX58+ SELL+ T cells in advanced gastric cancer

VIEW, EarlyView.
We created a coculture system using patient‐derived organoids (PDOs) and tumor‐infiltrating lymphocytes (TILs) that mimics important interactions between PDOs and TILs in the presence of various ICIs. Our findings reveal that CD62L+ T cells, activated by CD44+ cancer stem cells (CSCs), facilitate tumor regression in samples sensitive to ICIs, which is ...

Merocoenoses of cambioxylophagous insect fauna of Norway spruce (Picea abies [L.] Karst.) with focus on bark beetles (Coleoptera: Scolytidae) and types of tree damage in different gradation conditions

Journal of Forest Science, 2010
Research on merocoenoses of cambioxylophagous insect fauna of Norway spruce (Picea abies [L.] Karst.) was carried out in spruce stands of different age in the area with an endemic population (Moravian-Silesian Beskids, Czech Republic) and in the area ...

Development of optimized methods for unbiased dusky grouse population monitoring using real and simulated data

Wildlife Biology, EarlyView.
Rigorous state‐wide monitoring programs are lacking for dusky grouse Dendragapus obscurus, a North American species of forest grouse with relatively low detectability that is found in coniferous and mountainous areas in the western United States and Canada.

Isolation, Expression Profiling, and Regulation via Host Allelochemicals of 16 Glutathione S-Transferases in the Chinese White Pine Beetle, Dendroctonus armandi

Frontiers in Physiology, 2020
The Chinese white pine beetle (Dendroctonus armandi) is undoubtedly one of the most important pests causing ecological damage in the Qinling Mountains. When bark beetles invade conifers, they must overcome host tree defenses, including primary resistance

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Decreasing water availability reduces productivity in Swiss forests along an altitudinal gradient

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests are one of the most important terrestrial carbon sinks, but are increasingly under pressure due to drought, heat and the occurrence of extreme events. There are opposing longer term trends for European forest growth reported, and severe drought and disturbance ...

Ecological and social factors lead to variation in parental care between sexes in a burying beetle

Insect Science, EarlyView.
We experimentally investigated the effects of ecological (resource availability and interspecific competition) and social factors (intraspecific competition) on parental care and reproductive success in the burying beetle Nicrophorus vespilloides. Our results showed that males and females adjust their parental care based on resource availability and ...

An Overview of Genes From Cyberlindnera americana, a Symbiont Yeast Isolated From the Gut of the Bark Beetle Dendroctonus rhizophagus (Curculionidae: Scolytinae), Involved in the Detoxification Process Using Genome and Transcriptome Data

Frontiers in Microbiology, 2019
Bark beetles from Dendroctonus genus promote ecological succession and nutrient cycling in coniferous forests. However, they can trigger outbreaks leading to important economic losses in the forest industry.

Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

Integrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Special delivery: A hardwood‐killing bark beetle vectors its unusual symbiote among host trees

Ecosphere
In mutualistic symbioses with fungi, herbivorous insects such as bark beetles (Coleoptera: Curculionidae: Scolytinae) gain access to resources that are unavailable in the absence of fungal mutualists, while fungi benefit from insect‐vectored dispersal ...
