Flower Color as Predictor for Nectar Reward Quantity in an Alpine Flower Community [PDF]

open access: goldFrontiers in Ecology and Evolution, 2021
Entomophilous plants have evolved colorful floral displays to attract flower visitors to achieve pollination. Although many insects possess innate preferences for certain colors, the underlying proximate and ultimate causes for this behavior are still ...

Not Too Warm, Not Too Cold: Thermal Treatments to Slightly Warmer or Colder Conditions from Mother’s Origin Can Enhance Performance of Montane Butterfly Larvae

open access: yesBiology, 2022
Climate change alters organismal performance via shifts in temperature. However, we know little about the relative fitness impacts of climate variability and how cold-adapted ectotherms mediate these effects.

The engineered CD80 variant fusion therapeutic davoceticept combines checkpoint antagonism with conditional CD28 costimulation for anti-tumor immunity

open access: yesNature Communications, 2022
CD28 costimulatory signalling can be suppressed by immune checkpoints, such as CTLA-4 and PD-1. Here the authors describe the design of the fusion therapeutic davoceticept (ALPN-202), based on a variant CD80 extracellular domain engineered to bind PD-L1 ...

Genetic analysis of the frozen microbiome at 7900 m a.s.l., on the South Col of Sagarmatha (Mount Everest)

open access: yesArctic, Antarctic, and Alpine Research, 2023
Microbial communities in alpine environments >7,500 m.a.s.l. have not been well studied using modern cultivation-independent sequencing approaches due to the challenges and danger associated with reaching such high elevations.

Functional and Structural Responses of Arctic and Alpine Soil Prokaryotic and Fungal Communities Under Freeze-Thaw Cycles of Different Frequencies

open access: yesFrontiers in Microbiology, 2020
Ongoing climate change involves increasing snow scarcity, which results in more frequent freeze-thaw cycles (FTCs) in polar and alpine soils. Although repeated FTCs have been shown to alter the structure and functions of soil microbial communities, a ...
