Temporal activity patterns of tourists and pumas Puma concolor in public areas in the Patagonia National Park, Chile

Wildlife Biology, EarlyView.
The presence of humans and large carnivores in shared landscapes presents unique challenges for wildlife conservation and management. This study explores the temporal activity patterns of tourists and pumas Puma concolor using camera traps to understand the potential for encounters between the two groups in Patagonia National Park, Chile.

An injector testbed based on a direct current gun and an interchangeable very high frequency gun for superconducting continuous‐wave free‐electron lasers

Journal of Synchrotron Radiation, EarlyView.
An injector testbed for continuous‐wave free‐electron lasers based on a direct current gun and an interchangeable very high frequency gun is under construction. Its physical design and performance have been studied carefully.The continuous‐wave free‐electron laser (CW‐FEL), based on superconducting radiofrequency (SRF) technology with an electron bunch

Coaxial helium electrospray for single‐particle imaging at X‐ray free electron lasers

Journal of Synchrotron Radiation, EarlyView.
This study presents the Coaxial Helium Electrospray (CHeES) technique, employing a 3D‐printed microfluidic coaxial nozzle to broaden the single particle imaging sample range at XFELs, enhancing sample conductivity support and reducing background noise.Single‐particle imaging at X‐ray free‐electron lasers relies on suitable sample injection of nanoscale

Spiroacetals and the rise of Campanula specialists: Receptor sensitivity to host‐specific floral scents

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Campanula flowers (Campanulaceae) are visited by generalist and specialist bees of different families. While generalists rely on common volatiles within the floral scent of Campanula, specialist Megachilidae mainly use unusual spiroacetals for host flower recognition ...

The role of insularity: Plants have few ornithophilous traits but are visited by morphologically more distinct hummingbirds in the Caribbean islands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Functional traits determine interactions between plants and pollinators, and to increase pollination efficiency, many plants have evolved traits to attract specific pollinator groups. However, biogeographical setting may influence trait evolution and biotic interactions.
