A comparison of thermal drones and camera trap population estimates for Sitka black‐tailed deer in Alaska

open access: yesWildlife Biology, EarlyView.
One of the most difficult challenges for wildlife managers is reliably estimating wildlife populations. Camera traps combined with spatial capture–recapture (SCR) models are a popular tool for population estimation. They have limitations, however, including long data processing times.

Pteridines, LXXXVIII. Oxidations and Reactions of 2- and 4-Thiolumazine Derivatives. Synthesis and Properties of Pteridine-Sulfinates and -sulfonates

open access: yesPteridines, 1989
Selective oxidations of 2-thiolumazines (10-12) by H20 2 and KMn04 respectively in basic medium led to the corresponding stable pteridin-4-one-2-sulfinates (13-15) and -sulfonates (16-18), which can be isolated in the form of their potassium salts.

Relationships Between European Wildcats and Domestic Cats in an Area of Sympatry: Exploring Key Conservation Questions on Hybridization and Disease Transmission

open access: yesAnimal Conservation, EarlyView.
We have found evidence of behavioural barriers for both hybridization and disease transmission between European wildcats and domestic cats. This includes hierarchical interspecies exclusion enforced by wildcats, as well as sexual selection exerted by wildcat females.

Factors Associated With Long‐Term Survivors With Epidermal Growth Factor Receptor Positive Non‐Small Cell Lung Cancer Treated With First or Second‐Generation Tyrosine Kinase Inhibitors: A Canadian Multi‐Center Cohort

open access: yesAsia-Pacific Journal of Clinical Oncology, EarlyView.
In a multi‐center Canadian cohort of 577 patients with advanced epidermal growth factor receptor‐mutated non‐small cell lung cancer treated with first/second‐generation TKIs, Asian ancestry and female sex predicted longer survival, while the L858R mutation predicted shorter survival.
