A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

open access: yesCladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Capture Probability and Effects of Bait Type on Learning Behavior in an Unexploited Population of Northern Pike (Esox lucius)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Changes in angling response were studied over a period of three years in a natural, previously unfished population of northern pike. Standardized angling sessions took place during two weeks in spring and autumn with three bait types: bright‐ and natural‐colored soft plastic baits and a dead baitfish.

Characterisation of human hair follicle development

open access: yesJournal of Anatomy, EarlyView.
Schematic of hair follicle development in human skin. Hair follicle primordia of similar sizes, but different densities, are laid out across the skin. The distinction between terminal and vellus hair sites is not obvious at early stages of hair follicle development.
