Running towards: Labour market incentives for runaway slaves in the British Cape Colony, 1830–1838

Asia‐Pacific Economic History Review, EarlyView.
Abstract Recent scholarship on slave escapes has increasingly emphasised economic motivation, but few studies have empirically investigated how market incentives influenced the decision‐making of enslaved individuals during transitions from coerced to wage labour.

Coerced labour patterns in the Cape Colony, c. 1806–1826

Asia‐Pacific Economic History Review, EarlyView.
Abstract Multiple forms of coerced labour co‐existed in the early 19th‐century Cape Colony. This study examines changes in coerced labour force composition. Using annual taxation and census records, we examine district‐ and household‐level changes in reported enslaved, Recaptured African and indigenous Khoesan labour.

Submerged geomorphic record of Quaternary palaeoshorelines: terraces and clinothems along a shelf‐edge in the Žirje Archipelago, Adriatic Sea

Boreas, EarlyView.
Numerous studies have shown that during the Quaternary there were substantial fluctuations in sea level in response to glacial–interglacial climate variability, reaching lowstand positions up to 134 m below the present sea level (b.s.l.). These fluctuations have had a strong influence on the morphology of shallow shelf seas, which preserve evidence of ...

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

Cladistics, 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 ...
