Native vegetation of the southern forests : south-east highlands, Australian alps, south-west Slopes, and SE Corner bioregions [PDF]
, 2013 The Southern Forests study area covers an area of about six million hectares of south-eastern New South Wales, south of Oberon and Kiama and east of Albury and Boorowa (latitude 33° 02’–37 ° 06’ S; longitude 146° 56’ – 147° 06’ E).

Carya nux‐taurinensis comb. nov., a fossil‐species incorporating Carya globosa (Juglandaceae)
TAXON, EarlyView.Abstract The type material of the almost forgotten fossil‐species Juglans nux‐taurinensis is newly analysed, a lectotype is designated, and new conspecific material detected at the Italian type locality La Morra is described. We show that Juglans nux‐taurinensis must be reassigned to Carya because the locule cast of the nutshell shows two inner ...

Archaeometry, EarlyView.Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Archaeometry, EarlyView.ABSTRACT Since 2000, archaeological excavations have brought to light the sanctuary of Athena in Castro (Apulia, Italy), including terracotta roofs dated between the 6th and 4th centuries bce. Based on their morphological and stylistic features, it is suggested that the terracotta items were manufactured in the Greek colony of Taras (modern Taranto ...

Early Holocene jökulhlaup chronology and deglaciation dynamics in central Iceland
Boreas, EarlyView.Glacial lake outburst floods (jökulhlaups) have occurred throughout the Quaternary in glaciated regions worldwide. Reconstructing flood chronology yields insight into deglaciation processes, environmental change and the role of extreme events in landscape evolution.

Boreas, EarlyView.This study examines the distribution and morphology of lakes under the Laurentide Ice Sheet (LIS) to investigate relationships with ice flow velocity, bedrock and basal thermal regime. Palaeo‐ice streams and lobes were important components of the LIS, and properties of lakes in those regions are quantified at high resolution.
