Moisture variability in northeast Tibet following the middle Miocene Climate transition

open access: yesCommunications Earth & Environment
After the middle Miocene Climate transition, global cooling caused substantial hydrological changes in East Asia. Today, many lines of evidence indicate that inland East Asia experienced persistent aridification after the middle Miocene Climate ...

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China

open access: yesGeological Journal, EarlyView.
Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

Thermochronologic Constraints on the Extensional History of the Ibex Hills, Southeastern Black Mountains, Death Valley, California

open access: yesGeological Journal, EarlyView.
A. Modeled T‐t paths for samples in the northern Ibex Hills, showing steady cooling throughout much of the Cenozoic, until rapid Miocene cooling. B. Weighted mean paths for each sample in this study. Note that all show a rapid cooling event at or just after 10 Ma, which is interpreted to represent exhumation as a result of regional extenstion ...

Nutrition Status of Trees on Spoil Heaps After Coal Mining Can Be Inferred From Seasonal Dynamics of Foliar Nutrient Concentrations

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT A stable vegetation cover on given habitat conditions can be one of the possible requirements for post‐mining sites, as it can prevent erosion and dustiness of these anthropogenic surfaces and bring several practical future benefits, such as biomass production and microclimate improvement.

Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

open access: yesTAXON, EarlyView.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species

Calappa praelata Lőrenthey in Lőrenthey & Beurlen, 1929 (Decapoda, Brachyura, Calappidae) from the Middle Miocene of Tresnuraghes (Oristano, Sardegna, Italy)

open access: yesNatural History Sciences, 2012
We report Calappa praelata Lőrenthey in Lőrenthey & Beurlen, 1929 (Calappidae De Haan, 1833), based upon one single carapace, three-dimensionally preserved, from the Middle Miocene of Tresnuraghes (Oristano, Sardegna, Italy).

Sedimentation and subsidence history of the Lomonosov Ridge [PDF]

open access: yes, 2006
During the first scientific ocean drilling expedition to the Arctic Ocean (Arctic Coring Expedition [ACEX]; Integrated Ocean Drilling Program Expedition 302), four sites were drilled and cored atop the central part of the Lomonosov Ridge in the Arctic ...

Carya nux‐taurinensis comb. nov., a fossil‐species incorporating Carya globosa (Juglandaceae)

open access: yesTAXON, 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 ...
