Biogeochemical asymmetry and the diversification of tropical rain forests in Borneo: The endmember hypothesis

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mixed dipterocarp lowland tropical rain forests on Oxisols and Ultisols and heath forests on Spodosols are considered distinct vegetation types in Borneo. Here we present the endmember hypothesis of ecosystem diversification, which describes a continuum of forest ...

Vδ2 T-cell engagers bivalent for Vδ2-TCR binding provide anti-tumor immunity and support robust Vγ9Vδ2 T-cell expansion

Frontiers in Oncology
BackgroundVγ9Vδ2 T-cells are antitumor immune effector cells that can detect metabolic dysregulation in cancer cells through phosphoantigen-induced conformational changes in the butyrophilin (BTN) 2A1/3A1 complex.

Leaf trichomes can alleviate water deficit stress and maintain diurnal photosynthesis by increasing leaf wetness and water absorption in Metrosideros polymorpha

Plant Species Biology, EarlyView.
Leaf trichomes are often considered a key trait contributing to drought tolerance by increasing leaf wetness and enhancing foliar water uptake. However, their function has not been examined across a wide range of environmental conditions. Our field observations and manipulation experiments on Metrosideros polymorph—a species with trichomes that vary ...

The Syntactic Status of Subject Clitics: A Problem from Venetan SE‐Constructions

Transactions of the Philological Society, EarlyView.
Abstract This article reopens the discussion on the syntax of subject clitics (SCLs) in Venetan dialects by providing a problematic piece of data and outlining its theoretical consequences. New evidence from se‐constructions in Alto Polesine Venetan (APV) shows that SCLs resist a unitary categorisation even within the same dialect group: in varieties ...

What can lithics tell us about hominin technology's ‘primordial soup’? An origin of stone knapping via the emulation of Mother Nature

Archaeometry, EarlyView.
Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)

Strangeness content of the nucleon in quasielastic neutrino-nucleus reactions

, 2007
We present a systematic study of the sensitivity of quasielastic neutrino-nucleus cross sections at intermediate energies to the strange quark sea of the nucleon. To this end, we investigate the impact of the weak strangeness form factors on the ratio of

Sourcing carnelian beads from the ancient Mesopotamian site of Kish, Iraq, 2450–2200 BCE: Stylistic, technological and geochemical approaches

Archaeometry, EarlyView.
Abstract Trade between Mesopotamia and the Indus Civilization is studied through the analysis of Early Dynastic III Period (2600–2350 BCE) carnelian beads from the site of Kish, Iraq. Morphological and technological features of the beads are compared with beads from the Indus region.

Fitosociología y sucesión en el volcán Paricutín (Michoacan, México)

Caldasia, 1997
A phytosociologic survey of the current vegetation covering the cone and lava flow of Paricutín Volcano was conducted 44 years after eruption. A cluster analysis of a total of 57 relevés was made using a two-way indicator species algorithm, Twinspan ...
