Evolution in arid environments: the role of betalains, succulence, and medullary bundles
Overview of the study system. Summary The flowering plant clade Caryophyllales includes many succulent species that grow in drought conditions. Many Caryophyllales species also have betalain pigmentation and medullary bundles, both of which have been linked to stress tolerance, albeit with less precise functional characterisation.

Vertical restraints and competition policy [PDF]
This report considers the private and social welfare effects of vertical restraints - whereby contractual arrangements between suppliers (manufacturers) and distributors (retailers) extend beyond simple arms-length pricing.

Vertical integration, market foreclosure and quality investment [PDF]
Incentives to vertically integrate are studied in an industry where downstream firms are vertically differentiated. Vertical integration by one of the firms increases production costs for the rival.

Radial oxygen loss, rhizospheric methane oxidation and methane emissions from rice roots
Longitudinal variation in rice (Oryza sativa) root traits affecting the bidirectional diffusion of O2 and CH4. Summary Methane (CH4) produced in flooded paddy soils is emitted by passive diffusion, by ebullition and by diffusion through the rice (Oryza sativa) plant.

External structures at the nest‐site predict asymmetric architecture of nests in a mud‐building bird
In the animal kingdom, nests are essential structures and textbook examples of extended phenotypes. However, the relationship between builders, nest traits and the nest‐site remains poorly understood. We indirectly examine whether structures in the nest‐site influence nest‐building behaviour, specifically focusing on their effect on nest architecture ...

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes
Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...
