An analysis of
northern ecosystems shows that the effects on plant growth of rising night-time
temperatures are opposite to those of increasing daytime temperatures — a
finding that has implications for carbon-cycle models.

Received 08 February 2013 Accepted 04 July 2013 Published online 04
September 2013
Catalysis of the
reduction of nitrogen to ammonia under mild conditions by a
tris(phosphine)borane-supported iron complex indicates that a single iron site
may be capable of stabilizing the various NxHyintermediates generated during
catalytic ammonia formation.
11. Asymmetric effects of daytime and night-time

Received 15 October 2012 Accepted 04 July 2013 Published online 04
September 2013
Correlations
between the maximum and minimum daily temperatures and a vegetation index in
the Northern Hemisphere suggest that asymmetric diurnal warming (faster warming
of the land surface during the night than during the day) produces several
different vegetation and carbon storage effects.

The global ocean
conveyor belt, a key element of climate change, carries heat, carbon and
various dissolved materials in the deep ocean. Here, the authors’ ocean model
simulations demonstrate that tide-induced mixing away from the sea bottom is
driving the Pacific branch of this conveyor belt.
26. Siberian larch forests and the ion content of thaw

Hitherto, Siberian
vegetation was not considered to cause the south-to-north ion content gradient
of thaw lakes. Herzschuh et al. propose that higher evapotranspiration
in larch forests compared with that in the tundra leads to local salt
accumulation in permafrost soils, which are transported as solutes to nearby
lakes.
