Channelization cascade in landscape evolution. [PDF]
Proc Natl Acad Sci U S A, 2020 The hierarchy of channel networks in landscapes displays features that are characteristic of nonequilibrium complex systems. Here we show that a sequence of increasingly complex ridge and valley networks is produced by a system of partial differential equations coupling landscape evolution dynamics with a specific catchment area equation. By means of a

Glassy dynamics of landscape evolution. [PDF]
Proc Natl Acad Sci U S A, 2018 Significance Soil is apparently solid as it moves downhill at glacial speeds, but can also liquefy from rain or earthquakes. This behavior is actually similar to that of glass, which creeps very slowly at low temperatures but becomes a liquid at higher temperatures.

The unexpectedly short Holocene Humid Period in Northern Arabia
Communications Earth & Environment, 2022 The Holocene Humid Period in Northern Arabia may only have lasted for less than 1000 years and was characterised by substantial regional climatic variability, according to a high-resolution multi-proxy varved lake record from Tayma, Saudi Arabia.

Tracing rate and extent of human-induced hypoxia during the last 200 years in the mesotrophic lake, Tiefer See (NE Germany) [PDF]
BiogeosciencesThe global spread of lake hypoxia, [O2] < 2 mg L−1, during the last 2 centuries has had a severe impact on ecological systems and sedimentation processes. While the occurrence of hypoxia was observed in many lakes, a detailed quantification of hypoxia

European tree-ring isotopes indicate unusual recent hydroclimate
Communications Earth & Environment, 2023 The 2015–2018 summer drought event was unprecedented in Western and Central Europe over the last 400 years, whereas multi-year droughts were more frequent during the Maunder Minimum, according to a hydroclimate reconstruction using tree-ring stable ...

ENSO flavors in a tree-ring δ18O record of Tectona grandis from Indonesia [PDF]
Climate of the Past, 2015 Indonesia's climate is dominated by the equatorial monsoon system, and has been linked to El Niño-Southern Oscillation (ENSO) events that often result in extensive droughts and floods over the Indonesian archipelago.

Winds From Massive Stars, And Implications for Supernovae and Gamma-Ray Bursts [PDF]
, 2006 We review the effects of winds from massive O and B stars on the surrounding medium over the various stages of stellar evolution. Furthermore we discuss some of the implications for SNe and GRB evolution within this wind-blown medium.Comment: 6 pages, 1 ...

Microfluidic landscapes for evolution [PDF]
Current Opinion in Chemical Biology, 2010 Evolution at its heart is an iterative algorithm composed of three steps: selection, amplification and mutagenesis. This algorithm can be applied to complex inputs such as populations of whole organisms and viruses, or mixtures of bare nucleic acids and proteins.
