Latitudinal insolation gradients throughout the Holocene II: High frequency variations
(Elsevier, 2020-10)
In a first paper, we presented an in-depth discussion and a computational method (free of the calendar problem) to reckon any kind of latitudinal insolation gradients, LIGs, throughout the Holocene and up to CE 3000. One ...

Herbivory and eutrophication mediate grassland plant nutrient responses across a global climatic gradient
(Ecological Society of America, 2018-03-31)
Plant stoichiometry, the relative concentration of elements, is a key regulator of ecosystem functioning and is also being altered by human activities. In this paper we sought to understand the global drivers of plant ...
Optimal photosynthetic use of light by tropical tree crowns achieved by adjustment of individual leaf angles and nitrogen content
Background and Aims Theory for optimal allocation of foliar nitrogen (ONA) predicts that both nitrogen concentration and photosynthetic capacity will scale linearly with gradients of insolation within plant canopies. ONA ...
Light and the outcome of the critically ill: an observational cohort study
(2012)
Abstract
Introduction
Light before and during acute illness has been associated with both benefit and harm in animal models and small human studies. Our objective was to ...
A 22,000-year record of monsoonal precipitation from northern chile's atacama desert
(American Association for the Advancement of Science, 2000)
Fossil rodent middens and wetland deposits from the central Atacama Desert (22°to 24°S) indicate increasing summer precipitation, grass cover, and groundwater levels from 16.2 to 10.5 calendar kiloyears before present (ky ...
Climatic controls of Holocene fire patterns in southern South America
(2007)
Holocene fire-climate-vegetation linkages are mostly understood at individual sites by comparing charcoal and pollen records with other paleoenvironmental proxy and model simulations. This scale of reconstruction often ...
