Unravelling the age of fine roots of temperate and boreal forests
Nature Communications, 2018 Fine roots support the water and nutrient demands of plants and supply carbon to soils. Quantifying turnover times of fine roots is crucial for modeling soil organic matter dynamics and constraining carbon cycle–climate feedbacks.

Does the Second Caustic Ring of Dark Matter Cause the Monoceros Ring of Stars ? [PDF]
, 2007 Caustic rings of dark matter were predicted to exist in the plane of the Galaxy at radii $a_n \simeq 40 {\rm kpc}/n$ for $n = 1,2,3 ..$. The recently discovered Monoceros Ring of stars is located near the $n=2$ caustic, prompting us to consider a ...

Using eye lens diameter as age indicator of young Lithognathus mormyrus and Diplodus vulgaris [PDF]
, 2000 Eye lens diameter was analyzed in two sparid fish species, Lithognathus mormyrus and Diplodus vulgaris, in order to determine the possibility of using these data for age determination.
