General patterns of forest dynamics and productivity in the Andes Mountains are poorly characterized.Here we present the first large-scale study of Andean Dresses forest dynamics using a set of 63 permanent forest plots assembled over the past two decades.In the North-Central Andes tree turnover (mortality and recruitment) and tree growth declined
Marsupial sex chromosomes break the rule that recombination during first meiotic prophase is necessary to ensure reductional segregation during first meiotic division.It is widely accepted that in marsupials X and Y chromosomes do not share homologous regions, and during male first meiotic prophase the synaptonemal complex is absent between them.Al

A key component in understanding plant-insect interactions is the nature of host defenses.Research on defense traits among Pinus species has focused on specialized metabolites and axial resin ducts, Mugs but the role of lignin in defense within diverse systems is unclear.We investigated lignin levels in the outer bark and phloem of P.longaeva, P.ba
