Modelos de crecimiento diamétrico para Nothofagus obliqua [PDF]
SUMMARY Non-linear, Bertalanffy-Richards-type models of diameter growth were developed for Nothofagus obliqua and fitted for different social tree strata using the diameter annual increment (id) and diameter at breast height (dap). The biological and statistical analyses were conducted from two different sources; an independent data set taken mainly ...

Political Cycles, Electricity Policy, and Mexico's Economy
ABSTRACT Electricity reform in Mexico should stimulate economic growth, improve energy efficiency, and reduce greenhouse gas emissions. This article evaluates the successes and failures of reform and draws lessons across political cycles by analyzing changes in political dynamics—often tied to policy reversals—and the legal framework during the pro ...

European mistletoe shares a similar demographic strategy with non‐parasitic plants
European mistletoe (Viscum album) does not have a distinct demographic strategy from non‐parasitic plants, as quantified by time‐based life history traits. We found that mistletoe vital rates were driven by mistletoe size and position in the host tree.

Beyond species means – the intraspecific contribution to global wood density variation
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from
