This is the first confirmed finding of Myrtaceidites eucalyptoides outside Australia.

Corner’s rules hold up across the growing season
The relationship between twig cross-sectional area and leaf surface area varied little over the course of the season.
A plant thought to aid Nothofagus may be out-competing it
The idea was simple, Proteaceae plants are experts at releasing phosphorus from soils, so planting them alongside Nothofagus should provide the beeches with natural fertilizer. The reality is more complex.

Hydraulic efficiency in two Patagonian trees keeps constant across a precipitation gradient
Generalist tree species growing across broad climatic gradients pose an intriguing question about how they can deal with such strong variations in climate. Studying the conductive system of trees may give a clue about...

How are monospecific stands of invasive trees formed? Spatio-temporal evidence from Douglas fir invasions
Invasive plant species can have many, often detrimental, impacts on native plant communities, especially when they reach high densities and form monospecific stands. Monospecific stands are common among invasive plant...

Early Palaeocene fossil flowers of Patagonia
Sixty-four million years ago, this elaborate flower grew in Patagonia, Argentina. The new species described by Jud et al. is named Lacinipetalum spectabilis Jud, Gandolfo, Iglesias & Wilf, gen. et. sp. nov. It was...

A new addition to the Patagonian Ceratopetalum five-winged fossil fruit family
Museomic approaches are employed in order to establish an evolutionary, palaeoecological, and biogeographic context for radially symmetrical, five-winged fossil fruits from the highly diverse early Eocene Laguna del...
Light partitioning in temperate rain forests
In the temperate rainforest of southern Chile, Fajardo and Siefert find that interspecific differences in the leaf mass per area (LMA) trait can explain the fine-scale partitioning of light availability gradients by...
Disturbance, density-dependent processes and genetic relatedness
Disturbances, dispersal and biotic interactions are three major drivers of the spatial distribution of genotypes within populations, the last of which has been less studied than the other two.
Defoliation, tree growth and storage of C and N
Although lenga beech trees, completely defoliated by caterpillars of Ormiscodes amphimone, do not die, they show reduced growth for at least 2 years.
Carbon budgets in deciduous and evergreen treeline species
A study of deciduous–evergreen mixed-species forests shows that both foliar types are sink-limited when faced with decreasing temperatures.
A new fossil taxon of Asteraceae
Barreda et al. describe Raiguenrayun cura gen. & sp. nov., an extinct Eocene taxon of the daisy family that might represent the ancestor of Mutisioideae–Carduoideae, based on an exceptionally well preserved...
Growth and carbon budgets in Nothofagus
Growth decline with age in trees is hypothesized to be an effect of carbon limitation. By assessing carbon reserves and isotopes at different ontogenetic stages in the deciduous broadleaf tree Nothofagus pumilio (lenga...
