Araucaria araucana: Monkey Puzzle Tree

EDIS, 2003
Monkey-Puzzletree is a large, bizarre evergreen, 60 to 70 feet tall and 30 to 35 feet wide, which forms a loose, see-through, pyramidal shape with a straight trunk. The tree is so open in habit you could almost look at it and not see it.

A cost-effective DNA extraction protocol for long-read sequencing in non-model plants. [PDF]

Appl Plant Sci
Abstract Premise Third‐generation sequencing has revolutionized genomics, enabling in‐depth analysis of genome sequence, structure, and epigenetic features. Yet, extracting high‐quality DNA for long‐read sequencing remains a bottleneck—particularly in non‐model plants, such as mature trees growing in natural environments, which often contain abundant ...

Altered fire regimes modify lizard communities in globally endangered Araucaria forests of the southern Andes [PDF]

Scientific Reports, 2021
Wildfire regimes are being altered in ecosystems worldwide. The density of reptiles responds to fires and changes to habitat structure. Some of the most vulnerable ecosystems to human-increased fire frequency are old-growth Araucaria araucana forests of ...

A Mosaic of Future Maladaptation Predicted for the Widespread Tree <i>Nothofagus pumilio</i>. [PDF]

Evol Appl
ABSTRACT Nothofagus pumilio, or lenga beech, is a widespread and locally‐adapted tree species endemic to South America's Patagonia region. Its diverse populations span a 2000‐km‐long range in the Andes Mountains, which is already experiencing adverse effects from climate change.

First wild boar density data from Araucaria forest in Patagonian Andes [PDF]

PeerJ
As Sus scrofa is an invasive species in South America, it may have a significant impact on biodiversity. Evaluating this threat requires reliable data, and population density can serve as a critical measure.

Listening Deeply to Indigenous People: A Collaborative Perspective and Reflection Between a Mapuche Machi and Ecologists. [PDF]

Ecol Evol
Two‐eyed seeing offers a way to see with both Indigenous Traditional Ecological Knowledge and Western ecological sciences. In this collaborative perspective piece between ecologists and a Mapuche spiritual authority (a Machi), we interweave lived experiences and ecological evidence to present the alarming social‐ecological devastation and conflict in ...

Native trees are related to advanced bird breeding phenology and increased reproductive success along an urban gradient. [PDF]

Ecology
Abstract Urban areas are altered from natural landscapes in several ways that can impact wildlife. Birds are widespread in urban areas, and it is well documented that there are phenotypic differences between urban and non‐urban conspecifics. However, little is known about which characteristics of the urban environment are driving differences. We used 9

The Cinderella tree, <i>Quillaja saponaria</i> - A soap story. [PDF]

Plants People Planet
Our current understanding of plants has been shaped by the entwining of different cultures. The Chilean soapbark tree, traditionally valued as a source of natural soap, was shown by serendipitous research in France in the 1900s to produce compounds that can boost the immune response to vaccines.

Intraspecific variation in masting across climate gradients is inconsistent with the environmental stress hypothesis. [PDF]

Ecology
Abstract Year‐to‐year variation in seed crop size (i.e., masting) varies strongly among populations of the same species. Understanding what causes this variation is vital, as masting affects the ability of tree species to regenerate and determines the population dynamics of a wide variety of animals.
