Detecting and attributing climate change effects on vegetation: Australia as a test case
Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.

The use of chloroplast genome sequences to solve phylogenetic incongruences in Polystachya Hook (Orchidaceae Juss) [PDF]
Background: Current evidence suggests that for more robust estimates of species tree and divergence times, several unlinked genes are required. However, most phylogenetic trees for non-model organisms are based on single sequences or just a few regions ...

A Mosaic of Future Maladaptation Predicted for the Widespread Tree Nothofagus pumilio
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.

ZOOFITOFAGOS EN NOTHOFAGUS CHILENOS
Nematodes and insects have been the only zoophytophagous groups that have been reported in the literature living on Nothofagus in Chile. According to the area covered by Nothofagus and the type of plant that it represents, (apparent) the number of phytophagous insects living on this genus was estimated in 125.

Low temperature responses of Nothofagus dombeyi and Nothofagus nitida, two evergreen species from south central Chile [PDF]
Nothofagus dombeyi (Mirb.) Blume and Nothofagus nitida (Phil.) Krasser are closely related evergreen trees native to south central Chile. Nothofagus dombeyi is a pioneer in habitats subject to high daytime irradiances and nighttime freezing temperatures and has a wider altitudinal and latitudinal distribution than N. nitida, which is restricted to more

Nuevos registros de Ceratopogonidae (Diptera) para Argentina y Chile [PDF]
New records are provided for 22 species of biting midges (Diptera: Ceratopogonidae) from Argentina and Chile, 12 belonging to Forcipomyia Meigen, two to Atrichopogon Kieffer and Culicoides Latreille, and one to Leptoconops Skuse, Dasyhelea Kieffer ...

We hypothesized that litter decomposition (H1) and litter quality (H2) increase with increasing soil humidity, therefore litter from the wetter sites to have the highest litter quality and decompose fastest in each site, and fastest on the wet end of the gradient (H3).

A comparison of the moss floras of Chile and New Zealand [PDF]
Chile and New Zealand share a common stock of 181 species of mosses in 94 genera and 34 families. This number counts for 23.3% of the Chilean and 34.6% of the New Zealand moss flora.

Are Hibernators Toast? Global Climate Change and Prolonged Seasonal Hibernation
This review examines how global climate change impacts mammalian hibernators, emphasizing physiological, ecological and phenological aspects. Many hibernating species already inhabit extreme environments, thus are at risk as climate variability intensifies.

Weak global trade‐off between frost and drought resistance in trees
Summary Drought and frost stresses play important roles in determining species distributions, especially at range margins. Understanding how stress resistance traits interact to determine vulnerability to climate change is critical. We developed a large global database of published and new measurements of drought resistance (xylem embolism resistance ...
