Nonstructural carbohydrates predict survival in saplings of temperate trees under carbon stress
Functional Ecology, Volume 36, Issue 11, Page 2806-2818, November 2022., 2022 Read the free Plain Language Summary for this article on the Journal blog. Abstract Nonstructural carbohydrates (NSCs) mediate plant survival when the plant's carbon (C) balance is negative, suggesting that NSCs could predict plant survival under C stress.

Dendocarbin A: a sesquiterpene lactone fromDrimys winteri
Acta Crystallographica Section C Structural Chemistry, 2014 The natural compound dendocarbin A, C15H22O3, is a sesquiterpene lactone isolated for the first time fromDrimys winterifor var chilensis. The compound crystallizes in the orthorhombic space groupP212121and its X-ray crystal structure confirmed theS/Rcharacter of the chiral centres at C-5/C-10 and C-9/C-11, respectively. The α-OH group at C-11 was found

Ecology and Evolution, Volume 12, Issue 10, October 2022., 2022 The results of this study show that the inter‐annual dependence of Austral parakeets on native habitats is influenced by the masting seed production strategy of Araucaria, a key species in the northern Patagonian Andes. Currently, this dependence seems to be largely modulated by disturbing factors promoting a feeding shift to exotic plants in anthropic

Journal of Ecology, Volume 110, Issue 9, Page 2219-2231, September 2022., 2022 Litter mixing did not have strong effects on decomposition rates across the studied climatic gradient overall, and the direction and intensity of the mixture effects were context dependent. The effects were stronger and more negative in the dryer ecosystems.

Unraveling Evolution in the Homoploid Complex of <i>Baccharis</i> L. in Chile. [PDF]
Ecol EvolGenotyping‐by‐Sequencing (GBS) was used to characterize hybrids originating from the species B. macraei and B. linearis and identifying the substructure of the hybrid complex. ABSTRACT Baccharis × intermedia (Asteraceae), found in central Chile, is a naturally occurring hybrid derived from the parent species B. macraei and B. linearis. It represents an

Feather Microbiota Landscapes: Biogeography and Phenology Shape Feather Microbiota Traits in a Migratory Seabird in a Subantarctic Ecosystem. [PDF]
Mol EcolABSTRACT It is known that phenological changes (i.e., behavioural and sometimes morphological and physiological traits that repeat annually) influence the wildlife gut microbiota. However, it remains largely unknown to what extent geographic variation could modulate the effect that phenology has on wildlife microbiota.

Influence of forest soil on biodegradation of Drimys winteri by Ganoderma australe
International Biodeterioration & Biodegradation, 2006 Abstract The basidiomycete Ganoderma australe is responsible for a unique field biodegradation process resulting in completely white-rotted logs known as “palo podrido” in southern Chile. Although the field formation of “palo podrido” has been evaluated, attempts to reproduce this selective delignification in vitro have failed.

Effect of different drying conditions on volatile compounds of Canelo pepper (Drimys winteri)
Journal of Phytology, 2020 Canelo pepper is produced with the fruit of Drimys winteri (Winteraceae family). Driven by gourmet cuisine, this product is becoming increasingly in demand. The aim of this work was to study the effect of two drying conditions on the composition of the volatile compounds of Canelo pepper from Ushuaia forests (Argentina).

Crude extracts of Drimys winteri bark to inhibit growth of Gaeumannomyces graminis var. tritici [PDF]
Chilean journal of agricultural research, 2011 The aim of this study was to assess the effect of Drimys winteri J.R. Forst. & G. Forst. bark and its extracts, obtained sequentially with n-hexane, acetone, and methanol, against Gaeumannomyces graminis var. tritici (Ggt). Ground bark of D. winteri was mixed with potato dextrose agar growth media at concentrations of 250, 500, 1000, 2000, and 4000 mg ...
