Diversity and Distributions, Volume 27, Issue 11, Page 2190-2203, November 2021., 2021 Abstract Aim In an increasingly anthropogenic world, species face multiple interacting threats. Habitat fragmentation and domestic dogs are two perturbations threatening terrestrial mammals globally. Our aim was to determine whether (a) the spatial use of domestic dogs increases with habitat destruction, and (b) domestic dogs and habitat destruction ...

Phylogenetic relationships and time-calibration of the South American fossil and extant species of southern beeches (Nothofagus) [PDF]
Acta Palaeontologica Polonica, 2018 The genus Nothofagus is considered as one of the most interesting plant genera, not only for the living species but also due to the fossil evidence distributed throughout the Southern Hemisphere. Early publications postulated a close relationship between

Disparate responses of above- and belowground properties to soil disturbance by an invasive mammal [PDF]
, 2014 Introduced mammalian herbivores can negatively affect ecosystem structure and function if they introduce a novel disturbance to an ecosystem. For example, belowground foraging herbivores that bioturbate the soil, may alter process rates and community ...

Insect antifeedant compounds from Nothofagus dombeyi and N. pumilio
Phytochemistry, 2004 A bioassay-guided purification of the extracts of Nothofagus dombeyi and N. pumilio leaves yielded several triterpenes and flavonoids including 2-O-acetylmaslinic acid, 3-O-acetyl 20,24,25-trihydroxydammarane, and 3,20,24,25-tetrahydroxydammarane as new natural products.

índice de sítio diamétrico: um método alternativo para estimar a qualidade do sítio em florestas de Nothofagus obliqua E N. alpina [PDF]
, 2016 The first step for constructing models of tree growth and yield is site quality assessment. To estimate this attribute, several methodologies are available in which site index (SI) is a standard one.

An ecophysiographic approach for Araucaria araucana regeneration management [PDF]
, 2012 Chilean temperate forests are dominated by Nothofagus and Araucaria araucana species. Despite A. araucana not being at imminent risk of extinction, its cultural value and the associated environmental services and landscape goods have an important role
