Diversity–Elevation Relationships of Vascular Plants in Austral Temperate Ecosystems Are Strata Dependent [PDF]
We investigated diversity patterns of vascular plants of overstorey and understorey vegetation separately per stratum and the influence of anthropogenic disturbances along two elevational transects with contrasting slope aspects in a temperate rainforest and alpine scrub in southern Chile.

Low population genetic structure in five Chilean Nothofagus species and high fluctuating asymmetry in Nothofagus pumilio x N. antarctica putative hybrids [PDF]
Background Following historic natural disturbances, interspecific hybridization has been documented between several Nothofagus species in Chilean forests.

Neogene plant macrofossils from West Antarctica reveal persistence of Nothofagaceae forests into the early Miocene [PDF]
The extinction of woody vegetation in Antarctica remains difficult to constrain due to its fragmented macrofossil record. Despite its long-standing polar position, Antarctica hosted extensive vegetation throughout the Paleogene.

Feather Microbiota Landscapes: Biogeography and Phenology Shape Feather Microbiota Traits in a Migratory Seabird in a Subantarctic Ecosystem [PDF]
ABSTRACT 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.

Trophic facilitation in forest restoration: Can Nothofagus trees use ectomycorrhizal fungi of the pioneer shrub Leptospermum? [PDF]
The benefits of plant‐to‐plant facilitation in ecological restoration are well recognized, yet the potential for indirect trophic facilitation remains understudied.

Ectomycorrhizal fungi and the nitrogen economy of Nothofagus in southern Patagonia [PDF]
Subantarctic Nothofagus forests are the southernmost forests in the world, with negligible atmospheric nitrogen (N) deposition. Most paradigms about the role of ectomycorrhizal (ECM) fungi in N cycling and plant N uptake at high latitudes have been ...

Phylogenetic relationships and time-calibration of the South American fossil and extant species of southern beeches (Nothofagus) [PDF]
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

Nothofagus and the associated palynoflora from the Late Cretaceous of Vega Island, Antarctic Peninsula [PDF]
Nothofagaceae fossil leaves and an associated palynoflora from Late Cretaceous sediments of Vega Island, eastern Antarctic Peninsula, are presented. The leaves are described as Nothofagus sp.

Net photosynthetic rate (A) and stomatal conductance (gs) of leaves of Nothofagus pumilio and N. an-tarctica seedlings were measured at different photosynthetic photon flux densities (PPFDs, 20, 150, 250, 500, 750, 1,000, 1,500 and 2,200 μmol/m2/s) and ...
