Nectar Robbery by Native and Invasive Bumblebees Reduces Floral Rewards but Not Seed Production in <i>Desfontainia fulgens</i>. [PDF]
Ecol EvolWe evaluated nectar robbery by native and invasive bumblebees in the hummingbird‐pollinated shrub Desfontainia fulgens in southern Chile. Nectar robbery strongly reduced nectar standing crop and altered floral visitation patterns, but these proximate effects did not translate into reduced seed production under natural pollination conditions.

Pre-Courtship Behavior of Proholopterus chilensis (Coleoptera: Cerambycidae) in a Nothofagus obliqua (Nothofagaceae) Forest [PDF]
InsectsThe pre-courtship behavior of Proholopterus chilensis on Nothofagus obliqua trees was recorded for the first time, documenting a putative female “calling” behavior and the consequent male “oriented search,” enabling the description of behavioral units ...

Fires in rainforests: Quantifying litter bed flammability of cool temperate rainforests in eastern Australia. [PDF]
Am J BotAbstract Premise Rainforests are usually too wet to burn, acting as natural barriers to fire spread and as refuges for biodiversity. However, climate change is increasing the risk of fire incursion into rainforests. Our capacity to manage these impacts is hindered by limited research on rainforest flammability.

New Species and Records of Nothofagicola n. sp. (Eriophyoidea, Phytoptidae) from Chile and Updated Key to the World Genera of the Tribe Sierraphytoptini Keifer 1944 [PDF]
AnimalsThe monophyletic lineage Phytoptidae s. str. (Acariformes, Eriophyoidea) comprises ~75 described species in 17 genera associated with angiosperms. Since the last keys to the world genera of Eriophyoidea were published in 2003, five new phytoptid genera ...

Fungal diversity in canopy soil of silver beech, Nothofagus menziesii (Nothofagaceae).
PLoS ONE, 2020 Adventitious roots in canopy soils associated with silver beech (Nothofagus menziesii Hook.f. (Nothofagaceae)) form ectomycorrhizal associations. We investigated the extent to which canopy ectomycorrhizal communities contribute to overall diversity of ...

Testing key tenets of pyro-ecophysiology: Indicators of drought response in relation to shoot flammability. [PDF]
Am J BotAbstract Premise Relationships between flammability and drought tolerance influence vegetation dynamics during fires. A goal of the emerging subdiscipline of pyro‐ecophysiology is to identify ecophysiological traits that determine live fuel flammability, but empirical studies of these relationships are rare.

Chromosome number of two Chilean species of Nothofagus (Nothofagaceae) [PDF]
Gayana - Botanica, 2014 Se documenta un numero cromosomico 2n = 26 (x = 13) para Nothofagus dombeyi (Mirb.) Oerst. y N. glauca (Phil.) Krasser, el cual es similar al descrito previamente para otras especies del genero. Se incrementan a 13 las especies de Nothofagus con numero cromosomico conocido, existiendo dos numeros basicos (x = 13, 14).

Ectomycorrhizal fungi and the nitrogen economy of Nothofagus in southern Patagonia [PDF]
Ecology and EvolutionSubantarctic 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 ...
