Revision and phylogenetics of the genus Paraulax Kieffer (Hymenoptera, Cynipidae) with biological notes and description of a new tribe, a new genus, and five new species
The gall wasp genus Paraulax (Hymenoptera, Cynipidae) associated with southern beeches (Nothofagus (Nothofagaceae)) from South America is revised. The genus Paraulax and its type species, P. perplexa, are redescribed and ...
Heterogeneous genetic structure in a natural population of Raulí (Nothofagus nervosa)
(Pontificia Universidad Catolica de Chile, Facultad de Agronomia e Ingenieria Forestal, 2011)
Heterozygote deficiencies in natural populations of outbreeding tree species are common and thought to be due mainly to biparental inbreeding. Inbreeding is believed to be caused by family structure within populations, a ...
First description of the breeding nest of Irenomys tarsalis, a sigmodontine rodent endemic to southern Andean forestsPrimera descripción del nido de Irenomys tarsalis, un roedor sigmodontino endémico de los bosques subandinos
The Chilean tree rat, Irenomys tarsalis is a rare sigmodontine endemic to the Southern Andean forests and very little is known about its habits. The aim of this work was to describe its breeding nest. The nest was located ...
Pollen morphology of Nothofagus (Nothofagaceae, Fagales) and its phylogenetic significance
(De Gruyter, 2016-12)
Nothofagaceae (southern beeches) are a relatively small flowering plant family of trees confined to the Southern Hemisphere. The fossil record of the family is abundant and it has been widely used as a test case for the ...
Karyotype variation in the South American aphid genus Neuquenaphis (Hemiptera, Aphididae, Neuquenaphidinae)
(Blackwell Publishing, Inc., 2008)
Global distribution, diversity hotspots and niche transitions of an astaxanthin-producing eukaryotic microbe
Microbes establish very diverse but still poorly understood associations with other microscopic or macroscopic organisms that do not follow the more conventional modes of competition or mutualism. Phaffia rhodozyma, an ...
Pinus ponderosa alters nitrogen dynamics and diminishes the climate footprint in natural ecosystems of Patagonia
1. Understanding climate effects on plant?soil interactions in terrestrial ecosystems remains challenging due to the fact that floristic composition covaries with climate, particularly along rainfall gradients. It is ...
Integrating genetics and suitability modelling to bolster climate change adaptation planning in Patagonian Nothofagus forests
(Springer Heidelberg, 2017-10)
We investigated the impact of past changes in habitat suitability on the current patterns of genetic diversity of two southern beeches (Nothofagus nervosa and Nothofagus obliqua) in their eastern fragmented range in ...
