The composition of arbuscular mycorrhizal fungal communities in the roots of a ruderal forb is not related to the forest fragmentation process
(Wiley Blackwell Publishing, Inc, 2015-01)
Land-use changes and forest fragmentation have strong impact on biodiversity. However, little is known about the influence of new landscape configurations on arbuscular mycorrhizal fungal (AMF) community composition. We ...
Phylogenentic and enzymatic characterization of psychrophilic and psychrotolerant marine bacteria belong to γ-Proteobacteria group isolated from the sub-Antarctic Beagle Channel, Argentina
(Springer, 2014-09)
The phylogenetic and physiological characteristics of cultivable-dependent approaches were determined to establish the diversity of marine bacteria associated with the intestines of benthonic organisms and seawater samples ...
DNA barcoding of Phymaturus lizards reveals conflicts in species delimitation within the patagonicus clade
(Society for the Study of Amphibians and Reptiles, 2016-12)
Under the DNA Barcode initiative, we used the mitochondrial locus cytochrome c oxidase I (COI) to test if this molecular marker would reliably distinguish among lizard species of the patagonicus clade of Phymaturus. Using ...
Evolution of complex symbiotic relationships in a morphologically derived family of lichen-forming fungi
(Wiley Blackwell Publishing, Inc, 2015-12)
- We studied the evolutionary history of the Parmeliaceae (Lecanoromycetes, Ascomycota), one of the largest families of lichen-forming fungi with complex and variable morphologies, also including several lichenicolous ...
Nitrospina-like bacteria are the main drivers of nitrite oxidation in the seasonal upwelling area of the Eastern South Pacific (central Chile ~36° S).
(2014)
plays a key role in the nitrification process. Marine bacteria involved in this nitrate-producing process have however been seldom studied compared with the ammonia-oxidizing community. Here, we report for the first time ...
Caracterização molecular de arqueias em rejeitos siderúrgicos
(Universidade Federal de Minas GeraisUFMG, 2013-02-28)
Mining and activities arising from it, such as steel, are considered crucial to economic development, but is responsible for many environmental damage. The steelmaking process generates 700 kg of wastes per ton of steel ...
Caracterización de la comunidad de hongos endófitos asociados a la raíz de Pleurothallis coriacardia y evaluación de su efecto en el desarrollo de sus semillas
(2017-07-12)
The family Orchidaceae is recognized as an important plant-group due to their mutualistic interactions with fungi assembling mycorrhiza interactions. Despite the abundant information about mycorrhizal relationships, the ...
Genetic and Chromosomal Differentiation of Rhamdia quelen (Siluriformes, Heptapteridae) Revealed by Repetitive Molecular Markers and DNA Barcoding
(Mary Ann Liebert, Inc, 2018-09-18)
Rhamdia quelen, a species of Heptapteridae, is considered to be a complex because of taxonomic and phylogenetic inconsistencies. Determining the physical location of repetitive DNA sequences on the chromosomes and the DNA ...
