Disentangling morphologically similar species of the Andean forest: Integrating results from multivariate morphometric analyses, niche modelling and climatic space comparison in Kaunia (Eupatorieae: Asteraceae)
(Wiley Blackwell Publishing, Inc, 2018-01)
Six subtropical montane forest Kaunia spp. are remarkable for their superficial morphological similarity. We aim to explore different sources of data to clarify species delimitation in this complex of Kaunia. Morphological ...
Multivariate studies of Ipheion (Amaryllidaceae, Allioideae) and related genera
(Springer Wien, 2013)
Determination of ochratoxin A in coffee and tea samples by coupling second-order multivariate calibration and fluorescence spectroscopy
(Elsevier Science, 2020-11-01)
A new method to quantify the mycotoxin ochratoxin A (OTA) in coffee and tea samples is proposed based on second-order multivariate calibration and excitation-emission fluorescence matrix (EEFM) data. Experimental conditions ...
A Morphometric Approach in South American Stipoids with Plumose and Pappus-Like Awns
(American Society of Plant Taxonomists, 2020-05-13)
Within grasses, the tribe Stipeae is highly specialized by the presence of only one fruit per spikelet and characterized by the diversity in the ornamentation of the floret. Our aim was to analyze similarities and differences ...
Multivariate Morphometric Confirmation of Solidago chilensis (Asteraceae: Astereae) in Azores
(Guy Nesom, 2017-06-01)
An herbarium collection of Solidago from near Pico Island, Azores, Portugal, is reported here tobe Solidago chilensis Meyen. One collection (Botelho Gonçalves 1825, BM) was included in amultivariate morphometric analysis ...
A multivariate morphometric delimitation of species boundaries in the South American genus Nicoraepoa (Poaceae: Pooideae: Poeae)
(Springer Wien, 2018-05)
A multivariate morphometric study of the genus Nicoraepoa was carried out to examine patterns of morphological variation among the species and to identify additional characters to allow a clearer delimitation among species. ...
Species delimitation in the Sporobolus aeneus complex (Zoysieae, Chloridoideae, Poaceae) using the phylogenetic species concept
(Wiley, 2010-12)
The "Sporobolus aeneus complex" constitutes a morphologically well‐defined group of species with lax, exerted, pyramidal panicles with verticillate branches, and comprises 14 species and six infraspecific taxa in southern ...
Preliminary geochemical study of thermal waters at the Puracé volcano system (South Western Colombia): An approximation for geothermal exploration
(Universidad Industrial de Santander, 2018-01-01)
The Puracé Volcano is located in the Cauca department, SW of Colombia, along the Coconucos volcanic chain. This volcano is an interesting target for geothermal exploration, because it is a young caldera-type volcano, with ...
