(Tubitak Scientific & Technical Research Council Turkey, 2016-01)
Here, we studied leaflets of 18 taxa of the Dolentes-Brevipedes taxonomic complex, focusing on micromorphology, type, shape and density of trichomes. Within the non-glandular trichomes, we described three types of ...
The identity of Utricularia trinervia (Lentibulariaceae): Taxonomic re-establishment and unpublished descriptions of trap morphology
(Wiley-Blackwell, 2021-04-15)
Previous morphometric and molecular studies indicate that Utricularia amethystina is a species complex distributed in the warmer zones of the Neotropical region. It includes 31 names accepted as synonyms, mainly based on ...
Taxonomic and non-taxonomic responses of benthic macroinvertebrates to metal toxicity in tropical reservoirs: The case of cantareira complex, São Paulo, Brazil
(Academia Brasileira de Ciencias, 2020-03)
Benthic macroinvertebrates are organisms that are recognized as water quality bio-indicators. A wide variety of indices and metrics have been shown to respond to a variety of anthropogenic impacts, usually under a general ...
Endemism and taxonomic complexity of the genus Chaptalia (Asteraceae) in the Caribbean. I. Introduction and morphology
(Finnish Zoological Botanical Publishing Board, 2014-06)
The Caribbean contains a system of islands east of Central America with a high number of endemic taxa. Some of those taxa, such as the genus Chaptalia (Asteraceae) are taxonomically complex. Thirty-one species of Chaptalia ...
Harnessing the potential of integrated systematics for conservation of taxonomically complex, megadiverse plant groups
(Wiley-Blackwell, 2019-06-01)
The value of natural history collections for conservation science research is increasingly recognized, despite their well-documented limitations in terms of taxonomic, geographic, and temporal coverage. Specimen-based ...
Taxonomic Reevaluation of the Polylepis sericea Complex (Rosaceae), with the Description of a New Species
(Universidad Continental, 2019-06-30)
The taxonomically difficult genus Polylepis (Rosaceae) contains several problematic species complexes, including one around P. sericea. We here reevaluate species boundaries in this complex based on morphological characters ...
