The fundamental value of universal nomenclatural systems in biology is that they enable unambiguous scientific communication. However, the stability of these systems is threatened by recent discussions asking for a fairer nomenclature, raising the possibility of bulk revision processes for "inappropriate" names. It is evident that such proposals come from very deep feelings, but we show how they can irreparably damage the foundation of biological communication and, in turn, the sciences that depend ...

Abstract Tephrocactus comprises species mainly endemic to Argentina. Molecular phylogenetic analyses of all proposed species of the genus as well as classical (chromosome number, karyotype) and molecular cytogenetical techniques (DNA content, heterochromatin amount, rDNA genes) were conducted. Sequence data of two plastid DNA markers of Tephrocactus taxa were analyzed. Evolution of character states of cytogenetical and morphological (growth form, presence of leaves, glochids and tepal spiny mucrons, ...

A high proportion of plant species is predicted to be threatened with extinction in the near future. However, the threat status of only a small number has been evaluated compared with key animal groups, rendering the magnitude and nature of the risks plants face unclear. Here we report the results of a global species assessment for the largest plant taxon evaluated to date under the International Union for Conservation of Nature (IUCN) Red List Categories and Criteria, the iconic Cactaceae (cacti). ...

Setiechinopsis is a monotypic Argentine endemic genus (S. mirabilis) of the tribe Trichocereeae. It is one of the most difficult cacti to find and grows in lowlands and brackish soils. Our aim was to analyze for the first time its cytogenetic features in two populations. It presented 2n = 22 with small chromosomes (mean chromosome length = 2.87 μm; mean haploid genome length = 31.60 μm). The karyotype was symmetrical: 10m 1sm. The first m pair (No. 1) had nucleolar organizing regions and terminal microsatellites ...

The South American genus Gymnocalycium (Cactoideae-Trichocereae) demonstrates how the sole use of morphological data in Cactaceae results in conflicts in assessing phylogeny, constructing a taxonomic system, and analyzing trends in the evolution of the genus.Molecular phylogenetic analysis was performed using parsimony and Bayesian methods on a 6195-bp data matrix of plastid DNA sequences (atpI-atpH, petL-psbE, trnK-matK, trnT-trnL-trnF) of 78 samples, including 52 species and infraspecific taxa representing ...

We provide a short history of the development of phylogenetic concepts for the cactus family in the pre-molecular (here meaning pre-DNA) era, beginning from the creation of the first artificial classification systems, over to natural systems, and on to the progress made in the Post-Darwinian era. Although several authors have presented their ideas on the evolution of Cactaceae, it was the botanists Alwin Berger and Franz Buxbaum who made the most essential contributions towards a cactus phylogeny ...

Karyotypes of the seven Pyrrhocactus species were studied for the first time with Feulgen staining and CMA/DAPI banding. All showed 2n = 22 (x = 11). The karyotypes were symmetrical with 9m + 2sm pairs, excepting P. catamarcensis with 8m + 2sm + 1st pairs. They had a terminal microsatellite on short arms of pair #1. Pyrrhocactus bulbocalyx possessed a second satellited pair (#2) exclusively detected with Feulgen. Increasing asymmetry was associated with a decline in karyotype size. Fluorochrome banding, applied ...

This book presents the stories of three avid field biologists who over the course of 15 years frequently traveled together in search of cacti in Bolivia, Peru, and Argentina. The conversational style of this travelogue allows us to share in the authors' excitement as they encounter plants that have rarely, if ever, been written about. Nearly 195 remarkable color photographs accompany the vivid descriptions of unusual cacti growing alongside non-succulent plants, at altitudes of 8000 feet or more- ...

Based on historic reports, cytological evidence, bibliographic references, and taxonomic evidence from herbarium specimens and in the field, this paper concludes that the common prickly-pear plant, Opuntia, a horticultural plant whose domestication began 9000 years ago by the ancient Mexicans, has been divided erroneously into various species. During domestication from the wild species (2X), O. ficus-indica species acquired a higher ploidy (6X and 8X) level through natural hybridization. The present ...

Abstract The arguments towards resolving the Acacia nomenclatural controversy put forth by Thiele & al. (2011) are reviewed and rebutted. We argue that a truly pragmatic and, moreover, defensible and equitable alternative to accepting the retypification of Acacia Mill. with a conserved type would be to have the 2006 International Code of Botanical Nomenclature , excluding this retypification, serve as the basis for discussions at the Nomenclature Section of the Melbourne International Botanical Congress ...

Stem epidermis of eight Pterocactus species was examined under light microscopy (LM) and scanning electron microscopy (SEM). The stomata belong to the paracytic type, with two to five subsidiary cells. The size of stomata and papillae and the density of both were measured and counted under LM. Under SEM the micromorphology of papillae was studied. These characters were used to distinguish anatomically the species of Pterocactus.Las epidermis de los tallos de 8 especies de Pterocactus fueron examinadas ...

This paper clarifies the identity of Cereus macrogonus Salm-Dyck, the type species of the genus Trichocereus (Berger) Riccob., and specifies its synonyms and affinities. It is also intended to contribute toward stabilizing the generic nomenclature. An examination of Salm-Dyck's original description of C. macrogonus leads to an interpretation of the species, very plausibly of Peruvian origin, as a cactus which was later also named Trichocereus peruvianus Britton & Rose. A Neotype is designated that ...

We report a detailed study of the development and morphology of pollen in four species of the genus Pterocactus (Cactaceae), carried out by using LM and SEM. The anther is tetrasporangiate, its wall consists of epidermis, endothecium, one middle layer and a binucleate secretory tapetum. Microspore tetrads are tetrahedrical and pollen grains are shed at bicellular stage. Pollen grains are pantoporate, with a perforate tectum and supratectate spinules.

Brucellosis is a worldwide disease of mammals caused by Alphaproteobacteria in the genus Brucella. The genus is genetically monomorphic, requiring extensive genotyping to differentiate isolates. We utilized two different genotyping strategies to characterize isolates. First, we developed a microarray-based assay based on 1000 single nucleotide polymorphisms (SNPs) that were identified from whole genome comparisons of two B. abortus isolates , one B. melitensis, and one B. suis. We then genotyped a ...

The goal of this paper is to rehabilitate the genus Monvillea, based on Cereus cavendishii as the type species, which identity has been attributed to another genus. The name Cereus cavendishii Monville corresponds to a species of northern Argentina, Paraguay, eastern Bolivia and southern Brazil, as had been considered traditionally in the literature, and that species was typified accordingly by Heath in 1992. As a consequence, Monvillea keeps its nomenclatural validity. Additionally, an epitype ...

The first discovery of Mediocactus hahnianus was attributed to Harry Blossfeld. Based on literature analysis, it is shown that T. Rojas and A.M.

Although cultivated in Europe by Hahn, the plant is presently known only from the clone grown by J. West in the US, and obtained from Rojas in 1937. Recently, a new colony has ...
