Alfred Russel Wallace and the Darwinian Species Concept: His Paper on the Swallowtail Butterflies (Papilionidae) of 1865
Provedor de dados: 72
Autores: Mallet,James.
Soon after his return from the Malay Archipelago, Alfred Russel Wallace published one of his most signifcant papers. The paper used butterfies of the family Papilionidae as a model system for testing evolutionary hypotheses, and included a revision of the Papilionidae of the region, as well as the description of some 20 new species. Wallace argued that the Papilionidae were the most advanced butterfies, against some of his colleagues such as Bates and Trimen who had claimed that the Nymphalidae were more advanced because of their possession of vestigial forelegs. In a very important section, Wallace laid out what is perhaps the clearest Darwinist defnition of the differences between species, geographic subspecies, and local ‘varieties.’ He also discussed...

Introducing the Consolidated Species Concept to resolve species in the Teratosphaeriaceae
Provedor de dados: 16
Autores: Quaedvlieg, W.; Binder, M.; Groenewald, J.Z.; Summerell, B.A.; Carnegie, A.J.; Burgess, T.I.; Crous, P.W.
The Teratosphaeriaceae represents a recently established family that includes numerous saprobic, extremophilic, human opportunistic, and plant pathogenic fungi. Partial DNA sequence data of the 28S rRNA and RPB2 genes strongly support a separation of the Mycosphaerellaceae from the Teratosphaeriaceae, and also provide support for the Extremaceae and Neodevriesiaceae, two novel families including many extremophilic fungi that occur on a diversity of substrates. In addition, a multi-locus DNA sequence dataset was generated (ITS, LSU, Btub, Act, RPB2, EF-1α and Cal) to distinguish taxa in Mycosphaerella and Teratosphaeria associated with leaf disease of Eucalyptus, leading to the introduction of 23 novel genera, ﬁve species and 48 new combinations. Species...

Zoogeography of primates in insular Southeast Asia: species-area relationships and the effects of taxonomy
Provedor de dados: 16
Autores: Nijman, V.; Meijaard, E.
Given its complex zoogeography and large number of islands insular Southeast Asia makes an excellent subject for studying the interrelationships of species richness, island area and isolation. The islands are merely highpoints of an immense shallow continental shelf which during Pleistocene glacial periods was exposed periodically as dry land connecting the now isolated islands with one another. The area is home to a large number of primate taxa, including many endemic to the region (Nasalis, Presbytis, Pongo, Symphalangus, Simias, Tarsius). Worldwide, the number of described (extant) species of primates has doubled in the last two decades partially as a result of applying a different species concept (viz. Phylogenetic Species Concept PSC as opposed to the...

Evaluating methodologies for species delimitation: the mismatch between phenotypes and genotypes in lichenized fungi (Bryoria sect. Implexae, Parmeliaceae)
Provedor de dados: 16
Autores: Boluda, C.G.; Rico, V.J.; Divakar, P.K.; Nadyeina, O.; Myllys, L.; McMullin, R.T.; Zamora, J.C.; Scheidegger, C.; Hawksworth, D.L.
In many lichen-forming fungi, molecular phylogenetic analyses lead to the discovery of cryptic species within traditional morphospecies. However, in some cases, molecular sequence data also questions the separation of phenotypically characterised species. Here we apply an integrative taxonomy approach ‒ including morphological, chemical, molecular, and distributional characters ‒ to re-assess species boundaries in a traditionally speciose group of hair lichens, Bryoria sect. Implexae. We sampled multilocus sequence and microsatellite data from 142 specimens from a broad intercontinental distribution. Molecular data included DNA sequences of the standard fungal markers ITS, IGS, GAPDH, two newly tested loci (FRBi15 and FRBi16), and SSR frequencies from 18...

Response paper: Morphometric article by Mejía et al. 2015 alluding genera Herichthys and Nosferatu displays serious inconsistencies
Provedor de dados: 83
Autores: Maza-Benignos,Mauricio de la; Lozano-Vilano,Ma. de Lourdes; García-Ramírez,María Elena.
ABSTRACT In the present response paper, the article entitled "Morphometric variation of the Herichthys bartoni (Bean, 1892) species group (Teleostei: Cichlidae): How many species comprise H. labridens (Pellegrin, 1903)?" by Mejía et al . 2015 is critically reviewed. The current review pinpoints some of the more conspicuous conceptual inconsistencies and fundamental errors found in the study by Mejía et al . (2015), It is contended that the authors fail to provide any new insights into the complex biogeography and evolutionary history of the Nosferatu and Herichthys genus groups, and that while results of their Cox1 molecular analysis are comparable to those by De la Maza-Benignos et al . (2015), the conclusions of the two studies are not comparable. In...

An alternative species taxonomy of the birds of Mexico
Provedor de dados: 49
Autores: Navarro-Sigüenza,Adolfo G.; Peterson,A. Townsend.
Extensive debate has surrounded the application of alternative species concepts in Ornithology. The biological species concept (BSC) and phylogenetic species concept (PSC) have typically been set in opposition, with extensive debate on the relative merits of each. An alternative is the evolutionary species concept (ESC), which offers a perspective similar to that of the PSC, yet with several significant differences. To date, no major avifauna has been examined and compared among taxonomic viewpoints. Herein, we develop an alternative phylogenetic/evolutionary species taxonomy to the current BSC treatment for the more than 1000 bird species of Mexico. A total of 135 biological species was divided to produce a total of 323 phylogenetic/evolutionary species,...
