Alessandro Minelli Taxonomy Faces Speciation: the Origin of Species Or Biodiversity Journal , 2015, 6 (1): 123–138 MONOGRAPH Taxonomy faces speciation: the origin of species or the fading out of the species? Alessandro Minelli Department of Biology, University of Padova, Via Ugo Bassi 58 B, I 35131 Padova, Italy; email: [email protected] ABSTRACT Efficient field sampling and new investigation tools, including barcoding and other molecular techniques, are bringing to light an unexpected wealth of new species, including sets of morphologically quite uniform, but genetically distinct cryptic species. On the other hand, increasing appreciation of the dynamic nature of the species and a better knowledge of speciation processes and introgression phenomena challenges the taxonomists’ efforts to shoehorn all diversity of life into a formal classification of which the species would be the basic unit. Unfortunately, there is probably not a single best notion of species, either in theory or in practice. KEY WORDS barcoding; cryptic species; hybridization; speciation; species concepts.

Beatty3, Renato Nunes2,4, Camilo Salazar1 and Jessica L. Ware2,5 Abstract Background: The New World Tropics has experienced a dynamic landscape across evolutionary history and harbors a high diversity of flora and fauna. While there are some studies addressing diversification in Neotropical vertebrates and plants, there is still a lack of knowledge in arthropods. Here we examine temporal and spatial diversification patterns in the damselfly family Polythoridae, which comprises seven genera with a total of 58 species distributed across much of Central and South America. Results: Our time-calibrated phylogeny for 48 species suggests that this family radiated during the late Eocene (~ 33 Ma), diversifying during the Miocene. As with other neotropical groups, the Most Recent Common Ancestor (MRCA) of most of the Polythoridae genera has a primary origin in the Northern Andes though the MRCA of at least one genus may have appeared in the Amazon Basin. Our molecular clock suggests correlations with some major geographical events, and our biogeographical modeling (with BioGeoBEARS and RASP) found a significant influence of the formation of the Pebas and Acre systems on the early diversification of these damselflies, though evidence for the influence of the rise of the different Andean ranges was mixed. Diversification rates have been uniform in all genera except one—Polythore—where a significant increase in the late Pliocene (~ 3 mya) may have been influenced by recent Andean uplift.

We suggest that misconceptions about natural selection arise from mistaken categorization. Our thesis for explaining students’ failure to understand this concept, or evolution in general, is not that they necessarily fail to understand individual Darwinian principles; rather, they often fail to understand the ontological features of equilibration processes, of which evolution is one instance. They thus attribute the evolutionary process in general, and natural selection in particular, with event-like properties. For example, naive students appear to focus on the idea of survival of the fittest, but embed this idea within an event ontology that involves actors struggling to overcome obstacles and achieve goals. Results showed that most naive subjects’ evolutionary explanations reflected an event ontology. Furthermore, event ontology attributes were positively correlated with Non-darwinian explanations; by contrast, equilibration attributes, when present, were positively correlated with key Darwinian principles.

Here, we present a molecular phylogenetic analysis of Anartia species relationships, using both mitochondrial and nuclear genes. Analyses of both data sets confirm earlier predictions of sister species pairings based primarily on genital morphology. Yet both the mitochondrial and nuclear gene phylogenies demonstrate that Anartia jatrophae is not sister to all other Anartia species, but rather that it is sister to the Anartia fatima–Anartia amathea lineage. Traditional bi- ogeographic explanations for speciation across the genus relied on A. jatrophae being sister to its congeners. These explanations invoked allopatric divergence of sister species pairs and multiple sympatric speciation events to explain why A. jatrophae flies alongside all its congeners. The molecular phylogenies are more consistent with lineage divergence due to vicariance, and range expansion of A. jatrophae to explain its sympatry with congeners. Further interpretations of the tree topologies also suggest how morphological evolution and eco-geographic adaptation may have set species range boundaries.

  • Diverse Reproductive Barriers in Hybridising Crickets Suggests Extensive Variation in the Evolution and Maintenance of Isolation
    Evol Ecol (2013) 27:993–1015 DOI 10.1007/s10682-012-9610-2 ORIGINAL PAPER Diverse reproductive barriers in hybridising crickets suggests extensive variation in the evolution and maintenance of isolation Thor Veen • Joseph Faulks • Frances Tyler • Jodie Lloyd • Tom Tregenza Received: 5 July 2012 / Accepted: 21 September 2012 / Published online: 10 November 2012 Ó Springer Science+Business Media Dordrecht 2012 Abstract Reproductive barriers reduce gene flow between populations and maintain species identities. A diversity of barriers exist, acting before, during and after mating. To understand speciation and coexistence, these barriers need to be quantified and their potential interactions revealed. We use the hybridising field crickets Gryllus bimaculatus and G. campestris as a model to understand the full compliment and relative strength of reproductive barriers. We find that males of both species prefer conspecific females, but the effect is probably too weak to represent a barrier. In contrast, prezygotic barriers caused by females being more attracted to conspecific male song and preferentially mounting and mating with conspecifics are strong and asymmetric. Postzygotic barriers vary in direction; reductions in fecundity and egg viability create selection against hybridisation, but hybrids live longer than pure-bred individuals. Hybrid females show a strong preference for G. bimaculatus songs, which together with a complete lack of hybridisation by G. campestris females, suggests that asymmetric gene flow is likely. For comparison, we review repro- ductive barriers that have been identified between other Gryllids and conclude that multiple barriers are common.

This trap collected arthropods for twenty weeks from April 29 – September 19, 2014. All 10 Malaise trap samples were processed; every other sample was analyzed using the individual specimen protocol while the second half was analyzed via bulk analysis. A total of 3029 BINs were obtained. Over half the BINs captured were flies (Diptera), followed by bees, ants and wasps (Hymenoptera), moths and butterflies (Lepidoptera), and true bugs (Hemiptera; Figure 2). In total, 595 arthropod species were named, representing 21.3% of the BINs from the Figure 1. Malaise trap deployed at Awenda Provincial site (Appendix 1).

  • Genome Analysis of Ranavirus Frog Virus 3Isolated from American Bullfrog
    www.nature.com/scientificreports OPEN Genome analysis of Ranavirus frog virus 3 isolated from American Bullfrog (Lithobates catesbeianus) in South America Marcelo Candido 1*, Loiane Sampaio Tavares1, Anna Luiza Farias Alencar2, Cláudia Maris Ferreira3, Sabrina Ribeiro de Almeida Queiroz1, Andrezza Maria Fernandes1 & Ricardo Luiz Moro de Sousa1 Ranaviruses (family Iridoviridae) cause important diseases in cold-blooded vertebrates. In addition, some occurrences indicate that, in this genus, the same virus can infect animals from diferent taxonomic groups. A strain isolated from a Ranavirus outbreak (2012) in the state of Sao Paulo, Brazil, had its genome sequenced and presented 99.26% and 36.85% identity with samples of Frog virus 3 (FV3) and Singapore grouper iridovirus (SGIV) ranaviruses, respectively. Eight potential recombination events among the analyzed sample and reference FV3 samples were identifed, including a recombination with Bohle iridovirus (BIV) sample from Oceania. The analyzed sample presented several rearrangements compared to FV3 reference samples from North America and European continent. We report for the frst time the complete genome of Ranavirus FV3 isolated from South America, these results contribute to a greater knowledge related to evolutionary events of potentially lethal infectious agent for cold-blooded animals. Among the major viral pathogens, worldwide distributed and recent history, Ranavirus (Rv) is highlighted, on which, studies in South America remain limited. Rv are part of the family Iridoviridae that is divided into fve genera, of which three are considered more relevant by infectious severity in aquatic and semi-aquatic animals: Lymphocystivirus, Megalocytivirus and Rv. Tey are enveloped and unenveloped viruses, showing double-stranded DNA whose genome ranges from 103 to 220 kbp.
