A macrogenomic investigation of a Holarctic clade of black flies—the Simulium cholodkovskii lineage—provided a platform to explore the implications of a unique, synapomorphic whole-arm interchange in the evolution of black flies. Nearly 60 structural rearrangements were discovered in the polytene complement of the lineage, including 15 common to all 138 analyzed individuals, relative to the central sequence for the entire subgenus Simulium. Three species were represented, of which two… Expand
Genetic variation in a colonization specialist, Simulium ruficorne (Diptera: Simuliidae), the world’s most widely distributed black fly
TLDR
It is suggested that dispersal and colonization specialists, such as S. ruficorne, are multivoltine inhabitants of temporary streams, and must relocate as their habitats deteriorate, perhaps largely physiological in nature,such as tolerance of high temperatures and droughts. Expand
Karyotypic Characteristics of the Ornithophilic Simulium aureum Species Group (Diptera: Simuliidae) Along the Northern Black Sea Coast and the Origin of Chromosomal Reduction
TLDR
It is shown that S. krymense has a banding sequence most similar to the hypothesized ancestral form of the S. aureum group, and that the entire group is derived from within the Simulium vernum Group, rendering the latter group and its encompassing subgenus, Nevermannia Enderlein, paraphyletic.

Vietnam, a Hotspot for Chromosomal Diversity and Cryptic Species in Black Flies (Diptera: Simuliidae)
TLDR
Phylogenetic inference based on uniquely shared, derived chromosomal rearrangements supports the clustering of cytoforms into two primary lineages, theSimulium tani complex and the Southeast Asian Simulium tuberosum subgroup. Expand
River-specific macrogenomic diversity in Simulium guianense s. l. (Diptera: Simuliidae), a complex of tropical American vectors associated with human onchocerciasis
TLDR
A high level of variation involving 83 macrogenomic rearrangements across 25 populations in Brazil, French Guiana, and Venezuela is revealed, suggesting a high degree of fidelity to the specialized breeding habitats—rocky shoals—of the natal rivers of S. guianense s. Expand
Biodiversity of Simulium metallicum sensu lato (Diptera: Simuliidae), a complex of Neotropical vectors associated with human onchocerciasis.
TLDR
The polytene chromosomes of 130 larvae of the Neotropical Simulium metallicum complex from Brazil, Costa Rica, and Ecuador revealed five cytoforms, including three that are new and two that represent range extensions of up to 850km, bringing the total number in the complex to 17. Expand
The State of Phylogenetic Analysis: Narrow Visions and Simple Answers-Examples from the Diptera (flies).
TLDR
Current phylogenetic analyses have come to increasingly depend on DNA sequence-based characters, in spite of their tumultuous history of inconsistent results, so they should be viewed with caution and certainly not as a panacea as they are commonly portrayed. Expand
A near-chromosome level genome assembly of Anopheles stephensi
TLDR
Olfactory receptors with the potential for host recognition in the genus Anopheles are identified and a comparative analysis of the genomes suggests limited inter-chromosomal gene flow and chromosomal arm switching with a potential role in adaptive radiation within the genusAnopheles. Expand
Patterns, Mechanisms and Genetics of Speciation in Reptiles and Amphibians
TLDR
The research on different aspects of speciation in reptiles and amphibians, including biogeography and climatic niches, ecological speciation, the relationship between speciation rates and phenotypic traits, and genetics and genomics is reviewed. Expand
The evolution of insect metallothioneins
TLDR
The evolutionary history of MTs in insects is reconstructed by combining phylogenetics and synteny analysis and it is shown that the MT content in insects has been shaped by lineage-specific tandem duplications from a single ancestral MT. Expand
The Evolution of Insect Metallothioneins
TLDR
The evolutionary history of MTs in insects is reconstructed by combining phylogenetics and synteny analysis and it is shown that the MT content in insects has been shaped by lineage-specific tandem duplications from a single ancestral MT. Expand

Cytosystematics of the Simulium tuberosum group (Diptera: Simuliidae) in Thailand.
TLDR
The polytene chromosomes of 3347 larvae of the Simulium tuberosum group in Asia were analysed, representing the largest ever cytogenetic study of black flies in the Oriental Region and revealed 17 cytogenetically distinct taxa in Thailand, plus an 18th in China. Expand
Integrated Systematics of the Simuliidae (Diptera): Evolutionary Relationships of the Little-Known Palearctic Black Fly Simulium acrotrichum
TLDR
Structural and chromosomal features indicate that S. acrotrichum is the sister species of S. flavidum Rubtsov, a black fly from Central Asia, and argue for an integrated approach to simuliid systematics, drawing from the character stores of morphology, cytology, and molecular biology. Expand
Cytogenetics and evolution of Simulium ornatipes skuse (Diptera:Simuliidae) I. Sibling speciation
TLDR
It is concluded that the shared polymorphisms in fact originate from a common ancestor and an unprecedented level of shared inversion polymorphism is shown by S. ornatipes A and B indicating a very close relationship between them. Expand

Cryptic biodiversity in the cytogenome of bird‐biting blackflies in North Africa
TLDR
Bird‐biting blackflies in the Simulium (Eusimulium) aureum group (Diptera: Simuliidae) are widespread vectors of Leucocytozoon and Trypanosoma parasites, and seven chromosomal segregates were discovered among 29 populations in Algeria and Morocco. Expand

TLDR
The chromosomally mapped European black fly Simulium colombaschense (Scopoli) reveals that the name associated with history’s worst simuliid pest represents a complex of species, two or more of which are nonpests potentially vulnerable to loss of their limited habitat. Expand

Does river corridor affect chromosome forms within the black fly Simulium arcticum complex (Diptera:Simuliidae)?
TLDR
Flies within the same river corridor were chromosomally more similar than were flies between different corridors, and comparisons between sites suggest that river distance and Euclidian distance are associated negatively with chromosomal type similarity, but river distance showed the highest similarity comparisons for any given distance.
