A global phylogeny of leafmining Ectoedemia moths (Lepidoptera: Nepticulidae): exploring host plant family shifts and allopatry as drivers of speciation
Provedor de dados: Naturalis Digital Academic Repository
Autores: Doorenweerd, C.; Nieukerken, E.J. van; Menken, S.B.J.
Background: Host association patterns in Ectoedemia (Lepidoptera: Nepticulidae) are also encountered in other insect groups with intimate plant relationships, including a high degree of monophagy, a preference for ecologically dominant plant families (e.g. Fagaceae, Rosaceae, Salicaceae, and Betulaceae) and a tendency for related insect species to feed on related host plant species. The evolutionary processes underlying these patterns are only partly understood, we therefore assessed the role of allopatry and host plant family shifts in speciation within Ectoedemia. Methodology: Six nuclear and mitochondrial DNA markers with a total aligned length of 3692 base pairs were used to infer phylogenetic relationships among 92 species belonging to the subgenus...

Large-scale evolutionary patterns of host plant associations in the Lepidoptera
Provedor de dados: Naturalis Digital Academic Repository
Autores: Menken, S.B.J.; Boomsma, J.J.; Nieukerken, E.J. van.
We characterized evolutionary patterns of host plant use across about 2500 species of British Lepidoptera, using character optimization and independent phylogenetic contrasts among 95 operational taxa, and evaluated the extent to which caterpillars are monophagous, use woody host plants, and feed concealed. We also analyzed the use of different Angiosperm superorders and related these associations to other key variables. The Nepticulidae, Pterophoridae, and Gracillariidae allowed explicit comparisons between the British fauna and the Lepidoptera worldwide, which indicated that our broad categorizations for Britain are accurate predictors for the global fauna. The first (lower glossatan) radiation of the Lepidoptera started with monophagous, internal...

Revision of agents of black-grain eumycetoma in the order Pleosporales
Provedor de dados: Naturalis Digital Academic Repository
Autores: Ahmed, S.A.; Sande, W.W.J. van de; Stevens, D.A.; Fahal, A.; Diepeningen, A.D. van; Menken, S.B.J.; Hoog, G.S. de.
Eumycetoma is a chronic fungal infection characterised by large subcutaneous masses and the presence of sinuses discharging coloured grains. The causative agents of black-grain eumycetoma mostly belong to the orders Sordariales and Pleosporales. The aim of the present study was to clarify the phylogeny and taxonomy of pleosporalean agents, viz. Madurella grisea, Medicopsis romeroi (syn.: Pyrenochaeta romeroi), Nigrograna mackinnonii (syn. Pyrenochaeta mackinnonii), Leptosphaeria senegalensis, L. tompkinsii, and Pseudochaetosphaeronema larense. A phylogenetic analysis based on ﬁve loci was performed: the Internal Transcribed Spacer (ITS), large (LSU) and small (SSU) subunit ribosomal RNA, the second largest RNA polymerase subunit (RPB2), and translation...

A Clarification of the Status of Four Taxa in the Ectoedemia Angulifasciella Group (Nepticulidae: Lepidoptera)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Wilkinson, C.; Bryan, G.; Menken, S.B.J.; Nieukerken, E.J. van.
The status of the four taxa Ectoedemia angulifasciella, E. atricollis, E. rubivora and E. arcuatella, has always been in debate. They have now been studied using several different systematic methods, relating to morphology, gel electrophoresis, host plant differentiation, life histories and distribution. Evidence is given here which demonstrates that they should be regarded as two pairs of sibling species.

Phylogeography, genetic diversity and structure of the poecilosclerid sponge Phorbas fictitius at oceanic islands
Provedor de dados: Naturalis Digital Academic Repository
Autores: Xavier, J.R.; Soest, R.W.M. van; Breeuwer, J.A.J.; Martins, A.M.F.; Menken, S.B.J.
In this study we assessed the sequence variation in the I3-M11 partition of the mtDNA cytochrome c oxidase subunit I gene (COI) in ten populations of the Atlanto-Mediterranean demosponge Phorbas fictitius (Porifera: Poecilosclerida) at two spatial scales: a regional scale comparing mainland (Iberian) and insular (Macaronesian) populations, and a local (Archipelagic) scale focusing on different island populations of the Azores archipelago. A multiple approach combining diversity measures, FST estimates, phylogenetic inference and nested clade phylogeographic analysis was used to assess the genetic structure and elucidate the evolutionary history of this species. Genetic differentiation, based of FST estimates, was found among most populations at both scales...

Low genetic variability in the endangered Colombian endemic freshwater turtle Podocnemis lewyana (Testudines, Podocnemididae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Vargas-Ramírez, M.; Chiari, Y.; Castaño-Mora, O.V.; Menken, S.B.J.
The Magdalena River Turtle (Podocnemis lewyana) is a Colombian endemic species, endangered due to human exploitation and habitat destruction. To date, this species is poorly known ecologically and data on its genetic diversity are lacking. Here we report on the first genetic survey of the species across its distribution range. We obtained mitochondrial DNA sequences (488 bp) of the cytochrome b gene from 109 individuals. Samples belong to populations located at several different localities, grouped in five regions, along the four main river basins: Magdalena, Cauca, San Jorge, and Sinú drainages. We found two haplotypes, which differ in only one nucleotide substitution and which are represented with different frequencies in the five geographic regions....
