Mutation rates in hybrids between sibling species of Drosophila [PDF]

open access: yesHeredity, 1989
It has recently been suggested that sterility or inviability in species hybrids might result from the movement of transposable elements. Because such movement is often detectable by an increased mutation rate, I studied the effect of interspecific hybridization in the Drosophila melanogaster group on the mutation rate of X-linked visibles.

Cophenetic metrics for phylogenetic trees, after Sokal and Rohlf [PDF]

open access: yes, 2013
Phylogenetic tree comparison metrics are an important tool in the study of evolution, and hence the definition of such metrics is an interesting problem in phylogenetics.

The first record of Chironomus nuditarsis Keyl, 1961 from Sevan Lake (Armenia) confirmed by morphology, karyotype and COI gene sequence [PDF]

open access: yesComparative Cytogenetics
Chironomus nuditarsis Keyl, 1961 is recorded from Sevan Lake for the first time. This species is widespread in Europe, the Caucasus, and Siberia. For species identification, we used a comprehensive approach that included morphological, cytogenetic and ...

Reproductive isolation between two populations of Aglaoctenus lagotis , a funnel-web wolf spider [PDF]

open access: yes, 2015
Aglaoctenus lagotis (Lycosidae: Sosippinae) is a spider that, in contrast to the predominant wandering habit of the family, constructs funnel webs.

Genome architecture evolution in an invasive copepod species complex

open access: yesNature Communications
Chromosomal fusions are hypothesized to facilitate evolutionary adaptation, but empirical evidence has been scarce. Here, we analyze chromosome-level genome sequences of three sibling species within the copepod Eurytemora affinis species complex, known ...

Similar looking sisters: A new sibling species in the Pristimantis danae group from the southwestern Amazon basin (Anura, Strabomantidae) [PDF]

open access: yesZoosystematics and Evolution
We describe a new frog species that is the sibling of Pristimantis reichlei. These two sister species inhabit the Amazonian lowlands and adjacent foothills of the Andes, from central Bolivia to central Peru.

Sibling species of copepods in association with Mediterranean gorgorians

open access: yesScientia Marina, 2004
Hitherto a single species of Doridicola Leydig (Poecilostomatoida: Rhynchomolgidae) has been found reported in association with gorgonians in Europe: Doridicola botulosus (Stock and Kleeton, 1963), living on the Mediterranean gorgonian Eunicella singularis (Esper, 1791).

Graphite Co‐Intercalation Chemistry in Sodium‐Ion Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
Traditional intercalation chemistry in lithium‐ion batteries cannot allow sodium storage in graphite. The co‐intercalation chemistry changes the situation. It enables reversible and ultrafast sodium storage in graphite. Revisiting challenges and summarizing recent advances are of significant importance to exploit the full potential of graphite in ...

Recessed Microelectrodes as a Platform to Investigate the Intrinsic Redox Process of Prussian Blue Analogs for Energy Storage Application

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
A microelectrochemical analytical tool is proposed for the accelerated evaluation of the intrinsic electrochemical performance of Prussian‐blue analogues as solid active materials in Na+‐based batteries. By confining the solid active material inside a recessed microelectrode, accelerated voltammetric and galvanostatic cycling at high C‐rate become ...
