The genus Nipponaetes (Hymenoptera: Ichneumonidae: Cryptinae) in Costa Rica, with a reassessment of the generic limits

open access: yesEuropean Journal of Entomology, 2004
The endemic Costa Rican genus Zurquilla Gauld, 1997, is transferred from the ichneumonid subfamily Tryphoninae (tribe Oedemopsini) to the Cryptinae (tribe Phygadeuontini) and synonymised with Nipponaetes Uchida, 1933.

Identificación molecular mediante código de barras de DNA de moscas Lucilia (Diptera: Calliphoridae) recolectadas en Costa Rica

open access: yesTecnología en Marcha, 2020
La identificación del género Lucilia es importante cuando se recolectan adultos o larvas en casos forenses porque el intervalo post-mortem puede ser estimado. En este trabajo se analizó morfológica y molecularmente un panel de especímenes de Lucilia (n =

Computational discovery of hidden breaks in 28S ribosomal RNAs across eukaryotes and consequences for RNA Integrity Numbers

open access: yesScientific Reports, 2019
In some eukaryotes, a ‘hidden break’ has been described in which the 28S ribosomal RNA molecule is cleaved into two subparts. The break is common in protostome animals (arthropods, molluscs, annelids etc.), but a break has also been reported in some ...

Genetic divergence of tanaidaceans (Crustacea: Peracarida) with low dispersal ability

open access: yesScientia Marina, 2014
In this study, the phylogeographic patterns of nuclear, ribosomal and mtDNA gene fragments of five tanaidacean species (Zeuxo, Tanaidae) from the Atlantic, Pacific and Mediterranean Sea were investigated. We aimed to interpret results in the framework of

Molecular and morphological characterization of Tylenchus zeae n. sp. (Nematoda: Tylenchida) from Corn (Zea mays) in South Carolina

open access: yesJournal of Nematology, 2023
Specimens of a tylenchid nematode were recovered in 2019 from soil samples collected from a corn field, located in Pickens County, South Carolina, USA. A moderate number of Tylenchus sp. adults (females and males) were recovered. Extracted nematodes were

Expression of distinct maternal and somatic 5.8S, 18S, and 28S rRNA types during zebrafish development

open access: yesRNA: A publication of the RNA Society, 2017
There is mounting evidence that the ribosome is not a static translation machinery, but a cell-specific, adaptive system. Ribosomal variations have mostly been studied at the protein level, even though the essential transcriptional functions are ...

Annotated 18S and 28S rDNA reference sequences of taxa in the planktonic diatom family Chaetocerotaceae

open access: yesPLoS ONE, 2018
The species-rich diatom family Chaetocerotaceae is common in the coastal marine phytoplankton worldwide where it is responsible for a substantial part of the primary production.

Analysis of small and large subunit rDNA introns from several ectomycorrhizal fungi species.

open access: yesPLoS ONE, 2021
The small (18S) and large (28S) nuclear ribosomal DNA (rDNA) introns have been researched and sequenced in a variety of ectomycorrhizal fungal taxa in this study, it is found that both 18S and 28S rDNA would contain introns and display some degree ...

Polycladida phylogeny and evolution: integrating evidence from 28S rDNA and morphology

open access: yesOrganisms Diversity & Evolution, 2017
Polyclad flatworms have a troubled classification history, with two contradicting systems in use. They both rely on a ventral adhesive structure to define the suborders Acotylea and Cotylea, but superfamilies were defined according to eyespot arrangement
