The Phylogenetic Relationships of the Family Sciaenidae Based on Genome-Wide Data Analysis

open access: yesAnimals, 2022
Uncertainty and controversy exist in the phylogenetic status of the Sciaenidae family because of the limited genetic data availability. In this study, a data set of 69,098 bp, covering 309 shared orthologous genes, was extracted from 18 genomes and 5 ...

Genetic affinities within a large global collection of pathogenic Leptospira: implications for strain identification and molecular epidemiology [PDF]

open access: yes, 2010
Leptospirosis is an important zoonosis with widespread human health implications. The non-availability of accurate identification methods for the individualization of different Leptospira for outbreak investigations poses bountiful problems in the ...

PHYLOGENETIC RELATIONSHIPS AMONG WEST INDIAN XENODONTINE SNAKES (SERPENTES; COLUBRIDAE) WITH COMMENTS ON THE PHYLOGENY OF SOME MAINLAND XENODONTINES [PDF]

open access: yes, 1999
The evolutionary relationships of the West Indian (W. I.) xenodontine snake assemblage has been considered as either monophyletic or paraphyletic. Allozyme data from protein electrophoresis were used to estimate the phylogeny of the W. I.

A molecular phylogenetic analysis of the Oedipodinae and their intercontinental relationships

open access: yesJournal of Orthoptera Research, 2007
Abstract Oedipodine grasshoppers occur throughout the major continents, making them the most widely distributed of the 30 subfamilies that comprise the Acrididae. Most species have been allocated to one of 15 tribes; some remain unassigned. The subfamily, according to Vickery, had an ancient origin, just after the breakup of Pangaea but before the ...

Aging Is a Key Driver for Adult Acute Myeloid Leukemia

open access: yesAging and Cancer, EarlyView.
Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

The gyrB gene is a useful phylogenetic marker for exploring the diversity of flavobacterium strains isolated from terrestrial and aquatic habitats in Antarctica [PDF]

open access: yes, 2011
Within the phylum Bacteroidetes, the gyrB gene, encoding for the B subunit of the DNA gyrase, has been used as phylogenetic marker for several genera closely related to Flavobacterium.

Phylogenetic relationships in A-genome species of rice as revealed by RAPD analysis

open access: yesGenes & Genetic Systems, 1996
In order to clarify the phylogenetic relationships in A-genome species of rice, RAPD analysis was carried out using 29 accessions (8 Oryza sativa, 6 O. glaberrima, 13 O. perennis, and 2 O. breviligulata). Their total DNA was used as template for PCR with 14 decamer primers.

UTact: Underwater Vision‐Based Tactile Sensor with Geometry Reconstruction and Contact Force Estimation

open access: yesAdvanced Robotics Research, EarlyView.
Embedded flexible sensing technologies advance underwater soft robotics, yet most systems still suffer from hysteresis and limited perceptiveness. Instead, vision‐based tactile sensors provide reliable and rapid feedback essential for complex underwater tasks.

Understanding drivers of species distribution change: a trait-based approach [PDF]

open access: yes, 2013
The impacts of anthropogenic environmental change on biodiversity are well documented, with threats such as habitat loss and climate change identified as causes of change in species distributions.
