Ciliate Environmental Diversity Can Be Underestimated by the V4 Region of SSU rDNA: Insights from Species Delimitation and Multilocus Phylogeny of Pseudokeronopsis (Protist, Ciliophora)

open access: yesMicroorganisms, 2019
Metabarcoding and high-throughput sequencing methods have greatly improved our understanding of protist diversity. Although the V4 region of small subunit ribosomal DNA (SSU-V4 rDNA) is the most widely used marker in DNA metabarcoding of eukaryotic ...

Phylogeny of Twenty-One Mammals [PDF]

open access: yesarXiv, 2023
Phylogeny can be inferred using two sources of data from an organism: morphological data and molecular data. Historically, phylogenies were usually inferred using morphological characters, but some morphological features may not necessarily indicate shared heritage.

Phylogeny as population history [PDF]

open access: yes, 2013
The construction and use of phylogenetic trees is central to modern systematics. But it is unclear exactly what phylogenies and phylogenetic trees represent.

The mitochondrial genome of Lamellomphalus manusensis Zhang & Zhang, 2017 (Gastropoda: Neomphalida) from deep-sea hydrothermal vent

open access: yesMitochondrial DNA. Part B. Resources, 2022
We report the nearly complete mitochondrial genome sequence of Lamellomphalus manusensis Zhang and Zhang , a deep-sea snail inhabiting hydrothermal vent. The mitogenome is 15,990 bp in length, has a base composition of A (35.7%), T (33.5%), C (15.4%) and

Extensions of results on phylogeny graphs of degree bounded digraphs [PDF]

open access: yesarXiv, 2022
An acyclic digraph in which every vertex has indegree at most $i$ and outdegree at most $j$ is called an $(i,j)$ digraph for some positive integers $i$ and $j$. The phylogeny graph of a digraph $D$ has $V(D)$ as the vertex set and an edge $uv$ if and only if one of the following is true: $(u,v) \in A(D)$; $(v,u) \in A(D)$; $(u,w) \in A(D)$ and $(v,w ...

Circumscription and phylogeny of the Laurales [PDF]

open access: yes, 1999
The order Laurales comprises a few indisputed core constituents, namely Gomortegaceae, Hernandiaceae, Lauraceae, and Monimiaceae sensu lato, and an equal number of families that have recently been included in, or excluded from, the order, namely ...
