Investigating soil mesofauna cryptic diversity: Current challenges and perspectives

Methods in Ecology and Evolution
Cryptic species lacking distinct morphological features are widespread among soil fauna, including such functionally significant groups as springtails, mites and enchytraeids.

Characterization and Phylogenetic Analysis of Chloroplast and Mitochondria Genomes from the Antarctic Polytrichaceae Species Polytrichum juniperinum and Polytrichum strictum

Diversity, 2018
In this study, the organelle genomes of Polytrichum juniperinum Hedw. and Polytrichum strictum Menzies ex Brid. (Polytrichaceae, Bryophyta) from Antarctica were sequenced and compared with the plastomes of the model moss species Physcomitrella patens ...

Detecting cryptic ghost lineage introgression in four‐taxon genomic datasets

Applications in Plant Sciences, EarlyView.
Abstract Premise Hybridization and introgression are pervasive evolutionary forces that have played fundamental roles in shaping the diversity of wild and domesticated plants. Four‐taxon tests for introgression provide a reliable framework for detecting signatures of ancient introgression from genomic data, which have played an important role in ...

HapAsmbl: A reference‐aided pipeline for assembling haplotypes in Nanopore amplicon sequence data of polymorphic populations

Applications in Plant Sciences, EarlyView.
Abstract Premise Advances in long‐read sequencing offer new possibilities to investigate haplotype diversity across multiple genes in plants and other taxa through multi‐locus, long‐read amplicon sequencing (multi‐locus LRAS). Despite this progress, there is a notable absence of dedicated bioinformatics pipelines for assembling diploid haplotypes of ...

The Phyloperiodic Approach Removes the “Cryptic Species” and Puts forward Multilevel Organismal Diversity

Diversity
The notion of the “cryptic species” has recently become an important agenda in biodiversity research. In this study, we show, by applying a periodic-like morphological and molecular framework to the nudibranch genus Cadlina from the world’s least ...

Cryptic diversity in the Japanese mantis shrimp Oratosquilla oratoria (Crustacea: Squillidae): Allopatric diversification, secondary contact and hybridization

Scientific Reports, 2017
Mounting evidence of cryptic species in the marine realm emphasizes the necessity to thoroughly revise our current perceptions of marine biodiversity and species distributions.

Comparative cytogenetics of Astyanax (Teleostei: Characidae) from the upper Paraguay basin

Neotropical Ichthyology, 2018
Astyanax is one of the most abundant and diverse taxa of fishes in the Neotropical region. In order to increase the amount of cytogenetic information for Astyanax as well as to exhibit data to subsidize future taxonomic studies, this work analyzed three ...

An osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) cranial ornamentation

The Anatomical Record, EarlyView.
Abstract Ceratopsids are among the most distinctive and well known extinct Cretaceous vertebrates, yet many details regarding the growth and composition of their cranial features are still not fully anatomically described or understood. In particular, striking cranial adornments such as the postorbital horns and parietal‐squamosal frill of Triceratops ...

Cryptic coral community composition across environmental gradients.

PLoS ONE
Cryptic genetic variation is increasingly being identified in numerous coral species, with prior research indicating that different cryptic genetic lineages can exhibit varied responses to environmental changes.

Male reproductive system in stenopodidean shrimps: Unveiling basal reproductive traits in shrimp‐like Pleocyemata (Stenopodidae and Spongicolidae)

The Anatomical Record, EarlyView.
Abstract Stenopodidea represents one of the basal lineages within Pleocyemata, yet the male reproductive system (MRS) of this group remains poorly understood, with limited information available regarding its morphology and function. This study provides the first detailed description of the MRS in four stenopodidean shrimp species from two families ...
