Practically delineating bacterial species with genealogical concordance [PDF]

Antonie van Leeuwenhoek, 2017
Bacterial species are commonly defined by applying a set of predetermined criteria, including DNA-DNA hybridization values, 16S rRNA gene sequence similarity, phenotypic data as well as genome-based criteria such as average nucleotide identity or digital DNA-DNA hybridization.

Individual Tree Crown Delineation Method Based on Multi-Criteria Graph Using Geometric and Spectral Information: Application to Several Temperate Forest Sites

Remote Sensing, 2022
Individual tree crown (ITC) delineation in temperate forests is challenging owing to the presence of broadleaved species with overlapping crowns. Mixed coniferous/deciduous forests with characteristics that differ with the type of tree thus require a ...

Abyssal Solenogastres (Mollusca, Aplacophora) from the Northwest Pacific: Scratching the Surface of Deep-Sea Diversity Using Integrative Taxonomy

Frontiers in Marine Science, 2017
Solenogastres (Aplacophora) is a small clade of marine, shell-less worm-molluscs with close to 300 valid species. Their distribution ranges across all oceans, and whereas the vast majority of species has been collected and described from the continental ...

Species Discrimination within the Metarhizium PARB Clade: Ribosomal Intergenic Spacer (rIGS)-Based Diagnostic PCR and Single Marker Taxonomy

Journal of Fungi, 2023
(1) Background: The entomopathogenic fungus Metarhizium anisopliae sensu lato forms a species complex, comprising a tight cluster made up of four species, namely M. anisopliae sensu stricto, M. pinghaense, M. robertsii and M. brunneum.

The Impact of Spatial Delineation on the Assessment of Species Recovery Outcomes

Diversity, 2022
In 2021, the International Union for Conservation of Nature (IUCN) introduced a novel method for assessing species recovery and conservation impact: the IUCN Green Status of Species. The Green Status standardizes recovery using a metric called the Green Score, which ranges from 0% to 100%.

Using affinity propagation for identifying subspecies among clonal organisms: lessons from M. tuberculosis

BMC Bioinformatics, 2011
Background Classification and naming is a key step in the analysis, understanding and adequate management of living organisms. However, where to set limits between groups can be puzzling especially in clonal organisms.

Delineating generalized species boundaries from species distribution data and a species distribution model [PDF]

International Journal of Geographical Information Science, 2013
Species distribution models (SDM) are commonly used to provide information about species ranges or extents, and often are intended to represent the entire area of potential occupancy or suitable habitat in which individuals occur. While SDMs can provide results over various geographic extents, they normally operate within a grid and cannot delimit ...

Delineating species in the speciation continuum: A proposal [PDF]

Evolutionary Applications, 2019
AbstractDelineating species is a difficult and seemingly uninteresting issue that is still essential to address. Taxonomic methodology is heterogeneous according to the taxa and scientists involved due to the disparate data quality and quantity and disagreements over the species concept. This has negative impacts on basic and applied research.

Morphology Is Not a Reliable Tool for Delineating Species Within Cryptosporidium [PDF]

Journal of Parasitology, 2003
Within the coccidia, morphological features of the oocyst stage at the light microscope level have been used more than any other single characteristic to designate genus and species. The aim of this study was to conduct morphometric analysis on a range of Cryptosporidium spp.
