Species are defined using a variety of different operational techniques. While discussion of the various methodologies has previously been restricted mostly to taxonomists, the demarcation of species is also crucial for conservation biology. Unfortunately, different methods of diagnosing species can arrive at different entities. Most prominently, it is widely thought that use of a phylogenetic species concept may lead to recognition of a far greater number of much less inclusive units. As a… 
The implications of different species concepts for describing biodiversity patterns and assessing conservation needs for African birds
TLDR
The large-scale biogeographic patterns are robust to changes in species concepts, and reflects the aggregated nature of endemism, with certain areas acting as “species pumps” and large intervening areas being characterised by a predominance of widespread species which distribute themselves in accordance with contemporary environmental conditions.
Are Species Good Units for Biodiversity Studies and Conservation Efforts?

While species have long been seen as the principal units of biodiversity, with prominent roles in biodiversity research and conservation practice, the long-standing debate on the nature of species
The application of species criteria in avian taxonomy and its implications for the debate over species concepts

TLDR
There is a discrepancy between widely held perceptions of how species are delimited and the way species are actually delimited by taxonomists, and no support was found for the idea that Phylogenetic Species Concepts have caused a change in the ‘nature’ of species taxa.
Implications of different species concepts for conserving biodiversity
The role of taxonomy in species conservation.

Taxonomy and species conservation are often assumed to be completely interdependent activities. However, a shortage of taxonomic information and skills, and confusion over where the limits to
Taxonomic Delimitation of Species Complexes: A Challenge for Conservation; First Steps with the Abarema cochliacarpos Complex
TLDR
The level of morphometric variation within the Abarema cochliacarpos complex throughout its entire distribution range in the Brazilian Atlantic Forest and Caatinga vegetation is investigated, and the drivers of this variation are considered.
Which Species Should We Focus On? Umbrella Species Assessment in Southwest China
TLDR
This study assessed 810 key protected species from seven taxa by indicator value analysis, correlation analysis, and factor analysis, selecting 32 species as umbrella species, whose habitats overlapped the habitats of 97% of the total species.
An analysis of species boundaries and biogeographic patterns in a cryptic species complex: the rotifer--Brachionus plicatilis.
Quantitative criteria for species delimitation
TLDR
This work develops quantitative methods for a classic technique in systematic zoology, namely the use of divergence between undisputed sympatric species as a yardstick for assessing the taxonomic status of allopatric forms, which can be applied to the global avifauna to deliver taxonomic decisions with a high level of objectivity, consistency and transparency.
Phylogenetic biodiversity assessment based on systematic nomenclature
TLDR
The results support that species, genus and site numbers predict evolutionary history, to a degree depending on the size of the data set, as well as providing a proof-of-concept for assessing conservation schemes for systematized but un-phylogenised taxa spread over a series of sites.

TLDR
In groups with extensive dispersal ability, there may be predictable relationships between genetic and reproductive divergence that allow taxonomic decisions to be made using either species concept, although evidence for this in the field is limited.

: Although conservation biologists base most of their activities on species taxa, they have participated little in the debate of systematists and evolutionary biologists about the recognition and
Molecular Systematics and the Conservation of Rare Species
TLDR
This appeal to systematists to contribute actively to both conservation theory and practice is appealed to, and the integration of systematics is called for in the establishment of conservation priorities and the development of strategies to preserve Earth’s biota.
Conservation and species lists: taxonomic neglect promotes the extinction of endemic birds, as exemplified by taxa from eastern Atlantic islands

TLDR
Some examples of endemic taxa from eastern Atlantic islands are discussed, demonstrating the way “list thinking” and the lack of phylogenetic reasoning among conservationists translates into the presence or absence of conservation actions.
Testing Species Boundaries in Biodiversity Studies
TLDR
This paper suggests that this paper is fundamentally flawed because it fails to present any species concept as a testable hypothesis, and recommends the following procedures for implementation of lineage-based species concepts within a rigorous hypothesis testing framework.
Molecular approaches and the concept of species and species complexes in lichenized fungi
TLDR
The concept of species and species complexes of lichenized fungi is reviewed in the light of recent molecular approaches and molecular analyses at the species level will lead to the re-evaluation of phenotypic characters for species delimitation, and will improve the understanding of speciation in lichenization fungi.
A Critique of the Biological Species Concept and Recommendations for a Phylogenetic Alternative
TLDR
The biological concept fails to provide unambiguous criteria for grouping organisms (or for assigning species rank), and as a consequence, biological species may not be monophyletic.
