Accurate taxonomy is central to the study of biological diversity, as it provides the needed evolutionary framework for taxon sampling and interpreting results. While the number of recognized species in the class Mammalia has increased through time, tabulation of those increases has relied on the sporadic release of revisionary compendia like the Mammal Species of the World (MSW) series. Here, we present the Mammal Diversity Database (MDD), a digital, publically accessible, and updateable list… 

Rodent systematics in an age of discovery: recent advances and prospects

An overview of changes in the understanding of the systematics of living rodents, including species recognition and delimitation, phylogenetics, and classification, with emphasis on the last three decades is provided.

The role and impact of Zootaxa in mammalogy in its first 20 years.

It is found that Zootaxa has had a significant contribution to mammalogy, being the second journal in terms of number of new species described, and the majority of the new species were described following an integrative taxonomic approach with at least two sources of data.

Updated and annotated checklist of recent mammals from Brazil.

An updated and annotated checklist of mammals occurring in Brazil is presented, finding that 15 new species were described since the last national compilation (published in 2017), which associated to new records to the country and synonimizations resulted in an increment of 30 species.

Genetic and morphological diversity of mouse lemurs (Microcebus spp.) in northern Madagascar: The discovery of a putative new species?

It is shown that the spatial distribution of forest‐dwelling species may be used as a proxy to reconstruct the past spatial changes in forest cover and vegetation type, and a significant correlation between climatic variables and morphology is suggested, suggesting a possible relationship between species identity, morphology, and environment.

Undescribed species have higher extinction risk than known species

Testing how time since formal description of a species is linked to its threat status to obtain a better insight into the possible threat status of newly described species and as yet undescribed species finds that current species extinction rates are highly likely to be underestimated.

Lagomorpha as a Model Morphological System

It is shown that lagomorphs are a strong system in which to study macro- and micro-scale patterns of morphological change within a clade that offers underappreciated levels of diversity.

On the distinction and availability of the new taxa proposed by Agnolin et al. 2019

Recently, Agnolin et al. (2019) described 14 new species of mammals, including 12 rodents, one bat, and one carnivore, and one new subspecies of rodent. In addition, these authors proposed several

Lista actualizada y comentada de los mamíferos de Bolivia

The list of mammals known to occur in Bolivia includes 406 native species, belonging to 11 orders, 46 families and 196 genera, representing an increase of 51 species over the 2003 list, and 14 species of introduced mammals are listed.

Conservation Genetics of Rodents in Argentina

This work capitalize on recent efforts to establish the conservation status of mammals in Argentina and combine this information with available molecular genetic data for rodents in this country, a diverse assemblage of some 200 species.

Systematics of Brucepattersonius Hershkovitz, 1998 (Rodentia, Sigmodontinae): molecular species delimitation and morphological analyses suggest an overestimation in species diversity

This study presents a phylogenetic hypothesis including samples throughout the distribution of the genus Brucepattersonius and employed single-locus molecular species delimitation analyses to provide a new hypothesis for species limits within Brucepat Pattersonius, and recovers four strongly supported clades within the genus.

Mammal species of the world: a taxonomic and geographic reference

The format of accounts in this edition is similar to the previous volume, with the order Rodentia deserving a more detailed revision through subordinal division, and this arrangement seems to be well accepted by the scientific community.

Global trends and biases in new mammal species discoveries.

An analysis of patterns of discovery suggests that complete alpha-taxonomic characterization of living mammals remains a far-off goal, and an analysis of 341 recently described species indicates that the great majority of them are restricted to threatened areas of high endemism.

Nomenclature and placental mammal phylogeny

It is concluded that no matter how reconstructions of the Tree of Life change in years to come, systematists should apply new names reluctantly, deferring to those already published and maximizing consistency with existing nomenclature.

Taxonomy of Australian Mammals

This book lays a foundation for future taxonomic work and identifies areas where taxonomic studies should be targeted, not only at the species and subspecies level but also broader phylogenetic relationships.

By analysing nomenclature for Neotropical mammals, two well-defined biases are documented that are associated with species accumulation: definite trends in body size are evident, so that larger organisms were more quickly apparent to systematists.
