Accurate taxonomy is central to the study of biological diversity, as it provides needed evolutionary framework for taxon sampling and interpreting results. While number recognized species in class Mammalia has increased through time, tabulation those increases relied on sporadic release revisionary compendia like Mammal Species World (MSW) series. Here, we present Diversity Database (MDD), a digital, publically accessible, updateable list all mammalian species, now available online:...
Specimens and associated data in natural history collections (NHCs) foster substantial scientific progress. In this paper, we explore recent contributions of NHCs to the study systematics biogeography, genomics, morphology, stable isotope ecology, parasites pathogens mammals. To begin assess magnitude scope these contributions, analyzed publications Journal Mammalogy over last decade, as well research supported by a single university mammal collection (Museum Southwestern Biology, Division...
The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic reveals a major gap in global biosecurity infrastructure: lack of publicly available biological samples representative across space, time, and taxonomic diversity. shortfall, this case for vertebrates, prevents accurate rapid identification monitoring emerging pathogens their reservoir host(s) precludes extended investigation ecological, evolutionary, environmental associations that lead to human infection or...
Natural history museums are vital repositories of specimens, samples and data that inform about the natural world; this Formal Comment revisits a Perspective advocated for adoption compassionate collection practices, querying whether it will ever be possible to completely do away with whole animal specimen collection.
The Beringian Coevolution Project (BCP), a field program underway in the high northern latitudes since 1999, has focused on building key scientific infrastructure for integrated specimen-based studies mammals and their associated parasites. BCP contributed new insights across temporal spatial scales into how ancient climate environmental change have shaped faunas, emphasizing processes of assembly, persistence, diversification vast region. collections also represent baseline records biotic...
Abstract Hybridization provides a window into the speciation process and reshuffles parental alleles to produce novel recombinant genotypes. The presence or absence of specific hybrid classes across zone can provide support for various modes reproductive isolation. Early generation be distinguished by their combination index interclass heterozygosity, which estimated with molecular data. Hybrid heterozygosity are routinely calculated studies zones, but available resources next-generation...
Abstract Organisms that live in deserts offer the opportunity to investigate how species adapt environmental conditions are lethal most plants and animals. In hot of North America, high temperatures lack water conspicuous challenges for organisms living there. The cactus mouse ( Peromyscus eremicus ) displays several adaptations these conditions, including low metabolic rate, heat tolerance, ability maintain homeostasis under extreme dehydration. To genomic basis desert adaptation mice, we...
Abstract The open-science movement seeks to increase transparency, reproducibility, and access scientific data. As primary data, preserved biological specimens represent records of global biodiversity critical research, conservation, national security, public health. However, a recent decrease in specimen preservation biorepositories is major barrier open science. such, there an urgent need for cultural shift the life sciences that normalizes deposition museum collections. Museums embody...
Abstract The Convention on Biological Diversity and the Nagoya Protocol Access Benefit-Sharing provide an international legal framework that aims to prevent misappropriation of genetic resources a country ensure fair equitable sharing benefits arising from their use. legislation was negotiated at behest lower-income, biodiverse countries derived research development within jurisdictions were equitably returned could thereby incentivize conservation sustainable use biodiversity. Despite good...
ABSTRACT Describing naturally occurring genetic variation is a fundamental goal of molecular phylogeography and population genetics. Popular methods for this task include STRUCTURE , model‐based algorithm that assigns individuals to clusters, principal component analysis (PCA), parameter‐free method. The ability infer mixed ancestry makes it popular documenting natural hybridisation, which considerable interest evolutionary biologists, given such systems provide window into the speciation...
At high latitudes, climatic shifts hypothetically initiate recurrent episodes of divergence by isolating populations in glacial refugia-ice-free regions that enable terrestrial species persistence. Upon recession, subsequently expand and often come into contact with other independently diverging populations, resulting gene flow. To understand how periods isolation may have impacted evolution at we investigated introgression dynamics the stoat (Mustela erminea), a Holarctic mammalian...

Abstract Availability of food resources is an important driver survival. Populations must either relocate or adapt to persist in environments where availability changing. An optimal diet balances energy gain, water regulation, and nutrition. We used flow-through respirometry characterize metabolic phenotypes the desert-adapted Cactus Mouse (Peromyscus eremicus) under diurnally variable environmental conditions that mimic Sonoran Desert. treated mice with 2 different energetically equivalent...

Abstract Freezing has proven to be an ideal means for preserving tissues molecular research on mammals. Here, we trace the origins, early practices, and rapid growth of frozen tissue collections better understand history, science, people that led development recent these internationally valuable resources. Frozen grew gradually from rudimentary beginnings in 1970s but have expanded rapidly years, providing data studies biodiversity, phylogenetics, emerging pathogens, isotopes, contaminants,...
Contemporary climate change is rapidly affecting species’ ranges and distributions. While there a general trend of poleward movement, are exceptions. For example, despite the North American least weasel’s ( Mustela nivalis ) elusive nature, mammalogists in mid-1900s noted potential southward extension its range into central US, opposite paradigm. Historically, record species new location was sufficient for documenting expansion; yet, such observations can be biased by extent regional...
Effective conservation of insular populations requires careful consideration biogeography, including colonization histories and patterns endemism. Across the Pacific Northwest North America, martens (Martes caurina) American pine americana) are parapatric sister species with distinctive postglacial histories. Using mitochondrial DNA 12 nuclear microsatellite loci, we examine processes island anthropogenic introductions across 25 martens. Along Coast (NPC), M. caurina is now found on only 2...
Abstract Warming climate and increasing desertification urge the identification of genes involved in heat dehydration tolerance to better inform target biodiversity conservation efforts. Comparisons among extant desert-adapted species can highlight parallel or convergent patterns genome evolution through shared signatures selection. We generate a chromosome-level assembly for canyon mouse (Peromyscus crinitus) test signature by comparing selective sweeps across population-level genomic...
Abstract Aim Refugial isolation during glaciation is an established driver of speciation; however, the opposing role interglacial population expansion, secondary contact, and gene flow on diversification process remains less understood. The consequences glacial cycling diversity are complex especially so for archipelago species, which experience dramatic fluctuations in connectivity response to both lower sea levels events increased fragmentation recession. We test whether extended refugial...
The Costa Rican pygmy rice rat (Oligoryzomys costaricensis) is the primary reservoir of Choclo orthohantavirus (CHOV), causal agent hantavirus disease, pulmonary syndrome, and fever in humans Panama. Since emergence CHOV early 2000, we have systematically sampled archived rodents from >150 sites across Panama to establish a baseline understanding host virus, producing permanent archive holistic specimens that are now probing greater detail. We summarize these collections explore...
High-throughput sequencing technologies are a proposed solution for accessing the molecular data in historical specimens. However, degraded DNA combined with computational demands of short-read assemblies has posed significant laboratory and bioinformatics challenges de novo genome assembly. Linked-read or "synthetic long-read" technologies, such as 10× Genomics, may provide cost-effective alternative to assemble higher quality genomes from tissue samples. Here, we compare assembly (e.g.,...
