Interspecific hybridization explains rapid gorget colour divergence in Heliodoxa hummingbirds (Aves: Trochilidae)
(The Royal Society, 2023-03-01)Hybridization is a known source of morphological, functional and communicative signal novelty in many organisms. Although diverse mechanisms of established novel ornamentation have been identified in natural populations, ... -
Technological and functional analysis of 80–60 ka bone wedges from Sibudu (KwaZulu-Natal, South Africa)
(Nature Research, 2022-09-29)Fully shaped, morphologically standardized bone tools are generally considered reliable indicators of the emergence of modern behavior. We report the discovery of 23 double-beveled bone tools from ~ 80,000–60,000-year-old ... -
Digital Extended Specimens: Enabling an Extensible Network of Biodiversity Data Records as Integrated Digital Objects on the Internet
(Oxford University Press, 2022-08-03)The early twenty-first century has witnessed massive expansions in availability and accessibility of digital data in virtually all domains of the biodiversity sciences. Led by an array of asynchronous digitization activities ... -
Basal Primatomorpha colonized Ellesmere Island (Arctic Canada) during the hyperthermal conditions of the early Eocene climatic optimum
(Public Library of Science, 2023-01-25)Anthropogenically induced warming is transforming Arctic ecosystems across a geologically short timescale, but earlier episodes of Earth history provide insights on the nature and limitations of biotic change in a rapidly ... -
Repeated evolution of blanched coloration in a lizard across independent white-sand habitats
(Wiley Open Access, 2022-12-07)The White Sands lizards of New Mexico are a rare and classic example of convergent evolution where three species have evolved blanched coloration on the white gypsum dunes. Until now, no geological replicate of the pattern ... -
Low risk of acquiring melioidosis from the environment in the continental United States
(Public Library of Science, 2022-07-29)Melioidosis is an underreported human disease of tropical and sub-tropical regions caused by the saprophyte Burkholderia pseudomallei. Although most global melioidosis cases are reported from tropical regions in Southeast ... -
A set of principles and practical suggestions for equitable fieldwork in biology
(National Academy of Sciences, 2022-08-16)Field biology is an area of research that involves working directly with living organisms in situ through a practice known as “fieldwork.” Conducting fieldwork often requires complex logistical planning within multiregional ... -
A New Subgenus and Species of Priochirus from Mid-Cretaceous Kachin Amber (Coleoptera: Staphylinidae: Osoriinae)
(MDPI, 2022-05-30)As one of the largest families of beetles (Coleoptera), the Staphylinidae (rove beetles and their relatives) are rich not only in extant species but also in a comparatively robust fossil record. Despite this preponderance ... -
Climate change influences on the geographic distributional potential of the spotted fever vectors Amblyomma maculatum and Dermacentor andersoni
(PeerJ, 2022-05-03)Amblyomma maculatum (Gulf Coast tick), and Dermacentor andersoni (Rocky Mountain wood tick) are two North American ticks that transmit spotted fevers associated Rickettsia. Amblyomma maculatum transmits Rickettsia parkeri ... -
A new genus of minute stingless bees from Southeast Asia (Hymenoptera, Apidae)
(Pensoft Publishers, 2022-03-16)A new genus of minute stingless bees (Meliponini: Hypotrigonina) is described from Southeast Asia. Ebaiotrigona Engel & Nguyen, gen. nov., is based on the type species Lisotrigonacarpenteri Engel, recorded from Vietnam, ... -
Bridging the Research Gap between Live Collections in Zoos and Preserved Collections in Natural History Museums
(Oxford University Press, 2022-04-21)Zoos and natural history museums are both collections-based institutions with important missions in biodiversity research and education. Animals in zoos are a repository and living record of the world's biodiversity, whereas ... -
Leptospirosis: Morbidity, mortality, and spatial distribution of hospitalized cases in Ecuador. A nationwide study 2000-2020
(Public Library of Science, 2022-05-12)Background In Ecuador, leptospirosis surveillance involves a mandatory notification of all cases and a hospitalization for severe illness. Morbidity and mortality are, nevertheless, underestimated and contribute directly ... -
Climatic refugia and reduced extinction correlate with underdispersion in mammals and birds in Africa
(Wiley Open Access, 2022-03-23)Macroevolutionary patterns, often inferred from metrics of community relatedness, are often used to ascertain major evolutionary processes shaping communities. These patterns have been shown to be informative of biogeographic ... -
Seasonal calibration of the end-cretaceous Chicxulub impact event
(Nature Research, 2021-12-08)The end-Cretaceous Chicxulub impact triggered Earth’s last mass-extinction, extinguishing ~ 75% of species diversity and facilitating a global ecological shift to mammal-dominated biomes. Temporal details of the impact ... -
The origins and spread of domestic horses from the Western Eurasian steppes
(Nature Research, 2021-10-20)Domestication of horses fundamentally transformed long-range mobility and warfare1. However, modern domesticated breeds do not descend from the earliest domestic horse lineage associated with archaeological evidence of ... -
Quantitative methods demonstrate that environment alone is an insufficient predictor of present-day language distributions in New Guinea
(Public Library of Science, 2020-10-07)Environmental parameters constrain the distributions of plant and animal species. A key question is to what extent does environment influence human behavior. Decreasing linguistic diversity from the equator towards the ... -
Leveraging natural history biorepositories as a global, decentralized, pathogen surveillance network
(Public Library of Science, 2021-06-03)The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic reveals a major gap in global biosecurity infrastructure: a lack of publicly available biological samples representative across space, time, and ... -
Phylogenomics Reveals Ancient Gene Tree Discordance in the Amphibian Tree of Life
(Oxford University Press, 2020-06-20)Molecular phylogenies have yielded strong support for many parts of the amphibian Tree of Life, but poor support for the resolution of deeper nodes, including relationships among families and orders. To clarify these ... -
Evidence of two deeply divergent co-existing mitochondrial genomes in the Tuatara reveals an extremely complex genomic organization
(Nature Research, 2021-01-29)Animal mitochondrial genomic polymorphism occurs as low-level mitochondrial heteroplasmy and deeply divergent co-existing molecules. The latter is rare, known only in bivalvian mollusks. Here we show two deeply divergent ... -
