This database compiles comprehensive occurrence information based on voucher specimens of small-eared shrews, genus Cryptotis, that occur from México to Peru. The database integrates the information obtained from four main sources: natural history museums, public databases, fieldwork, and scientific literature. It contains 3,639 records from 53 species in 12 countries. It aims to be a valuable resource for students, researchers, conservationists, and decision-makers.

研究區域描述 |
The dataset contains records on 53 species of Cryptotis found in the territory from Mexico to Peru. The only species of the genus not included is Cryptotis parvus, which is of Nearctic affinity and distributed in the United States and Canada. |
研究設計描述 |
Shrews (Eulipotyphla, Soricidae) play an essential role in the structure and dynamics of populations of invertebrates, such as beetles, spiders, and earthworms, of which they feed voraciously. These small mammals are found in habitats throughout most of the planet but prefer humid tropical and temperate environments. Despite the high diversity and wide distribution of shrews, research on the natural history, taxonomy, systematics, distribution, and ecology is still surprisingly patchy. Recent large-scale reviews suggest that basic research on shrew species is urgently needed, particularly in tropical regions where they may be at serious risk of extinction due to combined pressures of land-use change and climate change. Small-eared shrews of the genus Cryptotis are the third most diverse among the 29 genera that comprise the entire family (Database 2024). In less than 20 years, the number of species in the genus has increased from 30 to 54. This number is expected to grow due to increased taxonomic work on the group, fieldwork, and the recent obtaining of genetic data. The genus is distributed from southern Canada to northern South America, with a remarkable species increase towards Central Mexico and Guatemala. In this region, the small-eared shrews have reached their greatest diversity and distribution, mainly restricted to mountain ecosystems characterized by cold and moist forests. The growing research activity around the genus in the Neotropics has caused taxonomic and nomenclatural changes and increased information on species' presence in previously unexplored regions and on poorly known taxa. Now, we have integrated a curated database of 3,678 voucher specimens of the 53 small-eared shrews found in this region by combining previously published records on digital databases, new data from fieldwork, scientific literature, and the revision of specimens in natural history museums. |
參與計畫的人員:
Occurrence data were obtained from four primary sources (see Step description). For scientific collecting, we combined Sherman traps and pitfall traps. The localities were georeferenced in the field using global positioning systems. All scientific collecting was conducted under permits issued by the Mexican Government and prior authorization from the local authorities. We followed standard recommendations on specimen capture, sacrifice, and preparation of small mammals (Sikes et al., 2016).

All original records were curated to confirm species identification and verify temporal and spatial congruence. We eliminated duplicates and records in which it was impossible to verify the specimen's catalog number. The final species list was checked using the Mammal Diversity Database (Version 1.7). Valid names were carefully reviewed and following the International Code of Zoological Nomenclature. The collection date was separated into day, month, and year. The locality for each record was also scrutinized to check its congruence with the distribution of the species according to the literature examined. The decimal degrees georeferenced of the records were verified or obtained using Google Earth Pro 7.3.6.9796. Ambiguous localities or locations with insufficient information were kept without assigned georeferenced. |
方法步驟描述:
-
Step one: Data collection. Specimen records were obtained from four main sources: natural history museums, public online databases, literature, and fieldwork. a) Natural History Museums: We reviewed specimens in the following 21 scientific collections from Colombia, Ecuador, México, and the United States: Quito, Ecuador). Fluid bodies, skins, skulls, and/or postcranial skeletons were reviewed to corroborate or determine the taxonomic identity and obtain or verify the collecting data and sex of specimens. b) Public online databases: We consulted data in public databases of the following scientific collections that house specimens of shrews from the Neotropical region: American Museum of Natural History (AMNH); National Museum of Natural History, Smithsonian Institution (USNM), The University of Kansas, Natural History Museum (KU), British Museum of Natural History (BMNH); Instituto de Investigación de Recursos Biológicos Alexander von Humboldt (IAvH-M). We also consulted the Arctos online collection management information system, the database related to the project “Modelado de la distribución potencial de las musarañas (Mammalia, Soricidae)” from the Comisión Nacional para el Conocimiento y Uso de la Biodiversidad, and the DataWebEcuador, a portal to access data of specimens from the collections of Ecuador. We also compare the information with what is available in Global Biodiversity Information Facility through a download on 8 April 2024 (https://doi.org/10.15468/dl.qtdnkn). c) Literature: We carefully reviewed the most recent literature to incorporate taxonomic and nomenclatural changes to the database. Additionally, we include new records that have not yet been digitized or are not still available in any database. d) Fieldwork: We carried out fieldwork aimed at the scientific collecting of shrews in nine states of Mexico: Chiapas, Colima, Estado de México, Hidalgo, Oaxaca, Puebla, San Luis Potosí, Tamaulipas, and Veracruz. Step two: Data integration. As mentioned in the Design Description sub-section, the taxonomy and nomenclature of small-eared shrews have changed intensively over the last two decades. Hence, the synonymy used by each researcher to identify the original work or identification was preserved. The taxonomic lists of the Mammal Diversity Database (Version 1.7) and Woodman (2019) were used as the base to unify the nomenclature. A combination of .csv and .dbf files was initially used to compile and curate the records. All data were migrated into a database following the Darwin Core Standard containing 36 column labels.
