Los mamíferos de México en las colecciones científicas de Norteamérica

Abstract

Updated information on the geographic and taxonomic representativeness of mammal specimens deposited in 28 Mexican mammal collections, the Mammal Networked Information System (MaNIS), and the Unidad de Informática para la Biodiversidad (UNIBIO) data bases were compiled in order to analyze and compare the overall current status of the specimens of Mexican mammals deposited in collections in North America. A total of 421,466 specimens deposited in 120 collections were documented, of which 233,116 were deposited in collections in the United States of America and Canada, and 188,350 in collections in Mexico. The collections with the greatest number of specimens from Mexico are the Colección Nacional de Mamíferos (CNMA 46,000), the University of Kansas (KU 44,301), and the Escuela Nacional de Ciencias Biológicas (ENCB 43,985). In Mexican collections, the states of northern Mexico are improperly represented in number of specimens (< 3,000), whereas in foreign collections, the states of central Mexico are poorly represented. The Mexican states better represented by number of specimens (> 10,000) are Baja California Sur, Chiapas, Oaxaca, Puebla and Veracruz. The orders better represented in terms of number of specimens are Rodentia and Chiroptera (234,978 and 120,956, respectively). The Mexican states with the smallest area have the greatest density of specimens collected (specimens/km 2 ), such as Distrito Federal (3.2), Tlaxcala (1.4), Colima (1.06), and Morelos (0.9). The aim of this analysis is to provide a baseline to establish appropriate strategies to complete the Nota del editor.

Diversidad y distribución geográfica de los mamíferos terrestres del estado de Oaxaca, México

“…La colección con más ejemplares recolectados de México es la Colección Nacional de Mamíferos, seguida por la Universidad de Kansas y las Escuela Nacional de Ciencias, mientras que el American Museum of Natural History ocupa el séptimo lugar (Lorenzo et al, 2012). La colección científica con la mayor cantidad de ejemplares recolectados en Oaxaca es la Colección de Mamíferos del Centro Interdisciplinario de Investigación para el Desarrollo Integral Regional, Unidad Oaxaca, del Instituto Politécnico Nacional -Oaxaca, seguida por el American Museum of Natural History y la Colección Nacional de Mamíferos.…”

Retrieving Peromyscus bullatus from P. difficilis (Rodentia: Cricetidae) through cranial morphometry in a mammal collection

“…Even more, due to information deposited in collections has a greater scope and availability through digital platforms. Because of this, a routine review of the specimens to update or correct the information has been widely recommended (Lorenzo et al, 2012). Given our findings and the importance of having accurately designated specimens, we support a further search for P. bullatus among the P. difficilis specimens in collections, when they have been collected from the Oriental basin region in Mexico.…”

Mammal collections of the Western Hemisphere: a survey and directory of collections

“…The SCC survey was initiated in 2014 and continued with additions through March 2018; thus, data for accounts range from 6 months to 4 years old at the time of this publication. For collections that did not respond to information requests, their data were updated when possible through website information or literature ( Bezerra 2012 ; Lorenzo et al 2012 ). When no updated information could be located, data from the most recent survey responded to were retained and the source noted in the “Survey data” section (e.g., Hafner et al 1997 ; Yates et al 1987 ).…”
