TLDR
The Guanacevi region has been actively mined at least for the last 500 years and mining activity has resulted in a large number of abandoned mines, which may represent important refuges for the chiropteran fauna of the region as mentioned in this paper.Abstract:
The Guanacevi region has been actively mined at least for the last 500 years. Mining activity has resulted in a large number of abandoned mines, which may represent important refuges for the chiropteran fauna of the region. I surveyed a sample of 25 abandoned mines during an annual cycle to determine which species use the mines, how they use it, and whether occupation is significantly related to a set of environmental variables measured from the mines. Simultaneously I carried out an inventory of the chiropteran fauna in the area, to determine what portion of the assemblage use the mines. I recorded 13 species for the region (12 vespertilionids and 1 molossid), out of 18 that are likely to occur. Five species were never found in mines; the remaining use them as feeding roosts, temporary roosts, or hibernacula, and only Corynorhinus mexicanus was found forming a maternity colony. Bats were significantly (P 50 m, and less than 3...read more

Cave-Dwelling Arthropods and Vertebrates of North Rim Grand Canyon, with Notes on Ecology and Management
J. Judson Wynne,Kyle D. Voyles +1 more
TL;DR: Future directions for conservation and management for caves on Grand Canyon—Parashant National Monument, northwestern Arizona are provided based on invertebrate and vertebrate inventory work conducted during 2005 and 2006 and the lack of cave-adapted arthropods is considered of high management concern.

Geochemical variations of core sediments of Pichavaram Lagoon, southeast coast of Tamil Nadu, India: a provenance and paleoenvironmental study
TL;DR: The Pichavaram mangrove is a dynamic intertidal environment lying in between the Vellar and Coleroon estuaries in the Cauvery delta along the east coast of India as discussed by the authors.

Inventory, Features, and Protection of Underground Roosts Used by Bats in Mexico
TL;DR: In this paper, the authors conducted a search for information on caves, mines, tunnels, and culverts used as roosts by bats in Mexico, in order to create an inventory and a database, as well as a list of priority sites for their protection.

A checklist of the mammals (Mammalia) from Durango, western Mexico
TL;DR: An updated list of the mammals of Durango state, Mexico was built from literature records and Museum specimens, and a total of 139 species have been recorded, representing 28.3 % of the Mexican terrestrial mammals, and 25.1 % species more compared to the previous account.

Abandoned Mines Used as Roosts for Reproduction by Townsend’s Big-Eared Bats (Corynorhinus townsendii) in a Protected Area in the Central Highlands of Mexico
León-Galván Miguel Angel,Rodríguez-Tobón Ahiezer,Cano Espinoza José Sulim,Guzman Ledesma Beatriz Samantha,Guevara-Chumacero Luis Manuel,Leyequien Abarca Lissette +5 more
TL;DR: M Monitoring the potential roosts by Corynorhinus townsendii was made within the system of mines in the vicinity of the Sierra La Mojonera Flora and Fauna Protection Area, at Mexico’s Central Highlands, confirming that C. townsendII in the area of study follow a seasonally monoestrous reproductive pattern, characterized by an asynchrony between the ovarian and spermatogenic cycles.

Physiological and ecological aspects of roost selection by reproductive female hoary bats (lasiurus cinereus)
TL;DR: The results provide direct evidence that hoary bats select forest roosts on the basis of microclimate and suggest that roost requirements of foliage-roosting species may be more specific than has been previously assumed.

Conservation Biology of the Cave Bats of Mexico
TL;DR: A conservation plan based solely on diversity is not adequate for the protection of cave bats in Mexico because few of the fragile and vulnerable species of Mexican bats roost in caves with high species richness or with large populations.

Ecological, Taxonomic, and Physiological Correlates of Cave Use by Mexican Bats
TL;DR: The hypothesis that temperature is the most important physical factor influencing roost selection in bats support the hypothesis that the thermoregulatory ability resulting from the complex interaction of body size, type of food, and taxonomic affiliation constrains species with respect to types of roosts that they can successfully exploit.
