In Colombia, amphibians are a vertebrate group with a high taxonomic richness, and an elevated representativity of species with restricted distributions. In recent years, regional collections have assisted to fill information gaps on the biogeography, intra- and interspecific variation, and systematics of the amphibians of the country. In this work we present the information of 1533 records deposited in the Amphibian Collection of the Museo de Historia Natural of the Universidad de Caldas, represented by 143 species, belonging to 49 genera and 19 families. Most of the records (n = 1194) come from the Department of Caldas, but there are records for 16 additional departments. The most representative order is Anura (n = 1487 records) followed by Caudata (n = 27 records), and Gymnophiona (n = 19 records). The collection houses 152 specimens that have been referenced in 13 national and foreign publications. [ABSTRACT FROM AUTHOR]

The Zoologische Staatssammlung Muenchen (ZSM), Germany, possesses an historical value because is the depositary of important specimens that were used in the description of different species, especially from South America. Unfortunately, there is not available information about the mammals of Colombia housed at this collection. For this, 33 specimens from Colombia belonging to six orders, 14 genus, and 17 species were reviewed. Cranial and external measurements are given, as well as information of collectors and localities. Of these specimens, 23 were captured in Northern Colombia and imported to Germany to a pet store between 1954 and 1966. Due the difficulties to access to information of mammals from Colombia in European museums and collections, the information summarized here may be useful for people interested in these species.

To consolidate the available information on terrestrial and marine mammals of the department of Nariño, voucher specimens from national collections as well as records from international museum databases and the scientific literature were investigated. A checklist of 182 mammalian species is presented. Out of those, 24 species are considered as threatened under some category in Colombia. Our work reveals the need of new efforts to fill out the mammalian information gaps for this portion of the country. [ABSTRACT FROM AUTHOR]

Due to its high number of ecosystems and wide altitudinal gradient, the department of Cauca in southwestern Colombia, encloses a great part of the Colombian mammal diversity. In spite of its richness, the mammalian fauna from Cauca has been poorly studied. In order to synthesize the information on mammals from this Department, we present a checklist of 220 mammalian species that occupy the continental and marine area of Cauca, representing 45% of mammals reported as present or potentially present in Colombia. The present work was based on national mammal collections, international museums databases, and bibliographic information. Although this work represents the most comprehensive effort in documenting the mammalian fauna of the department of Cauca, future research is necessary to increase our knowledge on the mammals of Cauca and to implement more adequate conservation policies.

We describe the advertisement call of seven males and observations on the natural history related to the parental attention by males, of a population of nurse frogs attributed to the Leucostethus fraterdanieli complex from the Central Cordillera in the Department of Caldas, Colombia. The advertisement call consists of a long sequence of repeated (x2 = 143 notes.min-1) pulsed notes, which have an average duration of 79 ± 17 ms (range 63-122 ms), separated by time intervals between 187-413 ms (289 ± 67 ms). The dominant frequency values are in the range between 3209-3520 Hz. Our results suggest differences in temporal and spectral parameters between the population studied and other populations assigned to L. fraterdanieli, L. brachistriatus, and the recently described L. jota.

In Colombia, records of fishes of the family Loricariidae transplanted in different freshwater systems are unknown. In this work, the history of the transplant of the loricariid Pterygoplichthys undecimalis, that is naturally distributed in several rivers different rivers that drain to the Caribbean of Colombia, into the upper Patía River Basin, that drains to the Pacific is described. Our observations show that the species has been successfully established in different tributaries of the Patía River, with the first records during 2006 and the most recent records in 2016.

The Caquetá titi monkey, Plecturocebus caquetensis (Primates: Pitheciidae), is endemic to the Amazon foothills in the departments of Caquetá and Cauca, Colombia. Being a species recently described, the information on its distribution and natural history is still scarce. We present a distribution update and observations on its natural history and ecological relationships in the Department of Cauca. We obtained 129 occurrences in Caquetá (n=75) and Cauca (n=54), 51 and 31 of them, respectively, representing new records for each department. The extension of occurrence (EOO) and area of occupancy (AOO) were 3741 km² and 196 km², respectively. Among the natural history observations, P. caquetensis occurred mainly in the edges of seasonally flooded forests with bamboo plants (Guadua sp.). The diurnal behavior included vocalization, locomotion, rest, play and feed. Ecological relationships of the species with birds, reptiles and mammals includes predation events by boas and birds. Furthermore, ecological observations about the consumption of bamboo petioles and the use of Vochisia sp. trees as nesting site is provided. We suggest exploring the presence of P. caquetensis in the "Serranía de los Churumbelos Auka-Wasi" protected area and the creation of conservation plans with the communities inhabiting the distribution area.
