Eptesicus diminutus Osgood, 1915 is the smallest species of the subgenus Eptesicus found in South America. It has a discontinuous distribution, with northern populations in Colombia and Venezuela, and southern populations in Argentina, Brazil, Paraguay, and Uruguay. We reviewed specimens assigned to the northern populations of E. diminutus and compared them to these from the southern populations. Based on morphologic, morphometric, and molecular analyses, we support the recognition of the northern ...

Abstract The genus Molossops includes two species that are restricted to South America: Molossops neglectus and Molossops temminckii . The smaller dog-faced dwarf Molossops temminckii is distributed from Colombia to Argentina and has a wide morphological variation and vocal plasticity. In Colombia, this species remains poorly known. To fill distributional gaps, we present novel records from Arauca, Atlántico, Bolívar, Córdoba, and Huila departments. We also present an analysis of the morphometric ...

In Colombia, seven species of small-eared shrews of the genus Cryptotis Pomel, 1848 have been reported, and five of them endemic to the country. Here, we present the first confirmed record from Colombia of Cryptotis niausa Moreno Cárdenas & Albuja, 2014, a species that was previously known from only nine localities in Ecuador. The Colombian record comes from the Departamento de Nariño, in extreme southwestern Colombia, and it is supported by morphology and cytochrome- b ...

Gynandromorphism is a condition in which an organism exhibits both male and female characters simultaneously. This condition is the result of an abnormal process during embryonic development, and has been frequently reported in arthropods, especially crustaceans, insects, and arachnids. Here, we report a case of gynandromorphism in the brown dog tick, Rhipicephalus sanguineus s.l. in Colombia. The individual was collected from a domestic dog in the municipality of Samaná, Department of Caldas, in ...

The study of host-parasite interactions is key to understanding ecological interactions since parasites play a crucial role in the regulation of populations of host species. The families Nycteribiidae and Streblidae (Diptera: Hippoboscoidea) are ectoparasitic flies specific to bats, which have evolved adaptations to their host. The host-parasite interactions are formed by coevolutionary processes and illustrate the current and historical associations between the species involved. For this reason, ...

Following the injection of Plasmodium sporozoites by a female Anopheles mosquito into the dermis, they become engaged on a long journey to hepatic tissue where they must migrate through different types of cell to become established in parasitophorous vacuoles in hepatocytes. Studies have shown that proteins such as cell traversal protein for Plasmodium ookinetes and sporozoites (CelTOS) play a crucial role in cell-traversal ability. Although CelTOS has been extensively studied in various species ...

Studies on public health and wild mammal biodiversity include a genetic component. For blood samples, there must be optimal sample collection conditions since these can affect DNA preservation and extraction. This study evaluated the use of liquid and dry DNA preservation methods and commercial and non-commercial DNA extraction methods on field-collected blood samples. For this, 264 total blood samples were collected from wild mammals. A first group of samples was preserved in guanidine hydrochloride ( ...

Esta aventura en busca de sentidos, que se lanza hacia el encuentro del otro, permitió develar las dimensiones de la alteridad que se tejen en una red de sentidos y proyecciones hacia la formación humana. Dicha red se halla como la tensión entre el otro visto como instrumento y su reconocimiento en el proceso formativo, en una trama compleja en la que conviven la condición humana y pedagógica con todas sus expresiones.

Abstract It is widely accepted that accumulation of greenhouse gases in the atmosphere, including methane (CH4), is promoting climate change. Cattle contribute significantly to CH4 emissions, mainly generated during ruminal fermentation. Measuring CH4 emissions is expensive and time-consuming, hampering individual, constant, and scalable monitoring at the farm level. Thus, developing innovative methodologies to measure CH4 emissions from cattle is crucial. These methodologies should enable the identification ...

The family Polyctenidae (Cimicoidea: Hemiptera) is a group of ectoparasites that has received very little attention from researchers. These bugs are typically associated with bats and are found primarily in tropical and subtropical regions worldwide. Polyctenidae consist of 32 species, which are divided into two subfamilies (Polycteninae and Hesperocteninae) and five genera (Adroctenes, Eoctenes, Hypoctenes, and Polyctenes within Polycteninae and Hesperoctenes within Hesperocteninae). The genus Hesperoctenes ...

Introduction: Due to the emergence of the SARS-CoV-2 coronavirus since December 2019, a large volume of scientific production has been generated, in some cases uncertain or controversial, especially in the pharmacological management of patients with this infection; therefore, it is considered a relevant search for methodological alternatives to carry out its rigorous, systematic and quality synthesis, but with less execution time and lower cost. Objective: To present the available evidence regarding ...
