Plants traditionally used for their antiviral activity could be an alternative against SARS-CoV-2. In this study, the efficacy of 10 bioactive plant compounds commonly used in Mexico against COVID-19 was evaluated by molecular docking with two online servers: COVID-19 Docking Server and DockThor. Remdesivir was used as a control. The results showed...
Drylands are ecosystems whose biodiversity has developed the ability to adapt to extreme conditions, such as scarcity of water and high temperatures, and has evolved to survive in an environment where biomass and energy flow are limited. Microorganisms are a fundamental part of biodiversity in drylands since they have ecological and functional inte...
In the present study, we characterized species of bacteria and fungi across a frog community in a seasonal tropical environment in the Natural Protected Area (NPA) Las Musas, Guanajuato, Mexico, using morphological and biochemical protocols. Our three main objectives were to: i) identify the species of microorganisms present in the frog community,...
Yerba mate (Ilex paraguariensis A.St. Hil) and jarilla (Larrea divaricata Cav.) leaves are commonly used as tea infusions in some Latin American countries. This study was conducted to evaluate the antioxidant activity (FRAP, ABTS, and DPPH) and the inhibitory potential of yerba mate and jarilla extracts on the 3CL protease (Mpro) from coronavirus S...
This study is the first record of medicinal plants in the southwest of the Coahuila state, an arid zone where extreme dry conditions prevail. One hundred twenty-two residents (in sixteen communities) were interviewed. The residents were questioned with a questionnaire-guided ethnomedical survey protocol about the various plants used. Seventy-seven...
The objective of the present study was to estimate the prevalence of parasites and identify the ones with the zoonotic potential present in the feces of households dogs and stray dogs in Gomez Palacio, Durango, Mexico. Fifty fecal samples from household dogs and 50 fecal samples from stray dogs were collected and analyzed by sucrose flotation and M...
Los anfibios son el grupo de vertebrados más amenazado en la actualidad. Entre los
factores que han propiciado el declive y extinción de algunas poblaciones y
especies de anfibios está la contaminación por metales pesados. Debido a
procesos industriales y mineros, metales pesados como el plomo y hierro son
arrojados al ambiente, llegando así a los...
La generación de conocimiento y productos académicos es el reflejo de la calidad de los investigadores e instituciones. Sin embargo, debido al alto número de doctores egresados de los programas de doctorado y, a la limitada disponibilidad de plazas académicas en instituciones públicas y privadas, además de la falta de condiciones adecuadas para la...

Abstract:
The present study evaluated the efficacy of the main bioactive compounds present in plants of the Mexican semi-desert (Flourensia cernua, Larrea tridentata, and Lippia graveolens) against COVID-19 protease (Mpro) and replicase (RdRp) by molecular docking study (In silico). The results show that Luteolin 7-O-glucoside (L. graveolens) has...
In this study, concentrations of heavy metals (Ni, Cd, Pb, Cr, and Zn) were determined in water, sediment and tissues (intestine, gills and liver) of the anuran amphibian Dryophytes plicatus (tadpoles) from a lake in Mineral El Chico, Hidalgo, Mexico. The metal concentrations were obtained by spectrochemical analysis. Results showed that in water,...
As climate change marches on, rapidly rising temperatures shatter records every year, presenting ever-growing physiological challenges to organisms worldwide. Ectotherms rely on behavioral and physiological plasticity to contend with environmental fluctuations. Nonetheless, our understanding of thermal plasticity has been largely limited to laborat...
The effects of bioregulators purified from mammalian blood serum and bone tissue on amphibian limb regeneration have been studied. The bioregulators from blood serum at a high concentration (10-1 mg/mL) has a strong morphogenetic effect on Xenopus laevis limb regeneration following amputation through the proximal part of the femur and a protective...
We present an updated checklist of native Mexican freshwater gastropods with data on their general distribution,
hotspots of endemicity, threats, and for the first time, their estimated conservation status. The list contains 193 species,
representing 13 families and 61 genera. Of these, 103 species (53.4%) and 12 genera are endemic to Mexico, and 7...
A bioindicator is an organism sensitive to environmental changes and, therefore, its absence or scarcity indicates that there is some factor that is modifying the normal conditions of the environment. Amphibians are excellent bioindicators for several reasons: they are sensitive to contaminants such as heavy metals or pesticides, being a good model...
The decline of freshwater species diversity is
a worldwide phenomenon but it is especially
pronounced in arid regions such as in the
Chihuahuan Desert of Coahuila and Durango,
Northern Mexico. There are few historical data
on the distribution but no data on extinctions
of Mexican freshwater gastropods. In such
cases, paleontological data can be ver...

Los anfibios anuros son animales vertebrados que tienen un proceso de metamorfosis y que pasan una parte de su vida en el agua y otra en la tierra, en tierra, la mayoría permanecen cerca de zonas húmedas, no obstante, algunas especies se han adaptado a vivir en ambientes áridos, caracterizados por bajos niveles de humedad, suelos salinos y temperat...
Intestinal bacteria are an important indicator of the health of their host. Incorporating periodic assessment of the taxonomic composition of these microorganisms into management and conservation plans can be a valuable tool to detect changes that may jeopardize the survival of threatened populations. Here we describe the diversity and abundance of...
The book “Reptiles and amphibians” is a compilation of current trends in herpetology, focusing on evolution, physiology, monitoring, bioacoustics, threats and conservation biology. All the chapters present an interesting aspect of the biology of reptiles and amphibians, encompassing different groups of these animals like frogs, toads, newts, chelon...
This study conducted a bioassay on frog tadpoles of the Mexican endemic species Dryophytes plicatus exposed to lead and iron. This species was used because some of its populations live near urban areas that may exposed them to pollutants, such as heavy metals due to industrial processes or mining industry. Specimens in a post-embryonic stage of Dry...
This is a review paper that addresses the issue of macroscopic anomalies in anuran amphibian larvae. Currently, the cause of many anomalies in amphibians is known totally or partially, such as those caused by genetic factors (mutations, albinism and cauda bifida), by infectious agents (viruses, bacteria, fungi, protozoa and helminth parasites), by...
In this work was conducted a bio-monitoring and a bioassay in a population exposed to lead and iron of the frog Hyla plicata from Hidalgo, Mexico, to identify possible anomalies caused by contact with these elements. This species was used, as it is in the category "threatened" by the NOM-059-SEMARNAT-2001, and some of their populations living near...

Visual, spectrochemical, and histochemical analyses of tadpoles of two tailless amphibian species (Rana temporaria L. and Bufo bufo L) developed under simulation of water pollution by plumbum and ferruginous alloys demonstrated an alimentary way of the delivery of these metal ions in the organism. Accumulation of these metal ions occurs in intestin...
The effect of pond pollution with lead- and iron-containing alloys on the morphogenesis of brown frog (Rana temporaria), moor frog (Rana arvalis), and common toad (Bufo bufo) tadpoles was studied in simulation experiments. Observations showed that metal particles were ingested by tadpoles and produced a significant effect on their body dimensions....
Morphologic, spectrochemical and histochemical examination of R. temporaria and B. bufo tadpoles grown in water where fragments of steel and lead were introduced reveals ingestion as the entry path of iron and lead ions into the animals’ body. Accumulation of lead and iron was detected in tadpoles’ gut and liver, increasing in the course of their d...
We studied influence of anthropogenic pollution of spawning ponds on embryogenesis of the common and the moor frogs (Rana temporaria Linnaeus 1758, and Rana arvalis Nilsson 1852) from the natural population of the urban and the suburban territories of Moscow. Counts of larvae with anomalies in samples, fixed at different stages, indicated that in M...
