Aunque es un tema relevante por sus implicaciones, no existen estudios que hayan sistematizado el conocimiento generado con respecto a las especies involucradas y las características del conflicto. Esta investigación, a través de una revisión sistemática de bases de datos y un análisis narrativo de contenido, identifica y analiza el conflicto humano-cocodrilo a nivel mundial en 28 artículos, con base en el origen y tendencia de las investigaciones, especies involucradas y tipo de interacción. La relación conflictiva es explicada a través de aspecto biológicos como la reproducción o dieta del saurio, así como de su crecimiento poblacional o demográfico, pero también de factores ambientales como el nivel de agua o temperatura, se identificaron las repercusiones económicas y para la conservación de las especies asociadas a este conflicto.

This work aims to describe dispersal of seeds of the columnar cactus Stenocereus queretaroensis by its main fruit consumers (bats and birds), using the criteria of legitimacy and efficiency. A disperser is legitimate when seeds pass through the gut without losing germination capability, and is efficient if the seeds are transported to places where they have the potential for germination and establishment as seedlings. We conducted direct observations in order to identify the main consumer species of S. queretaroensis fruits. Seed germination was evaluated by comparing those that pass through the gut of two bat species, Artibeus lituratus and Leptonycteris yerbabuenae, and two bird species, Icterus pustulatus and Melanerpes chrysogenys, using the parameters germination percentage and germination rate. To evaluate seed deposition patterns by bats and birds within the study area, 20 seed traps were set: 10 below the canopies of local trees, and 10 in open spaces. Nine species of bats and 13 species of birds were found to consume S. queretaroensis fruits. The four tested species can be considered legitimate dispersers, but germination percentage differed among these disperser species. Seeds defecated by birds show the highest speed of germination and lowest average time to germinate, compared with control seeds. In terms of deposition patterns, however, the bats dropped the highest number of seeds, and deposited them both under the canopy and in open areas, whereas birds drop a lower amount and under the canopy only.

Fewer studies have analyzed the effect of a predator's presence or abundance, and those studies have usually been conducted under controlled conditions or using scats, urines, or odors. We tested if apprehension in collared peccaries (Dicotyles angulatus) was affected not just by habitat structure but also by level of resource availability, and presence of top predators (puma [Puma concolor] and jaguar [Panthera onca]) in the immediate area. We classified microhabitats with different levels of risk based on vegetation structure, and compared apprehension of peccaries in shrubland, edge, and forest with sparse understory. To evaluate perceived predation risk, we used giving up densities (GUDs) in 3 trials with different food quantity. We related daily GUDs to predator presence, according to pictures recorded on trail cameras located around the experimental sites. The shrubland microhabitat was classified as the most dangerous, where peccaries were most fearful, while the edge and the forest interior were considered safer. Visibility was the habitat structure variable that most explained the levels of apprehension. Results from trials on days with the greatest numbers of predator photos were more similar among microhabitats, and peccaries left higher GUDs on the days when predators were photographed in the area. Food availability had a minor influence on GUDs. Sites and microhabitats that favor ambush cover are more risky for prey. Predator presence in the area modified temporally the perception of predation risk in prey, which expressed more apprehension and foraged less in the area at those times.

For this task, many studies have used both parametric and non-parametric approximations with a variety of results. This urges the necessity of developing more call libraries, that should be analysed using the different statistical approaches to test their performance. This could be relevant in countries holding high biodiversity where the knowledge of the variation in the call structure among species is still scarce. We constructed and validated a call library from bats inhabiting a mountain ecosystem of central Mexico using the Linear Discriminant Function, Artificial Neural Network and Random Forest approaches. We recorded and analysed 2,325 pulses from 114 individuals and 16 bat species of the families Vespertilionidae, Mormoopidae, Molossidae, and Natalidae. The Random forest model (81.3%) was the better species predictor over the artificial neural network and the discriminant function analysis (69% and 62.1%, respectively). Our work is one of the few attempts to do this exercise that has been conducted in Mexico. The library can be useful as a starting point of research in other regions of the highlands in central Mexico where the information is still scarce.

of evaluating BC with the Fulton index and interpreting the results with quartiles is predominant. However, the wide variety of indices
available provides a diversity of tools with which BC can be interpreted in multiple ways. In this study, three indices based on the function
of length and weight were evaluated: the Fulton index (K), relative condition index (Kn), and scaled mass index (SMI). The body condition
score (BCS) index was also adapted. This was performed as a clinical evaluation of specific morpho-anatomical points. The Fulton index
presented a strong relationship with corporal size that generates poor interpretation, scoring low BC in small individuals and high BC in
large individuals. This problem does not occur in Kn, SMI nor BCS. SMI and Kn are difficult to interpret, but this is normally conducted by
quartiles, generating ambiguous and potentially misleading explanations. The use of BCS avoids these complications because its direct and
simple evaluation acts to convert the abstract numbers of the indices to a clinical reality.

Es posible que, aún en la actualidad, al ocelote no le guste el fuego. El fuego no sólo cambiaría su apariencia de por vida, como cuenta la leyenda, sino que, incluso en la vida real, podría cambiar su forma de vivir, si el fuego provocara un incendio forestal ¿Qué pasa si el fuego afecta el lugar donde vive, su hábitat? Mientras ocurre el incendio, el ocelote, para sobrevivir, deberá huir de ahí para evitar quemarse, pero cuando el fuego haya cesado, tiempo después ¿podría el ocelote regresar a donde solía vivir? Eso dependerá de la extensión y severidad del incendio, de cuánto se transformó el hábitat.

The physical and chemical characteristics of these compounds, as well as their versatility in agricultural, domestic, and public health use, have led them to become widely present in the environment. The objectives of this study were to evaluate the spatiotemporal distribution of pesticides in the surface water of the Ayuquila-Armería river and to conduct an ecotoxicological risk assessment in algae, macroinvertebrates, and fish. The presence of 11 analytes was determined, being λ-cyhalothrin, ametrine, and malathion the pesticides with highest concentrations, and carbendazim, malathion, and glyphosate those with the highest frequency of detection (> 70 %). The number of pesticides detected per sample presented no significant temporal differences, and there was no significant effect of the crops or vegetat...

This study was aimed to evaluate the role of carnivores in endozoochory and diploendozoochory, as well as their effect on seed viability, scarification, and germination in two forest ecosystems: temperate and tropical dry forest. We collected carnivore scat in the Protected Natural Area of Sierra Fría in Aguascalientes, Mexico, for 2 years to determine the abundance and richness of seeds dispersed by each carnivore species, through scat analysis. We assessed seed viability through optical densitometry using X‐rays, analyzed seed scarification by measuring seed coat thickness using a scanning electron microscope, and evaluated seed germination in an experiment as the percentage of seeds germinated per carnivore disperser, plant species, and forest type. In the temperate forest, four plant species (but mainly Arctostaphylos pungens) were dispersed by four mammal species. The gray fox dispersed the highest average number of seeds per scat (66.8 seeds). Bobcat dispersed seeds through diploendozoochory, which was inferred from rabbit (Sylvilagus floridanus) hair detected in their scats. The tropical dry forest presented higher abundance of seeds and richness of dispersed plant species (four species) than in the temperate forest, and the coati dispersed the highest number of seeds (8,639 seeds). Endozoochory and diploendozoochory did not affect viability in thick‐testa seeds (1,480 µm) in temperate forest and thin‐testa seeds (281 µm) in tropical dry forest. Endozoochory improved the selective germination of seeds. Nine plant species were dispersed by endozoochory, but only one species (Juniperus sp.) by diploendozoochory. These results suggest that carnivores can perform an important ecological function by dispersing a great abundance of seeds, scarifying these seeds causing the formation of holes and cracks in the testas without affecting viability, and promoting the selective germination of seeds.

Endozoochory and diploendozoochory did not affect viability in thick‐testa seeds (1,480 µm) in temperate forest and thin‐testa seeds (281 µm) in tropical dry forest. Endozoochory improved the selective germination of seeds. Nine plant species were dispersed by endozoochory, but only one species (Juniperus sp.) by diploendozoochory. These results suggest that carnivores can perform an important ecological function by dispersing a great abundance of seeds, scarifying these seeds causing the formation of holes and cracks in the testas without affecting viability, and promoting the selective germination of seeds.

To identify the presence of bats in each roost, we used two approaches: internal inspections, including the specific search of bats and their signs (feces, noise, dead bodies), and external inspections, using the observation and capture of bats outside the cave (Altringham 1996; Kunz and Parsons 2009). To capture bats, we used several techniques such as manual nets, mist nests and harp traps, according to the cave conditions, difficulty of capture and the number of bats in the roost (Kunz 1982). Also, when it was not possible to capture individuals, ultrasonic recordings were conducted using a Pettersson 240x bat detector, in particular to register the presence of insectivorous bats,
