Resumen en inglés

The West Indian fruit fly, Anastrepha obliqua (Macquart), is the second most important tephritid fruit fly in Mexico, infesting mango, hog plum and guava fruits. To control this pest, the Mexican government has implemented the use of the sterile insect technique (SIT), which involves the mass production, sterilization and release of flies. However, the A. obliqua laboratory males used in SIT are selected to a lesser extent by the wild females during competitiveness tests. The objective of this study was to compare the effects of males fed on fruit fly food enriched with Providencia rettgeri to those in males fed on food alone, assessing male mating competitiveness, capture of females using traps baited with males fed with the enriched diet and sex pheromone components. The results indicated that males fed with the diet enriched with P. rettgeri had increased mating competitiveness and captured more females in the field cage tests. However, no difference was observed in the proportion of volatile sex pheromone components identified during the calling of A. obliqua males. The results suggest the value of incorporating bacteria into the mass rearing technique of A. obliqua adults in order to improve the sexual competitiveness of males from the laboratory compared to wild males.

Resumen en español

El tapir de Baird (Tapirella bairdii) es una especie amenazada en toda su área de distribución, sin embargo, muchos aspectos de su biología y ecología han sido poco estudiados, debido a su comportamiento evasivo y a sus bajas densidades poblacionales. El objetivo de este estudio fue evaluar los patrones de actividad de T. bairdii en relación con las fases lunares en dos sitios con diferente grado de perturbación humana: la Reserva de la Biosfera de Calakmul (RBC) y el Ejido Nuevo Becal (NB). Se monitorearon 20 cuerpos de agua durante18 meses mediante el método de foto-trampeo. Se determinó la tasa de captura (TC) y se registraron las fases lunares correspondientes para ambos sitios. La TC de T. bairdii tapir fue de 0.054 en NB y de 0.029 en la RBC. T. bairdii fue más activo en el periodo nocturno-crepuscular. En general, T.bairdii. mostro una actividad importante durante las fases de oscuridad, pero estas diferencias no fueron significativas estadísticamente. Sin embargo, se encontró una tendencia de los tapires a moverse activamente en las noches y en las horas más obscuras en NB que en RBC. La preferencia aparente por las noches más obscuras en NB podría ser evidencia de la respuesta por parte de los tapires a la perturbación causada por actividades humanas en ese sitio, mostrando un cambio en su comportamiento evitando salir en periodos de abundante luz en sitios perturbados. Sin embargo, se requiere de mayor investigación para corroborar esta posibilidad.

Resumen en inglés

The Baird’s tapir (Tapirella bairdii) is an endangered species throughout its distribution area, however many aspects of its biology and ecology have been poorly studied, due to its evasive behavior and low densities. The goal of this study was to evaluate the activity patterns of T. bairdii, a large ungulate species from the Neotropics, in relation to moon phases in two sites with different degree of human perturbation: the Calakmul Biosphere Reserve (CBR) and the Nuevo Becal (NB) community. We monitored twenty waterbodies in each site for 18 months using camera traps. The photographic capture rate (CR) and the corresponding moon phases for both sites were recorded. The CR of T. bairdii was 0.054 in NB and 0.029 in CBR. T. bairdii was more active at night and dawn-twilight periods. In general, T. bairdii showed major activity during the dark moon phases but the differences with the light phases were not statistically significant. However, we found a trend of tapirs to be more active in dark nights and in the darkest hours in NB than CBR. The apparent preferences for dark nights in NB could be caused by the perturbation caused by human activities at site, which may have influenced the behavior of the tapir that avoid moving out in periods of abundant light in disturbed sites. More research is needed to confirm this finding.

Resumen en inglés

In the Yucatan Peninsula, the ponerine ant Neoponera villosa nests almost exclusively in tank bromeliads, Aechmea bracteata. In this study, we aimed to determine the factors influencing nest site selection during nest relocation which is regularly promoted by hurricanes in this area. Using ants with and without previous experience of Ae. bracteata, we tested their preference for refuges consisting of Ae. bracteata leaves over two other bromeliads, Ae. bromeliifolia and Ananas comosus. We further evaluated bromeliad-associated traits that could influence nest site selection (form and size). Workers with and without previous contact with Ae. bracteata significantly preferred this species over others, suggesting the existence of an innate attraction to this bromeliad. However, preference was not influenced by previous contact with Ae. bracteata. Workers easily discriminated between shelters of Ae. bracteata and A. comosus, but not those of the closely related Ae. bromeliifolia. In marked contrast, ants discriminated between similar sized Ae. bracteata and Ae. bromeliifolia plants, suggesting that chemical cues and plant structure play an important role. Size was also significant as they selected the largest plant when provided two dissimilar Ae. bracteata plants. Nest site selection by N. villosa workers seems to depend on innate preferences but familiarization with plant stimuli is not excluded.

Resumen en español

Se estudió el comportamiento depredador de dos especies de arañas del género Phonotimpus (Araneae: Phrurolithidae) frente a cuatro tipos diferentes de presas potenciales (un Collembola, dos Hemiptera y un Psocoptera). Estas arañas habitan en la hojarasca del suelo de un bosque de niebla y de un cafetal en Chiapas, México. No existen estudios previos sobre el comportamiento de caza de esta familia de arañas. Debido al reducido tamaño de las arañas, el estudio se realizó en laboratorio, mediante videograbaciones de los encuentros con cada tipo de presa. A partir de las grabaciones se elaboró un catálogo de 16 actos de comportamiento que las arañas presentaron durante los encuentros con las presas, entre los que destacan el de “abanicar” y el de “ataque”. Las grabaciones evidenciaron que ambas especies de arañas tuvieron una capacidad significativamente mayor de ataque y captura de los colémbolos que de los hemípteros y psocópteros, además de presentar un repertorio más variado de actos frente a los colémbolos y, para Phonotimpus pennimani un mayor nivel de actividad durante los encuentros con colémbolos. Así, nuestros resultados son similares a los de otros autores que estudiaron el consumo de presas en laboratorio, por dos especies distintas de Phrurolithidae, indicando que es altamente posible que en su hábitat natural los colémbolos sean parte importante de las presas de las Phrurolithidae. Las grabaciones también mostraron que ambas especies de arañas emplean dos estrategias de caza. Una es la emboscada, donde la araña permanece fija en un sitio por periodos relativamente prolongados, a la espera de la aproximación de una presa potencial, y la otra es la búsqueda activa, en la que la araña recorre activamente su entorno hasta que se topa con una presa potencial. De las dos estrategias, hubo un claro predominio de la emboscada, en cuanto su distribución de tiempos durante los encuentros.

Resumen en inglés

We studied the predatory behavior of two spider species of the genus Phonotimpus (Araneae: Phrurolithidae) when confronted with four different types of potential prey (one Collembola, two Hemiptera and one Psocoptera). These spiders live in the soil leaf litter of a cloud forest and coffee orchards in Chiapas, Mexico. There are no previous studies of the hunting behavior for this spiders’ family. Due to the small size of the spiders, the study was made in laboratory conditions with video recordings of the encounters with each prey type. From the analyses of the video recordings we established a catalog of 16 behavioral acts that the spiders displayed in the encounters with prey, among these we characterized “waving” and “attack”. The recordings showed that both spider species had significant higher aptitudes to attack and capture springtails than hemipterans and psocopterans, the spiders displayed a richer behavioral repertoire when confronted the springtails and, for Phonotimpus pennimani a higher activity level when confronting the springtails. Thus, our results are similar to other studies on prey consumption in laboratory conditions by two different species of Phrurolithidae, pointing as highly possible that, in its natural habitat, springtails are an important part of the prey spectrum of the Phrurolithidae. The recordings also showed that both spider species employ two hunting strategies. One is ambushing, where the spider remains fixed in one place for relatively long periods, waiting for the approach of a potential prey, and the other is active searching, where the spider actively wanders its milieu until it encounters a potential prey. In terms of the distribution of times during encounters, ambushing predominated over active searching.

Resumen en inglés

Some social species exhibit high levels of fission–fusion dynamics (FFD) that improve foraging efficiency. In this study, we shed light on the way that FFD allows animal groups to cope with fluctuations in fruit availability. We explore the relative contribution of fruit availability and social factors like sex in determining association and proximity patterns in spider monkeys. We tested the influence of fruit availability and social factors on the association and proximity patterns using three‐year data from a group of spider monkeys in the Yucatan Peninsula of Mexico. We identified subgroup members and estimated their Interindividual distances through instantaneous scan sampling. We evaluated fruit availability by monitoring the phenology ofthe 10 most important food tree species for spider monkeys in the study site. Social network analyses allowed us to evaluate association and proximity patterns in subgroups. We showed that association patterns vary between seasons, respond to changes in fruit availability, and are influenced by the sex of individuals, likely reflecting biological and behavioral differences between sexes and the interplay between ecological and social factors. In contrast, proximity patterns were minimally affected by changes in fruit availability, suggesting that social factors are more important than food availability in determining cohesion within subgroups.

Resumen en inglés

In the current study, we examine how the activities of earthworms (Lumbricus terrestris) affect microplastic (MP) distribution and concentration in soil, with a focus on low density polyethylene (LDPE). We also want to determine if MPs can be flushed out with water. We used a laboratory sandy soil column (polyvinyl chloride tube) experimental set-up and tested five different treatments: (1) treatment with just soil (control) to check if the saturated conductivity (Ksat) could be impacted by MP, (2) treatment with MP, (3) treatment with MP and litter, (4) treatment with earthworms and litter as a second control for treatment 5 and (5) treatment with MPs, earthworms and litter. Each treatment consisted of eight replicates. For the treatments with MP, the concentration of MP added at the start of the experiment was 7 % by weight (3.97 g, polyethylene, 50 % 1 mm–250 µm, 30 % 250 µm–150 µm and 20 % <150 µm) based on 52.78 g of dry litter from Populus nigra. In the treatments using earthworms, two adult earthworms, with an initial average weight of (7.14 ± 0.26) g, were placed in each column. Results showed that LDPE particles could be introduced into the soil by the earthworms.

MP particles were detected in each soil sample and within different soil layers for the earthworm treatments. Earthworms showed a tendency to transport the smaller MP particles and that the amount of MPs in size class <250 μm increased in soil samples with increasing soil depth in comparison to the other size classes. After leaching, MPs were only detected in the leachate from the treatments with the earthworms, and the MP had similar size distributions as the soil samples in the 40–50 cm layer of the treatment with MP, earthworms and litter. The results of this study clearly show that biogenic activities can mobilise MP transport from the surface into the soil and even be leached into drainage. It is highly likely that biogenic activities constitute a potential pathway for MPs to be transported into soil and groundwater.

Resumen en inglés

This book brings a unique perspective to animal movement studies because all cases came from tropical environments where the great diversity, either biological and structurally (trees, shrubs, vines, epiphytes), presents the animal with several options to fulfill its live requirements. These conditions have forced the evolution of unique movement patterns and ecological strategies. Movement is an essential process in the life of all organisms. Animals move because they are hungry, thirsty, to avoid being eaten, or because they want to find mates. Understanding the causes and consequences of animal movement is not an easy task for behavioural ecologists. Many animals are shy, move in secretive ways and are very sensible to human presence, therefore, studying the movements of mammals in tropical environments present logistical and methodological challenges that have recently started to be solved by ecologist around the world. In this book we are compiling a set of extraordinary cases where researchers have used some of the modern technology and the strongest methodological approaches to understand movement patterns in wild tropical mammals. We hope this book will inspire and encourage young researchers to investigate wild mammal´s movements in some of the amazing tropical environments of the world.
