Resumen en inglés

The biodiversity data typically available for fitting distributional models in the tropics come from museum and scientific collections which are often incomplete and prone to sampling and environmental biases. Nevertheless, most studies undertaken in tropical regions assume that collection data offers a satisfactory environmental coverage without any quantitative assessment. In this study, we investigate the effects of differences in environmental bias and coverage provided by distributional data when aggregated into different grid cell sizes, on the performance of species richness-environment models and predictions. We use an extensive data compilation, including national and regional collections, on the distribution of amphibians, reptiles and fishes in the hydrologic region of the Usumacinta River as a case study. General additive models and environmental variables are used to construct predictive models at 40, 20, 10 and 5 km grid resolutions, based on well-sampled cells. The best multivariate models included nonparametric interaction terms for the effects of precipitation and temperature and suggested an altitudinal shift in the relative importance of energy and water in determining the distribution of species richness.

For fishes, geomorphology accounted for fine scale variation in species richness along the hydrologic network, indicated by peaks in species diversity at the junction of the major rivers where major accumulation of water and sediments occurs. For all taxonomic groups, we found that sampling biases deviated most from the mean bias at the extremes of gradients accounting for important environmental factors. The pattern of environmental bias changed with grid size, with the form and amount of change being casespecific. Biases affected distribution predictions when compared with unbiased datasets. Moreover, not all models resulted best at coarser resolution as it is commonly assumed. Our results demonstrate that bias in the available data must be evaluated before mapping biodiversity distributions, irrespective of the choice of scale.

Resumen en español

El objetivo del estudio fue determinar el valor nutritivo, la fermentación ruminal y la producción de metano in vitro del follaje de especies arbóreas y arbustivas con potencial forrajero como estrategias de alimentación en época de secas y mitigación de las emisiones de metano. El líquido ruminal fue extraído por medio de una sonda esofágica. Se utilizó un diseño en bloques repetidos en el tiempo. El contenido de proteína cruda (PC) y fibra detergente neutro y acida fluctuaron de 6.14% a 21.78%, 44.34% a 77.43% y 16.12% a 49.53% de materia seca (MS). No se encontró diferencia en el volumen máximo de gas (p > 0.05). La degradabilidad fue diferente, observando la mejor en Tithonia diversifolia (760.40 g/kg de MS), Morus alba (800.66 g/kg de MS) y Hibiscus rosa-sinensis (800.16 g/kg de MS), mientras que la más baja fue Megatryrsus maximus (390.40 g/kg de MS y 287.40 g/kg de materia orgánica (MO)) (p < 0.05). No se observó diferencia en la producción de metano (CH4) (p > 0.05). Se concluye que L. leucocephala, P. piscipula, B. alicastrum y G. ulmifolia, T. diversifolia y M. alba tienen un alto potencial para ser incluidos en la dieta de rumiantes como fuentes de proteína en época de secas y estrategias para mitigar las emisiones de metano.

Resumen en inglés

The objective of the study was to determine the nutritional value, ruminal fermentation, and in vitro methane production of foliage of tree and shrubs species with forage potential as feeding strategies in dry season and mitigation of methane emissions. The rumen liquor was taken by an esophageal tube. A repeated block design overtime was used. The content of crude protein (CP) and neutral and acid detergent fiber ranged from 6.14% to 21.78%, 44.34% to 77.43% and 16.12% to 49.53% of dry matter (DM). No difference was found in the maximum volume of gas (p > 0.05). The degradability was different among species, and it was higher for Tithonia diversifolia (760.40 g/kg DM), Morus alba (800.66 g/kg DM) and Hibuscus rosa-sinensis (800.16 g/kg DM), whilst the lower was for Megathyrsus maximus (390.40 g/kg DM and 287.40 g/kg organic matter (OM)) (p < 0.05). No difference in methane (CH4) production was observed (p > 0.05). It is concluded that L. leucocephala, P. piscipula, B. alicastrum and G. ulmifolia, T. diversifolia, and M. alba have a high potential to be included in the ruminant diet as sources of protein in the dry season and strategies to mitigate methane emissions

Resumen en inglés

The present study aims to analyze the role of traditional knowledge in territorial autonomy and environmental governance, as well as the level of interest of different indigenous and non-indigenous actors in the southern Colombian Amazon in applying traditional knowledge to public policy. Using the theoretical approaches of political ecology as well as a qualitative method, we describe a multidisciplinary project developed and implemented to incorporate knowledge systems of indigenous peoples of the Colombian Amazon into environmental policy. The results present an analysis of arguments by indigenous organizations, researchers, and government environmental agency administrators for and against using traditional knowledge to address the global ecological crisis. Through interviews and reports systematized by researchers and local collaborators within the project, we discuss conflicts that emerge when attempts are made to apply traditional knowledge in asymmetrical spaces of power. This includes responses by local residents to the global governance regime, which imposes policies regarding traditional knowledge in indigenous territories, and the possible repercussions of environmental policies on indigenous autonomy regimes in territories considered to be ancestral by indigenous peoples. We conclude that indigenous communities and organizations are more willing to apply traditional knowledge to public policy when the process is oriented toward strengthening their territorial and environmental autonomy than when external actors attempt to use this knowledge to promote global regulatory regimes that are beyond the control of local actors.

Resumen en español

Esta investigación se realizó en la ranchería Guineo 1ª Sección municipio Centro del estado de Tabasco en el año 2018. El objetivo fue probar los hoteles para abejas como una herramienta en una estrategia de educación ambiental basada en la enseñanza situada, con el propósito de crear conocimientos sobre las abejas nativas de la región y cambiar las actitudes de los estudiantes hacia éstas y hacia el medio natural, mediante la generación de experiencias significativas y afinidad emocional hacia las abejas nativas. Dicha estrategia educativa se dirigió a 30 estudiantes de quinto grado de la Primaria Rural Federal Ignacio Zaragoza. Se realizó un diagnóstico inicial de las actitudes y conocimientos de los estudiantes y una evaluación final después de la estrategia educativa. Se trabajó con ellos durante 6 meses, en los cuales adquirieron conocimientos y habilidades cognitivas que se relacionan con su contexto de vida y que tienen diferentes usos dentro de éstas. Se logró un cambio significativo en las actitudes de los estudiantes hacia las abejas nativas y hacia el entorno natural. Se logró la creación de nuevos conocimientos por parte de los estudiantes. No se encontró relación entre los conocimientos y la observación de los hoteles con el cambio de actitudes, pero se encontró una correlación positiva entre el cambio de actitudes hacia las abejas y el cambio de actitudes hacia la naturaleza.

Resumen en inglés

Old-growth tropical forests harbor an immense diversity of tree species but are rapidly being cleared, while secondary forests that regrow on abandoned agricultural lands increase in extent. We assess how tree species richness and composition recover during secondary succession across gradients in environmental conditions and anthropogenic disturbance in an unprecedented multisite analysis for the Neotropics. Secondary forests recover remarkably fast in species richness but slowly in species composition. Secondary forests take a median time of five decades to recover the species richness of old-growth forest (80% recovery after 20 years) based on rarefaction analysis. Full recovery of species composition takes centuries (only 34% recovery after 20 years). A dual strategy that maintains both old-growth forests and species-rich secondary forests is therefore crucial for biodiversity conservation in human-modified tropical landscapes.

Resumen en inglés

Community marine reserves are geographical areas closed to fishing activities, implemented and enforced by the same fishermen that fish around them. Their main objective is to recover commercial stocks of fish and invertebrates. While marine reserves have proven successful in many parts of the world, their success near important marine predator colonies, such as the California sea lion (Zalophus californianus) and the Pacific harbor seal (Phoca vitulina richardii), is yet to be analyzed. In response to the concerns expressed by local fishermen about the impact of the presence of pinnipeds on their communities’ marine reserves, we conducted underwater surveys around four islands in the Pacific west of the Baja California Peninsula: two without reserves (Todos Santos and San Roque); one with a recently established reserve (San Jeronimo); and, a fourth with reserves established eight years ago (Natividad). All these islands are subject to similar rates of exploitation by fishing cooperatives with exclusive rights. We estimated fish biomass and biodiversity in the seas around the islands, applying filters for potential California sea lion and harbor seal prey using known species from the literature. Generalized linear mixed models revealed that the age of the reserve has a significant positive effect on fish biomass, while the site (inside or outside of the reserve) did not, with a similar result found for the biomass of the prey of the California sea lion. Fish biodiversity was also higher around Natividad Island, while invertebrate biodiversity was higher around San Roque.

These findings indicate that marine reserves increase overall fish diversity and biomass, despite the presence of top predators, even increasing the numbers of their potential prey. Community marine reserves may help to improve the resilience of marine mammals to climate-driven phenomena and maintain a healthy marine ecosystem for the benefit of both pinnipeds and fishermen.

Resumen en español

El artículo se propone contrastar de manera sucinta las políticas públicas forestales gestadas en el periodo 1947-1982, a través de los informes de gobierno de los estados de Tabasco y Chiapas (México). Para ello se recopilaron y digitalizaron informes de gobiernos estatales del periodo de estudio, complementados con fuentes secundarias. El método de investigación fue cualitativo con una búsqueda intensiva y extensiva de fuentes, lo cual sirvió para crear una base de datos ordenada por palabras clave. Los resultados son los siguientes: las políticas forestales en ambas entidades fueron divergentes, mientras en Chiapas los gobiernos estatales promovieron intermitentemente el aprovechamiento forestal, en Tabasco, el principal objetivo fue el de hacer producir el campo e incentivar la actividad ganadera, a costa de la deforestación de la selva. No obstante, en ambos, los incendios, la deforestación y las políticas débiles causaron que los recursos forestales continuaran deteriorándose.

Resumen en inglés

The objective of this work is to contrast succinctly the forest public policies that took place in the period 1947-1982 through the government reports of the States of Tabasco and Chiapas (Mexico), through the collection and digitization of State Government reports, supplemented by secondary sources. The method of research was qualitative with an intensive and extensive search of sources, which served to create a database in Microsoft Excel, sorted by keywords. The results are as follows: forest policies in both entities were divergent, while in Chiapas, state governments intermittently promoted forest harvesting, in Tabasco, the main objective was to promote agriculture and cattle raising, at the expense of forest degradation. However, in both cases, fires, deforestation and weak policies caused forest resources to continue to deteriorate.

Resumen en inglés

Chytridiomycosis caused by fungus Batrachochytrium dendrobatidis (Bd) is one of the decline global causes of amphibians. Currently, it is distributed throughout a broad range of climates and ecosystems around the world. An epidemic wave of chytridiomycosis began in North America, resulting in population decline and local extinction of many species, reconfiguring species composition of amphibian communities in the Americas. In Mexico, Bd has caused an amphibian population decrease, and its potential distribution area has not been determined. We reviewed the number of species infected, obtaining Bd frequency of infection by land use and vegetation type, and by elevation range. We examined the known distribution of Bd, estimated the potential distribution, and obtained the bioclimate variables relevant for Bd. Our results indicate that in Mexico, Bd has been detected in 78 species of amphibians in 10 families, from 29 different land use and vegetation types, with cloud forest having the highest number of cases (139) and infected species (15). Bd occurs over an elevation range of 1–3,300 m asl and is most frequent at 1,200–1,500 m asl (36%). In addition to the regions previously described as suitable for Bd, our model included desert, coastal, and tropical forest regions, revealing an increase in the area where amphibians could be at risk of infection. Distribution of Bd is mainly associated with temperature of the wettest quarter and potential evapotranspiration of the warmer quarter. We offer an estimate of the ideal conditions for Bd in Mexico, also information for future studies on Bd and the conservation of amphibians.

Resumen en español

Las enfermedades infecciosas (EIs) emergentes, re-emergentes y las tropicales desatendidas pueden ser localizadas en áreas geográficas específicas, pero fenómenos como el cambio climático, la globalización, las condiciones socioeconómicas y la migración, entre otros, pueden facilitar su rápida transmisión hacia otras regiones. Brotes recientes de Zika, Chikungunya, y Ébola han puesto en alerta la salud pública mundial. Otras enfermedades infecciosas aún persisten y representan severos problemas de salud pública, tales como la tuberculosis, el VIH-sida, la leishmaniasis, el dengue, la malaria y la enfermedad de Chagas, entre otras. Para el diagnóstico, prevención y disminución en la propagación de las EIs, es necesario implementar métodos de diagnóstico precisos, rápidos y accesibles que permitan su atención médica de manera oportuna. Describimos el uso de la nanotecnología, específicamente de “Alocilja Nanopartículas Magnéticas (AMNs)” acopladas a un biosensor, como un nuevo método de diagnóstico de las EIs. Ilustramos su uso potencial para el diagnóstico de la tuberculosis.

Resumen en inglés

Emerging, re-emerging and neglected tropical infectious diseases (IDs) can be restricted to specific geographic zones, but climate change, globalization, social conditions, and migration, among other factors, can trigger their dissemination worldwide. Outbreaks of Zika, Chikungunya and Ebola have threatened public health worldwide. The rapid transmission of these viral diseases exemplifies the potential quick spread of an infectious disease. Yet several infectious diseases that are of major concern for public health, namely tuberculosis, VIH-sida, Leishmaniasis, dengue, malaria, Chagas, among others. To detect and combat the spread of these IDs, we urge, rapid, and accessible diagnostic tests are needed to identify specific pathogens in order to provide early medical care. In this paper, we review the use of nanotechnology, specifically the Alocilja functionalized magnetic nanoparticles (AMNs) coupled to a biosensor, as a new and quick diagnostic test to detect IDs, and exemplify their potential use in the diagnosis of tuberculosis.

Resumen en inglés

Tropical forests are converted at an alarming rate for agricultural use and pastureland, but also regrow naturally through secondary succession. For successful forest restoration, it is essential to understand the mechanisms of secondary succession. These mechanisms may vary across forest types, but analyses across broad spatial scales are lacking. Here, we analyse forest recovery using 1,403 plots that differ in age since agricultural abandonment from 50 sites across the Neotropics. We analyse changes in community composition using species-specific stem wood density (WD), which is a key trait for plant growth, survival and forest carbon storage. In wet forest, succession proceeds from low towards high community WD (acquisitive towards conservative trait values), in line with standard successional theory. However, in dry forest, succession proceeds from high towards low community WD (conservative towards acquisitive trait values), probably because high WD reflects drought tolerance in harsh early successional environments. Dry season intensity drives WD recovery by influencing the start and trajectory of succession, resulting in convergence of the community WD over time as vegetation cover builds up. These ecological insights can be used to improve species selection for reforestation. Reforestation species selected to establish a first protective canopy layer should, among other criteria, ideally have a similar WD to the early successional communities that dominate under the prevailing macroclimatic conditions.
