Resumen en español

Hicieron la vida posible hace millones de años y siguen siendo indispensables, ya sea que nos enfoquemos en su relación con el oxígeno, el carbono o el nitrógeno, o bien, en su papel en las redes tróficas y en que procesan casi cualquier tipo de materia orgánica en este enorme territorio de transformaciones que es nuestro mundo. Las bacterias y las arqueas son aún materia de estudio, pero lo que ya sabemos es asombroso.

Resumen en español

Las estimaciones de biomasa en huertos familiares se basan principalmente en el componente arbóreo y pocos estudios cuantifican el componente herbáceo perenne. Este componente es importante en los trópicos húmedos de Mesoamérica, donde se cultivan distintas variedades y especies de plátano (Musa spp). Este cultivo representa una biomasa dinámicamente estable dentro de huertos familiares y proporciona a los propietarios una producción continua de alimentos e ingresos en efectivo. El objetivo de este estudio fue producir un modelo alométrico para estimar la biomasa de plantas de plátano utilizando datos dasonómicos, compararlo con otros modelos y estimar la biomasa de plantas de plátano cultivadas en los huertos familiares en el estado de Tabasco, México. Esto se basó en la hipótesis de que 1) la formulación de modelos específicos da como resultado estimaciones más precisas de la biomasa en pie de las plantas de banana; y 2) las plantas de banana contribuyen a una proporción significativa de la biomasa total en los huertos. Fueron recolectados los datos dasonómicos y el peso seco de los componentes por encima y por debajo del suelo de 30 plantas individuales de la especie más abundante de plátano (Musa balbisiana Colla) en los huertos familiares de la región de Los Ríos en Tabasco, México. La biomasa promedio del total de plantas cosechadas en los huertos familiares fue de 5.85 kg planta-¹, con un rango de 0.52 – 13.32 kg planta-¹. La biomasa sobre el suelo y el cormo representan el 87.6% y el 12.4% de la biomasa total respectivamente. La biomasa aérea estaba fuertemente correlacionada con el diámetro del tallo (DBH), y en menor medida con la altura.

Los modelos de Husch y Schumacher – Hall con las variables diámetro a 30 cm (d30), altura de tallo (HF) y altura total (HT) tuvieron los mejores rendimientos estadísticos, sin embargo, con base en la validación cruzada el mejor modelo fue el propuesto por Kopezky, con la ecuación AGB = -0.0927 + 0.0203 * DBH2, donde AGB es la biomasa aérea y el DBH es el diámetro a la altura del pecho. En los huertos con plátano, la biomasa de plátano era entre 0.1 y 1 t ha-¹, y en algunos casos entre 2 y 5 t ha-1. La densidad media de la biomasa total de las plantas de plátano, en una muestra de 69 huertos familiares donde había plátanos, fue de 688 kg ha-¹, correspondiente al 2% de la biomasa aérea en los huertos familiares de la región de estudio.

Resumen en inglés

Estimates of biomass in homegardens are primarily based on the tree component and few studies quantify the perennial herbaceous component. This component is of importance in the humid tropics of Mesoamerica, where distinct varieties and species of banana (Musa spp) are cultivated. This crop represents a dynamically stable biomass within homegardens and provides owners with continual production for alimentation and cash income. The aim of this study was to produce an allometric model for estimating the biomass of banana plants using dasonomic data, compare it to other models and estimate the biomass of cultivated banana plants from homegardens in the state of Tabasco, Mexico. This was based on the hypothesis that 1) the formulation of specific allometric models results in more precise estimations of the standing biomass of banana plants; and 2) banana plants contribute a significant proportion of the total biomass in homegardens. Dasonomic data and the dry weight of the above and below ground components of 30 individual plants of the most abundant species of banana (Musa balbisiana Colla) were collected in homegardens of the Los Rios region in Tabasco, Mexico. The mean biomass of the total plants of M. balbisiana harvested from homegardens was 5.85 kg plant-¹, with a range of 0.52 – 13.32 kg plant-¹. The above-ground and corm biomass represent 87.6% and 12.4% of total biomass respectively. The above-ground biomass (AGB) was strongly correlated with pseudostem diameter (DBH) and to a lesser degree with height data.

The Husch and Schumacher – Hall models, with the variables pseudostem diameter at a height of 30cm (d30), height of the pseudostem (HF) and total height (HT), performed best statistically; however, based on the crossed validation, the best model was that proposed by Kopezky, with the equation AGB= -0.0927+0.0203*DBH2. In homegardens with banana plants, the banana biomass was between 0.1 and 1 t ha-¹, and in some cases between 2 and 5 t ha-¹. The mean density of the total biomass of the banana plants, in a sample of 69 homegardens where bananas were present, was 688 kg ha-1, corresponding to 2% of above-ground biomass in the homegardens of the region of study.

Resumen en inglés

Background: The south of Mexico is the least developed part of the country but its basins generate more than 60% of the country’s available water. Though disturbances to the rivers caused by development are still low, there is concern about the environmental health of the rivers. The calculation of the sediment load with a focus in fine fraction, where nutrients are found, is a priority. However, models for suspended sediment transport in large rivers are difficult to formulate because they carry a large amount of cohesive sediments, those cohesive sediments form aggregates or flocs with primary particles that are less than 65 μm. The hydrodynamic behavior of flocs depends on their size, density and shape, which differs from that of non‑cohesive sediments as theirs depends on their interaction with the water column. A classical model to calculate suspended sediment concentration profiles for steady flow conditions is the Rouse equation, which has been extensively validated for non‑cohesive suspended sediment. Some authors have demonstrated that when applied in some large rivers in conjunction with non‑cohesive settling velocity models it does not perform very well. The difficulty comes from the fact that most of the suspended sediment charge in large rivers is constituted by cohesive sediments.

Results: Suspended sediments from Mexico’s two largest rivers Usumacinta and Grijalva, with a mean flow rate near river mouth of 2020 m³/s and 1150 m³/s respectively, were analyzed in a rotating annular flume (RAF). The shear velocity obtained in the field by ADCP was reproduced in the annular flume, the size and shape of flocs were obtained by means of PTV. Settling velocity was also obtained to calibrate a settling velocity model appropriate for cohesive sediments. Conclusions: The settling velocity model developed for cohesive sediments in conjunction with the Rouse equation allowed the reproduction of suspended sediment concentration profiles for the rivers Usumacinta and Grijalva. The estimated concentration profiles were compared and validated with the measured concentration profiles in the field. Thus, the model obtained through this research can be used to estimate nutrient delivery to the sea from the largest rivers in Mexico.

Resumen en inglés

Assessments of trophic diversity are critical for evaluating ecological integrity of habitats, but interpretations of such assessments require an understanding of variation across natural environmental gradients. This can be problematic when comparing structure of assemblages in under-studied regions or habitats, such as watersheds in dry tropical forests. Here,we compared assemblage-wide trophic metrics and intraspecific variation for a subset of consumer traits across rivers and among different ecosystem types within the Grijalva and Usumacinta River basins of Mexico. The two rivers differ with respect to flow-regime alteration and climate: the Grijalva River has been hydrologically altered by a series of dams and has wet and dry tropical forests in its watershed, whereas the Usumacinta River remains unimpounded with a watershed dominated by tropical wet forest. Use of allochthonous resourceswas pervasive in Usumacinta basin tributaries,with stable isotope signatures suggesting that many fishes directly consumed riparian plants and detritus. In contrast, fish assemblages inGrijalva basin tributaries were supported by higher proportions of in-stream production. Food-chain length was highest in a Grijalva River reservoir fish assemblage, although trophic diversity was lowin the impounded systemcompared to the mainstem Usumacinta River, where fishes consumed the broadest variety of food resources. We also observed differences in trophic ecology and body nutrient content within taxa across habitat types and basins. The differences we observed suggest that even in relatively intact watersheds, expectations for trophic structure in tropical streams should be adjusted based on factors such as discharge, climate, and riparian forest cover.

Resumen en español

La zona ribereña es la franja de vegetación que se encuentra en las márgenes de los ríos y arroyos, formando corredores biológicos e influyendo en el funcionamiento ecológico de estos ecosistemas. A pesar de su importancia, el paisaje ribereño está siendo altamente degradado por actividades humanas, lo cual afecta la estructura y composición de la comunidad de macroinvertebrados. El objetivo del presente trabajo fue evaluar el impacto de los cambios de uso de suelo en arroyos con ambiente de bosque y pastizal en la subcuenca del río Pichucalco, Chiapas sobre la estructura y funcionamiento de la comunidad de macroinvertebrados. Se eligieron tres arroyos con ambiente de bosque y tres con ambiente de pastizal, se evaluó el hábitat físico, calidad del agua, fuentes de materia orgánica (hojarasca y algas) y macroinvertebrados. El muestreo se realizó mensualmente durante la temporada de secas (febrero a mayo de 2017). La menor cobertura vegetal en los arroyos de pastizal influyó en las altas temperaturas del agua, conductividad, sólidos suspendidos totales, concentración de fósforo total, clorofila a, concentración de oxígeno disuelto y menor hojarasca en esos ambientes.

La diversidad, riqueza e índices bióticos proporción de Ephemeroptera, Plecoptera y Trichoptera, no mostraron diferencias entre los sitios, aunque la abundancia fue mayor en los arroyos de Pastizal. La estructura comunitaria de macroinvertebrados presentó diferencias significativas entre ambientes, principalmente por las densidades de Chironomidae y algunos Ephemeroptera. Los grupos recolector y raspador dictaron las diferencias entre los sitios. Los resultados sugieren que es conveniente conservar los remanentes de vegetación ribereña en los arroyos de bosque, y en los arroyos de pastizal se propone reforestar las zonas ribereñas con vegetación arbórea nativa. Estas acciones podrían mejorar el funcionamiento y los servicios ecosistémicos que ofrecen: retención de nutrientes y mantenimiento de la biodiversidad.

Resumen en inglés

Salinization and land use changes (LUC) threat the ecological functioning of coastal wetlands, which are particularly vulnerable to climate change. The objective of this study was to develop a rapid identification and assessment protocol of threatened wetlands that have the potential for conservation and restoration. The selection of wetlands was based on a socioecological classification, including water physicochemical variables, land use estimation, land tenure, and management practices. The selected wetlands were then classified into three categories: (a) freshwater wetlands exposed to saline intrusion, (b) wetlands in agricultural areas, and (c) wetland as biological corridors. From the 18 wetlands visited, 11 were classified as wetlands in agricultural areas that can also act as corridors, and the remaining seven were wetlands exposed to salinization. Our proposal is a practical instrument for identifying potential wetland restoration sites in an area where biological, hydrological, and water quality data was limited.

Resumen en inglés

We studied whether agrobiodiversity in home gardens reflects the cultural landscapes that embed them. We compared floristic composition, biomass and cover of trees in home gardens between the cultural landscapes on mountain slopes (MSL), small hills (SHL), and floodplains (FPL) in a segment of the Grijalva–Usumacinta watershed in the tropical lowlands of Tabasco, Mexico. We characterized the cultural landscapes based on information obtained through questionnaires, identified species andmeasured tree height and diameter at breast height in random samples of home gardens from two localities in each case. The cultural landscapes showed distinct land use combinations: MSL comprised subsistence agriculture, pasturelands and forests; SHL pasturelands, some secondary vegetation and industrial agriculture fields; and FPL mainly industrial agriculture fields and pasturelands. Total species richness was greater in MSL than in SHL and FPL. Mean species richness was greater in MSL and SHL (22.4 and 15.8 respectively) than in FPL(7.2), aswas themean number of individuals per home garden (98.2, 94.1 and 20.4. Dominant species in home gardens in FPL and SHL included particular secondary species for each landscape,whereas single or double occurrences of mature forest species were distinctive of home gardens in MSL. Mean biomass was greater inMSLthan in SHLand FPL(37.1, 28.2 and 23.7 Mg C ha-1), as was tree cover (1.06, 0.95 and 0.76 m2/m2). We conclude that agrobiodiversity varies considerably among cultural landscapes and recommend the design of specific policies to enhance its conservation in each of them.

Resumen en español

Antecedentes: La vegetación riparia está influenciada fuertemente por los usos de suelo adyacentes. Aunque se sabe que los procesos de urbanización pueden afectar la composición de las especies leñosas y la condición ecológica de la zona riparia, es necesario el entendimiento de las respuestas específicas a estos procesos. Hipótesis: La calidad de las zonas riparias está inversamente relacionada con el grado de urbanización de zonas adyacentes, y los usos del suelo que propicien una cobertura forestal aseguran una condición menos degradada y una diversidad mayor de especies. Sitio de estudio y año del estudio: Cuenca del Río Sabinal, Chiapas, México, 2015. Métodos: Se compararon medidas del Índice de Calidad Riparia (ICR) y la composición de especies leñosas en tres condiciones de uso del suelo (bosque secundario, pastizales y cultivos y asentamientos humanos). Resultados: Las zonas riparias adyacentes a los bosques secundarios mostraron un ICR mayor que las cercanas a pastizales y cultivos y asentamientos humanos. Las zonas riparias en los bosques secundarios también tuvieron una condición de vegetación y suelo mejores, mientras que las riberas adyacentes a asentamientos humanos se observaron pavimentadas y erosionadas, presentando compactación del suelo. La riqueza y diversidad de especies se correlacionaron positivamente con el ICR y fueron mayores en las zonas riparias adyacentes a los bosques secundarios que en zonas con asentamientos humanos. Conclusiones: Aunque el pastoreo y el cultivo afectan la zona riparia, la expansión de las áreas urbanas tiene mayor impacto al reducir la riqueza y diversidad de especies leñosas, alterando la composición de especies, favoreciendo la compactación del suelo y erosión de los márgenes del río, resultando en una calidad riparia menor.

Resumen en inglés

Background: Riparian vegetation is strongly influenced by the surrounding land use. While it is known that urbanization processes can affect plant species composition and the ecological condition of the riparian zone, the specific responses require a fuller understanding. Hypothesis: The quality of riparian zones is inversely related to the degree of urbanization of adjacent areas, and that land uses that provide forest cover ensure a less degraded condition and greater diversity of species. Study site and year of study: Sabinal River basin, Chiapas, Mexico, 2015. Methods: Measures of the Riparian Quality Index (RQI) and plant species composition were compared among three different land use conditions (secondary forest, grasslands and crops, and human settlements). Results: Riparian zones adjacent to secondary forest showed higher RQI than those next to grasslands and crops and human settlements. Riparian zones within secondary forest also had a higher woody species richness and better substrate condition, whereas reaches adjacent to human settlements appeared paved and eroded, exhibiting soil compaction. Species richness and diversity were positively correlated to the RQI and were greater in riparian zones adjacent to secondary forest than in those next to human settlements. Conclusions: While grazing and cultivation affect the riparian zone, expansion of urban areas has a greater impact by reducing woody species richness and diversity, altering species composition and favoring soil compaction and bank erosion, which results in reduced riparian quality.
