Se presenta un nuevo reporte de Werneria (Asteraceae) para Ecuador, es W. spathulata, una pequeña hierba rizomatosa encontrada en los páramos del volcán Antisana. Además, se documenta el redescubrimiento de Xenophyllum acerosum en el Ecuador después de su primera colección hace 73 años en la provincia de Azuay. Se proveen fotografías del hábito de las dos especies, así como del hábitat donde fueron halladas.

El temazate rojo (Mazama temama) es uno de los cérvidos más abundantes y con más amplia distribución en los bosques neotropicales. Un método para estimar densidades poblacionales es mediante el conteo de heces, para lo cual es necesario conocer la tasa de defecación. Para obtener dicha tasa en este ungulado, se realizaron conteos de los eventos de defecación, durante cuatro días, en tres individuos adultos: dos hembras y un macho; alojados en cautiverio en el parque Xcaret, ubicado en el estado de Quintana Roo, México. La tasa de defecación promedio obtenida fue de 10 ± 3,33 (DE) grupos de excrementos/individuo/día. Este dato permitirá realizar estimaciones de densidad poblacional de esta especie en vida libre.

The present study sought to determine the effect of spatial heterogeneity, a product of the different vegetation mosaics and environmental and structural gradients of the paramo, on the structure of anuran assemblage in a sector of Chingaza National Park. Environmental and structural variables were recorded from aerial photographs taken with a drone in six vegetation mosaics identifying landscape metrics to areas of influence of 50 and 100 m. At the end of 162 hours/person of sampling, we found 45 individuals belonging to four species. The variables mostly related to the structure of anuran assemblages varied with the spatial scale of analysis as follows: (a) at the level of the environmental-structural gradient in the vegetation mosaics (microhabitat scale), the percentage of frailejones, number of trunks of fallen frailejones, air temperature, and wind speed were the most determinant; (b) at the landscape unit level, at an area of influence of 50 m, the effect of the number of classes and in particular, the extent of peatland and peatland vegetation classes was evidenced; and (c) at an area of influence of 100 m scale, the configuration of the landscape units was most important, mainly the extension of the classes of peatland and low scrubs intermixed with pajonal and frailejonal. The results suggest that anurans present a scale-dependent response to spatial heterogeneity, an aspect that should be considered in the protected area's management plans when structuring population monitoring schemes.

Se describe la diversidad, y por primera vez, la distribución vertical de insectos barrenadores (Scolytinae, Platypodinae y Bostrichidae) asociados al borde e interior de un manglar. Para determinar la diversidad en estos espacios, se capturaron insectos con trampas de intercepción cebadas con alcohol etílico al 70 % y mediante una luz ultravioleta como atrayente. Con la finalidad de analizar la distribución vertical, se colocaron trampas cebadas con alcohol etílico a 1,5 m, 6 m y 12 m de altura. De acuerdo con el índice de diversidad (1D) el borde fue 1,36 más diverso que el interior con 15,82 y 11,67 respectivamente. Las trampas utilizadas a 6 m capturaron la mayor diversidad tanto en el borde como en el interior, a pesar de que las trampas a 1,5 m capturaron la mayor abundancia. En el borde, diez de los doce meses presentaron diferencias significativas en su abundancia y para el interior estas diferencias se presentaron en ocho de los doce meses. En cuanto a la diversidad (1D), en el borde estas diferencias estadísticas se presentaron en abril, mayo, julio y agosto, mientras que en el interior en junio, noviembre y diciembre. Tales diferencias pueden estar relacionadas con la variabilidad en las condiciones ambientales del manglar, lo que produce cambios en la estructura y composición de las comunidades de insectos.

La diversidad taxonómica y funcional de los sírfidos los hace fundamentales en los ecosistemas. Además, su sensibilidad a la fragmentación del hábitat por factores antrópicos los hace buenos indicadores ecológicos de la conservación ecosistémica. Establecimos si las comunidades de sírfidos están relacionadas con coberturas vegetales en un gradiente de intervención antrópica en un área boscoso-montañosa de la ciudad de Bogotá. Las coberturas vegetales se identificaron con la metodología de coberturas de uso de la tierra y el sistema Corine Land Cover. Los insectos se recolectaron activamente durante los picos de máxima actividad diaria en un periodo de transición seco-húmedo. Las comunidades de sírfidos y su relación con las coberturas se evaluaron estimando el número efectivo de especies y un análisis de componentes principales (ACP). Se identificaron tres coberturas: Vegetación Secundaria Alta, Tejido Urbano Discontinuo y Bosque Ripario. Los 381 individuos recolectados pertenecen a 24 especies agrupadas en dos subfamilias. Las comunidades de sírfidos en la Vegetación Secundaria Alta y el Bosque Ripario presentaron números efectivos de especies superiores a los hallados en el Tejido Urbano Discontinuo. El ACP sugirió una estrecha asociación entre las especies Lejops mexicanus y Toxomerus watsoni con el Tejido Urbano Discontinuo y la Vegetación Secundaria Alta, mientras Palpada florea, Syrphus shorae, Orphnabaccha golbachi y Allograpta exotica lo son con el Bosque Ripario. La abundancia de sírfidos fue más alta en las coberturas con espacios abiertos y su diversidad fue influenciada por la heterogeneidad y antropización de las coberturas, patrón registrado por primera vez en el Neotrópico.

The present study analyzes the intestinal nematofauna of the orthopteran species Anurogryllus muticus and Neocurtilla claraziana as part of a survey work conducted in pastures from the region of La Plata to isolate entomopathogenic nematode species. Eleven nematode species belonging to the families Thelastomatidae, Travassosinematidae, Cephalobidae, Rhabditidae, and Plectidae are reported. Parasitism percentages from 0.31 to 22.71 % were observed being Blatticola cristovata and Cephalobellus magalhaesi the most prevalent species. Cephalobium nitidum, Cruznema tripartitum, and Plectus parietinus are reported for the first time from Argentina. The findings of the study contribute to a better understanding of the biodiversity status of insect parasitic nematodes of the region.

Agriculture and urban expansion have caused fragmentation of the remaining forests located along the Otún and Consotá river watershed in the municipality of Pereira, Department of Risaralda, Colombia. These forests are dominated by the guadua bamboo species Guadua angustifolia Kunth, which provided raw material for different purposes and additionally fulfills important ecological functions. The aim of this study was to evaluate ecosystems services associated with these forests such as carbon storage, soil water storing capacity, and the financial feasibility related to guadua culms commercialization. The carbon storage was estimated from the aboveground biomass and soil organic matter; soil water storing capacity was associated with physical soil properties. Whereas the provisioning ecosystem service was assessed through a cost-benefit analysis performed with different production scenarios. The carbon stock was found to be 672.3 t C / ha (22 % in biomass and 78 % in the soil at a depth of 45 cm). The average soil water storing capacity was 292.4 m3 / ha. The cost-benefit analysis evidenced the financial feasibility for the scenarios when projected sales are more than 3 % than current. Bamboo forests provide ecosystem services that are yet another justification for better economic compensation and a medium to promote balance between ecosystem services and the financial situation of producers, who derive their incomes from its production.
