“…Algo similar a lo encontrado por Sanabria-Aranda et al (2006). Estudios previos en la especie demuestran una relación entre el tamaño de los utrículos y la eficiencia en la captura de los géneros, es decir un aumento en la riqueza y abundancia de los grupos, con el aumento del tamaño de los utrí-culos (Díaz-Olarte et al, 2007).…”

Capture and selectivity of zooplankton by Utricularia foliosa (Lentibulariaceae) in the Ciénaga de Paredes, Santander, Colombia. Utricularia is a genus of carnivorous plants that capture a wide range of aquatic organisms. Most of these plants grow in environments with nutrients deficiency and have the ability to change the conditions of their microenvironment. The aim of this research was to study the selectivity in the zooplankton capture by Utricularia foliosa in the Ciénaga de Paredes. Our study was undertaken between February and November, 2014. We tried to determine if there is selection in the plant's food resources by the Czekanowski's index, and the selection degree by the Savage and Ivlev's indexes. Additionally, we studied the possible relation between the patterns of zooplankton capture and selection, with physicochemical variables in the swamp. The Czekanowski's index showed a food selection in plant resources throughout the flood pulse, with values between 0.28 and 0.41. We also found a significant positive selection with Savage's index for Lecane sp., Alona sp., Ceriodaphnia sp., and Bosmina sp. (p < 0.05); similar results were obtained with Ivlev's index. The intensity in the selection of each captured genus varied significantly between hydrological periods and between high and low water levels in the swamp. It was possible to identify some changes in the ammonia and nitrate concentration and some variability in the electric conductivity of the swamp, which influenced the captures made by U. foliosa. This is the first paper that allows an approach to understand the selection of food resources for the species, using a selectivity index, and one of the few for the genus. Rev. Biol.

“…Multiple factors control periphyton growth on plants and they can be split into environmental and plant‐related factors. Environmental variables such as light availability, nutrient availability (Siver, ) and grazing pressure by macroinvertebrates strongly influence periphyton density (Bakker, Dobrescu, Straile, & Holmgren, ; Díaz‐Olarte et al., ; Jones et al., ).…”

Periphyton density is similar on native and non‐native plant species

1. Non-native plants increasingly dominate the vegetation in aquatic ecosystemsand thrive in eutrophic conditions. In eutrophic conditions, submerged plants risk being overgrown by epiphytic algae; however, if non-native plants are less susceptible to periphyton than natives, this would contribute to their dominance.Non-native plants may differ from natives in their susceptibility to periphyton growth due to differences in nutrient release, allelopathy and architecture. Yet, there is mixed evidence for whether plants interact with periphyton growth through nutrient release and allelopathy, or whether plants are neutral so that only their architecture matters for periphyton growth.2. We hypothesised that (1) non-native submerged vascular plants support lower periphyton density than native species, (2) native and non-native species are not neutral substrate for periphyton and interact with periphyton and (3) periphyton density increases with the plant structural complexity of plant species.3. We conducted an experiment in a controlled climate chamber where we grew 11 aquatic plant species and an artificial plant analogue in monocultures in buckets. These buckets were inoculated with periphyton that was collected locally from plants and hard substrate. Of the 11 living species, seven are native to Europe and four are non-native. The periphyton density on these plants was quantified after five weeks. 4.We found that the periphyton density did not differ between non-native and native plants and was not related to plant complexity. Three living plant species supported lower periphyton densities than the artificial plant, one supported a higher periphyton density and the other plants supported similar densities. However, there was a strong negative correlation between plant growth and periphyton density. 5.We conclude that the periphyton density varies greatly among plant species, even when these were grown under similar conditions, but there was no indication that the interaction with periphyton differs between native and non-native plant species. Hence, non-native plants do not seem to benefit from reduced periphyton colonisation compared to native species. Instead, certain native and non-native species tolerate eutrophic conditions well and as a consequence, they seem to host less periphyton than less tolerant species.--

“…Durante los tres muestreos realizados la planta se encontraba en estado de floración, contrario a lo que otros autores documentan, donde la planta florece una vez al año entre marzo y mayo (Díaz-Olarte et al 2007, Guisande et al 2004. Las capturas realizadas por los utrículos y su frecuencia de ocurrencia, nos permitió conocer un poco sobre la preferencia alimentaria en la Ciénaga de Paredes, esto podría deberse a la adaptabilidad de U. foliosa, ya que se confirmaron estudios previos que indican que las especies del género Utricularia tienen la capacidad de variar sus hábitos de alimentación de acuerdo con la disponibilidad de organismos presentes en el medio (Guisande et al 2004, Mette et al 2000.…”

“…En Colombia, U. foliosa es la especie acuática más estudiada por su relevancia ecológica a lo largo del caño Yahurcaca en la Amazonia colombiana, encontrándose en lagos y arroyos de baja velocidad de corrientes, pero no en ríos (Díaz-Olarte et al 2007, Guisande et al 2004. Esta planta carnívora se distribuye geográficamente en los departamentos de Arauca, Atlántico, Bolívar, Boyacá, Caquetá, Casanare, César, Chocó, Córdoba, Magdalena, Valle del Cauca, Vaupés, Vichada, otras zonas del Amazonas y para el departamento de Santander existen registros para el río Magdalena en los municipios de Cimitarra y Puerto Wilches (tabla 1).…”
