The composition, abundance and functional diversity of zooplankton from the main channel Middle Paraná River were studied.Monthly samples collected in both ordinary drought periods (1977, 1978, 1981, 2007) extraordinary ones (La Niña events 1971-1972, 1999 -2000).A constant pattern structure was recorded 1971 to 1981 characterised by a strong rotifer dominance.Changes observed last two periods, with planktonic larvae Limnoperna fortunei as new component zooplankton.The showed significant...
Abstract The effect of different concentrations the bivalve Limnoperna fortunei on algal density and structure its filtration rate was estimated in a mesocosm experiment. experiment carried out using containers 200 L three treatments: Control (without bivalves), C1 (with 128 individual C2 256 bivalves). Decrease phytoplankton detected treatments after 6 h. A decrease 52% 86% initial measured C2, respectively, 48 All algae groups showed substantial densities (>60%) composition assemblages...
In the area of Middle Paraná River, Argentina, in pleuston community associated with roots Eichhornia crassipes (Mart.) Solms-Laubach, 1883, an epibiosis non-indigenous mussel Limnoperna fortunei (Dunker, 1857) on native crab Trichodactylus borellianus Nobili, 1896 was occasionally recorded. The organisms were measured, weighed, and photographed. Attached molluscs larger heavier than their host crabs. This new interaction system analyzed regard to several biological ecological...
Limnoperna fortunei is an Asian mussel introduced to South America around 1990. One of the most important impacts this invader probably its grazing on plankton. In study we evaluate vulnerability several planktonic microcrustaceans from Paraná River floodplain predation by adult L. fortunei. We conducted 2-h laboratory feeding experiments where bivalves were offered differing in overall body shape, size, and locomotive abilities. Ingestion clearance rates for each taxon estimated. Results...
AbstractWe recorded, for the first time, byssal hairs in Asian freshwater bivalve Limnoperna fortunei from Paraná River system. We analysed presence of and their distribution on shell relation to habitat size 12 sites. Hairs were present lentic habitats associated with macrophytes or organic matter, but absent lotic environments. The proportion mussels was negatively correlated current velocity. more frequent abundant larger mussels. In general, are a similar length over almost entirely...
Single behavioural interactions between two freshwater planktonic crustaceans and invertebrate predators from different zones of the common environment were studied. The prey organisms cladoceran Ceriodaphnia dubia copepod Notodiaptomus conifer. three shrimp Macrobrachium borellii, crab Trichodactylus borellianus larva dipteran midge Chaoborus. Feeding experiments first performed to document effects exposure time density on predation. All selected fed C. N. conifer, predation rates dependent...
The relationship between the timing of recurrent biological events and seasonal climatic patterns (i.e., phenology) is a crucial ecological process. Changes in phenology are increasingly linked to global climate change. However, current evidence phenological responses recent change subjected substantial regional biases. Most available on climate-driven changes comes from Northern Hemisphere (NH) ecosystems typically involves increases spring summer temperatures, which translate into earlier...
<p>The roots of <em>Eichhornia crassipes</em> provide different microhabitats for invertebrates, including substrate the Asian invasive bivalve <em>Limnoperna fortunei</em>. This work evaluated density and size structure <em>L.</em> <em>fortunei</em> on <em>E. in lentic waterbodies associated with Middle Paraná floodplain. The field was carried out between November 2009–2010, covering phases hydrological regime. Floating meadows...
