Description
  • I have joined the GEA group at UVIC-UCC. I am doing research and coordination activities within the PONDERFUL project (POND Ecosystems for Resilient Future Landscapes in a changing climate) which is a H2020 “Research and Innovation Programme” project funded by the European Union. My research activities are closely related with my expertise: the effect of hydroperiod on the interactions between pond functions, services and biodiversity, and the use of ponds as Nature based solutions.

Article
Fish larvae play an important structuring role for their prey and show ontogenetic shifts in diet. Changes in diet differ between species and habitats and may also be affected by turbidity (eutrophication). We investigated the diet (stomach content) and the food selection (ratio of ingested prey and prey availability) of roach and perch larvae in a...

1. It is well established that terrestrial and aquatic ecosystems are interlinked in a myriad of ways, yet understanding of the role terrestrial particulate organic matter (OM) plays in supporting aquatic macroinvertebrate production is still incomplete and debated. We investigated the role of terrestrial particulate OM (leaf litter) and autochthon...

Interaction between non-native predatory fishes and native galaxiids (Pisces: Galaxiidae) shapes food web structure in Tasmanian lakes, Inland Waters, ABSTRACT Non-native fish invasions threaten native fauna and ecosystem functioning, not least in isolated island lakes. In Tasmania, where the native fish are mostly galaxiids, 9 non-native freshwate...
Article
Full-text available
Nutritional stress, from feeding on low-quality diets or starvation, may cause changes in consumers’ nitrogen isotope ratios (δ¹⁵N = ¹⁵N/¹⁴N) and trophic fractionation (∆¹⁵N = δ¹⁵Nconsumer − δ¹⁵Nfood source), however, research has shown mixed results in the magnitude and the direction of the change. This is potentially more complex for omnivores wh...

Full-text available
Invasion of non-native species is considered a major threat to global biodiversity. Here we present a comprehensive overview of the occurrence, richness and biomass contribution of non-native fish species in 1943 standing water bodies from 14 countries of the Western Palearctic, based on standardised fish catches by multi-mesh gillnetting. We expec...

Introduction of artificial plants may facilitate the transition from a turbid to a clear-water state in shallow lakes, particularly when plant establishment is delayed. We investigated the usefulness of artificial plants as a restoration tool in an experimental setup mimicking open submerged plant beds with high plant density [80%, HPD] and low pla...

Summary 1. Carbon (C) and nitrogen (N) stable isotope composition (15N:14N, d15N and 13C:12C, d13C) have been widely used to elucidate changes in aquatic ecosystem dynamics created by eutrophication and climate warming, often, however, without accounting for seasonal variation. 2. Here, we aim to determine the factors controlling the stable isotope...
Article
Full-text available
The importance of allochthonous versus authochthonous carbon in the diet of zooplankters has been discussed at length in the recent literature, the more so for lakes with dissolved organic matter (DOM) concentrations between 3.5 and 25 mg L−1. Here, we investigated the sources of carbon for Boeckella gracilipes (Copepoda, Calanoida) in three Patago...

We studied nutrient limitation of periphytic algae (henceforth periphyton) in 24 mesocosms simulating shallow lakes with two nutrient levels, enriched (with added nitrogen, N, and phosphorus, P) and unenriched (control), and three temperature scenarios, ambient, A2 from the Intergovernmental Panel on Climate Change (IPCC) and A2 + 50%. Periphyton g...

1. We followed microbial and other planktonic communities during a 4-month period (February–May) in 12 outdoor flow-through mesocosms designed to elucidate the effect of global warming and nutrient enrichment. The mesocosms were established in 2003. 2. Warming had a smaller effect than nutrients on the biomass of the microbial and planktonic commu...
Article
Full-text available
Eutrophication resulting from high nutrient loading has been the paramount environmental problem for lakes world-wide for the past four decades. Efforts are being made in many parts of the world to reduce external nutrient loading via improved wastewater treatment or diversion of nutrient-rich inflows. However, even after a reduction of the externa...
Article
Full-text available
Transgressive dune fields often comprise a multiplicity of landforms where vegetation processes largely affect landform dynamics, which in turn, also affect vegetation processes. These associations have seldom been studied in detail. This paper examines four separate landform types in a complex coastal transgressive dunefield located in the central...
Article

1. Filamentous green algae (FGA) may represent an alternative state in high-nutrient shallow temperate lakes. Furthermore, a clear water state is sometimes associated with the dominance of FGA; however, the mechanisms involved remain uncertain. 2. We hypothesised that FGA may promote a clear water state by directly suppressing phytoplankton growth,...

North Andean Patagonian aquatic systems include a number of deep and shallow oligotrophic lakes with a profuse hydrographic net. In this contribution we present a review of the researches carried out during the last decade in the food webs of North Patagonian water bodies. Food webs in these systems were studied based on field surveys, combining wi...

We assessed the importance of temperature, salinity, and predation for the size structure of zooplankton and provided insight into the future ecological structure and function of shallow lakes in a warmer climate. Artificial plants were introduced in eight comparable coastal shallow brackish lakes located at two contrasting temperatures: cold-tempe...

1. Zooplankton may react differently to chemical signals produced by macrophytes in shallow systems. They may be attracted by macrophytes, as the plants may be used as a refuge against predators, or the plants may have a repellent effect (e.g. when the plants are a habitat for numerous invertebrate predators or fish). In fishless Patagonian ponds,...

The turbellarian predator Mesostoma ehrenbergii, a common inhabitant of fishless ponds of northern Patagonia, can consume prey larger than 1 mm. Because the feeding strategy of M. ehrenbergii includes mucus trapping and external digestion, this predator may exploit a broad range of prey sizes. We hypothesize that M. ehrenbergii could exert a strong...

Patagonia fishless ponds have been stocked with fishes for recreational purposes since early in the 20th century. We carried out a summer plankton sampling in 18 Patagonian lakes; 12 fishless, 5 with introduced fishes and 1 with endemic fish fauna. The lakes are sit-uated on a latitudinal gradient from 39° to 49°S. Zooplankton and phytoplankton com...

The zooplanktivorous flatworm Mesostoma ehrenbergii and the calanoid copepod Boeckella gracilis were observed to coexist in Patagonian fishless ponds. In laboratory experiments, we studied the vulnerability of B. gracilis to M. ehrenbergii predation, testing the attack rates on copulating pairs and single adults in different abundances. We also det...

Full-text available
Through laboratory experiments, we analysed the influence of spatial heterogeneity on predation by Mesostoma ehrenbergii on the calanoid Boeckella gracilis and the cyclopoid Acanthocyclops robustus in four horizontal and two vertical spatial arrangements. This spatial heterogeneity simulated that of Juncaceae stems, a major macrophyte in the natura...

The importance of fungi and bacteria attached to leaf litter in the diet and growth of shredders in flowing waters is well-documented. This study focuses on the role of microorganisms colonizing submerged leaf litter in the diet and growth ofVerger cf.limnophilus (Trichoptera: Limnephilidae) larvae in a Patagonian Andean temporary pond (Fantasma po...
