Metacommunity ecology describes community organisation considering both environmental and spatial processes. We tested the relative importance of environmental and spatial factors on spring ostracod assemblages from four European regions characterised by different climatic conditions (e.g. aridity). Pure and shared effects of environment and space ...

Timely identification of endangered populations is vital to save them from extirpation. Here we tested whether six commonly used early-warning metrics are useful predictors of impending extirpation in laboratory rotifer (Brachionus calyciflorus) populations. To this end, we cultured nine rotifer clones in a constant laboratory environment, in which...

Copepods are the most numerous metazoans in water-filled phytotelmata formed by Heliconia and Calathea floral bracts in cloud forests of Cordillera de la Costa, Northern Venezuela. We estimated the potential effect of copepods on ciliate community structure in this habitat with a laboratory experiment. Predation effects of five life stages of a har...

The crayfish plague pathogen, Aphanomyces astaci, is a fungal-like organism (Oomycetes), specialized in parasitizing freshwater crayfish species. Crayfish plague is a disease that has caused losses of indigenous crayfish populations, especially in Europe. The pathogen chronically infects North American endemic crayfish, such as Procambarus clarkii,...

Little is known on cubomedusae population structure, and what is known for many species is mostly from rare occurrences or from a metapopulation perspective. Knowledge on population units is critical for understanding population dynamics as well as predicting potential risk to swimmers. Otolith shape analysis is a proven stock identification techni...

We explored whether fin clips and scales can be used as potential non-lethal alternatives to muscle tissue for examining the isotopic composition of asp Leuciscus aspius, a locally threatened freshwater species. Dorsal fin clips, scales and muscle plugs were collected from two asp populations and subsequently analysed for nitrogen and carbon stable...

We present new chironomid and stable isotope (δ13C and δ15N) data from Little Llangothlin Lagoon, Australia that provides more detail on changes in this wetland since European settlement ca. 1840 AD. We also examine how the updated Holocene paleoecological record provides insights for management of this Ramsar-listed wetland. The current management...

Declining calcium concentrations and invasion by Bythotrephes longimanus are two important, often co-occurring, stressors affecting Canadian Shield lakes. However, there has been no experimental examination of how they might jointly influence zooplankton communities. We conducted a 6-week field mesocosm experiment in Havelock Lake, Haliburton, Onta...

Teleost fishes not only communicate with well-known visual cues, but also olfactory and acoustic signals. Communicating with sound has advantages, as acoustic signals propagate fast, omnidirectionally, around obstacles and over long distances. Heterogeneous environments might favour multimodal communication, especially in socially complex species, ...

One of the main assumed impacts of invasive gobies is predation on benthic macroinvertebrates. Despite numerous dietary studies, however, quantitative evaluations of impact in European river systems are scarce. Here, we investigate the impact of tubenose (Proterorhinus semilunaris, Heckel 1837) and round (Neogobius melanostomus, Pallas 1814) gobies...
