Open AccessAn epidemiological model for proliferative kidney disease in salmonid populations
Proliferative kidney disease (PKD) affects salmonid populations in European and North-American rivers. It is caused by the endoparasitic myxozoan Tetracapsuloides bryosalmonae, which exploits freshwater bryozoans...

Overland transport of recreational boats as a spreading vector of zebra mussel Dreissena polymorpha
In aquatic ecosystems invasive species are among the most important threats to biodiversity worldwide. Understanding the dispersal mechanisms of aquatic invaders is very important for protection and management...

A set of new and cross-amplifying microsatellite loci for conservation genetics of the endangered stone crayfish (Austropotamobius torrentium)
Like other indigenous crayfish species in Europe, the stone crayfish (Austropotamobius torrentium) is endangered due to habitat degradation, competition with invasive American crayfish and a deadly disease (crayf...

Participatory rural appraisal of ecosystem services of wetlands in the Amazonian Piedmont of Colombia: elements for a sustainable management concept
Considering the rapid changes in land use in tropical countries and the difficulties of law enforcement in remote areas, management of ecosystems benefits from the landscape approach. Within the landscape appr...

Open AccessLarge variation in mitochondrial DNA of sexual and parthenogenetic Dahlica triquetrella (Lepidoptera: Psychidae) shows multiple origins of parthenogenesis
Obligate parthenogenesis is relatively rare in animals. Still, in some groups it is quite common and has evolved and persisted multiple times. These groups may provide important clues to help solve the ‘parado...

Wetland Habitat Diversity in the Amazonian Piedmont of Colombia
Management of wetlands is often constrained by lack of a precise typology of habitats. Regional landscape attributes need to be considered in the integrative research of wetlands to allow habitat-specific mana...

Natural range expansion and human-assisted introduction leave different genetic signatures in a hermaphroditic freshwater snail
Colonization events like range expansion or biological invasions can be associated with population bottlenecks. Small population size may lead to loss of genetic diversity due to random genetic drift, to loss ...

Open AccessBottlenecks drive temporal and spatial genetic changes in alpine caddisfly metapopulations
Extinction and re-colonisation of local populations is common in ephemeral habitats such as temporary streams. In most cases, such population turnover leads to reduced genetic diversity within populations and ...

Effect of environmental stress on clonal structure of Eucypris virens (Crustacea, Ostracoda)
Environmental stress imposes strong natural selection on clonal populations, promoting evolutionary change in clonal structure. Environmental stress may also lead to reduction in population size, which togethe...

Open AccessContribution of parental and school personnel smoking to health risk behaviours among Finnish adolescents
This study compared parental smoking with school personnel smoking in relation to adolescents' smoking behaviours, alcohol use, and illicit drug use.

Effects of growth factors and water source on laboratory cultures of a northern Asellus aquaticus (Isopoda) population
We tested whether two vitamin-based supplements, bright light or water from three different sources affected the survival and reproduction of Asellus aquaticus isopods, and the growth and survival of their labora...

Evolution of Strategies to Stay in the Game
Life-history evolution is a complex process. Life-history theory covers the fundamental level of the process, the evolution of life-history traits. Life-history traits interact; those coevolving as a response ...

Phenotypic Correlation of Juvenile Growth Rate between Different Consecutive foraging Environments in a Salmonid fish: A Field Experiment
Many organisms occupy considerably different environments during individual's lifespan. We are interested in how the phenotypic characteristics that are favourable in the earlier environment predict fitness in...

Does habitat-specific variation in trematode infection risks influence habitat distribution of two closely related freshwater snails?
Parasitism may be an important factor determining the geographic distribution of closely related species. A habitat-specific risk of parasitism may lead to exclusion of susceptible host types from parasite-ri...

Within-season reproductive and somatic energy allocation in a freshwater clam, Anodonta piscinalis
The effect of a change in the environment on reproductive and somatic energy allocation in an iteroparous freshwater clam Anodonta piscinalis was studied at different time of the seasonal reproductive cycle. Envi...

Spatial variation in infection by digenetic trematodes in a population of freshwater snails (Potamopyrgus antipodarum)
Larval digenetic trematodes commonly castrate their first intermediate hosts, and should therefore impose strong selection on the timing and mode of host reproduction. Here we examine spatial variation in infe...
