Social recognition in wild fish populations.
The ability of animals to gather information about their social and physical environment is essential for their ecological function. Odour cues are an important component of this information gathering across taxa. Recent laboratory studies have revealed the importance of flexible chemical cues in facilitating social recognition of fishes. These cues are known to be mediated by recent habitat ex...
متن کاملEvidence of Melanoma in Wild Marine Fish Populations
The increase in reports of novel diseases in a wide range of ecosystems, both terrestrial and marine, has been linked to many factors including exposure to novel pathogens and changes in the global climate. Prevalence of skin cancer in particular has been found to be increasing in humans, but has not been reported in wild fish before. Here we report extensive melanosis and melanoma (skin cancer...
متن کاملMolecular detection of betanodavirus in wild marine fish populations in Korea.
Viral nervous necrosis (VNN) is a worldwide disease affecting several species of cultured marine fish. In Korea, VNN has been identified in several species of cultured marine fish. In this study, the authors present data of the amplified nested polymerase chain reaction product (420 bp) of 21 nodavirus strains from different species of apparently healthy wild marine fish on the southern coast o...
متن کاملInbreeding effects in wild populations
USA. Small and isolated populations are inherently more vulnerable to external environmental perturbations and chance fluctuations in local survival and fecundity [termed ‘ENVIRONMENTAL STOCHASTICITY’ and ‘DEMOGRAPHIC STOCHASTICITY’, respectively (see Glossary)]. Are they also threatened by inbreeding and the loss of genetic diversity? With data on the effects of inbreeding in wild populations ...
متن کاملMorphological Plasticity and Phylogeny in a Monogenean Parasite Transferring between Wild and Reared Fish Populations
It is widely accepted that disease interactions between cultured and wild fish occur repeatedly, although reported cases have mainly relied just on the observation of similar symptoms in affected populations. Whether there is an explicit pathogen transfer between fish stocks, or each develops its own pathogen population, has been insufficiently studied and rarely supported by molecular tools. I...
