On the methodology of feeding ecology in fish [PDF]
, 2016 Feeding ecology explains predator’s preference to some preys over others in their habitat and their competitions thereof. The subject, as a functional and applied biology, is highly neglected, and in case of fish, a uniform and consistent ...

Effective monitoring of freshwater fish [PDF]
Fish and Fisheries, 2019 AbstractFreshwater ecosystems constitute only a small fraction of the planet's water resources, yet support much of its diversity, with freshwater fish accounting for more species than birds, mammals, amphibians or reptiles. Fresh waters are, however, particularly vulnerable to anthropogenic impacts, including habitat loss, climate and land use change,

Carcinogens and Cancers in Freshwater Fishes [PDF]
Environmental Health Perspectives, 1991 Epizootics of neoplasms in freshwater fish species are considered in relation to circumstantial and experimental evidence that suggest that some epizootics of neoplasia of hepatocellular, cholangiocellular, epidermal, and oral epithelial origin may be causally related to contaminant exposure.

Veterinary Quarterly, 1996 Dust and endotoxin exposure was measured in the Spring and Autumn in 96 veterinary practitioners, subdivided in four professional groups ((predominantly working with either swine, cattle, poultry, or companion animals). Furthermore, peak expiratory flow (PEF) variability was measured four times a day over a week in Spring and Autumn in order to detect ...

Ecosystem size predicts eco-morphological variability in a postglacial diversification [PDF]
, 2017 Identifying the processes by which new phenotypes and species emerge has been a long-standing effort in evolutionary biology. Young adaptive radiations provide a model to study patterns of morphological and ecological diversification in environmental ...

Freshwater Fish Scale Database
Data in BriefScales of the ray finned fishes can be used for multiple purposes. Beside others by their specific structure and elemental composition they are usable for age determination and food-web researches. Additionally, just their presence, absence, shape, location, or numbers could provide a reliable taxonomic information. The fish scales show remarkable size

Ecology and Society, 2014 Social-ecological systems (SES) are dynamic systems that continuously change in response to internal or external pressures. A better understanding of the interactions of the social and ecological systems that drive those dynamics is crucial for the ...
