Stable isotope (SI) analysis studies rely on knowledge of isotopic turnover rates and trophic-step discrimination factors. Epidermal mucus ('mucus') potentially provides an alternative SI 'tissue' to dorsal muscle that can be collected non-invasively non-destructively. Here, a diet-switch experiment using the omnivorous fish Cyprinus carpio plant- fish-based formulated feeds compared data between muscle, including their factors (as functions time T mass G, at half-life (50) equilibrium...
To help achieve effective longitudinal river connectivity, evaluation of the efficacy fishway use by upstream-migrating fishes is needed. Larinier super active baffle (SAB) fishways are relatively cheap retrofit fish passes, suitable for low-head barriers, widespread in Europe and most commonly fitted technical pass Britain. Their suitability non-salmonids, however, poorly quantified. The a 15% gradient SAB effects flow regime water temperature were tested European lamprey (Lampetra...
England's 10 national parks are renowned for their landscapes, wildlife, and recreational value. However, surface waters in the may be vulnerable to pollution from human-use chemicals, such as active pharmaceutical ingredients (APIs), because of factors like ineffective wastewater treatment, seasonal tourism, a high proportion elderly residents, presence low-flow water bodies that limit dilution. The present study determined extent API contamination English by monitoring 54 APIs 37 rivers...
Abstract Acoustic telemetry is an important tool for assessing the behavioural ecology of aquatic animals, but performance receivers can vary spatially and temporally according to changes in environmental gradients. Studies testing detection efficiency and/ or range are, therefore, data interpretation, although most thorough range-testing approaches are often costly impractical, such as use fixed sentinel tags. Here, stationary tag (from study animals that had either died expelled their...
Abstract Studies suggest the migratory behaviours of potamodromous fishes can be highly variable in barrier‐free systems, where differing movement types enable populations to exploit a wide range food and space resources. This intra‐population diversity spatial temporal resource use is important our ecological understanding fish distribution patterns population structure. Despite this, freshwater ecosystems are increasingly characterised by high levels fragmentation degradation that restrict...
Stable isotope analysis (SIA) was used to examine the isotopic relationships between dorsal muscle and fin, scale epidermal mucus in pike Esox lucius. δ13 C δ15 N varied predictably within each tissue pairing, with conversion factors calculated for surrogate tissues, enabling their application non-lethal sampling of E. lucius SIA.
Abstract Epidermal mucus (‘mucus’) is increasingly applied to fish ecological studies based on stable isotope analysis (SIA) due its non-invasive collection. However, knowledge SI turnover rates of individual remains limited, including uncertainty over how they are influenced by body sizes. Here, a diet switch experiment predicted (δ 13 C and δ 15 N) as function time using samples taken 200 days from 10 individually tagged common carp Cyprinus carpio covering two size groups. Non-linear...
Abstract Assessments of patterns animal movements are important for understanding their spatial ecology. Geostatistical models stable isotope (SI) landscapes (isoscapes) provide a complementary tool to telemetry assessing and predicting movements, but rarely applied riverine species. Often single‐isotope gradients in freshwater environments insufficiently variable high isoscape resolution at relatively fine scales. This is potentially overcome using dual‐isotope assignment procedures, thus,...
Abstract Biotelemetry is a central tool for fisheries management, with the implantation of transmitters into animals requiring refined surgical techniques that maximize retention rates and fish welfare. Even following successful surgery, long‐term post‐release survival can vary considerably, although knowledge limited many species. The aim here was to investigate post‐tagging in wild two lowland river species, common bream Abramis brama northern pike Esox lucius , their intra‐peritoneal...
Abstract Partial migration, whereby a population comprises multiple behavioural phenotypes that each have varying tendencies to migrate, is common among many animals. Determining the mechanisms by which these are maintained important for understanding their roles in structure and stability. The aim here was test temporal spatial consistency of migratory bream Abramis brama (‘bream’) population, then determine social preferences extent mixing across three successive annual spawning periods....
Abstract Native communities can resist the establishment and invasion of alien species through consumptive and/or competitive interactions. The extent resistance from freshwater fish to zebra mussels Dreissena polymorpha , a globally invasive Ponto-Caspian species, was assessed in two areas Britain using stable isotope analysis, where mixing models predicted contribution putative prey resources (including mussel) diet. Across sites only roach Rutilus rutilus were have diet contributed highly...
There are myriad of mind body health (MBH) interventions that effective for the preschool population. Supports may include, yet not limited to, journal expression, yoga, music therapy, mindfulness, video self-modeling, and muscle relaxation. These particular have resulted in positive changes preschoolers with anxiety, depression, stress, attention, as well various physical conditions. Benefits these MBH include being respect to teacher time, economically feasible, well-received by parents,...
