Relieving phosphorus loading is a key management tool for controlling Lake Erie eutrophication. During the 1960s and 1970s, increased inputs degraded water quality reduced central basin hypolimnetic oxygen levels which, in turn, eliminated thermal habitat vital to cold-water organisms contributed extirpation of important benthic macroinvertebrate prey species fishes. In response load reductions initiated 1972, responded quickly with water-column concentrations, phytoplankton biomass,...
Managing fisheries through rapid environmental change requires diverse approaches for identifying and adapting to novel ecological conditions. For the Wisconsin Ceded Territory, we calculated 473 adult walleye (Sander vitreus) production (P), biomass (B), P/B estimates 1990–2012. Frequency distributions statistics were right-skewed, indicating fishery is generally dominated by low populations. Mean P, B, significantly elevated in natural recruitment (NR) lakes compared with combination (NR +...
Walleye (Sander vitreus) populations are declining in Wisconsin and neighboring regions, motivating broader interest walleye biology amidst ecological change. In fishes, growth integrates variation drivers provides a signal of changing conditions. We used 23-year data set length-at-age from 353 across to test whether rates changed over time what factors best predicted these changes. Using hierarchical models, we tested spatiotemporal was related adult density (density-dependent effects),...
Six different protein-imprinted polymers using three template proteins with acidic or basic functional monomers resulted in unique fingerprints not only for the corresponding but also other proteins, allowing profiling of identification and classification.
Understanding variability in fish production, biomass, production/biomass (P/B) ratios, and their relationship to exploitation is central fisheries sustainability. At Escanaba Lake, Wisconsin, USA, data from a compulsory creel census (1965–2009) were combined with survey on populations test for empirical relationships between annual production rates of walleye (Sander vitreus). Empirical estimates relatively high temporally variable Lake. Annual P/B ratios ranges 2.4–11.3 kg·ha −1 ·year ,...
Factors affecting CH 3 Hg and Cd trophic transfer from six invertebrates a juvenile fish prey to mummichogs ( Fundulus heteroclitus ) were investigated using prey-dependent predator-dependent approaches. Prey-specific availability of metals was estimated subcellular partitioning approach (i.e., trophically available (TAM), as originally proposed by Wallace Luoma (2003) ). The proportions partitioned TAM (CH Hg-TAM%) ranged 39.7% 82.7%, while the (Cd-TAM%) 51.8% 67.4%. Hg-TAM% Cd-TAM%...
Increasing human population size and mobility have accelerated the translocation of nonnative species globally, which has become a major threat to conservation biodiversity ecosystem services. Introduced can disrupt interactions recipient ecosystem, triggering system-wide events, amplify or dampen effects existing pressures. We show how two pervasive intercontinental invasive consumers in North American lakes, dreissenids (filter-feeding mussels) Bythotrephes (carnivorous zooplankton),...
In this study, we examined bioenergetic responses of age-2+ and age-3+ mummichogs ( Fundulus heteroclitus ) to degraded habitat condition impoverished benthic prey community in polluted salt marshes by incorporating situ food consumption rates with the mercury mass balance model technique. general, appeared be more related than condition. Fish from prey-impoverished marsh (PIM) sites generally had significantly elevated total metabolic costs compared those non-prey-impoverished (NPIM) sites....

In this study, a multispecies gadget model (GadCap) simulating the interactions among Flemish Cap cod (Gadus morhua), redfish (Sebastes spp.), and shrimp (Pandalus borealis) has been incorporated as operating in management strategy evaluation (MSE) framework (a4a-FLR) to test performance of multiple combinations harvest control rules (HCRs) for three stocks when recruitment uncertainty assessment error are accounted for. The results indicate that due strong trophic interactions, it is not...
Significance Fishing down the food web occurs in oceans when mean trophic level (MTL) of fisheries’ catch declines over time. Such a trend arises if fisheries successively deplete higher-trophic species like top predators, moving on to harvest closer base such as small fish and invertebrates. Freshwater have not shown these trends. We analyzed 148 y records for an exploited lake, revealing that MTL declined during years dominated by commercial fishing but increased contemporary phase...
Living tissues modules consist of highly organized cells and extracellular matrices (ECMs) in a hierarchical manner. Among these ECMs, type I collagen (COL), which is the most abundant protein, widely accepted tissue engineering field due to its biocompatibility. However, improvement mechanical properties COL scaffolds still remains challenge. We prepared scaffold sheets with blends 2,2,6,6-tetramethylpiperidine-1-oxil(TEMPO)-oxidized cellulose nanofiber (TOCN). TOCNs high reinforced...
HIV infections among men who have sex with (MSM) are increasing in Japan.An anonymous self-administered questionnaire clients of a gay bar Osaka was used to analyse the relationship between age and unprotected anal (UAI).The highest rate UAI reported those aged ≥45 (73.3%), followed by ≤24 (60.7%), 25-34 (56.3%) 35-44 (54.0%) groups (P=0.01). In multivariate analysis, related six or more sexual partners (adjusted odds ratio (AOR), 4.88; confidence interval (CI), 1.21-19.74), bisexual...
Abstract Sustainable human exploitation of living marine resources stems from a delicate balance between yield stability and population persistence to achieve socioeconomic conservation goals. But our imperfect knowledge how oceanic oscillations regulate temporal variation in an exploited species can obscure the risk missing management targets. We illustrate applying policy suppress fluctuations fishery variable environments (prey density regional climate) present unintended outcomes...
