Diet and trophic structure of fishes in the Barents Sea: between empty and full stomachs – large individual variability follows a common pattern

Journal of Fish Biology, EarlyView.
Abstract More than 27,000 stomachs from 70 species of fish were collected from the Barents Sea in 2015. Quantitative stomach content expressed relative to the body weight of the predator fish (g g−1 as %) varied by four to five orders of magnitude for six species with the largest sample size (Atlantic cod Gadus morhua, haddock Melanogrammus aeglefinus,

A third-order numerical method for solving fractional ordinary differential equations

AIMS Mathematics
In this paper, we developed a novel numerical method for solving general nonlinear fractional ordinary differential equations (FODEs). First, we transformed the nonlinear FODEs into the equivalent Volterra integral equations.

Negative Volterra Flows and Mixed Volterra Flows and Their Infinitely Many Conservation Laws [PDF]

arXiv, 2003
In this article, by means of considering an isospectral operator equation which corresponds to the Volterra lattice, and constructing opportune time evolution problems with negative powers of spectral parameter, and using discrete zero curvature representation, negative Volterra flows are proposed.

Rough PDEs for Local Stochastic Volatility Models

Mathematical Finance, EarlyView.
ABSTRACT In this work, we introduce a novel pricing methodology in general, possibly non‐Markovian local stochastic volatility (LSV) models. We observe that by conditioning the LSV dynamics on the Brownian motion that drives the volatility, one obtains a time‐inhomogeneous Markov process. Using tools from rough path theory, we describe how to precisely

Inverse problem for nonlinear partial differential equation with high order pseudoparabolic operator

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2012
We consider the questions of generalized solvability of inverse problem for nonlinear partial differential equations with high order pseudoparabolic operator by method of separation of variables.

Longer durability of host–parasite interaction increases host density

Oikos, EarlyView.
Comparing cases of parasitism and predation that lead to victim death, parasites need more time to complete victim exploitation. This longer ‘interaction durability' delays energy transfer from host to parasite. During exploitation, parasite virulence differentiates the infected from the susceptible host dynamics.

Boundedness of solutions of matrix nonlinear volterra difference equations

Discrete Dynamics in Nature and Society, 2002
Nonlinear discrete-time Volterra equations in a Euclidean space are considered. Conditions for the boundedness of solutions are established by virtue of recent estimates for the norm of the resolvent of Volterra operators.
