A Framework to Analyze Primate Species Vulnerability to Trade in Urban Markets

American Journal of Primatology, Volume 87, Issue 12, December 2025.
A primate‐focused conservation criminology framework to examine taxon‐specific vulnerability to live trade in urban markets. ABSTRACT Live primates are increasingly commodified and appropriated as inputs into markets, both at the international and domestic scales, and across physical and online platforms.

On the solution of some simple fractional differential equations

International Journal of Mathematics and Mathematical Sciences, 1990
The differintegration or fractional derivative of complex order ν, is a generalization of the ordinary concept of derivative of order n, from positive integer ν=n to complex values of ν, including also, for ν=−n a negative integer, the ordinary n-th ...

On an explicit finite difference method for fractional diffusion equations

, 2003
A numerical method to solve the fractional diffusion equation, which could also be easily extended to many other fractional dynamics equations, is considered.

Temperature and Morphology Affect the Performance and Cost of Flight in Spruce Budworm Females

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Forewing length and wing surface are the key morphological traits to explain the biomechanics of the flight performance in spruce budworm. Large budworm females benefit from more energy reserves that can be allocated daily to flight and a relative energy saving during flight due to their mass.

Inverse Problem for a Mixed Type Integro-Differential Equation with Fractional Order Caputo Operators and Spectral Parameters

Axioms, 2020
The questions of the one-value solvability of an inverse boundary value problem for a mixed type integro-differential equation with Caputo operators of different fractional orders and spectral parameters are considered.

On the relationship between mean hillslope length and drainage density

Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
How can we quantify the average hillslope length of a catchment? Here we present a new framework that links this key metric to the actual flowing length of the river network, offering a broader, flexible alternative to the Horton classical formulation to describe how hillslope structure adapts to network expansion/contraction.

Statistics of non-linear stochastic dynamical systems under L\'evy noises by a convolution quadrature approach

, 2011
This paper describes a novel numerical approach to find the statistics of the non-stationary response of scalar non-linear systems excited by L\'evy white noises.

Surviving the winds through pattern formation: Mathematical modelling of heather stripes in Scotland

Journal of Ecology, Volume 113, Issue 12, Page 3510-3521, December 2025.
Heather (Calluna vulgaris) and bare soil sometimes form striking patterns in Scottish windy environments. Our simple mathematical model shows that interactions between vegetation, soil and wind—particularly local erosion reduction by plants and upwind shelter of plants by microtopography—are sufficient to generate these self‐organised patterns and ...

Spectral function of the Anderson impurity model at finite temperatures

, 2010
Using the functional renormalization group (FRG) and the numerical renormalization group (NRG), we calculate the spectral function of the Anderson impurity model at zero and finite temperatures.
