Marine trophic architecture and hidden ecological connections in the Strait of Magellan: keystone species and ecosystem resilience

Oikos, EarlyView.
Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

Multidimensional upwind methods for hyperbolic conservation laws [PDF]

Journal of Computational Physics, 1990
A class of conservative difference algorithms for hyperbolic conservation laws in several space variables which do not make use of operator splitting are presented. These methods are upwind and multidimensional, in that the numerical fluxes are obtained by solving the characteristic form of the full multidimensional equations at the zone edge and that ...

Magnetohydrodynamic regime of the born-infeld electromagnetism

, 2017
The Born-Infeld (BI) model is a nonlinear correction of Maxwell's equations. By adding the energy and Poynting vector as additional variables, it can be augmented as a 10$\times$10 system of hyperbolic conservation laws, called the augmented BI (ABI ...

Urban wild meat and pangolin consumption across southern forested Cameroon: The limited influence of COVID‐19

People and Nature, EarlyView.
Abstract Overexploitation of wildlife is pervasive in many tropical regions, and in addition to being a significant conservation and sustainability concern, it has received global attention given discussions over the origins of zoonotic disease outbreaks.

Investigating conservation performance payments alongside human–wildlife conflicts: The Swedish lynx and wolverine protection policies

People and Nature, EarlyView.
Abstract Conservation performance payments are becoming an increasingly popular instrument to tackle human–wildlife conflicts. In Sweden, Sámi communities practicing reindeer husbandry receive performance payments as compensation for reindeer losses caused by lynxes and wolverines.

On Lie Symmetries of Hyperbolic Model Metric of SL(n, R) Geometry

پژوهش‌های ریاضی, 2020
Introduction ‎  Symmetries of an equation are closely related to conservation‎ laws‎. ‎Noether's theorem provides a method for finding conservation laws of differential‎ equations arising from a known Lagrangian and having a known Lie symmetry‎.

A hyperbolic conservation law and particle systems [PDF]

Journal of Difference Equations and Applications, 2011
In these notes we consider two particle systems: the totally asymmetric simple exclusion process and the totally asymmetric zero-range process. We introduce the notion of hydrodynamic limit and describe the partial differential equation that governs the evolution of the conserved quantity – the density of particles .

The magnitude and economic replacement value of wild meat obtained from ‘recreational’ big game hunting in the United States

People and Nature, EarlyView.
Abstract Meat production has notable benefits for food security, nutrition and various production economies, but has elicited substantial negative environmental impacts. Recreational hunting provides an alternative to agricultural meat production for over 24 million hunters worldwide.

Made in the shade: Leaf responses of native wildflowers to single‐axis photovoltaic solar energy

PLANTS, PEOPLE, PLANET, EarlyView.
As solar energy expands globally, balancing renewable power generation with biodiversity and ecosystem health has become an urgent challenge. This study investigated how native wildflowers respond at leaf level to the unique microclimates created by rotating solar panels in California's Central Valley.

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...
