TLDR
In this paper, a stochastic-dynamic model was proposed to simulate dung production and degradation in order to estimate the contribution of dung beetles to dual-purpose cattle production in the tropical grasslands of Veracruz, Mexico.About:

Economic and Environmental Impacts of Harmful Non-Indigenous Species in Southeast Asia
TL;DR: In this paper, the authors used benefit-cost analysis embedded in a Monte-Carlo simulation model and analyzed economic and environmental impacts of NIS in the region to estimate the total burden of non-indigenous species (NIS) in Southeast Asia.

Populations and assemblages living on the edge: dung beetles responses to forests-pasture ecotones.
TL;DR: It is proposed that conservation efforts in human-managed landscapes should focus on mitigating current and delayed edge effects of dung beetle populations and assemblage parameters through gradients in forest-pasture ecotones.
Journal ArticleDOI
Tree retention in cattle ranching systems partially preserves dung beetle diversity and functional groups in the semideciduous Atlantic forest: the role of microclimate and soil conditions.
TL;DR: Results confirm that cattle ranching with tree retention preserves dung beetle diversity, and suggest that cattle systems without canopy cover have higher impact (negative effects) than silvopastoral systems on both species and functional groups.
Journal ArticleDOI
Canopy cover is a key factor to preserve the ecological functions of dung beetles in the southern Atlantic Forest
TL;DR: In this paper, the authors explored the influence of canopy cover on dung beetle biomass, their burial activity and changes in soil conditions associated with this activity, in the southern Atlantic Forest of Argentina.

Dung Beetle Body Condition: A Tool for Disturbance Evaluation in Contaminated Pastures.
Sebastián Villada-Bedoya,Alex Córdoba-Aguilar,Federico Escobar,Imelda Martínez-Morales,Daniel Gonzalez-Tokman +4 more
TL;DR: It is provided the first evidence under natural conditions that native and exotic species of dung beetles are highly sensitive to different types of livestock management, with veterinary medications and herbicides having the ability to alter body condition.

A comparison of three methods for selecting values of input variables in the analysis of output from a computer code
TL;DR: In this paper, two sampling plans are examined as alternatives to simple random sampling in Monte Carlo studies and they are shown to be improvements over simple sampling with respect to variance for a class of estimators which includes the sample mean and the empirical distribution function.

What are Ecosystem Services? The Need for Standardized Environmental Accounting Units
TL;DR: In this article, the authors argue that the term "ecosystem services" is too ad hoc to be of practical use in welfare accounting and propose a definition, rooted in economic principles, of ecosystem service units.

Risk Analysis: A Quantitative Guide
TL;DR: In this article, the authors present a risk analysis approach based on Monte-Carlo simulation, which is used to fit a first-order parametric distribution to observed data and then combine it with a second-order probability distribution.

The Economic Value of Ecological Services Provided by Insects
John E. Losey,Mace Vaughan +1 more
TL;DR: The annual value of these ecological services provided by insects to the United States is estimated to be at least $57 billion, an amount that justifies greater investment in the conservation of these services.
