Air mass factor formulation for spectroscopic measurements from satellites: Application to formaldehyde retrievals from the Global Ozone Monitoring Experiment [PDF]

, 2001
. We present a new formulation for the air mass factor (AMF) to convert slant column measurements of optically thin atmospheric species from space into total vertical columns.

Incorporating uncertainty in predictive species distribution modelling [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2012
Motivated by the need to solve ecological problems (climate change, habitat fragmentation and biological invasions), there has been increasing interest in species distribution models (SDMs). Predictions from these models inform conservation policy, invasive species management and disease-control measures. However, predictions are subject to uncertainty,

An exactly solvable coarse-grained model for species diversity

, 2012
We present novel analytical results about ecosystem species diversity that stem from a proposed coarse grained neutral model based on birth-death processes.

Invasion Status, Mechanisms, and Future Distribution Prediction of Solidago canadensis in the Trade Port Region: A Case Study of Ningbo Port, China

Plants
Trade ports are the first places where alien species invade and the source of their spread to other areas. Controlling invasions in these regions can effectively reduce invasion pressure and disrupt the spread pathways of invasive species, thereby ...

Double-distribution-function discrete Boltzmann model for combustion

, 2015
A 2-dimensional discrete Boltzmann model for combustion is presented. Mathematically, the model is composed of two coupled discrete Boltzmann equations for two species and a phenomenological equation for chemical reaction process.

Transferability of a predictive Robinia pseudacacia distribution model in northeast Slovenia

Acta Geographica Slovenica, 2016
The main goal of this study is to assess the transferability of a species distribution model (SDM) for Robinia pseudacacia (black locust) to two testing sites in the Prekmurje region in northeast Slovenia.

A seed-diffusion model for tropical tree diversity patterns

, 2012
Diversity patterns of tree species in a tropical forest community are approached by a simple lattice model and investigated by Monte Carlo simulations using a backtracking method.

The importance of climatic, topographic and edaphic variables in the distribution of yew species (Taxus baccata L.) and prioritization of areas for conservation and restoration in the north of Iran [PDF]

مجله جنگل ایران, 2020
Taxus baccata is an indigenous and valuable species of Hyrcanian Forests. According to recent studies, the presence of this species in the areas where distribution is declining; therefore, preserving and restoring this valuable species is essential.
