Evaluating the ecological realism of plant species distribution models with ecological indicator values [PDF]

open access: yes, 2020
Species distribution models (SDMs) are routinely applied to assess current as well as future species distributions, for example to assess impacts of future environmental change on biodiversity or to underpin conservation planning.

Assessing the freshwater distribution of yellow eel [PDF]

open access: yes, 2008
In the global context of the decline in wild species, modeling the distribution of populations is a crucial aspect of ecological management. This can be a major challenge, especially for species, such as the European eel, that have complex life cycles ...

Modeling of the potential distribution of Eichhornia crassipes on a global scale: risks and threats to water ecosystems

open access: yesRevista Ambiente & Água, 2020
The water hyacinth (Eichhornia crassipes) is listed among the 100 worst invasive plants and was ranked as the 11th worst invasive species in Europe, being a threat to aquatic biodiversity and water-provision.

Used-habitat calibration plots: a new procedure for validating species distribution, resource selection, and step-selection models [PDF]

open access: yes, 2018
“Species distribution modeling” was recently ranked as one of the top five “research fronts” in ecology and the environmental sciences by ISI's Essential Science Indicators (Renner and Warton 2013), reflecting the importance of predicting how species ...

Impact of Habitat Loss and Mining on the Distribution of Endemic Species of Amphibians and Reptiles in Mexico

open access: yesDiversity, 2019
Mexico holds an exceptional diversity and endemicity of amphibian and reptile species, but several factors pose a threat to their conservation. Here, we produced ecological niche models for 179 Mexican endemic amphibian and reptile species and examined ...

Comparing sample bias correction methods for species distribution modeling using virtual species

open access: yesEcosphere, 2021
A key assumption in species distribution modeling (SDM) with presence‐background (PB) methods is that sampling of occurrence localities is unbiased and that any sampling bias is proportional to the background distribution of environmental covariates ...

Predicting extinctions with species distribution models

open access: yesCambridge Prisms: Extinction, 2023
Abstract Predictions of species-level extinction risk from climate change are mostly based on species distribution models (SDMs). Reviewing the literature, we summarise why the translation of SDM results to extinction risk is conceptually and methodologically challenged and why critical SDM assumptions are unlikely to be met under ...

Markov chain approach to the distribution of ancestors in species of biparental reproduction [PDF]

open access: yes, 2014
We studied how to obtain a distribution for the number of ancestors in species of sexual reproduction. Present models concentrate on the estimation of distributions repetitions of ancestors in genealogical trees. It has been shown that is not possible to

Modelling species distributions using regression quantiles [PDF]

open access: yesJournal of Applied Ecology, 2007
Summary Species distribution modelling is an important and well‐established tool for conservation planning and resource management. Modelling techniques based on central estimates of species responses to environmental factors do not always provide ecologically meaningful estimates of species–environment relationships and are being increasingly ...

Modelling the distribution of large branchiopods (Crustacea: Notostraca, Anostraca & Spinicaudata) for predicting occurrences in poorly sampled regions

open access: yesGlobal Ecology and Conservation, 2020
Large branchiopods are one of the most iconic species groups in temporary pools. Due to their specific biology and massive habitat degradation, they are one of the most threatened freshwater species groups.
