The use of an integrated framework combining eco-evolutionary data and species distribution models to predict range shifts of species under changing climates

open access: yesMethodsX
Species distribution models (SDMs) are powerful tools that can predict potential distributions of species under climate change. However, traditional SDMs that rely on current species occurrences may underestimate their climatic tolerances and potential ...

A Robust Prediction Model for Species Distribution Using Bagging Ensembles with Deep Neural Networks

open access: yesRemote Sensing, 2021
Species distribution models have been used for various purposes, such as conserving species, discovering potential habitats, and obtaining evolutionary insights by predicting species occurrence. Many statistical and machine-learning-based approaches have

The Relative Influences of Climate and Competition on Tree Growth along Montane Ecotones in the Rocky Mountains

open access: yes, 2016
Distribution shifts of tree species are likely to be highly dependent upon population performance at distribution edges. Understanding the drivers of aspects of performance, such as growth, at distribution edges is thus crucial to accurately predicting ...

Modelling the spatial distribution of three marine fish species in the southern Benguela [PDF]

open access: yes, 2013
Understanding the spatial distribution of species in relationship to climatic and environmental variables is key to conservation and management of important species, as their distribution might change under climate change and variability.

Analytic solution of Hubbell's model of local community dynamics

open access: yes, 2003
Recent theoretical approaches to community structure and dynamics reveal that many large-scale features of community structure (such as species-rank distributions and species-area relations) can be explained by a so-called neutral model.

Ecological status and spatial extent of non-native shrubs Lantana camara L. and Ageratina adenophora Sprengel in the forest communities of western Himalaya

open access: yesTrees, Forests and People
This research elucidates the ecological status and spatial extent of two non-native invasive species, Lantana camara L. and Ageratina adenophorum Sprengel, within dominant forest communities across an altitude gradient in the western Himalayan region ...

Cascading predictions from common to uncommon species improves species distribution models for plants

open access: yesEcological Informatics
Species distribution models (SDMs) traditionally rely on abiotic factors like climate and topography to predict plant species distributions. While effective at broad scales, these models often fail at finer spatial resolutions due to their inability to ...

Diversity waves in collapse-driven population dynamics [PDF]

open access: yes, 2015
Populations of species in ecosystems are often constrained by availability of resources within their environment. In effect this means that a growth of one population, needs to be balanced by comparable reduction in populations of others.

Spatio-temporal patterns of an invasive species Mimosa bimucronata (DC.) Kuntze under different climate scenarios in China

open access: yesFrontiers in Forests and Global Change, 2023
Invasive alien plants pose a serious threat to native ecosystems and their biodiversity. To control their spread and damage, it is critical to clarify the potential distribution patterns of the invaders at the regional scale and their response to climate

Trends and biases in global scientific literature about ecological niche models

open access: yesBrazilian Journal of Biology
Recently, ecological niche models have been employed to investigate the potential geographical distribution of species. However, it is necessary to analyze the vast number of publications on this topic to understand the trends and biases of research ...
