Species lifetime distribution for simple models of ecologies [PDF]

Proceedings of the National Academy of Sciences, 2005
Interpretation of empirical results based on a taxa's lifetime distribution shows apparently conflicting results. Species' lifetime is reported to be exponentially distributed, whereas higher-order taxa, such as families or genera, follow a broader distribution, compatible with power-law decay.

The influence of spatial errors in species occurrence data on distribution models

, 2008
1. Species distribution modelling is used increasingly in both applied and theoretical research to predict how species are distributed and to understand attributes of species' environmental requirements.

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

, 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.

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

MethodsX
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 ...

Mapping the Abundance of Multipurpose Agroforestry Faidherbia albida Trees in Senegal

Remote Sensing, 2022
Multi-purpose Faidherbia albida trees represent a vital component of agroforestry parklands in West Africa as they provide resources (fodder for livestock, fruits and firewood) and support water lifting and nutrient recycling for cropping.

Hierarchical Species Distribution Models [PDF]

Current Landscape Ecology Reports, 2016
Determining the distribution pattern of a species is important to increase scientific knowledge, inform management decisions, and conserve biodiversity. To infer spatial and temporal patterns, species distribution models have been developed for use with many sampling designs and types of data.

Effects of sample size on the performance of species distribution models

, 2008
A wide range of modelling algorithms is used by ecologists, conservation practitioners, and others to predict species ranges from point locality data. Unfortunately, the amount of data available is limited for many taxa and regions, making it essential ...

Potential distribution range of invasive plant species in Spain [PDF]

, 2012
Success of invasive species has been frequently estimated as the present distribution range size in the introduced region. However, the present distribution range is only a picture of the invasion for a given time step and do not inform on the potential ...

Caveats for correlative species distribution modeling

Ecological Informatics, 2015
Abstract Correlative species distribution models are becoming commonplace in the scientific literature and public outreach products, displaying locations, abundance, or suitable environmental conditions for harmful invasive species, threatened and endangered species, or species of special concern.

Modelling the distribution of the invasive Roesel’s bushcricket (Metrioptera roeselii) in a fragmented landscape [PDF]

, 2011
The development of conservation strategies to mitigate the impact of invasive species requires knowledge of the species ecology and distribution. This is, however, often lacking as collecting biological data may be both time-consuming and resource ...
