Modeling Invasive Plant Species in Kenya’s Northern Rangelands

Frontiers in Environmental Science, 2020
Kenya is composed of diverse geographic regions and is heavily impacted by climatic variability. Habitat heterogeneity has led to a diverse number of plants and animals. Invasive species, however, threaten this biodiversity. This study mapped the current

Community Confounding In Joint Species Distribution Models [PDF]

Scientific Reports, 2021
Abstract Joint species distribution models have become ubiquitous for studying species-habitat relationships and dependence among species. Accounting for community structure often improves predictive power, but can also alter inference on species-habitat relationships.

Future uncertainties for the distribution and conservation of Paubrasilia echinata under climate change [PDF]

Acta Botânica Brasílica, 2019
Paubrasilia echinata is a widely cultivated endangered tree species with small populations restricted to a narrow strip of habitats along the Brazilian coast. The potential impacts of climate change on the distribution of P.

Range map datasets for terrestrial vertebrates across Taiwan

Data in Brief, 2022
Accurate data describing the geographic distribution of specific species form the basis for effective conservation management policies. However, for most species the freely available distributional information is usually confined to either expert maps or

Monotonicity-constrained species distribution models [PDF]

Ecology, 2011
Flexible modeling frameworks for species distribution models based on generalized additive models that allow for smooth, nonlinear effects and interactions are of increasing importance in ecology. Commonly, the flexibility of such smooth function estimates is controlled by means of penalized estimation procedures.

Predicting extinctions with species distribution models

Cambridge 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 ...

Zoning for edaphoclimatic aptitude of Bambusa vulgaris and Dendrocalamus giganteus in Brazil

Pesquisa Agropecuária Tropical, 2019
The use of renewable materials and more sustainable processes are essential to minimize the negative impacts of population growth. Bamboo is a viable alternative, because it is a product with potential properties for wood replacement. However, to achieve

Geographic patterns of distribution and ecological niche of the snake-necked turtle genus Hydromedusa [PDF]

PeerJ
Biotic and abiotic factors play a crucial role in determining the distribution of species. These factors dictate the conditions that must be met for a species to thrive in a particular area.

Delineating generalized species boundaries from species distribution data and a species distribution model [PDF]

International Journal of Geographical Information Science, 2013
Species distribution models (SDM) are commonly used to provide information about species ranges or extents, and often are intended to represent the entire area of potential occupancy or suitable habitat in which individuals occur. While SDMs can provide results over various geographic extents, they normally operate within a grid and cannot delimit ...
