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

open access: yesPesquisa 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]

open access: yesPeerJ
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]

open access: yesInternational 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 ...

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.

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 ...

Bounding species distribution models [PDF]

open access: yesCurrent Zoology, 2011
Abstract Species distribution models are increasing in popularity for mapping suitable habitat for species of management concern. Many investigators now recognize that extrapolations of these models with geographic information systems (GIS) might be sensitive to the environmental bounds of the data used in their development, yet there is

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 ...

Species lifetime distribution for simple models of ecologies [PDF]

open access: yesProceedings 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.

Distribution modeling, soil properties, and variation in essential oils chemical composition of Rhanterium adpressum Coss. & Dur. [PDF]

open access: yes, 2019
Modeling the distribution of Rhanterium adpressum, an endemic species from southwestern Algeria, and the interactions of soil’s chemical properties with the variability of chemical composition of its essential oils makes the objective of this study ...
