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.

An updated understanding of Texas bumble bee (Hymenoptera: Apidae) species presence and potential distributions in Texas, USA [PDF]

open access: yesPeerJ, 2017
Texas is the second largest state in the United States of America, and the largest state in the contiguous USA at nearly 700,000 sq. km. Several Texas bumble bee species have shown evidence of declines in portions of their continental ranges, and ...

Predictive distribution modeling of Swertia bimaculata in Darjeeling-Sikkim Eastern Himalaya using MaxEnt: current and future scenarios

open access: yesEcological Processes, 2021
Background As global temperatures continue to rise, species distribution modeling is a suitable tool for identifying rare and endangered species most at risk of extinction, along with tracking shifting geographical range.

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

Modeling the effect of climate change to the potential invasion range of Piper aduncum Linnaeus [PDF]

open access: yesGlobal Journal of Environmental Science and Management, 2018
The potential effect of invasive plant species on biodiversity is one of most important subject of inquiry at present. In many parts of the world, the alarming spread of these plants has been documented.

Incorporating spatial correlations into multispecies mean-field models [PDF]

open access: yes, 2013
In biology, we frequently observe different species existing within the same environment. For example, there are many cell types in a tumour, or different animal species may occupy a given habitat.

Predicting the present-day distribution of Elphidium crispum through species distribution modeling [PDF]

open access: yesE3S Web of Conferences
Benthic foraminifera are widely recognized as sensitive bioindicators of marine environmental conditions, yet their large-scale ecological niches remain poorly quantified.

Environmental Information: Placing Biodiversity Phenomena in an Ecological and Environmental Context [PDF]

open access: yes, 2005
Environmental models are increasingly being used as surrogates to determine plant and animal species’ distributions for a range of uses. This use of models has become an important part of the recent science that has become known as biodiversity ...

Niche variability and its consequences for species distribution modeling. [PDF]

open access: yesPLoS ONE, 2012
When species distribution models (SDMs) are used to predict how a species will respond to environmental change, an important assumption is that the environmental niche of the species is conserved over evolutionary time-scales. Empirical studies conducted

Assessing the impact of the proposed Poyang lake hydraulic project on the Yangtze finless porpoise and its calves

open access: yesEcological Indicators, 2021
The Yangtze finless porpoise has become as significant indicator of current ecological conservation effectiveness in Poyang Lake, where nearly half of the population is found.
