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.

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.

Can mechanism inform species’ distribution models? [PDF]

open access: yesEcology Letters, 2010
Ecology Letters (2010) 13: 1041–1054 Abstract Two major approaches address the need to predict species distributions in response to environmental

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.

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

open access: yesE3S Web of Conferences

Meta-heuristic algorithms in car engine design: a literature survey [PDF]

open access: yes, 2015
Meta-heuristic algorithms are often inspired by natural phenomena, including the evolution of species in Darwinian natural selection theory, ant behaviors in biology, flock behaviors of some birds, and annealing in metallurgy.

Population distribution models: species distributions are better modeled using biologically relevant data partitions

open access: yesBMC Ecology, 2011
Background Predicting the geographic distribution of widespread species through modeling is problematic for several reasons including high rates of omission errors.

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.

A multi-scale distribution model for non-equilibrium populations suggests resource limitation in an endangered rodent. [PDF]

open access: yes, 2014
Species distributions are known to be limited by biotic and abiotic factors at multiple temporal and spatial scales. Species distribution models, however, frequently assume a population at equilibrium in both time and space.
