Occupancy, spatial variance, and the abundance of species [PDF]

open access: yes, 2003
A notable and consistent ecological observation known for a long time is that spatial variance in the abundance of a species increases with its mean abundance and that this relationship typically conforms well to a simple power law (Taylor 1961 ...

Migration alters oscillatory dynamics and promotes survival in connected bacterial populations [PDF]

open access: yes, 2019
Migration influences population dynamics on networks, thereby playing a vital role in scenarios ranging from species extinction to epidemic propagation.

Phylogeography of Tenebrionid beetles in the Aegean archipelago

open access: yes, 2010
The Aegean archipelago, which has a mostly continental origin, provides a ‘natural laboratory’ to explore the effects of dispersal limitation on population and community structure.

Species abundance distribution results from a spatial analogy of central limit theorem [PDF]

open access: yes, 2013
Copyright © 2009, The National Academy of SciencesThe frequency distribution of species abundances [the species abundance distribution (SAD)] is considered to be a fundamental characteristic of community structure.

Introducing untb, an R Package For Simulating Ecological Drift Under the Unified Neutral Theory of Biodiversity [PDF]

open access: yes
The distribution of abundance amongst species with similar ways of life is a classical problem in ecology. The unified neutral theory of biodiversity, due to Hubbell, states that observed population dynamics may be explained on the assumption of per ...

open access: yes, 2019
The study of biodiversity has grown exponentially in the last thirty years in response to demands for greater understanding of the function and importance of Earth's biodiversity and finding solutions to conserve it.

The accelerating influence of humans on mammalian macroecological patterns over the late Quaternary [PDF]

open access: yes, 2019
The transition of hominins to a largely meat-based diet ~1.8 million years ago led to the exploitation of other mammals for food and resources. As hominins, particularly archaic and modern humans, became increasingly abundant and dispersed across the ...
