The relationship between species replacement, dissimilarity derived from nestedness, and nestedness [PDF]

open access: yesGlobal Ecology and Biogeography, 2012
ABSTRACTAim  Beta diversity can be partitioned into two components: dissimilarity due to species replacement and dissimilarity due to nestedness (Baselga, 2010, Global Ecology and Biogeography, 19, 134–143). Several contributions have challenged this approach or proposed alternative frameworks.

Complimentary analysis of metacommunity nestedness and diversity partitioning highlights the need for a holistic conservation strategy for highland lake fish assemblages

open access: yesGlobal Ecology and Conservation, 2015
Metacommunity nestedness can be affected by both idiosyncratic species and species turnover, and diversity partitioning allows one to separate turnover and nested components within β-diversity. Thus, complimentary analysis of metacommunity nestedness and

Measuring nestedness: A comparative study of the performance of different metrics

open access: yesEcology and Evolution, 2020
Nestedness is a property of interaction networks widely observed in natural mutualistic communities, among other systems. A perfectly nested network is characterized by the peculiarity that the interactions of any node form a subset of the interactions ...

Mutualism supports biodiversity when the direct competition is weak [PDF]

open access: yes, 2016
A key question of theoretical ecology is which properties of ecosystems favour their stability and help maintaining biodiversity. This qu estion recently reconsid- ered mutualistic systems, generating intense controversy about the role of mutu- alistic ...

Differential temporal beta‐diversity patterns of native and non‐native arthropod species in a fragmented native forest landscape [PDF]

open access: yes, 2018
An important factor that hinders the management of non‐native species is a general lack of information regarding the biogeography of non‐natives, and, in particular, their rates of turnover.

Human Impacts and Climate Change Influence Nestedness and Modularity in Food-Web and Mutualistic Networks. [PDF]

open access: yesPLoS ONE, 2016
Theoretical studies have indicated that nestedness and modularity-non-random structural patterns of ecological networks-influence the stability of ecosystems against perturbations; as such, climate change and human activity, as well as other sources of ...

Community Assembly Reveals How Environmental Controls Over Rodent Competition Drive Deer Mouse Density and Hantavirus Infection [PDF]

open access: yesEcol Lett
We examined how community assembly processes shape Sin Nombre hantavirus (SNV) dynamics in rodent communities across the southwestern United States. Environmental factors structured community composition, which regulated deer mouse abundance and SNV infection, rather than diversity alone.

Which Matrices Show Perfect Nestedness or the Absence of Nestedness? An Analytical Study on the Performance of NODF and WNODF

open access: yesBiomath, 2016
Nestedness is a concept employed to describe a particular pattern of organization in species interaction networks and in site-by-species incidence matrices.

Randomizing bipartite networks: the case of the World Trade Web [PDF]

open access: yes, 2015
Within the last fifteen years, network theory has been successfully applied both to natural sciences and to socioeconomic disciplines. In particular, bipartite networks have been recognized to provide a particularly insightful representation of many ...

Ecological networks, nestedness and sampling effort [PDF]

open access: yesJournal of Ecology, 2007
1. Ecological networks have been shown to display a nested structure. To be nested, a network must consist of a core group of generalists all interacting with each other, and with extreme specialists interacting only with generalist species. 2. Studies on ecological networks are especially prone to sampling effects, as they involve entire ...
