Disentangling nestedness from models of ecological complexity
Nature, 2012Complex networks of interactions are ubiquitous and are particularly important in ecological communities, in which large numbers of species exhibit negative (for example, competition or predation) and positive (for example, mutualism) interactions with one another. Nestedness in mutualistic ecological networks is the tendency for ecological specialists

Toward ecologically explicit null models of nestedness
Oecologia, 2007A community is "nested" when species assemblages in less rich sites form nonrandom subsets of those at richer sites. Conventional null models used to test for statistically nonrandom nestedness are under- or over-restrictive because they do not sufficiently isolate ecological processes of interest, which hinders ecological inference. We propose a class

Network Dynamics Contribute to Structure: Nestedness in Mutualistic Networks
Bulletin of Mathematical Biology, 2013Both ecological and evolutionary timescales are of importance when considering an ecological system; population dynamics affect the evolution of species traits, and vice versa. Recently, these two timescales have been used to explain structural patterns in host-parasite networks, where the evolution of the manner in which species balance the use of ...

Parasitology Research, 2018
(Uploaded by Plazi for the Bat Literature Project) Nested subsets occur in ecological communities when species-poor communities are subsets of larger, species-rich communities. Understanding this pattern can help elucidate species colonization abilities, extinction risks, and general structuring of biological communities.

A consumer's guide to nestedness analysis
Oikos, 2008Nestedness analysis has become increasingly popular in the study of biogeographic patterns of species occurrence. Nested patterns are those in which the species composition of small assemblages is a nested subset of larger assemblages. For species interaction networks such as plant–pollinator webs, nestedness analysis has also proven a valuable tool ...

Treaty Nestedness and Complex Security Institutions
SSRN Electronic Journal, 2007International organizations are composed of international treaties that are linked in different ways. Institutional creation, change, death, and influence are difficult to observe without understanding this fact. We call these linked treaties "treaty complexes." One way to think of the relationship between and among treaties is via the contrasting ...

Impoverishment and Nestedness in Caviomorph Assemblages
Journal of Mammalogy, 1994Comparisons of species composition in prehistoric (8.0 × 103 to 1.2 × 103 years ago) and contemporary assemblages of caviomorphs from central Chile reveal that species richness has decreased through the Holocene. The local extinction of two species, Aconaemys fuscus and Octodon bridgesi , suggests that current assemblages are impoverished and nested ...

Richness, nestedness, and randomness in parasite infracommunity structure
Oecologia, 1996Within a host population, parasite infracommunities vary in both richness and species composition. If interspecific interactions among parasites are important in shaping infracommunities, the structure of these assemblages is expected to differ from the one predicted by null models, i.e. from the one that would result from chance alone. Using data from
