Nestedness in assemblages of helminth parasites of bats: a function of geography, environment, or host nestedness?

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.

NULL MODEL ANALYSIS OF SPECIES NESTEDNESS PATTERNS

Ecology, 2007
Nestedness is a common biogeographic pattern in which small communities form proper subsets of large communities. However, the detection of nestedness in binary presence-absence matrices will be affected by both the metric used to quantify nestedness and the reference null distribution.

Abundance and nestedness in interaction networks

Ecological Complexity, 2010
Abstract Nestedness is a useful metric that characterizes the generalist–specialist balance in ecological communities. Although several nestedness indices have been proposed, few have explored how species abundance per se affects their performance and the ability to detect true interaction networks. We here develop a mathematical framework that takes

A consumer's guide to nestedness analysis

Oikos, 2008
Nestedness 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 ...

Impoverishment and Nestedness in Caviomorph Assemblages

Journal of Mammalogy, 1994
Comparisons 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, 1996
Within 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
