Cross-scale habitat structure driven by coral species composition on tropical reefs

Scientific Reports, 2017
The availability of habitat structure across spatial scales can determine ecological organization and resilience. However, anthropogenic disturbances are altering the abundance and composition of habitat-forming organisms.

Complexity of independency and cliquy trees [PDF]

, 2020
An independency (cliquy) tree of an -vertex graph is a spanning tree of in which the set of leaves induces an independent set (clique). We study the problems of minimizing or maximizing the number of leaves of such trees, and fully characterize their ...

Flat and complex temperate reefs provide similar support for fish: Evidence for a unimodal species-habitat relationship.

PLoS ONE, 2017
Structural complexity, a form of habitat heterogeneity, influences the structure and function of ecological communities, generally supporting increased species density, richness, and diversity. Recent research, however, suggests the most complex habitats

Species Composition and Functional Traits of Macrofauna in Different Mangrove Habitats in the Persian Gulf

Frontiers in Marine Science, 2020
Macrofauna play a key role in the functioning of mangrove ecosystems. Nevertheless, our understanding of the diversity and functional structure of macrofaunal communities across different habitats in the mangrove forests of the Persian Gulf is limited ...

Exploitative Competition and Risk of Parasitism in Two Host Ant Species: The Roles of Habitat Complexity, Body Size, and Behavioral Dominance

Psyche: A Journal of Entomology, 2012
Habitat structural complexity can slow resource discovery by ants but can also lower the risk of parasitism during foraging. The relative importance of these two ecological facets of habitat complexity may differ in a species-specific manner and thus may

MICROHABITAT USE AND MULTIVARIATE PATTERN OF MOTILE EPIFAUNAL COMMUNITY IN RELATION TO SEDIMENT GRAIN SIZE IN A TROPICAL SEAGRASS MEADOW

Gestión y Ambiente, 2008
The relationship between habitat physical structure and motile epifauna community associated to a Seagrass bed dominated by Thalassia testudinum was study over the isobaths of 1 and 3 m, in terms of species diversity, organisms density, micro habitat use

Complexity in Plasma - A Grand View of Self- Organization

, 1994
"The central theme of the Complexity is the inquest of the creation of ordered structure in nature. Extensive computer simulations on plasmas have revealed that self-organization is governed by the three key processes, i.e.

Multiple habitat associations: the role of offsite habitat in determining onsite avian species density [PDF]

, 2012
Many animal populations continue to decline despite occurring in protected areas or on sympathetically managed sites. Frequently, this is because a specific habitat patch may not fulfil all the niche requirements of a threatened species.
