Observations on the size-structure of macrofaunal assemblages
Journal of Experimental Marine Biology and Ecology, 1994Abstract When data from a number of macroalgal, seagrass and unvegetated sites were analysed, log abundance of macrofauna in different sieve size-classes was found to show a consistently linear negative relationship with log sieve size. The log abundance/log sieve-size regression coefficient, referred to as the size-dominance index G , has ...

Hunter-gatherer adaptations and assemblage structure
Journal of Anthropological Archaeology, 1987Abstract There is a growing tendency to conceive of hunter-gatherer adaptations as points on a yardstick, with foragers at one end and collectors on the other. Such a view limits our perspective and may trap anthropologists into seeing these categories as steps in an evolutionary progression. It is more productive to think of human adaptation as an N-

Species richness and assemblage structure of Trichoptera in Danish streams
Freshwater Biology, 2000SUMMARY 1. Species richness and assemblages of Trichoptera from 157 ‘pristine’ Danish lowland stream sites were analyzed, for dependence on geographical position of the sites and simple physical variables, using two way indicator species analysis and detrended correspondence analysis. 2.

Spatial Scaling of Functional Structure in Bird and Mammal Assemblages
The American Naturalist, 2013Differences in trait composition, or functional structure, of assemblages across spatial scales may stem from the ability to tolerate local conditions (environmental filters) and from assembly rules (biological filters). However, disentangling their respective roles has proven difficult, and limited generalities have emerged from research on the ...

Community structure of an estuarinemeiobenthic copepod assemblage
Estuarine and Coastal Marine Science, 1980The community organization of the meiobenthic copepods of two sub-tidallocations was compared with that of a low marsh, intertidal site in the same South Carolina estuary, over a 12 month period. Twenty-four collections of 4–8 replicate cores were gathered from the soft sediments between Spartina alterniflora plants.

Primate assemblage structure in amazonian flooded and unflooded forests
American Journal of Primatology, 2005There is considerable variation in primate species richness across neotropical forest sites, and the richest assemblages are found in western Amazonia. Forest type is an important determinant of the patterns of platyrrhine primate diversity, abundance, and biomass.

SummaryMulti‐object metalwork deposits provide the foundation block for many branches of enquiry, yet surprisingly little attention has been paid to the methodological issues that underlie their analysis and interpretation. The framework outlined here aims to circumvent some of the dangers of circular argument inherent in the concepts of metalwork ...

3D printing of complex origami assemblages for reconfigurable structures
Soft Matter, 2018Digital light processing-based 3D printing is utilized to fabricate complex 3D reconfigurable origami structures. These origami assemblages can be directly created by one-step printing of the customized photocurable elastomer.
