Fishes of Indiana streams: current and historic assemblage structure
Hydrobiologia, 2011 We examined Indiana fish assemblages using taxonomy and ecological categories to assess temporal shifts in community structure and recent environmental relationships. Historic (1945) and recent (1996–2007) presence/absence data were compiled by subbasin and analyzed with Nonmetric Multidimensional Scaling (NMS) ordination and by species richness ...

Hydrobiologia, 2010 The mobile fauna associated with two sympatric kelp species with different holdfast morphology (Saccorhiza polyschides and Laminaria hyperborea) was compared to test for differences in the assemblage structure of holdfast-associated mobile epifauna.

Recruitment and the structure of assemblages of fish on coral reefs
Trends in Ecology & Evolution, 1988Much recent research has focused on the question of the high species richness and population densities of fish inhabiting coral reefs. Both density-dependent (post-recruitment) and density-independent (pre-recruitment) processes have been implicated in the regulation of these assemblages. These processes may operate at a variety of spatial and temporal

The integral structure of a benthic infaunal assemblage
Journal of Experimental Marine Biology and Ecology, 2006It has been suggested that the scaling relationships of many features of the physical environment and biological traits are fractal-like, but for the marine benthic infauna certain aspects of the environment clearly are not. These include temporal features such as the cycles of annual climate, primary production and tides, and also some spatial ...

Segregation structure in Odonata assemblages follows the latitudinal gradient
Oecologia, 2020Latitude is known to deeply affect life with effects generalizable into ecological rules; the increasing species diversity toward tropics is the most paradigmatic. Several hypotheses tested patterns of biotic interactions' intensity along latitude. Negative interactions (i.e.

Structure and arrangement for loudspeaker assemblage
The Journal of the Acoustical Society of America, 1980A loudspeaker assemblage is made up of a group of cylindrical speaker housings, with a speaker mounted in each housing. A respective spacer in the form of a wedge block or angle sleeve is interposed between adjacent housings, so that housing end closures abut respective wedges. A flexible tension member passes through each speaker housing and spacer so

Morphological structure in a reef fish assemblage
Coral Reefs, 2009Two key morphological traits, horizontal gape and eye diameter, were measured in a large representative group of coral reef fishes. These morphological traits were used concurrently to assess their utility in exploring abilities of coral reef fishes at an assemblage level. A total of 1,218 specimens from 181 species found on the Great Barrier Reef were

This chapter addresses empirical facts about structure of local freshwater fish assemblages. The evolutionary (ultimate) or mechanistic (proximate, ecological) explanations for that structure are the focus of later chapters. In Chapter 1, I defined a local “assemblage” as the fishes that would be found together in one particular place or “locality ...

Ecology, 1990
The wet—forest stream fishes of Sri Lanka are segregated in ecological and morphological space. Suites of selected morphological attributes of the fishes were correlated with microhabitat and feeding ecology. Previous studies have shown that these fishes partition resources with pronounced complementarities along niche axes, a pattern consistent with ...
