Biogeography of intertidal invertebrates is influenced by latitude along the west coast of Australia

open access: yesEcography, EarlyView.
Along the west coast of Australia, intertidal rock platforms support high invertebrate diversities that provide vital ecosystem services, yet patterns in diversity are not well understood. Here, we document and examine the invertebrate assemblages on intertidal rock platforms in Western Australia and delineate ecoregions according to assemblage ...

Checklist of the Invertebrate Animals Reported from the Region of Port Aransas, Texas [PDF]

open access: yes, 1960
This checklist is of preliminary form with the hope that this will be a beginning for a more complete annotated list of the fauna and flora of this region. In many cases this list is quite obviously incomplete, however further work on the taxonomy of

Sampling effort to characterize estuarine macroinfaunal communities in patchy habitats

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Estuarine benthic macroinfauna have aggregated, patchy distributions, making accurate community measurements dependent upon sampling scales. The purpose of this study is to determine the appropriate core sizes and sampling effort needed to characterize benthic infaunal communities in Corpus Christi Bay, Texas, USA.

Benthic megafauna and the functioning of macroalgal forests and urchin barrens

open access: yesOikos, EarlyView.
Two temperate rocky reef food‐web models, representing the trophic diversity of the Mediterranean rocky reef communities, were built for the two stable states: macroalgal forests and barren grounds, which are characterized by opposite amounts of erect macroalgal biomass.

Net phytoplankton and zooplankton in the New York Bight, January 1976 to February 1978, with comments on the effects of wind, Gulf Stream eddies, and slope water intrusions [PDF]

open access: yes, 1984
Results are given of monthly net phytoplankton and zooplankton sampling from a 10 m depth in shelf, slope, and Gulf Stream eddy water along a transect running southeastward from Ambrose Light, New York, in 1976, 1977, and early 1978.

Light-Dependency of Growth and Secondary Metabolite Production in the Captive Zooxanthellate Soft Coral Sinularia flexibilis [PDF]

open access: yes
The branching zooxanthellate soft coral Sinularia flexibillis releases antimicrobial and toxic compounds with potential pharmaceutical importance. As photosynthesis by the symbiotic algae is vital to the host, the light-dependency of the coral, including

Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

Methods of conceptual clustering and their relation to numerical taxonomy [PDF]

open access: yes, 1985
Artificial Intelligence (AI) methods for machine learning can be viewed as forms of exploratory data analysis, even though they differ markedly from the statistical methods generally connoted by the term.
