Spatially structured genetic variation in a broadcast spawning bivalve: quantitative vs. molecular traits [PDF]

open access: yes, 2003
Understanding the origin, maintenance and significance of phenotypic variation is one of the central issues in evolutionary biology. An ongoing discussion focuses on the relative roles of isolation and selection as being at the heart of genetically based

The choice of a suitable sampler for benthic macroinvertebrates in deep rivers [PDF]

open access: yes, 1980
Both chemical and biological methods are used to assess the water quality of rivers. Many standard physical and chemical methods are now established, but biological procedures of comparable accuracy and versatility are still lacking.

Contents and risk assessment of heavy metals in marine invertebrates from Korean coastal fish markets.

open access: yesJournal of Food Protection, 2014
The concentrations of the heavy metals cadmium (Cd), mercury (Hg), lead (Pb), chromium, silver, nickel, copper, and zinc in the edible portions of 105 marine invertebrates representing 16 mollusk and crustacean species were accurately determined to ...

A supplement to a bibliography of samplers for benthic invertebrates [PDF]

open access: yes, 1983
A supplement to the earlier bibliography compiled by Elliott and Tullett 1978 (FBA Occas. Publ. No. 4) covering literature from December 1977 - December 1982 on samplers that could be used for the rapid removal of benthic intertebrates from the natural ...

Non-equilibrium evolution of volatility in origination and extinction explains fat-tailed fluctuations in Phanerozoic biodiversity [PDF]

open access: yesarXiv, 2017
Fluctuations in biodiversity, large and small, are pervasive in the fossil record, yet we do not understand the processes generating them. Here we extend theory from non-equilibrium statistical physics to describe the previously unaccounted for fat-tailed form of fluctuations in marine invertebrate richness through the Phanerozoic.

A Century of Copepods: The U.S. Fisheries Steamer Albatross [PDF]

open access: yes, 1999
The marine invertebrates of North America received little attention before the arrival of Louis Agassiz in 1846. Agassiz and his students, particularly Addison E. Verrill and Richard Rathbun, and Agassiz's colleague Spencer F. Baird, provided the concept
