Relative abundance and size composition of subtidal abalone, Haliotis spp., sea urchin, Strongylocentrotus spp., and abundance of sea stars off Fitzgerald marine reserve, September 1993 [PDF]

open access: yes, 1997
Data were collected at twenty-six dive stations at seven discrete latitudes along Fitzgerald Marine Reserve (FMR). Dive stations were targeted at three stratified depth zones: shallow (6.1 m), medium (10.7 m), and deep (16.8 m) in six of the seven ...

Middlebrow Aesthetics: An Explanation and Defense

open access: yesPacific Philosophical Quarterly, EarlyView.
ABSTRACT We offer a philosophical account of the middlebrow as a theoretical category to do explanatory and critical work in aesthetics. On our account, the middlebrow ought to be understood as aspirational popular art. That is, it is art which aspires both to be popular (in a distinctive sense), and at the same time to be something more than popular ...

Morphological and biomechanical adaptations of larval mandibles in Trichoptera (Insecta)

open access: yesPhysiological Entomology, EarlyView.
Mandible morphology differs between predators and grazers: predators show pointed incisors, grazers sharp edges and setae. Mechanical properties depend on cuticle tanning, not elemental reinforcement. Functional mandible types reflect feeding strategies, with predators specialized for prey capture and grazers for scraping and collecting.

Estimating exploitable stock biomass for the Maine green sea urchin (Strongylocentrotus droebachiensis) fishery using a spatial statistics approach [PDF]

open access: yes, 2005
The objective of this study was to investigate the spatial patterns in green sea urchin (Strongylocentrotus droebachiensis) density off the coast of Maine, using data from a fishery-independent survey program, to estimate the exploitable biomass of this

Carbon and nitrogen contents depends on macroalgal species, their tissue section, and development stage

open access: yesPhycological Research, EarlyView.
SUMMARY Assessing the potential for macroalgae to function as a carbon sink (blue carbon) and nitrogen (N) assimilation is under intensive investigation. The content of elemental carbon (C) and N in macroalgae is the best indicator of their potential; however, with respect to the thallus, C and N content varies in space and time.
