Abstract
Water quality indices (WQIs), which translate numerical values of several water quality characteristics of a sample into a single value, play a very important role in the monitoring, comparison and control of water quality. The WQIs of modern and post-modern times have been almost exclusively based o...

Abstract
We combine model predictions with global assessments of MTL from catches, trawl surveys and fisheries stock assessments and find that catch MTL does not reliably predict changes in marine ecosystems. Instead, catch MTL trends often diverge from ecosystem MTL trends obtained from surveys and assessme...

Abstract
We document strong bivariate and multivariate relationships among growth rate, fecundity, longevity, and overgrowth ability for six co-occurring colonial invertebrates. We find that all four of these traits are constrained to a single "fast-slow" niche axis that mechanistically relates life history...

Abstract
We evaluate how much of the observed spatial variation within a rocky intertidal metacommunity along 800 km of coastline can be explained by drift in the structure of recruits across 15 local sites. Our results show that large spatial changes in recruitment do not explain the observed spatial variat...

Ecological Applications (20)7 2010
Abstract
We conducted laboratory feeding trials and found that the leaf-shredding trichopteran, Lepidostoma liba, grew significantly slower when fed Bt maize compared to non-Bt maize, while other invertebrate taxa that we examined showed no negative effects. We also used field studies to assess the influence...

Ecological Applications (20)7 2010
Abstract
We established a fully factorial field experiment to test whether interactions among temporal patterns of two globally important anthropogenic disturbances of aquatic ecosystems (increased sediment loading and nutrient enrichment) determined the responses of stream benthic assemblages. Each disturba...

Abstract
We contrasted the interactive effects between physical disturbance and productivity to those between biological disturbance and productivity. Furthermore, to evaluate how these effects varied among different components of marine hard-substratum assemblages, analyses were done separately on algal and...

We used common carp to test whether the potential effects of an invasive species are altered across a range of species diversity in native communities. In mesocosms, treatments of zero, one, three, and six native fish species were used to represent the nested subset patterns observed in fish communi...

Abstract
We first compared the soil nematode communities of 228 individual plants belonging to eight herbaceous species. We included grass, leguminous, and non-leguminous species. Each individual plant grew intermingled with other species, but all plant species had a different nematode community. Moreover, n...

Abstract
We traced the origin of the fibulin gene family to the base of the metazoans. In invertebrates, Fibulin-1 and Hemicentin comprise the fibulin gene set. Diversification of the fibulins took place in the last common ancestor to the chordates by gene duplication of an ancestral Fibulin-1 gene. Further...

Comparative study of tumorigenesis and tumor immunity in invertebrates and nonmammalian vertebrates.

I will present evidence of neoplasia and invasive malignancy, as well as tumor immunity in invertebrates and nonmammalian vertebrates. I will also present a comparative and evolutionary view of the complex interactions between neoplasia and the host immune system. Overall, I wish to go beyond the to...

Abstract
We searched the genomes of the deuterostomes by extensive BLAST survey and phylogenetic analyses. The Galr2 and Galr3 share similar genomic structures, and most of them are composed of 2 exons and 1 intron. However, most of Galr1 are composed of 3 extrons and 2 introns. We did not detect the typical...

Abstract
Sialidases are very common in biological systems. They are found particularly in diverse virus families and bacteria, but also in protozoa, some invertebrates and mammalian. The enzymes differ in their biochemical properties, e.g., kinetics, binding affinity or substrate preference. Nevertheless, th...

Migratory fish and invertebrate samples were analyzed for polychlorinated biphenyls (PCBs) to study bioaccumulation in an urbanized estuary in the northeastern USA. Fish were also analyzed for (13)C, (15)N, and (34)S ratios. Results from several approaches (stable isotopes, total PCB concentrations,...

Biofouling (26)5 2010
Abstract
This study used a specially designed MAGPLATE system to quantify the en route survivorship and post-voyage recovery of biofouling assemblages subjected to short voyages (< 12 h) across a range of vessel speeds (slow, medium, fast; in the range 4.0-21.5 knots). The effect of hull location (bow, amids...
