Assessing the complex sponge microbiota: core, variable and species-specific bacterial communities in marine sponges
TLDR
This global analysis represents the most comprehensive study of bacterial symbionts in sponges to date and provides novel insights into the complex structure of these unique associations. Expand
In situ fluxes of dissolved inorganic nitrogen from the sponge community on Conch Reef, Key Largo, Florida
We measured ammonium and nitrate plus nitrite fluxes from 14 common sponge species on a Florida Keys reef (Conch Reef) using a combination of incubation experiments and an in situ method thatExpand
Do associated microbial abundances impact marine demosponge pumping rates and tissue densities?
TLDR
Density and pumping rate differences suggest that evolutionary differences between HMA and LMA species may have resulted in profound morphological and physiological differences between the two groups. Expand
Linking abundance and diversity of sponge-associated microbial communities to metabolic differences in host sponges
TLDR
Sequence analysis of the microbial communities showed a diversity of metabolic capabilities among the microbes of the lowδ15N group, which are lacking in the high δ15 N group, further supporting metabolic differences between the two groups. Expand
CRAYFISH FEEDING PREFERENCES FOR FRESHWATER MACROPHYTES: THE INFLUENCE OF PLANT STRUCTURE AND CHEMISTRY
TLDR
The omnivorous crayfish Procambarus clarkii fed selectively on several species of macrophytes, preferring delicate fresh plants that had filamentous or finely-branched architectures, demonstrating that nonstructural traits are important feeding determinants. Expand
The HMA-LMA Dichotomy Revisited: an Electron Microscopical Survey of 56 Sponge Species
TLDR
This study significantly expands previous reports on microbial abundances in sponge tissues and contributes to a better understanding of the HMA-LMA dichotomy in sponge-microbe symbioses. Expand
Palatability and Chemical Defense of Marine Invertebrate Larvae
TLDR
Results of this broad survey cast doubt on the widely accepted notion that virtually all marine larvae are suitable prey for most generalized planktivores, and suggest that unpalatable larvae often may be aposematically colored. Expand
Chemical Defenses of Freshwater Macrophytes Against Crayfish Herbivory
TLDR
The role of plant chemical defenses in generating feeding preferences in generating these preferences was determined by incorporating crude aqueous and organic extracts from each species into palatable foods and comparing feeding on these foods to feeding on control foods lacking these extracts. Expand
Vertical Transmission of a Phylogenetically Complex Microbial Consortium in the Viviparous Sponge Ircinia felix
TLDR
It could be shown that in I. felix, vertical transmission of microorganisms through the larvae is an important mechanism for the establishment of the sponge-microbe association. Expand
Constraints on Chemically Mediated Coevolution: Multiple Functions for Seaweed Secondary Metabolites
TLDR
Diterpene alcohols produced by the brown seaweed Dictyota menstrualis deter feeding by numerous species of abundant herbivores and may prevent fouling organisms from colonizing the surface of this alga. Expand
